DeValle was born in Auvergne, southern France, to two brick-makers. He was drafted into the French Army in 1918, fighting in the Second Battle of the Marne. DeValle was promoted to Staff Sergeant by the time the war ended, and he was made a Lieutenant-Colonel by 1939. That year, he was transferred to the colonies of France, sent to defend Newfoundland against a possible German invasion. He constructed Fort Lavalle, named after Pierre Lavalle, one of the French government members, and was in charge of 500 Vichy troops in the fort. DeValle was captured near Aisne-del-Norte by Canadian troops led by Sergeant James Blackburn Hawthorne, and was led to the commander of the British troops, Brigadier Nathaniel Smithford, to whom he surrendered. He was barged out of Newfoundland with 1,000 other captives, held in England as a prisoner of war. DeValle was held in Nottinghamshire's impromptu POW camp, and returned to France in April 1946, living in Paris until he died.
