Ohrdruf concentration camp
Established in late 1944 in Ohrdruf near Gotha as the Ohrdruf forced labor camp (also "Ohrdruf-North"), a subcamp of the Buchenwald concentration camp. The prisoners were used to build underground tunnel and bunker facilities. In March 1945, the camp had 11,700 prisoners. On April 4, 1945, the Ohrdruf forced labor camp was the first concentration camp in which the U.S. Army found surviving prisoners who could give information about their fate. It was visited on April 12 by several U.S. generals—George S. Patton, Omar N. Bradley, and Dwight D. Eisenhower—and the visit had great influence on U.S. policy regarding defeated Germany.
