As agreed by the Allies at the Yalta conference Germans were used as forced labor as part of the reparations to be extracted. By 1947 it is estimated that 400,000 Germans (both civilians and POWs) were being used as forced labor by the U.S., France, the UK and the Soviet Union. German prisoners were for example forced to clear minefields in France and the Low Countries. By December 1945 it was estimated by French authorities that 2,000 German prisoners were being killed or injured each month in accidents. In Norway the last available casualty record, from 29 August 1945, shows that by that time a total of 275 German soldiers died while clearing mines, while 392 had been injured.
