New York City in the Revolution: Battleground, Prison, and Birthplace of a Nation

Few American cities bore the weight of the Revolutionary War as heavily, or as long, as New York. From the summer of 1776, when George Washington's Continental Army suffered its most devastating defeat on the fields of Brooklyn, to November 1783, when the last British soldiers sailed out of the harbor on what New Yorkers would celebrate for generations as Evacuation Day, the city endured more than seven years of enemy occupation — longer than any other place in the thirteen colonies. New York was not merely a backdrop to the Revolution; it was a strategic prize, a killing ground, a nest of spies, and ultimately the stage on which the new republic announced itself to the world. To understand the American Revolution without understanding what happened in New York is to read only half the story.

The British recognized what Washington also understood: whoever controlled New York controlled the Hudson River, and whoever controlled the Hudson could sever New England from the rest of the colonies. This geographic reality made the city the most strategically consequential piece of terrain on the continent. In the spring and summer of 1776, Washington moved his army south from Boston, where he had successfully forced a British evacuation in March, to fortify Manhattan and the surrounding heights. He knew the British were coming. What he could not have fully anticipated was the scale of what arrived. In late June and throughout July, a massive British armada — more than four hundred ships carrying approximately 32,000 troops under General Sir William Howe, supported by his brother Admiral Richard Howe's naval forces — assembled in New York Harbor and on Staten Island. It was the largest expeditionary force Britain had ever sent abroad, and the sight of it filling the harbor must have been terrifying to the roughly 19,000 Continentals tasked with defending the city.

The blow fell on August 27, 1776, at the Battle of Long Island — also known as the Battle of Brooklyn — the first major engagement fought after the Declaration of Independence. Howe landed his forces on the southwestern shore of Long Island and executed a brilliant flanking maneuver through the unguarded Jamaica Pass, rolling up the American left and driving Washington's troops back toward the fortified positions on Brooklyn Heights. The result was a catastrophe for the Continental Army. Roughly 1,000 Americans were killed, wounded, or captured in a single day; the Maryland 400, a regiment that mounted a suicidal rearguard action to cover the retreat, was nearly annihilated. Washington, watching from a redoubt on the Heights, reportedly said, "Good God, what brave fellows I must this day lose!" Only a desperate nighttime evacuation across the East River on August 29–30, carried out in fog and silence by Massachusetts fishermen under Colonel John Glover, saved the army from total destruction. It was one of the most remarkable retreats in military history, and it preserved the Revolution itself — but New York was effectively lost.

What followed was a series of further disasters. On September 15, British forces landed at Kip's Bay on Manhattan's east side, scattering the American militia defenders so thoroughly that Washington, in a rare loss of composure, reportedly struck fleeing soldiers with the flat of his sword and had to be pulled from the field by his aides. The Americans fell back to Harlem Heights, where a sharp engagement the following day restored some measure of morale, but the broader situation was grim. On September 21, a massive fire — the Great Fire of New York — consumed roughly a quarter of the city's buildings. The cause has never been definitively established; the British suspected American arson, and several suspected incendiaries were reportedly killed by soldiers and civilians in the chaos. Washington, who had considered burning the city himself before Congress forbade it, privately admitted he was not sorry to see it in ashes. The fire left thousands homeless and scarred the cityscape for the duration of the occupation.

It was in this atmosphere of defeat and suspicion that one of the Revolution's most poignant martyrdoms occurred. Captain Nathan Hale, a twenty-one-year-old Yale graduate serving in Knowlton's Rangers, had volunteered to cross into British-held territory on Long Island to gather intelligence on enemy positions. He was captured on September 21, the same night as the Great Fire, and brought before General Howe. Found with incriminating documents hidden on his person, Hale was condemned to hang without trial. On the morning of September 22, 1776, he was executed, reportedly declaring — in words that became immortal whether or not they are perfectly transcribed — "I only regret that I have but one life to lose for my country." He was denied a clergyman and a Bible. His letters to his family were destroyed by his captors. Hale's death became a powerful symbol of patriot sacrifice, though it also underscored the grim reality that espionage in New York was a deadly business on both sides.

The fall of Fort Washington on November 16, 1776, completed the British conquest of Manhattan. Nearly 2,900 American soldiers were captured in the fort's surrender — one of the largest mass captures of the war. Among the defenders was Margaret Corbin, a remarkable woman who had followed her husband John into service as a camp follower. When John Corbin was killed manning a cannon during the British assault, Margaret took his place at the gun, continuing to fire until she was severely wounded by grapeshot that mangled her left arm and tore into her chest. She survived, became one of the first women to receive a military pension from the Continental Congress, and is buried today at the United States Military Academy at West Point. Her courage at Fort Washington stands as a testament to the countless women whose contributions to the Revolution have been too often overlooked.

For the thousands of Americans captured at Fort Washington, Long Island, and elsewhere, a nightmare awaited. The British, overwhelmed by prisoners and largely indifferent to their suffering, confined captured soldiers in churches, sugar houses, and — most infamously — aboard decommissioned vessels anchored in Wallabout Bay, off the Brooklyn shore. The prison ships, of which the HMS Jersey became the most notorious, were floating charnel houses. Packed below decks with minimal food, contaminated water, and no sanitation, prisoners died of disease, starvation, and exposure at staggering rates. Estimates of the total dead vary, but credible scholarship places the figure at approximately 11,500 — more Americans than died in all the battles of the Revolution combined. Each morning, the British guards would call down the hatchways: "Rebels, turn out your dead." The bodies were buried in shallow graves along the Brooklyn shoreline, where bones continued to wash out of the sand for decades. Today, the Prison Ship Martyrs' Monument in Fort Greene Park stands over a crypt containing their remains — the largest memorial to the Revolutionary War dead in the United States, and one of the least visited.

Throughout the occupation, New York became a divided city: a Loyalist stronghold on the surface, but threaded with patriot intelligence networks that provided Washington with critical information. Among the most effective of these secret agents was Hercules Mulligan, an Irish-born tailor whose shop on Queen Street (now Pearl Street) catered to British officers. Mulligan, a Son of Liberty who had helped recruit Alexander Hamilton to the patriot cause, used his access to British clientele to gather intelligence on troop movements and planned operations. He is credited with providing information that twice saved Washington's life. His role remained secret until after the war, when Washington himself publicly acknowledged Mulligan's service by making the tailor's shop his first social visit after the British evacuation.

That evacuation came on November 25, 1783, more than two months after the Treaty of Paris formally ended the war. As the last British troops withdrew from their positions at the southern tip of Manhattan, Washington and Governor George Clinton led the Continental Army into the city in a triumphal procession. Legend holds that a British soldier, in a final act of contempt, greased the flagpole at Fort George and nailed the Union Jack to it; a young sailor reportedly climbed the pole, tore down the British flag, and raised the Stars and Stripes. The day was celebrated as Evacuation Day in New York for over a century, until it was gradually eclipsed by Thanksgiving. On December 4, 1783, Washington gathered his officers at Fraunces Tavern near the Battery for an emotional farewell. "With a heart full of love and gratitude, I now take leave of you," he told them, embracing each man in turn. The scene, recorded by Colonel Benjamin Tallmadge, remains one of the most moving moments of the entire revolutionary era.

New York's revolutionary story did not end with the war. On April 30, 1789, Washington stood on the balcony of Federal Hall at the corner of Wall and Broad Streets and took the oath of office as the first President of the United States, with New York serving as the nation's first capital. And in the early morning hours of July 11, 1804, on a narrow ledge in Weehawken, New Jersey, just across the Hudson from Manhattan, Alexander Hamilton — Washington's former aide-de-camp, the architect of the nation's financial system, and New York's most consequential citizen — fell mortally wounded in a duel with Vice President Aaron Burr. He died the following afternoon in a friend's home in Greenwich Village. Hamilton's death, though it occurred after the revolutionary generation had moved into the era of governance, was a final violent echo of the personal rivalries and political passions that the Revolution had unleashed.

Modern visitors to New York City walk daily over ground that is saturated with revolutionary history, though almost nothing of the eighteenth-century cityscape survives. Fraunces Tavern still stands at the corner of Pearl and Broad Streets, rebuilt and reimagined but occupying its original site. Federal Hall National Memorial marks where Washington took the oath. The Prison Ship Martyrs' Monument rises above Fort Greene Park. For students, teachers, and anyone seeking to understand how the American nation was forged, New York offers something no other city can: the full arc of the revolutionary experience, from catastrophic defeat to resilient resistance to ultimate triumph, all within the compass of a single extraordinary place. The Revolution was not won in New York — but it was very nearly lost there, and the republic was born on its streets.
