The Kennebec River valley was attacked and burned in 1676 during King Philip's War, then again in 1689 at the outset of King William's War, and was not resettled until after the 1713 Treaty of Portsmouth. The town of Newtown-on-Arrowsic was rebuilt in 1714 on the southern end of Arrowsic Island, which was incorporated in 1716 by the Massachusetts General Court as Georgetown-on-Arrowsic, named for Fort St. George. The town's boundaries were extended to encompass Parker's Island, Woolwich, Phippsburg and Bath (which included West Bath). Abandoned during Dummer's War and beleaguered during the French and Indian Wars, the region resettled slowly in the 1750s until peace was assured with the 1759 Fall of Quebec.
