The Wehrmacht War Crimes Bureau, 1939-1945 is a book by Alfred-Maurice de Zayas.
 It was published in November 1979 in Germany by Universitas/Langen Müller under the title "Die Wehrmacht-Untersuchungsstelle", and in America in 1989 under the title "The Wehrmacht War Crimes Bureau, 1939-1945" (University of Nebraska Press).
 Professor Howard S. Levie, an expert in international humanitarian law, provided the preface for the American version.
 The book describes some of the work of the Wehrmacht War Crimes Bureau, a special section of the legal department of the Wehrmacht High Command, which collected reports of alleged Allied and German war crimes for purposes of diplomatic protests, war crimes trials, and white books.
There are differences from one country to another regarding the definition of Japanese war crimes.
 War crimes have been broadly defined as violations of the laws or customs of war, which include crimes against either enemy combatants or enemy non-combatants.
 War crimes also included deliberate attacks on citizens and property of neutral states as they fall under the category of non-combatants, as at the attack on Pearl Harbor.
 Military personnel from the Empire of Japan have been accused and/or convicted of committing many such acts during the period of Japanese imperialism from the late 19th to mid-20th centuries.
 They have been accused of conducting a series of human rights abuses against civilians and prisoners of war (POWs) throughout east Asia and the western Pacific region.
 These events reached their height during the Second Sino-Japanese War of 1937–45 and the Asian and Pacific campaigns of World War II (1941–45).
Schindler's List is a 1993 American epic historical period drama film directed and co-produced by Steven Spielberg and scripted by Steven Zaillian.
 It is based on the novel "Schindler's Ark" by Australian novelist Thomas Keneally.
 The film relates a period in the life of Oskar Schindler, an ethnic German businessman, during which he saved the lives of more than a thousand mostly Polish-Jewish refugees from the Holocaust by employing them in his factories during World War II.
 It stars Liam Neeson as Schindler, Ralph Fiennes as SS officer Amon Göth, and Ben Kingsley as Schindler's Jewish accountant Itzhak Stern.
Amon Leopold Göth (] ; alternative spelling "Goeth"; 11 December 1908 – 13 September 1946;    ) was an Austrian SS-"Hauptsturmführer" (captain) and the commandant of the Kraków-Płaszów concentration camp in Płaszów in German-occupied Poland for most of the camp's existence during World War II.
Inheritance is a 2006 documentary film about Monika Hertwig a.k.a. Monika Christiane Knauss, the daughter of Ruth Irene Kalder and Amon Göth, Commandant of Kraków-Płaszów concentration camp.
 Monika Hertwig was 10 months old when her father was hanged in 1946 for war crimes, crimes against humanity and genocide.
 She discovered the truth about him only as a young adult, because her own mother told her in childhood that he was a good man and a war hero.
Arnold Büscher (16 December 1899, Bad Oeynhausen – 2 August 1949) was a German SS officer.
 At the rank of SS-"Obersturmführer", he was the second and last commandant of the Kraków-Płaszów concentration camp, succeeding Amon Göth, from September 1944 until about January 1945.
The article summarizes casualties in different theatres of World War II in Europe and North Africa.
 Only the military losses and civilian losses directly associated with hostilities are included into the article.
 The actions of the Axis' and Allied military or civilian authorities that fit the definition of genocide, or war crimes (including Nazi war crimes, Soviet war crimes, Allied war crimes, Holocaust, Nazi crimes against Soviet POWs "et caetera") are left beyond the scope of the present article.
James Gowing Godwin (12 March 1923–2 May 1995) was a Royal New Zealand Navy aviator, prisoner of war, war crimes investigator and colonial administrator.
 After the end of World War II, as a captain in the Australian Army he became an investigator with the Second Australian War Crimes Section in Tokyo in July 1947; he developed the case against Lieutenant General Takuma Nishimura for ordering the mass execution and cremation of 155 wounded Australian and Indian soldiers at war crimes at the Parit Sulong Massacre.
 He also worked for the First Australian War Crimes Section, based in Singapore, then worked for the British colonial service.
Helen Jonas-Rosenzweig (born Helena Sternlicht; 25 April 1925) is a Holocaust survivor interned during World War II at the Kraków-Płaszów concentration camp where she was forced to work as a maid for SS camp commandant Amon Göth.
Jennifer Teege (born 29 June 1970, Munich) is a German writer.
 Her maternal grandfather was Austrian Nazi concentration camp commander and war criminal Amon Göth.
 Her 2015 book "My Grandfather Would Have Shot Me" was a "New York Times" bestseller.
