Wongunk Chief Sequin Attacks Wethersfield with Assistance from Pequot

Through the fall and winter, Fort Saybrook was effectively besieged.

Any who ventured outside were killed. As spring arrived in 1637, the Pequot stepped up their raids on Connecticut Colony towns. On April 23, Wongunk chief Sequin attacked Wethersfield with Pequot help, killing six men and three women, a number of cattle and horses, and taking captive two young girls (the daughters of Abraham Swain, later ransomed by Dutch traders). In all, the towns lost about 30 settlers.

A punitive expedition, led by John Endicott, enraged the Pequots. They retaliated by raiding the unsuspecting settlement of Wethersfield on 23 April 1637. Thirty settlers were killed and two girls were kidnapped. They tortured many of their victims, as was the custom of some Eastern tribes, and reinforced their reputation for cruel savagery.
