Philadelphia Light Horse Flag

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.

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.
