Resistance also occurred inside the death camps. At Treblinka, Jewish inmates staged a revolt in August 1943, after which Himmler ordered the camp dismantled. At Sobibor, a big escape occurred in October 1943, as Jews and Soviet POWs killed 11 SS men and broke out, with 300 making it safely into nearby woods. Of those 300, most were hunted down and only fifty survived. Himmler then closed Sobibor. At Auschwitz-Birkenau, Jewish Sonderkommandos managed to destroy crematory number four in October 1944.
Mengele sailed to Argentina in July 1949, assisted by a network of former SS members. He initially lived in and around Buenos Aires, then fled to Paraguay in 1959 and Brazil in 1960, while being sought by West Germany, Israel, and Nazi hunters such as Simon Wiesenthal who wanted to bring him to trial. He eluded capture in spite of extradition requests by the West German government and clandestine operations by the Israeli intelligence agency Mossad. He drowned in 1979 after suffering a stroke while swimming off the Brazilian coast, and was buried under a false name. His remains were disinterred and positively identified by forensic examination in 1985.
