National Historical Landmark-Fort Mifflin

In October and November 1777, Fort Mifflin was the scene of a spirited defense by the Americans against a British fleet intent on opening the Delaware River supply line into newly captured Philadelphia.

Although the British captured and destroyed the Fort, this battle, along with those at Brandywine and Germantown, cost the British time and men and frustrated their efforts to disrupt the rebel government and its army.

After the Revolution, the Fort was rebuilt according to the designs of Pierre L'Enfant. Several of the extant buildings inside the fort date back to this time; others were erected subsequently throughout the 19th century.
