A Terrible Revenge: The Ethnic Cleansing of the East European Germans, 1944–1950 is a 1994 non-fiction book written by Cuban-born American lawyer Alfred-Maurice de Zayas, former research fellow at MPG in Heidelberg, Germany. The work is based on a collection of testimonials from German civilians and Wehrmacht military personnel; and devoted to the expulsion of Germans after World War II from states previously occupied by Nazi Germany. It includes as well selected interviews with British and American politicians who participated at the Potsdam Conference, including Robert Murphy, Geoffrey Harrison (drafter of article XIII of the Potsdam Protocol), and Denis Allen (drafter of article IX on the provisional post-war borders). The book attempts to describe the crimes committed against the German nation by the Soviet Union, Poland, Czechoslovakia, Hungary and Yugoslavia at the end of World War II – as perceived by the expellees themselves and settlers brought in Heim ins Reich (Home into the Empire) from the east. The author begins with the history of German settlement in Central and Eastern Europe since the 12th century, the impact of the Treaty of Versailles on German minorities in Poland and Czechoslovakia, the failure of the League of Nations system of minority protection, the outbreak of World War II and selected crimes committed by the Nazis, followed by the story of refugees from the former Eastern parts of Germany (Silesia, East Prussia, Pomerania, East Brandenburg), as well as the fate of German minorities in Czechoslovakia, Hungary, Poland, Romania, Yugoslavia and the Soviet Union. In the book, de Zayas claims that approximately two million Germans died during the post period of 1944–1949, although his claim does not withstand scrutiny. Most recent research on the subject has put the number at around half a million. Printing history The book originated as a script for a television documentary by the Bavarian Broadcasting. It was a popular rendition of the author's monography on the expulsions called the Nemesis at Potsdam (). This shorter introduction to the subject was published in German as Anmerkungen zur Vertreibung der Deutschen aus dem Osten (4 editions during 1986–1996, Kohlhammer Verlag, Stuttgart, ), first printed in English under the title of The German Expellees: Victims in War and Peace (St. Martin's Press, New York, 1993, Macmillan, London). The new, 1994 English title, included the then neologism "ethnic cleansing", used at that time in relation to the crimes committed by Serbs in
