Spirits of 1776

Fort Mifflin, Mud Island, Philadelphia ★ FREE PIN

📍 6400 Hog Island Road, Philadelphia, PA 19153

Fort Mifflin sits on a low island of mud and marsh where the Schuylkill meets the Delaware, close enough to the end of the Philadelphia airport runway that jets pass directly over the parade ground. In the autumn of 1777 that unglamorous patch of river was the most important ground in North America. Howe had taken Philadelphia, but an occupied city is useless without supply, and supply meant getting the Royal Navy up the Delaware. Fort Mifflin and Fort Mercer across the river were the cork in that bottle.

Between 400 and 450 Americans held the fort against roughly 2,000 British troops and a naval squadron. On November 10, 1777 the British opened what is still described as the heaviest bombardment of the entire Revolutionary War, and they kept it up for days. When the garrison finally evacuated on the night of November 15, about 250 of its defenders had been killed or wounded. More than half. What those men bought with that week was time, and Washington used it to reposition for White Marsh and then march the army into winter quarters at Valley Forge. The Revolution continued because Fort Mifflin did not fall on schedule.

The fort's second life was arguably grimmer. From 1863 to 1865 the Union held Confederate prisoners of war in Casemate No. 1 and political prisoners in the smaller casemates, stone rooms built into the walls with no real light and no real air. The fort was never fully decommissioned until 1954, which is part of why so much of it survives intact.

The hauntings people report here are unusually specific, and they have names. The Screaming Woman is the famous one, generally identified as Elizabeth Pratt, said to be a sergeant's wife who lost her children to yellow fever and then died of it herself. Philadelphia police have reportedly been dispatched to the fort over screams coming from the officers' quarters, and found the building empty. The Faceless Man sits hunched in the dark of Casemate No. 5, apparently sewing, and raises his head to show nothing at all; he is often linked to William H. Howe, a Union private hanged at the fort with a hood over his head. The Lamplighter, sometimes called Joseph Adkins, walks the soldiers' barracks with a long pole and a candle, lighting lamps that were removed two centuries ago.

Expedition X S12 E05, "Spirits of 1776" (2026)

The season 12 finale is built around America's 250th anniversary, and Fort Mifflin is where the episode establishes what Revolutionary War haunting actually means. Phil Torres and Heather Amaro are joined here by Jack Osbourne, which is a nice piece of continuity, because Osbourne has been inside these walls before (see below). The fort is the rare Revolutionary site where the reported activity is not vague battlefield residue but named, repeat, documented figures, which makes it a sensible control point before the team moves out to the open ground at Brandywine.

Portals to Hell S3 E5, "Fort Mifflin" (2022)

Katrina Weidman brought Jack Osbourne to Fort Mifflin in the third season of Portals to Hell, an episode that aired on Travel Channel on May 7, 2022. Weidman had described the fort as one of her favorite locations in the country, and the pair worked the casemates and the officers' quarters looking for the figures above. Four years later Osbourne is back on the same ground with a different show and a different team, which is the sort of thing that only happens at locations with a genuinely long investigation record.

Ghost Hunters S4 E1, "Fort Mifflin" (2008)

TAPS opened their entire fourth season here. Jason Hawes, Grant Wilson and Steve Gonsalves were walked through the fort by caretaker Wayne Irby, who laid out the reported apparitions before the lights went out. The investigation focused heavily on Elizabeth and the officers' quarters, and the moment that made the episode was an EVP capture during which Hawes believed he heard a young girl's voice asking for her mother. Whatever you make of it, it is the single piece of audio that put Fort Mifflin on the national paranormal map.

Brandywine Battlefield, Chadds Ford ★ FREE PIN

📍 Brandywine Battlefield Park, 1491 Baltimore Pike, Chadds Ford, PA 19317

September 11, 1777 was the longest single day of combat in the Revolutionary War, roughly eleven hours of it, and the largest land battle of the whole conflict measured by troops engaged on one day. Washington set up along the Brandywine expecting Howe to come straight at him across Chadds Ford. Howe did not. He left a force to make noise at the ford, took the bulk of his army on a wide flanking march north, crossed at Trimble's and Jefferis's fords, and came down on the American right from a direction Washington's scouts had assured him was clear.

By the time the Continentals understood what had happened, British and Hessian troops were already forming up on Osborne's Hill. The American line reassembled in a hurry on Birmingham Hill and was driven off it. The army got away, mostly intact, toward Chester and then Philadelphia, but the city fell on September 26 and Congress fled to York. Estimates of the dead, wounded and captured run to roughly 1,300 Americans and around 600 British.

What makes Brandywine unusual as a paranormal location is how much of it survives as it was. This is not a battlefield under a shopping center. Brandywine Battlefield Park preserves Washington's headquarters at the Benjamin Ring house and Lafayette's quarters at the Gideon Gilpin house, and beyond the park boundary the fields, fords, farm lanes and stone houses of Chadds Ford and Birmingham Township still read as 18th century ground. The reports that come off it are the kind you would expect: column sounds and drumbeats with nothing in sight, musket fire out of empty fields, figures in period dress on the tree lines at dusk, and a great deal of activity around the old houses that were pressed into service as hospitals.

Expedition X S12 E05, "Spirits of 1776" (2026)

Discovery's own framing for the finale puts the team on "historic battlefields in Pennsylvania" chasing Revolutionary War ghosts during the country's 250th birthday, and the Brandywine River ground is the heart of it. The team works the battlefield with Jack Osbourne, which for a location this open is a real test: a battlefield has no walls to bounce a voice off and no caretaker's stories to anchor a night, only the terrain and the record. Brandywine has an exceptionally good record. Every feature of the 1777 map can still be stood on.

Sandy Hollow, Birmingham Township ★ FREE PIN

📍 Sandy Hollow Heritage Park, Birmingham Road, Birmingham Township, Chester County, PA

When the American line broke on Birmingham Hill, what was left of it fell back a few hundred yards to a shallow bowl of high ground called Sandy Hollow and stopped there. This was the last stand of the day, made in fading light, and it is usually described as the sunset stand. It was not a victory and it was not meant to be one. Holding that hollow for the last hour of daylight is what allowed the rest of Washington's army to get off the field in something other than a rout, which is the only reason there was still a Continental Army on September 12.

It cost accordingly. Anthony Wayne's and Adam Stephen's men took heavy casualties in and around the hollow, and it was somewhere on this ground that the Marquis de Lafayette, twenty years old and in his first battle, was shot through the leg while trying to rally troops. He kept his feet long enough to keep the retreat orderly, which is the anecdote that made him famous in America.

Sandy Hollow Heritage Park preserves about 42 acres of that ground, kept deliberately open and largely as it looked in 1777. It is quiet, it is beautiful, and it is the specific patch of Pennsylvania where the most men died in the shortest time on the worst day of the campaign. Visitors report cold spots that do not track with the wind, voices and orders just under the threshold of understanding, and the flat certainty of being watched from the tree line as the light goes. Expedition X worked it as part of the same night as the wider Brandywine investigation, and of the three sites in this report it is the one with the least infrastructure and the most concentrated history.

Birmingham Friends Meetinghouse & Burial Ground

📍 Birmingham Road at Meetinghouse Road, Birmingham Township, Chester County, PA

The Quakers who built this plain stone meeting house were pacifists, and the battle came through their front yard anyway. The meetinghouse stands immediately beside Birmingham Hill, which put it in the middle of the fighting on the afternoon of September 11. It was taken over as a field hospital, first by the Continentals and then, within hours, by the British as they swept the Americans off the hill. The wounded of both armies were carried into the same room and laid on the same floor.

The men who did not survive that room were buried together in the burial ground outside, British and American in a common grave, because nobody was in a position to sort them. There is a marker there now. It is one of the quietest and bleakest spots in Chester County, and it explains why so much of the reported activity in this township clusters within a half mile of a building where no one ever fired a shot on purpose.

The meetinghouse is still an active Friends meeting, so it is not an investigation site in the way Fort Mifflin is. It is the context. If you visit Sandy Hollow or Birmingham Hill, stop here first and read the marker, and the rest of the ground will make a great deal more sense.
