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.

Birkenau (Auschwitz II) was established in October 1941, three kilometers from Auschwitz. Exterminations in Birkenau began in March 1942. There were four gas chambers in the camp that used Zyklon B gas. Until November 1944 the camp functioned as a factory for mass murder, receiving transports from all over Europe. Most of those brought to the camp were Jews and nearly all were immediately sent to the gas chambers. Only a small percentage was selected for labor in the camp itself, labor in munitions plants at satellite camps, or the “medical” experiments of Dr. Josef Mengele and his staff. In the spring and summer of 1944, the rate of extermination was increased as the Jews of Hungary and the Lodz ghetto were brought to the camp.

Our perception of land operations in the Second World War has...been distorted by an excessive emphasis upon the hardware employed. The main focus of attention has been the tank and the formations that employed it, most notably the (German) panzer divisions. Despite the fact that only 40 of the 520 German divisions that saw combat were panzer divisions (there were also an extra 24 motorised/panzergrenadier divisions), the history of German operations has consistently almost exclusively been written largely in terms of blitzkrieg and has concentrated almost exclusively upon the exploits of the mechanized formations. Even more misleadingly, this presentation of ground combat as a largely armored confrontation has been extended to cover Allied operations, so that in the popular imagination the exploits of the British and Commonwealth Armies, with only 11 armored divisions out of 73 (that saw combat), and of the Americans in Europe, with only 16 out of 59, are typified by tanks sweeping around the Western Desert or trying to keep up with Patton in the race through Sicily and across northern France. Of course, these armored forces did play a somewhat more important role in operations than the simple proportions might indicate, but it still has to be stressed that they in no way dominated the battlefield or precipitated the evolution of completely new modes of warfare.
Thus although the Nazi 'Final Solution' was one genocide among many, it had features that made it stand out from all the rest as well. Unlike all the others it was bounded neither by space nor by time. It was launched not against a local or regional obstacle, but at a world-enemy seen as operating on a global scale. It was bound to an even larger plan of racial reordering and reconstruction involving further genocidal killing on an almost unimaginable scale, aimed, however, at clearing the way in a particular region – Eastern Europe – for a further struggle against the Jews and those the Nazis regarded as their puppets. It was set in motion by ideologues who saw world history in racial terms. It was, in part, carried out by industrial methods. These things all make it unique.

SS-Obergruppenführer Reinhard Heydrich, head of the Reich Main Security Office (Reichssicherheitshauptamt or RSHA), convened what became known as the Wannsee Conference on 20 January 1942 at Am Großen Wannsee 56–58, a villa in Berlin's Wannsee suburb.[256][257] The meeting had been scheduled for 9 December 1941, and invitations had been sent on 29 November, but it had been postponed.[258]

Use of armoured forces was crucial for both sides on the Eastern Front. Operation Barbarossa, the German invasion of the Soviet Union in 1941, involved a number of breakthroughs and encirclements by motorised forces. Its goal according to Führer Directive 21 (18 December 1940) was "to destroy the Russian forces deployed in the West and to prevent their escape into the wide-open spaces of Russia."[90] The Red Army was to be destroyed west of the Dvina and Dnieper rivers, which were about 500 kilometres (310 mi) east of the Soviet border, to be followed by a mopping-up operation. The surprise attack resulted in the near annihilation of the Voyenno-Vozdushnye Sily (VVS, Soviet Air Force) by simultaneous attacks on airfields,[91] allowing the Luftwaffe to achieve total air supremacy over all the battlefields within the first week.[92][93] On the ground, four German panzer groups outflanked and encircled disorganised Red Army units, while the marching infantry completed the encirclements and defeated the trapped forces.[94] In late July, after 2nd Panzer Group (commanded by Guderian) captured the watersheds of the Dvina and Dnieper rivers near Smolensk, the panzers had to defend the encirclement, because the marching infantry divisions were still hundreds of kilometres to the west.[91]
Entrance is free, without a ticket, though donations are encouraged. Because of the large numbers of visitors entry to the Auschwitz-I site is exclusively on a guided group basis during the middle part of the day - as of 2019, between 10am and 12pm during December, between 10am and 1pm in November, January, February and March, between 10am and 4pm in April, May, September and October, and between 9am and 5pm in June, July and August.

When Germany invaded Poland in September 1939, triggering World War II, Adolf Hitler ordered that the Polish leadership and intelligentsia be destroyed.[16] Approximately 65,000 civilians, viewed as inferior to the Aryan master race, had been killed by the end of 1939. In addition to leaders of Polish society, the Nazis killed Jews, prostitutes, the Roma, and the mentally ill.[17][18] SS-Obergruppenführer Reinhard Heydrich, then head of the Gestapo, ordered on 21 September 1939 that Polish Jews be rounded up and concentrated into cities with good rail links. Initially the intention was to deport them to points further east, or possibly to Madagascar.[19] Two years later, in June 1941, in an attempt to obtain new territory, Hitler invaded the Soviet Union.[8]
An inmate's first encounter with the camp, if they were being registered and not sent straight to the gas chamber, would be at the prisoner reception centre, where they were tattooed, shaved, disinfected, and given their striped prison uniform. Built between 1942 and 1944, the center contained a bathhouse, laundry, and 19 gas chambers for delousing clothes. Debórah Dwork and Robert Jan van Pelt write that inmates would then leave this area via a porch that faced the gate with the Arbeit macht frei sign. The prisoner reception center of Auschwitz I became the visitor reception center of the Auschwitz-Birkenau Memorial and Museum.[20]
In order to gain a more personal perspective on the film, Spielberg traveled to Poland before principal photography began to interview Holocaust survivors and visit the real-life locations that he planned to portray in the movie. While there, he visited the former Gestapo headquarters on Pomorska Street, Schindler’s actual apartment, and Amon Goeth’s villa.
Near the end of the movie Schindler’s List, a famous scene depicts Oskar Schindler departing his factory at the end of the war and crying without consolation over his inability to save even more lives. (The scene was even parodied in an episode of Seinfeld.) “The idea that Oskar collapsed sobbing into Itzhak Stern’s arms and bemoaned his failure to save more Jews is preposterous,” writes Crowe. “Oskar was proud of all he had done to save Brunnlitz’s Jews and said so in his speech earlier that evening.”
In the summer of 1942, when Germany launched another offensive in the southern USSR against Stalingrad and the Caucasus, the Soviets again lost tremendous amounts of territory, only to counter-attack once more during winter. German gains were ultimately limited by Hitler diverting forces from the attack on Stalingrad itself and seeking to pursue a drive to the Caucasus oilfields simultaneously as opposed to subsequently as the original plan had envisaged.
In 1939, shortly after the war began, the Germans initiated the T4 Program—framed euphemistically as a “euthanasia” program—for the murder of intellectually or physically disabled and emotionally disturbed Germans who by their very existence violated the Nazi ideal of Aryan supremacy. They were termed “life unworthy of life.” An economic justification was also employed as these Germans were considered “useless eaters.” The Nazis pioneered the use of gas chambers and mass crematoria under this program. The murder of the disabled was the training ground for key personnel who were to later staff the death camps of Aktion Reinhard. The German public protested these murders. The Roman Catholic bishop of Münster, Clemens August, Graf von Galen, preached against them, and the T4 program was formally halted. Nonetheless, the murder and sterilization of these German “Aryans” continued secretly throughout the war.
Once a strategic target had been selected, Stuka dive bombers were sent in to ‘soften’ up the enemy, destroy all rail lines, communication centres and major rail links. This was done as the German tanks were approaching and the planes withdrew only at the last minute so that the enemy did not have time to recover their senses when the tanks attacked supported by infantry. 
Adam Tooze wrote that the German economy was being prepared for a long war. The expenditure for this war was extensive and put the economy under severe strain. The German leadership were concerned less with how to balance the civilian economy and the needs of civilian consumption but to figure out how to best prepare the economy for total war. Once war had begun, Hitler urged his economic experts to abandon caution and expend all available resources on the war effort but the expansion plans only gradually gained momentum in 1941. Tooze wrote that the huge armament plans in the pre-war period did not indicate any clear-sighted blitzkrieg economy or strategy.[134]

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.
