By mid-1944 those Jewish communities within easy reach of the Nazi regime had been largely exterminated,[367] in proportions ranging from about 25 percent in France[368] to more than 90 percent in Poland.[369] On 5 May Himmler claimed in a speech that "the Jewish question has in general been solved in Germany and in the countries occupied by Germany".[370] As the Soviet armed forces advanced, the camps in eastern Poland were closed down, with surviving inmates shipped to camps closer to Germany.[371] Efforts were made to conceal evidence of what had happened. The gas chambers were dismantled, the crematoria dynamited, and the mass graves dug up and the corpses cremated.[372] Local commanders continued to kill Jews, and to shuttle them from camp to camp by forced "death marches".[373] Already sick after months or years of violence and starvation, some were marched to train stations and transported for days at a time without food or shelter in open freight cars, then forced to march again at the other end to the new camp. Others were marched the entire distance to the new camp. Those who lagged behind or fell were shot. Around 250,000 Jews died during these marches.[374]

Medical experiments were conducted at Dachau with Jews helplessly used in decompression and high altitude tests. Others were infected with malaria to test possible vaccines.13 In the twelve years Dachau was operational, more than 200,000 prisoners passed through the camp.13 Officially more than 30,000 died at Dachau but the actual number is thought to be much higher.13
Kramer's clear conscience is also suggested by the fact that he made no effort to save his life by fleeing, but instead calmly awaited the approaching British forces, naively confident of decent treatment. "When Belsen Camp was eventually taken over by the Allies," he later stated, "I was quite satisfied that I had done all I possibly could under the circumstances to remedy the conditions in the camp." /19
In 1944, Josiah DuBois, Jr. wrote a memorandum to then-Secretary of the Treasury Henry Morgenthau, Jr. entitled “Report to the Secretary on the Acquiescence of This Government in the Murder of the Jews”, which condemned the bureaucratic interference of U.S. State Department policies in obstructing the evacuation of Holocaust Refugees from Romania and Occupied France. The Report would spur the Roosevelt administration to create the War Refugee Board later that year.
After its defeat in World War I, Germany was humiliated by the Versailles Treaty, which reduced its prewar territory, drastically reduced its armed forces, demanded the recognition of its guilt for the war, and stipulated it pay reparations to the allied powers. With the German Empire destroyed, a new parliamentary government called the Weimar Republic was formed. The republic suffered from economic instability, which grew worse during the worldwide depression after the New York stock market crash in 1929. Massive inflation followed by very high unemployment heightened existing class and political differences and began to undermine the government.
As discrimination against Jews increased, German law required a legal definition of a Jew and an Aryan. Promulgated at the annual Nazi Party rally in Nürnberg on September 15, 1935, the Nürnberg Laws—the Law for the Protection of German Blood and German Honour and the Law of the Reich Citizen—became the centrepiece of anti-Jewish legislation and a precedent for defining and categorizing Jews in all German-controlled lands. Marriage and sexual relations between Jews and citizens of “German or kindred blood” were prohibited. Only “racial” Germans were entitled to civil and political rights. Jews were reduced to subjects of the state. The Nürnberg Laws formally divided Germans and Jews, yet neither the word German nor the word Jew was defined. That task was left to the bureaucracy. Two basic categories were established in November: Jews, those with at least three Jewish grandparents; and Mischlinge (“mongrels,” or “mixed breeds”), people with one or two Jewish grandparents. Thus, the definition of a Jew was primarily based not on the identity an individual affirmed or the religion he or she practiced but on his or her ancestry. Categorization was the first stage of destruction.
The Nazis brought their own strain of radical ruthlessness to these ideas. They glorified war and saw the uncompromising struggle for survival between nations and races as the engine of human progress. They rejected morality as a Jewish idea, which had corrupted and weakened the German people. They maintained that a great nation such as Germany had the right and duty to build an empire based on the subjugation of 'inferior races'. They looked eastwards to Poland and Russia (where, as it happened, the great majority of European Jews lived) for the territorial expansion of their 'living space' (Lebensraum).

The possible final remnant will, since it will undoubtedly consist of the most resistant portion, have to be treated accordingly because it is the product of natural selection and would, if released, act as the seed of a new Jewish revival (see the experience of history.) In the course of the practical execution of the final solution, Europe will be combed through from west to east. Germany proper, including the Protectorate of Bohemia and Moravia, will have to be handled first due to the housing problem and additional social and political necessities. The evacuated Jews will first be sent, group by group, to so-called transit ghettos, from which they will be transported to the East.[256]
Indelibly scarred by the savagery and suffering he confronted during World War II—in England during the Blitz; in war-torn Southeast Asia and Europe; and, especially, in Bergen-Belsen—George Rodger did not work as a war photographer again. He did, however, continue to travel and photograph around the world in the decades after the war—particularly in Africa, where he made some of his most celebrated pictures.
During the liberation of the sub-camps surrounding Dachau, advance scouts of the U.S. Army's 522nd Field Artillery Battalion, a segregated battalion consisting of Nisei, 2nd generation Japanese-Americans, liberated the 3,000 prisoners of the "Kaufering IV Hurlach"[85] slave labor camp.[86] Perisco describes an Office of Strategic Services (OSS) team (code name LUXE) leading Army Intelligence to a "Camp IV" on 29 April. "They found the camp afire and a stack of some four hundred bodies burning ... American soldiers then went into Landsberg and rounded up all the male civilians they could find and marched them out to the camp. The former commandant was forced to lie amidst a pile of corpses. The male population of Landsberg was then ordered to walk by, and ordered to spit on the commandant as they passed. The commandant was then turned over to a group of liberated camp survivors".[87] The 522nd's personnel later discovered the survivors of a death march[88] headed generally southwards from the Dachau main camp to Eurasburg, then eastwards towards the Austrian border on 2 May, just west of the town of Waakirchen.[89][90]
Dachau was never a camp that was specifically intended for murdering the Jews; the Nazi plan was to consolidate all the Jews into ghettos, from which they were later sent to the death camps. German Jews were sent to the Lodz ghetto in what is now Poland where they worked in factories until 1944; those who could no longer work were sent to the Chelmno death camp. In 1942, the Jews who were still living in Germany were sent to the Theresienstadt ghetto in what is now the Czech Republic and from there to the gas chambers in Auschwitz-Birkenau.
"Suddenly we were marched into Bergen Belsen, that's where we were taken. In Bergen Belsen it was absolutely the worst of them all. It was not blocks; not organized. It was in the streets. We were just thrown in there between the electric wires, and wherever you could go - you go, and wherever you want to sleep - you sleep. No food. Only once or twice a week they were handing out some of that horrible grass soup."1
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
