The Gun that Sunk the 'Alabama'.... Halftone reproduction of a photograph of Kearsarge's after XI-inch Dahlgren pivot gun, with ship's officers and the quarter deck beyond, circa the 1870s. This gun has an iron pivot mounting, of a type adopted after the Civil War, and may or may not be the same weapon that was on board the ship at the time of her battle with CSS Alabama in June 1864. Copied from Francis T. Miller's The Photographic History of the Civil War, Volume VI: The Navies, page 303. U.S. Naval History and Heritage Command Photograph.
