CSS Stonewall Jackson was a cotton-clad sidewheel ram of the Confederate Navy during the American Civil War. Stonewall Jackson was selected in January 1862, by Capt. James E. Montgomery to be part of his River Defense Fleet at New Orleans. On 25 January Montgomery began to convert her into a cottonclad ram by placing a oak sheath with iron covering on her bow, and by installing double pine bulkheads fitted with compressed cotton bales.
