The siege of Pemaquid occurred during King William's War when French and Native forces from New France attacked the English settlement at Pemaquid (present-day Bristol, Maine), a community on the border with Acadia. The siege was led by Pierre Le Moyne d'Iberville and Baron de St Castin between August 14–15, 1696. Commander of Fort William Henry, Captain , surrendered the fort. Iberville killed three of the soldiers and sent the other 92 back to Boston.
