Charles Armand Tuffin, Marquis de la Rouërie (13 April 1751 - 30 January 1793), also known in the United States as "Colonel Armand," was a Breton cavalry officer who served under the American flag in the American War of Independence. He was promoted to brigadier general after the Battle of Yorktown. He is also known as a founder and early leader of the Breton Association (the "Chouannerie") during the French Revolution. La Rouërie is less-remembered than Lafayette and others in writings of French participation in the Revolutionary war.
