Chevalier de Baugy arrived at Quebec in 1682 and immediately became involved in the fur trade of the Great Lakes; namely, putting an end to the dominant position of Cavelier de La Salle in that area.
Despite limited ammunition and provisions, the defenders withstood three assaults, and the Iroquois were forced to abandon their attacks and withdraw the way they had come.
In 1685, La Salle was given back control of Fort Saint Louis by the French king.
De Baugy took part in at least one more campaign in Canada, in 1687 with Denonville against the Senecas.
De Baugy, as Denonville's aide-de-camp, left a valuable journal of his experiences during the expedition.
