In a message by General Sherman to General Grant around the 19th of July 1863. He states that Johnston has dug in and fortified Jackson, Mississippi. The defences he states include large rifled guns that were doing some damage to his forces. After Johnston evacuated Jackson, Sherman wrote he acquired these guns and the ammunition. He then abandoned Jackson after destroying what he could, and blew the ammunition and the guns into the Pearl River. Has does anyone know what happened to these weapons?
