"Englandspiel Monument" or The Fall of Icarus (by Titus Leeser [nl]) in The Hague memorializes the 54 agents who were dropped into the Netherlands during Das Englandspiel. The inscription says, in part "They jumped to their death for our freedom."

Operation North Pole (German: Unternehmen Nordpol), often referred to as the Englandspiel ("England Game"), was a counter intelligence operation of the Abwehr (German military intelligence) during World War II. German forces captured Allied resistance agents operating in the Netherlands and used the agents' codes to dupe the Allies into continuing to provide the agents with information and supplies. About 50 Allied agents were identified, captured and executed.



The British Special Operations Executive (SOE) sent Dutch intelligence agents into the occupied Netherlands. The operatives were usually flown out at night and dropped by parachute from converted Handley Page Halifax bombers or landed in fields by Westland Lysander STOL aircraft, which could also pick-up agents at the same time to fly back to Britain. SOE air operations were based at RAF Tempsford. As early as 1942, the operation in the Netherlands was penetrated by the German counter-espionage under Major Hermann Giskes of the Abwehr and continued under German control.

Apprehended radio operators continued broadcasting encrypted messages but without security checks, which should have alerted SOE that they had been compromised. SOE's head of codes Leo Marks claims to have quickly realised that, unlike all other coded messages, the Dutch messages contained no errors which made them indecipherable. He reasoned that this was because they were not coded in the field but by German cryptographers. In the documentary Churchill's Secret Army he recounts how a wireless operator ended a telegraphic radio communication with "HH", which stood for Heil Hitler and was the usual closing for German communications. The other party instantly replied "HH" which indicated it was a German who was used to doing it automatically and not a British agent who would have been confused by the two letters. Finally, he sent them a deliberate indecipherable message of his own, which was replied to. He reasoned that no ordinary agent could have reconstructed his message. He reported these findings to his superior who told him to not discuss the matter with anybody else; no action was taken.

It was reported that agents who were supposed to return from the Netherlands had met with various calamities and so could not return. In 1943, two Dutch agents escaped but their claims on returning to Britain were dismissed (and they were arrested for suspected counter-espionage) due to a fake message sent by Giskes that two German agents were being sent to the UK from the Netherlands.[1]

The operation was not shut down until Giskes sent a cynical clear text message to SOE on 1 April 1944 complaining about the lack of recent business given that he had been servicing them for so long. Giskes' message also "promised a warm welcome to any further agents SOE wished to insert into the Netherlands".[2]

By November 1942 it was clear to the signals section that agents were in German hands. The fact that neither the Dutch section, overseeing operations in the Netherlands, nor other services were notified is probably motivated by inter-departmental rivalry between SOE and the rival Secret Intelligence Service ("C") from which SOE had been created.[3]

It has also been argued that SOE had set up the operation to lead the Germans into believing that an invasion would take place in the Netherlands (rather than Normandy). Similar allegations have been made about the fate of Francis Suttill and the SOE "aa" network in France but the decision to land at Normandy had not been made until late into the Englandspiel saga.

Marks claims in his book that the real issue was internal rivalry between the SOE and the SIS; the former did not want to admit error. Marks says he was ordered to withhold important cryptographic information from people investigating the Dutch operation at the time.

After the war, SOE was reproached for serious flaws in the preparation of the missions and for ignoring warnings that agents had been caught, notably the absence of security checks, which were deliberate errors introduced into messages by the sending agent, the scheme for which was known only to the agent and SOE. The existence of security checks in messages indicated that the sender was the legitimate agent and that they were acting under free will. The absence of security checks represented a vitally important duress code, which should have warned SOE that the sender was either an imposter or a legitimate agent who had been captured and coerced into working for the Nazis. Repeatedly ignoring the significance of the absent security checks was a serious violation of the SOE's own transmission protocol.

In popular cultureEdit

  • Englandspiel is the subject of the "Dead on Arrival" episode of the Secret War documentary series,[4] and of the "Confusion Was Their Business" episode of the Secrets of WWII documentary series,[5] which both aired on the Military Channel in the United States.
  • Englandspiel is the historical inspiration for "Elise," an episode in Season 8 of the historical television drama Foyle's War.
  • The Englandspiel is also featured in the Dutch World War II adventure bookseries Engelandvaarders by the Dutch author Klaas Norel [nl]

Englandspiel is also the basis for the 1956 Italian film 'London chiama Polo Nordo/The House of Intrigue', directed by Duilio Coletti with Curt Jurgens.
