Agent Jack, “M” and the Fifth Column

What is the “Fifth Column”? It is a term that originated during the Spanish Civil War (1936-1939) to describe a group of people who undermine ⏤ from within ⏤ another larger group. Fifth Column activities can be visible to all or covert and clandestine in nature and typically result in sabotage, disinformation, and espionage. In Britain, its Fifth Column problem, in the form of the British Union of Fascists, was well-known to Churchill and others. However, below the surface, ordinary British citizens were willing to sell out their country to Hitler and the Nazis. They shared a common admiration for Hitler and his anti-Semitic philosophy and thought Britain would be better off under German rule.

It wouldn’t be until an unassuming low-level London bank clerk took a leave of absence and resurfaced as a Gestapo agent that the intelligence agencies became fully aware of the magnitude of the underground Fifth Column trying to pass secret military intelligence to the Nazis.


Did You Know?

Did you know that John F. Kennedy was not the only United States president to have been saved at sea during World War II? After turning eighteen, George H.W. Bush enlisted in U.S. Navy and served as a pilot of a Grumman Avenger Torpedo aircraft. Two years later, Lt. Bush flew one of his fifty-eight missions alongside three other Avenger bombers. Each plane carried three aviators. Their mission was to bomb the radio station located on the small island of Chichijima.

Despite the intense flak and anti-aircraft fire, Lt. Bush and the other planes managed to take out the radio station. His plane was hit and falling at a speed of one hundred ninety miles per hour when Lt. Bush bailed out hitting his head on the plane’s tail. He ended up in the water and was able to inflate a small raft which he floated in for four hours before the USS Finback, a submarine, picked him up. This was the second time Lt. Bush had to be plucked out of the water during a mission.

Unfortunately, the two airmen flying in his plane did not survive. The other planes went down and seven airmen were captured by the Japanese. They were tortured, beheaded, and their livers were cut out for their captors to eat.

Lt. George H.W. Bush was the only survivor of the mission. He would be awarded the Navy’s Distinguished Flying Cross for this mission in addition to three Air Medals, and the Presidential Unit Citation for his service during World War II.

British Military Intelligence

There are two primary intelligence departments in Britain: Security Service or MI5 (Military Intelligence Section 5) and Secret Intelligence Service (SIS) or MI6. While MI6 is responsible for foreign intelligence, it is MI5 that provides domestic counterintelligence. It is similar to the American intelligence structure of the CIA (foreign) and FBI (domestic).

MI5 was founded in 1909 and is under the authority of the Home Secretary within the cabinet of the prime minister. It had its troubles during the inter-war period (between the two world wars) due to weak leadership. However, its greatest accomplishments during World War II were Operation Double-Cross (click here to read the blog The Double Cross System) and Operation Fifth Column. Both of these initiatives were headed by MI5 spymaster Maxwell Knight.

Maxwell Knight (1900-1968) is generally considered to have been Ian Fleming’s model for the character of “M” in the James Bond series. In the mid-1920s, Knight was working undercover for MI5 by infiltrating early British fascist groups as well as communist cells in England. Knight became MI5’s director of intelligence and eventually head of Section B5(b) which was responsible for infiltrating agents into subversive organizations.

The Double Cross System

Undoubtedly, many of you have heard the story of the fake army which was used to deceive Hitler and his generals into planning for a cross channel invasion (across the Strait of Dover to Pas de Calais). It is true but the story is somewhat more complex and as wartime documents seven decades old are declassified, historians are only now able to fill in missing gaps and answer why Hitler reacted the way he did to the Normandy invasion.


Did You Know?

Did you know that the author of the James Bond series, Ian Fleming (1908−1964), worked for British Naval Intelligence during World War II? He was promoted to commander and initially served as the assistant to the Director of Naval Intelligence, the curmudgeon Rear Admiral John Godfrey (1888−1970). In that role, Fleming represented Godfrey in many high-level meetings with the British Secret Intelligence Service, Special Operations Executive (SOE), and the Prime Minister’s staff among other wartime government organizations including the United States Office of Strategic Services (OSS—the predecessor to the CIA).

You will shortly meet Duško Popov, one of the principal double agents for the Double Cross System. He was a Serbian intelligence agent who was flamboyant, wealthy, promiscuous, and well-connected in France and the United States. Popov offered his services to the German Abwehr (military intelligence) with the intent all along of becoming a double agent. Popov was anti-Nazi and promptly became a double agent working for MI5 (British Military Intelligence, Section 5). Stationed in Lisbon in mid-1941, Popov was paid $80,000 for his MI5 services. At the time, Fleming had been assigned to shadow him. Popov frequented a local casino where one evening he became upset with the way the house was breaking the rules to benefit one of its affluent baccarat clients. Popov placed a $50,000 bet which the other gentleman was obliged to match, much to his chagrin. This ended with Popov collecting his money and an admonishment to the dealer, “I trust you’ll call this to the attention of the management and that in the future such irresponsible play will be prohibited. It is a disgrace and an annoyance to the serious players.” As he walked away, Popov winked at Fleming whom he knew was with British Intelligence and had been watching him.

Many of the Bond books and its characters were based loosely on Fleming’s wartime experiences. Bond’s boss, M, was based on Godfrey while Miss Moneypenny was loosely based on Vera Atkins, one of leaders of the SOE (click here to read Women Agents of the SOE). It is thought the James Bond character is likely based on Duško Popov and the reason we see Bond in so many casinos stems from Fleming’s experience that evening in the Lisbon casino.

One last tidbit of information: Popov once told Fleming that his uncle, Milivoj Popov, lived in Belgrade, Serbia and the number he called to speak with his uncle was 26-007.


Deception strategies were used by the Allies and Germans against one another throughout World War II. However, by 1942, the Americans and British held the upper hand: intelligence was gained through the top secret Ultra program by decrypting German messages using the Nazi military Enigma machine at Bletchley Park. Deception methods created primarily by British intelligence were becoming increasingly complex and successful. As Churchill, Roosevelt, and Stalin agreed in late 1943 on plans for an invasion of Europe, the Allies came up with the largest deception plan to date to be used against the Nazis.

Operation Bodyguard and Fortitude

Operation Bodyguard was the American and British-led umbrella deception plan to mislead the Germans into thinking the inevitable invasion of Europe would take place at a location other than the real invasion site. Additionally, the plan was to deceive Hitler about the actual date, time, and size of the assault force. It was formulated in 1943 once the Allies agreed to a 1944 invasion date.
