A one time aide-de-camp to the uncle of Charles, Lord Cornwallis, Horatio Gates participated in Maj. Gen. Edward Braddock's campaign against Fort Duquesne and received a wound at the Battle of the Monogahela. Shortly after the Battles of Lexington and Concord, Gates offered his services to George Washington, who recommended him to the Continental Congress. Gates eventually received a commission as Brigadier General in the Continental Army. In May 1776, Gates received a promotion to Major General and the following March command of the Northern Department. Later that fall, Gates defeated Lt. Gen. John Burgoyne at the Battle of Saratoga, which effectively brought France into the war as an ally of the United States. Gates then headed the Board of War after the fall of Charleston in May, 1780 received command of the Southern Department. Three months later, Cornwallis soundly defeated Gates's army at Camden, South Carolina. Gates's reputation never recovered following the battle and never again held an independent command.
