'''Englandspiel''' was the codename given to a highly successful [[Germany|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 [[United Kingdom|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.<ref>Recounted in the book ''A Bridge Too Far'', by Cornelius Ryan.</ref>
