Operation Vermin (Aktion Ungeziefer) and Operation Consolidation (Betriebskonsolidierung, its Stasi codename), also called Operation Cornflower (Aktion Kornblume) were two large-scale operations by the government of East Germany (the German Democratic Republic, GDR) meant to remove "politically unreliable" people from the exclusion zone along the Inner German border.[1] The first operation was executed in June 1952 as “Operation Vermin”, the second one in October 1961 as “Operation Consolidation” and “Operation Cornflower”.
