Norman Naimark writes in "The Russians in Germany: A History of the Soviet Zone of Occupation, 1945–1949." that although the exact number of women and girls who were raped by members of the Red Army in the months preceding and years following the capitulation will never be known, their numbers are likely in the hundreds of thousands, quite possibly as high as the 2,000,000 victims estimate made by Barbara Johr, in "Befreier und Befreite". Many of these victims were raped repeatedly. Naimark states that not only had each victim to carry the trauma with her for the rest of her days, it inflicted a massive collective trauma on the East German nation (the German Democratic Republic).
