SAINT PIERRE, Legardeur Jacques de (san-pc-air), French soldier, born in Normandy in 1698; died near Lake George, Canada, in 1755. He went in early youth to Canada as ensign in a regilnent of marines, served against the Iroquois, and took a commendable part in the war of 1740 against the English. In 1752 he was sent on a journey of discovery toward the Rocky mountains, which he was among the first to explore, and, on his return in October, was ordered by Governor Duquesne to Ohio, where the French had first built Fort de Bceuf upon French creek, which commanded the route to Alleghany river. On 11 December he received there George Washington, then adjutant-general of Virginia, who brought a letter from Governor Dinwiddie inviting the French to withdraw from English territory. According to the journal of Washington, printed at Williamsburg just after his return, he was extremely well received by Saint Pierre, whom he depicts as an able and courteous commander. In the spring of 1753 Saint Pierre was superseded by Contreeceur and appointed commander of the Indian auxiliaries, and in that capacity he rendered great services in Baron Dies-kau's expedition. He was subsequently killed in the action where Whiting's regiment was routed. Saint Pierre's account of his journey to the Rocky mountains is preserved in the National library of Paris, and has been published in the collection of John Gilmary Shea (New York, 1862). It is entitled "Memoire ou journal sommaire de Jacques Legardeur de Saint Pierre."
