This and the rest of his evidence Mr. Le Drieullenac gave in a matter of fact way. This was the first time Kramer and his associates had faced one of the survivors of their camp, but for the first hour or so the Jersey man did not even look at them. Then, during the intervals for the translation of his evidence into German and Polish, he began looking at them with what seemed to be a puzzled air as if trying to find a link between his dreadful experience and the three rows of men and women in the dock and as if trying to realise that these were the people who had been the rulers of the camp where he had seen his best friend, a French colonel, dragged off to the burial pit to be thrown in while still alive.

Dachau was the first and most important camp at which German doctors and scientists set up laboratories using inmates as involuntary guinea pigs for such experiments as determining the effects on human beings of sudden increases and decreases in atmospheric pressure, studying the effects of freezing on warm-blooded creatures, infecting prisoners with malaria and treating them with various drugs with unknown effects, and testing the effects of drinking seawater or going without food or water. Continued throughout World War II, such experiments and the harsh living conditions made Dachau one of the most notorious of camps. After the war, the scientists and doctors from this and other camps were tried at Nürnberg in the “Doctors’ Trial”; seven were sentenced to death. (See Nürnberg trials.)

In the fall of that year the Płaszów work camp opened nearby, and by February 1943 it was under the command of the notoriously sadistic SS officer Amon Göth, who would be executed after the war. Capitalizing on the officer’s appetite for drink and other luxury items available mainly on the black market, Schindler cultivated his friendship by ensuring a constant stream of them to the villa from which he oversaw the camp. Schindler thus managed to prevail upon Göth to create a separate camp for his Jewish workers, where they were free of the abuses suffered at Płaszów. Though Schindler’s motivations prior to this point are unclear, many scholars interpret his efforts to extricate his workers from Płaszów as indication that his concern for them was not purely financial.
British troops guard Alex Pickowski, Camp Commandant of Dechau concentration camp  © The discovery of Belsen brought home the shocking truth about Nazi atrocities, but the facts had been known for some time. As early as the summer of 1941, British signals intelligence had intercepted and decoded radio messages from German police units co-operating with the Einsatzgruppen, and details of the killings of Jews were included in the monthly summaries that were sent to Churchill. Churchill responded with a speech on August 24 1941 in which he called the massacres 'a crime without a name' but erroneously identified the victims as 'Russian patriots defending their native soil'. Otherwise, these facts were not made public.
We continued to sing, to laugh, to dream, before the flames of the bonfires. We knew nothing as yet of the three hundred dead, twice the daily average of the last weeks before the liberation. We could not foresee that this figure would go even higher in the months to come and that our captivity was still far from being over. We could not admit that there were some among us who would never leave Dachau alive, as its inexorable law demanded. Dachau was to become in a way the symbol of all Europe, which believed itself freed, but was really only changing masters.
Lewis said that his comrades pushed cigarettes and sweets through the wire to the inmates who fell on them so ferociously that some were left dead on the ground, torn to pieces in the sordid scramble. The Hungarian Wehrmacht soldiers, who had been assigned to guard the camp during the transition, shot into the mob and killed numerous people. Lt. Lawrence Alsen, a British soldiers who was at the camp on the day of the liberation, told his son Niall after the war that "In some respects, the Hungarians were worse than the Germans."
From late 1944 to April, 1945, thousands of prisoners-many of them suffering from exposure and starvation from forced marches-flooded Bergen-Belsen from the East. Conditions, never good, deteriorated rapidly. Sanitary facilities were non-existent, food was scarce, the water supply grossly inadequate for the large influx of prisoners. A serious typhus epidemic erupted. In the first few months of 1945, up to 35,000 prisoners died, among them Margot and Anne Frank.

After 1945 the name was applied to the displaced persons camp established nearby, but it is most commonly associated with the concentration camp. From 1941 to 1945, almost 20,000 Soviet prisoners of war and a further 50,000 inmates died there.[3] Overcrowding, lack of food and poor sanitary conditions caused outbreaks of typhus, tuberculosis, typhoid fever and dysentery, leading to the deaths of more than 35,000 people in the first few months of 1945, shortly before and after the liberation.
