Is Cowell’s Battery haunted?
No claims are filed here — the record keeps this place for its documented history, not for a haunting on file.
The record — long form
Cowell's Battery occupies the southernmost peak of Hassel Island, the high ground that — with Fort Willoughby across the way — closed the entrance to Charlotte Amalie harbor. The British raised it in 1801 during their first occupation of the Danish West Indies, arming it with two 24-pound naval cannon, five and a half thousand pounds of iron apiece, hauled up the hill by hand; the Danish lieutenant Peter Oxholm had marked the site as a defensive point as early as 1780.
The battery takes its name from Colonel John Clayton Cowell of the Royal Regiment of Foot, the British governor of St. Thomas during the 1801–02 occupation, who died on the island and is buried on it somewhere — the file's research notes decline the more specific grave claims the tour brochures repeat.
From cannon to signal mast
In the later nineteenth century the battery became the harbor's signal station: a tall mast flew balls and squares telling the town what shipping was arriving or passing, flanked by signal cannons to draw attention, with quarters for the signaling crew that eventually — in the 1950s — acquired flush toilets.
The ruins sit inside the Hassel Island Historic District on the National Register, in a national-park island that keeps its military fabric legible. The dossier files it as military ruins with no haunting claim — documented fortifications from a brief imperial war, still watching the harbor mouth.
