I'm looking for information on three forts on the east coast of the US, and any similar coastal battery emplacements with at least 4x16" cannons. I found these while leafing through a friend's book called Fortress America, and would like to confirm what I found. I am particularly interested in Fort Story and Camp Hero. Ft. Story (Chesapeake Bay) 4x16", 4x16" howitzers, 4x6", 4x90mm Ft. Green (Narragansett Bay) 2x16", 2x6", additional 2x16" planned, but not completed Camp Hero (HD of Long Island Sound) 4x16", 2x6"
