In Europe, these tribunals were set up under the authority of the London Charter, which only considered allegations of war crimes committed by people who acted in the interests of the Axis powers.According to an article in Der Spiegel by Klaus Wiegrefe, many personal memoirs of Allied soldiers have been willfully ignored by historians because they were at odds with the "greatest generation" mythology surrounding World War II.[4] Individual commentators such as the German historian and left-wing antiwar activist Jörg Friedrich have argued that Allied aerial bombardment of civilian areas and cultural targets in enemy territory, including the German cities of Cologne, Hamburg, and Dresden, the Abbey in Monte Cassino in Italy during the Battle of Monte Cassino,[5] the Japanese cities of Tokyo, Nagoya, Osaka, and especially the use of atomic bombs on Hiroshima and Nagasaki, which resulted in the total destruction of cities and the deaths of hundreds of thousands of civilians, should be considered war crimes;[6][7][8][9] however, other observers point out that no positive or specific international law with respect to aerial warfare existed prior to and during World War II[10] and that no Japanese and German officers were prosecuted at the post-World War II Allied war crime trials for the aerial raids on Shanghai, Chongqing, Warsaw, Rotterdam, and British cities during the Blitz.[11] According to Mitch-am and Avon Hohenstaufen, the Canadian army unit "The Loyal Edmonton Regiment" murdered German prisoners of war during the invasion of Sicily.[12] Charles P. Stacey, the Canadian official campaign historian, reports that on 14 April 1945 rumours spread that the popular commanding officer of the Argyll and Sutherland Highlanders of Canada, Lieutenant Colonel Frederick E. Wigle, had been killed by a civilian sniper.Anthony Clayton, in his book France, Soldiers, and Africa,[27] devotes several pages to the criminal activities of the Goumiers, which he partially ascribes to typical practices in their homeland.Various sources, including the Special Investigation Branch as well as evidences from Belgian reporters, said that rape and sexual harassment by British troops occurred frequently following the invasion of Sicily in 1943.[39] Though the Royal Military Police tended to turn a blind eye towards abuse of German prisoners and civilians who obstructed the army, rape was considered differently.[45] Arno was the third Italian hospital ship sunk by British aircraft after the loss of the Po in the Adriatic Sea to aerial torpedoes on 14 March 1941[46][47] and the bombing of the California off Syracuse on 11 August 1942.[50] During Operation Overlord, British line of communication troops conducted small-scale looting in Bayeux and Caen in France, following their liberation, in violation of the Hague Conventions.[52] According to an article in Der Spiegel by Klaus Wiegrefe, many personal memoirs of Allied soldiers have been wilfully ignored by historians until now because they were at odds with the "greatest generation" mythology surrounding World War II.In interviews with his biographer Charles Brandt, Sheeran recalled his war service with the Thunderbird Division as the time when he first developed a callousness to the taking of human life.[83] A study by Robert J. Lilly estimates that a total of 14,000 civilian women in England, France and Germany were raped by American GIs during World War II.The most infamous of these was the Katyn massacre, a series of mass executions of nearly 22,000 Polish military officers and intelligentsia carried out by the Soviet Union, specifically the NKVD in April and May 1940.[127] Dower suggests that most Japanese personnel were told that they would be "killed or tortured" if they fell into Allied hands and, as a consequence, most of those faced with defeat on the battlefield fought to the death or committed suicide.[128] In addition, it was held to be shamefully disgraceful for a Japanese soldier to surrender, leading many to commit suicide or to fight to the death regardless of any beliefs concerning their possible treatment as POWs.Vice Admiral Charles A. Lockwood asserted that the survivors were Japanese soldiers who had turned machine-gun and rifle fire on the Wahoo after she surfaced, and that such resistance was common in submarine warfare.[145] The survivors were later determined to have included Allied POWs of the Indian 2nd Battalion, 16th Punjab Regiment, who were guarded by Japanese Army Forces from the 26th Field Ordnance Depot.According to Richard J. Aldrich, a professor of history at the University of Warwick, who has published a study of the diaries kept by United States and Australian soldiers, they sometimes massacred prisoners of war.[153] This analysis is supported by British historian Niall Ferguson,[154] who also says that, in 1943, "a secret [U.S.] intelligence report noted that only the promise of ice cream and three days leave would ... induce American troops not to kill surrendering Japanese".That same year, efforts were taken by Allied high commanders to suppress "take no prisoners" attitudes,[154] among their own personnel (as these were affecting intelligence gathering) and to encourage Japanese soldiers to surrender.This, compounded by a previous Life magazine picture of a young woman with a skull trophy, was reprinted in the Japanese media and presented as a symbol of "American barbarism", causing national shock and outrage.[161] In a 13 June 1944 memorandum, the US Army Judge Advocate General, (JAG) Major General Myron C. Cramer, asserted that "such atrocious and brutal policies", were both "repugnant to the sensibilities of all civilized people"[159] and also violations of the Geneva Convention for the Amelioration of the Condition of the Wounded and Sick in Armies in the Field, which stated that: "After each engagement, the occupant of the field of battle shall take measures to search for the wounded and dead, and to protect them against pillage and maltreatment.[159] The US Navy JAG mirrored that opinion one week later, and also added that "the atrocious conduct of which some US personnel were guilty could lead to retaliation by the Japanese which would be justified under international law".[164] Okinawan historian Oshiro Masayasu (former director of the Okinawa Prefectural Historical Archives) writes based on several years of research: Soon after the U.S. Marines landed, all the women of a village on Motobu Peninsula fell into the hands of American soldiers.The article goes deeper into the matter and claims that the villagers' tale—true or not—is part of a "dark, long-kept secret" the unraveling of which "refocused attention on what historians say is one of the most widely ignored crimes of the war": 'the widespread rape of Okinawan women by American servicemen.[167] Professor of East Asian Studies and expert on Okinawa, Steve Rabson, said: "I have read many accounts of such rapes in Okinawan newspapers and books, but few people know about them or are willing to talk about them.Over five decades after the war had ended, in the late 1990s, the women who were believed to have been raped still overwhelmingly refused to give public statements, instead speaking through relatives and a number of historians and scholars.Samuel Saxton, a retired captain, explained that the American veterans and witnesses may have intentionally kept the rape a secret, largely out of shame: "It would be unfair for the public to get the impression that we were all a bunch of rapists after we worked so hard to serve our country.[173] After the surrender of Germany, the conditions of recently German personnel apprehended by the Allies significantly worsened; it is estimated that tens of thousands of prisoners died from hunger and disease at that stage.
