8. The Nazis Awakened This Dilettante Playboy’s Interest in Politics
After Popov studied in England – where he got expelled from a prestigious prep school – and France, he returned home to study law at the University of Belgrade. When he was twenty two, not long after the Nazis came to power, he headed to Germany to pursue a law doctorate at the University of Freiburg. There, he befriended a rich German student named Johann “Johnny” Jebsen, who had anti-Nazi views. Until then, Popov had simply been a dilettante playboy with no interest in politics. His time in Germany caused him to loathe the Nazis and develop strong political opinions against them.
The young Serb was not discrete about his views, however, and that proved to be a problem in the totalitarian Third Reich. In 1937 he was arrested by the Gestapo, who suspected that he might be a communist, and was tossed into prison. His friend Johnny Jebsen came to his aid and alerted Popov’s father, who in turn got the Yugoslav government involved. After high level contacts between Yugoslavia’s prime minister and Herman Goering, then head of the Gestapo, Popov was released from jail, and expelled from Germany.
Dusko Popov’s experience in Germany did not improve his opinion of the Nazis, and when WWII broke out, he was primed and eager to pay them back if the opportunity presented itself. It presented itself when his friend Jebsen, whose family’s business needed favors from Popov’s, informed him in 1940 that he had joined Germany’s military spy agency, the Abwehr. Popov passed that information to a contact in the British embassy named Clement Hope, along with the observation that Jebsen was not that fond of the Nazis. Jebsen sought to recruit Popov as an Abwehr spy, and when he passed that on the British, they recruited him as an MI6 agent, and urged him to play along with the Germans and join the Abwehr.
Popov was given the codename Ivan by his German handlers, while the British codenamed him Tricycle, because he was in charge of three double agents. Popov eventually turned Jebsen, and recruited his German recruiter into British intelligence as a double agent. Popov also fed information to his native Yugoslavia’s intelligence, which made him a triple agent. He moved to London, and his family’s business activities gave him cover to travel back and forth to neutral Portugal. There, Popov met his Abwehr contacts, and fed them information provided to him by the British service that ranged from harmless truths, to half-truths, to outright lies.
The Abwehr was quite pleased with their spy Dusko Popov. Although some of his German handlers grew suspicious, their suspicions did not make their way up the chain of command. Among other things, an assignment to German military intelligence in Portugal was a cushy gig compared to less attractive ones, such as an assignment to the Eastern Front. Also, many in the Abwehr, from its chief Wilhelm Canaris on down to lower officials such as Johnny Jebsen, disliked the Nazis and did what they could to undermine them.
In 1941, the Abwehr furnished Popov with a small fortune, and sent him to the United States to gather intelligence on American defensive measures. The information sought included an extensive list of questions about the defenses of Pearl Harbor, in which Germany’s Japanese allies were keenly interested. The British worked with the Feds to handle Popov while in the US, but FBI Director J. Edgar Hoover and his G-men lacked the vision and finesse of their British counterparts. Rather than use Popov as a double agent to suss out German intentions and feed them false information, Hoover simply wanted to use him to catch German spies.
J. Edgar Hoover failed to pass on Dusko Popov’s Abwehr questions to American military authorities – particularly the ones that sought information about Pearl Harbor’s defenses. After the Japanese attack wrecked the US fleet there a few months later, Hoover’s oversight should have wrecked his career. However, he buried it so deep that it did not come out until after his death. In the meantime, the prissy FBI Director, whose private life was even more scandalous than the Serb spy, got moralistic about Popov’s promiscuous lifestyle, nightlife escapades, and playboy antics. Hoover even threatened to have Popov arrested under the Mann Act for traveling with a woman across state lines “for immoral purposes”.
The British assigned a naval intelligence officer named Ian Fleming to watch Popov’s every move in the US. The future author of James of Bond followed Popov around as he made the rounds of American night clubs and casinos, womanized, splurged the cash furnished him by the Abwehr, and made a killing on the roulette tables. The style and panache left an impression that found expression years later in Agent 007. Indeed, some famous scenes from Casino Royale were based on Fleming’s observations of Popov in American casinos.
Eventually, Dusko Popov’s relationship with the FBI grew toxic, and as J. Edgar Hoover stewed over the double agent’s antics, things threatened to get worse. So British intelligence recalled their spy to London, where he continued to feed the Abwehr false information. His biggest contribution to the eventual downfall of the Nazis came in the intricate Allied deception plans, collectively known as Operation Bodyguard. Their ultimate aim was to mislead the Germans about the planned invasion of France, scheduled for the summer of 1944.
Operation Bodyguard had three goals. First, conceal the actual date and time of the invasion. Second, convince the Germans after the Allies landed in Normandy that those landings were just diversions intended to juke the Germans out of the Pas de Calais, where the real Allied invasion would land soon thereafter. Third, convince the Germans after the Normandy landings to maintain a strong defense in the Pas de Calais for at least two weeks, rather than send its defenders to reinforce Normandy. Popov played a key role in a sub-plan of Bodyguard, known as Operation Fortitude, which revolved around a fictitious First US Army Group (FUSAG) in southeast England under the command of General George S. Patton.
Dusko Popov passed on to the Abwehr made up details about FUSAG’s units, strength, and organization. His German handlers swallowed his misinformation hook, line, and sinker. Their faith in Popov’s information was reinforced when they eavesdropped on fake radio traffic between fictitious FUSAG formations. To further reinforce the deception, German reconnaissance planes were allowed to fly over and photograph concentrations of FUSAG tanks and transports that were actually inflatable dummies. A spanner was thrown in the works, however, when the Germans arrested Popov’s friend Johnny Jebsen, the Abwehr agent who had “recruited” him to spy for the Nazis.
2. A Double Agent’s Key Contribution to the Allies’ Success in Normandy
When British intelligence learned that Johnny Jebsen had been arrested by the Germans, they feared that he would reveal that Dusko Popov had actually worked for the Allies all along. They thought it was all over for their Agent Tricycle, and suspended his activities and those of his network. Despite torture, however, Jebsen did not let slip that Popov, Agent Ivan to the Germans, was a British spy. When British intelligence realized that the Abwehr still trusted Popov, they put him back to work to continue the deception. He and Operation Fortitude paid off for the Allies in a big way.
After D-Day, the Germans were convinced that the Normandy invasion was not the main event, but only the first in a series of landings. So instead of rush all available reinforcements to contest the Allies in Normandy, they kept powerful formations in the Pas de Calais, to defend it from the “main invasion” by the fictitious FUSAG. Popov’s British handlers had hoped to convince the Germans to keep the Pas de Calais formations in place for two weeks after D-Day. Things worked out better than their wildest hopes: instead of two weeks, the Nazis kept their units there for seven weeks. By the time the Pas de Calais defenders were finally released, it was too late for the Germans.
The Allies took advantage of the breather afforded them by the success of the Operation Bodyguard and Operation Fortitude deceptions to build a powerful beachhead in Normandy. From there, they eventually broke out to liberate France and Western Europe. After Paris was freed from the Nazi yoke, Dusko Popov was sent to the French capital to help establish a British intelligence network. When Yugoslavia turned communist after the war, there was no future for the playboy Popov back in his home country, so he decided to stay put in the West.
Popov was awarded the Order of the British Empire for his wartime exploits – a nice accompaniment to the medals given him by the Germans during the conflict – and eventually became a British citizen. He prospered as a businessman, and had no intention to reveal his wartime activities. In 1972, however, John Masterman published The Double Cross System in the War of 1939 to 1945, a deep dive in British wartime intelligence. That convinced Popov to write up his own account, and in 1974 his autobiography, titled Spy Counter-Spy, was published. A playboy to the end, he died in 1981, after years of heavy smoking and drinking, and many, many, women.
