^ Jump up to: a b Eberhard Jäckel (Die Zeit, 1986): "Ich behaupte ... daß der nationalsozialistische Mord an den Juden deswegen einzigartig war, weil noch nie zuvor ein Staat mit der Autorität seines verantwortlichen Führers beschlossen und angekündigt hatte, eine bestimmte Menschengruppe einschließlich der Alten, der Frauen, der Kinder und der Säuglinge möglichst restlos zu töten, und diesen Beschluß mit allen nur möglichen staatlichen Machtmitteln in die Tat umsetzte." ("I maintain ... that the National Socialist killing of the Jews was unique in that never before had a state with the authority of its leader decided and announced that a specific group of humans, including the elderly, the women, the children and the infants, would be killed as quickly as possible, and then carried out this resolution using every possible means of state power.")
By the end of September, the SS had started to develop plans to deport Jews to newly invaded Poland: the first steps towards the systematic murder that would follow. In Poland itself, thousands of Poles and Jews were rounded up and shot, early indications of the systematic murder that would follow. Alongside this, Hitler approved a new programme of euthanasia to exterminate the handicapped and mentally ill.
The Nazis also used Dachau prisoners as subjects in brutal medical experiments. For example, inmates were obligated to be guinea pigs in a series of tests to determine the feasibility of reviving individuals immersed in freezing water. For hours at a time, prisoners were forcibly submerged in tanks filled with ice water. Some prisoners died during the process.
During this forced march anyone who could not keep up were shot, and many others died from hunger, cold, or exhaustion. At the beginning of May 1945, American troops overtook the remnants of these marching prisoners, left unguarded by SS who had fled. After the war, it was revealed that plans had existed to kill all the inmates by bombs and poison.
