In 1746, the fort was the site of the
Siege of Fort Massachusetts, a battle in
King George's War between the 21 militiamen garrisoning the fort and almost a thousand French soldiers and their Indian allies that resulted in the burning of the fort and the capture of the garrison and their families. The twenty-nine captives were taken to Quebec to be later exchanged as prisoners of war; only fourteen, ten men and four children, lived to be traded back to the British colonies a year later. The Reverend John Norton was among those who returned alive and he published a captivity narrative of the events titled "The Redeemed Captive." According to Norton, Captain Williams was away on business and around half the soldiers were ill at the time of the attack. Surrounded by so many forces, it was deemed impossible for a messenger to get through and ride to the fort at
Deerfield for reinforcements. The Massachusetts militia held the fort for 36 hours before surrendering to the French captain due to lack of shot and gunpowder. Their terms of surrender were that they should be prisoners of the French only, that children be allowed to remain with their families and that they be exchanged at the first possible opportunity. The first term was not heeded, but in Norton's account, they were not treated with cruelty and Indian troops carried those who were too sick or wounded to walk. ==Later colonial history==
