He had been a State legislator relatively young, serving from 1846-52 in the House, then 1854-88, and 1860-61 in the State Senate. He raised a Company in what became the 2nd South Carolina State Troops, and was elected Major of that regiment. When the unit transitioned to Confederate service he was left without a command. He then raised what became Company I, 12th South Carolina at Lancaster County Court House, and was their Captain. He was elected Lieutenant Colonel after that Regiment formed in July 1861 in Lightwood Knot Springs, about 5 miles north of Columbia. He was promoted Colonel when Colonel Dunnovant resigned in May 1862.
On the Campaign
Courtly, white haired Colonel Dixon Barnes had been put under arrest by Jackson for allowing his hungry men to take apples from a tree against orders, and Gregg [his brigade commander] felt he could not release him from the arrest. Pale and stern faced, [A. P.] Hill said 'General Gregg, I order you to give Colonel Barnes his sword and put him in command of his Regiment." Barnes was thus placed back in command of the 12th South Carolina. Barnes had been willing to serve in the ranks rather than miss the fightHe was mortally wounded, shot through both knees in action at Sharpsburg on 17 September 1862.
The rest of the War
He died of wounds at Charleston, VA (now WV) on 27 September 1862.
