The story
Fort Delaware commands Pea Patch Island in the Delaware River off Delaware City, a massive granite-and-brick pentagon completed in 1859 that became one of the Union's largest prisoner-of-war depots: at its 1863 peak after Gettysburg some 12,000 Confederate prisoners crowded its barracks, and across the war roughly 2,500 died, mostly of disease, many buried across the river at Finn's Point — a documented toll that any account must carry soberly. Preserved as Fort Delaware State Park, the fortress is reached by seasonal ferry, interpreted by costumed living history, and famous in the paranormal field since early national television investigations: staff, re-enactors and visitors describe voices and chains in the dungeons and tunnels, figures on the ramparts and in the officers' quarters, touches, kitchen sounds, and cries from the prison bastions. These reports should be presented as park-era telling layered on real suffering, with the prisoners' dead honoured first. Ferry schedules, tours and paranormal-event details should be confirmed from the state park's official pages before publishing.
