Fort Warren

During the Civil War, Fort Warren trained Massachusetts regiments and held Confederate prisoners, both soldiers and civilian officials swept up in the conflict's early seizures. Its most famous inmate was Confederate Vice President Alexander H. Stephens, confined there from May to October 1865 after the war ended. The fort stayed in service through both World Wars and was decommissioned in 1951.

Georges Island itself nearly had a stranger second life: at one point it was slated to become a nuclear waste disposal site. Preservation — credited largely to historian Edward Rowe Snow — made it instead the cornerstone of the Boston Harbor Islands National Recreation Area, a 28-acre island reached by summer ferry, its casemates and tunnels open to anyone willing to walk into the dark.

The story as the rangers tell it: in 1862 a young Confederate officer — Lieutenant Andrew Lanier, or Samuel, the name drifts between versions — was captured and imprisoned at Fort Warren. Word reached his new bride Melanie, who was rowed across from Hull on a stormy night, hair cut short, wearing a soldier's uniform, an old pistol in her pocket. She hid in the casemates and joined the prisoners digging an escape tunnel.

A guard heard the pickaxe strike granite. Colonel Dimmick caught the couple; Melanie fired, the old pistol misfired, and in the smoke her own husband lay dead. She was hanged as a Confederate accomplice — in a black robe the prisoners made for her, since the fort had no woman's clothes — and became the Lady in Black, who is said to walk the archways still.

The archive keeps the counter-file next to the legend. The Roanoke Island campaign that supposedly produced Lanier's capture ran in February 1862; no record shows a Lanier in the fort's prisoner rolls, no woman was ever tried or executed at Fort Warren, and the tale's printed trail begins decades after the war — spread widest by Snow himself, who admitted in The Romance of Boston Bay that he could not swear to its truth, only that many people now believed it.

Witness reports, filed anyway: a soldier on guard duty felt hands close on his neck and turned to face a woman in black; a sergeant heard a woman's voice warn "Don't come in here" from a casemate where only men were posted. Rangers still tell the tale daily and some, the record notes, claim to have seen her.

Fort Warren closes its file neatly: a fort that never fired a shot, haunted by a woman who never lived there, preserved by a storyteller who never pretended she did. The granite is documented, the hanging is legend, and the hands on the neck are reported experience. All three columns stay open at the Dark Arch, 12:30 daily.
