Note 19 — XXXV

Pierre Charles le Sueur went to Canada when a young man, and engaged in the fur-trade. In 1693, while commandant at Chequamegon, he erected two forts—one on Madelaine Island, in Chequamegon Bay (Lake Superior), and another on an island in the Mississippi, near Red Wing, Minnesota. Later he discovered lead mines along the upper Mississippi. In 1699 he returned from a visit to France, and under Iberville's directions searched for copper mines in the Sioux country, where Le Sueur had earlier found green earth. Le Sueur reached the mouth of Missouri River (July 13, 1700) with nineteen men, according to Bénard de la Harpe's manuscript, compiled from Le Sueur's Journal—with twenty-nine men, as related by Pénicaut, a member of the expedition. The company was later increased to perhaps thirty or forty, but not ninety, as Flagg says. Le Sueur ascended the Mississippi, and its tributary the Minnesota, and erected a fort in August, 1700, one league above the point where the Blue Earth River (St. Peter's River, until 1852) empties into the Minnesota. This fort he named l'Huillier, in honor of his patron in France. Flagg has confused this site with that of Fort Armstrong at Rock Island, Illinois. In May, 1701, Le Sueur left the fort in care of d'Eraque, who remained in charge until 1703, when he abandoned the place.
