She became best known for her actions fighting against the Spanish Empire during an incursion near Biriatou in July 1793.
She married François Leyrac on 5 March 1792, and signed up alongside her new husband and her brother Cyprien Barreau for the 2nd Battalion of the Tarn in the Army of the French First Republic.
Under the command of Théophile Corret de la Tour d'Auvergne, they were engaged by the Spanish forces.
The National Convention granted her 300 livre tournois in recognition of her service, and the following years she remained in the train following the army as her husband continued to serve.
The 1793 Annales du Civisme et de la Vertu characterized her as a national hero.
