Englandspiel

Englandspiel was the codename given to a highly successful German counter-espionage operation in the Netherlands during World War II. The occupying German fores obtained the codes used by the Dutch reistance in radio contact with Britain, and by impersonating the resistance the Germans were able to capture 57 agents sent in from England, and arrest hundreds of Dutch resistance personnel. The pinnacle of Englandspiel was the failure of Operation Market Garden, an Allied attempt to break through German lines at Arnhem in September of 1944.
