The summer of 1776 was a season poised on the edge of a knife. In Philadelphia, the Second Continental Congress debated the dangerous, irreversible words of a formal declaration of independence. Meanwhile, hundreds of miles to the south, the war was already arriving in full force on the shores of South Carolina.
On June 28, 1776, a massive British fleet anchored off the bar of Charles Town Harbor. It was the opening scene of a battle that would determine the fate of the American South—and one that would be decided by the most unexpected of defensive shields: the green, spongy wood of the native palmetto tree.
The Gateway to the South
Following their evacuation from Boston in March 1776, British military leaders scrambled to find a new opening to suppress the colonial rebellion. Frustrated in North Carolina, where local Patriot forces had successfully disrupted Loyalist gathering plans, the Crown turned its gaze further south.
The prize they chose was Charles Town (modern-day Charleston). As one of the most prosperous, influential coastal cities in the lower South, Charles Town was a vital economic artery connecting the colonies to the global Atlantic trade through rice and indigo. To British planners, the city’s harbor was the ultimate strategic prize: capture it, and they would secure a permanent foothold to roll up the southern rebellion.
Standing directly in the path of the Royal Navy was a small, unfinished fortification on the southern tip of Sullivan’s Island.
"A Slaughter Pen": The Battle of Wills
To professional military minds, the situation seemed hopeless. Major General Charles Lee, the eccentric former British officer appointed by Congress to command the Continental Army’s Southern Department, was appalled when he inspected the Sullivan’s Island defenses. The fort was only half-completed, featuring a double-walled palmetto log frame sixteen feet wide, filled with sand, and open at the rear.
General Lee famously declared the fort a "slaughter pen," predicting that the heavy guns of the Royal Navy would easily reduce the soft wooden structure to kindling and annihilate the defenders. Lee urged South Carolina’s President, John Rutledge, to abandon the island entirely and pull the forces back to the mainland.
But Rutledge and the local commander, Colonel William Moultrie of the 2nd South Carolina Regiment, refused. Rutledge insisted that the harbor must be defended, and Lee reluctantly bowed to local pressure, leaving Moultrie’s garrison of fewer than 450 men to face the coming storm. Lee’s parting order to Moultrie was grim: if his severely limited supply of gunpowder and iron shot ran out, he was to spike his cannons and retreat immediately.
The Miracle of the Palmetto
At approximately 10:00 AM on the morning of June 28, 1776, Sir Peter Parker’s fleet of nine heavily armed British warships, boasting nearly 300 cannons, sailed into position and unleashed a thunderous broadside.
But as the heavy iron 32-pounder cannonballs slammed into the fort’s walls, the laws of physics took a surprising turn. Standard European fortifications of the era were built of stone or hard oak, which would shatter and send deadly, jagged splinters flying through the air upon impact. The walls of Fort Sullivan, however, were built of green, freshly cut palmetto logs.
Instead of shattering, the soft, fibrous, and spongy palmetto wood bent under the impact. Backed by sixteen feet of packed sand, the walls simply swallowed the British cannonballs whole, absorbing their kinetic energy harmlessly. According to Colonel Moultrie, some balls even bounced off, while others buried themselves deep in the sand without doing any structural damage.
Cool Heads and Scarce Powder
Inside the fort, Moultrie’s men faced a different crisis: they had only a fraction of the gunpowder needed for a prolonged battle. While the British warships poured thousands of rounds into the island, Moultrie ordered his men to conserve every ounce of powder.
They did not fire in rapid, frantic bursts. Instead, they acted with legendary composure, firing in slow, deliberate volleys; just four cannons at a time. The Patriots took careful, painstaking aim, focusing their fire on the massive British flagship, HMS Bristol, and the HMS Experiment. A British observer later wrote in astonishment that the Patriots' fire was "slow, but decisive indeed... exceedingly well directed." The precise colonial cannon fire raked the decks of the British ships, inflicting heavy casualties and even wounding Admiral Parker himself.
The Trap at Breach Inlet
Meanwhile, the British plan for a dual land assault was falling apart at the northern end of Sullivan's Island. Major General Sir Henry Clinton had landed 2,200 British infantrymen on neighboring Long Island (now Isle of Palms), intending to wade across the narrow channel known as Breach Inlet to attack the fort’s exposed rear.
The British had been assured by scouts that the inlet was shallow enough to cross on foot at low tide. However, when Clinton’s troops attempted the crossing, they discovered to their horror that the water was over seven feet deep—making wading impossible.
As the British troops sat stranded in their flat-bottomed boats, Colonel William Thomson and his force of 800 defenders, including thirty allied Catawba warriors, held the opposite bank with two cannons. Thomson's men unleashed a withering barrage of grape shot, turning the inlet into a defensive wall that prevented any amphibious landing.
A Shield for the South
By 9:30 PM, after more than nine hours of continuous combat, the British fleet slipped their anchor lines and quietly retreated into the Atlantic. They had fired over 7,000 rounds and expended twelve tons of powder, yet the unfinished palmetto-log fort stood virtually undamaged.
The Battle of Sullivan's Island was the first decisive American naval victory of the Revolutionary War. It occurred just one week before the Declaration of Independence was formally adopted in Philadelphia on July 4, 1776. The news of Moultrie's improbable victory swept through the colonies, providing a massive surge of momentum and confidence to the Patriots at a crucial historical moment.
By successfully repelling the invasion, the defenders of Sullivan’s Island protected Charles Town and kept the British from securing a stronghold in South Carolina for another four years. In honor of his brilliant leadership, the South Carolina General Assembly renamed the stronghold Fort Moultrie. In 1861, the resilient palmetto was honored with a permanent place on South Carolina’s state flag.
Steep a Cup of History
The story of Sullivan's Island is one of unlikely materials and unmatched resolve, proving that the softest elements can sometimes withstand the hardest blows.
Our Charles Towne Tea pays tribute to the city and harbor at the center of that story. The limited-edition tin contains East Indian tea, a malty black tea connected to Charleston’s history of resistance to taxed imports. Together, the tea and tin recall a place where opposition took many forms, from protests along the waterfront to the defense of the harbor at Sullivan’s Island.
