By the beginning of 1691, the French in Quebec had prepared to take the offensive. Governor Frontenac's raids on the English colonies and successful defence of Quebec in 1690 had eliminated the possibility of any further English attacks on Canada.
In 1692, Governor de Villebon reoccupied Port Royal. He immediately began to organize militia and Abenaki warriors for raids on English settlements. Between 1692 and 1694, de Villebon's raiding parties terrorized Maine and New Hampshire. The Abenaki destroyed the towns of Oyster Bay, York, and Wells.
D'Iberville continued his daring exploits. He led militia raids into New Hampshire then embarked upon another expedition to Hudson Bay. By 1695, d'Iberville's force had seized all but one of the English forts on Hudson Bay. Fort Albany was the only post to elude him. In 1696, he conquered Newfoundland with a force of 125 Canadian militia. Bonavista was the only part of Newfoundland that remained in English hands.
Governor Frontenac personally commanded the French forces for the final offensive against the Iroquois Confederacy (the Five Nations-Mohawk, Seneca, Onondaga, Cayuga, and Oneida) in 1696. He led a force of 2,000 Troupes de la Marine, militia, and Native allies into Oneida and Onondaga territory. The French force inflicted heavy losses on the Iroquois and devastated their lands. The only French losses in the campaign were four killed.
The French and English signed the Treaty of Ryswick on 20 September 1697. The French gained all of the forts and trading posts in Hudson Bay, retained control of Newfoundland, and had their occupation of Port Royal confirmed. One year later, the Iroquois negotiated a treaty with the French. In it, they recognized French control of the area north of the Great Lakes and the alliances with the First Nations to the west.
During the war, the Canadian militia became a seasoned and highly skilled combat force. The Troupes de la Marine had originally been organized and trained to fight as regular troops, but, by 1697, they had also mastered the techniques of la petite guerre (guerrilla warfare).
