Another important correction to the historical record: Itzhak Stern, played in the movie by Ben Kingsley, was actually a composite of a number of people, including Mietek Pemper, who played a crucial role in putting Oskar Schindler in the position to save many people. Pemper had the unfortunate task of being forced to work as the assistant to Amon Goth, the sadistic commandant of the Krakow-Płaszow concentration camp. In that position, Pemper passed along valuable information to Oskar. As the German war effort neared collapse, Pemper told Schindler he needed to expand into armaments because only factories deemed vital to the war effort would be viewed worth saving, along with, it was hoped, the workers in those factories.

The passengers had landing certificates and transit visas by the Cuban Director-General of Immigration, Manuel Benitez Gonzalez. But, a week before the ship left, Cuban President Federico Laredo Bru published a decree that overturned all recent landing certificates. For them to land in Cuba, they needed written authorization from the Cuban Secretaries of State and Labor and a $500 bond. Most of the passengers were not prepared for the bureaucratic mess they were about to face in Cuba.

Jews were forced to move, often to different cities or countries, and live in designated areas, referred to as ghettos. Most of the ghettos were “open” which meant Jews were free to come and go during the daytime. As time past, more and more ghettos became “closed” meaning that Jews were trapped and not allowed to leave. No ghettos were ever established within the borders of Germany and most were only meant as a temporary means of isolating Jews from the German population until they could be moved elsewhere.
These programmes are best seen as a series of linked genocides, each having its own history, background, purpose and significance in the Nazi scheme of things. The Holocaust was the biggest of the killing programmes and, in certain important ways, different from the others. The Jews figured in Nazi ideology as the arch-enemy of the 'Aryan race', and were targeted not merely for terror and repression but for complete extinction. The Nazis failed in this aim because they ran out of time, but they pursued it fanatically until their defeat in 1945. The Holocaust led to widespread public awareness of genocide and to modern efforts to prevent it, such as the 1948 UN Convention on Genocide.
Current estimates put the number of prisoners who passed through the concentration camp during its period of operation from 1943 to 1945 at around 120,000. Due to the destruction of the camp's files by the SS, not even half of them, around 55,000, are known by name.[10]:269 As mentioned above, treatment of prisoners by the SS varied between individual sections of the camp, with the inmates of the exchange camp generally being better treated than other prisoners, at least initially. However, in October 1943 the SS selected 1,800 men and women from the Sonderlager ("special camp"), Jews from Poland who held passports from Latin American countries. Since the governments of these nations mostly refused to honour the passports, these people had lost their value to the regime. Under the pretext of sending them to a fictitious "Lager Bergau", the SS had them transported to Auschwitz-Birkenau, where they were sent directly to the gas chambers and killed. In February and May 1944 another 350 prisoners from the "special camp" were sent to Auschwitz. Thus, out of the total of 14,600 prisoners in the exchange camp, at least 3,550 died, more than 1,400 of them at Belsen, and around 2,150 at Auschwitz.[10]:187
Conditions in the camp were good by concentration camp standards, and most prisoners were not subjected to forced labor. However, beginning in the spring of 1944 the situation deteriorated rapidly. In March, Belsen was redesignated an Ehrholungslager [Recovery Camp], where prisoners of other camps too sick to work were brought, though none received medical treatment. As the German Army retreated in the face of the advancing Allies, the concentration camps were evacuated and their prisoners sent to Belsen. The facilites in the camp were unable to accommodate the sudden influx of thousands of prisoners and all basic services - food, water and sanitation - collapsed, leading to the outbreak of disease. Anne Frank and her sister, Margot, died of typhus in March 1945, along with other prisoners in a typhus epidemic.
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]
Sometimes the mere presence of German troops in the vicinity was sufficient to spur a massacre. One example is what happened in the Polish village of Jedwabne, where neighbours murdered their Jewish neighbours. For years the massacre was blamed on the Germans, though many Poles likely knew that the local population had turned against its own Jews. In the Baltics, where the Germans were greeted as liberators by some segments of the population, the lure of political independence and the desire to erase any collaboration with the previous Soviet occupiers led nationalist bands to murder local Jews.
Immediately after the war, Erich Preuss, a former Dachau prisoner, set up an exhibit in the crematory building, located just outside the barbed wire enclosure of the concentration camp. American soldiers stationed in Germany were brought to Dachau to see the gas chamber, which they were told had been used to murder innocent inmates of the concentration camp. Mannequins were used in a display that was set up to illustrate how the Dachau prisoners were punished on the whipping block. During this time, the former concentration camp itself was off limits to visitors because it was filled with accused German war criminals awaiting the proceedings of the American Military Tribunals at Dachau, and later by homeless German refugees.
In early 1937, the SS, using prisoner labor, initiated construction of a large complex of buildings on the grounds of the original camp. The construction was officially completed in mid-August 1938 and the camp remained essentially unchanged and in operation until 1945. A crematorium that was next to, but not directly accessible from within the camp, was erected in 1942. KZ Dachau was therefore the longest running concentration camp of the Third Reich. The Dachau complex included other SS facilities beside the concentration camp—a leader school of the economic and civil service, the medical school of the SS, etc. The camp at that time was called a "protective custody camp," and occupied less than half of the area of the entire complex.[13]

My father supervised work parties in which Irma Grese was forced to carry corpses for burial and he described her as really beautiful but utterly evil. Most of the SS guards were evil and Dad had trouble stopping his men from shooting them out of hand, especially when the SS prisoners protested about having to work in burial details. He was tempted to do so himself. He told me that Bergen-Belsen brought home to him what they had been fighting, evil from the pit of hell itself.
In December 1944 SS-Hauptsturmführer Josef Kramer, previously at Auschwitz-Birkenau, became the new camp commandant, replacing SS-Hauptsturmführer Adolf Haas [de], who had been in post since the spring of 1943.[7] In January 1945, the SS took over the POW hospital and increased the size of Bergen-Belsen. As eastern concentration camps were evacuated before the advance of the Red Army, at least 85,000 people were transported in cattle cars or marched to Bergen-Belsen.[14] Before that the number of prisoners at Belsen had been much smaller. In July 1944 there were 7,300; by December 1944 the number had increased to 15,000; and by February 1945 it had risen to 22,000. Numbers then soared to around 60,000 by April 15, 1945.[7] This overcrowding led to a vast increase in deaths from disease: particularly typhus, as well as tuberculosis, typhoid fever, dysentery and malnutrition in a camp originally designed to hold about 10,000 inmates. At this point also, the special status of the exchange prisoners no longer applied. All inmates were subject to starvation and epidemics.[14]
