Siege of Charleston in the American Revolution

Siege of Charleston in the American Revolution The Siege of Charleston took place from March 29 to May 12, 1780, during the American Revolution (1775-1783) and came about after a change in British strategy. Shifting their focus to the southern colonies, the British first captured Savannah, GA in 1778 before mounting a major expedition against Charleston, SC in 1780. Landing,  Lieutenant General Sir Henry Clinton conducted a brief campaign that drove American forces under Major General Benjamin Lincoln back into the Charleston. Conducting a siege of the city, Clinton compelled Lincoln to surrender. The defeat resulted in one of the largest single surrenders of American troops and created a strategic crisis in the South for the Continental Congress. Background In 1779, Lieutenant General Sir Henry Clinton began making plans for an attack on the Southern colonies. This was largely encouraged by a belief that Loyalist support in the region was strong and would facilitate its recapture. Clinton had attempted to capture Charleston, SC in June 1776, however the mission failed when Admiral Sir Peter Parkers naval forces were repulsed by fire from Colonel William Moultries men at Fort Sullivan (later Fort Moultrie). The first move of the new British campaign was the capture of Savannah, GA. Arriving with a force of 3,500 men, Lieutenant Colonel Archibald Campbell took the city without a fight on December 29, 1778. French and American forces under Major General Benjamin Lincoln laid siege to the city on September 16, 1779. Assaulting the British works a month later, Lincolns men were repulsed and the siege failed. On December 26, 1779, Clinton left 15,000 men under General Wilhelm von Knyphausen in New York to hold General George Washingtons army at bay and sailed south with 14 warships and 90 transports for another attempt on Charleston. Overseen by Vice Admiral Mariot Arbuthnot, the fleet carried an expeditionary force of around 8,500 men.

Regrouping off Tybee Roads, Clinton landed a small diversionary force in Georgia before sailing north with the bulk of the fleet to Edisto Inlet approximately 30 miles south of Charleston. This pause also saw Lieutenant Colonel Banastre Tarleton and Major Patrick Ferguson go ashore to secure new mounts for Clintons cavalry as many of the horses that had been loaded in New York had suffered injuries at sea. Unwilling to attempt forcing the harbor as in 1776, he ordered his army to begin landing on Simmons Island on February 11 and planned to approach the city by an overland route. Three days later British forces advanced on Stono Ferry but withdrew upon spotting American troops. Returning the next day, they found the ferry abandoned. Fortifying the area, they pressed on towards Charleston and crossed to James Island. In late February, Clintons men skirmished with American forces led by Chevalier Pierre-Franà §ois Vernier and Lieutenant Colonel Francis Marion. Through the rest of the month and into early March, the British wrested control of James Island and captured Fort Johnson which guarded the southern approaches to Charleston harbor. With control of the southern side of the harbor secured, on March 10, Clintons second in command, Major General Lord Charles Cornwallis, crossed to the mainland with British forces via Wappoo Cut (Map). American Preparations Advancing up the Ashley River, the British secured a series of plantations, such as Middleton Place and Drayton Hall, as American troops watched from the north bank. While Clintons army moved along the river, Lincoln worked to prepare Charleston to withstand a siege. He was aided in this by Governor John Rutledge who ordered 600 slaves to construct new fortifications across the neck between the Ashley and Cooper Rivers. This was fronted by a defensive canal. Only possessing 1,100 Continentals and 2,500 militia, Lincoln lacked the numbers to face Clinton in the field. Supporting the army were four Continental Navy ships under Commodore Abraham Whipple as well as four South Carolina Navy vessels and two French ships. Not believing he could defeat the Royal Navy in the harbor, Whipple first withdrew his squadron behind a log boom which protected the entrance to the Cooper River before later transferring their guns to the land defenses and scuttling his ships. Though Lincoln questioned these actions, Whipples decisions were backed by a naval board. In addition, the American commander would be reinforced on April 7 by the arrival of Brigadier General William Woodfords 750 Virginia Continentals which raised his total strength to 5,500. The arrival of these men was offset by British reinforcements under Lord Rawdon which increased Clintons army to between 10,000-14,000. The City Invested Having been reinforced, Clinton crossed the Ashley under the cover of fog on March 29. Advancing on the Charleston defenses, the British began constructing siege lines on April 2. Two days later, the British constructed redoubts to protect the flanks of their siege line while also working to pull a small warship across the neck to the Cooper River. On April 8, the British fleet ran past the guns of Fort Moultrie and entered the harbor. Despite these setbacks, Lincoln retained contact with the outside via the north shore of the Cooper River (Map). With the situation rapidly decaying, Rutledge escaped the city on April 13. Moving to completely isolate the city, Clinton ordered Tarleton to take a force to sweep away Brigadier General Isaac Hugers small command at Moncks Corner to the north. Attacking on at 3:00 AM on April 14, Tarleton surprised and routed the Americans. After the fighting, Vernier was killed by Tarletons men despite asking for quarter. It was the first of several brutal actions taken by Tarletons men during the campaign. With the loss of this crossroads, Clinton secured the north bank of the Cooper River when Tarleton joined with Lieutenant Colonel James Websters command. This combined force advanced down the river to within six miles of the city and cut off Lincolns line of retreat. Understanding the severity of the situation, Lincoln called a council of war. Though advised to continue defending the city, he instead elected to parley with Clinton on April 21. In the meeting, Lincoln offered to evacuate the city if his men were permitted to depart. With the enemy trapped, Clinton immediately refused this request. Tightening the Noose Following this meeting, a massive artillery exchange ensued. On April 24, American forces sortied against the British siege lines but to little effect. Five days later, the British began operations against the dam that held the water in the defensive canal. Heavy fighting began as the Americans sought to protect the dam. Despite their best efforts, it was nearly drained by May 6 opening the way for a British assault. Lincolns situation further worsened when Fort Moultrie fell to British forces under Colonel Robert Arbuthnot. On May 8, Clinton demanded that the Americans unconditionally surrender. Refusing, Lincoln again attempted to negotiate for an evacuation. Again denying this request, Clinton began a heavy bombardment the following day. Continuing into the night, the British pounded the American lines. This, coupled with the use of hot shot a few days later, which set several buildings on fire, broke the spirit of the citys civic leaders who began pressing Lincoln to surrender. Seeing no other option, Lincoln contacted Clinton on May 11 and marched out of the city to surrender the following day.   Aftermath The defeat at Charleston was a disaster for American forces in the South and saw the elimination of the Continental Army in the region. In the fighting, Lincoln lost 92 killed and 148 wounded, and 5,266 captured. The surrender at Charleston ranks as the US Armys third largest surrender behind the Fall of Bataan (1942) and Battle of Harpers Ferry (1862). British casualties before Charleston numbered 76 killed and 182 wounded. Departing Charleston for New York in June, Clinton turned over command at Charleston to Cornwallis who quickly began establishing outposts across the interior. In the wake of the citys loss, Tarleton inflicted another defeat on the Americans at Waxhaws on May 29. Scrambling to recover, Congress dispatched the victor of Saratoga, Major General Horatio Gates, south with fresh troops. Rashly advancing, he was routed by Cornwallis at Camden in August. The American situation in the southern colonies did not begin stabilize until the arrival of Major General Nathanael Greene that fall. Under Greene, American forces inflicted heavy losses on Cornwallis at Guilford Court House in March 1781 and worked to regain the interior from the British.
