During World War II, it has been estimated that between 19,500 and 50,000 members of the Imperial Japanese military surrendered to Western Allied combatants prior to the end of the Pacific War in August 1945.Soviet troops seized and imprisoned more than half a million Japanese troops and civilians in China and other places. The number of Japanese soldiers, sailors, marines, and airmen who surrendered was limited by the Japanese military indoctrinating its personnel to fight to the death, Allied combat personnel often being unwilling to take prisoners, and many Japanese soldiers believing that those who surrendered would be killed by their captors.
Western Allied governments and senior military commanders directed that Japanese POWs be treated in accordance with relevant international conventions. In practice though, many Allied soldiers were unwilling to accept the surrender of Japanese troops because of atrocities committed by the Japanese. A campaign launched in 1944 to encourage prisoner-taking was partially successful, and the number of prisoners taken increased significantly in the last year of the war.
Japanese POWs often believed that by surrendering they had broken all ties with Japan, and many provided military intelligence to the Allies. The prisoners taken by the Western Allies were held in generally good conditions in camps located in Australia, New Zealand, India and the United States. Those taken by the Soviet Union were treated harshly in work camps located in Siberia. Following the war the prisoners were repatriated to Japan, though the United States and Britain retained thousands until 1946 and 1947 respectively and the Soviet Union continued to hold as many as hundreds of thousands of Japanese POWs until the early 1950s. The Soviet Union gradually released some POWs throughout the next few decades, but some did not return until the collapse of the Soviet Union in the 1990s, while others who had settled and started families in the Soviet Union opted to remain.
During the 1920s and 1930s, the Imperial Japanese Army (IJA) adopted an ethos which required soldiers to fight to the death rather than surrender.This policy reflected the practices of Japanese warfare in the pre-modern era. During the Meiji period the Japanese government adopted western policies towards POWs, and few of the Japanese personnel who surrendered in the Russo-Japanese War were punished at the end of the war. Prisoners captured by Japanese forces during this and the First Sino-Japanese War and World War I were also treated in accordance with international standards. The relatively good treatment that prisoners in Japan received was used as a propaganda tool, exuding a sense of "chivalry" in comparison to the more barbaric perception of Asia that the Meiji government wished to avoid. Attitudes towards surrender hardened after World War I. While Japan signed the 1929 Geneva Convention covering treatment of POWs, it did not ratify the agreement, claiming that surrender was contrary to the beliefs of Japanese soldiers. This attitude was reinforced by the indoctrination of young people.
The Japanese military's attitude towards surrender was institutionalized in the 1941 "Code of Battlefield Conduct" ( Senjinkun ), which was issued to all Japanese soldiers. This document sought to establish standards of behavior for Japanese troops and improve discipline and morale within the Army, and included a prohibition against being taken prisoner.The Japanese Government accompanied the Senjinkun's implementation with a propaganda campaign which celebrated people who had fought to the death rather than surrender during Japan's wars. While the Imperial Japanese Navy (IJN) did not issue a document equivalent to the Senjinkun, naval personnel were expected to exhibit similar behavior and not surrender. Most Japanese military personnel were told that they would be killed or tortured by the Allies if they were taken prisoner. The Army's Field Service Regulations were also modified in 1940 to replace a provision which stated that seriously wounded personnel in field hospitals came under the protection of the 1929 Geneva Convention for the Sick and Wounded Armies in the Field with a requirement that the wounded not fall into enemy hands. During the war, this led to wounded personnel being either killed by medical officers or given grenades to commit suicide. Aircrew from Japanese aircraft which crashed over Allied-held territory also typically committed suicide rather than allow themselves to be captured.
While scholars disagree over whether the Senjinkun was legally binding on Japanese soldiers, the document reflected Japan's societal norms and had great force over both military personnel and civilians. In 1942 the Army amended its criminal code to specify that officers who surrendered soldiers under their command faced at least six months imprisonment, regardless of the circumstances in which the surrender took place. This change attracted little attention, however, as the Senjinkun imposed more severe consequences and had greater moral force.
The indoctrination of Japanese military personnel to have little respect for the act of surrendering led to conduct which Allied soldiers found deceptive. During the Pacific War, there were incidents where Japanese soldiers feigned surrender in order to lure Allied troops into ambushes. In addition, wounded Japanese soldiers sometimes tried to use hand grenades to kill Allied troops attempting to assist them.Japanese attitudes towards surrender also contributed to the harsh treatment which was inflicted on the Allied personnel they captured.
Not all Japanese military personnel chose to follow the precepts set out on the Senjinkun. Those who chose to surrender did so for a range of reasons including not believing that suicide was appropriate or lacking the will to commit the act, bitterness towards officers, and Allied propaganda promising good treatment.During the later years of the war Japanese troops' morale deteriorated as a result of Allied victories, leading to an increase in the number who were prepared to surrender or desert. During the Battle of Okinawa, 11,250 Japanese military personnel (including 3,581 unarmed labourers) surrendered between April and July 1945, representing 12 percent of the force deployed for the defense of the island. Many of these men were recently conscripted members of Boeitai home guard units who had not received the same indoctrination as regular Army personnel, but substantial numbers of IJA soldiers also surrendered.
Japanese soldiers' reluctance to surrender was also influenced by a perception that Allied forces would kill them if they did surrender, and historian Niall Ferguson has argued that this had a more important influence in discouraging surrenders than the fear of disciplinary action or dishonor.In addition, the Japanese public was aware that US troops sometimes mutilated Japanese casualties and sent trophies made out of body-parts home from media reports of two high-profile incidents in 1944 in which a letter-opener carved from a bone of a Japanese soldier was presented to President Roosevelt and a photo of the skull of a Japanese soldier which had been sent home by a US soldier was published in the magazine Life . In these reports Americans were portrayed as "deranged, primitive, racist and inhuman". Hoyt in "Japan’s war: the great Pacific conflict" argues that the Allied practice of taking bones from Japanese corpses home as souvenirs was exploited by Japanese propaganda very effectively, and "contributed to a preference to death over surrender and occupation, shown, for example, in the mass civilian suicides on Saipan and Okinawa after the Allied landings".
The causes of the phenomenon that Japanese often continued to fight even in hopeless situations has been traced to a combination of Shinto, Messhi hoko (self-sacrifice for the sake of group), and Bushido. However, a factor equally strong or even stronger to those, was the fear of torture after capture. This fear grew out of years of battle experiences in China, where the Chinese guerrillas were considered expert torturers, and this fear was projected onto the American soldiers who also were expected to torture and kill surrendered Japanese.During the Pacific War the majority of Japanese military personnel did not believe that the Allies treated prisoners correctly, and even a majority of those who surrendered expected to be killed.
The Western Allies sought to treat captured Japanese in accordance with international agreements which governed the treatment of POWs.Shortly after the outbreak of Pacific War in December 1941, the British and United States governments transmitted a message to the Japanese government through Swiss intermediaries asking if Japan would abide by the 1929 Geneva Convention. The Japanese Government responded stating that while it had not signed the convention, Japan would treat POWs in accordance with its terms; in effect though, Japan had willfully ignored the convention's requirements. While the Western Allies notified the Japanese government of the identities of Japanese POWs in accordance with the Geneva Convention's requirements, this information was not passed onto the families of the captured men as the Japanese government wished to maintain that none of its soldiers had been taken prisoner.
Allied combatants were reluctant to take Japanese prisoners at the start of the Pacific War. During the first two years following the US entry into the war, US combatants were generally unwilling to accept the surrender of Japanese soldiers due to a combination of racist attitudes and anger at Japan's war crimes committed against US and Allied nationals such as its widespread mistreatment or summary execution of Allied POWs.Australian soldiers were also reluctant to take Japanese prisoners for similar reasons. Incidents in which Japanese soldiers booby-trapped their dead and wounded or pretended to surrender in order to lure Allied combatants into ambushes were well known within the Allied militaries and also hardened attitudes against seeking the surrender of Japanese on the battlefield. As a result, Allied troops believed that their Japanese opponents would not surrender and that any attempts to surrender were deceptive; for instance, the Australian jungle warfare school advised soldiers to shoot any Japanese troops who had their hands closed while surrendering. Furthermore, in many instances, Japanese soldiers who had surrendered were killed on the front line or while being taken to POW compounds. The nature of jungle warfare also contributed to prisoners not being taken, as many battles were fought at close ranges where participants "often had no choice but to shoot first and ask questions later".
Despite the attitudes of combat troops and nature of the fighting, Allied militaries made systematic efforts to take Japanese prisoners throughout the war. Each US Army division was assigned a team of Japanese Americans whose duties included attempting to persuade Japanese personnel to surrender.Allied forces mounted an extensive psychological warfare campaign against their Japanese opponents to lower their morale and encourage surrender. This included dropping copies of the Geneva Conventions and 'surrender passes' on Japanese positions. This campaign was undermined by Allied troops' reluctance to take prisoners, however. As a result, from May 1944, senior US Army commanders authorized and endorsed educational programs which aimed to change the attitudes of front line troops. These programs highlighted the intelligence which could be gained from Japanese POWs, the need to honor surrender leaflets, and the benefits which could be gained by encouraging Japanese forces to not fight to the last man. The programs were partially successful, and contributed to US troops taking more prisoners. In addition, soldiers who witnessed Japanese troops surrender were more willing to take prisoners themselves.
Survivors of ships sunk by Allied submarines frequently refused to surrender, and many of the prisoners who were captured by submariners were taken by force. US Navy submarines were occasionally ordered to obtain prisoners for intelligence purposes, and formed special teams of personnel for this purpose.Overall, however, Allied submariners usually did not attempt to take prisoners, and the number of Japanese personnel they captured was relatively small. The submarines which took prisoners normally did so towards the end of their patrols so that they did not have to be guarded for a long time.
Allied forces continued to kill many Japanese personnel who were attempting to surrender throughout the war.It is likely that more Japanese soldiers would have surrendered if they had not believed that they would be killed by the Allies while trying to do so. Fear of being killed after surrendering was one of the main factors which influenced Japanese troops to fight to the death, and a wartime US Office of Wartime Information report stated that it may have been more important than fear of disgrace and a desire to die for Japan. Instances of Japanese personnel being killed while attempting to surrender are not well documented, though anecdotal accounts provide evidence that this occurred.
Estimates of the numbers of Japanese personnel taken prisoner during the Pacific War differ.Japanese historian Ikuhiko Hata states that up to 50,000 Japanese became POWs before Japan's surrender. The Japanese Government's wartime POW Information Bureau believed that 42,543 Japanese surrendered during the war; a figure also used by Niall Ferguson who states that it refers to prisoners taken by United States and Australian forces. Ulrich Straus states that about 35,000 were captured by western Allied and Chinese forces, and Robert C. Doyle gives a figure of 38,666 Japanese POWs in captivity in camps run by the western Allies at the end of the war. Alison B. Gilmore has also calculated that Allied forces in the South West Pacific Area alone captured at least 19,500 Japanese. a
As the Japanese forces in China were mainly on the offensive and suffered relatively few casualties, few Japanese soldiers surrendered to Chinese forces prior to August 1945.It has been estimated that at the end of the war Chinese Nationalist and Communist forces held around 8,300 Japanese prisoners. The conditions these POWs were held in generally did not meet the standards required by international law. The Japanese government expressed no concern for these abuses, however, as it did not want IJA soldiers to even consider surrendering. The government was, however, concerned about reports that 300 POWs had joined the Chinese Communists and had been trained to spread anti-Japanese propaganda.
The Japanese government sought to suppress information about captured personnel. On 27 December 1941, it established a POW Information Bureau within the Ministry of the Army to manage information concerning Japanese POWs. While the Bureau cataloged information provided by the Allies via the Red Cross identifying POWs, it did not pass this information on to the families of the prisoners. When individuals wrote to the Bureau to inquire if their relative had been taken prisoner, it appears that the Bureau provided a reply which neither confirmed or denied whether the man was a prisoner. Although the Bureau's role included facilitating mail between POWs and their families, this was not carried out as the families were not notified and few POWs wrote home. The lack of communication with their families increased the POWs feelings of being cut off from Japanese society.
The Allies gained considerable quantities of intelligence from Japanese POWs. Because they had been indoctrinated to believe that by surrendering they had broken all ties with Japan, many captured personnel provided their interrogators with information on the Japanese military.Australian and US troops and senior officers commonly believed that captured Japanese troops were very unlikely to divulge any information of military value, leading to them having little motivation to take prisoners. This view proved incorrect, however, and many Japanese POWs provided valuable intelligence during interrogations. Few Japanese were aware of the Geneva Convention and the rights it gave prisoners to not respond to questioning. Moreover, the POWs felt that by surrendering they had lost all their rights. The prisoners appreciated the opportunity to converse with Japanese-speaking Americans and felt that the food, clothing and medical treatment they were provided with meant that they owed favours to their captors. The Allied interrogators found that exaggerating the amount they knew about the Japanese forces and asking the POWs to 'confirm' details was also a successful approach. As a result of these factors, Japanese POWs were often cooperative and truthful during interrogation sessions.
Japanese POWs were interrogated multiple times during their captivity. Most Japanese soldiers were interrogated by intelligence officers of the battalion or regiment which had captured them for information which could be used by these units. Following this they were rapidly moved to rear areas where they were interrogated by successive echelons of the Allied military. They were also questioned once they reached a POW camp in Australia, New Zealand, India or the United States. These interrogations were painful and stressful for the POWs.Similarly, Japanese sailors rescued from sunken ships by the US Navy were questioned at the Navy's interrogation centres in Brisbane, Honolulu and Noumea. Allied interrogators found that Japanese soldiers were much more likely to provide useful intelligence than Imperial Japanese Navy personnel, possibly due to differences in the indoctrination provided to members of the services. Force was not used in interrogations at any level, though on one occasion headquarters personnel of the US 40th Infantry Division debated, but ultimately decided against, administering sodium penthanol to a senior non-commissioned officer.
Some Japanese POWs also played an important role in helping the Allied militaries develop propaganda and politically indoctrinate their fellow prisoners.This included developing propaganda leaflets and loudspeaker broadcasts which were designed to encourage other Japanese personnel to surrender. The wording of this material sought to overcome the indoctrination which Japanese soldiers had received by stating that they should "cease resistance" rather than "surrender". POWs also provided advice on the wording for propaganda leaflets which were dropped on Japanese cities by heavy bombers in the final months of the war.
Japanese POWs held in Allied prisoner of war camps were treated in accordance with the Geneva Convention.By 1943 the Allied governments were aware that personnel who had been captured by the Japanese military were being held in harsh conditions. In an attempt to win better treatment for their POWs, the Allies made extensive efforts to notify the Japanese government of the good conditions in Allied POW camps. This was not successful, however, as the Japanese government refused to recognise the existence of captured Japanese military personnel. Nevertheless, Japanese POWs in Allied camps continued to be treated in accordance with the Geneva Conventions until the end of the war.
Most Japanese captured by US forces after September 1942 were turned over to Australia or New Zealand for internment. The United States provided these countries with aid through the Lend Lease program to cover the costs of maintaining the prisoners, and retained responsibility for repatriating the men to Japan at the end of the war. Prisoners captured in the central Pacific or who were believed to have particular intelligence value were held in camps in the United States.
Prisoners who were thought to possess significant technical or strategic information were brought to specialist intelligence-gathering facilities at Fort Hunt, Virginia or Camp Tracy, California. After arriving in these camps, the prisoners were interrogated again, and their conversations were wiretapped and analysed. Some of the conditions at Camp Tracy violated Geneva Convention requirements, such as insufficient exercise time being provided. However, prisoners at this camp were given special benefits, such as high quality food and access to a shop, and the interrogation sessions were relatively relaxed. The continuous wiretapping at both locations may have also violated the spirit of the Geneva Convention.
Japanese POWs generally adjusted to life in prison camps and few attempted to escape.There were several incidents at POW camps, however. On 25 February 1943, POWs at the Featherston prisoner of war camp in New Zealand staged a strike after being ordered to work. The protest turned violent when the camp's deputy commander shot one of the protest's leaders. The POWs then attacked the other guards, who opened fire and killed 48 prisoners and wounded another 74. Conditions at the camp were subsequently improved, leading to good relations between the Japanese and their New Zealand guards for the remainder of the war. More seriously, on 5 August 1944, Japanese POWs in a camp near Cowra, Australia attempted to escape. During the fighting between the POWs and their guards 257 Japanese and four Australians were killed. Other confrontations between Japanese POWs and their guards occurred at Camp McCoy in Wisconsin during May 1944 as well as a camp in Bikaner, India during 1945; these did not result in any fatalities. In addition, 24 Japanese POWs killed themselves at Camp Paita, New Caledonia in January 1944 after a planned uprising was foiled. News of the incidents at Cowra and Featherston was suppressed in Japan, but the Japanese Government lodged protests with the Australian and New Zealand governments as a propaganda tactic. This was the only time that the Japanese Government officially recognized that some members of the country's military had surrendered.
The Allies distributed photographs of Japanese POWs in camps to induce other Japanese personnel to surrender. This tactic was initially rejected by General MacArthur when it was proposed to him in mid-1943 on the grounds that it violated the Hague and Geneva Conventions, and the fear of being identified after surrendering could harden Japanese resistance. MacArthur reversed his position in December of that year, however, but only allowed the publication of photos that did not identify individual POWs. He also directed that the photos "should be truthful and factual and not designed to exaggerate".
Millions of Japanese military personnel surrendered following the end of the war. Soviet and Chinese forces accepted the surrender of 1.6 million Japanese and the western allies took the surrender of millions more in Japan, South-East Asia and the South-West Pacific.In order to prevent resistance to the order to surrender, Japan's Imperial Headquarters included a statement that "servicemen who come under the control of enemy forces after the proclamation of the Imperial Rescript will not be regarded as POWs" in its orders announcing the end of the war. While this measure was successful in avoiding unrest, it led to hostility between those who surrendered before and after the end of the war and denied prisoners of the Soviets POW status. In most instances the troops who surrendered were not taken into captivity, and were repatriated to the Japanese home islands after giving up their weapons.
Repatriation of some Japanese POWs was delayed by Allied authorities. Until late 1946, the United States retained almost 70,000 POWs to dismantle military facilities in the Philippines, Okinawa, central Pacific, and Hawaii. British authorities retained 113,500 of the approximately 750,000 POWs in south and south-east Asia until 1947; the last POWs captured in Burma and Malaya returned to Japan in October 1947.The British also used armed Japanese Surrendered Personnel to support Dutch and French attempts to reestablish their colonial empires in the Netherlands East Indies and Indochina respectively. At least 81,090 Japanese personnel died in areas occupied by the western Allies and China before they could be repatriated to Japan. Historian John W. Dower has attributed these deaths to the "wretched" condition of Japanese military units at the end of the war.
Nationalist Chinese forces took the surrender of 1.2 million Japanese military personnel following the war. While the Japanese feared that they would be subjected to reprisals, they were generally treated well. This was because the Nationalists wished to seize as many weapons as possible, ensure that the departure of the Japanese military didn't create a security vacuum and discourage Japanese personnel from fighting alongside the Chinese communists.Over the next few months, most Japanese prisoners in China, along with Japanese civilian settlers, were returned to Japan. The nationalists retained over 50,000 POWs, most of whom had technical skills, until the second half of 1946, however. Tens of thousands of Japanese prisoners captured by the Chinese communists were serving in their military forces in August 1946 and more than 60,000 were believed to still be held in Communist-controlled areas as late as April 1949. Hundreds of Japanese POWs were killed fighting for the People's Liberation Army during the Chinese Civil War. Following the war, the victorious Chinese Communist government began repatriating Japanese prisoners home, though some were put on trial for war crimes and had to serve prison sentences of varying length before being allowed to return. The last Japanese prisoner returned from China in 1964.
Hundreds of thousands of Japanese also surrendered to Soviet forces in the last weeks of the war and after Japan's surrender. The Soviet Union claimed to have taken 594,000 Japanese POWs, of whom 70,880 were immediately released, but Japanese researchers have estimated that 850,000 were captured.Unlike the prisoners held by China or the western Allies, these men were treated harshly by their captors, and over 60,000 died. Japanese POWs were forced to undertake hard labour and were held in primitive conditions with inadequate food and medical treatments. This treatment was similar to that experienced by German POWs in the Soviet Union. The treatment of Japanese POWs in Siberia was also similar to that suffered by Soviet prisoners who were being held in the area. Between 1946 and 1950, many of the Japanese POWs in Soviet captivity were released; those remaining after 1950 were mainly those convicted of various crimes. They were gradually released under a series of amnesties between 1953 and 1956. After the last major repatriation in 1956, the Soviets continued to hold some POWs and release them in small increments. Some ended up spending decades living in the Soviet Union, and could only return to Japan in the 1990s. Some, having spent decades away and having started families of their own, elected not to permanently settle in Japan and remain where they were.
Due to the shame associated with surrendering, few Japanese POWs wrote memoirs after the war.
^a Gilmore provides the following numbers of Japanese POWs taken in the SWPA during each year of the war; 1942: 1,167, 1943: 1,064, 1944: 5,122, 1945: 12,194
A prisoner of war (POW) is a non-combatant—whether a military member, an irregular military fighter, or a civilian—who is held captive by a belligerent power during or immediately after an armed conflict. The earliest recorded usage of the phrase "prisoner of war" dates back to 1610.
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from more than 30 countries. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 70 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. Tens of millions of people died during the conflict due to genocides, premeditated death from starvation, massacres, and disease. Aircraft played a major role in the conflict which included the use of terror bombing, strategic bombing and the only use of nuclear weapons in war.
The Allied occupation of Japan at the end of World War II was led by General Douglas MacArthur, the Supreme Commander of the Allied Powers, with support from the British Commonwealth. Unlike in the occupation of Germany, the Soviet Union was allowed little to no influence over Japan. This foreign presence marks the only time in Japan's history that it has been occupied by a foreign power. At MacArthur's insistence, Emperor Hirohito remained on the imperial throne. The wartime cabinet was replaced with a cabinet acceptable to the Allies and committed to implementing the terms of the Potsdam Declaration, which among other things called for the country to become a parliamentary democracy. Under MacArthur's guidance, the Japanese government introduced sweeping social reforms and implemented economic reforms that recalled American "New Deal" priorities of the 1930s under President Roosevelt. The Japanese constitution was comprehensively overhauled and the Emperor's theoretically-vast powers, which for many centuries had been constrained by conventions that had evolved over time, became strictly limited by law. The occupation, codenamed Operation Blacklist, was ended by the San Francisco Peace Treaty, signed on September 8, 1951, and effective from April 28, 1952, after which Japan's sovereignty – with the exception, until 1972, of the Ryukyu Islands – was fully restored.
The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in the Pacific and Asia. It was geographically the largest theater of the war, including the vast Pacific Ocean theater, the South West Pacific theater, the South-East Asian theater, the Second Sino-Japanese War, and the Soviet–Japanese War.
The final battles of the European Theatre of World War II as well as the German surrender to the Allies took place in late April and early May 1945.
The Western Front was a military theatre of World War II encompassing Denmark, Norway, Luxembourg, Belgium, the Netherlands, the United Kingdom, France, Italy, and Germany. World War II military engagements in Southern Europe and elsewhere are generally considered under separate headings. The Western Front was marked by two phases of large-scale combat operations. The first phase saw the capitulation of the Netherlands, Belgium, and France during May and June 1940 after their defeat in the Low Countries and the northern half of France, and continued into an air war between Germany and Britain that climaxed with the Battle of Britain. The second phase consisted of large-scale ground combat, which began in June 1944 with the Allied landings in Normandy and continued until the defeat of Germany in May 1945.
Disarmed Enemy Forces was a US designation for soldiers who surrendered to an adversary after hostilities ended, and for those POWs who had already surrendered and were held in camps in occupied German territory at the time. It was Dwight D. Eisenhower's designation of German prisoners in post-World War II occupied Germany.
War crimes were committed by the Empire of Japan in many Asian-Pacific countries during the period of Japanese imperialism, primarily during the Second Sino-Japanese War and World War II. These incidents have been described as an "Asian Holocaust". Some war crimes were committed by Japanese military personnel during the late 19th century, but most Japanese war crimes were committed during the first part of the Shōwa Era, the name which was given to the reign of Emperor Hirohito, until the surrender of the Empire of Japan in 1945.
The Battle of Rabaul, also known by the Japanese as Operation R, was fought on the island of New Britain in the Australian Territory of New Guinea, in January and February 1942. It was a strategically significant defeat of Allied forces by Japan in the Pacific campaign of World War II, with the Japanese invasion force quickly overwhelming the small Australian garrison, the majority of which was either killed or captured. Hostilities on the neighbouring island of New Ireland are also usually considered to be part of the same battle. Rabaul was significant because of its proximity to the Japanese territory of the Caroline Islands, site of a major Imperial Japanese Navy base on Truk.
The end of World War II in Asia occurred on 2 September 1945, when armed forces of the Empire of Japan surrendered to the forces of the Allies. The surrender came almost four months after the surrender of the Axis forces in Europe and brought an end to World War II.
The Allies of World War II, called the United Nations from the 1 January 1942 declaration, were the countries that together opposed the Axis powers during the Second World War (1939–1945). The Allies promoted the alliance as a means to control German, Japanese and Italian aggression.
Allied war crimes include both alleged and legally proven violations of the laws of war by the Allies of World War II against either civilians or military personnel of the Axis powers.
After World War II there were from 560,000 to 760,000 Japanese personnel in the Soviet Union and Mongolia interned to work in labor camps as POWs. Of them, it is estimated that between 60,000-347,000 died in captivity.
This is a timeline of events that occurred during World War II in 1943.
This is a timeline of the events that stretched over the period of World War II from January 1945 to its conclusion and legal aftermath.
United States war crimes are the violations of the laws and customs of war of which the United States Armed Forces has committed after the signing of the Hague Conventions of 1899 and 1907. These have included the summary execution of captured enemy combatants, the mistreatment of prisoners during interrogation, the use of torture, and the use of violence against civilians and non-combatants.
Approximately three million German prisoners of war were captured by the Soviet Union during World War II, most of them during the great advances of the Red Army in the last year of the war. The POWs were employed as forced labor in the Soviet wartime economy and post-war reconstruction. By 1950 almost all surviving POWs had been released, with the last prisoner returning from the USSR in 1956. According to Soviet records 381,067 German Wehrmacht POWs died in NKVD camps.
Operation Agas was a series of reconnaissance operations carried out by Australia's Z Special Unit in 1945 during the final stages of World War II. This operation was part of the Borneo Campaign, supporting Allied operations to secure North Borneo. Another closely related operation codenamed Semut was carried out in Sarawak. Both operations combined and relayed their intelligence through the Stallion Project to Australian forces and carried out guerrilla warfare against the Japanese in the region with support of the local population. A total of five operations were undertaken, commencing in March 1945, continuing up to September and October 1945.
At the beginning of the Pacific War in 1941, the Imperial Japanese Army contained 51 divisions, most of which were stationed in China. A further 13 divisions defended the Manchurian-Soviet border, due to concerns about a possible attack by the Soviet Union. From 1942, troops were sent to Hong Kong, the Philippines, Thailand, Burma, Dutch East Indies, and Malaya. By 1945, there were 5.5 million men in the Imperial Japanese Army.
Before Pearl Harbor, the Japanese had already began imperial expansion in China (1937) and in other territories and islands. The Empire of Japan entered World War II in September 27, 1940, by signing the Tripartite Pact with Germany and Italy, though, it wasn't until the attack on Pearl Harbor on December 7, 1941, that the US entered the conflict. Over the course of seven hours there were coordinated Japanese attacks on the U.S.-held Philippines, Guam and Wake Island and on the British Empire in Borneo, Malaya, Singapore, and Hong Kong. The strategic goals of the offensive were to cripple the U.S. Pacific fleet, capture oil fields in the Dutch East Indies, and maintain their sphere of influence of China, East Asia, and also Korea. It was also to expand the outer reaches of the Japanese Empire to create a formidable defensive perimeter around newly acquired territory.
