Brigadier General Francis Marion (c. 1732 – February 27, 1795), also known as the "Swamp Fox", was an American military officer, planter, and politician who served during the French and Indian War and the Revolutionary War. During the American Revolution, Marion supported the Patriot cause and enlisted in the Continental Army, fighting against British forces in the southern theater of the American Revolutionary War from 1780 to 1781. Though he never commanded a field army or served as a commander in a major engagement, Marion's use of irregular warfare against the British has led him to be considered one of the fathers of guerrilla and maneuver warfare, and his tactics form a part of the modern-day military doctrine of the U.S. Army's 75th Ranger Regiment.
