The Pequot were an Algonquin tribe of North American Indians occupying eastern Connecticut where they lived by hunting, fishing, gathering and raising maize. They entered into a treaty with the colonists at Boston in 1634, but soon became hostile. Expeditions were sent against them and they in turn attacked Wethersfield and killed many settlers. In 1637, an expedition under Mason surprised the Indians at a fort near the present Groton, Connecticut. A desperate struggle followed in which the Indians were overcome with great loss. The remnant was nearly annihilated in a subsequent battle at Fairfieldswamp. Many were sent as slaves to the West Indies. A few survived and obtained two land grants from the British. One surviving group operates a successful casino today at Ledyard. Research Pequot
