Throughout the summer of 1945, the International Committee of the Red Cross (ICRC) was prevented from visiting prisoners in any of the Allies' "Rheinwiesenlager". Visits were only started in the autumn of 1945, at a time when most camps had closed or were closing. The Red Cross was granted permission to send delegations to visit camps in the French and UK occupation zones. On 4 February 1946 the Red Cross was allowed to send relief to those in the U.S. run occupation zone. The International Red Cross website states "The quantities received by the ICRC for these captives remained very small, however. 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."
