Auschwitz-Birkenau

Auschwitz starts as a concentration camp. During the summer of 1941, Heinrich Himmler, the head of the SS, decided to transform Auschwitz into a killing centre. Auschwitz-Birkenau became the largest camp operated by the Nazis. Over one million Jews were killed in the camp, along with approximately 74,000 Poles, 21,000 Roma and 15,000 Soviet prisoners of war. More people were deported and killed in Auschwitz-Birkenau than in any other Nazi camp during the war and it has thus become a key symbol of the Holocaust.

Treblinka

Treblinka is the main killing centre for the Jews of the Warsaw ghetto. The purpose of the camp is to kill every deportee within a few hours of arrival. The camp is far from perfectly organized and the disposal of corpses is a major issue. An unbearable smell surrounds the place and people in the area cannot be unaware of the massive killing operations. An estimated 870,000 to 925,000 people were killed in Treblinka, either shot or gassed in chambers.

Majdanek

Majdanek is built to provide forced labourers for the future permanent German settlements in occupied Poland and Soviet Union. Between October 1942 and September 1943, two, possibly three, gas chambers are built at Majdanek to eliminate prisoners no longer capable of work, using Zyklon B and carbon monoxide gas. Majdanek is known for the terrible abuse inflicted on forced labourers; thousands of them die of torture and starvation. Gassing, for the most part, is reserved for Jews. Between 95,000 and 130,000 people are estimated to have been killed in Majdanek. Among them, were between 80,000 and 92,000 Jews, as well as Poles and Soviet prisoners of war.

Chelmno

Chelmno is the first killing centre created by the SS, near the city of Lodz. The “killing centre” consists of a manor in the town of Chelmno and a large forest clearing. The SS use vans to kill Jews and Roma with the carbon monoxide gas from the vans’ exhaust. The same technique had been used to kill institutionalized handicapped children and adults in the so-called Euthanasia or T4 program in Germany. Between December 1941 and the end of 1942, the Nazis and their henchmen kill about 152,000 Jews, and about 5 000 Roma in the Chelmno gas vans.

Shoes should be tied together in pairs and placed in the area marked for shoes. Afterward, one must go completely naked to the showers." Belzec, circa 1942-1943.

Belzec

Belzec has fixed facilities for gassing that use carbon monoxide gas from the exhaust fumes of a motor vehicle engine. After expansion in June 1942, the camp has six gas chambers capable of killing 1,500 people at one time. Belzec, like Treblinka and Sobibor, was created solely to efficiently kill thousands of people as part of Operation Reinhard. In only 9 months of killing operations, an estimated 434,000 to 600,000 Jews are killed in Belzec along with an undetermined number of Roma. Only one inmate from Belzec survived the war.

Sobibor

Part of Operation Reinhard, Sobibor operates for a year and a half, during which approximately 170,000 to 250,000 Jews are killed by carbon monoxide gassing. The guards select some Jews as workers in the killing process, and the rest of the deportees are gassed immediately. Sobibor camp officers are German and Austrian SS members. Camp guards under their command are ethnic Germans as well as Soviet prisoners of war, primarily from Ukraine. Some administrators of the killing centre had previously worked at one of the so-called euthanasia program killing centres in Germany.

Prisoners' Revolt in Treblinka

On August 2, 1943, prisoners assigned to forced labour stage a revolt in Treblinka. The prisoners seize weapons from the camp armoury, but SS guards in the camp discover the plot before it could be completed. Hundreds of prisoners storm the main gate in an attempt to escape. More than 300 prisoners escape, but the SS and police personnel eventually recapture and kill about 200 of them. Deportations to Treblinka stop a few weeks after the uprising and the camp is dismantled.

Revolt in Sobibor

In the summer of 1943, Polish Jewish forced labourers form an underground group, led by Leon Feldhendler, in the Sobibor killing centre. On September 23, 1943, 2,000 Soviet Jewish prisoners of war from Minsk are deported to the camp. One of them, Alexander Petsjerski, who had been a lieutenant in the Red Army, join the Felhendler group and prepare an uprising. At 4:00 p.m. on October 14, 1943, the first SS soldier is killed with an axe. Ten more SS men are killed, as are several Ukrainian guards. About 300 prisoners escape. Most are killed by their Nazi pursuers or die crossing the minefields surrounding the camp. Only 50 of the escapees survived the war. After the revolt, the Germans started dismantling the camp and planted the site with crops to hide the evidence of the mass graves.

Sonderkommados revolt in Birkenau

Members of the Jewish prisoner Sonderkommando, the prisoners who were forced to remove bodies from the gas chambers and operate the crematoria, stage an uprising. On October 7, 1944 they blow up the roof of Birkenau's Crematorium IV and kill three guards. The gun powder had been smuggled by four female prisoners working in one of the camp's ammunition factories. However, the SS guards were quick to suppress the revolt and all the prisoners involved in the uprising were killed.
