Daniel N. Moody was the first elected captain of the Volunteer Southrons, organized at Vicksburg May 15, 1861, it soon was designated Company A of the 1st Battalion (Brandon's) Mississippi Volunteers, subsequently Co. A, 21st Mississippi Infantry Regiment. He was promoted first to major, then lieut. colonel, and then to colonel of the regiment. For a unit with records as nearly complete as this one, I'm surprised that we can find no record of Rockwood's service in the unit.
