Île d'Yeu
Having served in French Canada and Governor of the Île d'Yeu from 1768, Verteuil was in command at La Rochelle at the opening of the French Revolution. He then became a commanding lieutenant-general of the Catholic royalist army during the revolt in the Vendée. Captured at Savenay, he was executed as a prisoner of the National Convention for his counter-revolutionary activities (condemned as a "brigand") in the Vendée.
