You can visit the site on your own (highly recommended because you can go at your own pace, see what you want to see and have a much more meaningful experience) if you arrive before the guided tours start. Another option is to visit the Auschwitz II-Birkenau site first and then return after the guided tours finish to the first camp to avoid having to use the tour. The Auschwitz II-Birkenau site is open for visitors without the guide during the opening hours of the Memorial.
Following the camp's liberation, the Soviet government issued a statement, on 8 May 1945, that four million people had been killed on the site, a figure based on the capacity of the crematoria and later regarded as too high. Höss told prosecutors at Nuremberg that at least 2,500,000 people had been murdered in Auschwitz by gassing and burning, and that another 500,000 had died of starvation and disease. He testified that the figure of over two million had come from Eichmann.[d] In his memoirs, written in custody, he wrote that he regarded this figure as "far too high. Even Auschwitz had limits to its destructive possibilities." Raul Hilberg's 1961 work, The Destruction of the European Jews, estimated that up to 1,000,000 Jews had died in Auschwitz.
Further trials at Nuremberg took place between 1946 and 1949, which tried another 185 defendants. West Germany initially tried few ex-Nazis, but after the 1958 Ulm Einsatzkommando trial, the government set up a governmental agency to investigate crimes. Other trials of Nazis and collaborators took place in Western and Eastern Europe. In 1960, Mossad agents captured Adolf Eichmann in Argentina and brought him to Israel to stand trial on 15 indictments, including war crimes, crimes against humanity, and crimes against the Jewish people. He was convicted in December 1961 and executed in June 1962. Eichmann's trial and death revived interest in war criminals and the Holocaust in general.
Schindler grew up in Svitavy, Moravia, and worked in several trades until he joined the Abwehr, the military intelligence service of Nazi Germany, in 1936. He joined the Nazi Party in 1939. Prior to the German occupation of Czechoslovakia in 1938, he collected information on railways and troop movements for the German government. He was arrested for espionage by the Czechoslovak government but was released under the terms of the Munich Agreement in 1938. Schindler continued to collect information for the Nazis, working in Poland in 1939 before the invasion of Poland at the start of World War II. In 1939, Schindler acquired an enamelware factory in Kraków, Poland, which employed at the factory's peak in 1944 about 1,750 workers, of whom 1,000 were Jews. His Abwehr connections helped Schindler protect his Jewish workers from deportation and death in the Nazi concentration camps. As time went on, Schindler had to give Nazi officials ever larger bribes and gifts of luxury items obtainable only on the black market to keep his workers safe.
