Reichsgau Wartheland
According to post-war testimony of Wilhelm Koppe, Higher SS and Police Leader for "Reichsgau Wartheland", Koppe received an order from Himmler to liaise with Greiser regarding the "Sonderbehandlung" requested by the latter. Koppe entrusted the extermination operation to "SS-Standartenführer" Ernst Damzog from Security Police in Poznań. Damzog supervised the camp's daily operations thereafter.
