A former Sheppey woman who was a teenage spy in Nazi-occupied France during the Second World War has died.

Sonia d’Artois, nee Butt, who was born in Eastchurch, was parachuted in near Le Mans nine days before D-Day, aged just 19.

The 90-year-old’s exploits came to light in The Women Who Spied for Britain by Canadian author Robyn Walker.

It tells how Mrs d’Artois set about recruiting, arming and training French Resistance members.

She had joined the Women’s Auxiliary Air Force at 18 where – having spent most of her childhood in France – her second language skills brought her to the attention of the Special Operations Executive, the British espionage organisation.

While training, she met and married Canadian spy Guy d’Artois.

Her landing in France did not go to plan as a container carrying her wardrobe was picked up by an enemy patrol, alerting them to the fact there was a female spy in their midst.

Despite this setback, Mrs d’Artois, who was known as Agent Blanche, began work immediately.

Her expertise with explosives was in high demand among the Resistance fighters and she became known for her fearlessness, taking part in night-time ambushes against German convoys.

Mrs d’Artois used her looks to establish friendly relations with the occupying forces, in particular one German colonel.

However, her cover was nearly blown one evening when, as the two were chatting in a cafe, her handbag slipped off her chair and the revolver inside made a loud metallic clunk on the floor. She sensed the colonel knew what it was so, thinking fast, she pulled out a forged firearms permit signed by the Gestapo.

Her pretence of being friendly to German troops almost landed her in trouble again after the liberation when a group of French troops grabbed her and accused her of being a collaborator.

Luckily the incident was spotted by her friends in the Resistance who explained who she was and she was freed.

Mrs d’ Artois was reunited with her husband in September 1944, and they moved to Quebec in 1946, where they raised six children.

The grandmother suffered from Alzheimer’s in later life and was cared for by her family.

Mrs d’Artois was later made an MBE in recognition for her services and was mentioned in dispatches. She passed away on December 21.
