Among other deeds committed by Krüger were : responsibility for eliminating rebellions in the extermination camps , setting up forced labour camps , the employment of police and SS in the deportations of Jews from ghettos in General Government to extermination camps , and the driving out ( ethnic cleansing ) of over 116,000 Polish farmers ( 30 thousands of them were children ) from the area around Zamość , known as Aktion Zamosc . Most of the children were sent to concentrations camps , labour camps and blonde and enough young to the III Reich for Germanisation , or to do a slave work on German farms . Only 800 Children of Zamość were successfully reclaimed after the war . Disagreements with governor general Hans Frank led to Krüger 's dismissal on 9 November 1943 . He was replaced by Wilhelm Koppe . Due to Krüger , Koppe and their soldiers and policemen , altogether more than 6 million Poles ( 2.9 million of them were Polish Jews ) were killed in gas chambers , in forced labour camps , during mass shootings , from hunger , disease , cold or because of mandatory expulsions from their houses or farms , and transportation of these empty-handed victims on the bare fields of General Government . Almost the entire population of Polish Jews was exterminated . Travelling Roma were treated by German authority equally to Jews ( Romani genocide ) . The economical downfall of the Polish industry , the railway network , the agriculture , the forestry and total destruction of the country ( the retreating Germans blew up Polish sea port in Gdynia ) were not in connection with the military actions only . Most of the victims have perished due to political doctrine , classifying all the Slavic nations as subhumans , and other administrative and compulsory orders and restrictions set up by the new government , with SS-Obergruppenführer Krüger as the most senior commander of SS and Police in German-occupied Poland
