While these massacres were happening, the Nazis elsewhere were laying plans for an overall 'solution to the Jewish question'. Death camp operations began in December 1941 at Semlin in Serbia and Chelmno in Poland, where people were killed by exhaust fumes in specially modified vans, which were then driven to nearby sites where the bodies were plundered and burnt. 250,000 Jews were killed this way at Chelmno and 15,000 at Semlin.
Shipments of Jews to the camps had priority over anything but the army's needs on the German railways, and continued even in the face of the increasingly dire military situation at the end of 1942. Army leaders and economic managers complained about this diversion of resources and the killing of skilled Jewish workers, but Nazi leaders rated ideological imperatives above economic considerations.
Relying on a surveying device known as a total station—the tripod-mounted optical instrument employed by construction and road crews—Reeder set about measuring minute elevation changes across the land, searching for subtle gradations and anomalies. He zeroed in on a hummock that looked like the earthen side of a bunker, long since overgrown with moss and foliage, and roughly 100 feet away, a telltale dip in the earth.
The Nazi invasion of the Soviet Union codenamed Operation Barbarossa, which commenced on 22 June 1941, set in motion a "war of destruction" which quickly opened the door to systematic mass murder of European Jews. For Hitler, Bolshevism was merely "the most recent and most nefarious manifestation of the eternal Jewish threat". On 3 March 1941, Wehrmacht Joint Operations Staff Chief Alfred Jodl repeated Hitler's declaration that the "Jewish-Bolshevik intelligentsia would have to be eliminated" and that the forthcoming war would be a confrontation between two completely opposing cultures. In May 1941, Gestapo leader Heinrich Müller wrote a preamble to the new law limiting the jurisdiction of military courts in prosecuting troops for criminal actions because: "This time, the troops will encounter an especially dangerous element from the civilian population, and therefore, have the right and obligation to secure themselves."
“I am marshalling my last remaining strength in order to die peacefully as one who will not surrender and who will not ask for forgiveness. The historical fact that Israel became the leading social political superpower in the 19th century lies before us. We have amongst us a flexible, tenacious, intelligent foreign tribe that knows how to bring abstract reality into play in many different ways. Not individual Jews but the Jewish spirit and Jewish consciousness have overpowered the world. All this is the consequence of a cultural history so unique in its way, so grand that every day polemic can achieve nothing against it. With the entire force of its armies the proud Roman Empire did not achieve that which Semitism has achieved in the West and particularly in Germany.”
“I’ve offered three possibilities” to the museum, Freund said. The first was to try to partially excavate one section of the tunnel and protect it with climate-controlling plexiglass walls. Alternatively, a re-creation could be built, as had been done with the recently finished facsimile of King Tutankhamun’s tomb, in the Valley of the Kings, in Egypt. The last option, Freund allowed, was a “little futuristic”: Relying on the data from the scans, a 3-D film could be created so visitors could relive the experience of the escape.
The ideology of Nazism brought together elements of antisemitism, racial hygiene, and eugenics, and combined them with pan-Germanism and territorial expansionism with the goal of obtaining more Lebensraum (living space) for the Germanic people. Nazi Germany attempted to obtain this new territory by attacking Poland and the Soviet Union, intending to deport or kill the Jews and Slavs living there, who were considered by the Nazis to be inferior to the Aryan master race.
