According to mainstream historiography, 170,000 to 250,000 Jews were exterminated at the SobibOr Camp, eastern Poland, in gas chambers between May 1942 and October 1943. The corpses were buried in mass graves and later incinerated on an open-air pyre. In this book, the orthodox version of what transpired at SobibOr is put under the microscope. It is shown that the traditional narrative of the camp's history is not based on solid evidence, but on the selective use of eyewitness testimonies, which in turn are riddled with contradictions and outright absurdities. All early witnesses, for example, report about murder with chlorine or an ominous black liquid, and almost all witnesses agree that the gas chambers had collapsible floors, which served to quickly remove the corpses after the deed into hollow spaces underneath. Engines were posited as a source of poison gas only after the war, and the stories about collapsible floors were relegated to oblivion by orthodox historians. For more than half a century, Holocaust historians made no attempts to muster material evidence for their claims about SobibOr. Only in 2000-2001 did Professor Andrzej Kola carry out an archeological survey at the former campsite. His findings are here presented in detail and revealed to have fatal implications for the extermination camp hypothesis. Also scrutinized is the basis of the mass-gassing allegations, namely the alleged National Socialist policy of extermination of the Jews. A large number of contemporary documents are brought forth which refute the Holocaust historians' claim that the "Final Solution" and "deportation to the east" were code words for mass murder. What emerges from the analysis is the picture of SobibOr not as a "pure extermination camp," but as a transit camp from where Jews were deported to the occupied eastern territories.
