Why Groton Matters

The Blood of Groton Heights: How a Small Connecticut Town Became the Site of the Revolution's Most Brutal Massacre

On the morning of September 6, 1781, the residents of Groton, Connecticut, could see the British fleet approaching from across the Thames River. Within hours, their town would become the site of one of the most savage episodes of the entire American Revolution — a massacre that killed scores of defenders who had already surrendered, claimed the life of their commanding officer with his own sword, and left a community so devastated that nearly every household lost a father, brother, or son. The Battle of Fort Griswold and its aftermath represent not merely a military engagement but a profound story of courage, betrayal of the rules of war, and a community's agonizing recovery. That the attack was led by Benedict Arnold — Connecticut's own native son turned traitor — only deepened the wound. Groton's Revolutionary War history is among the most dramatic and underappreciated in the entire founding story of the United States.

To understand what happened at Groton, one must first understand the strategic importance of the Thames River and the twin towns that flanked it. New London, on the western bank, was one of Connecticut's busiest ports and a haven for American privateers who had been wreaking havoc on British shipping throughout the war. Groton, on the eastern bank, was a modest community of farmers, fishermen, and tradesmen, but it occupied high ground — Groton Heights — that commanded the river's approach. As early as 1774, recognizing the growing tensions with the Crown, Connecticut authorities ordered the fortification of the position that would become Fort Griswold. The fort was a rough but serviceable stone-and-earth work, roughly square in plan, with walls reaching several feet high and defended by a dry ditch and abatis. It was never a grand fortification, but it was designed to make any attacker pay dearly for an assault, and in this grim purpose it would succeed beyond anyone's expectation.

By the late summer of 1781, the war had reached a decisive phase. Washington and Rochambeau were marching their combined forces southward toward Virginia, where Cornwallis was entrenching at Yorktown. To create a diversion and draw American attention northward, the British high command dispatched Benedict Arnold — now a brigadier general in the King's service — with approximately 1,700 troops to raid the Connecticut coast. Arnold knew the region intimately; he had grown up in nearby Norwich and understood exactly where the vulnerabilities lay. His target was the privateering fleet and the stores of goods in New London, but to secure both banks of the river, he divided his force. Arnold personally led the assault on New London from the west, while a detachment of approximately 800 regulars, including elements of the 40th and 54th Regiments of Foot along with Loyalist units, crossed to the Groton side under the overall direction of Lieutenant Colonel Edmund Eyre, with Major William Montgomery commanding a key assault column against Fort Griswold itself.

Inside the fort, the situation was desperate from the start. Colonel William Ledyard, a respected local militia officer and member of one of Groton's leading families, commanded the defense. Despite frantic efforts to rally the countryside, Ledyard could muster only about 150 to 170 defenders — a mix of militia, townsmen, and a handful of Continental veterans. Among them were men whose names deserve remembrance: Captain Lambert Avery, who led one of the militia companies; Lambert Latham, known as "Lambo," a steadfast soldier who would fight to the last; and Jordan Freeman, a free Black man who took his place among the defenders as an equal, musket in hand, prepared to die for the cause of liberty that the Revolution professed but so imperfectly practiced. Freeman's presence at Fort Griswold is one of the most significant and poignant facts of the battle, a testament to the reality that Black Americans fought and bled for the nation's independence even when that nation had not yet reckoned with the full meaning of its own ideals.

The British assault began in the early afternoon. The attackers advanced from three sides, and the defenders poured devastating fire into their ranks. The fighting was ferocious. As the British attempted to scale the walls, the garrison used bayonets, pikes, and anything at hand to hurl them back. It was during one of these repulses that Jordan Freeman achieved an act of extraordinary valor: as Major William Montgomery mounted the parapet and called for the garrison to surrender, Freeman drove a pike or spear through him, killing him on the spot. Montgomery's death only inflamed the attacking force. The British eventually forced their way through the fort's gate and over the walls, and the fighting became hand-to-hand slaughter within the confined space of the works.

What followed is the event that seared Groton into Revolutionary War memory. As the British overwhelmed the garrison, Colonel Ledyard recognized that further resistance was futile and ordered his men to cease firing. According to multiple survivor accounts and the tradition that grew from them, Ledyard offered his sword to the senior British officer present — likely Major Stephen Bromfield, who had assumed command after Montgomery's death — in the customary gesture of formal surrender. What happened next violated every accepted convention of eighteenth-century warfare: the officer reportedly took Ledyard's sword and plunged it through his body, killing the colonel with his own weapon. This act of murder under a flag of surrender became the defining atrocity of the battle.

But the killing did not stop with Ledyard. In a frenzy of rage — fueled by their heavy casualties and Montgomery's death — the British troops turned on the disarmed garrison. Survivors described a scene of indiscriminate butchery. Men who had thrown down their weapons were bayoneted where they stood or as they tried to flee. Lambo Latham was among those killed in this phase of the slaughter, cut down after resistance had ceased. Jordan Freeman, too, was slain, though the precise circumstances of his death amid the chaos remain debated. In all, approximately 85 of the garrison were killed and perhaps 35 to 40 more were wounded, many grievously. Of the roughly 150 defenders, the casualty rate approached an almost unimaginable eighty percent.

The treatment of the wounded added yet another layer of horror to the day. According to well-attested accounts, the British loaded many of the injured survivors onto a wagon or ammunition cart and sent it rolling down the steep slope of Groton Heights toward the river. The cart reportedly gained speed on the rough hillside, jolting and battering the wounded men inside. Whether this was a deliberate act of cruelty or a callous expedient has been debated for over two centuries, but for the people of Groton, the meaning was plain: the attackers showed no mercy even to men who could no longer fight.

Across the river, Arnold's forces had put New London to the torch, and great columns of smoke rose over the harbor as warehouses, ships, and homes burned. But it was on the Groton side that the day's true cost was measured in human terms. When the British finally withdrew to their ships, the people of Groton emerged to reclaim their dead. The scene at Fort Griswold was appalling. Families came to the fort and carried their slain home on doors, shutters, and improvised litters. In a community as small as Groton, the losses were catastrophic — virtually every family was touched. The days that followed were consumed with burials, with tending to the maimed survivors, and with a grief so pervasive that it reshaped the community's identity for generations.

One story from the aftermath has endured as a symbol of Groton's defiant spirit. Anna Bailey, a local woman, is remembered for bringing flannel petticoats and other cloth to the fort to be used as wadding for the cannons or bandages for the wounded. Whether the details of her contribution have been embellished by time, her story represents the broader truth that the defense of Groton was a community effort, sustained by women, children, and the elderly who supported the men inside the walls.

The massacre at Fort Griswold established Groton's identity as a place of maritime defense and sacrifice, a legacy that persisted through subsequent conflicts and ultimately contributed to the town's long association with military and naval installations. In 1830, the people of Connecticut erected the Groton Monument — a granite obelisk rising 134 feet above Groton Heights — to honor those who fell on September 6, 1781. It remains one of the earliest monumental commemorations of the Revolution in the United States, and the names inscribed on its base constitute a roll call of ordinary men who gave everything for their country's cause.

What makes Groton distinctive in the broader Revolutionary story is the convergence of themes that the modern era finds most urgent. The massacre raises questions about the laws of war and the treatment of prisoners that remain relevant in any century. Jordan Freeman's sacrifice compels us to confront the role of Black Americans in winning a freedom that was not extended to all. The community's mourning and recovery remind us that the cost of war is borne not only by soldiers but by entire communities — by the wives who became widows, the children who grew up fatherless, and the neighbors who rebuilt from devastation.

For modern visitors, students, and teachers, Groton offers something that few Revolutionary War sites can match: an intimate, human-scaled tragedy that makes the Revolution's cost viscerally real. Fort Griswold Battlefield State Park preserves the ground where these events occurred, and walking the earthworks, standing where Ledyard was murdered and Freeman fought, one is brought face to face with the Revolution not as a story of abstract ideals but as an experience of blood, loyalty, and loss. This is sacred ground — not because of victory, but because of the price that was paid. Groton asks us to remember that the American Revolution was not won cheaply, and that its promises are still, in many ways, unfinished.
