French fort on right bank of St. Lawrence, site of present town of Ogdensburg. Established about 1718. The fort was rebuilt or strengthened in 1748. Bougainville in 1757 described it as "a poor fort of wood palisades with a small garrison". A mission for Indians of Five Nations was established there by Abbé Piquet of the Sulpicians. About 100 Indians of the Five Nations assembled there for trade. It was a King's post and one of the very few from which no "eau-de-vie" was given out to the Indians. The mission had been only recently established in 1757. The fort was also known as "La Galette" and location shown on map of French claims 1756 (No. 10) also No. 97.
