Fort Griswold Battlefield State Park

The site of the September 6, 1781 Fort Griswold Massacre, one of the bloodiest single engagements in Connecticut's Revolutionary War history. The restored earthwork fort, monument obelisk, and museum interpret the battle in which approximately 165 American defenders held the fort against 800 British troops under Lt. Col. Edmund Eyre, ultimately surrendering after Col. William Ledyard was killed — reportedly with his own sword — and 88 defenders were massacred. The earthworks and ditch are substantially intact.
