working German prisoners, since by then they made up 25 percent of the land workforce, and it wanted to continue having them work in the UK until 1948. The "London Cage", an MI19 prisoner of war facility in London used during and immediately after the war to interrogate prisoners before sending them to prison camps, was subject to allegations of torture. After the German surrender, the International Red Cross was prohibited from providing aid, such as food or prisoner visits, to POW camps in Germany. However, after making appeals to the Allies in the autumn of 1945, the Red Cross was allowed to investigate the camps in the British and French occupation zones of Germany, as well as providing relief to the prisoners held there. On 4 February 1946, the Red Cross was also permitted to visit and assist prisoners 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". POWs were also transferred among the Allies, with for example 6,000 German officers transferred from Western Allied camps to the Soviets and subsequently imprisoned in the Sachsenhausen concentration camp, at the time one of the NKVD special camps. Although the Soviet Union had not signed the Geneva Convention, the U.S. chose to hand over several hundred thousand German prisoners to the Soviet Union in May 1945 as a "gesture of friendship". U.S. forces also refused to accept the surrender of German troops attempting to surrender to them in Saxony and Bohemia, and handed them over to the Soviet Union instead. The United States handed over 740,000 German prisoners to France, which was a Geneva Convention signatory but which used them as forced labourers. Newspapers reported that the POWs were being mistreated; Judge Robert H. Jackson, chief US prosecutor in the Nuremberg trials, told US President Harry S Truman in October 1945 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 practising it.The Legacy of Nuremberg PBS
