Hermann Giskes, Abwehr, Netherlands
Englandspiel (England Game), or Operation North Pole (German: Unternehmen Nordpol), was a successful counter intelligence operation of the Abwehr (German military intelligence) from 1942 to 1944 during World War II. German forces captured Allied resistance agents operating in the Netherlands and used the agents' 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).
Englandspiel was a "catastrophe" for SOE and the Dutch resistance, "a textbook illustration, the world over, in how not to conduct clandestine work." Fifty-four SOE agents sent from England were captured by the Germans and 50 were executed. The Dutch resistance was substantial in numbers but lacked weapons. If armed, as had been the objective of SOE, it might have played an important role helping the allied military forces in their failed attempt to expel the Germans from the Netherlands in 1944. 
The Special Operations Executive (SOE) was created by the United Kingdom on July 22, 1940 in accordance with Prime Minister Winston Churchill's directive to "set Europe ablaze." The objective of SOE was to undertake "irregular warfare" with sabotage and subversion in countries occupied by Nazi Germany and other Axis powers. SOE agents in occupied countries allied themselves with resistance groups and supplied them with weapons and equipment parachuted in from England. Section N was created within SOE to deal with the Netherlands. Section N had four chiefs during the war: R. V. Laming, Charles Blizard (known as Blunt), Seymour Bingham, and R. I. Dobson. In the words of M.R.D. Foot, official historian of the SOE, Section N was "not always noted for efficiency." 
The opposite numbers of the SOE leaders in German-occupied Netherlands were Majors Hermann Giskes of the Abwehr and Joseph Schreider of the Sicherheitsdienst (SD), the intelligent service of the SS.
The Netherlands presented geographical challenges to the Dutch resistance and the British intelligence agencies wishing to infiltrate agents and supply arms and supplies to the resistance groups. The country was densely populated and lacked forests and mountains where resistance forces could hide; isolated areas suitable for landing fields of airplanes or parachute drops of arms and supplies for the resistance were hard to find; the coast was flat and the beaches were guarded and often mined by the Germans offering little opportunity to bring in agents and supplies by boat or submarine. Moreover, the Netherlands did not border any neutral, unoccupied country which could be used a staging ground for resistance activities. 
A bad beginning
Lynne Olson, author The Last Hope.
In late summer 1941 a Dutch agent of the British intelligence agency MI6 was arrested by the Germans in the Netherlands. He had with him a large number of coded messages and a German cryptographer, Sergeant E. G. May, was able to learn the MI6 cipher system. In February 1942, two MI6 agents were captured in the Netherlands which added to the German knowledge of the British codes. At this time SOE depended upon MI6 for its communications and ciphers.
Meanwhile, SOE was training Dutch agents to infiltrate into the Netherlands to help a fledgling resistance movement. The agents complained about the deficiencies of their training program. They were given clothing, easily identifiable as British, to be worn in the Netherlands, security was lax, and SOE could not provide the agents in training with names and addresses of contacts and safe houses which they would need in the Netherlands. In response, the British confined the disaffected trainees and only released them in December 1941 after a complaint by the Dutch government-in-exile in England and after the agents signed a agreement to remain silent about their complaints.
SOE's first two Dutch agents, wireless operator Huub Lauwers and saboteur Thys Taconis, parachuted into the Netherlands on the night of 6/7 November 1941. Lauwers was captured on 6 March 1942. He was persuaded to send messages to SOE in London, but he omitted from the messages the two security checks (deliberate errors) that were required to be introduced into messages by the sending agent, the scheme for which was known only to the agent and SOE. The presence 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 impostor 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. However, SOE London ignored the absence of the security checks and accepted the messages as genuine. Lauers continued to transmit messages without the security checks and even inserted the letters CAU and GHT ("Caught") at the beginning and end of messages. SOE London paid no mind.
The messages Lauwers transmitted while a prisoner of the Germans included requests that additional agents and supplies be sent to the Netherlands. SOE responded positively. Agents and supplies, including weapons, were usually flown out of Britain at night and dropped by parachute from converted Handley Page Halifax bombers or landed in fields by Westland Lysander STOL aircraft. SOE air operations were based at RAF Tempsford. The agents and supplies were met on arrival and captured by the Germans.
Several captured Dutch 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 also claims to have realised that, unlike all other coded messages from agents in other countries, the Dutch messages contained no errors. He reasoned that this was because they were not coded in the field by harried and harassed wireless operators, but by expert German cryptographers. The Dutch messages were too good to be genuine. In the documentary Churchill's Secret Army Marks 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 that the transmitter was a German who was used to adding "HH" to messages automatically and not a British agent who would have been confused by the two letters. Finally, Marks sent a Dutch agent in the Netherlands a deliberately garbled message. Marks reasoned that no ordinary SOE agent could decrypt the message, but that the German cryptographers could and would. The Dutch agent responded to the garbled message, which indicated to Marks that he was transmitting under the control of the Germans. Marks reported these findings to his superior who told him to not discuss the matter with anybody else; no action was taken. Marks claims that the real issue was internal rivalry between the SOE and the SIS; the former did not want to admit error.
German wireless operators reported mock resistance groups and sabotage successes to SOE London. When SOE London requested that a agent return to England, he would suddenly meet with a calamity of some sort so could not return. In January 1943, Marks wrote a report to SOE leaders about his suspicions that all or nearly all SOE agents in the Netherlands were in German hands, but it was months before any action was taken. Neither the Dutch section, overseeing operations in the Netherlands, nor other services were notified of his suspicions. The failure of SOE leadership to respond to signs that the Dutch program was controlled by the Germans was probably motivated by both denial of warning signs and inter-departmental competition between SOE and the rival Secret Intelligence Service ("C") from which SOE had been created.
End of Englandspiel
Hemann Giskes, Abwehr, Netherlands wireless message to SOE headquarters, 1 April 1944
In the fall of 1943, two Dutch SOE agents, Pieter Dourlein and John Ubbink, escaped from Haaren concentration camp, made their way to Switzerland. and reported Englandspiel to the Dutch Legation there which passed the information along to the British government. The two agents then utilized one of the escape and evasion lines to get to Spain and hence to London. The Abwehr's Giskes, however, anticipated their arrival by sending a fake message, ostensibly from another SOE agent, that Dourlein and Ubbink were turncoats, having become German agents. The two were imprisoned on their arrival in London and remained in a British prison until after the Normandy Invasion in June 1944. They were later honored by the government of the Netherlands.
Englandspiel was already on its last legs in fall 1943. The Royal Air Force (RAF) which supplied the planes and pilots for SOE had suspended SOE flights to the Netherlands after May 1943 because of the high casualties to aircraft and airmen. The RAF had noticed that its flights to the Netherlands always arrived without opposition and that landing areas were "too bloody perfect," but planes were fired upon during their return trip to England, suffering unusually high losses. In less than a year 12 RAF aircraft were shot down during their return flight from SOE missions in the Netherlands.
The denouement of Englandspiel came on 1 April 1944 when Giskes sent a taunting message to SOE complaining about the lack of recent business from England 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.
The fifty Dutch SOE agents that had been captured by the Germans were transported to Mauthausen concentration camp in September 1944 as allied military forces were advancing into the Netherlands and were executed. Giskes, the Abwehr mastermind of Englandspiel, was arrested by the British, but after the war was employed by the United States during the occupation of Germany.
Some of the officials of the Dutch government-in-exile in London refused to cooperate with SOE when the details of Englandspiel became known to them. They were ordered to do so by the Dutch Prince Bernhard, and a fresh start was made in mid-to-late 1944 under new leadership at SOE. Twenty-five well equipped and trained sabotage teams of two Dutch agents each were parachuted into the Netherlands. However, engendered by Englandspiel the British distrusted the Dutch resistance which prevented it from having an impact in Operation Market Garden, the unsuccessful offensive by allied military forces in the Netherlands in September 1944. The spearhead of the British forces, the First British Airborne Division, was ordered not to cooperate with the resistance. Had it not been ignored, the resistance would have been helpful in providing badly needed intelligence and communications to the division which had to be withdrawn from the battlefield after heavy losses.
Conspiracy theories in the Netherlands alleged that a traitor in SOE caused the Englandspiel and that Dutch agents were sacrificed to conceal allied plans for an invasion of the Netherlands. "For many, it was simply impossible to fathom how the devastation caused by das Englandspiel could have been the result of stupidity and ineptness." The contrary and more accepted view of M.R.D Foot is that “the agents were victims of sound police work on the German side, assisted by Anglo-Dutch incompetence in London."

In popular culture
- Englandspiel is the subject of the "Dead on Arrival" episode of the Secret War documentary series, and of the "Confusion Was Their Business" episode of the Secrets of WWII documentary series, 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 Vliegers in het Vuur by the Dutch author Klaas Norel
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, and based upon the novel by Giskes.
