Two days after liberation, the International Camp Committee passed control of the camp over to the U.S. Army. Despite emergency medical care, hundreds of former inmates died in the Displaced Persons Camp Buchenwald, as the camp was now called. The Americans confronted the population of Weimar with the crimes committed and opened Buchenwald for international delegations. Films and photographs of the camp spread across the world. The first memorial ceremony for those who died in the camp took place on April 19, 1945. Survivors read an oath of commitment to a world of peace and freedom, the "Oath of Buchenwald." While still in the camp, former inmates drew up initial documents for the creation of a democratic Germany as well as the "Manifesto of the Democratic Socialists of the former Buchenwald Concentration Camp." Survivors left the camp in groups through August. The U.S. troops had withdrawn from Thuringia in July, handing the camp over to the Soviet military administration.
