War crimes in World War II

World War II saw the largest scale of war crimes and crimes against humanity ever committed in an armed conflict, mostly against civilians and specific groups (e.g. Jews, Homosexuals, mentally ill and disabled people) and POWs. Most of these crimes were carried out by the Axis powers who constantly violated the rules of war and the Geneva Convention on Prisoners of War, mostly by Nazi Germany and Imperial Japan.

This is a list of war crimes committed during World War II.

Concurrent with World War II
Incident	type of crime	Persons responsible	Notes
Katyń massacre	War crimes (murder of Polish intelligentsia)	Lavrenty Beria, Joseph Stalin	An NKVD-committed massacre of tens of thousands of Polish officers and intelligentsia throughout the spring of 1940. Originally believed to have been committed by the Nazis in 1941 (after the invasion of eastern Poland and the USSR), it was finally admitted by Mikhail Gorbachev in 1990 that it had been a Soviet operation.
Invasion of Estonia, Latvia and Lithuania	War crimes	Vladimir Dekanozov, Andrey Vyshinsky, Andrei Zhdanov, Ivan Serov, Joseph Stalin	An NKVD-committed deportation of hundreds of thousands of Estonian, Latvian, and Lithuanian intelligentsia, land owners and their families in June 1941 and again in March 1949.
NKVD prisoner massacres	War crimes; torture; mass murder	Ivan Serov, Joseph Stalin	An NKVD-committed mass murder.
Anglo-Soviet invasion of Iran	Crimes against peace (waging aggressive war with Iran)	No prosecutions	In contravention of the 1928 Kellogg-Briand Pact and the 1907 Hague Convention (III), the Soviet Union and Britain jointly invaded neutral Iran without a declaration of war on 25 August 1941 for reasons such as securing the Allied supply lines to the USSR (see the Persian Corridor) and limiting German influence there (the Shah of Iran, Reza Shah, was considered friendly to Nazi Germany).
Deportation of the Chechens and Ingush	Crimes against humanity, ethnic cleansing, genocide	No prosecutions	Deportation of the entire Chechen and Ingush population to Siberia or Centra Asia in 1944. It was acknowledged by the European Parliament as an act of genocide.
Deportation of the Crimean Tatars	Crimes against humanity, ethnic cleansing	No prosecutions	Forced transfer of the entire Crimean Tatar population to Central Asia or Siberia in 1944.
Nemmersdorf massacre, East Prussia	War crimes	No prosecutions	Nemmersdorf (today Mayakovskoye in Kaliningrad Oblast) was one of the first German settlements to fall to the advancing Red Army on 22 October 1944. It was recaptured by the Germans soon afterwards and the German authorities reported that the Red Army killed civilians there. Nazi propaganda widely disseminated the description of the event with horrible details, supposedly to boost the determination of German soldiers to resist the general Soviet advance. Because the incident was investigated by the Nazis and reports were disseminated as Nazi propaganda, discerning the facts from the fiction of the incident is difficult.
Invasion of East Prussia Flight and expulsion of Germans from Poland during and after World War II Expulsion of Germans after World War II	Crimes against humanity (mass expulsion)	?	War crimes committed against German civilian population by the Red Army in occupied Eastern and Central Germany, and against ethnic-German populations of Poland, Czechoslovakia, Hungary and Jugoslavia. The number of civilian victims in the years 1944–46 is estimated in at least 300,000, not all victims of war crimes; many died from starvation, cold weather and diseases.
Treuenbrietzen	Crimes against humanity (Mass murder of civilians)	?	Following the capture of the German city of Treuenbrietzen after fierce fighting. Over a period of several days at the end of April and beginning of May roughly 1000 inhabitants of the city, most of them men, were executed by Soviet troops.
Rape during the Soviet occupation of Poland (1944–1947)	War crimes (mass rape)	?	Joanna Ostrowska and Marcin Zaremba of the Polish Academy of Sciences wrote that rapes of the Polish women reached a mass scale during the Red Army's Winter Offensive of 1945.
Battle of Berlin	War crimes (Mass rape)	?	(description/notes missing)
Przyszowice massacre	War crimes; crimes against humanity	No prosecution	A massacre perpetrated by the Red Army against civilian inhabitants of the Polish village of Przyszowice in Upper Silesia during the period 26 to 28 January 1945. Sources vary on the number of victims, which range from 54 to over 60 – and possibly as many as 69.
Gegenmiao massacre	War crimes; crimes against humanity	No prosecution	A massacre perpetrated by the Red Army against Japanese refugees in Inner Mongolia during the Soviet invasion of Manchuria. The Red Army murdered over 1,000 Japanese refugees by the end of the massacre.

Crimes perpetrated by the United Kingdom

See also: British war crimes

Incident	Type of crime	Persons responsible	Notes
Unrestricted submarine warfare against merchant shipping	Breach of London Naval Treaty (1930)	No prosecutions; Allied representatives admitted responsibility at Nuremberg Trials; questionable whether war crime or a breach of a treaty.	It was the conclusion of the Nuremberg Trials of Karl Dönitz that Britain had been in breach of the Treaty "in particular of an order of the British Admiralty announced on 8 May 1940, according to which all vessels should be sunk at sight in the Skagerrak."
Anglo-Soviet invasion of Iran	Crimes against peace (waging aggressive war against Iran)	No prosecutions	In contravention of the 1928 Kellogg-Briand Pact and the 1907 Hague Convention (III), Britain and the Soviet Union jointly invaded neutral Iran without a declaration of war on 25 August 1941 for reasons such as securing the Allied supply lines to the USSR (see the Persian Corridor) and limiting German influence there (the Shah of Iran, Reza Shah, was considered friendly to Nazi Germany).
HMS Torbay incident	War crimes (murder of shipwreck survivors)	No prosecutions	In July 1941, the submarine HMS Torbay (under the command of Anthony Miers) was based in the Mediterranean where it sank several German ships. On two occasions, once off the coast of Alexandria, Egypt, and the other off the coast of Crete, the crew attacked and killed dozens of shipwrecked German sailors and troops. None of the shipwrecked survivors posed a major threat to Torbay's crew. Miers made no attempt to hide his actions, and reported them in his official logs. He received a strongly worded reprimand from his superiors following the first incident. Miers' actions violated the Hague Convention of 1907, which banned the killing of shipwreck survivors under any circumstances.
Sinking of German hospital ship Tubingen	War crimes (attacking hospital ships)	No prosecutions	On 18 November 1944, the German hospital ship Tubingen was sunk by two British Beaufighter bombers off Pola, in the Adriatic Sea. The vessel, which had paid a brief visit to the Allied-controlled port of Bari to pick up German wounded under the auspices of the Red Cross, was attacked with rockets nine times, despite the calm sea and good weather allowed a clear identification of the ship's Red Cross markings. Six crewmembers were killed. American author Alfred M. de Zayas, who evaluated the 266 extant volumes of the Wehrmacht War Crimes Bureau, identifies the sinking of Tübingen and other German hospital ships as war crimes according to the Hague Convention (X) of 1907.

Crimes perpetrated by the United States

See also: United States war crimes

Incident	Type of crime	Persons responsible	Notes
Unrestricted submarine warfare against merchant shipping	Breach of London Naval Treaty (1930)	No prosecutions; Chester Nimitz admitted responsibility at Nuremberg Trials; questionable whether war crime or a breach of a treaty.	During the post war Nuremberg Trials, in evidence presented at the trial of Karl Dönitz on his orders to the U-boat fleet to breach the London Rules, Admiral Chester Nimitz stated that unrestricted submarine warfare was carried on in the Pacific Ocean by the United States from the first day that nation entered the war.
Canicattì massacre	War crimes (murder of civilians)	Lieutenant Colonel George H. McCaffrey was never prosecuted and died in 1954	During the Allied invasion of Sicily, eight civilians were killed by Lieutenant Colonel George H. McCaffrey, though the exact number of casualties is uncertain.
Biscari Massacre	War crimes (murder of POWs)	Sergeant Horace T. West: court-martialed for murder, found guilty, stripped of rank and sentenced to life in prison, albeit he was released as a private one year later. Captain John T. Compton was court-martialed for killing 40 POWs in his charge. He claimed to be following orders. The investigating officer and the Judge Advocate declared that Compton's actions were unlawful, but he was acquitted. Compton was killed in action in November 1943.	Following the capture of Biscari Airfield in Sicily on 14 July 1943, seventy-six German and Italian POWs were shot by American troops of the 180th Regimental Combat Team, 45th Division during the Allied invasion of Sicily. These killings occurred in two separate incidents between July and August 1943.
Dachau liberation reprisals	War crimes (murder of POWs)	Investigated by U.S. forces, found lack of evidence to charge any individual, and a lack of evidence of any practice or policy; however, did find that SS guards were separated from Wehrmacht (regular German Army) prisoners before their deaths.	Some Death's Head SS guards of the Dachau concentration camp allegedly attempted to escape, and were shot.
Salina, Utah POW massacre	War crimes (murder of POWs)	Private Clarence V. Bertucci determined to be insane and confined to a mental institution	Private Clarence V. Bertucci fired a machine gun from one of the guard towers into the tents that were being used to accommodate the German prisoners of war. Nine were killed and 20 were wounded.
American mutilation of Japanese war dead	War crimes (abuse of remains)	Though there are no known prosecutions, the occasional mutilation of Japanese remains were recognised to have been conducted by U.S. forces, declared to be atrocities, and explicitly forbidden by order of the U.S. Judge Advocate General in 1943–1944.	Many dead Japanese were desecrated and/or mutilated, for example by taking body parts (such as skulls) as souvenirs or trophies. This is in violation of the law and custom of war, as well as the 1929 Geneva Convention on the Sick and Wounded which was paraphrased as saying "After every engagement, the belligerent who remains in possession of the field shall take measures to search for wounded and the dead and to protect them from robbery and ill-treatment." in a 1944 memorandum for the U.S. Assistant Chief of the Staff.

Crimes perpetrated by Canada

See also: Razing of Friesoythe

Incident	Type of crime	Persons responsible	Notes
Razing of Friesoythe	Breach of The 1907 Convention Respecting the Laws and Customs of War on Land (Hague IV), Article 23, which prohibits acts that "destroy or seize the enemy's property, unless such destruction or seizure be imperatively demanded by the necessities of war."	No investigation; No prosecutions. Major-general Christopher Vokes commander of the Canadian 4th Armoured Division freely admitted ordering the action, commenting in his autobiography that he had "No feeling of remorse over the elimination of Friesoythe."	In April 1945 the town of Friesoythe in north-west Germany was deliberately destroyed by the Canadian 4th Armoured Division acting on the orders of its commander, Major-general Christopher Vokes. The destruction was ordered in retaliation for the killing of a Canadian battalion commander. Vokes may have believed at the time that this killing had been carried out by German civilians. The rubble of the town was used to fill craters in the local roads.

Crimes perpetrated by the Yugoslav Partisans

Armed conflict		Perpetrator
World War II in Yugoslavia		Yugoslav Partisans
Incident	Type of crime	Persons responsible	Notes
Bleiburg repatriations	War crimes, crimes against humanity, death marches	No prosecutions.	The victims were Yugoslav collaborationist troops (ethnic Croats, Serbs, and Slovenes), executed without trial as an act of vengeance for the genocide committed by the pro-Axis collaborationist regimes (in particular the Ustaše) installed by the Nazis during the World War II occupation of Yugoslavia. Civilians were also killed. Estimates vary significantly, questioned by a number of historians.
Foibe massacres	War crimes, crimes against humanity, murder of prisoners of war and civilians, ethnic cleansing	No prosecutions.	Following Italy's 1943 armistice with the Allied powers up to 1947, OZNA and Yugoslav Partisans executed in Julian March (Karst Region and Istria), Kvarner and Dalmatia a number between 11,000 and 20,000 of the local ethnic Italian population (Istrian Italians and Dalmatian Italians), as well against anti-communists in general (even Croats and Slovenes), usually associated with Fascism, Nazism and collaboration with Axis, as well as against real, potential or presumed opponents of Tito communism. The type of attack was state terrorism, reprisal killings, and ethnic cleansing against Italians. The foibe massacres were followed by the Istrian–Dalmatian exodus.
Communist purges in Serbia in 1944–1945	War crimes, crimes against humanity, ethnic cleansing	No prosecutions.	1944–1945 killings of ethnic Hungarians in Bačka.
Persecution of Danube Swabians	War crimes, crimes against humanity, ethnic cleansing	In a unanimously approved motion in 1950, the Federal Council called on the Federal Government to commit itself, based on the prisoner of war agreement, to the return of German prisoners of war condemned in the Soviet Union and in Yugoslavia. Federal Chancellor Konrad Adenauer described in January 1950 the convictions of German prisoners of war in Yugoslavia as "crimes and crimes against humanity".	In Yugoslavia in particular, with many exceptions, the Danube Swabian minority "collaborated . . . with the occupation". Consequently, on 21 November 1944 the Presidium of the AVNOJ (the Yugoslav parliament) declared the ethnic German minority in Yugoslavia collectively hostile to the Yugoslav state. The AVNOJ Presidium issued a decree that ordered the government confiscation of all property of Nazi Germany and its citizens in Yugoslavia, persons of ethnic German nationality (regardless of citizenship), and collaborators. The decision acquired the force of law on 6 February 1945. Of a pre-war population of about 350,000 ethnic Germans in the Vojvodina, the 1958 census revealed 32,000 left. Officially, Yugoslavia denied the forcible starvation and killing of their Schwowisch populations, but reconstruction of the labor camps reveals that of the 170,000 Danube Swabians interned from 1944 to 1948, over 50,000 died of mistreatment. About 55,000 people died in the concentration camps, another 31,000 died serving in the German armed forces, and about 31,000 disappeared, mostly likely dead, with another 37,000 still unaccounted for. Thus the total victims of the war and subsequent ethnic cleansing and killings comprised about 30% of the pre-war German population. In addition, 35,000–40,000 Swabian children under age sixteen were separated from their parents and force into prison camps and re-education orphanages. Many were adopted by Serbian Partisan families.

Axis powers

The Axis powers (Nazi Germany, Fascist Italy, and Imperial Japan) were some of the most systematic perpetrators of war crimes in modern history. The factors which contributed to Axis war crimes included Nazi racial theories, the desire for "living space" which was used as a justification for the eradication of native populations, and militaristic indoctrination that encouraged the terrorization of conquered peoples and prisoners of war. The Holocaust, the German attack on the Soviet Union and the German occupation of much of Europe, the Japanese invasion and occupation of Manchuria, the Japanese invasion of China and the Japanese occupation of the Philippines all contributed to well over half of all of the civilian deaths in World War II as well as the conflicts that led up to the war. Even before post-war revelations of atrocities, Axis military forces were notorious for their brutal treatment of captured combatants.

Crimes perpetrated by Germany

Further information: Nazi Germany, German war crimes § World War II, War crimes in occupied Poland during World War II § Nazi German crimes against the Polish nation, Nazi crimes against the Polish nation, and Consequences of Nazism

According to the Nuremberg Trials, there were four major categories of crimes alleged against the German political leadership, the ruling party NSDAP, the military high command, the paramilitary SS, the security services, the civil occupation authorities, as well as individual government officials (including members of the civil service or the diplomatic corps), soldiers or members of paramilitary formations, industrialists, bankers and media proprietors, each with individual events that made up the major charges. The crime of genocide was later raised to a separate, fifth category.

   • The genocidal kidnapping of children by Nazi Germany for programmes such as Lebensborn

     

     Kidnapping of Polish children during the "resettlement" operation in Zamość county

At least 10 million, and perhaps over 20 million perished directly and indirectly due to the commission of crimes against humanity and war crimes by Hitler's regime, of which the Holocaust lives on in particular infamy, for its particularly cruel nature and scope, and the industrialised nature of the genocide of Jewish citizens of states invaded or controlled by the Nazi regime. At least 5.9 million Jews were murdered by the Nazis, or 66 to 78% of Europe's Jewish population, although a complete count may never be known. Though much of Continental Europe suffered under the Nazi occupation, Poland, in particular, was the state most devastated by these crimes, with 90% of its Jews as well as many ethnic Poles slaughtered by the Nazis and their affiliates. After the war, from 1945 to 1949, the Nazi regime was put on trial in two tribunals in Nuremberg, Germany by the victorious Allied powers.

The first tribunal indicted 24 major Nazi war criminals, and resulted in 19 convictions (of which 12 led to death sentences) and 3 acquittals, 2 of the accused died before a verdict was rendered, at least one of which by killing himself with cyanide. The second tribunal indicted 185 members of the military, economic, and political leadership of Nazi Germany, of which 142 were convicted and 35 were acquitted. In subsequent decades, approximately 20 additional war criminals who escaped capture in the immediate aftermath of World War II were tried in West Germany and Israel. In Germany and many other European nations, the Nazi Party and denial of the Holocaust is outlawed.

In 1958, all charges were dropped and sentences were reduced.	Following the US invasion of Luzon in 1944, the Japanese high command ordered that all POWs remaining in the island are to be exterminated at all cost. As a result, on 14 December 1944, units from the Japanese Fourteenth Area Army stationed in the Puerto Princesa POW camp in Palawan rounded up 150 remaining POWs still garrisoned in the camp, herded them into air raid shelters, before dousing the shelters with gasoline and setting it on fire.

Yamashita pleaded inability to act and lack of knowledge of the massacre, due to his commanding other operations in the area. The defense failed, establishing the Yamashita Standard, which holds that a commander who makes no meaningful effort to uncover and stop atrocities is as culpable as if he had ordered them.

Crimes perpetrated by the Chetniks

See also: Chetnik war crimes in World War II

Chetnik ideology revolved around the notion of a Greater Serbia within the borders of Yugoslavia, to be created out of all territories in which Serbs were found, even if the numbers were small. A directive dated 20 December 1941, addressed to newly appointed commanders in Montenegro, Major Đorđije Lašić and Captain Pavle Đurišić, outlined, among other things, the cleansing of all non-Serb elements in order to create a Greater Serbia:

1. The struggle for the liberty of our whole nation under the scepter of His Majesty King Peter II;
2. the creation of a Great Yugoslavia and within it of a Great Serbia which is to be ethnically pure and is to include Serbia, Montenegro, Bosnia and Herzegovina, Srijem, the Banat, and Bačka;
3. the struggle for the inclusion into Yugoslavia of all still unliberated Slovene territories under the Italians and Germans (Trieste, Gorizia, Istria, and Carinthia) as well as Bulgaria, and northern Albania with Skadar;
4. the cleansing of the state territory of all national minorities and a-national elements;
5. the creation of contiguous frontiers between Serbia and Montenegro, as well as between Serbia and Slovenia by cleansing the Muslim population from Sandžak and the Muslim and Croat populations from Bosnia and Herzegovina.
   — Directive of 20 December 1941

Chetniks in Šumadija kill a Partisan through heart extraction

The Chetniks systemically massacred Muslims in villages that they captured. In late autumn of 1941 the Italians handed over the towns of Višegrad, Goražde, Foča and the surrounding areas, in south-east Bosnia to the Chetniks to run as a puppet administration and NDH forces were compelled by the Italians to withdraw from there. After the Chetniks gained control of Goražde on 29 November 1941, they began a massacre of Home Guard prisoners and NDH officials that became a systematic massacre of the local Muslim civilian population.

Several hundred Muslims were murdered and their bodies were left hanging in the town or thrown into the Drina river. On 5 December 1941, the Chetniks received the town of Foča from the Italians and proceeded to massacre around 500 Muslims. Additional massacres against the Muslims in the area of Foča took place in August 1942. In total, more than 2000 people were killed in Foča.

In early January, Chetniks entered Srebrenica and killed around 1000 Muslim civilians there and in nearby villages. Around the same time the Chetniks made their way to Višegrad where deaths were reportedly in the thousands. Massacres continued in the following months in the region. In the village of Žepa alone about three hundred were killed in late 1941. In early January, Chetniks massacred fifty-four Muslims in Čelebić and burned down the village. On 3 March, Chetniks burned forty-two Muslim villagers to death in Drakan.

In early January 1943, and again in early February, Montenegrin Chetnik units were ordered to carry out "cleansing actions" against Muslims, first in the Bijelo Polje county in Sandžak and then in February in the Čajniče county and part of Foča county in southeastern Bosnia, and in part of the Pljevlja county in Sandžak.

Pavle Đurišić, the officer in charge of these operations, reported to Mihailović, Chief of Staff of the Supreme Command, that on 10 January 1943: "thirty-three Muslim villages had been burned down, and 400 Muslim fighters (members of the Muslim self-protection militia supported by the Italians) and about 1,000 women and children had been killed, as against 14 Chetnik dead and 26 wounded".

In another report sent by Đurišić dated 13 February 1943, he reported that: "Chetniks killed about 1,200 Muslim fighters and about 8,000 old people, women, and children; Chetnik losses in the action were 22 killed and 32 wounded". He added that "during the operation the total destruction of the Muslim inhabitants was carried out regardless of sex and age". The total number of deaths caused by the anti-Muslim operations between January and February 1943 is estimated at 10,000. The casualty rate would have been higher had a great number of Muslims not already fled the area, most to Sarajevo, when the February action began. According to a statement from the Chetnik Supreme Command from 24 February 1943, these were countermeasures taken against Muslim aggressive activities; however, all circumstances show that these massacres were committed in accordance with implementing the directive of 20 December 1941.

Actions against the Croats were of a smaller scale but comparable in action. In early October 1942 in the village of Gata, where an estimated 100 people were killed and many homes burnt in reprisal taken for the destruction of roads in the area carried out on the Italians' account. That same month, formations under the command of Petar Baćović and Dobroslav Jevđević, who were participating in the Italian Operation Alfa in the area of Prozor, massacred over 500 Croats and Muslims and burnt numerous villages. Baćović noted that "Our Chetniks killed all men 15 years of age or older. ... Seventeen villages were burned to the ground." Mario Roatta, commander of the Italian Second Army, objected to these "massive slaughters" of noncombatant civilians and threatened to halt Italian aid to the Chetniks if they did not end.

Crimes perpetrated by the Ustashas

The Ustaša intended to create an ethnically "pure" Greater Croatia, and they viewed those Serbs then living in Croatia, Bosnia and Herzegovina as the biggest obstacle to this goal. Ustasha ministers Mile Budak, Mirko Puk and Milovan Žanić declared in May 1941 that the goal of the new Ustasha policy was an ethnically pure Croatia. The strategy to achieve their goal was:

1. One-third of the Serbs were to be killed
2. One-third of the Serbs were to be expelled
3. One-third of the Serbs were to be forcibly converted to Catholicism

The Independent State of Croatia government cooperated with Nazi Germany in the Holocaust and exercised their own version of the genocide against Serbs, as well as Jews and Gypsies (Roma) inside its borders. State policy towards Serbs had first been declared in the words of Milovan Žanić, a minister of the NDH Legislative council, on 2 May 1941:

This country can only be a Croatian country, and there is no method we would hesitate to use in order to make it truly Croatian and cleanse it of Serbs, who have for centuries endangered us and who will endanger us again if they are given the opportunity.

According to the Simon Wiesenthal Center (citing the Encyclopedia of the Holocaust), "Ustasa terrorists killed 500,000 Serbs, expelled 250,000 and forced 250,000 to convert to Roman Catholicism. They murdered thousands of Jews and Gypsies." The execution methods used by the Ustasha were particularly brutal and sadistic and often included torture, dismemberment or decapitation. A Gestapo report to Heinrich Himmler from 1942 stated, "The Ustaše committed their deeds in a bestial manner not only against males of conscript age but especially against helpless old people, women and children."

Numerous concentration camps were built in the NDH, most notably Jasenovac, the largest, where around 100,000 Serbs, Jews, Roma, as well as a number of Croatian and Muslim political dissidents, died, mostly from torture and starvation. It was established in August 1941 and not dismantled until April 1945, shortly before the end of the war. Jasenovac was a complex of five subcamps and three smaller camps spread out over 240 square kilometres (93 sq mi), in relatively close proximity to each other, on the bank of the Sava river. Most of the camp was at Jasenovac, about 100 km (62 mi) southeast of Zagreb. The complex also included large grounds at Donja Gradina directly across the Sava River, the Jastrebarsko children's camp to the northwest, and the Stara Gradiška camp (Jasenovac V) for women and children to the southeast.

Unlike Nazi camps, most murders at Jasenovac were done manually using hammers, axes, knives and other implements. According to testimony, on the night of 29 August 1942, guards at the camp organised a competition to see who could slaughter the most inmates, with guard and former Franciscan priest Petar Brzica winning by cutting the throats of 1,360 inmates. A special knife called a "Srbosjek" (Serb-cutter) was designed for the slaughtering of prisoners. Prisoners were sometimes tied with barbed wire, then taken to a ramp near to the Sava River where weights were placed on the wires, their throats and stomachs slashed before their bodies were dumped into the river. After unsuccessful experiments with gas vans, camp commander Vjekoslav Luburić had a gas chamber built at Jasenovac V, where a considerable number of inmates were killed during a three-month experiment with sulfur dioxide and Zyklon B, but this method was abandoned due to poor construction. The Ustashe cremated living inmates as well as corpses. Other methods of torture and killing done included: inserting hot nails under finger nails, mutilating parts of the body including plucking out eyeballs, tightening chains around ones head until the skull fractured and the eyes popped and also, placing salt in open wounds. Women were subjected to rape and torture, including breast mutilation. Pregnant women had their wombs cut out.

An escape attempt on 22 April 1945 by 600 male inmates failed and only 84 male prisoners escaped successfully. The remainder and about 400 other prisoners were then murdered by Ustasha guards, despite the fact that they knew the war was ending with Germany's capitulation. All the female inmates from the women's camp (more than 700) had been massacred by the guards the previous day. The guards then destroyed the camp and everything associated with it was burned to the ground. Other concentration camps were the Đakovo camp, Gospić camp, Jadovno camp, Kruščica camp and the Lepoglava camp.

Ustasha militias and death squads also burnt villages and killed thousands of civilian Serbs in the country-side in sadistic ways with various weapons and tools. Men, women, children were hacked to death, thrown alive into pits and down ravines, or set on fire in churches. Some Serb villages near Srebrenica and Ozren were wholly massacred, while children were found impaled by stakes in villages between Vlasenica and Kladanj. The Glina massacres, where thousands of Serbs were killed, are among the more notable instances of Ustasha cruelty.

Ante Pavelić, leader of the Ustasha, fled to Argentina and Spain which gave him protection, and was never extradited to stand trial for his war crimes. Pavelić died on 28 December 1959 at the Hospital Alemán in Madrid, where the Roman Catholic church had helped him to gain asylum, at the age of 70 from gunshot wounds sustained in an earlier assassination attempt by Montenegrin Blagoje Jovović. Some other prominent Ustashe figures and their respective fates:

• Andrija Artuković, Croatian Minister of Interior. Died in Croatian custody.

Crimes perpetrated by Ukrainian nationalists

The Ukrainian OUN-B group, along with their military force—Ukrainian Insurgent Army (UPA)—are responsible for a genocide on the Polish population in Volhynia and Eastern Galicia. Starting in March 1943, with its peak in the summer 1943, as many as 80,000–100,000 were killed. Although the main target were Poles, many Jews, Czechs and those Ukrainians unwilling to participate in the crimes, were massacred as well. Lacking good armament and ammunition, UPA members commonly used tools such as axes and pitchforks for the slaughter. As a result of these massacres, almost the entire non-Ukrainian population of Volhynia was either killed or forced to flee.

UPA commanders responsible for the genocide:

• Roman Shukhevych – general of the Ukrainian Insurgent Army. As a leader of the UPA he was to be aware and to approve the project of ethnic cleansing in Volhynia and Eastern Galicia.
• Dmytro Klyachkivsky – colonel of the UPA. He gave the order "to wipe out an entire Polish male population between 16 and 60 years old" (according to the research of the Ukrainian historians, this citation may be falsified by the Soviet intelligence). Klyachkivsky is regarded as the main initiator of the massacres.
• Mykola Lebed – one of the OUN leaders, and UPA fighter. By the National Archives, he is described as "Ukrainian fascist leader and suspected Nazi collaborator"
• Stepan Bandera – leader of the OUN-B. His view was to remove all Poles, who were hostile towards the OUN, and assimilate the rest of them. The role of the main architect of the massacres is often assigned to him. However, he was imprisoned in German concentration camp since 1941, so there is a strong suspicion that he wasn't fully aware of events in Volhynia.
