that this division had come about when "the Gestapo arrived one day without warning and decreed that one-third of the camp would belong to the Serbian authorities, and the rest they took for their prisoners". Initially the Gestapo and Serbian State Guard jointly guarded the camp, but this was later delegated to the Serbian State Guard alone. While Vujković was the administrator of the camp, he and his staff were at all times subject to the supervision of the Gestapo. The Germans often took decisions without reference to Vujković and his staff, but the Serbian staff were required to obtain approval from the Gestapo for nearly all actions they took.
