Fort Delaware is on Pea Patch Island, in the middle of the river between Delaware and New Jersey. It was built as a river defense fort, but never used as such and instead served as a prison from 1861-1864 for Confederate soldiers. Many rebels captured during the battle of Gettysburg were incarcerated here, including General Pettigrew, after his defeat at Pickett's Charge. All told about 20,000 people stayed on the island, and over 2,000 of the prisoners died, mostly of disease rather than failed escapes. (These were light compared to the death toll at Andersonville).
Most of what I do at the fort is give equipment and weapons talks in the ordnance supply room when I'm not acting as a prison guard.
Sorry, but no pictures. All the interpreters do first-person impressions of 1864 and we have to stay in character, so only the public has the photo opportunity. This weekend will be a POW event at the fort, with more reenactors in attendance to act as prisoners. The event has been well advertized so hopefully it will draw some crowds.
I don't know when the next battle reenactment I can attend will be. Maybe not until next season.
