The First Troop Philadelphia City Cavalry, or "First City Troop", was organized in 1774 as the Light Horse of the City of Philadelphia, often referred to as the Philadelphia Light Horse, one of the first patriotic military organizations established in the American Revolution. Abraham Markoe was the founder and the first Captain of the Philadelphia Light Horse, known today as the First Troop Philadelphia City Cavalry. During the Revolution, the troop fought in the battles of Trenton, Princeton, Brandywine, and Germantown. It often served as George Washington's personal bodyguard. The unit also saved James Wilson at the "Battle of Fort Wilson" riot. It is one of the oldest military units in the United States still in active service and is among the most decorated units in the U.S. Army.
