Browning concludes that Hitler ordered the genocide of the Jews in the Soviet Union during the period of what he terms “euphoria” just after the invasion of Russia, when victory appeared to be easily within Germany’s grasp. Browning dates this, as most recent historians do, to August-October 1941, in the context of a general “war of destruction” in the Soviet Union. Browning’s timetable thus reflects today’s consensus, although he does present a comprehensive array of evidence in support of this conclusion. With the failure of the German armies to gain a decisive victory in Russia, a failure that was becoming evident by October or November 1941, Nazi genocide began to turn toward the Jews under German control throughout Europe, beginning with the Jews of Poland, and employing the assembly-line techniques of the gas chambers in extermination camps like Treblinka and Auschwitz rather than the open-air shootings that the Einsatzgruppen invariably used during the first days of the invasion.
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.
