In the early hours, a combined force of Puritan militia under Captain John Mason and allied Narragansett and Mohegan warriors set fire to a fortified Pequot settlement, killing an estimated 400 to 700 people as they tried to flee the flames. The massacre broke Pequot power in southern New England and marked one of the earliest and deadliest atrocities of colonial warfare against Native Americans in North America.
The Pequot War had simmered for months over trade disputes, competition for wampum production, and escalating colonial encroachment on Native land in the Connecticut River Valley. Before dawn on May 26, 1637, Captain John Mason led roughly ninety Puritan militia alongside several hundred Narragansett and Mohegan allies to the fortified Pequot village at Mystic, expecting to find and battle warriors.
Instead they found the village filled largely with women, children, and the elderly, most of the Pequot fighting men being elsewhere. Mason ordered the wigwams set ablaze and stationed men around the palisade to cut down anyone attempting to escape the flames. Colonial accounts, including Mason's own later writing, described the slaughter almost approvingly, with one witness estimating between 400 and 700 Pequot dead in under an hour—a toll that horrified even some of the allied Narragansett warriors watching.
The attack effectively shattered Pequot political and military power in the region. Survivors were killed, enslaved, or absorbed into other tribes, and the Pequot as a distinct polity nearly ceased to exist for generations. The massacre stands as one of the starkest early examples of the asymmetric brutality that would characterize centuries of colonial warfare in North America.
