 The camp was soon renamed as the "Central Labor Camp" (COP) and the German inscription ""Arbeit macht frei"" ("Work makes (you) free") was replaced by Polish ""Praca uszlachetnia człowieka"" ("Work ennobles man").The prisoners mostly worked on the construction of Jaworzno power plant or in nearby factories and mines.All of them were interned in separate subcamps and were guarded by more than 300 soldiers and officers from the Internal Security Corps, aided by about a dozen civilian personnel.
