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.
Many of the naked corpses found in the camp were left out until May 13, two weeks after the liberation, so that American Congressmen, newspaper reporters and as many American soldiers as possible could view the horror. Thirty male citizens from the town of Dachau were brought to the camp and forced to view the rotting corpses, even though the typhus epidemic was still raging in the camp, and the Germans had not been vaccinated.
Around 50,000 German gay men were jailed between 1933 and 1945, and 5,000–15,000 are estimated to have been sent to concentration camps. It is not known how many died during the Holocaust.[413][449] James Steakley writes that what mattered in Germany was criminal intent or character, rather than acts, and the "gesundes Volksempfinden" ("healthy sensibility of the people") became the guiding legal principle.[450] In 1936, Himmler created the Reich Central Office for the Combating of Homosexuality and Abortion.[451] The Gestapo raided gay bars, tracked individuals using the address books of those they arrested, used the subscription lists of gay magazines to find others, and encouraged people to report suspected homosexual behavior and to scrutinize the behavior of their neighbors.[450] Lesbians were left relatively unaffected;[413] the Nazis saw them as "asocials", rather than sexual deviants.[452] Gay men convicted between 1933 and 1944 were sent to camps for "rehabilitation", where they were identified by pink triangles.[450] Hundreds were castrated, sometimes "voluntarily" to avoid criminal sentences.[453] Steakley writes that the full extent of gay suffering was slow to emerge after the war. Many victims kept their stories to themselves because homosexuality remained criminalized in postwar Germany.[450]

While there were only 23 main camps between 1933 to 1945, the Nazi regime established some 20,000 other camps used for forced labor, transit or temporary internment. During the Holocaust it is estimated that 6 million Jews were slaughtered along with, 3 million Soviet prisoners of war, 3 million Polish Catholics, 700,000 Serbians, 250,000 Gypsies, Sinti, and Lalleri, 80,000 Germans (for political reasons), 70,000 German handicapped, 12,000 homosexuals, and 2,500 Jehovah’s Witnesses.

Here over an acre of ground lay dead and dying people. You could not see which was which. ... The living lay with their heads against the corpses and around them moved the awful, ghostly procession of emaciated, aimless people, with nothing to do and with no hope of life, unable to move out of your way, unable to look at the terrible sights around them ... Babies had been born here, tiny wizened things that could not live. ... A mother, driven mad, screamed at a British sentry to give her milk for her child, and thrust the tiny mite into his arms. ... He opened the bundle and found the baby had been dead for days. This day at Belsen was the most horrible of my life.
Paradoxically, at the same time that Germany tried to rid itself of its Jews via forced emigration, its territorial expansions kept bringing more Jews under its control. Germany annexed Austria in March 1938 and the Sudetenland (now in the Czech Republic) in September 1938. It established control over the Protectorate of Bohemia and Moravia (now in the Czech Republic) in March 1939. When Germany invaded Poland on September 1, 1939, the “Jewish question” became urgent. When the division of Poland between Germany and the Soviet Union was complete, more than two million more Jews had come under German control. For a time, the Nazis considered shipping the Jews to the island of Madagascar, off the southeast coast of Africa, but discarded the plan as impractical; the Nazis had not prevailed in the Battle of Britain, the seas had become a war zone, and the resources required for such a massive deportation were scarce.

More camps opened in the spring and summer of 1942, when the Nazis began systematically clearing the ghettos in Poland and rounding up Jews in western Europe for 'deportation to the East'. The killing of the Polish Jews, code-named 'Project Reinhardt', was carried out in three camps: Treblinka, near Warsaw (850,000 victims); Belzec, in south-eastern Poland (650,000 victims); and Sobibor, in east-central Poland (250,000 victims). Some Jews from western Europe were sometimes taken to these camps as well, but most were killed at the biggest and most advanced of the death camps, Auschwitz.

As Allied forces advanced toward Germany, the Germans began to more prisoners from concentration camps near the front to prevent the liberation of large numbers of prisoners. Transports from the evacuated camps arrived continuously at Dachau, resulting in a dramatic deterioration of conditions. After days of travel, with little or no food or water, the prisoners arrived weak and exhausted, near death. Typhus epidemics became a serious problem due to overcrowding, poor sanitary conditions, and the weakened state of the prisoners.

Some of the inmates were exempt from work because they were too old or too young, but a few of the older prisoners worked on the herb farm. According to Paul Berben, "Statistics made by the camp administration on 16th February 1945 list 2,309 men and 44 women aged between 50 and 60 and 5,465 men and 12 women over 60." These figures are for the main camp at Dachau and all the subcamps.
September 26, 1942 - SS begins cashing in possessions and valuables of Jews from Auschwitz and Majdanek. German banknotes are sent to the Reichs Bank. Foreign currency, gold, jewels and other valuables are sent to SS Headquarters of the Economic Administration. Watches, clocks and pens are distributed to troops at the front. Clothing is distributed to German families. By February 1943, over 800 boxcars of confiscated goods will have left Auschwitz.

Britain's attitude to Jewish refugees from Nazi-controlled areas was strongly influenced by its role as the mandatory power in Palestine, where it had to mediate between Jewish and Arab interests. In December 1941, the Struma, a ship carrying 769 Jewish refugees, left the Romanian port of Constantsa hoping to reach Palestine. Towed into Istanbul harbour when its engines failed, it became the subject of diplomatic discussions between Britain and Turkey. Britain's chief concern was to discourage what it regarded as an undesirable traffic, and it proposed that the ship be returned to Romania. After ten weeks of wrangling the Struma was towed out to sea, its engines still disabled, where it was sunk by a Soviet submarine. There was one survivor.
The prisoners are divided into three classifications, each treated differently. The first class is picked at random. These men act as firemen, and their only routine consists of some drilling. The second class is made up of the majority of the prisoners, who receive the treatment outlined above. The third class is composed of leading Communists and all the Jews. This class performs the hardest work on the smallest rations. They receive no sheets to cover their straw sacks. For a long time they were confined to dilapidated barracks where on rainy days the water would stand six inches deep on the floor. They are beaten more than the other prisoners, and nearly all of the murders are perpetrated on members of this class. Even within the last-mentioned class, the Jews are segregated, because no Aryan is allowed to share sleeping accommodations with a Jew. The Jews are refused cigarettes, and the other prisoners are forbidden to converse with them. However, the solidarity among the prisoners makes it impossible to put this rule into effect: camaraderie between the Jews and the other confined men is very strong. The prisoners are allowed to write one letter, or postcard, a week, which has to be turned in to the authorities unsealed. Any remarks about the conditions at the camp means daily beatings and severe punishment in dark cells.
According to Marcus J. Smith, a US military doctor who was assigned to Dachau after it was liberated, there was an "experimental farm, the Plantage" just outside the concentration camp. Smith wrote in his book "The Harrowing of Hell" that "When the Reichsfuehrer SS (Himmler) inspected, he seemed particularly interested in the Plantage, discoursing enthusiastically on the medicinal value of herbs."
Immediately after liberation, West European Jews who survived the Holocaust generally returned to their countries of origin. Holocaust survivors who tried to return to their homes in Eastern Europe faced many more difficulties. The Nazi destruction in the East had been all-encompassing. Many survivors, particularly in Eastern Europe, continued to encounter antisemitism when they returned to their communities. In some places survivors who had returned home met with violent hostility. In Kielce, 42 Jews who had survived the Holocaust were killed by local Poles in a pogrom on July 4, 1946.
The first major camp to be encountered by Allied troops, Majdanek, was discovered by the advancing Soviets on 25 July 1944.[375] Treblinka, Sobibór, and Bełżec were never liberated, but were destroyed by the Germans in 1943.[376] Auschwitz was liberated, also by the Soviets, on 27 January 1945;[377] Buchenwald by the Americans on 11 April;[378] Bergen-Belsen by the British on 15 April;[379] Dachau by the Americans on 29 April;[380] Ravensbrück by the Soviets on 30 April;[381] and Mauthausen by the Americans on 5 May.[382] The Red Cross took control of Theresienstadt on 4 May, days before the Soviets arrived.[383][384]
After the evacuation process began in February 1942, there were only a few Jews left in any of the camps in Germany, including Dachau. On April 29, 1945 when Dachau was liberated, there were 2,539 Jews in the main camp, including 225 women, according to the US Army census. Most of them had arrived only weeks or even days before, after they were evacuated from the Dachau sub-camps, mainly the Kaufering camps near Landsberg am Lech, where they had been forced to work in building underground factories for the manufacture of Messerschmitt airplanes.
On Wednesday the first concentration camp is to be opened in Dachau with an accommodation for 5000 people. 'All Communists and—where necessary—Reichsbanner and Social Democratic functionaries who endanger state security are to be concentrated here, as in the long run it is not possible to keep individual functionaries in the state prisons without overburdening these prisons, and on the other hand these people cannot be released because attempts have shown that they persist in their efforts to agitate and organize as soon as they are released.[48]

The Holocaust was the systematic, bureaucratic, state-sponsored persecution and murder of six million Jews by the Nazi regime and its collaborators. Holocaust is a word of Greek origin meaning "sacrifice by fire." The Nazis, who came to power in Germany in January 1933, believed that Germans were "racially superior" and that the Jews, deemed "inferior," were an alien threat to the so-called German racial community.

A training center for SS concentration camp guards, Dachau’s organization and routine became the model for all Nazi concentration camps. A new crematorium area was constructed in 1942 to dispose of the increasing number of casualties of typhoid, starvation, and executions. Dachau’s prisoners were used as subjects of medical experiments and hundreds of prisoners died or were permanently crippled as a result of these experiments.
SS-Hauptsturmführer Adolf Haas became the first commandant of the Bergen-Belsen camp in the spring of 1943; SS-Hauptsturmführer Josef Kramer replaced him in December 1944. The number of SS functionaries in Bergen-Belsen varied over the course of the camp's existence. The SS succeeded in destroying many of the camp's files, including those on personnel.
At the same time this little boy miraculously survived the same camp, Bergen-Belsen! More than any other photos, this famous photograph captures the essence of the horrors of Holocaust: Warsaw 1943, a little Jewish boy dressed in short trousers and a cap, raises his arms in surrender with lowered eyes, as a Nazi soldier trains his machine gun on him. 
Most of the regular SS guards and the administrative staff had fled from the camp the next day and there was no one left to oversee the burial of the bodies. No precise figures are available, but the train had started out with approximately 4,500 to 6,000 prisoners on board and between 1,300 and 2,600 had made it to Dachau still alive. Some of the dead had been buried along the way, or left in rows alongside the tracks. The gruesome sight of the death train, with some of the corpses in the open cars riddled by bullets, so affected the young soldiers of the 45th Thunderbird Division that they executed Waffen-SS soldiers stationed at the Dachau garrison after they had surrendered.
Antisemitism, the new racist version of the old Jew-hatred, viewed the Jews as not simply a religious group but as members of a 'Semitic race', which strove to dominate its 'Aryan' rivals. Among the leading ideologues of this theory were a French aristocrat, the Comte Joseph de Gobineau, and an Englishman, Houston Stewart Chamberlain. Antisemitism proved a convenient glue for conspiracy theories - since Jews were involved in all sorts of ventures and political movements, they could be accused of manipulating all of them behind the scenes. Thus Jews were held responsible for Communism and capitalism, liberalism, socialism, moral decline, revolutions, wars, plagues and economic crises. As the Jews had once been demonised in medieval Europe, so the new antisemites (including many Christians) found new, secular ways of demonising them.

After attending a series of trade schools in Brno and marrying Emilie Pelzl in 1928, Schindler held a variety of jobs, including working in his father's farm machinery business in Svitavy, opening a driving school in Sumperk, and selling government property in Brno. He also served in the Czechoslovak army and in 1938 attained the rank of lance corporal in the reserves. Schindler began working with the Amt Auslands/Abwehr (Office of the Military Foreign Intelligence) of the German Armed Forces in 1936. In February 1939, five months after the German annexation of the Sudetenland, he joined the Nazi Party. An opportunist businessman with a taste for the finer things in life, he seemed an unlikely candidate to become a wartime rescuer. During World War II, Schindler would rescue more than 1,000 Jews from deportation to Auschwitz, Nazi Germany's largest camp complex.
On May 5, 1945, Dutch resistance fighter Pim Boellaard was interviewed about his ordeal during his three years of captivity. As a resistance fighter, who continued to fight after the surrender of the Netherlands, he did not have the same protection as a POW under the Geneva Convention of 1929. He was one of 60 Dutch Nacht und Nebel prisoners who were transferred from the Natzweiler camp to Dachau in September 1944. Click here to see the video of his interview. Boellaard was a member of the International Committee of Dachau, representing approximately 500 Dutch prisoners at Dachau.

When British and Canadian troops finally entered they found over 13,000 unburied bodies and (including the satellite camps) around 60,000 inmates, most acutely sick and starving. The prisoners had been without food or water for days before the Allied arrival, partially due to allied bombing. Immediately before and after liberation, prisoners were dying at around 500 per day, mostly from typhus.[18] The scenes that greeted British troops were described by the BBC's Richard Dimbleby, who accompanied them:
