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]

More than 40 sub-camps, exploiting the prisoners as slave laborers, were also founded, mainly as various sorts of German industrial plants and farms, between 1942 and 1944. The largest of them was called Buna (Monowitz, with ten thousand prisoners) and was opened by the camp administration in 1942 on the grounds of the Buna-Werke synthetic rubber and fuel plant, six kilometers from the Auschwitz camp. The factory was built during the war by the German IG Farbenindustrie cartel, and the SS supplied prisoner labor. On November 1943, the Buna sub-camp became the seat of the commandant of the third part of the camp, Auschwitz III, to which some other Auschwitz sub-camps were subordinated.
Birkenau had its first documentary mention in 795 in the Lorsch Codex as a cell of the Lorsch Abbey. As one of the Abbey’s holdings, it passed into the ownership of the Archbishopric of Mainz in 1232. The centres of Hornbach and Balzenbach, on the other hand, belonged to the Electorate of the Palatinate, meaning that after the Reformation, they belonged to different denominations. In 1532 the town hall was built, and in 1771 the palace, Schloss Birkenau, of the Lords of Wambolt von Umstadt. By 1964, the population had grown to more than 5,000. In 1967 the community was recognized as a recreational resort (Erholungsort) and in 1979 as an open-air resort (Luftkurort). Owing to the only slight tourism, however, it has not reapplied for this designation. In 1995, Birkenau celebrated its 1,200-year jubilee.
The Blitzkrieg was fundamentally about moving away from the tried and tested methods of modern warfare and creating a new, more effective doctrine. To that end, Hitler had given his full backing to Guderian. Ironically, he had got his idea for Blitzkrieg from two officers – one from France and one from Britain and he had copied and broadened what they had put on paper. In Britain and France, however, the cavalry regiments ruled supreme and they were adamant that the tanks would not get any influence in their armies. The High Commands of both countries were dominated by the old traditional cavalry regiments and their political pull was great. These were the type of officers despised by Hitler and he took to his Panzer officer, Guderian, over the old officers that were in the German Army (the Wehrmacht). 
At this time only the main camp, later known as Auschwitz I, had been established. Himmler ordered the construction of a second camp for 100,000 inmates on the site of the village of Brzezinka, roughly two miles from the main camp. This second camp, now known as Birkenau or Auschwitz II, was initially intended to be filled with captured Russian POWs who would provide the slave labor to build the SS “utopia” in Upper Silesia. Chemical giant I G Farben expressed an interest in utilizing this labor force, and extensive construction work began in October 1941 under terrible conditions and with massive loss of life. About 10,000 Russian POWs died in this process. The greater part of the apparatus of mass extermination was eventually built in the Birkenau camp and the majority of the victims were murdered here.

Keneally’s novel is not the same as most novels. First it is a novel that deals with historical events. This is not too uncommon, though it is less common than non-historical fiction. What makes Schindler’s List special is its absolute accuracy. Keneally studiously sifted through all of the documents regarding Oskar Schindler and those he rescued, as well as interviewed many of those he rescued. The result is a nuanced portrait of Schindler that is imminently readable for any audience. His skill as a novelist allows Keneally to portray the horror of Goeth’s road paved with Jewish gravestones in a way that a strict historian could not. Where Keneally
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.
