Over the 12 years of use as a concentration camp, the Dachau administration recorded the intake of 206,206 prisoners and deaths of 31,951. Crematoria were constructed to dispose of the deceased. Visitors may now walk through the buildings and view the ovens used to cremate bodies, which hid the evidence of many deaths. It is claimed that in 1942, more than 3,166 prisoners in weakened condition were transported to Hartheim Castle near Linz, and were executed by poison gas because they were deemed unfit.[15]:137[21]
In her book Five Chimneys the Holocaust survivor Olga Lengyel later recalled the SS troops in fits of destructive insanity, blindly beating the sick women, kicking the pregnant: 'Kramer himself had lost his calm. A strange gleam lurked in his small eyes, and he worked like a madman. I saw hin throw himself at one unfortunate woman and with a single stroke of his truncheon shatter her skull ..' 
In the German parliament, the Nazi party, led by Adolf Hitler, gained popularity. The number of seats Nazis controlled in the parliament rose from 12 in 1928 to 230 in 1932, making them the largest political party. The strong showing guaranteed the Nazi party would need to be part of any political coalition. Believing he could check Hitler’s ambition, President Hindenburg reluctantly made Hitler the Chancellor of Germany on January 30, 1933.
Tens of thousands of Jews held in the eastern territories were marched towards the heart of Germany so they could not bear witness to the Allies. Aware that the world had been alerted to the horrors of the camps, the Nazis sought to destroy evidence. In June, Soviet forces liberated the first major camp, known as Majdanek, in Lublin, Poland. The Nazis had burned down the crematorium chimney but had failed to destroy the gas chambers and barracks. Only a few hundred inmates were still alive.
The prisoners of Dachau concentration camp originally were to serve as forced labor for a munition factory, and to expand the camp. It was used as a training center for SS guards and was a model for other concentration camps.[28] The camp was about 300 m × 600 m (1,000 ft × 2,000 ft) in rectangular shape. The prisoners' entrance was secured by an iron gate with the motto "Arbeit macht frei" ("Work will make you free"). This reflected Nazi propaganda, which trivialized concentration camps as labor and re-education camps, when in fact forced labor was used as a method of torture and murder.[29]

Beginning in 1943, a series of 123 sub-camps were set up near the Dachau main camp. The worst of these sub-camps were the 11 camps near Landsberg am Lech, which were named Kaufering I - XI; Kaufering was the name of the railroad station where the prisoners arrived by train. Beginning on June 18, 1944, Hungarian Jews from the death camp at Auschwitz-Birkenau were brought to the Kaufering camps to work on construction of underground factories where airplanes were to be built.
State of Health. The incidence of disease is very high here in proportion to the number of detainees. When you interviewed me on Dec. 1, 1944, at Oranienburg, you told me that Bergen-Belsen was to serve as a sick camp for all concentration camps in north Germany. The number of sick has greatly increased, particularly on account of the transports of detainees that have arrived from the East in recent times -- these transports have sometimes spent eight or fourteen days in open trucks ...

Construction on Baracke X began in July 1942, using the labor of the Catholic priests who were the only prisoners not forced to work in the factories at Dachau. The building was finished in 1943, but a sign that was put in the gas chamber in 1965 inexplicably informed tourists that this room was never used for gassing people. By May 2003, the sign was gone and a poster on the wall of the undressing room next to the gas chamber said that the gas chamber "could have been used" to kill prisoners.
The 15 men present at Wannsee included Adolf Eichmann (head of Jewish affairs for the RSHA and the man who organized the deportation of Jews), Heinrich Müller (head of the Gestapo), and other party leaders and department heads.[256] Thirty copies of the minutes were made. Copy no. 16 was found by American prosecutors in March 1947 in a German Foreign Office folder.[263] Written by Eichmann and stamped "Top Secret", the minutes were written in "euphemistic language" on Heydrich's instructions, according to Eichmann's later testimony.[264] The conference had several purposes. Discussing plans for a "final solution to the Jewish question" ("Endlösung der Judenfrage"), and a "final solution to the Jewish question in Europe" ("Endlösung der europäischen Judenfrage"),[256] it was intended to share information and responsibility, coordinate efforts and policies ("Parallelisierung der Linienführung"), and ensure that authority rested with Heydrich. There was also discussion about whether to include the German Mischlinge (half-Jews).[265] Heydrich told the meeting: "Another possible solution of the problem has now taken the place of emigration, i.e. the evacuation of the Jews to the East, provided that the Fuehrer gives the appropriate approval in advance."[256] He continued:
Some 28,000 prisoners died of disease and other causes in the weeks after the British army liberated the camp on April 15, 1945. The British were forced to bury thousands of corpses in mass graves hastily excavated on the site. Bergen-Belsen was the first major Nazi concentration camp to be liberated by the Western Allies, and its horrors gained instant notoriety. Forty-eight members of the camp staff were tried and 11 of them, including SS commandant Josef Kramer, the “Beast of Belsen,” were sentenced to death by a British military court and hanged. After the war, Bergen-Belsen became the largest displaced-person camp in Germany. Most of its residents later immigrated to Israel.
On March 7, 1933, an important law was passed by the newly-elected German Congress, which called for all high-level government officials in the German states to be appointed by the Nazis and for all state government positions to be supervised by the Nazis in the event of an emergency. Germany was already in an emergency situation and Article 48 of the German Constitution had already been invoked. Under this new law, Heinrich Himmler was appointed the acting Chief of Police in Munich, although his real job was Reichsführer-SS, the leader of Hitler's elite private Army.

The twin goals of racial purity and spatial expansion were the core of Hitler’s worldview, and from 1933 onward they would combine to form the driving force behind his foreign and domestic policy. At first, the Nazis reserved their harshest persecution for political opponents such as Communists or Social Democrats. The first official concentration camp opened at Dachau (near Munich) in March 1933, and many of the first prisoners sent there were Communists.

The ramp appeared to lead up to the crematorium ovens. I am not surprised that the commandant and the guards were not charged with gassing prisoners because the evidence had been destroyed by the British, but that was academic because they had enough evidence to hang Kramer and Grese a hundred times over. As my Dad's colonel said to him: "They'll have a legal trial and a legal hanging..."

Many of the former SS staff who survived the typhus epidemic were tried by the British at the Belsen trial. Over the period in which Bergen-Belsen operated as a concentration camp, at least 480 people had worked as guards or members of the commandant's staff, including around 45 women.[27] From September 17 to November 17, 1945, 45 of those were tried by a military tribunal in Lüneburg. They included former commandant Josef Kramer, 16 other SS male members, 16 female SS guards and 12 former kapos (one of whom became ill during the trial).[28] Among them were Irma Grese, Elisabeth Volkenrath, Hertha Ehlert, Ilse Lothe [de], Johanna Bormann and Fritz Klein. Many of the defendants were not just charged with crimes committed at Belsen but also earlier ones at Auschwitz. Their activities at other concentration camps such as Mittelbau-Dora, Ravensbrück, Neuengamme, the Gross Rosen subcamps at Neusalz and Langenleuba, and the Mittelbau-Dora subcamp at Gross Werther were not subject of the trial. It was based on British military law and the charges were thus limited to war crimes.[28] Substantial media coverage of the trial provided the German and international public with detailed information on the mass killings at Belsen as well as on the gas chambers of Auschwitz-Birkenau.[28]
A young man sits on an overturned stool next to a burnt body in the Thekla camp outside Leipzig, in April of 1945, after the US troops entered Leipzig April 18. On the 18th of April, the workers of the Thekla plane factory were locked in an isolated building of the factory by the Germans and burned alive by incendiary bombs. About 300 prisoners died. Those who managed to escape died on the barbed wire or were executed by the Hitler youth movement, according to a US captain's report. #
Upon liberating Bergen Belsen, British soldiers discovered the true nature of the Nazi Third Reich. Bergen Belsen had reached its lowest point about three weeks before liberation. Typhus was raging and about 1000 inmates died every day from this epidemic. There was no running water and rations were down to half a pint of soup a day and bread only three times a week. Although the British soldiers had heard about Nazi atrocities, nothing prepared them for what they saw. Richard Dimbleby of the BBC (British Broadcasting Corporation), who visited Bergen Belsen a few days after liberation, broke down several times when he tried to record his first impressions of the camp. On April 19, 1945, the BBC broadcasted his report and a stunned world learned what the inmates of Bergen Belsen had gone through, and what the British soldiers had witnessed a few days before. It took the British soldiers some time to realize that the former prisoners at Bergen Belsen needed easily digested food such as rice, biscuits and fresh milk. Thousands of prisoners died after liberation because they could not get to the food that the British provided, or because they ate too much, or because they could not digest the food that was available. 
Peter Hayes (How Was It Possible? A Holocaust Reader, 2015): "The Holocaust, the Nazi attempt to eradicate the Jews of Europe, has come to be regarded as the emblematic event of Twentieth Century ... Hitler's ideology depicted the Jews as uniquely dangerous to Germany and therefore uniquely destined to disappear completely from the Reich and all territories subordinate to it. The threat posted by supposedly corrupting but generally powerless Sinti and Roma was far less, and therefore addressed inconsistently in the Nazi realm. Gay men were defined as a problem only if they were German or having sex with Germans or having sex with Germans and considered 'curable' in most cases. ... Germany's murderous intent toward the handicapped inhabitants of European mental institutions ... was more comprehensive ... but here, too, implementation was uneven and life-saving exceptions permitted, especially in Western Europe. Not only were some Slavs—Slovaks, Croats, Bulgarians, some Ukrainians—allotted a favored place in Hitler's New Order, but the fate of most of the other Slavs the Nazis derided as sub-humans ... consisted of enslavement and gradual attrition, not the prompt massacre meted out to the Jews after 1941."[20]
In 1946, Belsen served as the largest DP camp in Europe for more than 12,000 Jews; it was the only exclusively Jewish camp in the British zone of Germany. The refugees formed a camp committee within three days of liberation. Political, cultural and religious activities were organized by the committee, such as searching for relatives and spiritual rehabilitation. Jewish family life was renewed, more than twenty marriages were performed daily during the first few months. More than 2,000 children were born to survivors. An elementary school was founded in July 1945 and, by 1948, 340 students attended the school. In December 1945, a high school was started and was partly staffed by the Jewish brigade. A kindergarten, orphanage, yeshiva and religious school were also formed. ORT sponsored a vocational training school. The DPs also wrote the main Jewish newspaper, Unzer Shtimme (Our Voice), in the British zone.

In 1935 Schindler joined the pro-Nazi Sudeten German Party (Sudetendeutsche Partei; SdP) and the next year began collecting counterintelligence for the Abwehr, the German military intelligence agency. In 1938 he was arrested by Czechoslovak authorities on charges of espionage and sentenced to death. After the annexation of the Sudetenland by Germany late that year as part of the Munich Agreement, Schindler was pardoned by the Reich and rose through the ranks of the Abwehr. His application for membership in the Nazi Party—thought to have been submitted out of pragmatism rather than ideological affinity—was accepted in 1939. That year, on the heels of the German invasion and occupation of Poland, Schindler journeyed to Kraków, where he became active in the emerging black market. Thanks to the network of German contacts he had arranged through liberal bribes, he secured the lease of a formerly Jewish-owned enamelware factory. He renamed the facility Deutsche Emaillewaren-Fabrik Oskar Schindler (known as Emalia) and commenced production with a small staff. Three months later he had several hundred employees, seven of whom were Jewish. By 1942 nearly half of the workers at the expanded plant were Jewish. (Ostensibly “cheap labour,” Schindler paid their salaries to the SS.)
As some needed to point out, this is a fictionalized account of historical events and a genuine hero. Some historical persons were combined to make one character in the book and some time frames were condensed. Oskar Schindler was a deeply flawed man, brought to greatness by living through a time of horror in a position where he could make a small, but real difference. The condensations of those true events in this book are masterful. A great book!

Prisoners continued to die, in spite of the medical treatment provided by the Red Cross and the British Army. Nine thousand died in the first two weeks after the British arrived, and another 4000 died in May. The bodies were thrown into unmarked mass graves, even though the identities of these prisoners were known. Today none of the mass graves at Bergen-Belsen has a stone with the names of those who are buried there.
Treatment inside the concentration camps were horrible. Prisoners were given tiny rations of food and forced into physical labor. They often slept more than three to a bed without pillows or blankets, even in the winter months. In many concentration camps, Nazi doctors conducted medical experiments on prisoners against their will, in many cases killing the prisoners in the process.
Originally established as a prisoner of war camp, in 1943, parts of Bergenbelsen became a concentration camp. Initially it was an “exchange camp,” where Jewish hostages were held with the intention of exchanging them for German prisoners of war held overseas. The camp was later expanded to accommodate Jews from other concentration camps. It is also the location where writer Anne Frank passed away.

Außenlager Unterlüß-Altensothrieth (Tannenberglager) east of Bergen was in use from late August 1944 to April 13, 1945. It was located at Unterlüß, where the Rheinmetall-Borsig AG had a large test site. Up to 900 female Polish, Hungarian, Romanian, Yugoslavian and Czech Jews had to clear forest, do construction work or work in munitions production.[10]:204
