Not to be confused with Fort St. Louis (Shelburne County, Nova Scotia)
Fort St. Louis (also known as Fort St. Francois a Canso, Fort Chedabuctou, Fort St. Louis a Chedabuctou) was a French fort built in Chedabucto, Acadia (present day Guysborough, Nova Scotia). The British attacked in 1720 as they built Fort William Augustus at Canso.
The village of Guysborough was first settled by Europeans in 1634 by Isaac de Razilly. He built a fort named Fort St François à Canso at the entrance to the harbour. In 1655 Nicolas Denys, governor of the new St Lawrence Bay Province, built Fort Chedabuctou on Fort Point to serve as his capital. The fort was later replaced and renamed Fort St Louis.
In 1682, a permanent settlement was started by Clerbaud Bergier. A group cleared land and spent the winter with the first crops being planted in 1683. Louis-Alexandre des Friches de Meneval landed at Chedabouctou in 1687 when arriving to take up his position as governor of Acadia.
Claude Bergier led other merchants from La Rochelle, France in enjoying a fishing monopoly in Acadia. In 1682, Fort St. Louis was established by the Company of Acadia (Compagnie de la Peche Sedentaire) to protect the fishery. The principal ports were at Chedabucto Bay, which accounted for fifty fishers in 1686. Dauphin de Montorgueil was the commandant at Fort Saint-Louis.
Just before the outbreak of King William's War, Gabriel Gautier erected a small fort and fishing establishment (1686). It had two buildings, 60 X 20 feet each, defended by four cannon. There were 150 residents, of whom 80 were fishermen. A detachment of regular troops was eventually stationed at the fort.
In 1687 there were 150 persons at Chedabouctou, 80 of whom were fishermen. The Company of Acadia suffered heavy losses in 1688, when Chedabouctou was pillaged by New Englanders.
During King William's War, in 1690, Captain Cyprian Southack proceeded to Chedabucto to take Fort St. Louis which, unlike Port Royal, Nova Scotia, put up a fight before surrendering. As part of Sir William Phips expedition to destroy the capital of Acadia Port Royal, Phips sent Southack to Chedabacto with 80 men to destroy Fort St. Louis and the surrounding French fishery. Meneval was stationed at the fort with 12 soldiers. They tried to defend the fort for over six hours, until fire bombs burned the fort to the ground. Southack destroyed the enormous amount of 50, 000 crowns of fish.
