commandant of Sicherheitsdienst and Sicherheitspolizei in Warsaw, instead of being the main department of the camp's administration. Among the 208 identified members of the camp's administration, SS- Karl Leuckel was the director of the administrative department, SS-Oberscharführer was the Rapportführer and the person responsible for prisoner work management, while SS- and SS- were camp doctors. The camp's staff was subordinate to SS-WVHA, but it also was obliged to cooperate closely with the SS and police leader for the Warsaw District due to an agreement reached between the two SS institutions. The coordination was particularly strong during the pacification that happened at the turn of 1943/44, which was targeted at the Polish population of the capital. There were three concentration camp commandants () in the course of the camp's history: SS-Obersturmbannführer Wilhelm Göcke served until September 1943, when he was transferred to the newly created concentration camp in Kaunas, Lithuania; SS-Hauptsturmführer Nikolaus Herbet commanded the camp from September or October 1943 until his arrest in late April 1944; SS-Obersturmführer Friedrich Wilhelm Ruppert was appointed in May 1944 and dismissed in late June the same year. As for the Schutzhaftlagerführer, who was simultaneously the camp director and the chief of the guards, SS-Obersturmführer served in this role from KL Warschau's creation until his arrest in late April 1944, while SS-Unterscharführer occupied the position for the remainder of the camp's existence. The Warsaw concentration camp usually featured SS officers who were deemed to be low-value workers. The first two commandants exhibited incompetence and little interest in the functioning of the camp. Many of the Volksdeutsche were hardly able to speak German, while some were illiterate. Corruption was rampant and extended up to the apex of the camp's hierarchy, which Andreas Mix attributes to the fact that like the senior SS officers, the kapos were Germans, therefore, the SS officers frequently made illicit agreements with them. The irregularities were so numerous that SS authorities eventually intervened. Andreas Mix suggests that the trigger for such an intervention was an escape of a Reichsdeutsche prisoner. In late April 1944, Commandant Nikolaus Herbet, Schutzhaftlagerführer Wilhelm Härtel as well as Lagerälteste (camp supervisor) , were all arrested. The whole command of the camp was dissolved and almost all of its members were relieved of duty. By early May, the guards who were until then performing their duties in Warsaw were transported to Sachsenhausen and were replaced by personnel
