In the postwar years, the camp continued in use. From 1945 through 1948, the camp was used by the Allies as a prison for SS officers awaiting trial. After 1948, when hundreds of thousands of ethnic Germans were expelled from eastern Europe, it held Germans from Czechoslovakia until they could be resettled. It also served as a military base for the United States, which maintained forces in the country. It was closed in 1960. At the insistence of survivors, various memorials have been constructed and installed here.:138
As Allied forces advanced toward Germany, the Germans began to more prisoners from concentration camps near the front to prevent the liberation of large numbers of prisoners. Transports from the evacuated camps arrived continuously at Dachau, resulting in a dramatic deterioration of conditions. After days of travel, with little or no food or water, the prisoners arrived weak and exhausted, near death. Typhus epidemics became a serious problem due to overcrowding, poor sanitary conditions, and the weakened state of the prisoners.
In 1944, Josiah DuBois, Jr. wrote a memorandum to then-Secretary of the Treasury Henry Morgenthau, Jr. entitled “Report to the Secretary on the Acquiescence of This Government in the Murder of the Jews”, which condemned the bureaucratic interference of U.S. State Department policies in obstructing the evacuation of Holocaust Refugees from Romania and Occupied France. The Report would spur the Roosevelt administration to create the War Refugee Board later that year.
On 15 September 1935, the Reichstag passed the Reich Citizenship Law and the Law for the Protection of German Blood and German Honor, known as the Nuremberg Laws. The former said that only those of "German or kindred blood" could be citizens. Anyone with three or more Jewish grandparents was classified as a Jew. The second law said: "Marriages between Jews and subjects of the state of German or related blood are forbidden." Sexual relationships between them were also criminalized; Jews were not allowed to employ German women under the age of 45 in their homes. The laws referred to Jews but applied equally to the Roma and black Germans.
On April 29, 1945, SS 2nd Lt. Heinrich Wicker surrendered the camp to the 42nd Rainbow Division of the US Seventh Army, which had found the camp on its way to take the city of Munich, 18 kilometers to the south. Accompanied by Red Cross representative Victor Maurer, 2nd Lt. Wicker surrendered the Dachau concentration camp to Brigadier General Henning Linden, commander of the 42nd Rainbow Division, under a white flag of truce. The 45th Thunderbird Division of the US Seventh Army also participated in the liberation of Dachau, arriving at the nearby SS garrison before the 42nd Division approached the installations's main entrance on the south side of the Dachau complex where 2nd Lt. Wicker was waiting to surrender the camp.
In her book Five Chimneys the Holocaust survivor Olga Lengyel later recalled the SS troops in fits of destructive insanity, blindly beating the sick women, kicking the pregnant: 'Kramer himself had lost his calm. A strange gleam lurked in his small eyes, and he worked like a madman. I saw hin throw himself at one unfortunate woman and with a single stroke of his truncheon shatter her skull ..'
In August 1944, a new section was created and this became the so-called "women's camp". By November 1944 this camp received around 9,000 women and young girls. Most of those who were able to work stayed only for a short while and were then sent on to other concentration camps or slave-labour camps. The first women interned there were Poles, arrested after the failed Warsaw Uprising. Others were Jewish women from Poland or Hungary, transferred from Auschwitz. Among those who never left Bergen-Belsen were Margot and Anne Frank, who died there in February or March 1945.
