For King William's War, neither England nor France thought of weakening their position in Europe to support the war effort in North America. New France and the Wabanaki Confederacy were able to thwart New England expansion into Acadia, whose border New France defined as the Kennebec River in southern Maine. According to the terms of the 1697 Treaty of Ryswick that ended the Nine Years' War, the boundaries and outposts of New France, New England, and New York remained substantially unchanged.
