The Cherry Valley massacre was an attack by British and Iroquois forces on Fort Alden and the village of Cherry Valley on November 11, 1778. It has been described as one of the most horrific frontier massacres of the war. A mixed force of Loyalists, British soldiers, Seneca and Mohawks descended on Cherry Valley, whose defenders, despite warnings, were unprepared for the attack. During the raid, the Seneca in particular targeted non-combatants, and reports state that 30 such individuals were slain, in addition to a number of armed defenders.
Marker is within the Cherry Valley Cemetery on Alden Street. Further interpretation on the Cherry Valley Massacre can be found at the Cherry Valley Museum.
