Albert Forster ranked at a Lieutenant General and a member of the National Socialist German Workers Party but never carried out Hitler's genocide.
Forster was directly responsible for the extermination of non-Germans and was a strong supporter of Polish genocide, which he had advocated for before the war. 
Under his administration as the Gauleiter of Danzig-West Prussia (the other German-annexed section of occupied Poland aside from the Warthegau) during the Second World War, the local non-German population of Poles and Jews was classified as sub-human and subjected to extermination campaign involving ethnic cleansing, mass murder, and in case of some Poles with German ancestry, forceful Germanisation.
