In the twelve months preceding the end of the Second World War, the International Committee of the Red Cross and various voluntary organizations acting with the Red Cross, were able to dispatch food parcels to increasingly large numbers of concentration camp inmates in Germany and German-controlled territory. As Allied pressure on Germany increased during the last months of the war, the possibilities of sending large-scale relief into the camps prior to their liberation expanded dramatically. However, Allied blockade policy was so deeply entrenched that it was almost impossible for these possibilities to be fully exploited. Official relief agencies failed to convince Supreme Headquarters of the Allied Expeditionary Force (SHAEF) that improving the rations of the camp inmates would not strengthen the German working force but would alleviate the problems that SHAEF itself would confront when it liberated the camps shortly thereafter.
