When asked, Schindler told that his metamorphosis during the war was sparked by the shocking immensity of the Final Solution. In his own words: "I hated the brutality, the sadism, and the insanity of Nazism. I just couldn't stand by and see people destroyed. I did what I could, what I had to do, what my conscience told me I must do. That's all there is to it. Really, nothing more."
On arrival at Belsen with his kommondo on the night of what he believes was April 5, he was placed in a hut which was in a state of filth and overcrowding which nobody in the outside world ever dreamed could exist before Belsen was discovered. The next morning, after a roll-call lasting from 3.30 to 9, he inspected the next hut, a long, low building. Looking through a hole where a window had been, he saw one or two bodies lying about in the water on the floor of what had been the wash-place. Looking through other windows he saw piles of bodies systematically stacked, each one’s head resting on the chest of the man or woman below. The whole building was full of corpses.

On 7 November 1938, Herschel Grynszpan, a Polish Jew, shot the German diplomat Ernst vom Rath in the German Embassy in Paris, in retaliation for the expulsion of his parents and siblings from Germany.[118][k] When vom Rath died on 9 November, the government used his death as a pretext to instigate a pogrom against the Jews throughout the Third Reich. The government claimed it was spontaneous, but in fact it had been ordered and planned by Hitler and Goebbels, although with no clear goals, according to David Cesarani; the result, he writes, was "murder, rape, looting, destruction of property, and terror on an unprecedented scale".[120][121]
In the view of Christian Gerlach, Hitler announced his decision to annihilate the Jews on or around 12 December 1941, probably on 12 December during a speech to the Gauleiters, part of the Nazi Party leadership.[259] This was one day after the German declaration of war against the United States, which followed the Japanese attack on Pearl Harbour on 7 December and the United States declaration of war on Japan on 8 December.[260] According to Deborah Dwork and Robert Jan van Pelt, Hitler had trusted American Jews, whom he assumed were all-powerful, to keep their government out of the war in the interests of German Jews. When America declared war, the Jews were blamed.[261] Joseph Goebbels, the Reich Minister of Propaganda, noted of Hitler's speech: "He warned the Jews that if they were to cause another world war, it would lead to their destruction. ... Now the world war has come. The destruction of the Jews must be its necessary consequence."[260][o]
Dachau, located ten miles north of Munich, Germany, was the first concentration camp built by the Nazis and served as a model for all later camps. By 1937, it held 13,260 prisoners, including German communists and social democrats as well as Jehovah’s Witnesses, Roma (Gypsies), and homosexuals. Dachau also served as the central camp for Christian religious prisoners.
Though at the time of liberation the death rate had peaked at 200 per day, after the liberation by U.S. forces the rate eventually fell to between 50 and 80 deaths per day. In addition to the direct abuse of the SS and the harsh conditions, people died from typhus epidemics and starvation. The number of inmates had peaked in 1944 with transports from evacuated camps in the east (such as Auschwitz), and the resulting overcrowding led to an increase in the death rate.[47]
He began by turning his factory into an official subcamp of a newly constructed labor camp at Plazów. For a time, it was a haven for about 500 Jews. Then, in the fall of 1944, the Nazis ordered both camps closed and all workers shipped to Auschwitz, a killing center. Schindler refused to let that happen. He put together a list of 1,100 men, women, and children that he claimed as his workers. He then used his money and influence to transport those workers to a new factory he was building at Brinnlitz, Czechoslovakia. When the Jewish women who worked in his factory were transported to Auschwitz by mistake, he accomplished the impossible: he managed to get the women back by offering Nazi officials a fortune in bribes.
Several books published after the war maintained that there was a gas chamber at Bergen-Belsen. For example, in a book entitled "Jews, God and History," Jewish historian Max Dimont mentioned gassings at Bergen-Belsen. Another book, entitled "A History of World War II" claimed that "In Belsen, Kramer kept an orchestra to play him Viennese music while he watched children torn from their mothers to be burned alive. Gas chambers disposed of thousands of persons daily." (Josef Kramer was the Commandant of Bergen-Belsen from 2 December 1944 until the camp was liberated.)
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]
