Description: Originally constructed by the British in 1771, Fort Mifflin was in American hands by the dawn of the Revolution. Site of the greatest bombardment of the Revolutionary War, the heroic defense of “Mud Island Fort” was instrumental in delaying the British re-supply of their occupying army in Philadelphia in November 1777. Ultimately overcome by the British bombardment, the garrison evacuated but left the flag flying. Fort Mifflin never surrendered.  Reconstructed beginning in the late 18th century, the Fort was garrisoned for the War of 1812, served as a federal prison during the Civil War and as a munitions depot and home front defense during World War I and World War II. It was decommissioned in 1954 and named a National Historic Landmark in 1970.
