Photo #: NH 61567 USS Essex (1861-1865) At a Mississippi River area port, circa 1862-65. The original caption identified location and date as Baton Rouge, Louisiana, in July 1862. However, the presence of a mortar boat (at right) indicates that either the date is later or the location is above Vicksburg if the photo was taken in 1862. The original photograph accompanied a claim filed by James A. Payne. U.S. Naval History and Heritage Command Photograph.
