The 1780 British siege of Charlestown, South Carolina, was a pivotal battle of the American Revolutionary War. The siege lasted from March 29 to May 12, 1780, and resulted in the surrender of the city to the British.
The British forces, commanded by General Sir Henry Clinton, had sailed south from New York City and landed thirty miles south of Charlestown. After capturing James Island, the British then set their sights on Charlestown, which was a major American stronghold.
The American forces, led by General Benjamin Lincoln, were outnumbered and outgunned. They had hoped to hold out until reinforcements arrived, but the British siege was too effective. The British bombarded the city from land and sea, causing extensive damage to the fortifications and forcing the Americans to retreat to a smaller perimeter.
After several weeks of fighting, the British breached the American outer defenses and launched a final assault. General Lincoln surrendered his army on May 12, 1780, and Charlestown became a British stronghold for the remainder of the war.
The loss of Charlestown was a significant blow to the American cause, as it was one of their largest and most strategically important cities. The British victory gave them control of the southern ports and allowed them to launch further attacks on the American forces.
