^ After the invasion of Poland, the Germans planned to set up a Jewish reservation in southeast Poland around the transit camp in Nisko, but the "Nisko Plan" failed, in part because it was opposed by Hans Frank, the new Governor-General of the General Government territory.[147][148][149] Adolf Eichmann was assigned to remove Jews from Germany, Austria, and the Protectorate of Bohemia and Moravia to the reservation.[150] Although the idea was to remove 80,000 Jews, Eichmann had managed to send only 4,700 by March 1940, and the plan was abandoned in April.[151] By mid-October the idea of a Jewish reservation had been revived by Heinrich Himmler, because of the influx of Germanic settlers into the Warthegau.[152] Resettlement continued until January 1941 under Odilo Globocnik,[153] and included both Jews and Poles.[154] By that time 95,000 Jews were already concentrated in the area,[155] but the plan to deport up to 600,000 additional Jews to the Lublin reservation failed for logistical and political reasons.[156]
Around Birkenau are several nature conservation areas and a considerable number of hiking paths. These are found on the one hand in the woods around Birkenau, but on the other hand, the Höhenweg (“Height Way”, European walking route E1, plateau path between Birkenau and Reisen), for example, is also worth visiting, as there is a striking view over Birkenau and Nieder-Liebersbach.
A memorandum dated July 31, 1941, from Hitler’s top commander Hermann Goering to Reinhard Heydrich, chief of the SD (the security service of the SS), referred to the need for an Endlösung (final solution) to “the Jewish question.” Beginning in September 1941, every person designated as a Jew in German-held territory was marked with a yellow star, making them open targets. Tens of thousands were soon being deported to the Polish ghettoes and German-occupied cities in the USSR.
The concept of blitzkrieg was formed by Prussian military tactics of the early 19th century, which recognized that victory could come only through forceful and swift action because of Prussia’s relatively limited economic resources. It had its origins with the Schwerpunktprinzip (“concentration principle”) proposed by Carl von Clausewitz in his seminal work On War (1832). Having studied generals who predated Napoleon, Clausewitz found that commanders of various armies had dispersed their forces without focused reasoning, which resulted in those forces’ being used inefficiently. So as to eliminate that wasteful use of manpower, he advocated for a concentration of force against an enemy. All employment of force should have an effective concentration in a single moment, with a single action, Clausewitz argued. Clausewitz called that concentration the Schwerpunkt (“centre of gravity”) where it was most dense, identifying it as the effective target for attack.
The death camp and slave-labour camp were interrelated. Newly arrived prisoners at the death camp were divided in a process known as Selektion. The young and the able-bodied were sent to work. Young children and their mothers and the old and infirm were sent directly to the gas chambers. Thousands of prisoners were also selected by the camp doctor, Josef Mengele, for medical experiments. Auschwitz doctors tested methods of sterilization on the prisoners, using massive doses of radiation, uterine injections, and other barbaric procedures. Experiments involving the killing of twins, upon whom autopsies were performed, were meant to provide information that would supposedly lead to the rapid expansion of the “Aryan race.”

Throughout the spring and summer of 1940, the German army expanded Hitler’s empire in Europe, conquering Denmark, Norway, the Netherlands, Belgium, Luxembourg and France. Beginning in 1941, Jews from all over the continent, as well as hundreds of thousands of European Gypsies, were transported to the Polish ghettoes. The German invasion of the Soviet Union in June 1941 marked a new level of brutality in warfare. Mobile killing units called Einsatzgruppenwould murder more than 500,000 Soviet Jews and others (usually by shooting) over the course of the German occupation.

In 1944, Josiah DuBois, Jr. wrote a memorandum to then-Secretary of the Treasury Henry Morgenthau, Jr. entitled “Report to the Secretary on the Acquiescence of This Government in the Murder of the Jews”, which condemned the bureaucratic interference of U.S. State Department policies in obstructing the evacuation of Holocaust Refugees from Romania and Occupied France. The Report would spur the Roosevelt administration to create the War Refugee Board later that year.

These concepts remained tactical and operational. Grand-strategic and economic planning in Adolf Hitler’s Reich were not shaped by a doctrine of lightning war. A familiar argument is that Nazi Germany deliberately rearmed in breadth rather than depth, proposing to tailor its force mix to specific situations in the context of a diplomatic strategy designed to keep Germany’s enemies isolated from one another. However, no significant data support such a grand design. Instead, the best evidence indicates that Hitler sought rearmament in both breadth and depth, with an economy oriented to military needs as completely as possible. Instead, far from coordinating their specific preparations, the army, navy, and air force competed so intensely for scarce raw materials that as early as 1938 their demands seriously overheated the ramshackle Nazi economy. Throughout the war the Wehrmacht’s inability to cooperate internally was one of Germany’s most significant military weaknesses–a far cry from the smoothly working machine that is the essence of blitzkrieg in popular myths.
Although effective in quick campaigns against Poland and France, blitzkrieg could not be sustained by Germany in later years. Blitzkrieg strategy has the inherent danger of the attacking force overextending its supply lines, and the strategy as a whole can be defeated by a determined foe who is willing to sacrifice territory for time in which to regroup and rearm, as the Soviets did on the Eastern Front. Tank and vehicle production was a constant problem for Germany; indeed, late in the war many panzer "divisions" had no more than a few dozen tanks. As the end of the war approached, Germany also experienced critical shortages in fuel and ammunition stocks as a result of Anglo-American strategic bombing. Although production of Luftwaffe fighter aircraft continued, they would be unable to fly for lack of fuel. What fuel there was went to panzer divisions, and even then they were not able to operate normally. Of those Tiger tanks lost against the United States Army, nearly half of them were abandoned for lack of fuel.
Another scene in the movie that Crowe believes never happened is the depiction of Oskar Schindler on horseback watching from a hill in 1943 as a young Jewish girl in a red coat seeks a hiding place during the ruthless closing of the Krakow ghetto. Crowe writes that Spielberg included the scene to show an epiphany, a moment that motivated Schindler into action. But it is unlikely during the middle of such a major action Oskar Schindler and his girlfriend would be taking a pleasure ride on horseback. “There is nothing to indicate that Oskar and his mistress were ever on Lasota Hill on March 13th and 14th. He was well aware of the coming Aktion and was more concerned about the fate of his Jewish workers,” notes Crowe.
^ Nothing appeared in Luftwaffe 'doctrine' stipulating "terror" as a major operational factor. The method of "terror", was denied to German aerial operations (and strategic bombing methods) by the Luftwaffe field manual The Conduct of Air Operations, Regulation 16, issued in 1935 (Corum 1992, pp. 167–169). Regulation 16 denied "terror" operations against civilians, and it was not until 1942 when indiscriminate "terror" operations, in which terror and civilian casualties become the primary target, took place (Corum 1997, pp. 7, 143).

The industrialization and scale of the murder was unprecedented. Killings were systematically conducted in virtually all areas of occupied Europe—more than 20 occupied countries.[40] Close to three million Jews in occupied Poland and between 700,000 and 2.5 million Jews in the Soviet Union were killed. Hundreds of thousands more died in the rest of Europe.[41] Victims were transported in sealed freight trains from all over Europe to extermination camps equipped with gas chambers.[42] The stationary facilities grew out of Nazi experiments with poison gas during the Aktion T4 mass murder ("euthanasia") programme against the disabled and mentally ill, which began in 1939.[43] The Germans set up six extermination camps in Poland: Auschwitz II-Birkenau (established October 1941); Majdanek (October 1941); Chełmno (December 1941); and the three Operation Reinhard camps, Belzec, Sobibor, and Treblinka, in 1942.[44] A seventh death camp, Maly Trostenets, was established near Minsk in Belarus, then part of the Reichskommissariat Ostland.[45] Discussions at the Wannsee Conference in January 1942 made it clear that the German "final solution of the Jewish question" was intended eventually to include Britain and all the neutral states in Europe, including Ireland, Switzerland, Turkey, Sweden, Portugal, and Spain.[46]
Buses leave Auschwitz I for Birkenau at a half past the hour, every hour. It costs two zloty and takes no more than five minutes. The experience of the camp is very different from Auschwitz I. For one thing it is much larger, covering over four hundred acres. It also retains the air of the place as it was when abandoned to a greater degree than the former camp. Some sixty seven buildings have survived virtually intact, and the interiors, with their stark wooden furnishings, take you right back to the war era. The other buildings remain as they were - some burnt to the ground and others massed up in heaps of rubble.
Almost all Jews within areas occupied by the Germans were killed. There were 3,020,000 Jews in the Soviet Union in 1939, and the losses were 1–1.1 million.[400] Around one million Jews were killed by the Einsatzgruppen in the occupied Soviet territories.[401][402] Of Poland's 3.3 million Jews, about 90 percent were killed.[369] Many more died in the ghettos of Poland before they could be deported.[403] The death camps accounted for half the number of Jews killed; 80–90 percent of death-camp victims are estimated to have been Jews.[394] At Auschwitz-Birkenau the Jewish death toll was 1.1 million;[286][404] Treblinka 870,000–925,000;[405] Bełżec 434,000–600,000;[406][287] Chełmno 152,000–320,000;[407][288] Sobibór 170,000–250,000;[408][291] and Majdanek 79,000.[289]

Meanwhile, beginning in the fall of 1939, Nazi officials selected around 70,000 Germans institutionalized for mental illness or disabilities to be gassed to death in the so-called Euthanasia Program. After prominent German religious leaders protested, Hitler put an end to the program in August 1941, though killings of the disabled continued in secrecy, and by 1945 some 275,000 people deemed handicapped from all over Europe had been killed. In hindsight, it seems clear that the Euthanasia Program functioned as a pilot for the Holocaust.
The Nuremberg trials were a series of military tribunals, held by the Allied forces after World War II in Nuremberg, Germany, to prosecute prominent members of the political, military, and economic leadership of Nazi Germany. The first of these trials was the 1945–1946 trial of the major war criminals before the International Military Tribunal (IMT).[456] This tribunal tried 22 political and military leaders of the Third Reich,[457] except for Adolf Hitler, Heinrich Himmler, and Joseph Goebbels, all of whom had committed suicide several months before.[456]
Estimates of Jewish participation in partisan units throughout Europe range from 20,000 to 100,000.[323] In the occupied Polish and Soviet territories, thousands of Jews fled into the swamps or forests and joined the partisans,[324] although the partisan movements did not always welcome them.[325] An estimated 20,000 to 30,000 joined the Soviet partisan movement.[326] One of the famous Jewish groups was the Bielski partisans in Belarus, led by the Bielski brothers.[324] Jews also joined Polish forces, including the Home Army. According to Timothy Snyder, "more Jews fought in the Warsaw Uprising of August 1944 than in the Warsaw Ghetto Uprising of April 1943".[327][r]
Between 1942 and 1944, the SS authorities at Auschwitz established 44 subcamps. Some of them were established within the officially designated “development” zone, including Budy, Rajsko, Tschechowitz, Harmense, and Babitz. Others, such as Blechhammer, Gleiwitz, Althammer, Fürstengrube, Laurahuette, and Eintrachthuette were located in Upper Silesia north and west of the Vistula River. Some subcamps, such as Freudenthal and Bruenn (Brno), were located in Moravia.
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]
The Germans invaded the Netherlands, Luxembourg, Belgium, and France in May 1940. In the Netherlands, the Germans installed Arthur Seyss-Inquart as Reichskommissar, who quickly began to persecute the approximately 140,000 Dutch Jews. Jews were forced out of their jobs and had to register with the government. Non-Jewish Dutch citizens protested these measures, and in February 1941 they staged a strike that was quickly crushed.[161] After Belgium's surrender at the end of May 1940, it was ruled by a German military governor, Alexander von Falkenhausen, who enacted anti-Jewish measures against the country's 90,000 Jews, many of whom were refugees from Germany or Eastern Europe.[162]

Schindler joined the separatist Sudeten German Party in 1935.[6] Although he was a citizen of Czechoslovakia, Schindler became a spy for the Abwehr, the military intelligence service of Nazi Germany, in 1936. He was assigned to Abwehrstelle II Commando VIII, based in Breslau.[7] He later told Czech police that he did it because he needed the money; by this time Schindler had a drinking problem and was chronically in debt.[8]
