Though classified as an armaments factory, the Brünnlitz plant produced just one wagonload of live ammunition in just under eight months of operation. By presenting bogus production figures, Schindler justified the existence of the subcamp as an armaments factory. This facilitated the survival of over 1,000 Jews, sparing them the horrors and brutality of conventional camp life. Schindler left Brünnlitz only on May 9, 1945, the day that Soviet troops liberated the camp.
Aware that as witnesses to the killings they would eventually be killed themselves, the Sonderkommandos of Birkenau Kommando III staged an uprising on 7 October 1944, following an announcement that some of them would be selected to be "transferred to another camp"—a common Nazi ruse for the murder of prisoners. They attacked the SS guards with stones, axes, and makeshift hand grenades, which they also used to damage Crematorium IV and set it on fire. As the SS set up machine guns to attack the prisoners in Crematorium IV, the Sonderkommandos in Crematorium II also revolted, some of them managing to escape the compound. The rebellion was suppressed by nightfall.
Almost all Jews within areas occupied by the Germans were killed. There were 3,020,000 Jews in the Soviet Union in 1939, and the losses were 1–1.1 million. Around one million Jews were killed by the Einsatzgruppen in the occupied Soviet territories. Of Poland's 3.3 million Jews, about 90 percent were killed. Many more died in the ghettos of Poland before they could be deported. The death camps accounted for half the number of Jews killed; 80–90 percent of death-camp victims are estimated to have been Jews. At Auschwitz-Birkenau the Jewish death toll was 1.1 million; Treblinka 870,000–925,000; Bełżec 434,000–600,000; Chełmno 152,000–320,000; Sobibór 170,000–250,000; and Majdanek 79,000.
