The Gross-Rosen concentration camp located in Rogoźnica , Poland ( part of the German Silesia in World War II ) , was surrounded by a network of 97 satellite camps ( '' Aussenlager '' ) populated with Polish nationals expelled from Nazi '' Wartheland '' in the process of ethnic cleansing . By October 1943 , most inmates were Polish Jews including nearly 26,000 women . There were similar camps , built locally , at Budzyń , Janowska , Poniatowa , Skarżysko-Kamienna ( HASAG ) , Starachowice , Trawniki and Zasław servicing Nazi German startups which ballooned during this period . War profiteers set up camps in the vicinity of the ghettos via '' Arbeitsamt '' , as in Siedlce , the Mińsk Ghetto ( Krupp ) , and numerous other towns with virtually nothing to eat
