Battle of Monck's Corner

On April 14, 1780, fighting broke out at Monck's Corner, a location just beyond Charleston, South Carolina, at a time when Clinton's British troops had the city under siege. Tarleton's British Legion caught a Patriot detachment posted there off guard and pushed the defenders back. With this route sealed, Lincoln's trapped army lost one of its remaining paths of retreat. Beyond the Legion itself, the attacking force drew in the 33rd Foot and 64th Foot under Webster's command, along with Ferguson's American Volunteers.

Background

Most of the British forces engaged at Monck's Corner consisted of Loyalist units drawn from South Carolina itself, though they were joined by a detachment of the 17th Light Dragoons led by Captain William Henry Talbotwith. Lieutenant Colonel Banastre Tarleton commanded a separate outfit called the British Legion. British operations in the region began on 1 April 1780, when General Sir Henry Clinton reached the outskirts of Charleston, South Carolina, and set siege preparations in motion, part of a broader scheme to bring the Carolinas under British control. Charleston's defense fell to Continental Army forces commanded by General Benjamin Lincoln. Reinforcements kept streaming into the city even as British siege lines went up around portions of it; on 8 April, William Woodford brought 750 Virginia Continentals into Charleston to bolster its garrison.

Word reached Clinton of a supply train approaching the city, which turned out to be the baggage belonging to Woodford's own unit, and he moved to sever this line of supply. To accomplish this, he dispatched Lieutenant Colonel James Webster with 1,400 men inland roughly 30 miles (48 km) toward Biggin's Bridge on the Cooper River, where the train might be intercepted.

Securing this operation meant confronting General Isaac Huger, whose 500-man detachment Lincoln had positioned at Monck's Corner to guard the approach. Huger's command included cavalry under Lt. Col. William Washington along with a portion of Pulaski's Legion led by Chevalier Pierre-Francois Vernier. Tarleton gained a critical advantage on the night of 13 April when he intercepted correspondence Huger had written to Lincoln, revealing exactly how Huger's troops were arranged. The advance toward Monck's Corner then proceeded quietly, without further incident.

Battle

At three in the morning on April 14, British forces launched their assault, and the encounter swiftly collapsed into a chaotic flight for the Americans.

Tarleton later described the scene, noting that the Americans were caught entirely off guard, with General Huger, Colonels Washington and Jamieson, along with numerous officers and men, escaping on foot into the surrounding swamps.

The toll on the American side amounted to 14 dead, 19 injured and 64 taken prisoner. Yet the greatest loss lay elsewhere: the seizure of horses belonging to American officers and cavalry proved the most valuable gain of the engagement.

Aftermath

This decisive southern triumph established Tarleton as a commander known for rapid, unexpected assaults. Survivors from Huger's scattered command struggled toward the north and east, eventually reassembling under Colonel Anthony Walton White. Tarleton caught up with them once more, dispersing this reformed unit at Lenud's Ferry on 6 May. Charleston fell soon after, as Lincoln had no choice but to surrender the city along with over 5,000 Continental Army soldiers on 12 May. No defeat in the entire war inflicted greater damage on American forces. Not until the Civil War, at the Battle of Harper's Ferry, would the United States Army again endure a setback of comparable magnitude.
