Key setbacks in 1943, which included a series of German defeats on the Eastern Front, the <a href=\"https://en.wikipedia.org/wiki/Allied_invasion_of_Sicily\">Allied invasions of Sicily</a> and <a href=\"https://en.wikipedia.org/wiki/Allied_invasion_of_Italy\">Italy</a>, and Allied victories in the Pacific, cost the Axis its initiative and forced it into strategic retreat on all fronts. In 1944, the Western Allies <a href=\"https://en.wikipedia.org/wiki/Normandy_landings\">invaded German-occupied France</a>, while the Soviet Union regained its territorial losses and turned toward Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in <a href=\"https://en.wikipedia.org/wiki/Battle_of_West_Hunan\">Central China</a>, <a href=\"https://en.wikipedia.org/wiki/Second_Guangxi_Campaign\">South China</a> and <a href=\"https://en.wikipedia.org/wiki/Burma_Campaign\">Burma</a>, while the Allies crippled the <a href=\"https://en.wikipedia.org/wiki/Imperial_Japanese_Navy\">Japanese Navy</a> and captured key Western Pacific islands.</p>\n<p>The war in Europe concluded with an <a href=\"https://en.wikipedia.org/wiki/Western_Allied_invasion_of_Germany\">invasion of Germany by the Western Allies</a> and the Soviet Union, culminating in the <a href=\"https://en.wikipedia.org/wiki/Battle_of_Berlin\">capture of Berlin</a> by Soviet troops, the <a href=\"https://en.wikipedia.org/wiki/Death_of_Adolf_Hitler\">suicide of Adolf Hitler</a> and the <a href=\"https://en.wikipedia.org/wiki/German_Instrument_of_Surrender\">German unconditional surrender</a> on <a href=\"https://en.wikipedia.org/wiki/Victory_in_Europe_Day\">8 May 1945</a>. Following the <a href=\"https://en.wikipedia.org/wiki/Potsdam_Declaration\">Potsdam Declaration</a> by the Allies on 26 July 1945 and the refusal of Japan to surrender under its terms, the United States <a href=\"https://en.wikipedia.org/wiki/Atomic_bombings_of_Hiroshima_and_Nagasaki\">dropped atomic bombs</a> on the Japanese cities of <a href=\"https://en.wikipedia.org/wiki/Hiroshima\">Hiroshima</a> and <a href=\"https://en.wikipedia.org/wiki/Nagasaki\">Nagasaki</a> on 6 and 9 August respectively. With an <a href=\"https://en.wikipedia.org/wiki/Operation_Downfall\">invasion of the Japanese archipelago</a> imminent, the possibility of additional atomic bombings, the Soviet entry into the war against Japan and its <a href=\"https://en.wikipedia.org/wiki/Soviet_invasion_of_Manchuria\">invasion of Manchuria</a>, Japan announced its intention to surrender on 15 August 1945, cementing total victory in Asia for the Allies. Tribunals were set up by the Allies and <a href=\"https://en.wikipedia.org/wiki/War_crimes\">war crimes</a> trials were conducted in the wake of the war both <a href=\"https://en.wikipedia.org/wiki/Nuremberg_Trials\">against the Germans</a> and <a href=\"https://en.wikipedia.org/wiki/Japanese_war_crimes#War_crimes_trials\">the Japanese</a>.</p>\n<p>World War II changed the political alignment and social structure of the globe. The <a href=\"https://en.wikipedia.org/wiki/United_Nations\">United Nations</a> (UN) was established to foster international co-operation and prevent future conflicts; the victorious <a href=\"https://en.wikipedia.org/wiki/Great_power\">great powers</a>-China, France, the Soviet Union, the United Kingdom, and the United States-became the <a href=\"https://en.wikipedia.org/wiki/Permanent_members_of_the_United_Nations_Security_Council\">permanent members</a> of its <a href=\"https://en.wikipedia.org/wiki/United_Nations_Security_Council\">Security Council</a>. The Soviet Union and United States emerged as rival <a href=\"https://en.wikipedia.org/wiki/Superpower\">superpowers</a>, setting the stage for the nearly half-century long <a href=\"https://en.wikipedia.org/wiki/Cold_War\">Cold War</a>. In the wake of European devastation, the influence of its great powers waned, triggering the <a href=\"https://en.wikipedia.org/wiki/Decolonisation_of_Africa\">decolonisation of Africa</a> and <a href=\"https://en.wikipedia.org/wiki/Decolonisation_of_Asia\">Asia</a>. Most countries whose industries had been damaged moved towards <a href=\"https://en.wikipedia.org/wiki/Post%E2%80%93World_War_II_economic_expansion\">economic recovery and expansion</a>. Political integration, especially <a href=\"https://en.wikipedia.org/wiki/European_integration\">in Europe</a>, emerged as an effort to end pre-war enmities and create a common identity.</p>\n<h2>Chronology </h2>\n<p>The start of the war in Europe is generally held to be 1 September 1939, beginning with the <a href=\"https://en.wikipedia.org/wiki/Invasion_of_Poland\">German invasion of Poland</a>; the United Kingdom and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the <a href=\"https://en.wikipedia.org/wiki/Second_Sino-Japanese_War\">Second Sino-Japanese War</a> on 7 July 1937, or even the <a href=\"https://en.wikipedia.org/wiki/Japanese_invasion_of_Manchuria\">Japanese invasion of Manchuria</a> on 19 September 1931.</p>\n<p>Others follow the British historian <a href=\"https://en.wikipedia.org/wiki/A.J.P._Taylor\">A.J.P. Taylor</a>, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously, and the two wars merged in 1941. This article uses the conventional dating. Other starting dates sometimes used for World War II include the <a href=\"https://en.wikipedia.org/wiki/Second_Italo-Ethiopian_War\">Italian invasion of Abyssinia</a> on 3 October 1935. The British historian <a href=\"https://en.wikipedia.org/wiki/Antony_Beevor\">Antony Beevor</a> views the beginning of World War II as the <a href=\"https://en.wikipedia.org/wiki/Battles_of_Khalkhin_Gol\">Battles of Khalkhin Gol</a> fought between <a href=\"https://en.wikipedia.org/wiki/Empire_of_Japan\">Japan</a> and the forces of <a href=\"https://en.wikipedia.org/wiki/People%27s_Republic_of_Mongolia\">Mongolia</a> and the <a href=\"https://en.wikipedia.org/wiki/Soviet_Union\">Soviet Union</a> from May to September 1939.</p>\n<p>The exact date of the war's end is also not universally agreed upon. It was generally accepted at the time that the war ended with the <a href=\"https://en.wikipedia.org/wiki/Armistice\">armistice</a> of 14 August 1945 ( <a href=\"https://en.wikipedia.org/wiki/Victory_over_Japan_Day\">V-J Day</a>), rather than the formal <a href=\"https://en.wikipedia.org/wiki/Surrender_of_Japan\">surrender of Japan</a>, which was on 2 September 1945 that officially <a href=\"https://en.wikipedia.org/wiki/End_of_World_War_II_in_Asia\">ended the war in Asia</a>. A <a href=\"https://en.wikipedia.org/wiki/Treaty_of_San_Francisco\">peace treaty with Japan</a> was signed in 1951. A <a href=\"https://en.wikipedia.org/wiki/Treaty_on_the_Final_Settlement_with_Respect_to_Germany\">treaty regarding Germany's future</a> allowed the <a href=\"https://en.wikipedia.org/wiki/German_reunification\">reunification of East and West Germany</a> to take place in 1990 and resolved most post-World War II issues. No formal peace treaty between Japan and the Soviet Union was ever signed.</p>\n<h2>Background </h2>\n<p><a href=\"https://en.wikipedia.org/wiki/World_War_I\">World War I</a> had radically altered the <a href=\"https://en.wikipedia.org/wiki/Geopolitics\">political</a> European map, with the defeat of the <a href=\"https://en.wikipedia.org/wiki/Central_Powers\">Central Powers</a>-including <a href=\"https://en.wikipedia.org/wiki/Austria-Hungary\">Austria-Hungary</a>, <a href=\"https://en.wikipedia.org/wiki/German_Empire\">Germany</a>, <a href=\"https://en.wikipedia.org/wiki/Kingdom_of_Bulgaria\">Bulgaria</a> and the <a href=\"https://en.wikipedia.org/wiki/Ottoman_Empire\">Ottoman Empire</a>-and the 1917 <a href=\"https://en.wikipedia.org/wiki/October_Revolution\">Bolshevik seizure of power</a> in <a href=\"https://en.wikipedia.org/wiki/Russian_Republic\">Russia</a>, which eventually led to the founding of the <a href=\"https://en.wikipedia.org/wiki/Soviet_Union\">Soviet Union</a>. Meanwhile, the victorious <a href=\"https://en.wikipedia.org/wiki/Allies_of_World_War_I\">Allies of World War I</a>, such as France, Belgium, Italy, Romania and Greece, gained territory, and new <a href=\"https://en.wikipedia.org/wiki/Nation-states\">nation-states</a> were created out of the collapse of Austria-Hungary and the Ottoman and <a href=\"https://en.wikipedia.org/wiki/Russian_Empire\">Russian Empires</a>.</p>\n<p>To prevent a future world war, the <a href=\"https://en.wikipedia.org/wiki/League_of_Nations\">League of Nations</a> was created during the <a href=\"https://en.wikipedia.org/wiki/Paris_Peace_Conference,_1919\">1919 Paris Peace Conference</a>. The organisation's primary goals were to prevent armed conflict through <a href=\"https://en.wikipedia.org/wiki/Collective_security\">collective security</a>, military and <a href=\"https://en.wikipedia.org/wiki/Washington_Naval_Treaty\">naval disarmament</a>, and settling international disputes through peaceful negotiations and arbitration.</p>\n<p>Despite strong <a href=\"https://en.wikipedia.org/wiki/Pacifist\">pacifist</a> sentiment <a href=\"https://en.wikipedia.org/wiki/Aftermath_of_World_War_I\">after World War I</a>, its aftermath still caused <a href=\"https://en.wikipedia.org/wiki/Irredentist\">irredentist</a> and <a href=\"https://en.wikipedia.org/wiki/Revanchist\">revanchist</a> <a href=\"https://en.wikipedia.org/wiki/Nationalism\">nationalism</a> in several European states. These sentiments were especially marked in Germany because of the significant territorial, colonial, and financial losses incurred by the <a href=\"https://en.wikipedia.org/wiki/Treaty_of_Versailles\">Treaty of Versailles</a>. Under the treaty, Germany lost around 13 percent of its home territory and all of <a href=\"https://en.wikipedia.org/wiki/German_colonial_empire\">its overseas possessions</a>, while German annexation of other states was prohibited, <a href=\"https://en.wikipedia.org/wiki/World_War_I_reparations\">reparations</a> were imposed, and limits were placed on the size and capability of the country's <a href=\"https://en.wikipedia.org/wiki/Reichswehr\">armed forces</a>.</p>\n<p>The German Empire was dissolved in the <a href=\"https://en.wikipedia.org/wiki/German_Revolution_of_1918%E2%80%931919\">German Revolution of 1918-1919</a>, and a democratic government, later known as the <a href=\"https://en.wikipedia.org/wiki/Weimar_Republic\">Weimar Republic</a>, was created. The interwar period saw strife between supporters of the new republic and hardline opponents on both the <a href=\"https://en.wikipedia.org/wiki/Right-wing_politics\">right</a> and <a href=\"https://en.wikipedia.org/wiki/Left-wing_politics\">left</a>. Italy, as an Entente ally, had made some post-war territorial gains; however, Italian nationalists were angered that the <a href=\"https://en.wikipedia.org/wiki/Treaty_of_London_(1915)\">promises made</a> by the United Kingdom and France to secure Italian entrance into the war were not fulfilled in the peace settlement. From 1922 to 1925, the <a href=\"https://en.wikipedia.org/wiki/Italian_Fascism\">Fascist</a> movement led by <a href=\"https://en.wikipedia.org/wiki/Benito_Mussolini\">Benito Mussolini</a> seized power in Italy with a nationalist, <a href=\"https://en.wikipedia.org/wiki/Totalitarianism\">totalitarian</a>, and <a href=\"https://en.wikipedia.org/wiki/Class_collaboration\">class collaborationist</a> agenda that abolished representative democracy, repressed socialist, left-wing and liberal forces, and pursued an aggressive expansionist foreign policy aimed at making Italy a <a href=\"https://en.wikipedia.org/wiki/World_power\">world power</a>, promising the creation of a \" <a href=\"https://en.wikipedia.org/wiki/New_Roman_Empire\">New Roman Empire</a>\".</p>\n<p><a href=\"https://en.wikipedia.org/wiki/Adolf_Hitler\">Adolf Hitler</a>, after an <a href=\"https://en.wikipedia.org/wiki/Beer_Hall_Putsch\">unsuccessful attempt to overthrow the German government</a> in 1923, eventually <a href=\"https://en.wikipedia.org/wiki/Adolf_Hitler%27s_rise_to_power\">became the Chancellor of Germany</a> in 1933. He abolished democracy, espousing a <a href=\"https://en.wikipedia.org/wiki/New_Order_(Nazism)\">radical, racially motivated revision of the world order</a>, and soon began a massive <a href=\"https://en.wikipedia.org/wiki/German_re-armament\">rearmament campaign</a>. Meanwhile, France, to secure its alliance, <a href=\"https://en.wikipedia.org/wiki/Franco-Italian_Agreement\">allowed Italy a free hand in Ethiopia</a>, which Italy desired as a colonial possession. The situation was aggravated in early 1935 when the <a href=\"https://en.wikipedia.org/wiki/Saar_(League_of_Nations)\">Territory of the Saar Basin</a> was legally reunited with Germany and Hitler repudiated the Treaty of Versailles, accelerated his rearmament programme, and introduced <a href=\"https://en.wikipedia.org/wiki/Conscription\">conscription</a>.</p>\n<p>The <a href=\"https://en.wikipedia.org/wiki/United_Kingdom\">United Kingdom</a>, <a href=\"https://en.wikipedia.org/wiki/France\">France</a> and <a href=\"https://en.wikipedia.org/wiki/Italy\">Italy</a> formed the <a href=\"https://en.wikipedia.org/wiki/Stresa_Front\">Stresa Front</a> in April 1935 in order to contain Germany, a key step towards <a href=\"https://en.wikipedia.org/wiki/Military_globalization\">military globalization</a>; however, that June, the United Kingdom made an <a href=\"https://en.wikipedia.org/wiki/Anglo-German_Naval_Agreement\">independent naval agreement</a> with Germany, easing prior restrictions. The Soviet Union, concerned by <a href=\"https://en.wikipedia.org/wiki/Drang_nach_Osten\">Germany's goals of capturing vast areas of Eastern Europe</a>, drafted a treaty of mutual assistance with France. Before taking effect though, the <a href=\"https://en.wikipedia.org/wiki/Franco-Soviet_pact\">Franco-Soviet pact</a> was required to go through the bureaucracy of the League of Nations, which rendered it essentially toothless. The United States, concerned with events in Europe and Asia, passed the <a href=\"https://en.wikipedia.org/wiki/Neutrality_Acts_of_1930s\">Neutrality Act</a> in August of the same year.</p>\n<p>Hitler defied the Versailles and <a href=\"https://en.wikipedia.org/wiki/Locarno_treaties\">Locarno treaties</a> by <a href=\"https://en.wikipedia.org/wiki/Remilitarization_of_the_Rhineland\">remilitarising the Rhineland</a> in March 1936, encountering little opposition due to <a href=\"https://en.wikipedia.org/wiki/Appeasement\">appeasement</a>. In October 1936, Germany and Italy formed the <a href=\"https://en.wikipedia.org/wiki/Rome%E2%80%93Berlin_Axis\">Rome-Berlin Axis</a>. A month later, Germany and Japan signed the <a href=\"https://en.wikipedia.org/wiki/Anti-Comintern_Pact\">Anti-Comintern Pact</a>, which Italy would join in the following year.</p>\n<p>The <a href=\"https://en.wikipedia.org/wiki/Kuomintang\">Kuomintang</a> (KMT) party in China launched a <a href=\"https://en.wikipedia.org/wiki/Northern_Expedition\">unification campaign</a> against <a href=\"https://en.wikipedia.org/wiki/Warlord_Era\">regional warlords</a> and nominally unified China in the mid-1920s, but was soon embroiled in a <a href=\"https://en.wikipedia.org/wiki/Chinese_Civil_War\">civil war</a> against its former <a href=\"https://en.wikipedia.org/wiki/Chinese_Communist_Party\">Chinese Communist Party</a> allies and <a href=\"https://en.wikipedia.org/wiki/Central_Plains_War\">new regional warlords</a>. In 1931, an <a href=\"https://en.wikipedia.org/wiki/Statism_in_Sh%C5%8Dwa_Japan\">increasingly militaristic</a> <a href=\"https://en.wikipedia.org/wiki/Empire_of_Japan\">Empire of Japan</a>, which had long sought influence in China as the first step of what its government saw as the country's <a href=\"https://en.wikipedia.org/wiki/Hakko_ichiu\">right to rule Asia</a>, used the <a href=\"https://en.wikipedia.org/wiki/Mukden_Incident\">Mukden Incident</a> as a pretext to <a href=\"https://en.wikipedia.org/wiki/Japanese_invasion_of_Manchuria\">launch an invasion of Manchuria</a> and establish the <a href=\"https://en.wikipedia.org/wiki/Puppet_state\">puppet state</a> of <a href=\"https://en.wikipedia.org/wiki/Manchukuo\">Manchukuo</a>.</p>\n<p>China appealed to the <a href=\"https://en.wikipedia.org/wiki/League_of_Nations\">League of Nations</a> to stop the Japanese invasion of Manchuria. Japan withdrew from the League of Nations after being <a href=\"https://en.wikipedia.org/wiki/Lytton_Report\">condemned</a> for its incursion into Manchuria. The two nations then fought several battles, in <a href=\"https://en.wikipedia.org/wiki/28_January_Incident\">Shanghai</a>, <a href=\"https://en.wikipedia.org/wiki/Battle_of_Rehe\">Rehe</a> and <a href=\"https://en.wikipedia.org/wiki/Defense_of_the_Great_Wall\">Hebei</a>, until the <a href=\"https://en.wikipedia.org/wiki/Tanggu_Truce\">Tanggu Truce</a> was signed in 1933. Thereafter, Chinese volunteer forces continued the resistance to Japanese aggression in <a href=\"https://en.wikipedia.org/wiki/Pacification_of_Manchukuo\">Manchuria</a>, and <a href=\"https://en.wikipedia.org/wiki/Actions_in_Inner_Mongolia_(1933%E2%80%931936)\">Chahar and Suiyuan</a>. After the 1936 <a href=\"https://en.wikipedia.org/wiki/Xi%27an_Incident\">Xi'an Incident</a>, the Kuomintang and communist forces agreed on a ceasefire to present a <a href=\"https://en.wikipedia.org/wiki/Second_United_Front\">united front</a> to oppose Japan.</p>\n<h2>Pre-war events </h2>\n<h3>Italian invasion of Ethiopia (1935) </h3>\n<p>The <a href=\"https://en.wikipedia.org/wiki/Second_Italo%E2%80%93Ethiopian_War\">Second Italo-Ethiopian War</a> was a brief <a href=\"https://en.wikipedia.org/wiki/Colonial_war\">colonial war</a> that began in October 1935 and ended in May 1936. The war began with the invasion of the <a href=\"https://en.wikipedia.org/wiki/Ethiopian_Empire\">Ethiopian Empire</a> (also known as <a href=\"https://en.wikipedia.org/wiki/Names_of_Ethiopia\">Abyssinia</a>) by the armed forces of the <a href=\"https://en.wikipedia.org/wiki/Kingdom_of_Italy\">Kingdom of Italy</a> ( <i>Regno d'Italia</i>), which was launched from <a href=\"https://en.wikipedia.org/wiki/Italian_Somaliland\">Italian Somaliland</a> and <a href=\"https://en.wikipedia.org/wiki/Italian_Eritrea\">Eritrea</a>. The war resulted in the <a href=\"https://en.wikipedia.org/wiki/Military_occupation\">military occupation</a> of Ethiopia and its <a href=\"https://en.wikipedia.org/wiki/Annexation\">annexation</a> into the newly created colony of <a href=\"https://en.wikipedia.org/wiki/Italian_East_Africa\">Italian East Africa</a> ( <i>Africa Orientale Italiana</i>, or AOI); in addition it exposed the weakness of the <a href=\"https://en.wikipedia.org/wiki/League_of_Nations\">League of Nations</a> as a force to preserve peace. Both Italy and Ethiopia were member nations, <a href=\"https://en.wikipedia.org/wiki/Appeasement\">but the League did little</a> when the former clearly violated Article X of the League's <a href=\"https://en.wikipedia.org/wiki/Covenant_of_the_League_of_Nations\">Covenant</a>. The United Kingdom and France supported imposing sanctions on Italy for the invasion, but they were not fully enforced and failed to end the Italian invasion. Italy subsequently dropped its objections to Germany's goal of absorbing <a href=\"https://en.wikipedia.org/wiki/Federal_State_of_Austria\">Austria</a>.</p>\n<h3>Spanish Civil War (1936-1939) </h3>\n<p>When civil war broke out in Spain, Hitler and Mussolini lent military support to the <a href=\"https://en.wikipedia.org/wiki/Nationalist_faction_(Spanish_Civil_War)\">Nationalist rebels</a>, led by General <a href=\"https://en.wikipedia.org/wiki/Francisco_Franco\">Francisco Franco</a>. Italy supported the Nationalists to a greater extent than the Nazis did: altogether Mussolini sent to Spain more than 70,000 ground troops and 6,000 aviation personnel, as well as about 720 aircraft. The Soviet Union supported the existing government, the <a href=\"https://en.wikipedia.org/wiki/Second_Spanish_Republic\">Spanish Republic</a>. Over 30,000 foreign volunteers, known as the <a href=\"https://en.wikipedia.org/wiki/International_Brigades\">International Brigades</a>, also fought against the Nationalists. Both Germany and the Soviet Union used this <a href=\"https://en.wikipedia.org/wiki/Proxy_war\">proxy war</a> as an opportunity to test in combat their most advanced weapons and tactics. The Nationalists won the civil war in April 1939; Franco, now dictator, remained officially neutral during World War II but generally favoured the Axis. His greatest collaboration with Germany was the sending of <a href=\"https://en.wikipedia.org/wiki/Blue_Division\">volunteers</a> to fight on the <a href=\"https://en.wikipedia.org/wiki/Eastern_Front_(World_War_II)\">Eastern Front</a>.</p>\n<h3>Japanese invasion of China (1937) </h3>\n<p>In July 1937, Japan captured the former Chinese imperial capital of <a href=\"https://en.wikipedia.org/wiki/Peking\">Peking</a> after instigating the <a href=\"https://en.wikipedia.org/wiki/Marco_Polo_Bridge_Incident\">Marco Polo Bridge Incident</a>, which culminated in the Japanese campaign to invade all of China. The Soviets quickly signed a <a href=\"https://en.wikipedia.org/wiki/Sino-Soviet_Non-Aggression_Pact\">non-aggression pact with China</a> to lend <a href=\"https://en.wikipedia.org/wiki/Materiel\">materiel</a> support, effectively ending China's prior <a href=\"https://en.wikipedia.org/wiki/Sino-German_cooperation_1926%E2%80%931941\">co-operation with Germany</a>. From September to November, the Japanese attacked <a href=\"https://en.wikipedia.org/wiki/Battle_of_Taiyuan\">Taiyuan</a>, engaged the <a href=\"https://en.wikipedia.org/wiki/National_Revolutionary_Army\">Kuomintang Army</a> <a href=\"https://en.wikipedia.org/wiki/Battle_of_Xinkou\">around Xinkou</a>, and fought <a href=\"https://en.wikipedia.org/wiki/Communist_Party_of_China\">Communist forces</a> <a href=\"https://en.wikipedia.org/wiki/Battle_of_Pingxingguan\">in Pingxingguan</a>. <a href=\"https://en.wikipedia.org/wiki/Generalissimo\">Generalissimo</a> <a href=\"https://en.wikipedia.org/wiki/Chiang_Kai-shek\">Chiang Kai-shek</a> deployed his <a href=\"https://en.wikipedia.org/wiki/German-trained_divisions_in_the_National_Revolutionary_Army\">best army</a> to <a href=\"https://en.wikipedia.org/wiki/Battle_of_Shanghai\">defend Shanghai</a>, but, after three months of fighting, Shanghai fell. The Japanese continued to push the Chinese forces back, <a href=\"https://en.wikipedia.org/wiki/Battle_of_Nanking\">capturing the capital Nanking</a> in December 1937. After the fall of Nanking, tens of thousands if not hundreds of thousands of Chinese civilians and disarmed combatants were <a href=\"https://en.wikipedia.org/wiki/Nanking_Massacre\">murdered by the Japanese</a>.</p>\n<p>In March 1938, Nationalist Chinese forces won their <a href=\"https://en.wikipedia.org/wiki/Battle_of_Taierzhuang\">first major victory at Taierzhuang</a> but then the city of <a href=\"https://en.wikipedia.org/wiki/Xuzhou\">Xuzhou</a> <a href=\"https://en.wikipedia.org/wiki/Battle_of_Xuzhou\">was taken by Japanese</a> in May. In June 1938, Chinese forces stalled the Japanese advance by <a href=\"https://en.wikipedia.org/wiki/1938_Yellow_River_flood\">flooding the Yellow River</a>; this manoeuvre bought time for the Chinese to prepare their defences at <a href=\"https://en.wikipedia.org/wiki/Wuhan\">Wuhan</a>, but the <a href=\"https://en.wikipedia.org/wiki/Battle_of_Wuhan\">city was taken</a> by October. Japanese military victories did not bring about the collapse of Chinese resistance that Japan had hoped to achieve; instead the Chinese government relocated inland to <a href=\"https://en.wikipedia.org/wiki/Chongqing\">Chongqing</a> and continued the war.</p>\n<h3>Soviet-Japanese border conflicts </h3>\n<p>In the mid-to-late 1930s, Japanese forces in <a href=\"https://en.wikipedia.org/wiki/Manchukuo\">Manchukuo</a> had sporadic border clashes with the Soviet Union and <a href=\"https://en.wikipedia.org/wiki/Mongolian_People%27s_Republic\">Mongolia</a>. The Japanese doctrine of <a href=\"https://en.wikipedia.org/wiki/Hokushin-ron\">Hokushin-ron</a>, which emphasised Japan's expansion northward, was favoured by the Imperial Army during this time. With the Japanese defeat at <a href=\"https://en.wikipedia.org/wiki/Battles_of_Khalkhin_Gol\">Khalkin Gol</a> in 1939, the ongoing Second Sino-Japanese War and ally Nazi Germany pursuing neutrality with the Soviets, this policy would prove difficult to maintain. Japan and the Soviet Union eventually signed a <a href=\"https://en.wikipedia.org/wiki/Soviet%E2%80%93Japanese_Neutrality_Pact\">Neutrality Pact</a> in April 1941, and Japan adopted the doctrine of <a href=\"https://en.wikipedia.org/wiki/Nanshin-ron\">Nanshin-ron</a>, promoted by the Navy, which took its focus southward, eventually leading to its war with the United States and the Western Allies.</p>\n<h3>European occupations and agreements </h3>\n<p><a href=\"https://en.wikipedia.org/wiki/File:Bundesarchiv_Bild_183-R69173,_M%C3%BCnchener_Abkommen,_Staatschefs.jpg\"><img src=\"https://upload.wikimedia.org/wikipedia/commons/thumb/9/9c/Bundesarchiv_Bild_183-R69173%2C_M%C3%BCnchener_Abkommen%2C_Staatschefs.jpg/220px-Bundesarchiv_Bild_183-R69173%2C_M%C3%BCnchener_Abkommen%2C_Staatschefs.jpg\"></a> </p>\n<p>In Europe, Germany and Italy were becoming more aggressive. In March 1938, Germany <a href=\"https://en.wikipedia.org/wiki/Anschluss\">annexed Austria</a>, again provoking <a href=\"https://en.wikipedia.org/wiki/Appeasement_of_Hitler\">little response</a> from other European powers. Encouraged, Hitler began pressing German claims on the <a href=\"https://en.wikipedia.org/wiki/Sudetenland\">Sudetenland</a>, an area of <a href=\"https://en.wikipedia.org/wiki/Czechoslovakia\">Czechoslovakia</a> with a predominantly <a href=\"https://en.wikipedia.org/wiki/Ethnic_German\">ethnic German</a> population. Soon the United Kingdom and France followed the counsel of British Prime Minister <a href=\"https://en.wikipedia.org/wiki/Neville_Chamberlain\">Neville Chamberlain</a> and conceded this territory to Germany in the <a href=\"https://en.wikipedia.org/wiki/Munich_Agreement\">Munich Agreement</a>, which was made against the wishes of the Czechoslovak government, in exchange for a promise of no further territorial demands. Soon afterwards, Germany and Italy forced Czechoslovakia to <a href=\"https://en.wikipedia.org/wiki/First_Vienna_Award\">cede additional territory</a> to <a href=\"https://en.wikipedia.org/wiki/Hungary\">Hungary</a>, and Poland annexed Czechoslovakia's <a href=\"https://en.wikipedia.org/wiki/Zaolzie\">Zaolzie</a> region.</p>\n<p>Although all of Germany's stated demands had been satisfied by the agreement, privately Hitler was furious that British interference had prevented him from seizing all of Czechoslovakia in one operation. In subsequent speeches Hitler attacked British and Jewish \"war-mongers\" and in January 1939 <a href=\"https://en.wikipedia.org/wiki/Plan_Z\">secretly ordered a major build-up of the German navy</a> to challenge British naval supremacy. In March 1939, <a href=\"https://en.wikipedia.org/wiki/German_occupation_of_Czechoslovakia\">Germany invaded the remainder of Czechoslovakia</a> and subsequently split it into the German <a href=\"https://en.wikipedia.org/wiki/Protectorate_of_Bohemia_and_Moravia\">Protectorate of Bohemia and Moravia</a> and a pro-German <a href=\"https://en.wikipedia.org/wiki/Client_state\">client state</a>, the <a href=\"https://en.wikipedia.org/wiki/Slovak_Republic_(1939%E2%80%931945)\">Slovak Republic</a>. Hitler also delivered the 20 March 1939 <a href=\"https://en.wikipedia.org/wiki/1939_German_ultimatum_to_Lithuania\">ultimatum to Lithuania</a>, forcing the concession of the <a href=\"https://en.wikipedia.org/wiki/Klaip%C4%97da_Region\">Klaip&#279;da Region</a>.</p>\n<p>Greatly alarmed and with Hitler making further demands on the <a href=\"https://en.wikipedia.org/wiki/Free_City_of_Danzig\">Free City of Danzig</a>, the United Kingdom and France <a href=\"https://en.wikipedia.org/wiki/Anglo-Polish_military_alliance#British_Guarantee_to_Poland\">guaranteed their support for Polish independence</a>; when <a href=\"https://en.wikipedia.org/wiki/Italian_invasion_of_Albania\">Italy conquered Albania</a> in April 1939, the same guarantee was extended to Romania and <a href=\"https://en.wikipedia.org/wiki/Kingdom_of_Greece\">Greece</a>. Shortly after the <a href=\"https://en.wikipedia.org/wiki/Franco-Polish_Military_Alliance\">Franco</a>-British pledge to Poland, Germany and Italy formalised their own alliance with the <a href=\"https://en.wikipedia.org/wiki/Pact_of_Steel\">Pact of Steel</a>. Hitler accused the United Kingdom and Poland of trying to \"encircle\" Germany and renounced the <a href=\"https://en.wikipedia.org/wiki/Anglo-German_Naval_Agreement\">Anglo-German Naval Agreement</a> and the <a href=\"https://en.wikipedia.org/wiki/German%E2%80%93Polish_Non-Aggression_Pact\">German-Polish Non-Aggression Pact</a>.</p>\n<p>The situation reached a general crisis in late August as German troops continued to mobilise against the Polish border. In August 23, when tripartite negotiations about a military alliance between France, the United Kingdom and Soviet Union stalled, the Soviet Union signed <a href=\"https://en.wikipedia.org/wiki/Molotov%E2%80%93Ribbentrop_Pact\">a non-aggression pact</a> with Germany. This pact had a secret protocol that defined German and Soviet \"spheres of influence\" (western <a href=\"https://en.wikipedia.org/wiki/Second_Polish_Republic\">Poland</a> and <a href=\"https://en.wikipedia.org/wiki/Lithuania\">Lithuania</a> for Germany; <a href=\"https://en.wikipedia.org/wiki/Territories_of_Poland_annexed_by_the_Soviet_Union\">eastern Poland</a>, Finland, <a href=\"https://en.wikipedia.org/wiki/Estonia\">Estonia</a>, Latvia and <a href=\"https://en.wikipedia.org/wiki/Bessarabia\">Bessarabia</a> for the Soviet Union), and raised the question of continuing Polish independence. The pact neutralized the possibility of Soviet opposition to a campaign against Poland and assured that Germany would not have to face the prospect of a two-front war, as it had in World War I. Immediately after that, Hitler ordered the attack to proceed on 26 August, but upon hearing that the United Kingdom had concluded a formal mutual assistance pact with Poland, and that Italy would maintain neutrality, he decided to delay it.</p>\n<p>In response to British requests for direct negotiations to avoid war, Germany made demands on Poland, which only served as a pretext to worsen relations. On 29 August, Hitler demanded that a Polish <a href=\"https://en.wikipedia.org/wiki/Plenipotentiary\">plenipotentiary</a> immediately travel to Berlin to negotiate the handover of <a href=\"https://en.wikipedia.org/wiki/Danzig\">Danzig</a>, and to allow a <a href=\"https://en.wikipedia.org/wiki/Plebiscite\">plebiscite</a> in the <a href=\"https://en.wikipedia.org/wiki/Polish_Corridor\">Polish Corridor</a> in which the German minority would vote on secession. The Poles refused to comply with the German demands, and on the night of 30-31 August in a stormy meeting with the British ambassador <a href=\"https://en.wikipedia.org/wiki/Neville_Henderson\">Neville Henderson</a>, Ribbentrop declared that Germany considered its claims rejected.</p>\n<h2>Course of the war </h2>\n<h3>War breaks out in Europe (1939-40) </h3>\n<p>On 1 September 1939, Germany <a href=\"https://en.wikipedia.org/wiki/Invasion_of_Poland\">invaded Poland</a> after <a href=\"https://en.wikipedia.org/wiki/Operation_Himmler\">having staged</a> several <a href=\"https://en.wikipedia.org/wiki/Gleiwitz_incident\">false flag border incidents</a> as a pretext to initiate the attack. The <a href=\"https://en.wikipedia.org/wiki/Battle_of_Westerplatte\">Battle of Westerplatte</a> is often described as the first battle of the war. The United Kingdom responded with an ultimatum to Germany to cease military operations, and on 3 September, after the ultimatum was ignored, France, the United Kingdom, <a href=\"https://en.wikipedia.org/wiki/Australia\">Australia</a>, and <a href=\"https://en.wikipedia.org/wiki/Dominion_of_New_Zealand\">New Zealand</a> declared war on Germany. This alliance was joined by <a href=\"https://en.wikipedia.org/wiki/Union_of_South_Africa\">South Africa</a> (6 September) and <a href=\"https://en.wikipedia.org/wiki/Canada\">Canada</a> (10 September). The alliance provided <a href=\"https://en.wikipedia.org/wiki/Phoney_War\">no direct military support</a> to Poland, outside of a <a href=\"https://en.wikipedia.org/wiki/Saar_Offensive\">cautious French probe into the Saarland</a>. The <a href=\"https://en.wikipedia.org/wiki/Allies_of_World_War_II\">Western Allies</a> also began a <a href=\"https://en.wikipedia.org/wiki/Blockade_of_Germany_(1939%E2%80%9345)\">naval blockade of Germany</a>, which aimed to damage the country's economy and war effort. Germany responded by ordering <a href=\"https://en.wikipedia.org/wiki/Submarine_warfare#World_War_II\">U-boat warfare</a> against Allied merchant and warships, which would later escalate into the <a href=\"https://en.wikipedia.org/wiki/Battle_of_the_Atlantic\">Battle of the Atlantic</a>.</p>\n<p>On 8 September, German troops reached the suburbs of <a href=\"https://en.wikipedia.org/wiki/Warsaw\">Warsaw</a>. The Polish <a href=\"https://en.wikipedia.org/wiki/Battle_of_Bzura\">counter offensive</a> to the west halted the German advance for several days, but it was outflanked and encircled by the . Remnants of the Polish army broke through to <a href=\"https://en.wikipedia.org/wiki/Battle_of_Warsaw_(1939)\">besieged Warsaw</a>. On 17 September 1939, after signing a <a href=\"https://en.wikipedia.org/wiki/Battles_of_Khalkhin_Gol\">cease-fire with Japan</a>, the <a href=\"https://en.wikipedia.org/wiki/Soviet_invasion_of_Poland\">Soviets invaded Eastern Poland</a> under a pretext that the Polish state had ostensibly ceased to exist. On 27 September, the Warsaw garrison surrendered to the Germans, and <a href=\"https://en.wikipedia.org/wiki/Samodzielna_Grupa_Operacyjna_Polesie\">the last large operational unit of the Polish Army</a> <a href=\"https://en.wikipedia.org/wiki/Battle_of_Kock_(1939)\">surrendered on 6 October</a>. Despite the military defeat, Poland never surrendered; instead it formed the <a href=\"https://en.wikipedia.org/wiki/Polish_government-in-exile\">Polish government-in-exile</a> and a <a href=\"https://en.wikipedia.org/wiki/Polish_Underground_State\">clandestine state apparatus remained</a> in occupied Poland. A significant part of Polish military personnel <a href=\"https://en.wikipedia.org/wiki/Romanian_Bridgehead\">evacuated to Romania</a> and the Baltic countries; many of them would <a href=\"https://en.wikipedia.org/wiki/Polish_contribution_to_World_War_II\">fight against the Axis in other theatres of the war</a>.</p>\n<p>Germany <a href=\"https://en.wikipedia.org/wiki/Polish_areas_annexed_by_Nazi_Germany\">annexed</a> the western and <a href=\"https://en.wikipedia.org/wiki/General_Government\">occupied</a> the central part of Poland, and the Soviet Union <a href=\"https://en.wikipedia.org/wiki/Polish_areas_annexed_by_Nazi_Germany\">annexed</a> its eastern part; small shares of Polish territory were transferred to <a href=\"https://en.wikipedia.org/wiki/Territorial_changes_of_Poland#World_War_II\">Lithuania</a> and <a href=\"https://en.wikipedia.org/wiki/Slovak_invasion_of_Poland\">Slovakia</a>. On 6 October, Hitler made a public peace overture to the United Kingdom and France, but said that the future of Poland was to be determined exclusively by Germany and the Soviet Union. The proposal was rejected, and Hitler ordered an immediate offensive against France, which would be postponed until the spring of 1940 due to bad weather.</p>\n<p>The Soviet Union forced the <a href=\"https://en.wikipedia.org/wiki/Baltic_countries\">Baltic countries</a>-Estonia, Latvia and Lithuania, the states that were in the Soviet \"sphere of influence\" under the Molotov-Ribbentrop pact-to sign <a href=\"https://en.wikipedia.org/wiki/Background_of_the_occupation_of_the_Baltic_states#Soviet_ultimatums_and_occupation\">\"mutual assistance pacts\"</a> that stipulated stationing Soviet troops in these countries. Soon after, significant Soviet military contingents were moved there. Finland refused to sign a similar pact and rejected ceding part of its territory to the Soviet Union. The Soviet Union invaded Finland in November 1939, and the Soviet Union was expelled from the League of Nations. Despite overwhelming numerical superiority, Soviet military success was modest, and the <a href=\"https://en.wikipedia.org/wiki/Winter_War\">Finno-Soviet war</a> ended in March 1940 with <a href=\"https://en.wikipedia.org/wiki/Moscow_Peace_Treaty\">minimal Finnish concessions</a>.</p>\n<p>In June 1940, the Soviet Union <a href=\"https://en.wikipedia.org/wiki/Soviet_occupation_of_the_Baltic_states_(1940)\">forcibly annexed</a> Estonia, Latvia and Lithuania, and the disputed Romanian regions of <a href=\"https://en.wikipedia.org/wiki/Soviet_occupation_of_Bessarabia_and_Northern_Bukovina\">Bessarabia, Northern Bukovina and Hertza</a>. Meanwhile, Nazi-Soviet political rapprochement and economic co-operation gradually stalled, and both states began preparations for war.</p>\n<h3>Western Europe (1940-41) </h3>\n<p>In April 1940, <a href=\"https://en.wikipedia.org/wiki/Operation_Weser%C3%BCbung\">Germany invaded Denmark and Norway</a> to protect shipments of <a href=\"https://en.wikipedia.org/wiki/Swedish_iron-ore_mining_during_World_War_II\">iron ore from Sweden</a>, which the Allies were <a href=\"https://en.wikipedia.org/wiki/Operation_Wilfred\">attempting to cut off</a>. <a href=\"https://en.wikipedia.org/wiki/Denmark\">Denmark</a> capitulated after a few hours, and <a href=\"https://en.wikipedia.org/wiki/Norway\">Norway</a> was conquered within two months <a href=\"https://en.wikipedia.org/wiki/Norwegian_Campaign\">despite Allied support</a>. <a href=\"https://en.wikipedia.org/wiki/Norway_Debate\">British discontent over the Norwegian campaign</a> led to the appointment of <a href=\"https://en.wikipedia.org/wiki/Winston_Churchill\">Winston Churchill</a> as Prime Minister on 10May 1940.</p>\n<p>On the same day, Germany <a href=\"https://en.wikipedia.org/wiki/Battle_of_France\">launched an offensive against France</a>. To circumvent the strong <a href=\"https://en.wikipedia.org/wiki/Maginot_Line\">Maginot Line</a> fortifications on the Franco-German border, Germany directed its attack at the neutral nations of <a href=\"https://en.wikipedia.org/wiki/Battle_of_Belgium\">Belgium</a>, <a href=\"https://en.wikipedia.org/wiki/Battle_of_the_Netherlands\">the Netherlands</a>, and <a href=\"https://en.wikipedia.org/wiki/German_invasion_of_Luxembourg\">Luxembourg</a>. The Germans carried out a flanking manoeuvre through the <a href=\"https://en.wikipedia.org/wiki/Ardennes\">Ardennes</a> region, which was mistakenly perceived by Allies as an impenetrable natural barrier against armoured vehicles. By successfully implementing new <a href=\"https://en.wikipedia.org/wiki/Blitzkrieg\">blitzkrieg</a> tactics, the <i>Wehrmacht</i> rapidly advanced to the Channel and cut off the Allied forces in Belgium, trapping the bulk of the Allied armies in a cauldron on the Franco-Belgian border near Lille. The United Kingdom was able <a href=\"https://en.wikipedia.org/wiki/Dunkirk_evacuation\">to evacuate a significant number of Allied troops</a> from the continent by early June, although abandoning almost all of their equipment.</p>\n<p>On 10 June, <a href=\"https://en.wikipedia.org/wiki/Italian_invasion_of_France\">Italy invaded France</a>, declaring war on both France and the United Kingdom. The Germans turned south against the weakened French army, and <a href=\"https://en.wikipedia.org/wiki/Paris_in_World_War_II\">Paris</a> fell to them on 14June. Eight days later <a href=\"https://en.wikipedia.org/wiki/Armistice_of_22_June_1940\">France signed an armistice with Germany</a>; it was divided into <a href=\"https://en.wikipedia.org/wiki/German_military_administration_in_occupied_France_during_World_War_II\">German</a> and <a href=\"https://en.wikipedia.org/wiki/Italian_occupation_of_France\">Italian occupation zones</a>, and an unoccupied <a href=\"https://en.wikipedia.org/wiki/Rump_state\">rump state</a> under the <a href=\"https://en.wikipedia.org/wiki/Vichy_Regime\">Vichy Regime</a>, which, though officially neutral, was generally aligned with Germany. France kept its fleet, which <a href=\"https://en.wikipedia.org/wiki/Attack_on_Mers-el-K%C3%A9bir\">the United Kingdom attacked</a> on 3July in an attempt to prevent its seizure by Germany.</p>\n<p><a href=\"https://en.wikipedia.org/wiki/File:View_from_St_Paul%27s_Cathedral_after_the_Blitz.jpg\"><img src=\"https://upload.wikimedia.org/wikipedia/commons/thumb/5/5d/View_from_St_Paul%27s_Cathedral_after_the_Blitz.jpg/220px-View_from_St_Paul%27s_Cathedral_after_the_Blitz.jpg\"></a> </p>\n<p>The <a href=\"https://en.wikipedia.org/wiki/Battle_of_Britain\">Battle of Britain</a> began in early July with <a href=\"https://en.wikipedia.org/wiki/Kanalkampf\">Luftwaffe attacks on shipping and harbours</a>. The United Kingdom rejected Hitler's ultimatum, and the <a href=\"https://en.wikipedia.org/wiki/Adlertag\">German air superiority campaign</a> started in August but failed to defeat <a href=\"https://en.wikipedia.org/wiki/RAF_Fighter_Command\">RAF Fighter Command</a>. Due to this the <a href=\"https://en.wikipedia.org/wiki/Operation_Sea_Lion\">proposed German invasion of Britain</a> was postponed indefinitely on 17September. The German <a href=\"https://en.wikipedia.org/wiki/Strategic_bombing\">strategic bombing</a> offensive intensified with night attacks on London and other cities in <a href=\"https://en.wikipedia.org/wiki/The_Blitz\">the Blitz</a>, but failed to significantly disrupt the British war effort and largely ended in May 1941.</p>\n<p>Using newly captured French ports, the German Navy <a href=\"https://en.wikipedia.org/wiki/Battle_of_the_Atlantic#'Happy_Time'_(June_1940_%E2%80%93_February_1941)\">enjoyed success</a> against an over-extended <a href=\"https://en.wikipedia.org/wiki/Royal_Navy\">Royal Navy</a>, using <a href=\"https://en.wikipedia.org/wiki/U-boat\">U-boats</a> against British shipping in the <a href=\"https://en.wikipedia.org/wiki/Battle_of_the_Atlantic\">Atlantic</a>. The British <a href=\"https://en.wikipedia.org/wiki/Home_Fleet\">Home Fleet</a> scored a significant victory on 27May 1941 by <a href=\"https://en.wikipedia.org/wiki/Last_battle_of_the_battleship_Bismarck\">sinking the German battleship <i>Bismarck</i></a>.</p>\n<p>In November 1939, the United States was taking measures to assist China and the Western Allies, and amended the <a href=\"https://en.wikipedia.org/wiki/Neutrality_Acts_of_1930s\">Neutrality Act</a> to allow <a href=\"https://en.wikipedia.org/wiki/Cash_and_carry_(World_War_II)\">\"cash and carry\"</a> purchases by the Allies. In 1940, following the German capture of Paris, the size of the <a href=\"https://en.wikipedia.org/wiki/United_States_Navy\">United States Navy</a> was <a href=\"https://en.wikipedia.org/wiki/Two-Ocean_Navy_Act\">significantly increased</a>. In September the United States further agreed to a <a href=\"https://en.wikipedia.org/wiki/Destroyers_for_Bases_Agreement\">trade of American destroyers for British bases</a>. Still, a large majority of the American public continued to oppose any direct military intervention in the conflict well into 1941. In December 1940 Roosevelt accused Hitler of planning world conquest and ruled out any negotiations as useless, calling for the United States to become an \" <a href=\"https://en.wikipedia.org/wiki/Arsenal_of_Democracy\">arsenal of democracy</a>\" and promoting <a href=\"https://en.wikipedia.org/wiki/Lend-Lease\">Lend-Lease</a> programmes of aid to support the British war effort. The United States started strategic planning to prepare for a full-scale offensive against Germany.</p>\n<p>At the end of September 1940, the <a href=\"https://en.wikipedia.org/wiki/Tripartite_Pact\">Tripartite Pact</a> formally united Japan, Italy and Germany as the <a href=\"https://en.wikipedia.org/wiki/Axis_Powers\">Axis Powers</a>. The Tripartite Pact stipulated that any country, with the exception of the Soviet Union, which attacked any Axis Power would be forced to go to war against all three. The Axis expanded in November 1940 when Hungary, Slovakia and <a href=\"https://en.wikipedia.org/wiki/Kingdom_of_Romania\">Romania</a> joined. <a href=\"https://en.wikipedia.org/wiki/Romania_in_World_War_II\">Romania</a> and <a href=\"https://en.wikipedia.org/wiki/Hungary_in_World_War_II\">Hungary</a> would make major contributions to the Axis war against the Soviet Union, in Romania's case partially to recapture <a href=\"https://en.wikipedia.org/wiki/Soviet_occupation_of_Bessarabia_and_Northern_Bukovina\">territory ceded to the Soviet Union</a>.</p>\n<h3>Mediterranean (1940-41) </h3>\n<p>In early June 1940 the Italian <i>Regia aeronautica</i> <a href=\"https://en.wikipedia.org/wiki/Siege_of_Malta_(World_War_II)\">attacked and besieged Malta</a>, a British possession. In late summer through early autumn Italy <a href=\"https://en.wikipedia.org/wiki/Italian_conquest_of_British_Somaliland\">conquered British Somaliland</a> and made an <a href=\"https://en.wikipedia.org/wiki/Italian_invasion_of_Egypt\">incursion into British-held Egypt</a>. In October <a href=\"https://en.wikipedia.org/wiki/Greco-Italian_War\">Italy attacked Greece</a>, but the attack was repulsed with heavy Italian casualties; the campaign ended within days with minor territorial changes. Germany started preparation for an invasion of the Balkans to assist Italy, to prevent the British from gaining a foothold there, which would be a potential threat for Romanian oil fields, and to strike against the British dominance of the Mediterranean.</p>\n<p>In December 1940, British Empire forces began <a href=\"https://en.wikipedia.org/wiki/Operation_Compass\">counter-offensives</a> against Italian forces in Egypt and <a href=\"https://en.wikipedia.org/wiki/East_African_Campaign_(World_War_II)#Allied_counter-offensive\">Italian East Africa</a>. The offensives were highly successful; by early February 1941 Italy had lost control of eastern Libya, and large numbers of Italian troops had been taken prisoner. The <a href=\"https://en.wikipedia.org/wiki/Regia_Marina\">Italian Navy</a> also suffered significant defeats, with the Royal Navy putting three Italian battleships out of commission by a <a href=\"https://en.wikipedia.org/wiki/Battle_of_Taranto\">carrier attack at Taranto</a> and neutralising several more warships at the <a href=\"https://en.wikipedia.org/wiki/Battle_of_Cape_Matapan\">Battle of Cape Matapan</a>.</p>\n<p>Italian defeats prompted Germany to <a href=\"https://en.wikipedia.org/wiki/Operation_Sonnenblume\">deploy an expeditionary force</a> to North Africa, and at the end of March 1941 <a href=\"https://en.wikipedia.org/wiki/Erwin_Rommel\">Rommel</a>'s <a href=\"https://en.wikipedia.org/wiki/Afrika_Korps\">Afrika Korps</a> <a href=\"https://en.wikipedia.org/wiki/Western_Desert_Campaign\">launched an offensive</a> which drove back the Commonwealth forces. In under a month, Axis forces advanced to western Egypt and <a href=\"https://en.wikipedia.org/wiki/Siege_of_Tobruk\">besieged the port of Tobruk</a>.</p>\n<p>By late March 1941 <a href=\"https://en.wikipedia.org/wiki/Bulgaria\">Bulgaria</a> and <a href=\"https://en.wikipedia.org/wiki/Yugoslavia\">Yugoslavia</a> signed the <a href=\"https://en.wikipedia.org/wiki/Tripartite_Pact\">Tripartite Pact</a>. However, the Yugoslav government was <a href=\"https://en.wikipedia.org/wiki/Yugoslav_coup_d%27%C3%A9tat\">overthrown two days later</a> by pro-British nationalists. Germany responded with simultaneous invasions of both <a href=\"https://en.wikipedia.org/wiki/Invasion_of_Yugoslavia\">Yugoslavia</a> and <a href=\"https://en.wikipedia.org/wiki/Battle_of_Greece\">Greece</a>, commencing on 6 April 1941; both nations were forced to surrender within the month. The airborne <a href=\"https://en.wikipedia.org/wiki/Battle_of_Crete\">invasion of the Greek island of Crete</a> at the end of May completed the German conquest of the Balkans. Although the Axis victory was swift, bitter and large-scale partisan warfare subsequently broke out against the <a href=\"https://en.wikipedia.org/wiki/Axis_occupation_of_Yugoslavia\">Axis occupation of Yugoslavia</a>, which continued until the end of the war.</p>\n<p>In the Middle East, in May Commonwealth forces <a href=\"https://en.wikipedia.org/wiki/Anglo-Iraqi_War\">quashed an uprising in Iraq</a> which had been supported by German aircraft from bases within Vichy-controlled <a href=\"https://en.wikipedia.org/wiki/French_Mandate_of_Syria\">Syria</a>. Between June and July they <a href=\"https://en.wikipedia.org/wiki/Syria%E2%80%93Lebanon_Campaign\">invaded and occupied the French possessions Syria and Lebanon</a>, with the assistance of the <a href=\"https://en.wikipedia.org/wiki/Free_French\">Free French</a>.</p>\n<h3>Axis attack on the Soviet Union (1941) </h3>\n<p>With the situation in Europe and Asia relatively stable, Germany, Japan, and the Soviet Union made preparations. With the Soviets wary of mounting tensions with Germany and the Japanese planning to take advantage of the European War by seizing resource-rich European possessions in <a href=\"https://en.wikipedia.org/wiki/Southeast_Asia\">Southeast Asia</a>, the two powers signed the <a href=\"https://en.wikipedia.org/wiki/Soviet%E2%80%93Japanese_Neutrality_Pact\">Soviet-Japanese Neutrality Pact</a> in April 1941. By contrast, the Germans were steadily making preparations for an attack on the Soviet Union, massing forces on the Soviet border.</p>\n<p>Hitler believed that the United Kingdom's refusal to end the war was based on the hope that the United States and the Soviet Union would enter the war against Germany sooner or later. He therefore decided to try to strengthen Germany's relations with the Soviets, or failing that to attack and eliminate them as a factor. In November 1940, <a href=\"https://en.wikipedia.org/wiki/German%E2%80%93Soviet_Axis_talks\">negotiations took place</a> to determine if the Soviet Union would join the Tripartite Pact. The Soviets showed some interest, but asked for concessions from Finland, Bulgaria, Turkey, and Japan that Germany considered unacceptable. On 18 December 1940, Hitler issued the directive to prepare for an invasion of the Soviet Union.</p>\n<p>On 22 June 1941, Germany, supported by Italy and Romania, invaded the Soviet Union in <a href=\"https://en.wikipedia.org/wiki/Operation_Barbarossa\">Operation Barbarossa</a>, with Germany accusing the Soviets of plotting against them. They were joined shortly by Finland and Hungary. The primary targets of this surprise offensive were the <a href=\"https://en.wikipedia.org/wiki/Baltic_region\">Baltic region</a>, Moscow and <a href=\"https://en.wikipedia.org/wiki/Ukraine\">Ukraine</a>, with the <a href=\"https://en.wikipedia.org/wiki/Strategic_goal_(military)\">ultimate goal</a> of ending the 1941 campaign near the <a href=\"https://en.wikipedia.org/wiki/A-A_line\">Arkhangelsk-Astrakhan line</a>, from the <a href=\"https://en.wikipedia.org/wiki/Caspian_sea\">Caspian</a> to the <a href=\"https://en.wikipedia.org/wiki/White_Sea\">White Seas</a>. Hitler's objectives were to eliminate the Soviet Union as a military power, exterminate Communism, generate <i><a href=\"https://en.wikipedia.org/wiki/Lebensraum\">Lebensraum</a></i> (\"living space\") by <a href=\"https://en.wikipedia.org/wiki/Generalplan_Ost\">dispossessing the native population</a> and guarantee access to the strategic resources needed to defeat Germany's remaining rivals.</p>\n<p>Although the <a href=\"https://en.wikipedia.org/wiki/Red_Army\">Red Army</a> was preparing for strategic <a href=\"https://en.wikipedia.org/wiki/Counter-offensive\">counter-offensives</a> before the war, <i>Barbarossa</i> forced the <a href=\"https://en.wikipedia.org/wiki/Stavka\">Soviet supreme command</a> to adopt a <a href=\"https://en.wikipedia.org/wiki/Strategic_defence\">strategic defence</a>. During the summer, the Axis made significant gains into Soviet territory, inflicting immense losses in both personnel and materiel. By the middle of August, however, the German <a href=\"https://en.wikipedia.org/wiki/Oberkommando_des_Heeres\">Army High Command</a> decided to <a href=\"https://en.wikipedia.org/wiki/Battle_of_Smolensk_(1941)\">suspend the offensive</a> of a considerably depleted <a href=\"https://en.wikipedia.org/wiki/Army_Group_Centre\">Army Group Centre</a>, and to divert the <a href=\"https://en.wikipedia.org/wiki/2nd_Panzer_Group\">2nd Panzer Group</a> to reinforce troops advancing towards central Ukraine and Leningrad. The <a href=\"https://en.wikipedia.org/wiki/Battle_of_Kiev_(1941)\">Kiev offensive</a> was overwhelmingly successful, resulting in encirclement and elimination of four Soviet armies, and made possible further <a href=\"https://en.wikipedia.org/wiki/Crimean_Campaign\">advance into Crimea</a> and industrially developed Eastern Ukraine (the <a href=\"https://en.wikipedia.org/wiki/First_Battle_of_Kharkov\">First Battle of Kharkov</a>).</p>\n<p>The diversion of three quarters of the Axis troops and the majority of their air forces from France and the central Mediterranean to the <a href=\"https://en.wikipedia.org/wiki/Eastern_Front_(World_War_II)\">Eastern Front</a> prompted the United Kingdom to reconsider its <a href=\"https://en.wikipedia.org/wiki/Grand_strategy\">grand strategy</a>. In July, the UK and the Soviet Union formed a <a href=\"https://en.wikipedia.org/wiki/Anglo-Soviet_Agreement\">military alliance against Germany</a> The British and Soviets <a href=\"https://en.wikipedia.org/wiki/Anglo-Soviet_invasion_of_Iran\">invaded neutral Iran</a> to secure the <a href=\"https://en.wikipedia.org/wiki/Persian_Corridor\">Persian Corridor</a> and Iran's <a href=\"https://en.wikipedia.org/wiki/Oil_field\">oil fields</a>. In August, the United Kingdom and the United States jointly issued the <a href=\"https://en.wikipedia.org/wiki/Atlantic_Charter\">Atlantic Charter</a>.</p>\n<p>By October Axis <a href=\"https://en.wikipedia.org/wiki/Operational_objective\">operational objectives</a> in Ukraine and the Baltic region were achieved, with only the sieges of <a href=\"https://en.wikipedia.org/wiki/Siege_of_Leningrad\">Leningrad</a> and <a href=\"https://en.wikipedia.org/wiki/Siege_of_Sevastopol_(1941%E2%80%9342)\">Sevastopol</a> continuing. A major <a href=\"https://en.wikipedia.org/wiki/Battle_of_Moscow\">offensive against Moscow</a> was renewed; after two months of fierce battles in increasingly harsh weather the German army almost reached the outer suburbs of Moscow, where the exhausted troops were forced to suspend their offensive. Large territorial gains were made by Axis forces, but their campaign had failed to achieve its main objectives: two key cities remained in Soviet hands, the Soviet <a href=\"https://en.wikipedia.org/wiki/Military_capability\">capability to resist</a> was not broken, and the Soviet Union retained a considerable part of its military potential. The <i>blitzkrieg</i> <a href=\"https://en.wikipedia.org/wiki/Phase_(combat)\">phase</a> of the war in Europe had ended.</p>\n<p>By early December, freshly mobilised <a href=\"https://en.wikipedia.org/wiki/Military_reserve_force\">reserves</a> allowed the Soviets to achieve numerical parity with Axis troops. This, as well as <a href=\"https://en.wikipedia.org/wiki/Richard_Sorge#Wartime_intelligence_supplied_by_the_Sorge_Ring\">intelligence data</a> which established that a minimal number of Soviet troops in the East would be sufficient to deter any attack by the Japanese <a href=\"https://en.wikipedia.org/wiki/Kwantung_Army\">Kwantung Army</a>, allowed the Soviets to begin a <a href=\"https://en.wikipedia.org/wiki/Soviet_Offensive_(1941%E2%80%931942)\">massive counter-offensive</a> that started on 5 December all along the front and pushed German troops 100-250 kilometres (62-155 mi) west.</p>\n<h3>War breaks out in the Pacific (1941) </h3>\n<p>In 1939, the United States had renounced its trade treaty with Japan, and beginning with an <a href=\"https://en.wikipedia.org/wiki/Aviation_gasoline\">aviation gasoline</a> ban in July 1940, Japan became subject to increasing economic pressure. During this time, Japan launched its <a href=\"https://en.wikipedia.org/wiki/Battle_of_Changsha_(1939)\">first attack against Changsha</a>, a strategically important Chinese city, but was repulsed by late September. Despite <a href=\"https://en.wikipedia.org/wiki/1939%E2%80%9340_Winter_Offensive\">several offensives</a> by both sides, the war between China and Japan was stalemated by 1940. To increase pressure on China by blocking supply routes, and to better position Japanese forces in the event of a war with the Western powers, Japan invaded and <a href=\"https://en.wikipedia.org/wiki/Japanese_invasion_of_French_Indochina\">occupied northern Indochina</a>. Afterwards, the United States <a href=\"https://en.wikipedia.org/wiki/Embargo\">embargoed</a> iron, steel and mechanical parts against Japan.</p>\n<p>Chinese nationalist forces launched a large-scale <a href=\"https://en.wikipedia.org/wiki/1939%E2%80%9340_Winter_Offensive\">counter-offensive</a> in early 1940. In August, <a href=\"https://en.wikipedia.org/wiki/Communist_Party_of_China\">Chinese communists</a> launched an <a href=\"https://en.wikipedia.org/wiki/Hundred_Regiments_Offensive\">offensive in Central China</a>; in retaliation, Japan instituted <a href=\"https://en.wikipedia.org/wiki/Three_Alls_Policy\">harsh measures</a> in occupied areas to reduce human and material resources for the communists. Continued antipathy between Chinese communist and nationalist forces <a href=\"https://en.wikipedia.org/wiki/New_Fourth_Army_incident\">culminated in armed clashes in January 1941</a>, effectively ending their co-operation. In March, the Japanese 11th army attacked the headquarters of the Chinese 19th army but was repulsed during <a href=\"https://en.wikipedia.org/wiki/Battle_of_Shanggao\">Battle of Shanggao</a>. In September, Japan attempted to <a href=\"https://en.wikipedia.org/wiki/Battle_of_Changsha_(1941)\">take the city of Changsha</a> again and clashed with Chinese nationalist forces.</p>\n<p>German successes in Europe encouraged Japan to increase pressure on European governments in <a href=\"https://en.wikipedia.org/wiki/Southeast_Asia\">Southeast Asia</a>. The Dutch government agreed to provide Japan some oil supplies from the <a href=\"https://en.wikipedia.org/wiki/Dutch_East_Indies\">Dutch East Indies</a>, but negotiations for additional access to their resources ended in failure in June 1941. In July 1941 Japan sent troops to southern Indochina, thus threatening British and Dutch possessions in the Far East. The United States, United Kingdom and other Western governments reacted to this move with a freeze on Japanese assets and a total oil embargo. At the same time, Japan was <a href=\"https://en.wikipedia.org/wiki/Kantokuen\">planning an invasion of the Soviet Far East</a>, intending to capitalise off the German invasion in the west, but abandoned the operation after the sanctions.</p>\n<p>Since early 1941 the United States and Japan had been engaged in negotiations in an attempt to improve their strained relations and end the war in China. During these negotiations Japan advanced a number of proposals which were dismissed by the Americans as inadequate. At the same time the United States, the United Kingdom, and the Netherlands engaged in secret discussions for the joint defence of their territories, in the event of a Japanese attack against any of them. Roosevelt reinforced <a href=\"https://en.wikipedia.org/wiki/Commonwealth_of_the_Philippines\">the Philippines (an American protectorate scheduled for independence in 1946)</a> and warned Japan that the United States would react to Japanese attacks against any \"neighboring countries\".</p>\n<p>Frustrated at the lack of progress and feeling the pinch of the American-British-Dutch sanctions, Japan prepared for war. On 20 November a new government under <a href=\"https://en.wikipedia.org/wiki/Hideki_Tojo\">Hideki Tojo</a> presented an interim proposal as its final offer. It called for the end of American aid to China and for lifting the embargo on the supply of oil and other resources to Japan. In exchange, Japan promised not to launch any attacks in Southeast Asia and to withdraw its forces from southern Indochina. The American counter-proposal of 26 November required that Japan evacuate all of China without conditions and conclude non-aggression pacts with all Pacific powers. That meant Japan was essentially forced to choose between abandoning its ambitions in China, or seizing the natural resources it needed in the Dutch East Indies by force; the Japanese military did not consider the former an option, and many officers considered the oil embargo an unspoken declaration of war.</p>\n<p>Japan planned to rapidly seize European colonies in Asia to create a large defensive perimeter stretching into the Central Pacific. The Japanese would then be free to exploit the resources of Southeast Asia while exhausting the over-stretched Allies by fighting a defensive war. To prevent American intervention while securing the perimeter, it was further planned to neutralise the <a href=\"https://en.wikipedia.org/wiki/United_States_Pacific_Fleet\">United States Pacific Fleet</a> and the American military presence in the Philippines from the outset. On 7 December 1941 (8 December in Asian time zones), Japan attacked British and American holdings with near-simultaneous <a href=\"https://en.wikipedia.org/wiki/Japanese_expansion_(1941%E2%80%931942)\">offensives against Southeast Asia and the Central Pacific</a>. These included an <a href=\"https://en.wikipedia.org/wiki/Attack_on_Pearl_Harbor\">attack on the American fleets at Pearl Harbor</a> and <a href=\"https://en.wikipedia.org/wiki/Philippines_Campaign_(1941%E2%80%9342)\">the Philippines</a>, <a href=\"https://en.wikipedia.org/wiki/Malayan_Campaign\">landings in Thailand and Malaya</a>, and the <a href=\"https://en.wikipedia.org/wiki/Battle_of_Hong_Kong\">Battle of Hong Kong</a>.</p>\n<p>These attacks led the <a href=\"https://en.wikipedia.org/wiki/United_States_declaration_of_war_on_Japan\">United States</a>, <a href=\"https://en.wikipedia.org/wiki/United_Kingdom_declaration_of_war_on_Japan\">United Kingdom</a>, China, Australia and several other states to formally declare war on Japan, whereas the Soviet Union, being heavily involved in large-scale hostilities with European Axis countries, maintained its neutrality agreement with Japan. Germany, followed by the other Axis states, declared war on the United States in solidarity with Japan, citing as justification the American attacks on German war vessels that had been ordered by Roosevelt.</p>\n<h3>Axis advance stalls (1942-43) </h3>\n<p>On 1 January 1942, the <a href=\"https://en.wikipedia.org/wiki/Four_Policemen\">Allied Big Four</a>-the Soviet Union, China, the United Kingdom and the United States-and 22 smaller or exiled governments issued the <a href=\"https://en.wikipedia.org/wiki/Declaration_by_United_Nations\">Declaration by United Nations</a>, thereby affirming the <a href=\"https://en.wikipedia.org/wiki/Atlantic_Charter\">Atlantic Charter</a>, and agreeing to not to sign a <a href=\"https://en.wikipedia.org/wiki/Separate_peace\">separate peace</a> with the Axis powers.</p>\n<p>During 1942, Allied officials debated on the appropriate <a href=\"https://en.wikipedia.org/wiki/Grand_strategy\">grand strategy</a> to pursue. All agreed that <a href=\"https://en.wikipedia.org/wiki/Europe_first\">defeating Germany</a> was the primary objective. The Americans favoured a straightforward, <a href=\"https://en.wikipedia.org/wiki/Operation_Sledgehammer\">large-scale attack</a> on Germany through France. The Soviets were also demanding a second front. The British, on the other hand, argued that military operations should target peripheral areas to wear out German strength, leading to increasing demoralisation, and bolster resistance forces. Germany itself would be subject to a heavy bombing campaign. An offensive against Germany would then be launched primarily by Allied armour without using large-scale armies. Eventually, the British persuaded the Americans that a landing in France was infeasible in 1942 and they should instead focus on driving the Axis out of North Africa.</p>\n<p>At the <a href=\"https://en.wikipedia.org/wiki/Casablanca_Conference\">Casablanca Conference</a> in early 1943, the Allies reiterated the statements issued in the 1942 Declaration, and demanded the <a href=\"https://en.wikipedia.org/wiki/Unconditional_surrender\">unconditional surrender</a> of their enemies. The British and Americans agreed to continue to press the initiative in the Mediterranean by invading Sicily to fully secure the Mediterranean supply routes. Although the British argued for further operations in the Balkans to bring Turkey into the war, in May 1943, the Americans extracted a British commitment to limit Allied operations in the Mediterranean to an invasion of the Italian mainland and to invade France in 1944.</p>\n<h4>Pacific (1942-43) </h4>\n<p><a href=\"https://en.wikipedia.org/wiki/File:Second_world_war_asia_1937-1942_map_en6.png\"><img src=\"https://upload.wikimedia.org/wikipedia/commons/thumb/5/52/Second_world_war_asia_1937-1942_map_en6.png/310px-Second_world_war_asia_1937-1942_map_en6.png\"></a> </p>\n<p>By the end of April 1942, Japan and its ally Thailand had almost fully conquered <a href=\"https://en.wikipedia.org/wiki/Japanese_conquest_of_Burma\">Burma</a>, <a href=\"https://en.wikipedia.org/wiki/Battle_of_Malaya\">Malaya</a>, <a href=\"https://en.wikipedia.org/wiki/Dutch_East_Indies_campaign\">the Dutch East Indies</a>, <a href=\"https://en.wikipedia.org/wiki/Battle_of_Singapore\">Singapore</a>, and <a href=\"https://en.wikipedia.org/wiki/Battle_of_Rabaul_(1942)\">Rabaul</a>, inflicting severe losses on Allied troops and taking a large number of prisoners. Despite stubborn <a href=\"https://en.wikipedia.org/wiki/Philippines_Campaign_(1941%E2%80%9342)\">resistance</a> by Filipino and US forces, the <a href=\"https://en.wikipedia.org/wiki/Philippine_Commonwealth\">Philippine Commonwealth</a> was eventually captured in May 1942, forcing its government into exile. On 16 April, in Burma, 7,000 British soldiers were encircled by the Japanese 33rd Division during the <a href=\"https://en.wikipedia.org/wiki/Battle_of_Yenangyaung\">Battle of Yenangyaung</a> and rescued by the Chinese 38th Division. Japanese forces also achieved naval victories in the <a href=\"https://en.wikipedia.org/wiki/Sinking_of_Prince_of_Wales_and_Repulse\">South China Sea</a>, <a href=\"https://en.wikipedia.org/wiki/Battle_of_the_Java_Sea\">Java Sea</a> and <a href=\"https://en.wikipedia.org/wiki/Indian_Ocean_raid_(1942)\">Indian Ocean</a>, and <a href=\"https://en.wikipedia.org/wiki/Bombing_of_Darwin\">bombed the Allied naval base</a> at <a href=\"https://en.wikipedia.org/wiki/Darwin,_Northern_Territory\">Darwin</a>, Australia. In January 1942, the only Allied success against Japan was a Chinese <a href=\"https://en.wikipedia.org/wiki/Battle_of_Changsha_(1942)\">victory at Changsha</a>. These easy victories over unprepared US and European opponents left Japan overconfident, as well as overextended.</p>\n<p>In early May 1942, Japan initiated operations to <a href=\"https://en.wikipedia.org/wiki/Operation_Mo\">capture Port Moresby</a> by <a href=\"https://en.wikipedia.org/wiki/Amphibious_assault\">amphibious assault</a> and thus sever communications and supply lines between the United States and Australia. The planned invasion was thwarted when an Allied task force, centred on two American fleet carriers, fought Japanese naval forces to a draw in the <a href=\"https://en.wikipedia.org/wiki/Battle_of_the_Coral_Sea\">Battle of the Coral Sea</a>. Japan's next plan, motivated by the earlier <a href=\"https://en.wikipedia.org/wiki/Doolittle_Raid\">Doolittle Raid</a>, was to seize <a href=\"https://en.wikipedia.org/wiki/Midway_Atoll\">Midway Atoll</a> and lure American carriers into battle to be eliminated; as a diversion, Japan would also send forces to <a href=\"https://en.wikipedia.org/wiki/Aleutian_Islands_Campaign\">occupy the Aleutian Islands</a> in Alaska. In mid-May, Japan started the <a href=\"https://en.wikipedia.org/wiki/Zhejiang-Jiangxi_Campaign\">Zhejiang-Jiangxi Campaign</a> in China, with the goal of inflicting retribution on the Chinese who aided the surviving American airmen in the Doolittle Raid by destroying air bases and fighting against the Chinese 23rd and 32nd Army Groups. In early June, Japan put its operations into action, but the Americans, having broken <a href=\"https://en.wikipedia.org/wiki/Japanese_naval_codes\">Japanese naval codes</a> in late May, were fully aware of the plans and order of battle, and used this knowledge to achieve a decisive <a href=\"https://en.wikipedia.org/wiki/Battle_of_Midway\">victory at Midway</a> over the <a href=\"https://en.wikipedia.org/wiki/Imperial_Japanese_Navy\">Imperial Japanese Navy</a>.</p>\n<p>With its capacity for aggressive action greatly diminished as a result of the Midway battle, Japan chose to focus on a belated attempt to capture <a href=\"https://en.wikipedia.org/wiki/Port_Moresby\">Port Moresby</a> by an <a href=\"https://en.wikipedia.org/wiki/Kokoda_Track_campaign\">overland campaign</a> in the <a href=\"https://en.wikipedia.org/wiki/Territory_of_Papua\">Territory of Papua</a>. The Americans planned a counter-attack against Japanese positions in the southern <a href=\"https://en.wikipedia.org/wiki/Solomon_Islands\">Solomon Islands</a>, primarily <a href=\"https://en.wikipedia.org/wiki/Guadalcanal\">Guadalcanal</a>, as a first step towards capturing <a href=\"https://en.wikipedia.org/wiki/Rabaul\">Rabaul</a>, the main Japanese base in Southeast Asia.</p>\n<p>Both plans started in July, but by mid-September, <a href=\"https://en.wikipedia.org/wiki/Guadalcanal_Campaign\">the Battle for Guadalcanal</a> took priority for the Japanese, and troops in New Guinea were ordered to withdraw from the Port Moresby area to the <a href=\"https://en.wikipedia.org/wiki/Oro_Province\">northern part of the island</a>, where they faced Australian and United States troops in the <a href=\"https://en.wikipedia.org/wiki/Battle_of_Buna-Gona\">Battle of Buna-Gona</a>. Guadalcanal soon became a focal point for both sides with heavy commitments of troops and ships in the battle for Guadalcanal. By the start of 1943, the Japanese were defeated on the island and <a href=\"https://en.wikipedia.org/wiki/Operation_Ke\">withdrew their troops</a>. In Burma, Commonwealth forces mounted two operations. The first, <a href=\"https://en.wikipedia.org/wiki/Arakan_Campaign_1942%E2%80%9343\">an offensive into the Arakan region</a> in late 1942, went disastrously, forcing a retreat back to India by May 1943. The second was the <a href=\"https://en.wikipedia.org/wiki/Operation_Longcloth\">insertion of irregular forces</a> behind Japanese front-lines in February which, by the end of April, had achieved mixed results.</p>\n<h4>Eastern Front (1942-43) </h4>\n<p>Despite considerable losses, in early 1942 Germany and its allies stopped a major Soviet offensive in central and southern Russia, keeping most territorial gains they had achieved during the previous year. In May the Germans defeated Soviet offensives in the <a href=\"https://en.wikipedia.org/wiki/Battle_of_the_Kerch_Peninsula\">Kerch Peninsula</a> and at <a href=\"https://en.wikipedia.org/wiki/Second_Battle_of_Kharkov\">Kharkov</a>, and then launched their main <a href=\"https://en.wikipedia.org/wiki/Case_Blue\">summer offensive</a> against southern Russia in June 1942, to seize the <a href=\"https://en.wikipedia.org/wiki/Baku_Oil_Fields\">oil fields of the Caucasus</a> and occupy <a href=\"https://en.wikipedia.org/wiki/Kuban\">Kuban</a> <a href=\"https://en.wikipedia.org/wiki/Steppe\">steppe</a>, while maintaining positions on the northern and central areas of the front. The Germans split <a href=\"https://en.wikipedia.org/wiki/Army_Group_South\">Army Group South</a> into two groups: <a href=\"https://en.wikipedia.org/wiki/Army_Group_A\">Army Group A</a> advanced to the lower <a href=\"https://en.wikipedia.org/wiki/Don_River_(Russia)\">Don River</a> and struck south-east to the Caucasus, while <a href=\"https://en.wikipedia.org/wiki/Army_Group_B\">Army Group B</a> headed towards the <a href=\"https://en.wikipedia.org/wiki/Volga_River\">Volga River</a>. The Soviets decided to make their stand at Stalingrad on the Volga.</p>\n<p>By mid-November, the Germans had <a href=\"https://en.wikipedia.org/wiki/Battle_of_Stalingrad\">nearly taken Stalingrad</a> in bitter <a href=\"https://en.wikipedia.org/wiki/Urban_warfare\">street fighting</a>. The Soviets began their second winter counter-offensive, starting with an <a href=\"https://en.wikipedia.org/wiki/Operation_Uranus\">encirclement of German forces at Stalingrad</a>, and an assault on the <a href=\"https://en.wikipedia.org/wiki/Operation_Mars\">Rzhev salient near Moscow</a>, though the latter failed disastrously. By early February 1943, the German Army had taken tremendous losses; German troops at Stalingrad had been forced to surrender, and the front-line had been pushed back beyond its position before the summer offensive. In mid-February, after the Soviet push had tapered off, the Germans launched another <a href=\"https://en.wikipedia.org/wiki/Third_Battle_of_Kharkov\">attack on Kharkov</a>, creating a <a href=\"https://en.wikipedia.org/wiki/Salients,_re-entrants_and_pockets\">salient</a> in their front line around the Soviet city of <a href=\"https://en.wikipedia.org/wiki/Kursk\">Kursk</a>.</p>\n<h4>Western Europe/Atlantic and Mediterranean (1942-43) </h4>\n<p>Exploiting poor American naval command decisions, <a href=\"https://en.wikipedia.org/wiki/Second_Happy_Time\">the German navy ravaged Allied shipping off the American Atlantic coast</a>. By November 1941, Commonwealth forces had launched a counter-offensive, <a href=\"https://en.wikipedia.org/wiki/Operation_Crusader\">Operation Crusader</a>, in North Africa, and reclaimed all the gains the Germans and Italians had made. In North Africa, the Germans launched an offensive in January, pushing the British back to positions at the <a href=\"https://en.wikipedia.org/wiki/Gazala_Line\">Gazala Line</a> by early February, followed by a temporary lull in combat which Germany used to prepare for their upcoming offensives. Concerns the Japanese might use bases in Vichy-held <a href=\"https://en.wikipedia.org/wiki/Madagascar\">Madagascar</a> caused the British to <a href=\"https://en.wikipedia.org/wiki/Battle_of_Madagascar\">invade the island</a> in early May 1942. An Axis <a href=\"https://en.wikipedia.org/wiki/Battle_of_Gazala\">offensive in Libya</a> forced an Allied retreat deep inside Egypt until Axis forces were <a href=\"https://en.wikipedia.org/wiki/First_Battle_of_El_Alamein\">stopped at El Alamein</a>. On the Continent, raids of Allied <a href=\"https://en.wikipedia.org/wiki/Commando\">commandos</a> on strategic targets, culminating in the disastrous <a href=\"https://en.wikipedia.org/wiki/Dieppe_Raid\">Dieppe Raid</a>, demonstrated the Western Allies' inability to launch an invasion of continental Europe without much better preparation, equipment, and operational security.</p>\n<p>In August 1942, the Allies succeeded in repelling a <a href=\"https://en.wikipedia.org/wiki/Battle_of_Alam_el_Halfa\">second attack against El Alamein</a> and, at a high cost, managed to <a href=\"https://en.wikipedia.org/wiki/Operation_Pedestal\">deliver desperately needed supplies to the besieged Malta</a>. A few months later, the Allies <a href=\"https://en.wikipedia.org/wiki/Second_Battle_of_El_Alamein\">commenced an attack of their own</a> in Egypt, dislodging the Axis forces and beginning a drive west across Libya. This attack was followed up shortly after by <a href=\"https://en.wikipedia.org/wiki/Operation_Torch\">Anglo-American landings in French North Africa</a>, which resulted in the region joining the Allies. Hitler responded to the French colony's defection by ordering the <a href=\"https://en.wikipedia.org/wiki/Case_Anton\">occupation of Vichy France</a>; although Vichy forces did not resist this violation of the armistice, they managed to <a href=\"https://en.wikipedia.org/wiki/Scuttling_of_the_French_fleet_in_Toulon\">scuttle their fleet</a> to prevent its capture by German forces. The Axis forces in Africa withdrew into <a href=\"https://en.wikipedia.org/wiki/Tunisia\">Tunisia</a>, which was <a href=\"https://en.wikipedia.org/wiki/Tunisian_Campaign\">conquered by the Allies</a> in May 1943.</p>\n<p>In June 1943 the British and Americans began <a href=\"https://en.wikipedia.org/wiki/Combined_Bomber_Offensive\">a strategic bombing campaign</a> against Germany with a goal to disrupt the war economy, reduce morale, and \" <a href=\"https://en.wikipedia.org/wiki/De-housing\">de-house</a>\" the civilian population. The <a href=\"https://en.wikipedia.org/wiki/Bombing_of_Hamburg_in_World_War_II\">firebombing of Hamburg</a> was among the first attacks in this campaign, inflicting significant casualties and considerable losses on infrastructure of this important industrial centre.</p>\n<h3>Allies gain momentum (1943-44) </h3>\n<p><a href=\"https://en.wikipedia.org/wiki/File:SBD_VB-16_over_USS_Washington_1943.jpg\"><img src=\"https://upload.wikimedia.org/wikipedia/commons/thumb/0/07/SBD_VB-16_over_USS_Washington_1943.jpg/220px-SBD_VB-16_over_USS_Washington_1943.jpg\"></a> </p>\n<p>After the Guadalcanal Campaign, the Allies initiated several operations against Japan in the Pacific. In May 1943, Canadian and US forces were sent to <a href=\"https://en.wikipedia.org/wiki/Aleutian_Islands_Campaign#Allied_response\">eliminate Japanese forces from the Aleutians</a>. Soon after, the United States, with support from Australian and New Zealand forces, began major operations to <a href=\"https://en.wikipedia.org/wiki/Operation_Cartwheel\">isolate Rabaul by capturing surrounding islands</a>, and <a href=\"https://en.wikipedia.org/wiki/Gilbert_and_Marshall_Islands_campaign\">breach the Japanese Central Pacific perimeter at the Gilbert and Marshall Islands</a>. By the end of March 1944, the Allies had completed both of these objectives, and had also <a href=\"https://en.wikipedia.org/wiki/Operation_Hailstone\">neutralised the major Japanese base at Truk</a> in the <a href=\"https://en.wikipedia.org/wiki/Caroline_Islands\">Caroline Islands</a>. In April, the Allies launched an operation to <a href=\"https://en.wikipedia.org/wiki/Western_New_Guinea_campaign\">retake Western New Guinea</a>.</p>\n<p>In the Soviet Union, both the Germans and the Soviets spent the spring and early summer of 1943 preparing for large offensives in central Russia. On 4 July 1943, Germany <a href=\"https://en.wikipedia.org/wiki/Battle_of_Kursk\">attacked Soviet forces around the Kursk Bulge</a>. Within a week, German forces had exhausted themselves against the Soviets' deeply echeloned and well-constructed defences, and for the first time in the war Hitler cancelled the operation before it had achieved tactical or operational success. This decision was partially affected by the Western Allies' <a href=\"https://en.wikipedia.org/wiki/Allied_invasion_of_Sicily\">invasion of Sicily</a> launched on 9 July, which, combined with previous Italian failures, resulted in the ousting and arrest of Mussolini later that month.</p>\n<p>On 12 July 1943, the Soviets launched their own <a href=\"https://en.wikipedia.org/wiki/Operation_Kutuzov\">counter-offensives</a>, thereby dispelling any chance of German victory or even stalemate in the east. The Soviet victory at Kursk marked the end of German superiority, giving the Soviet Union the initiative on the Eastern Front. The Germans tried to stabilise their eastern front along the hastily fortified <a href=\"https://en.wikipedia.org/wiki/Panther%E2%80%93Wotan_line\">Panther-Wotan line</a>, but the Soviets broke through it at <a href=\"https://en.wikipedia.org/wiki/Battle_of_Smolensk_(1943)\">Smolensk</a> and by the <a href=\"https://en.wikipedia.org/wiki/Lower_Dnieper_Offensive\">Lower Dnieper Offensives</a>.</p>\n<p>On 3 September 1943, the Western Allies <a href=\"https://en.wikipedia.org/wiki/Allied_invasion_of_Italy\">invaded the Italian mainland</a>, following <a href=\"https://en.wikipedia.org/wiki/Armistice_of_Cassibile\">Italy's armistice with the Allies</a>. Germany with the help of fascists responded by <a href=\"https://en.wikipedia.org/wiki/Operation_Achse\">disarming</a> Italian forces that were in many places without superior orders, seizing military control of Italian areas, and creating a series of defensive lines. German special forces then <a href=\"https://en.wikipedia.org/wiki/Gran_Sasso_raid\">rescued Mussolini</a>, who then soon established a new client state in German-occupied Italy named the <a href=\"https://en.wikipedia.org/wiki/Italian_Social_Republic\">Italian Social Republic</a>, causing an <a href=\"https://en.wikipedia.org/wiki/Italian_Civil_War\">Italian civil war</a>. The Western Allies fought through several lines until reaching the <a href=\"https://en.wikipedia.org/wiki/Winter_Line\">main German defensive line</a> in mid-November.</p>\n<p>German operations in the Atlantic also suffered. By <a href=\"https://en.wikipedia.org/wiki/Black_May_(1943)\">May 1943, as Allied counter-measures became increasingly effective</a>, the resulting sizeable German submarine losses forced a temporary halt of the German Atlantic naval campaign. In November 1943, <a href=\"https://en.wikipedia.org/wiki/Franklin_D._Roosevelt\">Franklin D. Roosevelt</a> and Winston Churchill met with <a href=\"https://en.wikipedia.org/wiki/Chiang_Kai-shek\">Chiang Kai-shek</a> <a href=\"https://en.wikipedia.org/wiki/Cairo_Conference\">in Cairo</a> and then with Joseph Stalin <a href=\"https://en.wikipedia.org/wiki/Tehran_Conference\">in Tehran</a>. The former conference determined the post-war return of Japanese territory and the military planning for the <a href=\"https://en.wikipedia.org/wiki/Burma_Campaign\">Burma Campaign</a>, while the latter included agreement that the Western Allies would invade Europe in 1944 and that the Soviet Union would declare war on Japan within three months of Germany's defeat.</p>\n<p>From November 1943, during the seven-week <a href=\"https://en.wikipedia.org/wiki/Battle_of_Changde\">Battle of Changde</a>, the Chinese forced Japan to fight a costly war of attrition, while awaiting Allied relief. In January 1944, the Allies launched a <a href=\"https://en.wikipedia.org/wiki/Battle_of_Monte_Cassino\">series of attacks in Italy against the line at Monte Cassino</a> and tried to outflank it with <a href=\"https://en.wikipedia.org/wiki/Operation_Shingle\">landings at Anzio</a>.</p>\n<p>On 27 January 1944, <a href=\"https://en.wikipedia.org/wiki/Leningrad_Front\">Soviet</a> troops launched <a href=\"https://en.wikipedia.org/wiki/Siege_of_Leningrad#Soviet_relief_of_the_siege\">a major offensive</a> that expelled German forces from the <a href=\"https://en.wikipedia.org/wiki/Leningrad_Oblast\">Leningrad region</a>, thereby ending the longest and <a href=\"https://en.wikipedia.org/wiki/List_of_battles_by_casualties#Sieges_and_urban_combat\">most lethal siege in history</a>. The <a href=\"https://en.wikipedia.org/wiki/Leningrad%E2%80%93Novgorod_Offensive\">following Soviet offensive</a> was <a href=\"https://en.wikipedia.org/wiki/Battle_of_Narva_(1944)\">halted on the pre-war Estonian border</a> by the German <a href=\"https://en.wikipedia.org/wiki/Army_Group_North\">Army Group North</a> aided by <a href=\"https://en.wikipedia.org/wiki/Occupation_of_Estonia_by_Nazi_Germany#Estonians_in_German_Military_Units_in_1941%E2%80%931944\">Estonians</a> hoping to <a href=\"https://en.wikipedia.org/wiki/Estonian_government-in-exile#Failure_to_reestablish_independence\">re-establish national independence</a>. This delay slowed subsequent Soviet operations in the <a href=\"https://en.wikipedia.org/wiki/Baltic_Sea\">Baltic Sea</a> region. By late May 1944, the Soviets had <a href=\"https://en.wikipedia.org/wiki/Crimean_Offensive\">liberated Crimea</a>, largely expelled Axis forces from Ukraine, and made <a href=\"https://en.wikipedia.org/wiki/First_Jassy%E2%80%93Kishinev_Offensive\">incursions into Romania</a>, which were repulsed by the Axis troops. The Allied offensives in Italy had succeeded and, at the expense of allowing several German divisions to retreat, on 4 June, Rome was captured.</p>\n<p>The Allies had mixed success in mainland Asia. In March 1944, the Japanese launched the first of two invasions, <a href=\"https://en.wikipedia.org/wiki/Operation_U-Go\">an operation against British positions in Assam, India</a>, and soon besieged Commonwealth positions at <a href=\"https://en.wikipedia.org/wiki/Battle_of_Imphal\">Imphal</a> and <a href=\"https://en.wikipedia.org/wiki/Battle_of_Kohima\">Kohima</a>. In May 1944, British forces mounted a counter-offensive that drove Japanese troops back to Burma by July, and Chinese forces that had <a href=\"https://en.wikipedia.org/wiki/Battle_of_Northern_Burma_and_Western_Yunnan\">invaded northern Burma</a> in late 1943 <a href=\"https://en.wikipedia.org/wiki/Siege_of_Myitkyina\">besieged Japanese troops</a> in <a href=\"https://en.wikipedia.org/wiki/Myitkyina\">Myitkyina</a>. The <a href=\"https://en.wikipedia.org/wiki/Operation_Ichi-Go\">second Japanese invasion</a> of China aimed to destroy China's main fighting forces, secure railways between Japanese-held territory and capture Allied airfields. By June, the Japanese had conquered the province of <a href=\"https://en.wikipedia.org/wiki/Henan\">Henan</a> and begun a <a href=\"https://en.wikipedia.org/wiki/Battle_of_Changsha_(1944)\">new attack on Changsha</a> in <a href=\"https://en.wikipedia.org/wiki/Hunan\">Hunan</a> province.</p>\n<h3>Allies close in (1944) </h3>\n<p>On 6 June 1944 (known as <a href=\"https://en.wikipedia.org/wiki/Normandy_landings\">D-Day</a>), after three years of Soviet pressure, the Western Allies <a href=\"https://en.wikipedia.org/wiki/Invasion_of_Normandy\">invaded northern France</a>. After reassigning several Allied divisions from Italy, they also <a href=\"https://en.wikipedia.org/wiki/Operation_Dragoon\">attacked southern France</a>. These landings were successful, and led to the defeat of the <a href=\"https://en.wikipedia.org/wiki/Falaise_Pocket\">German Army units in France</a>. Paris was <a href=\"https://en.wikipedia.org/wiki/Liberation_of_Paris\">liberated</a> on 25 August by the <a href=\"https://en.wikipedia.org/wiki/French_Resistance\">local resistance</a> assisted by the <a href=\"https://en.wikipedia.org/wiki/Free_French_Forces\">Free French Forces</a>, both led by General <a href=\"https://en.wikipedia.org/wiki/Charles_de_Gaulle\">Charles de Gaulle</a>, and the Western Allies continued to <a href=\"https://en.wikipedia.org/wiki/Allied_advance_from_Paris_to_the_Rhine\">push back German forces</a> in western Europe during the latter part of the year. An attempt to advance into northern Germany spearheaded by <a href=\"https://en.wikipedia.org/wiki/Operation_Market_Garden\">a major airborne operation</a> in the Netherlands failed. After that, the Western Allies slowly pushed into Germany, but <a href=\"https://en.wikipedia.org/wiki/Operation_Queen\">failed to cross the Ruhr river</a> in a large offensive. In Italy, Allied advance also slowed due to the <a href=\"https://en.wikipedia.org/wiki/Gothic_Line\">last major German defensive line</a>.</p>\n<p>On 22 June, the Soviets launched a strategic offensive in Belarus (\" <a href=\"https://en.wikipedia.org/wiki/Operation_Bagration\">Operation Bagration</a>\") that destroyed the German <a href=\"https://en.wikipedia.org/wiki/Army_Group_Centre\">Army Group Centre</a> almost completely. Soon after that, <a href=\"https://en.wikipedia.org/wiki/Lvov%E2%80%93Sandomierz_Offensive\">another Soviet strategic offensive</a> forced German troops from Western Ukraine and Eastern Poland. The Soviets formed the <a href=\"https://en.wikipedia.org/wiki/Polish_Committee_of_National_Liberation\">Polish Committee of National Liberation</a> to control territory in Poland and combat the Polish <a href=\"https://en.wikipedia.org/wiki/Armia_Krajowa\">Armia Krajowa</a>; The Soviet Red Army remained in the <a href=\"https://en.wikipedia.org/wiki/Praga\">Praga</a> district on the other side of the <a href=\"https://en.wikipedia.org/wiki/Vistula\">Vistula</a> and watched passively as the Germans quelled the <a href=\"https://en.wikipedia.org/wiki/Warsaw_Uprising\">Warsaw Uprising</a> initiated by the Armia Krajowa. The <a href=\"https://en.wikipedia.org/wiki/Slovak_National_Uprising\">national uprising</a> in <a href=\"https://en.wikipedia.org/wiki/Slovak_Republic_(1939%E2%80%931945)\">Slovakia</a> was also quelled by the Germans. The Soviet <a href=\"https://en.wikipedia.org/wiki/Red_Army\">Red Army</a>'s <a href=\"https://en.wikipedia.org/wiki/Jassy%E2%80%93Kishinev_Offensive\">strategic offensive in eastern Romania</a> cut off and destroyed the <a href=\"https://en.wikipedia.org/wiki/Army_Group_South_Ukraine\">considerable German troops there</a> and triggered <a href=\"https://en.wikipedia.org/wiki/King_Michael%27s_Coup\">a successful coup d'&#233;tat in Romania</a> and <a href=\"https://en.wikipedia.org/wiki/Bulgarian_coup_d%27%C3%A9tat_of_1944\">in Bulgaria</a>, followed by those countries' shift to the Allied side.</p>\n<p>In September 1944, Soviet troops advanced into <a href=\"https://en.wikipedia.org/wiki/Democratic_Federal_Yugoslavia\">Yugoslavia</a> and forced the rapid withdrawal of German Army Groups <a href=\"https://en.wikipedia.org/wiki/Army_Group_E\">E</a> and <a href=\"https://en.wikipedia.org/wiki/Army_Group_F\">F</a> in <a href=\"https://en.wikipedia.org/wiki/Axis_occupation_of_Greece\">Greece</a>, <a href=\"https://en.wikipedia.org/wiki/Albanian_Kingdom_(1943%E2%80%9344)\">Albania</a> and Yugoslavia to rescue them from being cut off. By this point, the Communist-led <a href=\"https://en.wikipedia.org/wiki/Yugoslav_Partisans\">Partisans</a> under Marshal <a href=\"https://en.wikipedia.org/wiki/Josip_Broz_Tito\">Josip Broz Tito</a>, who had led an <a href=\"https://en.wikipedia.org/wiki/World_War_II_in_Yugoslavia\">increasingly successful guerrilla campaign</a> against the occupation since 1941, controlled much of the territory of Yugoslavia and engaged in delaying efforts against German forces further south. In northern <a href=\"https://en.wikipedia.org/wiki/Serbia_(1941%E2%80%931944)\">Serbia</a>, the Soviet <a href=\"https://en.wikipedia.org/wiki/Red_Army\">Red Army</a>, with limited support from Bulgarian forces, assisted the Partisans in a joint <a href=\"https://en.wikipedia.org/wiki/Belgrade_Offensive\">liberation of the capital city of Belgrade</a> on 20 October. A few days later, the Soviets launched a <a href=\"https://en.wikipedia.org/wiki/Budapest_Offensive\">massive assault</a> against <a href=\"https://en.wikipedia.org/wiki/Operation_Panzerfaust\">German-occupied</a> Hungary that lasted until <a href=\"https://en.wikipedia.org/wiki/Battle_of_Budapest\">the fall of Budapest</a> in February 1945. Unlike impressive Soviet victories in the Balkans, <a href=\"https://en.wikipedia.org/wiki/Continuation_War\">bitter Finnish resistance</a> to the <a href=\"https://en.wikipedia.org/wiki/Vyborg%E2%80%93Petrozavodsk_Offensive\">Soviet offensive</a> in the <a href=\"https://en.wikipedia.org/wiki/Karelian_Isthmus\">Karelian Isthmus</a> denied the Soviets occupation of Finland and led to a <a href=\"https://en.wikipedia.org/wiki/Moscow_Armistice\">Soviet-Finnish armistice</a> on relatively mild conditions, although Finland was forced to <a href=\"https://en.wikipedia.org/wiki/Lapland_War\">fight their former ally Germany</a>.</p>\n<p>By the start of July 1944, Commonwealth forces in Southeast Asia had repelled the Japanese sieges in <a href=\"https://en.wikipedia.org/wiki/Assam\">Assam</a>, pushing the Japanese back to the <a href=\"https://en.wikipedia.org/wiki/Chindwin_River\">Chindwin River</a> while the Chinese captured Myitkyina. In September 1944, Chinese forces <a href=\"https://en.wikipedia.org/wiki/Battle_of_Mount_Song\">captured Mount Song</a> and reopened the <a href=\"https://en.wikipedia.org/wiki/Burma_Road\">Burma Road</a>. In China, the Japanese had more successes, having finally <a href=\"https://en.wikipedia.org/wiki/Battle_of_Changsha_(1944)#Battle_of_Changsha\">captured Changsha</a> in mid-June and the city of <a href=\"https://en.wikipedia.org/wiki/Defense_of_Hengyang\">Hengyang</a> by early August. Soon after, they invaded the province of <a href=\"https://en.wikipedia.org/wiki/Guangxi\">Guangxi</a>, winning major engagements against Chinese forces at <a href=\"https://en.wikipedia.org/wiki/Battle_of_Guilin%E2%80%93Liuzhou\">Guilin and Liuzhou</a> by the end of November and successfully linking up their forces in China and Indochina by mid-December.</p>\n<p>In the Pacific, US forces continued to press back the Japanese perimeter. In mid-June 1944, they began their <a href=\"https://en.wikipedia.org/wiki/Mariana_and_Palau_Islands_campaign\">offensive against the Mariana and Palau islands</a>, and decisively defeated Japanese forces in the <a href=\"https://en.wikipedia.org/wiki/Battle_of_the_Philippine_Sea\">Battle of the Philippine Sea</a>. These defeats led to the resignation of the Japanese Prime Minister, <a href=\"https://en.wikipedia.org/wiki/Hideki_Tojo\">Hideki Tojo</a>, and provided the United States with air bases to launch intensive heavy bomber attacks on the Japanese home islands. In late October, American forces <a href=\"https://en.wikipedia.org/wiki/Battle_of_Leyte\">invaded the Filipino island of Leyte</a>; soon after, Allied naval forces scored another large victory in the <a href=\"https://en.wikipedia.org/wiki/Battle_of_Leyte_Gulf\">Battle of Leyte Gulf</a>, one of the largest naval battles in history.</p>\n<h3>Axis collapse, Allied victory (1944-45) </h3>\n<p>On 16 December 1944, Germany made a last attempt on the Western Front by using most of its remaining reserves to launch <a href=\"https://en.wikipedia.org/wiki/Battle_of_the_Bulge\">a massive counter-offensive in the Ardennes</a> and <a href=\"https://en.wikipedia.org/wiki/Operation_Nordwind\">along the French-German border</a> to split the Western Allies, encircle large portions of Western Allied troops and capture their primary supply port at <a href=\"https://en.wikipedia.org/wiki/Antwerp\">Antwerp</a> to prompt a political settlement. By January, the offensive had been repulsed with no strategic objectives fulfilled. In Italy, the Western Allies remained stalemated at the German defensive line. In mid-January 1945, the Soviets and Poles attacked in Poland, <a href=\"https://en.wikipedia.org/wiki/Vistula%E2%80%93Oder_Offensive\">pushing from the Vistula to the Oder</a> river in Germany, and <a href=\"https://en.wikipedia.org/wiki/East_Prussian_Offensive\">overran East Prussia</a>. On 4 February, Soviet, British and US leaders met for the <a href=\"https://en.wikipedia.org/wiki/Yalta_Conference\">Yalta Conference</a>. They agreed on the occupation of post-war Germany, and on when the Soviet Union would join the war against Japan.</p>\n<p>In February, the Soviets <a href=\"https://en.wikipedia.org/wiki/Silesian_Offensives\">entered Silesia</a> and <a href=\"https://en.wikipedia.org/wiki/East_Pomeranian_Offensive\">Pomerania</a>, while <a href=\"https://en.wikipedia.org/wiki/Western_Allied_invasion_of_Germany\">Western Allies entered western Germany</a> and closed to the <a href=\"https://en.wikipedia.org/wiki/Rhine\">Rhine</a> river. By March, the Western Allies crossed the Rhine <a href=\"https://en.wikipedia.org/wiki/Operation_Plunder\">north</a> and <a href=\"https://en.wikipedia.org/wiki/Remagen\">south</a> of the <a href=\"https://en.wikipedia.org/wiki/Rhine-Ruhr\">Ruhr</a>, <a href=\"https://en.wikipedia.org/wiki/Ruhr_Pocket\">encircling the German Army Group B</a>. In early March, in an attempt to protect its last oil reserves in Hungary and to retake Budapest, Germany launched <a href=\"https://en.wikipedia.org/wiki/Operation_Spring_Awakening\">its last major offensive</a> against Soviet troops near <a href=\"https://en.wikipedia.org/wiki/Lake_Balaton\">Lake Balaton</a>. In two weeks, the offensive had been repulsed, the Soviets advanced to <a href=\"https://en.wikipedia.org/wiki/Vienna_offensive\">Vienna</a>, and captured the city. In early April, Soviet troops <a href=\"https://en.wikipedia.org/wiki/Battle_of_K%C3%B6nigsberg\">captured K&#246;nigsberg</a>, while the Western Allies finally <a href=\"https://en.wikipedia.org/wiki/Spring_1945_offensive_in_Italy\">pushed forward in Italy</a> and swept across western Germany capturing <a href=\"https://en.wikipedia.org/wiki/Battle_of_Hamburg_(1945)\">Hamburg</a> and <a href=\"https://en.wikipedia.org/wiki/Battle_of_Nuremberg_(1945)\">Nuremberg</a>. <a href=\"https://en.wikipedia.org/wiki/Elbe_Day\">American and Soviet forces met at the Elbe river</a> on 25 April, leaving several unoccupied pockets in southern Germany and around Berlin.</p>\n<p>Soviet and Polish forces <a href=\"https://en.wikipedia.org/wiki/Battle_of_Berlin\">stormed and captured Berlin</a> in late April. In Italy, <a href=\"https://en.wikipedia.org/wiki/Surrender_of_Caserta\">German forces surrendered</a> on 29 April. On 30 April, the <a href=\"https://en.wikipedia.org/wiki/Reichstag_building\">Reichstag</a> was captured, signalling the military defeat of Nazi Germany, Berlin garrison surrendered on 2 May.</p>\n<p>Several changes in leadership occurred during this period. On 12 April, President Roosevelt died and was succeeded by <a href=\"https://en.wikipedia.org/wiki/Harry_S._Truman\">Harry S. Truman</a>. Benito Mussolini <a href=\"https://en.wikipedia.org/wiki/Death_of_Benito_Mussolini\">was killed</a> by <a href=\"https://en.wikipedia.org/wiki/Italian_resistance_movement\">Italian partisans</a> on 28 April. Two days later, <a href=\"https://en.wikipedia.org/wiki/Death_of_Adolf_Hitler\">Hitler committed suicide</a> in besieged Berlin, and he was succeeded by <a href=\"https://en.wikipedia.org/wiki/Grand_Admiral\">Grand Admiral</a> <a href=\"https://en.wikipedia.org/wiki/Karl_D%C3%B6nitz\">Karl D&#246;nitz</a>.</p>\n<p><a href=\"https://en.wikipedia.org/wiki/German_Instrument_of_Surrender\">Total and unconditional surrender</a> in Europe was signed <a href=\"https://en.wikipedia.org/wiki/Victory_in_Europe_Day\">on 7 and 8 May</a>, to be effective by the end of <a href=\"https://en.wikipedia.org/wiki/Victory_Day_(Eastern_Front)\">8 May</a>. German Army Group Centre <a href=\"https://en.wikipedia.org/wiki/Prague_Offensive\">resisted in Prague</a> until 11 May.</p>\n<p>In the Pacific theatre, American forces accompanied by the forces of the <a href=\"https://en.wikipedia.org/wiki/Philippine_Commonwealth\">Philippine Commonwealth</a> advanced <a href=\"https://en.wikipedia.org/wiki/Philippines_Campaign_(1944%E2%80%931945)\">in the Philippines</a>, <a href=\"https://en.wikipedia.org/wiki/Battle_of_Leyte\">clearing Leyte</a> by the end of April 1945. They <a href=\"https://en.wikipedia.org/wiki/Battle_of_Luzon\">landed on Luzon</a> in January 1945 and <a href=\"https://en.wikipedia.org/wiki/Battle_of_Manila_(1945)\">recaptured Manila</a> in March. Fighting continued on Luzon, <a href=\"https://en.wikipedia.org/wiki/Battle_of_Mindanao\">Mindanao</a>, and other islands of the Philippines until the <a href=\"https://en.wikipedia.org/wiki/End_of_World_War_II_in_Asia\">end of the war</a>. Meanwhile, the <a href=\"https://en.wikipedia.org/wiki/United_States_Army_Air_Forces\">United States Army Air Forces</a> launched <a href=\"https://en.wikipedia.org/wiki/Air_raids_on_Japan\">a massive firebombing campaign</a> of strategic cities in Japan in an effort to destroy Japanese war industry and civilian morale. A devastating <a href=\"https://en.wikipedia.org/wiki/Bombing_of_Tokyo\">bombing raid on Tokyo of 9-10 March</a> was the deadliest conventional bombing raid in history.</p>\n<p><a href=\"https://en.wikipedia.org/wiki/File:Shigemitsu-signs-surrender.jpg\"><img src=\"https://upload.wikimedia.org/wikipedia/commons/thumb/e/e5/Shigemitsu-signs-surrender.jpg/220px-Shigemitsu-signs-surrender.jpg\"></a> </p>\n<p>In May 1945, Australian troops <a href=\"https://en.wikipedia.org/wiki/Borneo_campaign_(1945)\">landed in Borneo</a>, over-running the oilfields there. British, American, and Chinese forces defeated the Japanese in northern <a href=\"https://en.wikipedia.org/wiki/Burma_Campaign\">Burma</a> in March, and the British pushed on to reach <a href=\"https://en.wikipedia.org/wiki/Rangoon\">Rangoon</a> by 3 May. Chinese forces started a counterattack in the <a href=\"https://en.wikipedia.org/wiki/Battle_of_West_Hunan\">Battle of West Hunan</a> that occurred between 6 April and 7 June 1945. American naval and amphibious forces also moved towards Japan, taking <a href=\"https://en.wikipedia.org/wiki/Battle_of_Iwo_Jima\">Iwo Jima</a> by March, and <a href=\"https://en.wikipedia.org/wiki/Battle_of_Okinawa\">Okinawa</a> by the end of June. At the same time, American submarines <a href=\"https://en.wikipedia.org/wiki/Allied_submarines_in_the_Pacific_War\">cut off</a> Japanese imports, drastically reducing Japan's ability to supply its overseas forces.</p>\n<p>On 11 July, Allied leaders <a href=\"https://en.wikipedia.org/wiki/Potsdam_Conference\">met in Potsdam, Germany</a>. They <a href=\"https://en.wikipedia.org/wiki/Potsdam_Agreement\">confirmed earlier agreements</a> about Germany, and the American, British and Chinese governments reiterated the demand for unconditional surrender of Japan, specifically stating that <a href=\"https://en.wikipedia.org/wiki/Potsdam_Declaration\">\"the alternative for Japan is prompt and utter destruction\"</a>. During this conference, the United Kingdom <a href=\"https://en.wikipedia.org/wiki/1945_United_Kingdom_general_election\">held its general election</a>, and <a href=\"https://en.wikipedia.org/wiki/Clement_Attlee\">Clement Attlee</a> replaced Churchill as Prime Minister.</p>\n<p>The call for unconditional surrender was rejected by the Japanese government, which believed it would be capable of negotiating for more favourable surrender terms. In early August, the United States <a href=\"https://en.wikipedia.org/wiki/Atomic_bombings_of_Hiroshima_and_Nagasaki\">dropped atomic bombs</a> on the Japanese cities of <a href=\"https://en.wikipedia.org/wiki/Hiroshima\">Hiroshima</a> and <a href=\"https://en.wikipedia.org/wiki/Nagasaki\">Nagasaki</a>. Between the two bombings, the Soviets, pursuant to the Yalta agreement, <a href=\"https://en.wikipedia.org/wiki/Soviet_invasion_of_Manchuria\">invaded Japanese-held Manchuria</a> and quickly defeated the <a href=\"https://en.wikipedia.org/wiki/Kwantung_Army\">Kwantung Army</a>, which was the largest Japanese fighting force, thereby persuading previously adamant Imperial Army leaders to accept surrender terms. The Red Army also captured the southern part of <a href=\"https://en.wikipedia.org/wiki/Sakhalin\">Sakhalin</a> Island and the <a href=\"https://en.wikipedia.org/wiki/Kuril_Islands\">Kuril Islands</a>. On 15 August 1945, <a href=\"https://en.wikipedia.org/wiki/Surrender_of_Japan\">Japan surrendered</a>, with the <a href=\"https://en.wikipedia.org/wiki/Japanese_Instrument_of_Surrender\">surrender documents</a> finally signed at <a href=\"https://en.wikipedia.org/wiki/Tokyo_Bay\">Tokyo Bay</a> on the deck of the American battleship <a href=\"https://en.wikipedia.org/wiki/USS_Missouri_(BB-63)\">USS <i>Missouri</i></a> on 2 September 1945, ending the war.</p>\n<p>The Allies established occupation administrations in <a href=\"https://en.wikipedia.org/wiki/Allied-occupied_Austria\">Austria</a> and <a href=\"https://en.wikipedia.org/wiki/Allied-occupied_Germany\">Germany</a>. The former became a neutral state, non-aligned with any political bloc. The latter was divided into western and eastern occupation zones controlled by the Western Allies and the Soviet Union. A <a href=\"https://en.wikipedia.org/wiki/Denazification\">denazification</a> programme in Germany led to the prosecution of Nazi war criminals in the <a href=\"https://en.wikipedia.org/wiki/Nuremberg_trials\">Nuremberg trials</a> and the removal of ex-Nazis from power, although this policy moved towards amnesty and re-integration of ex-Nazis into West German society.</p>\n<p>Germany lost a quarter of its pre-war (1937) territory. Among the eastern territories, <a href=\"https://en.wikipedia.org/wiki/Silesia\">Silesia</a>, <a href=\"https://en.wikipedia.org/wiki/Neumark\">Neumark</a> and most of <a href=\"https://en.wikipedia.org/wiki/Pomerania\">Pomerania</a> were taken over by Poland, and <a href=\"https://en.wikipedia.org/wiki/East_Prussia\">East Prussia</a> was divided between Poland and the Soviet Union, followed by the <a href=\"https://en.wikipedia.org/wiki/Flight_and_expulsion_of_Germans_(1944%E2%80%9350)\">expulsion to Germany</a> of the nine million Germans from these provinces, as well as three million Germans from the <a href=\"https://en.wikipedia.org/wiki/Sudetenland\">Sudetenland</a> in Czechoslovakia. By the 1950s, one-fifth of West Germans were refugees from the east. The Soviet Union also took over the Polish provinces east of the <a href=\"https://en.wikipedia.org/wiki/Curzon_line\">Curzon line</a>, from which <a href=\"https://en.wikipedia.org/wiki/Polish_population_transfers_(1944%E2%80%931946)\">2 million Poles were expelled</a>; north-east Romania, parts of eastern Finland, and the three <a href=\"https://en.wikipedia.org/wiki/Baltic_states\">Baltic states</a> were <a href=\"https://en.wikipedia.org/wiki/Soviet_occupation_of_the_Baltic_states_(1944)\">incorporated into the Soviet Union</a>.</p>\n<p>In an effort to maintain <a href=\"https://en.wikipedia.org/wiki/World_peace\">world peace</a>, the Allies formed the <a href=\"https://en.wikipedia.org/wiki/United_Nations\">United Nations</a>, which officially came into existence on 24 October 1945, and adopted the <a href=\"https://en.wikipedia.org/wiki/Universal_Declaration_of_Human_Rights\">Universal Declaration of Human Rights</a> in 1948 as a common standard for all <a href=\"https://en.wikipedia.org/wiki/Member_states_of_the_United_Nations\">member nations</a>. The great powers that were the victors of the war-France, China, the United Kingdom, the Soviet Union and the United States-became the <a href=\"https://en.wikipedia.org/wiki/Permanent_members_of_the_United_Nations_Security_Council\">permanent members</a> of the UN's <a href=\"https://en.wikipedia.org/wiki/United_Nations_Security_Council\">Security Council</a>. The five permanent members remain so to the present, although there have been two seat changes, <a href=\"https://en.wikipedia.org/wiki/United_Nations_General_Assembly_Resolution_2758\">between</a> the <a href=\"https://en.wikipedia.org/wiki/Taiwan\">Republic of China</a> and the <a href=\"https://en.wikipedia.org/wiki/China\">People's Republic of China</a> in 1971, and between the Soviet Union and its <a href=\"https://en.wikipedia.org/wiki/Successor_state\">successor state</a>, the <a href=\"https://en.wikipedia.org/wiki/Russia\">Russian Federation</a>, following the <a href=\"https://en.wikipedia.org/wiki/Dissolution_of_the_Soviet_Union\">dissolution of the Soviet Union</a> in 1991. The alliance between the Western Allies and the Soviet Union had begun to deteriorate even before the war was over.</p>\n<p>Germany had been <i>de facto</i> divided, and two independent states, the <a href=\"https://en.wikipedia.org/wiki/West_Germany\">Federal Republic of Germany</a> and the <a href=\"https://en.wikipedia.org/wiki/East_Germany\">German Democratic Republic</a>, were created within the borders of <a href=\"https://en.wikipedia.org/wiki/Bizone\">Allied</a> and <a href=\"https://en.wikipedia.org/wiki/Soviet_occupation_zone\">Soviet occupation zones</a>. The rest of Europe was also divided into Western and Soviet <a href=\"https://en.wikipedia.org/wiki/Spheres_of_influence\">spheres of influence</a>. Most eastern and central European countries fell into <a href=\"https://en.wikipedia.org/wiki/Eastern_Bloc\">the Soviet sphere</a>, which led to establishment of Communist-led regimes, with full or partial support of the Soviet occupation authorities. As a result, <a href=\"https://en.wikipedia.org/wiki/East_Germany\">East Germany</a>, <a href=\"https://en.wikipedia.org/wiki/Polish_People%27s_Republic\">Poland</a>, <a href=\"https://en.wikipedia.org/wiki/Hungarian_People%27s_Republic\">Hungary</a>, <a href=\"https://en.wikipedia.org/wiki/Socialist_Republic_of_Romania\">Romania</a>, <a href=\"https://en.wikipedia.org/wiki/Czechoslovak_Socialist_Republic\">Czechoslovakia</a>, and <a href=\"https://en.wikipedia.org/wiki/People%27s_Socialist_Republic_of_Albania\">Albania</a> became Soviet <a href=\"https://en.wikipedia.org/wiki/Satellite_state\">satellite states</a>. Communist <a href=\"https://en.wikipedia.org/wiki/Socialist_Federal_Republic_of_Yugoslavia\">Yugoslavia</a> conducted a fully <a href=\"https://en.wikipedia.org/wiki/Non-Aligned_Movement\">independent policy</a>, causing <a href=\"https://en.wikipedia.org/wiki/Tito%E2%80%93Stalin_Split\">tension with the Soviet Union</a>.</p>\n<p>Post-war division of the world was formalised by two international military alliances, the United States-led <a href=\"https://en.wikipedia.org/wiki/NATO\">NATO</a> and the Soviet-led <a href=\"https://en.wikipedia.org/wiki/Warsaw_Pact\">Warsaw Pact</a>. The long period of political tensions and military competition between them, the <a href=\"https://en.wikipedia.org/wiki/Cold_War\">Cold War</a>, would be accompanied by an unprecedented <a href=\"https://en.wikipedia.org/wiki/Arms_race\">arms race</a> and <a href=\"https://en.wikipedia.org/wiki/Proxy_war\">proxy wars</a>.</p>\n<p>In Asia, the United States led the <a href=\"https://en.wikipedia.org/wiki/Occupation_of_Japan\">occupation of Japan</a> and <a href=\"https://en.wikipedia.org/wiki/Trust_Territory_of_the_Pacific_Islands\">administrated Japan's former islands</a> in the Western Pacific, while the Soviets annexed <a href=\"https://en.wikipedia.org/wiki/Sakhalin\">Sakhalin</a> and the <a href=\"https://en.wikipedia.org/wiki/Kuril_Islands\">Kuril Islands</a>. <a href=\"https://en.wikipedia.org/wiki/Korea\">Korea</a>, formerly <a href=\"https://en.wikipedia.org/wiki/Korea_under_Japanese_rule\">under Japanese rule</a>, was <a href=\"https://en.wikipedia.org/wiki/Division_of_Korea\">divided and occupied</a> by the Soviet Union in the <a href=\"https://en.wikipedia.org/wiki/North_Korea\">North</a> and the United States in the <a href=\"https://en.wikipedia.org/wiki/South_Korea\">South</a> between 1945 and 1948. Separate republics emerged on both sides of the 38th parallel in 1948, each claiming to be the legitimate government for all of Korea, which led ultimately to the <a href=\"https://en.wikipedia.org/wiki/Korean_War\">Korean War</a>.</p>\n<p>In China, nationalist and communist forces resumed <a href=\"https://en.wikipedia.org/wiki/Chinese_Civil_War\">the civil war</a> in June 1946. Communist forces were victorious and established the People's Republic of China on the mainland, while nationalist forces retreated to <a href=\"https://en.wikipedia.org/wiki/Taiwan\">Taiwan</a> in 1949. In the Middle East, the Arab rejection of the <a href=\"https://en.wikipedia.org/wiki/United_Nations_Partition_Plan_for_Palestine\">United Nations Partition Plan for Palestine</a> and the <a href=\"https://en.wikipedia.org/wiki/Creation_of_Israel\">creation of Israel</a> marked the escalation of the <a href=\"https://en.wikipedia.org/wiki/Arab%E2%80%93Israeli_conflict\">Arab-Israeli conflict</a>. While European powers attempted to retain some or all of their <a href=\"https://en.wikipedia.org/wiki/Colonial_empire\">colonial empires</a>, their losses of prestige and resources during the war rendered this unsuccessful, leading to <a href=\"https://en.wikipedia.org/wiki/Decolonization\">decolonisation</a>.</p>\n<p>The global economy suffered heavily from the war, although participating nations were affected differently. The United States emerged much richer than any other nation, leading to a <a href=\"https://en.wikipedia.org/wiki/Post%E2%80%93World_War_II_baby_boom\">baby boom</a>, and by 1950 its gross domestic product per person was much higher than that of any of the other powers, and it dominated the world economy. The UK and US pursued a policy of <a href=\"https://en.wikipedia.org/wiki/Allied_plans_for_German_industry_after_World_War_II\">industrial disarmament in Western Germany</a> in the years 1945-1948. Because of international trade interdependencies this led to European economic stagnation and delayed European recovery for several years.</p>\n<p>Recovery began with the mid-1948 <a href=\"https://en.wikipedia.org/wiki/Deutsche_Mark\">currency reform in Western Germany</a>, and was sped up by the liberalisation of European economic policy that the <a href=\"https://en.wikipedia.org/wiki/Marshall_Plan\">Marshall Plan</a> (1948-1951) both directly and indirectly caused. The post-1948 West German recovery has been called the <a href=\"https://en.wikipedia.org/wiki/Wirtschaftswunder#West_Germany\">German economic miracle</a>. Italy also experienced an <a href=\"https://en.wikipedia.org/wiki/Italian_economic_miracle\">economic boom</a> and the <a href=\"https://en.wikipedia.org/wiki/Trente_Glorieuses\">French economy rebounded</a>. By contrast, the United Kingdom was in a state of economic ruin, and although receiving a quarter of the total Marshall Plan assistance, more than any other European country, it continued in relative economic decline for decades.</p>\n<p>The Soviet Union, despite enormous human and material losses, also experienced rapid increase in production in the immediate post-war era. Japan experienced <a href=\"https://en.wikipedia.org/wiki/Japanese_post-war_economic_miracle\">incredibly rapid</a> economic growth, becoming one of the most powerful economies in the world by the 1980s. China returned to its pre-war industrial production by 1952.</p>\n<h3>Casualties and war crimes </h3>\n<p><a href=\"https://en.wikipedia.org/wiki/File:World_War_II_Casualties2.svg\"><img src=\"https://upload.wikimedia.org/wikipedia/commons/thumb/f/f1/World_War_II_Casualties2.svg/400px-World_War_II_Casualties2.svg.png\"></a> </p>\n<p>Estimates for the total number of casualties in the war vary, because many deaths went unrecorded. Most suggest that some 60 million people died in the war, including about <a href=\"https://en.wikipedia.org/wiki/Battle_casualties_of_World_War_II\">20 million military personnel</a> and 40 million civilians. Many of the civilians died because of deliberate <a href=\"https://en.wikipedia.org/wiki/Genocide\">genocide</a>, <a href=\"https://en.wikipedia.org/wiki/List_of_massacres\">massacres</a>, <a href=\"https://en.wikipedia.org/wiki/Strategic_bombing_during_World_War_II\">mass-bombings</a>, <a href=\"https://en.wikipedia.org/wiki/Infectious_disease\">disease</a>, and <a href=\"https://en.wikipedia.org/wiki/Starvation\">starvation</a>.</p>\n<p>The Soviet Union lost around 27 million people during the war, 8.7 million military and 19 million civilian deaths. A quarter of the people in the Soviet Union were wounded or killed. Germany sustained 5.3 million military losses, mostly on the Eastern Front and during the final battles in Germany.</p>\n<p>Of the total number of deaths in World War II, approximately 85 per cent-mostly Soviet and Chinese-were on the Allied side. Many of these deaths were caused by war crimes <a href=\"https://en.wikipedia.org/wiki/War_crimes_of_the_Wehrmacht\">committed by German</a> and <a href=\"https://en.wikipedia.org/wiki/Japanese_war_crimes\">Japanese forces</a> in occupied territories. An estimated 11 to 17 million civilians died as a direct or as an indirect result of Nazi racist policies, including <a href=\"https://en.wikipedia.org/wiki/Mass_killing\">mass killing</a> of <a href=\"https://en.wikipedia.org/wiki/The_Holocaust\">around 6 million Jews</a>, along with <a href=\"https://en.wikipedia.org/wiki/Romani_people\">Roma</a>, <a href=\"https://en.wikipedia.org/wiki/Persecution_of_homosexuals_in_Nazi_Germany_and_the_Holocaust\">homosexuals</a>, at least 1.9 million ethnic Poles and millions of other Slavs (including Russians, Ukrainians and Belarusians), and other ethnic and minority groups. Between 1941 and 1945, over 200,000 ethnic <a href=\"https://en.wikipedia.org/wiki/Serbs\">Serbs</a>, along with gypsies and Jews, were <a href=\"https://en.wikipedia.org/wiki/Persecution_of_Serbs_in_the_Independent_State_of_Croatia\">persecuted and murdered</a> by the Axis-aligned Croatian <a href=\"https://en.wikipedia.org/wiki/Usta%C5%A1e\">Usta&#353;e</a> in <a href=\"https://en.wikipedia.org/wiki/Yugoslavia\">Yugoslavia</a>. Also, over 100,000 Poles were massacred by the <a href=\"https://en.wikipedia.org/wiki/Ukrainian_Insurgent_Army\">Ukrainian Insurgent Army</a> in the <a href=\"https://en.wikipedia.org/wiki/Massacres_of_Poles_in_Volhynia_and_Eastern_Galicia\">Volhynia massacres</a>, between 1943 and 1945. At the same time about 10,000-15,000 Ukrainians were killed by the Polish <a href=\"https://en.wikipedia.org/wiki/Home_Army\">Home Army</a> and other Polish units, in reprisal attacks.</p>\n<p>In Asia and the Pacific, between 3 million and more than 10 million civilians, mostly Chinese (estimated at 7.5 million), were killed by the Japanese occupation forces. The most infamous Japanese atrocity was the <a href=\"https://en.wikipedia.org/wiki/Nanking_Massacre\">Nanking Massacre</a>, in which fifty to three hundred thousand Chinese civilians were raped and murdered. Mitsuyoshi Himeta reported that 2.7 million casualties occurred during the <i><a href=\"https://en.wikipedia.org/wiki/Three_Alls_Policy\">Sank&#333; Sakusen</a></i>.

The <a href=\"https://en.wikipedia.org/wiki/Imperial_Japanese_Army\">Imperial Japanese Army</a> used a variety of such weapons during its <a href=\"https://en.wikipedia.org/wiki/Second_Sino-Japanese_War\">invasion and occupation of China</a> ( <i>see <a href=\"https://en.wikipedia.org/wiki/Unit_731\">Unit 731</a></i>) and in <a href=\"https://en.wikipedia.org/wiki/Battles_of_Khalkhin_Gol\">early conflicts against the Soviets</a>. Both the Germans and <a href=\"https://en.wikipedia.org/wiki/Japanese_human_experimentation_on_the_Chinese\">Japanese tested</a> such weapons against civilians, and sometimes on <a href=\"https://en.wikipedia.org/wiki/Prisoner_of_war\">prisoners of war</a>.</p>\n<p>The Soviet Union was responsible for the <a href=\"https://en.wikipedia.org/wiki/Katyn_massacre\">Katyn massacre</a> of 22,000 Polish officers, and the imprisonment or execution of thousands of political prisoners by the <a href=\"https://en.wikipedia.org/wiki/NKVD\">NKVD</a>, along with <a href=\"https://en.wikipedia.org/wiki/Population_transfer_in_the_Soviet_Union\">mass civilian deportations to Siberia</a>, in the <a href=\"https://en.wikipedia.org/wiki/Occupation_of_the_Baltic_states\">Baltic states</a> and <a href=\"https://en.wikipedia.org/wiki/Territories_of_Poland_annexed_by_the_Soviet_Union\">eastern Poland</a> annexed by the Red Army.</p>\n<p>The <a href=\"https://en.wikipedia.org/wiki/Strategic_bombing_during_World_War_II\">mass-bombing of cities in Europe and Asia</a> has often been called a war crime, although no <a href=\"https://en.wikipedia.org/wiki/Positive_international_law\">positive</a> or specific <a href=\"https://en.wikipedia.org/wiki/Customary_international_law\">customary</a> <a href=\"https://en.wikipedia.org/wiki/International_humanitarian_law\">international humanitarian law</a> with respect to <a href=\"https://en.wikipedia.org/wiki/Aerial_warfare\">aerial warfare</a> existed before or during World War II. The USAAF <a href=\"https://en.wikipedia.org/wiki/Air_raids_on_Japan\">firebombed a total of 67 Japanese cities</a>, killing 393,000 civilians and destroying 65% of built-up areas.</p>\n<h3>Genocide, concentration camps, and slave labour </h3>\n<p><a href=\"https://en.wikipedia.org/wiki/Nazi_Germany\">Nazi Germany</a> was responsible for <a href=\"https://en.wikipedia.org/wiki/The_Holocaust\">the Holocaust</a> (killing approximately 6 million Jews), as well as for killing 2.7 million ethnic <a href=\"https://en.wikipedia.org/wiki/Nazi_crimes_against_the_Polish_nation\">Poles</a> and 4 million others who were deemed \" <a href=\"https://en.wikipedia.org/wiki/Life_unworthy_of_life\">unworthy of life</a>\" (including the <a href=\"https://en.wikipedia.org/wiki/Disability\">disabled</a> and <a href=\"https://en.wikipedia.org/wiki/Mental_disorder\">mentally ill</a>, <a href=\"https://en.wikipedia.org/wiki/German_mistreatment_of_Soviet_prisoners_of_war\">Soviet prisoners of war</a>, <a href=\"https://en.wikipedia.org/wiki/Romani_people\">Romani</a>, <a href=\"https://en.wikipedia.org/wiki/Homosexuals\">homosexuals</a>, <a href=\"https://en.wikipedia.org/wiki/Freemasons\">Freemasons</a>, and <a href=\"https://en.wikipedia.org/wiki/Jehovah%27s_Witnesses\">Jehovah's Witnesses</a>) as part of a programme of deliberate extermination, in effect becoming a \"genocidal state\". <a href=\"https://en.wikipedia.org/wiki/German_mistreatment_of_Soviet_prisoners_of_war\">Soviet POWs</a> were kept in especially unbearable conditions, and 3.6 million Soviet POWs out of 5.7 died in Nazi camps during the war. In addition to <a href=\"https://en.wikipedia.org/wiki/Nazi_concentration_camps\">concentration camps</a>, <a href=\"https://en.wikipedia.org/wiki/Extermination_camp\">death camps</a> were created in Nazi Germany to exterminate people at an industrial scale. Nazi Germany extensively used <a href=\"https://en.wikipedia.org/wiki/Forced_labour_under_German_rule_during_World_War_II\">forced labourers</a>; about 12 million <a href=\"https://en.wikipedia.org/wiki/Ostarbeiter\">Europeans</a> from German occupied countries were abducted and used as a slave work force in German industry, agriculture and war economy.</p>\n<p>The Soviet <a href=\"https://en.wikipedia.org/wiki/Gulag\">Gulag</a> became a <i>de facto</i> system of deadly camps during 1942-43, when wartime privation and hunger caused numerous deaths of inmates, including foreign citizens of Poland and <a href=\"https://en.wikipedia.org/wiki/Occupation_of_Baltic_States\">other countries</a> occupied in 1939-40 by the Soviet Union, as well as Axis <a href=\"https://en.wikipedia.org/wiki/German_prisoners_of_war_in_the_Soviet_Union\">POWs</a>. By the end of the war, most Soviet POWs liberated from Nazi camps and many repatriated civilians were detained in special filtration camps where they were subjected to <a href=\"https://en.wikipedia.org/wiki/NKVD\">NKVD</a> evaluation, and 226,127 were sent to the Gulag as real or perceived Nazi collaborators.</p>\n<p>Japanese <a href=\"https://en.wikipedia.org/wiki/Prisoner-of-war_camp\">prisoner-of-war camps</a>, many of which were used as labour camps, also had high death rates. The <a href=\"https://en.wikipedia.org/wiki/International_Military_Tribunal_for_the_Far_East\">International Military Tribunal for the Far East</a> found the death rate of Western prisoners was 27.1 per cent (for American POWs, 37 per cent), seven times that of POWs under the Germans and Italians. While 37,583 prisoners from the UK, 28,500 from the Netherlands, and 14,473 from the United States were released after the <a href=\"https://en.wikipedia.org/wiki/Surrender_of_Japan\">surrender of Japan</a>, the number of Chinese released was only 56.</p>\n<p>At least five million Chinese civilians from northern China and Manchukuo were enslaved between 1935 and 1941 by the <a href=\"https://en.wikipedia.org/wiki/East_Asia_Development_Board\">East Asia Development Board</a>, or <i>K&#333;ain</i>, for work in mines and war industries. After 1942, the number reached 10 million. In <a href=\"https://en.wikipedia.org/wiki/Java\">Java</a>, between 4 and 10 million (Japanese: \"manual labourers\"), were forced to work by the Japanese military. About 270,000 of these Javanese labourers were sent to other Japanese-held areas in South East Asia, and only 52,000 were repatriated to Java.</p>\n<h3>Occupation </h3>\n<p>In Europe, occupation came under two forms. In Western, Northern, and Central Europe (France, Norway, Denmark, the Low Countries, and the <a href=\"https://en.wikipedia.org/wiki/Protectorate_of_Bohemia_and_Moravia\">annexed portions of Czechoslovakia</a>) Germany established economic policies through which it collected roughly 69.5 billion reichmarks (27.8 billion US dollars) by the end of the war; this figure does not include the <a href=\"https://en.wikipedia.org/wiki/Nazi_plunder\">sizeable plunder</a> of industrial products, military equipment, raw materials and other goods. Thus, the income from occupied nations was over 40 per cent of the income Germany collected from taxation, a figure which increased to nearly 40 per cent of total German income as the war went on.</p>\n<p>In the East, the intended gains of <i><a href=\"https://en.wikipedia.org/wiki/Lebensraum\">Lebensraum</a></i> were never attained as fluctuating front-lines and Soviet <a href=\"https://en.wikipedia.org/wiki/Scorched_earth\">scorched earth</a> policies denied resources to the German invaders. Unlike in the West, the <a href=\"https://en.wikipedia.org/wiki/Racial_policy_of_Nazi_Germany\">Nazi racial policy</a> encouraged extreme brutality against what it considered to be the \" <a href=\"https://en.wikipedia.org/wiki/Untermensch\">inferior people</a>\" of Slavic descent; most German advances were thus followed by <a href=\"https://en.wikipedia.org/wiki/Generalplan_Ost\">mass executions</a>. Although <a href=\"https://en.wikipedia.org/wiki/Resistance_during_World_War_II\">resistance groups</a> formed in most occupied territories, they did not significantly hamper German operations in either the East or the West until late 1943.</p>\n<p>In Asia, Japan termed nations under its occupation as being part of the <a href=\"https://en.wikipedia.org/wiki/Greater_East_Asia_Co-Prosperity_Sphere\">Greater East Asia Co-Prosperity Sphere</a>, essentially a Japanese <a href=\"https://en.wikipedia.org/wiki/Hegemony\">hegemony</a> which it claimed was for purposes of liberating colonised peoples. Although Japanese forces were originally welcomed as liberators from European domination in some territories, their excessive brutality turned local public opinion against them within weeks. During Japan's initial conquest it captured 4,000,000 barrels (640,000 m <sup>3</sup>) of oil (~5.5&#215;10 <sup>5</sup> tonnes) left behind by retreating Allied forces, and by 1943 was able to get production in the Dutch East Indies up to 50 million barrels (~6.8 <sup>6</sup> t), 76 per cent of its 1940 output rate.</p>\n<h3>Home fronts and production </h3>\n<p><a href=\"https://en.wikipedia.org/wiki/File:WorldWarII-GDP-Relations-Allies-Axis-simple.svg\"><img src=\"https://upload.wikimedia.org/wikipedia/commons/thumb/4/44/WorldWarII-GDP-Relations-Allies-Axis-simple.svg/330px-WorldWarII-GDP-Relations-Allies-Axis-simple.svg.png\"></a> </p>\n<p>In Europe, before the outbreak of the war, the Allies had significant advantages in both population and economics. In 1938, the Western Allies (United Kingdom, France, Poland and British Dominions) had a 30 per cent larger population and a 30 per cent higher gross domestic product than the European Axis powers (Germany and Italy); if colonies are included, it then gives the Allies more than a 5:1 advantage in population and nearly 2:1 advantage in GDP. In Asia at the same time, China had roughly six times the population of Japan, but only an 89 per cent higher GDP; this is reduced to three times the population and only a 38 per cent higher GDP if Japanese colonies are included.</p>\n<p>The United States provided about two-thirds of all the ordnance used by the Allies in terms of warships, transports, warplanes, artillery, tanks, trucks, and ammunition. Though the Allies' economic and population advantages were largely mitigated during the initial rapid blitzkrieg attacks of Germany and Japan, they became the decisive factor by 1942, after the United States and Soviet Union joined the Allies, as the war largely settled into one of <a href=\"https://en.wikipedia.org/wiki/Attrition_warfare\">attrition</a>. While the Allies' ability to out-produce the Axis is often attributed to the Allies having more access to natural resources, other factors, such as Germany and Japan's reluctance to employ women in the <a href=\"https://en.wikipedia.org/wiki/Labour_force\">labour force</a>, Allied <a href=\"https://en.wikipedia.org/wiki/Strategic_bombing_during_World_War_II\">strategic bombing</a>, and Germany's late shift to a <a href=\"https://en.wikipedia.org/wiki/War_economy\">war economy</a> contributed significantly. Additionally, neither Germany nor Japan planned to fight a protracted war, and were not equipped to do so. To improve their production, Germany and Japan used millions of <a href=\"https://en.wikipedia.org/wiki/Slave_labour\">slave labourers</a>; <a href=\"https://en.wikipedia.org/wiki/Forced_labour_under_German_rule_during_World_War_II\">Germany used</a> about 12 million people, mostly from Eastern Europe, while <a href=\"https://en.wikipedia.org/wiki/Slavery_in_Japan\">Japan used</a> more than 18 million people in Far East Asia.</p>\n<h3>Advances in technology and warfare </h3>\n<p>Aircraft were used for <a href=\"https://en.wikipedia.org/wiki/Reconnaissance_aircraft\">reconnaissance</a>, as <a href=\"https://en.wikipedia.org/wiki/Fighter_aircraft\">fighters</a>, <a href=\"https://en.wikipedia.org/wiki/Bomber\">bombers</a>, and <a href=\"https://en.wikipedia.org/wiki/Close_air_support\">ground-support</a>, and each role was advanced considerably. Innovation included <a href=\"https://en.wikipedia.org/wiki/Airlift\">airlift</a> (the capability to quickly move limited high-priority supplies, equipment, and personnel); and of <a href=\"https://en.wikipedia.org/wiki/Strategic_bombing\">strategic bombing</a> (the bombing of enemy industrial and population centres to destroy the enemy's ability to wage war). <a href=\"https://en.wikipedia.org/wiki/Anti-aircraft_warfare\">Anti-aircraft weaponry</a> also advanced, including defences such as <a href=\"https://en.wikipedia.org/wiki/Radar\">radar</a> and surface-to-air artillery. The use of the <a href=\"https://en.wikipedia.org/wiki/Jet_aircraft\">jet aircraft</a> was pioneered and, though late introduction meant it had little impact, it led to jets becoming standard in air forces worldwide. Although <a href=\"https://en.wikipedia.org/wiki/Missile\">guided missiles</a> were being developed, they were not advanced enough to reliably <a href=\"https://en.wikipedia.org/wiki/Surface-to-air_missile\">target aircraft</a> until some years after the war.</p>\n<p>Advances were made in nearly every aspect of <a href=\"https://en.wikipedia.org/wiki/Naval_warfare\">naval warfare</a>, most notably with <a href=\"https://en.wikipedia.org/wiki/Aircraft_carrier\">aircraft carriers</a> and <a href=\"https://en.wikipedia.org/wiki/Submarine\">submarines</a>. Although <a href=\"https://en.wikipedia.org/wiki/Aeronautics\">aeronautical</a> warfare had relatively little success at the start of the war, <a href=\"https://en.wikipedia.org/wiki/Battle_of_Taranto\">actions at Taranto</a>, <a href=\"https://en.wikipedia.org/wiki/Attack_on_Pearl_Harbor\">Pearl Harbor</a>, and the <a href=\"https://en.wikipedia.org/wiki/Battle_of_the_Coral_Sea\">Coral Sea</a> established the carrier as the dominant capital ship in place of the battleship. In the Atlantic, <a href=\"https://en.wikipedia.org/wiki/Escort_carrier\">escort carriers</a> proved to be a vital part of Allied convoys, increasing the effective protection radius and helping to close the <a href=\"https://en.wikipedia.org/wiki/Mid-Atlantic_gap\">Mid-Atlantic gap</a>. Carriers were also more economical than <a href=\"https://en.wikipedia.org/wiki/Battleship\">battleships</a> because of the relatively low cost of aircraft and their not requiring to be as heavily armoured. Submarines, which had proved to be an effective weapon during the <a href=\"https://en.wikipedia.org/wiki/World_War_I\">First World War</a>, were anticipated by all sides to be important in the second. The British focused development on <a href=\"https://en.wikipedia.org/wiki/Anti-submarine_warfare\">anti-submarine</a> <a href=\"https://en.wikipedia.org/wiki/Anti-submarine_weapon\">weaponry</a> and tactics, such as <a href=\"https://en.wikipedia.org/wiki/Sonar\">sonar</a> and convoys, while Germany focused on improving its offensive capability, with designs such as the <a href=\"https://en.wikipedia.org/wiki/German_Type_VII_submarine\">Type VII submarine</a> and <a href=\"https://en.wikipedia.org/wiki/Wolfpack_(naval_tactic)\">wolfpack</a> tactics. Gradually, improving Allied technologies such as the <a href=\"https://en.wikipedia.org/wiki/Leigh_light\">Leigh light</a>, <a href=\"https://en.wikipedia.org/wiki/Hedgehog_(weapon)\">hedgehog</a>, <a href=\"https://en.wikipedia.org/wiki/Squid_(weapon)\">squid</a>, and <a href=\"https://en.wikipedia.org/wiki/Mark_24_mine\">homing torpedoes</a> proved victorious over the German submarines.</p>\n<p><a href=\"https://en.wikipedia.org/wiki/Land_warfare\">Land warfare</a> changed from the static front lines of <a href=\"https://en.wikipedia.org/wiki/Trench_warfare\">trench warfare</a> of World War I, which had relied on improved <a href=\"https://en.wikipedia.org/wiki/Artillery\">artillery</a> that outmatched the speed of both <a href=\"https://en.wikipedia.org/wiki/Infantry\">infantry</a> and <a href=\"https://en.wikipedia.org/wiki/Cavalry\">cavalry</a>, to increased mobility and <a href=\"https://en.wikipedia.org/wiki/Combined_arms\">combined arms</a>. The <a href=\"https://en.wikipedia.org/wiki/Tank\">tank</a>, which had been used predominantly for infantry support in the First World War, had evolved into the primary weapon. In the late 1930s, tank design was considerably more advanced than it had been during World War I, and <a href=\"https://en.wikipedia.org/wiki/Tanks_in_World_War_II\">advances continued throughout the war</a> with increases in speed, armour and firepower. At the start of the war, most commanders thought enemy tanks should be met by tanks with superior specifications. This idea was challenged by the poor performance of the relatively light early tank guns against armour, and German doctrine of avoiding tank-versus-tank combat. This, along with Germany's use of combined arms, were among the key elements of their highly successful blitzkrieg tactics across Poland and France. Many means of <a href=\"https://en.wikipedia.org/wiki/Anti-tank_warfare\">destroying tanks</a>, including <a href=\"https://en.wikipedia.org/wiki/Indirect_fire\">indirect artillery</a>, <a href=\"https://en.wikipedia.org/wiki/Anti-tank_gun\">anti-tank guns</a> (both towed and <a href=\"https://en.wikipedia.org/wiki/Self-propelled_gun\">self-propelled</a>), <a href=\"https://en.wikipedia.org/wiki/Anti-tank_mine\">mines</a>, short-ranged infantry antitank weapons, and other tanks were used. Even with large-scale mechanisation, infantry remained the backbone of all forces, and throughout the war, most infantry were equipped similarly to World War I. The portable machine gun spread, a notable example being the German <a href=\"https://en.wikipedia.org/wiki/MG34\">MG34</a>, and various <a href=\"https://en.wikipedia.org/wiki/Submachine_gun\">submachine guns</a> which were suited to <a href=\"https://en.wikipedia.org/wiki/Close_combat\">close combat</a> in urban and jungle settings.
