In the late summer of 1944, German records listed 7.6 million foreign civilian workers and prisoners of war in the German territory, most of whom had been brought there by coercion.[1] By 1944, slave labour made up one quarter of Germany's entire work force, and the majority of German factories had a contingent of prisoners.[13][25] The Nazis also had plans for the deportation and enslavement of 50% of Britain's adult male population in the event of a successful invasion.[26]
