At each of the death camps, special squads of Jewish slave laborers called Sonderkommandos were utilized to untangle the victims and remove them from the gas chamber. Next they extracted any gold fillings from teeth and searched body orifices for hidden valuables. The corpses were disposed of by various methods including mass burials, cremation in open fire pits or in specially designed crematory ovens such as those used at Auschwitz. All clothing, money, gold, jewelry, watches, eyeglasses and other valuables were sorted out then shipped back to Germany for re-use. Women's hair was sent to a firm in Bavaria for the manufacture of felt.
While the labour camps at Auschwitz and Majdanek used inmates for slave labour to support the German war effort, the extermination camps at Belzec, Treblinka, and Sobibor had one task alone: killing. At Treblinka a staff of 120, of whom only 30 were SS (the Nazi paramilitary corps), killed some 750,000 to 925,000 Jews during the camp’s 17 months of operation. At Belzec German records detail a staff of 104, including about 20 SS, who killed some 500,000 Jews in less than 10 months. At Sobibor they murdered between 200,000 and 250,000. These camps began operation during the spring and summer of 1942, when the ghettos of German-occupied Poland were filled with Jews. Once they had completed their missions—murder by gassing, or “resettlement in the east,” to use the language of the Wannsee protocols—the Nazis closed the camps. There were six extermination camps, all in German-occupied Poland, among the thousands of concentration and slave-labour camps throughout German-occupied Europe.
By the late 1930s there was a desperate search for countries of refuge. Those who could obtain visas and qualify under stringent quotas emigrated to the United States. Many went to Palestine, where the small Jewish community was willing to receive refugees. Still others sought refuge in neighbouring European countries. Most countries, however, were unwilling to receive large numbers of refugees.
Josef Mengele (/ˈmɛŋɡələ/; German: [ˈmɛŋələ]; 16 March 1911 – 7 February 1979) was a German Schutzstaffel (SS) officer and physician in Auschwitz concentration camp during World War II. He performed deadly human experiments on prisoners and was a member of the team of doctors who selected victims to be killed in the gas chambers. Arrivals that were judged able to work were admitted into the camp, while those deemed unsuitable for labor were sent to the gas chambers to be killed. With Red Army troops sweeping through Poland, Mengele was transferred 280 kilometers (170 mi) from Auschwitz to the Gross-Rosen concentration camp on 17 January 1945, just ten days before the arrival of the Soviet forces at Auschwitz. After the war, he fled to South America where he evaded capture for the rest of his life.
