Barges inside Gregg at eleven at night
The Federals did not fire a shot in reply to the Sullivan’s Island and James Island batteries, which worked on Gregg, Wagner and the parties building between them. At eleven at night the commanding officer at Fort Johnson watched barges moving inside Battery Gregg — the Federals, like the Confederates, did their real work after dark.
