Charleston and the American Revolution: A City Besieged, Occupied, and Reborn

Charleston, South Carolina, occupies a singular place in the story of American independence — not as a backdrop to a single dramatic battle, but as a city that experienced the full, brutal arc of revolutionary warfare. It was the site of one of America's earliest and most inspiring victories, the scene of the Continental Army's most catastrophic defeat, a city subjected to more than two years of British military occupation, and ultimately a place where the meaning of liberty was tested and contested by every segment of its diverse population. No other American city endured so sustained and consequential a role in the Revolutionary War, and no understanding of the conflict is complete without reckoning with what happened on the peninsula between the Ashley and Cooper Rivers.

Charleston — known as Charles Town or Charlestown during the Revolution — was one of the most important cities in colonial America: the fourth largest in the colonies, with about 12,000 inhabitants.

By the mid-eighteenth century it had become a bustling trade center and the wealthiest and largest city south of Philadelphia. Rice and indigo had been successfully cultivated by gentleman planters in the surrounding coastal lowcountry, while merchants profited from the successful shipping industry. The city had been the political, economic, and cultural center of the colony from its founding in 1670.

Charleston was also the hub of the Atlantic slave trade in the colonies — enslaved people constituted about half of the city's population, and until the end of the slave trade, Charleston's customs processed about 40 percent of the enslaved Africans brought to North America. Sullivan's Island, the sandy spit guarding the entrance to Charleston Harbor, served as a quarantine station through which enslaved Africans were processed before being sold in the city. This immense wealth, built on the labor of enslaved people, made Charleston a strategic prize of the highest order.

Charleston's revolutionary ferment did not begin on the battlefield; it began in the streets and meeting halls. In the autumn of 1766, following the repeal of the Stamp Act, twenty-six men gathered under the branches of an ancient live-oak tree just outside urban Charleston to share a light meal and discuss political matters. They were skilled tradesmen — blacksmiths, carpenters, wheelwrights, coopers, and shipwrights — who made their living by laboring with their hands and tools.

Christopher Gadsden delivered an address encouraging them to defend their rights against all foreign taxation, and joining hands around the tree, they associated themselves as defenders and supporters of American Liberty; from that time the oak was called Liberty Tree, and public meetings were occasionally held there.

When the news of the Declaration of Independence finally reached Charleston in August 1776, it was read publicly under the tree's branches.

On December 1, 1773, the ship London sailed into Charleston Harbor carrying 257 large chests of East India Company tea consigned to merchants Roger Smith, Peter Leger, and William Greenwood. The tea was mostly the bohea variety — nearly 70,000 pounds of East India Company product ready to be taxed and sold.

The next day, concerned Charlestonians posted notices and circulated handbills inviting all inhabitants to assemble in the Great Hall of the Exchange Building at 3:00 in the afternoon of December 3. Colonel George Gabriel Powell, a fair-minded and respected member of the colonial assembly from the South Carolina backcountry, was selected to chair the community meeting and the ones to come, as debates continued for months. So many Charlestonians from a variety of social classes crammed into the elegant room that the beams and floorboards began to creak and groan. The consignees, pressured by Christopher Gadsden and others, agreed not to accept the tea. By December 3, the assembled group resolved not to pay the duty on the tea, which forced the boat and its contents to sit unclaimed in the harbor. After twenty days unclaimed, customs officials seized the tea and stored it in the basement of the Exchange Building. Though less dramatic than the Boston Tea Party, which occurred just weeks later on December 16, Charleston's protest sent a clear message: South Carolinians would not submit to parliamentary taxation without their consent. In 1776, patriot leaders sold the confiscated tea to help finance South Carolina's participation in the Revolution.

The First Battle: Sullivan's Island, June 28, 1776

The first major test of Charleston's defenses came in the summer of 1776. The British, seeking to gain a foothold in the southern colonies, organized an expedition under General Henry Clinton and Admiral Sir Peter Parker. In early January 1776, the Charles Town Council of Safety ordered the construction of a fortification on Sullivan's Island, the sandy barrier island at the entrance to Charleston Harbor. Colonel William Moultrie and his 2nd South Carolina Regiment arrived on the island in March 1776 and began building the fort. The structure was planned as a square redoubt with bastions at each corner, its walls constructed of an inner and outer layer of palmetto logs up to twenty feet in height, with the sixteen-foot space between them filled with sand. When the main British fleet arrived outside Charleston Harbor on June 1, the fort remained unfinished — only the seaward face was complete. General Charles Lee, the Continental commander for the southern district, inspected the incomplete fort and recommended it be abandoned, calling it a "Slaughter Pen." Acting on Moultrie's advice, Governor John Rutledge refused.

On June 28, 1776, at approximately 10:30 in the morning, the British launched their naval assault. In the ten-hour battle that followed, the British navy aimed nearly 300 cannon at Fort Sullivan and fired more than 50 tons of iron shot. The Americans inside the unfinished fort had just 31 cannon and expended roughly two-and-a-half tons of gunpowder — outmatched by a ratio of nearly eight to one. But the spongy, fibrous palmetto logs proved remarkably resilient, absorbing the cannon fire rather than splintering like conventional timber. The American defenders, including an additional eighty Catawba fighters who served alongside Moultrie's men as riflemen, slowly and deliberately returned fire, pouring shot after shot into the hulls of the anchored British warships. During the battle, a British cannonball cut the fort's flagstaff, and Moultrie's blue flag with its white crescent fell outside the walls. Sergeant William Jasper leaped over the ramparts under heavy fire, retrieved the colors, tied them to a makeshift staff, and planted them back on the fort — an act of bravery that became legendary. The British were repelled with 91 killed and 170 wounded, against American losses of just 12 killed and 25 wounded. It was the patriot cause's first major military victory. The South Carolina General Assembly renamed the fortification Fort Moultrie in honor of its commander, and the anniversary was celebrated locally beginning in 1777, initially known as Palmetto Day and later as Carolina Day.

The Siege and Fall: 1779–1780

Charleston was not attacked again until May 1779, when General Augustine Prevost led a force of some 2,500 soldiers north from Savannah. Prevost reached the city gates, and the civilian leadership, outnumbered and isolated, briefly contemplated offering the British a declaration of neutrality to take South Carolina out of the war. The approach of Continental reinforcements under General Benjamin Lincoln forced Prevost to withdraw toward Savannah, but the episode exposed Charleston's vulnerability.

The decisive blow came in the spring of 1780. On December 26, 1779, a massive British fleet set sail from New York for Charleston. The armada numbered over 100 ships, including 90 transports and numerous warships, carrying more than 13,500 British and Hessian soldiers and sailors. In February 1780, Clinton's forces landed approximately 30 miles south of Charleston and began their march overland. General Washington warned Lincoln of the impending attack but expressed regret that he could not offer military assistance because of the need to maintain Continental forces around New York City. When Lincoln arrived, many of the fortifications defending Charleston's harbor were in disrepair.

On April 1, 1780, British forces began digging siege lines across the neck of the Charleston peninsula. On April 8, the Royal Navy forced its way past Fort Moultrie, seizing control of Charleston Harbor. That same day, 750 Virginia Continentals under Brigadier General William Woodford arrived to reinforce the garrison. On April 14, a force under Lt. Colonel Banastre Tarleton smashed the American cavalry at Moncks Corner, cutting off Charleston from potential reinforcement. Clinton sent Lord Cornwallis over the Cooper River to block escape, and the British effectively enveloped the city. Washington had advised Lincoln to abandon Charleston to save his Continental troops if necessary, but the civilian leadership, led by Lieutenant Governor Christopher Gadsden, strongly opposed evacuation. The city's civilian leaders even threatened to destroy any boats used in an evacuation attempt.

On May 12, 1780, Lincoln surrendered. The losses were staggering: approximately 5,266 prisoners — encompassing twenty-three Continental regiments from four states, plus hundreds of Continental Navy personnel — along with over 300 cannons, nearly 6,000 muskets, and vast stores of ammunition and supplies. It was the largest surrender of American forces during the entire war. The surrender terms were harsh: Lincoln's army was refused the honors of war, and while senior officers awaited exchange in relatively comfortable quarters, the common soldiers and junior officers were confined in appalling conditions aboard prison ships moored in the Cooper River. Many of the 2,500 Continentals did not survive their imprisonment. Ironically, an accidental explosion in a powder magazine after the surrender — triggered when soldiers carelessly stacked captured muskets — killed more men than had died in the actual siege.

Occupation: 1780–1782

From May 1780 to December 1782 — a period of two years, seven months, and two days — Charleston endured British military occupation. The city was administered by a "Board of Police" created by the British military authorities and was effectively under martial law. Those who publicly pledged loyalty to the Crown enjoyed greater personal and commercial freedoms, while those who scorned the occupying power lived under constant surveillance. The British required citizens whose loyalties were suspect to subscribe to an oath of allegiance, and those deemed a more serious threat had their property confiscated or were exiled. Prominent patriots, including Declaration of Independence signer Thomas Heyward Jr., were captured and exiled to St. Augustine, Florida.

The British also struck at the symbols of rebellion. After capturing the city, General Henry Clinton ordered his troops to chop down Charleston's Liberty Tree — the venerable live oak under which the Declaration of Independence had been read — and burn the stump to prevent
