US Army 10-Inch Rodmans at Fort Moultrie
US Army 10-Inch Rodmans Number 156 and 182 are displayed on “Cannon Row” at Fort Moultrie
US Army 10-Inch Rodmans Number 156 and 182 which are displayed at Fort Moultrie on Sullivans Island, South Carolina were both manufactured at Fort Pitt Foundry in 1863. As manufactured they weighed 14,965 and 14,980 pounds respectively. They were both shipped from the Augusta Arsenal in 1872 as part of the US Army's efforts to rebuild Fort Moultrie in the 1870s. By the late 1890s, these two Civil War era cannons were obsolete. They were ordered scrapped, but instead they were simply buried at the fort. Excavations in 1974 in the area of the fort's original barracks uncovered them along with two 8-Inch Parrotts and a 15-Inch Rodman.
The original carriages of one or both of these Rodmans may survive at White Point Garden in Charleston where US Army carriages are used to display Confederate cannons in the "Battery" at the park. https://www.santee1821.net/preserved-artillery/uss-keokuks-dahlgren-and-the-rodman-carriage
