In July 1942 a new camp at Mährisch-Trübau, about 200 km (120 mi) to the south, was designated Oflag VIII-F, while the original camp was redesignated Oflag VIII F/Z, a sub-camp of Mährisch-Trübau.[1] The prisoners were transferred to other camps, though a small number stayed behind to carry out construction work as the site was adapted for the use of GEMA (Gesellschaft für und mechanische elektroakustische apparate) in developing radar systems.[3] The sub-camp was closed in June 1943.[1]
