The Battle of Guilford Court House was on March 15, 1781, during the American Revolutionary War, at a site that is now in Greensboro, the seat of Guilford County, North Carolina. A 2,100-man British force under the command of Lieutenant General Charles Cornwallis defeated Major General Nathanael Greene's 4,500 Americans.

The battle was "the largest and most hotly contested action"in the American Revolution's southern theater. Before the battle, the British had great success in conquering much of Georgia and South Carolinawith the aid of strong Loyalist factions and thought that North Carolinamight be within their grasp. In fact, the British were in the process of heavy recruitment in North Carolina when this battle put an end to their recruiting drive. In the wake of the battle, Greene moved into South Carolina, while Cornwallis chose to march into Virginia and attempt to link with roughly 3,500 men under British Major General Phillips and American turncoat Benedict Arnold.

This battle marked a turning point in the Revolutionary War in the South. Although General Cornwallis, the British commander, held the field at the end of the battle, his losses were so severe that he decided to withdraw to the Carolina coastline, where he could receive reinforcements from the British Royal Navy at the port in Wilmington and his battered army could be protected by the British naval power. His decision ultimately led to his leading his ravaged army north into Virginia leading eventually to his defeat and surrender later in October 1781 at Yorktown.

The battle belongs to a wider southern campaign. After difficult fighting and marches through the Carolinas, Greene chose ground where his mixed Continental and militia force could confront the pursuing British. The American lines did not all stand in the same way, and the action moved through woods and clearings. British discipline carried the field, but repeated attacks and casualties reduced Cornwallis’s ability to exploit the tactical victory.

Greene then turned south to contest British outposts, while Cornwallis marched toward Wilmington and subsequently Virginia. This operational split changed the campaign without making Guilford Court House a simple American battlefield victory. The park now preserves and interprets traces of the fight within modern Greensboro. Visitors should read the monuments critically: some reflect later memorial choices as well as the events of 1781. The losses on both sides, Greene’s subsequent manoeuvres and Cornwallis’s decision to move north explain why a British tactical success could still weaken the wider British campaign.
