In August 1675, King Philip's War reached central Massachusetts. Brookfield, one of the most isolated settlements in the colony, was attacked by Nipmuck forces. After an ambush the town was besieged. For two days the townsfolk, consisting of 80 people, sought shelter in the garrison house while the rest of the town was completely destroyed. The settlement lay abandoned for twelve years.
During the winter of 1776, General Henry Knox passed through the town with cannon from Fort Ticonderoga to end the Siege of Boston.
