Abwehr Lieutenant Colonel Hermann Joseph Giskes (28 September 1896 – 28 August 1977) was a wartime intelligence operative primarily stationed in the occupied Netherlands, and head of Abwehr Section IIIF. He is best known as one of the leading lights behind the Englandspiel operation. Giskes' activities were responsible for supplying a great deal of disinformation to British intelligence services for much of World War II, and for the arrest of more than 50 Allied agents. Giskes first succeeded in gaining the partial cooperation of captured British agent Hubertus Lauwers, who sent encrypted messages (but missing security checks) back to British SOE at Giskes' direction, under duress. Then dozens of agents parachuted in succession, and were captured by the Germans, along with tons of equipment.
