Between 1941 and 1945 the Axis powers took about 5.7 million Soviet prisoners. About one million of them were released during the war, in that their status changed but they remained under German authority. A little over 500,000 either escaped or were liberated by the Red Army. Some 930,000 more were found alive in camps after the war. The remaining 3.3 million prisoners (57.5% of the total captured) died during their captivity. Between the launching of Operation Barbarossa in the summer of 1941 and the following spring, 2.8 million of the 3.2 million Soviet prisoners taken died while in German hands. According to Russian military historian General Grigoriy Krivosheyev, the Axis powers took 4.6 million Soviet prisoners, of whom 1.8 million were found alive in camps after the war and 318,770 were released by the Axis during the war and were then drafted into the Soviet armed forces again. By comparison, 8,348 Western Allied prisoners died in German camps during 1939–45 (3.5% of the 232,000 total).
