Englandspiel
Englandspiel ('England Game'), or Operation North Pole (German: Unternehmen Nordpol), was a successful counterintelligence operation of the Abwehr (German military intelligence) from 1942 to 1944 during World War II. German counter-intelligence operatives, headed by Hermann Giskes of the Abwehr and Joseph Schreider of the Sicherheitsdienst (SD), captured Allied resistance agents operating in the Netherlands and used the agents' radios and codes to dupe the United Kingdom's clandestine organization, the Special Operations Executive (SOE), into continuing to infiltrate agents, weapons, and supplies into the Netherlands. The Germans captured nearly all the agents and weapons sent by the United Kingdom (Britain).
