Is this your man? According to the site:
"James B. Lunsford was born in East Tennessee in 1840, and resided there until 1852 when he came to North Carolina where he remained two years. When fourteen years of age he came to Texas and resided in Harrison and Rusk counties until 1860, when he went to Dallas, living in the western part of that county until his enlistment in Douglas' Battery. In the capacity of a private soldier, he served the Confederacy every day of the war, participating in every battle and skirmish in which his company was engaged, with the exception of the engagement across Duck River, on Nov. 29, 1864. This duel and show of force was for the double purpose of attracting the attention of the enemy and of permitting the execution of a flanking and intercepting movement to the left and rear of the enemy as they faced the Confederates. Young Lunsford was detailed to serve with an improvised artillery company on this expedition – which unfortunately proved to be fruitless – and so missed the battle of Columbia . He escaped all casualties during the war excepting a slight wound from a bursting shell at Elkhorn. He had, too, a horse killed from under him while acting as one of the drivers at Richmond , Ky. He was captured December 17, 1864, on the retreat from Nashville and was surrendered with the other troops at Gainesville, Alabama , on the eighth day of May, 1865. On account of the unsettled conditions of the times he decided to return to North Carolina and has since resided there."
