# The Killing of Colonel Ledyard After Surrender at Fort Griswold, 1781

On September 6, 1781, in the final months of the American Revolutionary War, one of the conflict's most infamous acts of violence took place on a hilltop overlooking the Thames River in Groton, Connecticut. Colonel William Ledyard, a militia commander who had organized the defense of Fort Griswold against a powerful British assault force, was killed after attempting to surrender his garrison in accordance with the accepted conventions of eighteenth-century warfare. The manner of his death — reportedly stabbed with his own sword by the very officer to whom he offered it — shocked the region and became a rallying symbol of British cruelty that would resonate for generations.

The events of that day unfolded against the backdrop of a British raid on the port town of New London, just across the river from Groton. The raid was commanded by Brigadier General Benedict Arnold, the former Continental Army hero who had defected to the British cause the previous year. Arnold's objective was to destroy the supplies, warehouses, and privateering vessels that made New London a thorn in British naval operations. While Arnold led one column against New London itself, a second force was directed across the river toward Groton Heights, where Fort Griswold stood as the primary defensive fortification guarding the eastern bank of the Thames.

Fort Griswold was a stone-walled fortification garrisoned that day by a collection of local militia and volunteers, numbering perhaps 150 to 170 men. Colonel William Ledyard, a respected local militia officer from Groton, commanded the defense. Though Ledyard and his men were outnumbered by the several hundred British regulars and Loyalist troops advancing on the fort, they mounted a fierce and determined resistance. The attackers suffered heavy casualties as they attempted to scale the walls, and the fighting was brutal and close-quartered. Among the British losses were several officers, including Major William Montgomery, who was killed during the assault on the walls. The intensity of the British casualties would later be cited as a factor in the violence that followed.

When the British finally overwhelmed the defenses and poured into the fort, Colonel Ledyard reportedly recognized that further resistance was futile and moved to surrender. According to the consistent testimony of multiple American survivors and witnesses, Ledyard approached a British officer and offered his sword — a customary and universally understood gesture of formal capitulation. The officer, whose precise identity has been the subject of historical debate, reportedly asked who commanded the fort. When Ledyard identified himself, the officer took the proffered sword and drove it through Ledyard's body, killing him. What followed was a period of intense violence in which many of the American defenders were killed or wounded even after resistance had ceased. Survivors described a scene of carnage that went far beyond the bounds of legitimate combat.

The killing of Colonel Ledyard became the defining atrocity of the Battle of Groton Heights. British accounts from the period either disputed the details of the incident or sought to minimize its significance, sometimes attributing the post-surrender violence to the chaos and fury that followed a costly assault rather than to deliberate intent. However, the American testimony — drawn from surviving defenders, townspeople who witnessed the aftermath, and subsequent investigations — was remarkably consistent, and most historians regard the core narrative as reliable. The identity of the specific officer who killed Ledyard remains uncertain, though several names have been put forward in various accounts over the years.

The event mattered deeply in the broader story of the Revolutionary War for several reasons. It occurred at a moment when the war was moving toward its conclusion — just weeks before the decisive Siege of Yorktown — and it reinforced American resolve at a critical time. The killing of a surrendering officer violated the fundamental codes of honor and conduct that governed eighteenth-century warfare, making it not merely an act of battlefield violence but a breach of the moral framework that both sides ostensibly recognized. The incident gave Americans powerful propaganda and deepened the animosity toward Benedict Arnold, whose name was already synonymous with betrayal and who bore overall command responsibility for the raid. In Connecticut, the memory of Colonel Ledyard's death and the massacre at Fort Griswold became a lasting part of the region's identity, eventually commemorated by the Groton Monument, a granite obelisk erected in the nineteenth century that still stands on the site today, bearing the names of those who fell in defense of the fort.
