Another Polish courier, Jan Karski, reached the west in November 1942, carrying messages from Jewish leaders in Poland. He had himself witnessed the conditions in the Warsaw ghetto and in what he believed to be the Belzec death camp, and was eager to inform the world. Karski saw the British foreign secretary, Anthony Eden, and US President Roosevelt, but they seemed to be more interested in military intelligence than in atrocity stories. Partly as a result of Karski's mission, however, the Allies agreed to a joint declaration, read to the British Parliament on 17 December, which acknowledged Nazi war crimes and threatened punishment for the perpetrators. Subsequently millions of leaflets were dropped in the course of bombing raids on German cities to inform Germans of the facts, but these had little or no effect.
The first thing that visitors are told by their tour guides at Dachau is that the "Arbeit Macht Frei" sign was put up to taunt the prisoners who had no chance of being set free because the policy of the Dachau camp was extermination through work. Actually, the Arbeit Macht Frei sign was only put on Class 1 camps where prisoners had a good chance of being released. Buchenwald was a Class II camp where the sign on the gate said "Jedem das Seine," which means "To each his own." Mauthausen was a Class III camp where the prisoners were designated "Return unwanted" and there was no sign at all.
Of course, over time, we received help from outside. But we laid the foundation for this new community, we built it and ran it ourselves. We received food and books from outside, but we did the work and we can be proud of our efforts, Those who survived will always remember April 15, 1945 as their second birthday - in many ways more important than their first."5

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..."
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.
To the Nazi regime, there would have been no doubt that a war against Bolshevism was implicitly a war against the Jewish population of the Soviet Union. A division of Hitler’s SS known as the Einsatzgruppen traveled behind the German army and acted as death squads, exterminating civilian populations in the most efficient way possible. During the early part of Operation Barbarossa these were frequently people who had fled the Nazi’s earlier invasion of Poland.
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.
In 1935 the Wehrmacht began to build a large military complex close to the village of Belsen, a part of the town of Bergen, in what was then the Province of Hanover.[1] This became the largest military training area in Germany of the time and was used for armoured vehicle training.[1] The barracks were finished in 1937. The camp has been in continuous operation since then and is today known as Bergen-Hohne Training Area. It is used by the NATO armed forces.
