The job was then offered to legendary filmmaker Martin Scorsese, who accepted. Scorsese was set to put the film into production when Spielberg had an epiphany on the set of the revisionist Peter Pan story Hook and realized that he was finally prepared to make Schindler’s List. To make up for the change of heart, Spielberg traded Scorsese the rights to a movie he’d been developing that Scorsese would make into his next film: the remake of Cape Fear.
Due to the number of sub-camps over a large area that comprised the Dachau concentration camp complex, many Allied units have been officially recognized by the United States Army Center of Military History and the United States Holocaust Memorial Museum as liberating units of Dachau, including: the 4th Infantry Division, 36th Infantry Division, 42nd Infantry Division, 45th Infantry Division, 63rd Infantry Division, 99th Infantry Division, 103rd Infantry Division, 10th Armored Division, 12th Armored Division, 14th Armored Division, 20th Armored Division, and the 101st Airborne Division.[92]
For a better sense of reality, Spielberg originally wanted to shoot the movie completely in Polish and German using subtitles, but he eventually decided against it because he felt that it would take away from the urgency and importance of the images onscreen. According to Spielberg, “I wanted people to watch the images, not read the subtitles. There’s too much safety in reading. It would have been an excuse to take their eyes off the screen and watch something else.”
Though the Nazis tried to keep operation of camps secret, the scale of the killing made this virtually impossible. Eyewitnesses brought reports of Nazi atrocities in Poland to the Allied governments, who were harshly criticized after the war for their failure to respond, or to publicize news of the mass slaughter. This lack of action was likely mostly due to the Allied focus on winning the war at hand, but was also a result of the general incomprehension with which news of the Holocaust was met and the denial and disbelief that such atrocities could be occurring on such a scale.
But if the 10,000 bodies found in the camp by the British liberators weren't victims of mass gassing, how did so many die in such a short time? It was easy for viewers of the British documentary film, made immediately after the liberation, to believe that the emaciated corpses were those of prisoners who had been deliberately starved to death by the evil Nazis, especially because the film made no mention of epidemics in the overcrowded camp, or that the camp was right in the middle of a war zone and had even been hit in an Allied bombing attack.
Marc Coyle (?) reached the camp two days before I did and was a guard so as soon as I got there I looked him up and he took me to the crematory. Dead SS troops were scattered around the grounds, but when we reached the furnace house we came upon a huge stack of corpses piled up like kindling, all nude so that their clothes wouldn't be wasted by the burning. There were furnaces for burning six bodies at once and on each side of them was a room twenty feet square crammed to the ceiling with more bodies - one big stinking rotten mess. Their faces purple, their eyes popping, and with a ludicrous (?) grin on each one. They were nothing but bones & skin. Coyle had assisted at ten autopsies the day before (wearing a gas mask) on ten bodies selected at random. Eight of them had advanced T.B., all had Typhus and extreme malnutrition symptoms. There were both women and children in the stack in addition to the men.

Over the years of its operation, from 1933 to 1945, thousands of Dachau prisoners died of disease, malnutrition and overwork. Thousands more were executed for infractions of camp rules. Starting in 1941, thousands of Soviet prisoners of war were sent to Dachau then shot to death at a nearby rifle range. In 1942, construction began at Dachau on Barrack X, a crematorium that eventually consisted of four sizeable ovens used to incinerate corpses. With the implementation in 1942 of Hitler’s “Final Solution” to systematically eradicate all European Jews, thousands of Dachau detainees were moved to Nazi extermination camps in Poland, where they died in gas chambers.
An Inspector General report resulting from a US Army investigation conducted between 3 and 8 May 1945 and titled, "American Army Investigation of Alleged Mistreatment of German Guards at Dachau," found that 21 plus "a number" of presumed SS men were killed with others being wounded after their surrender had been accepted.[94][95] In addition, 25 to 50 SS guards were estimated to have been killed by the liberated prisoners.[96] Lee Miller visited the camp just after liberation, and photographed several guards who were killed by soldiers or prisoners.[97]
In the postwar years, the camp continued in use. From 1945 through 1948, the camp was used by the Allies as a prison for SS officers awaiting trial. After 1948, when hundreds of thousands of ethnic Germans were expelled from eastern Europe, it held Germans from Czechoslovakia until they could be resettled. It also served as a military base for the United States, which maintained forces in the country. It was closed in 1960. At the insistence of survivors, various memorials have been constructed and installed here.[15]:138
By October of the same year the camp was being used by the U.S. Army as a place of confinement for war criminals, the SS and important witnesses.[101] It was also the site of the Dachau Trials for German war criminals, a site chosen for its symbolism. In 1948 the Bavarian government established housing for refugees on the site, and this remained for many years.[102] Among those held in the Dachau internment camp set up under the U.S. Army were Elsa Ehrich, Maria Mandl, and Elisabeth Ruppert.
Transportation between camps was often carried out in freight cars with prisoners packed tightly. Long delays would take place; prisoners might be confined in the cars on sidings for days.[190] In mid-1942 work camps began requiring newly arrived prisoners to be placed in quarantine for four weeks.[191] Prisoners wore colored triangles on their uniforms, the color of the triangle denoting the reason for their incarceration. Red signified a political prisoner, Jehovah's Witnesses had purple triangles, "asocials" and criminals wore black and green. Badges were pink for gay men and yellow for Jews.[192] Jews had a second yellow triangle worn with their original triangle, the two forming a six-pointed star.[193][194] In Auschwitz, prisoners were tattooed with an identification number on arrival.[195]
The most notorious physician was Josef Mengele, an SS officer who became the Auschwitz camp doctor on 30 May 1943.[54] Interested in genetics[54] and keen to experiment on twins, he would pick out subjects from the new arrivals during "selection" on the ramp, shouting "Zwillinge heraus!" (twins step forward!).[55] They would be measured, killed, and dissected. One of Mengele's assistants said in 1946 that he was told to send organs of interest to the directors of the "Anthropological Institute in Berlin-Dahlem". This is thought to refer to Mengele's academic supervisor, Otmar Freiherr von Verschuer , director from October 1942 of the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics in Berlin-Dahlem.[56][55][i] Mengele's experiments included placing subjects in pressure chambers, testing drugs on them, freezing them, attempting to change their eye color by injecting chemicals into children's eyes, and amputations and other surgeries.[59]
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]

In the summer of 1943, Stalag XI-C (311) was dissolved and Bergen-Belsen became a branch camp of Stalag XI-B. It served as the hospital for all Soviet POWs in the region until January 1945. Other inmates/patients were Italian military internees from August 1944 and, following the suppression of the Warsaw Uprising in October 1944, around 1,000 members of the Polish Home Army were imprisoned in a separate section of the POW camp.[6]
