In the course of the war, the camp was staffed by 7,000 members of the German Schutzstaffel (SS), approximately 12 percent of whom were later convicted of war crimes. Several, including camp commandant Rudolf Höss, were executed. The Allies did not act on early reports of atrocities at the camp, and their failure to bomb the camp or its railways remains controversial. At least 802 prisoners tried to escape from Auschwitz, 144 successfully, and on 7 October 1944 two Sonderkommando units, consisting of prisoners assigned to staff the gas chambers, launched a brief, unsuccessful uprising.
The origins of blitzkrieg are in some doubt: if it existed, who contributed to it, whether it was part of German war strategy from 1933–1939. There has been a great deal of debate about whether it existed as a coherent military strategy. Many historians[who?] now think that blitzkrieg was not a military theory and the campaigns conducted by the Germans from 1939 to circa 1942 (with the exception of Operation Barbarossa) were improvised, rather than being based on a particular military strategy. Blitzkrieg had been called a Revolution in Military Affairs (RMA) but many writers and historians have concluded that the Germans did not invent a new form of warfare but applied new technologies to traditional ideas of Bewegungskrieg (manoeuvre warfare) to achieve decisive victory.
Jerzy Tabeau (prisoner no. 27273, registered as Jerzy Wesołowski) and Roman Cieliczko (no. 27089), both Polish prisoners, escaped on 19 November 1943; Tabeau made contact with the Polish underground and, between December 1943 and early 1944, wrote what became known as the Polish Major's report about the situation in the camp. On 27 April 1944, Rudolf Vrba (no. 44070) and Alfréd Wetzler (no. 29162) escaped to Slovakia, carrying detailed information to the Slovak Jewish Council about the gas chambers. The distribution of the Vrba-Wetzler report, and publication of parts of it in June 1944, helped to halt the deportation of Hungarian Jews to Auschwitz. On 27 May 1944, Arnost Rosin (no. 29858) and Czesław Mordowicz (no. 84216) also escaped to Slovakia; the Rosin-Mordowicz report was added to the Vrba-Wetzler and Tabeau reports to become what is known as the Auschwitz Protocols. The reports were first published in their entirety in November 1944 by the United States War Refugee Board, in a document entitled The Extermination Camps of Auschwitz (Oświęcim) and Birkenau in Upper Silesia.
After World War II, Schindler and his wife Emilie settled in Regensburg, Germany, until 1949, when they immigrated to Argentina. In 1957, permanently separated but not divorced from Emilie, Schindler returned alone to Germany. Schindler died in Germany, penniless and almost unknown, in October 1974. Many of those whose survival he facilitated—and their descendants—lobbied for and financed the transfer of his body for burial in Israel.
The direct reason for the establishment of the camp was the fact that mass arrests of Poles were increasing beyond the capacity of existing "local" prisons. The first transport of Poles reached KL Auschwitz from Tarnów prison on June 14, 1940. Initially, Auschwitz was to be one more concentration camp of the type that the Nazis had been setting up since the early 1930s. It functioned in this role throughout its existence, even when, beginning in 1942, it also became the largest of the death camps.
By July 1944, Germany was losing the war; the SS began closing down the easternmost concentration camps and deporting the remaining prisoners westward. Many were killed in Auschwitz and the Gross-Rosen concentration camp. Schindler convinced SS-Hauptsturmführer Amon Göth, commandant of the nearby Kraków-Płaszów concentration camp, to allow him to move his factory to Brněnec in the Protectorate of Bohemia and Moravia, thus sparing his workers from almost certain death in the gas chambers. Using names provided by Jewish Ghetto Police officer Marcel Goldberg, Göth's secretary Mietek Pemper compiled and typed the list of 1,200 Jews who travelled to Brünnlitz in October 1944. Schindler continued to bribe SS officials to prevent the execution of his workers until the end of World War II in Europe in May 1945, by which time he had spent his entire fortune on bribes and black market purchases of supplies for his workers.
