^ Many of the German participants of Operation Citadel made no mention of blitzkrieg in their characterisation of the operation. Several German officers and commanders involved in the operation wrote their account of the battle after the war, and some of these postwar accounts were collected by the US Army. Some of these officers are: Theodor Busse (Newton 2002, pp. 3–27), Erhard Raus (Newton 2002, pp. 29–64), Friedrich Fangohr (Newton 2002, pp. 65–96), Peter von der Groeben (Newton 2002, pp. 97–144), Friedrich Wilhelm von Mellenthin (Mellenthin 1956, pp. 212–234), Erich von Manstein (Manstein 1983, pp. 443–449), and others.
Not long after acquiring his “Emalia” factory - which produced enamel goods and munitions to supply the German front - the removal of Jews to death camps began in earnest. Schindler's Jewish accountant put him in touch with the few Jews with any remaining wealth. They invested in his factory, and in return they would be able to work there and perhaps be spared. He was persuaded to hire more Jewish workers, designating their skills as “essential,” paying off the Nazis so they would allow them to stay in Kraków. Schindler was making money, but everyone in his factory was fed, no-one was beaten, no-one was killed. It became an oasis of humanity in a desert of moral torpor.
On January 20, 1942, several top officials of the German government met to officially coordinate the military and civilian administrative branches of the Nazi system to organize a system of mass murder of the Jews. This meeting, called the Wannsee Conference, "marked the beinning of the full-scale, comprehensive extermination operation [of the Jews] and laid the foundations for its organization, which started immediately after the conference ended" (Yahil, The Holocaust, p. 318).

What the arms, whose charges can be partly traced in tithing seals and boundary stones back to the 16th century, mean is unclear. The charge that the German blazon describes as a “wall anchor” (Maueranker) is not accepted as such by everyone, with some saying it could have been meant to be taken as a weaver’s reel. With a document from 22 July 1926, the interior minister of the People's State of Hesse granted the community the right to bear these arms.

The prisoners' days began at 4:30 am for the men (an hour later in winter), and earlier for the women, when the block supervisor sounded a gong and started beating inmates with sticks to encourage them to wash and use the latrines quickly.[106] Sanitary arrangements were atrocious, with few latrines and a lack of clean water. Each washhouse had to service thousands of prisoners. In sectors BIa and BIb in Auschwitz II-Birkenau, two buildings containing latrines and washrooms were installed in 1943. These contained troughs for washing and 90 faucets; the toilet facilities were "sewage channels" covered by concrete with 58 holes for seating. There were three barracks with washing facilities or toilets to serve 16 residential barracks in BIIa, and six washrooms/latrines for 32 barracks in BIIb, BIIc, BIId, and BIIe.[107] Primo Levi described a 1944 Auschwitz III washroom:
At Auschwitz, after the chambers were filled, the doors were shut and pellets of Zyklon-B were dropped into the chambers through vents,[293] releasing toxic prussic acid, or hydrogen cyanide.[294] Those inside died within 20 minutes; the speed of death depended on how close the inmate was standing to a gas vent, according to the commandant Rudolf Höss, who estimated that about one-third of the victims died immediately.[295] Johann Kremer, an SS doctor who oversaw the gassings, testified that: "Shouting and screaming of the victims could be heard through the opening and it was clear that they fought for their lives."[296] The gas was then pumped out, the bodies were removed, gold fillings in their teeth were extracted, and women's hair was cut.[297] The work was done by the Sonderkommando, work groups of mostly Jewish prisoners.[298] At Auschwitz, the bodies were at first buried in deep pits and covered with lime, but between September and November 1942, on the orders of Himmler, they were dug up and burned. In early 1943, new gas chambers and crematoria were built to accommodate the numbers.[299]
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.
