He was active in the establishment of French power in the Ohio Country, and was the commander of Fort Duquesne (at the site of modern Pittsburgh, Pennsylvania) in 1755 when it was threatened by Edward Braddock. Born into a family with large landholdings in the Saint Lawrence River valley, he stayed in North America after the French and Indian War and its fall of New France to the British. He was called "the third most influential Canadian" by the British governor of the Province of Quebec, Guy Carleton.
