Fort Mifflin

Fort on the Delaware River below Philadelphia, Pennsylvania

About

Fort Mifflin, originally called Fort Island Battery and also known as Mud Island Fort, was commissioned in 1771 and sits on Mud Island (or Deep Water Island) on the Delaware River below Philadelphia, Pennsylvania near Philadelphia International Airport.

During the American Revolutionary War, the British Army bombarded and captured the fort as part of their conquest of Philadelphia in autumn 1777. In 1795, the fort was renamed for Thomas Mifflin, a Continental Army officer and the first post-independence Pennsylvania governor.
