March 29, 1780 – Siege of Charleston was one of the major battles which took place towards the end of the American Revolutionary War, after the British began to shift their strategic focus towards the American Southern Colonies. After about six weeks of siege, Continental Army Major General Benjamin Lincoln surrendered forces numbering about 5,000 to the British. The British government instructed Sir Henry Clinton to head a combined military and naval expedition southward. He evacuated Newport, Rhode Island, on October 25, 1779, and left New York City in command of Hessian General Wilhelm von Knyphausen. In December, he sailed with 8,500 troops to join Colonel Mark Prevost at Savannah. Charles Cornwallis accompanied him, and later Lord Rawdon joined him with an additional force, raising the size of the expedition to around 14,000 troops and 90 ships. Marching upon Charleston via James Island, Clinton cut off the city from relief, and began a siege on April 1. Skirmishes at Monck’s Corner and Lenud’s Ferry in April and early May scattered troops on the outskirts of the siege area. Benjamin Lincoln held a council of war, and was advised by de Laumoy to surrender given the inadequate fortifications. Clinton compelled Lincoln to surrender on May 12. The loss of the city and its 5,000 troops was a serious blow to the American cause. It was the largest surrender of an American armed force until the 1862 surrender of Union forces at Harper’s Ferry during the Antietam Campaign. The last remaining Continental Army troops were driven from South Carolina consequent to the May 29 Battle of Waxhaws. General Clinton returned to New York City in June, leaving Cornwallis in command with instructions to also reduce North Carolina.
