When the Second World War in Europe ended in May 1945, the United States military had custody of a staggering number of enemy prisoners of war: 4.3 million total world-wide, with more than 400,000 held in prison camps inside the domestic United States. German personnel represented the single largest group of prisoners. However not every soldier in German uniform who fell into American hands—whether through capture, surrender, or exchange of custody with another ally—was actually a German citizen. Between 1939 and 1945, tens of thousands of Frenchmen, Poles, Dutchmen, and Norwe-gians wound up in German uniform, either voluntarily or through coercion. Nearly a million Soviet citizens, ethnic Russians, Ukrainians, and Cossacks had served in the German military for a myriad of reasons, plus many more millions of captured Soviet soldiers held as prisoners of the Germans were now in American or British hands; it was they who would represent one of the thorniest problems among the former allies in the war’s aftermath.
Prisoner of war issues during WWII were at least notionally governed by the 1929 Geneva Convention Relative to the Treatment of Prisoners of War, but the conduct of Germany, Japan, and the Soviet Union demonstrated all too clearly the limitations of international conventions and laws of war. The Soviet Union was not a signatory to the 1929 Convention; Japan signed it but never ratified it; Germany was a full signatory. The legal distinction between them was largely irrelevant, because those three nations were categorically guilty of the worst treatment of the war was over. The end of the conflict precipitated one of the most controversial episodes related to international conventions on prisoners of war: the question of forced repatriation.
