Early Life and Background
Jacques Vaillant de Guélis was a distinguished World War Two hero recognized by both Wales and France. His death, involving a German soldier just days after the war ended, remains enveloped in mystery more than 80 years later.
Born in Cardiff in 1907 to French coal magnate parents, Jacques was fluent in English, French, and Breton. At the outbreak of the war, this Oxford graduate abandoned a successful advertising career to enlist in the Army.
Military Career and SOE Recruitment
Jacques was soon recruited into the Special Operations Executive (SOE), a top-secret organization. He undertook multiple missions behind German lines, organizing and equipping French resistance fighters.
Just eight days after Victory in Europe (VE) Day on May 8, 1945, during his final mission to gather intelligence on concentration camps, he was fatally injured near Flossenburg Camp, close to the current Czech Republic border. He was struck by a car driven by a German soldier who had recently been working at the camp.
The exact circumstances of the incident remain unclear. Author Greg Lewis noted,
"the case was closed almost as soon as it was opened".
Family and Early Years
Jacques was born on what is now Museum Place near Cardiff city center. His family home is marked with a Blue Plaque honoring his bravery.
Greg Lewis, a Cardiff author specializing in espionage, resistance, and World War Two history, became interested in Jacques while researching Cathays Cemetery, where Jacques’ ashes lie in a family plot.
Background and Suitability for SOE
Greg explained Jacques’ background was typical of the profile sought by the SOE.
"Jacques' family moved to Cardiff in order to export coal to Brittany. He would have been educated, sophisticated and, most importantly, very difficult for the Germans to tell apart from a native-born Frenchman.
What's more, from his earliest days in France on the outbreak of war, he'd proved himself to be incredibly resourceful in extreme circumstances."
Early War Service
Jacques was initially posted as a liaison officer to the British Expeditionary Force during the early days of the war in 1939. After the German invasion of France, he was evacuated from Dunkirk.
Shortly after returning to Britain, he was sent back to France on June 12, 1940, via Cherbourg to assist trapped soldiers in escaping.
Greg described,
"After he'd coordinated all the evacuations which were possible, he had left it too late to leave via the Channel himself, so headed south via Marseille and over the Pyrenees into supposedly neutral Spain.
There he was interned before the British government secured his release on a ship back to Glasgow."
SOE Recruitment and Missions
This daring escape brought Jacques to the attention of the SOE in April 1941. He was recruited by Major Lewis Gielgud, brother of actor Sir John Gielgud, and was reportedly interviewed for the role by Prime Minister Winston Churchill himself.
In August 1941, Jacques parachuted into Vichy France to support the French resistance by providing forged travel documents, radio equipment, and military intelligence.
After completing his mission, he signaled for extraction and was picked up by the RAF from a makeshift airstrip weeks later.
Promoted to major, Jacques then joined General Charles De Gaulle's Free French Army in Algeria, advancing against German forces through North Africa and into Corsica.
He engaged in hand-to-hand combat until the Germans were expelled from Corsica in 1943, after which he returned to Britain for briefing on another secret mission shortly after D-Day.
Resistance Coordination and Final Mission
Greg stated,
"In July 1944 Jacques was again dropped behind enemy lines to coordinate resistance fighters who were hampering the Germans as they attempted to retreat deeper away from the front.
It would have been highly unusual for somebody of his importance to be so directly involved, because of the risk of his capture and the knowledge he could have potentially disclosed, but such were his skills in the field that it was considered vital to have him on the ground."
For his final and fatal operation, Jacques was deployed inside Germany to investigate the fate of fellow SOE officers captured and sent to Flossenburg concentration camp in Bavaria.
On May 16, 1945, just days after the war ended, he was outside the camp gates when a car driven by a German soldier who had recently worked there struck him.
Suspicion and Investigation
Since the incident, suspicions have arisen that Jacques may have been deliberately targeted due to information he uncovered at Flossenburg.
Greg expressed,
"Those early days were crucial in the gathering of evidence towards what would later become the Nuremberg Trials. There would have been many Nazis who really wouldn't have wanted that information to become public.
Germany was so chaotic then, that it's highly unlikely to have been an organised hit, but could it have been one Nazi acting on his own?
Maybe not, as the records don't make very much of it, and the case was closed almost as soon as it was opened."
Aftermath and Honors
Following the crash, Jacques was flown to Paris for emergency treatment and later transferred to Burtonwood Hospital in Staffordshire, where he underwent further operations but ultimately died on August 7, 1945.
He was posthumously awarded the Member of the Order of the British Empire (MBE) by Britain and the Croix-de-Guerre with Palm by France, the highest French award for gallantry.
Legacy
Greg lamented that Jacques’ personal experiences were never recorded in his own words.
"I've written about several SOE operatives who survived the War, and their recollections are as insightful as their military record.
Though with Jacques, all we have is his glittering personnel file, but sadly personnel isn't the same as personal."
