German historians Hans Henning Hahn and Eva Hahn published a detailed study of the flight and expulsions that is sharply critical of German accounts of the Cold War era. The Hahns regard the official German figure of 2 million deaths as an historical myth, lacking foundation. They place the ultimate blame for the mass flight and expulsion on the wartime policy of the Nazis in Eastern Europe. The Hahns maintain that most of the reported 473,013 deaths occurred during the Nazi organized flight and evacuation during the war, and the forced labor of Germans in the Soviet Union; they point out that there are 80,522 confirmed deaths in the postwar internment camps. They put the postwar losses in eastern Europe at a fraction of the total losses: Poland- 15,000 deaths from 1945 to 1949 in internment camps; Czechoslovakia- 15,000–30,000 dead, including 4,000–5,000 in internment camps and ca. 15,000 in the Prague uprising; Yugoslavia- 5,777 deliberate killings and 48,027 deaths in internment camps; Denmark- 17,209 dead in internment camps; Hungary and Romania - no postwar losses reported. The Hahns point out that the official 1958 figure of 273,000 deaths for Czechoslovakia was prepared by Alfred Bohmann, a former Nazi Party member who had served in the wartime SS. Bohmann was a journalist for an ultra-nationalist Sudeten-Deutsch newspaper in postwar West Germany. The Hahns believe the population figures of ethnic Germans for eastern Europe include German-speaking Jews killed in the Holocaust. They believe that the fate of German-speaking Jews in Eastern Europe deserves the attention of German historians.
