From the earliest years of the Nazi regime, German authorities persecuted homosexuals and others whose behavior did not match prescribed social norms. German police officials targeted thousands of political opponents (including Communists, Socialists, and trade unionists) and religious dissidents (such as Jehovah's Witnesses). Many of these individuals died as a result of incarceration and maltreatment.

He went on to say that the use of tanks "left much to be desired...Fear of enemy action against the flanks of the advance, fear which was to prove so disastrous to German prospects in the west in 1940 and in the Soviet Union in 1941, was present from the beginning of the war." John Ellis further asserted that "...there is considerable justice in Matthew Cooper's assertion that the panzer divisions were not given the kind of strategic mission that was to characterize authentic armored blitzkrieg, and were almost always closely subordinated to the various mass infantry armies."
At the three Reinhard camps the victims were killed by the exhaust fumes of stationary diesel engines.[279] Gold fillings were pulled from the corpses before burial, but the women's hair was cut before death. At Treblinka, to calm the victims, the arrival platform was made to look like a train station, complete with fake clock.[300] Majdanek used Zyklon-B gas in its gas chambers.[301] In contrast to Auschwitz, the three Reinhard camps were quite small.[302] Most of the victims at these camps were buried in pits at first. Sobibór and Bełżec began exhuming and burning bodies in late 1942, to hide the evidence, as did Treblinka in March 1943. The bodies were burned in open fireplaces and the remaining bones crushed into powder.[303]
Blitzkrieg means “lightning war”. It was an innovative military technique first used by the Germans in World War Two and was a tactic based on speed and surprise. Blitzkrieg relied on a military force be based around light tank units supported by planes and infantry (foot soldiers). The tactic was based on Alfred von Schlieffen’s ‘Schlieffen Plan’ – this was a doctrine formed during WWI that focused on quick miliatry victory. It was later developed in Germany by an army officer called Heinz Guderian who looked at new technologies, namely dive bombers and light tanks, to improve the German army’s manoeuvrability.
After the SS re-designated Plaszow as a concentration camp in August 1943, Schindler persuaded the SS to convert Emalia into a subcamp of Plaszow. In addition to the approximately 1,000 Jewish forced laborers registered as factory workers, Schindler permitted 450 Jews working in other nearby factories to live at Emalia as well. This saved them from the systematic brutality and arbitrary murder that was part of daily life in Plaszow.

The Germans did not achieve surprise and were not able to outflank or break through into enemy rear areas during the operation.[103] Several historians assert that Operation Citadel was planned and intended to be a blitzkrieg operation.[i] Many of the German participants who wrote about the operation after the war, including Manstein, make no mention of blitzkrieg in their accounts.[j] In 2000, Niklas Zetterling and Anders Frankson characterised only the southern pincer of the German offensive as a "classical blitzkrieg attack".[104] Pier Battistelli wrote that the operational planning marked a change in German offensive thinking away from blitzkrieg and that more priority was given to brute force and fire power than to speed and manoeuvre.[105]
Repeat selections took place several times during the day in roll calls. Inmates who had become weak or ill were separated from the ranks and sent to the gas chambers. A brutal regimen based on a set of punishments and torture was invoked in the camp. Few managed to survive. In Auschwitz-Birkenau, more than 1,100,000 Jews, 70,000 Poles, 25,000 Sinti and Roma (Gypsies) and some 15,000 prisoners of war from the USSR and other countries were murdered.
Schindler moved to West Germany after the war, where he was supported by assistance payments from Jewish relief organisations. After receiving a partial reimbursement for his wartime expenses, he moved with his wife, Emilie, to Argentina, where they took up farming. When he went bankrupt in 1958, Schindler left his wife and returned to Germany, where he failed at several business ventures and relied on financial support from Schindlerjuden ("Schindler Jews")—the people whose lives he had saved during the war. He and his wife, Emilie, were named Righteous Among the Nations by the Israeli government in 1993. He died on 9 October 1974 in Hildesheim, Germany, and was buried in Jerusalem on Mount Zion, the only member of the Nazi Party to be honoured in this way.
