After the surrender of Germany in May 1945, the POW status of the German prisoners was in many cases maintained, and they were for several years used as forced labour in countries such as the UK and France. Many died when forced to clear minefields in Norway, France etc.; "by September 1945 it was estimated by the French authorities that two thousand prisoners were being maimed and killed each month in accidents"
In 1946 the UK had more than 400,000 German prisoners, many had been transferred from POW camps in the US and Canada. Many of these were for over three years after the German surrender used as forced labour, as a form of "reparations". "The POWs referred to themselves as 'slave labour', with some justice." Their emotional state was worsened "from the anxiety and hope of the first half of 1946 to the depression and nihilism of 1948." A public debate ensued in the UK, where words such as "forced labour", "slaves", "slave labour" were increasingly used in the media and in the House of Commons. In 1947 the Ministry of agriculture argued against rapid repatriation of working German prisoners, since by then they made up 25 percent of the land workforce, and they wanted to use them also in 1948.
The "London Cage", a MI19 prisoner of war facility in the UK used for interrogating prisoners before they were sent to prison camps during and immediately after World War II, was subject to allegations of torture.
After the German surrender, the International Red Cross was prohibited from providing aid such as food or visiting prisoner camps in Germany. However, after making approaches to the Allies in the autumn of 1945 it was allowed to investigate the camps in the British and French occupation zones of Germany, as well as to provide relief to the prisoners held there. On February 4, 1946, the Red Cross was permitted to visit and assist prisoners also in the US occupation zone of Germany, although only with very small quantities of food. "During their visits, the delegates observed that German prisoners of war were often detained in appalling conditions. They drew the attention of the authorities to this fact, and gradually succeeded in getting some improvements made".
The Allies also shipped POWs between them, with for example 6,000 German officers transferred from Western Allied camps to the Sachsenhausen concentration camp that now was under Soviet Union administration. The US also shipped 740,000 German POWs as forced labourers to France from where newspaper reports told of very bad treatment. Judge Robert H. Jackson, Chief US prosecutor in the Nuremberg trials, in October 1945 told US President Harry S. Truman that the Allies themselves:
"have done or are doing some of the very things we are prosecuting the Germans for. The French are so violating the Geneva Convention in the treatment of prisoners of war that our command is taking back prisoners sent to them. We are prosecuting plunder and our Allies are practicing it."
