The Raid on Dover, also known as the Cochecho Massacre, was a military clash between the Native Americans and the settlers which took place in Dover, New Hampshire, on June 27–28, 1689. The uprising was led by Chief Kancamagus and caused King William's War, a series of cruel Indian massacres orchestrated by Jean-Vincent d'Abbadie de Saint-Castin and Father Louis-Pierre Thury.
