I suspect he was buried in the Friendship Cemetery located in Columbus, Miss.

During the American Civil War, Columbus served as a military hospital center for the wounded, particularly after the Battle of Shiloh.[6] More than 2,000 Confederate soldiers were interred in Friendship Cemetery,[7] along with 40 to 150 Union soldiers.[8]:127
