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 4 February 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".
