Louisiana Motte’s company was almost immediately dispatched to fortify the southern flank of New France. They built a trail connecting Fort Sainte Thérèse and Fort Saint-Louis (Chambly).
In 1666, the company built a fort on a small island overlooking the northern end of the "Iroquois Lake," today’s Lake Champlain. The fort was garrisoned by about 300 French soldiers over the next four years, after which time the troops were pulled back to Québec.
Before retreating, the fort was destroyed by the French soldiers.
