Fort Mifflin (Revolutionary War siege and hauntings)

Fort Mifflin, located on the Delaware River, was the site of a protracted British siege and bombardment in November 1777 that delayed British supply lines during the Philadelphia campaign. The fort's surviving earthworks and restored structures are open for public tours and programs interpreting its Revolutionary War history. Over the 20th and 21st centuries the site has accumulated local ghost stories and reports of supernatural occurrences, which are presented as folklore alongside documented military history.
