"From the beginning, the Nazis made no secret of their goal of creating a "Jew-free" Germany and Europe. One of the earliest methods was, indeed, forced emigration. But on November 10, 1941, precise instructions from Berlin to kill the Jews in his area were received by Higher SS and police leader, Friedrich Jeckeln from Berlin, stating, that pursuant to the Fuehrer's order, Jews would no longer be allowed "to emigrate", instead they would be "evacuated." In his October 4, 1943 speech to SS generals in Poznan, SS Chief, Heinrich Himmler, left no doubt as to the meaning of evacuation. "I am now referring to the evacuation of the Jews, the extermination of the Jewish people", he declared.
"Evacuation" had been a Nazi codeword for murder even earlier. In the Spring of 1940, 1,558 mental patients had been transferred from sanitoriums in Eastern Prussia for "evacuation" near the Soldau concentration camp. They were never heard from again. The Nazis attempted to hide their intentions by the use of codewords. "Resettlement" was commonly used to describe the deportation of Jews to the gas chambers, hence SS Major, Francke-Gricksch's 1943 report on Auschwitz in which he remarks that the camp's "resettlement furnaces" were capable of burning 10,000 bodies a day.
Despite the attempts at deception, Victor Brack, one of the chief architects of Hitler's "euthanasia" experiments testified to the war crimes tribunal at Nuremberg, that it was no secret among the Nazi hierarchy that "the Jews were to be exterminated."
