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.

La Chatte

I previously introduced you to some of the brave women who served as foreign agents for the British led Special Operations Executive (SOE).(Click here to read Women Agents of the SOE and click here to read The White Mouse). Today, you’ll meet another female agent of the SOE. Only this time, you’ll see that her exploits don’t quite measure up to the other agents. In fact, you could probably say she was a triple agent and her betrayals shut down the first SOE network in France and cost the lives of many people. The nom de guerre (codename) for SOE agent Mathilde Carré was VICTOIRE. However, she acquired the nickname, La Chatte (The Cat) because some said she walked as quiet as a cat while others said it was her habit of curling up in large armchairs and scratching the arms with her long sharp nails. Mathilde liked her nickname so well that all of her messages to London were signed “La Chatte.”


Did You Know?

We will soon lose the last eyewitnesses to the tragic events of World War II. The soldiers, sailors, men and women who served in the Army Air Corp., Marines, doctors, nurses, and all who supported them will be gone shortly. Survivors of the Nazis’ atrocities, such as Gena Turgel (the “Bride of Belsen” read her story here) and Elie Wiesel, are gone (read about Elie here). The last surviving member of the French Resistance and Companion of the Liberation will soon pass away and be buried with sixteen other combatants, résistants, and deportees in the crypt of the Mémorial de la France combattante at Fort Mont-Valérien in the western suburbs of Paris.

Fortunately, the world has access to written, verbal, and film which document the war and its atrocities. The amount of material available is unprecedented. The Library of Congress began a program called “Veterans History Project” (learn more here)  to provide World War II veterans the opportunity to record their individual stories in writing as well as verbal accounts (hear Violet Gordon’s story here). The number of books written by military participants, former resistance members, and other survivors documenting their first-hand experiences are plentiful. As former classified documents become available, professional historians are able to update and fill-in the history that perhaps wasn’t complete when the first round of books was written between the end of the war and the 1960s. Thousands of images, both still and moving, are available as the U.S. Government provided men and women the opportunity to capture the war in real time.

Today, there are many memorials across Europe honoring the men and women who fought the Nazis and other fascist regimes. One example is the preservation of Fort Mont-Valérien. Today, it stands as a memorial to those who were executed in the hollow depression on its grounds. Another memorial is the privately funded center located on the site of the former Drancy Deportation Center. Elementary school students and others can view and learn the story of Nazi crimes. The director was ten-years-old during the Occupation and he volunteers for the same reason Mont-Valérien’s young director has dedicated his career: to make sure people don’t forget. Then there are the camp survivors such as Gena Turgel who passed away on 7 June 2018 at the age of ninety-five. Most of the survivors dedicated their lives to telling their stories so others would become aware of the horrors and brutality perpetrated by the Nazis. Their primary goal was to ensure people don’t forget. The many Holocaust memorials around the world serve the purpose of reminding us of the Jewish victims who represented approximately ten percent of the war’s total casualties (it is estimated that more than sixty million perished during World War II).

The Holocaust memorials are there to tell us to forgive but never forget. It’s also an opportunity for us to remember the approximately five million others who perished in the death camps alongside the Jews.


Let’s Meet Mathilde Carré

Mathilde Carré (1908−1970) was born in the small town of Le Creusot, a commune (i.e., an administrative division similar to our incorporated municipalities) in the Saône-et-Loire department in the region of Bourgogne—eastern France. Her family was middle class and she was able to attend Sorbonne University, graduating with a teaching degree. In love with a fellow named Marc, Mathilde knew he couldn’t provide the lifestyle she was accustomed to. So, while sitting on the top step of the grand staircase of the Palais de Justice, Mathilde flipped a coin between Marc (“heads”) and another school teacher, Maurice Carré (“tails”). Tails it was and Mathilde and Maurice were married in 1933 but lived apart until they moved to North Africa. By 1939 the marriage had disintegrated and the couple divorced in 1940. The declassified British MI5 file on Mathilde indicates her treatment towards Maurice was indicative of her personality defects which came into play later on during her espionage activities—one of which was operating with unbounded carelessness.

For those of you who have had a cat as a pet (over the years, we’ve had many) know that cats play by their own rules. They are independent and do as they please. A cat is loyal only to themselves and no one else. A cat comes and goes, returning when they want to. Perhaps this should be the real reason why Mathilde Carré was appropriately given the nickname “The Cat.”

Mathilde was in her early 30s and described as attractive but not beautiful. Her face was pale with thin lips and animated green eyes. Mathilde was described as extremely intelligent but very high strung. She always wore a black fur coat, a red hat, and small flat red shoes. Just what every spy should be—conspicuous. Mathilde’s nails were long and sharp, like a cat. Fortunately for her, this cat had many lives. Read More La Chatte
