Battle of Groton Heights

Battle of Groton Heights. Fought on September 6, 1781, this engagement was a significant and brutal raid conducted by British forces under the command of the American traitor Benedict Arnold against the Connecticut ports of New London and Groton. The battle is most infamous for the storming of Fort Griswold, where the American garrison, commanded by Lieutenant Colonel William Ledyard, was massacred after surrendering. Occurring just weeks before the decisive Siege of Yorktown, the attack demonstrated the continued vulnerability of the American coastline and remains one of the war's most notorious episodes of violence.

Background

In the late summer of 1781, British strategy in the American Revolutionary War aimed to divert American attention and resources from the main theater in Virginia. The former American general Benedict Arnold, now a British brigadier general, proposed a raid on the prosperous privateering port of New London in his native Connecticut. New London and its twin port across the Thames River, Groton, were defended by two forts: Fort Trumbull on the New London side and the more formidable Fort Griswold on Groton Heights. The region's defenses were undermanned, primarily consisting of local Connecticut Militia under commanders like Lieutenant Colonel William Ledyard. British command, including General Sir Henry Clinton, authorized the expedition, which sailed from New York City with a force of regulars from the 40th (the 2nd Somersetshire) Regiment of Foot, Loyalist units like the American Legion, and Hessian jägers.

Battle

On the morning of September 6, Arnold's fleet of over 30 ships divided its forces. Arnold led approximately 800 men ashore on the New London side, quickly capturing the undermanned Fort Trumbull and entering the town, which was subsequently set ablaze. The main American resistance centered on Fort Griswold, a star-shaped earthwork on Groton Heights garrisoned by about 150 militiamen under William Ledyard. British Lieutenant Colonel Edmund Eyre led the assault on the fort with a much larger force. After initial attacks were repulsed with heavy British casualties, including the death of Major William Montgomery, the British breached the walls. Accounts differ, but upon the American surrender, Ledyard reportedly offered his sword to the British officer in command, who then used it to kill him, triggering a massacre of the surrendering garrison by enraged British and Hessian troops. The fighting was exceptionally fierce, with many Americans bayoneted inside the fort.

Aftermath

The aftermath of the battle was one of devastation and shock. British casualties were significant, with nearly 200 men killed or wounded, while American losses at Fort Griswold were catastrophic, with approximately 85 of the 150 defenders killed and most of the rest wounded. The towns of New London and Groton were left in smoldering ruins, with numerous ships and warehouses destroyed. Arnold, having achieved his military objective, withdrew his forces back to New York City by September 8. The brutality of the massacre at Fort Griswold, widely reported in American newspapers like the Pennsylvania Packet, fueled intense propaganda and deep hatred for Benedict Arnold, solidifying his reputation as a traitor and butcher. The raid failed in its strategic aim to relieve pressure on Lord Cornwallis's army in Virginia, which would surrender at the Siege of Yorktown just over a month later.

Legacy

The legacy of the battle is preserved as a powerful symbol of patriotic sacrifice and British atrocity. The site of Fort Griswold is now the Fort Griswold Battlefield State Park, a designated National Historic Landmark managed by the Connecticut Department of Energy and Environmental Protection. The Groton Monument, a 135-foot stone obelisk erected in 1830, and the adjacent Museum commemorate the defenders. The battle is often cited alongside similar brutal actions like the Baylor Massacre and the Waxhaws Massacre. Annual ceremonies are held by organizations such as the Sons of the American Revolution and the Daughters of the American Revolution. The event remains a poignant chapter in Connecticut's history, detailed in works by historians like William Fowler and is a focal point for local heritage in New London County.
