First Troop Philadelphia City Cavalry (Images of America: Pennsylvania)

Organized on November 17, 1774, the First Troop Philadelphia City Cavalry is the oldest mounted unit in the United States Army and one of the oldest units in the National Guard. First City Troopers are adaptable and are just as comfortable patrolling the streets in combat boots as they are on horseback, dressed in period uniforms. For the soldiers of the First City Troop, past and present come together in traditions of service and ceremony that date from the earliest days of the United States. First City Troopers are also notable for their civilian accomplishments as community leaders, artisans, architects, and professionals whose lives and careers have left a mark on their city and nation.
