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 Шаблон:Convert oak sheath with Шаблон:Convert iron covering on her bow, and by installing double pine bulkheads fitted with compressed cotton bales.
Stonewall JacksonШаблон:'s conversion was completed on 16 March 1862. Under Capt. G. M. Phillips she was detached from Montgomery's main force and sent to Forts Jackson and St. Philip on the lower Mississippi to cooperate in the Confederate defense of New Orleans. There, with five other vessels of Montgomery's fleet, all under Capt. J. A. Stevenson, she joined the force under Capt. J. K. Mitchell, CSN, commanding Confederate naval forces in the lower Mississippi.
On 24 April 1862 a Union fleet under Flag OfficerDavid Farragut, USN, ran past Forts Jackson and St. Philip on its way to capture New Orleans. In the engagement Stonewall Jackson rammed Шаблон:USS, which had already been struck by Шаблон:Ship. With VarunaШаблон:'s shot glancing off her bow, Stonewall Jackson backed off for another blow and struck again in the same place, crushing VarunaШаблон:'s side. The shock of the blow turned the Confederate vessel, and she received five 8-inch shells from Varuna, abaft her armor. Varuna ran aground in a sinking condition, and Stonewall Jackson, chased by Шаблон:USS coming to VarunaШаблон:'s rescue, was driven ashore and burned.
