This information from "Encyclopedia of Forts, Posts, Named Camps and Other Military Installations in Louisiana, 1700-1981" by Powell A. Casey.
Camp Buckner " '...near Pineville' or '2 1/2 miles north of Alex,' was probably named for Confederate General Simon Bolivar Buckner. One account said that it had hutments. The Consolidated Crescent Regiment seems to have been there from July 20, 1864 until the end of the war."

My GGGrandfather's service record states, "On Return dated Camp Buckner, Alexandria, Dec. 31, 1864, age 30, eyes black, complexion dark. height 5 ft. 7 in., born Alabama, occupation farmer. Killed in action, Mansfield, April 8, 1864." I don't know what that return or report was; maybe someone could help us out with that. I would like to find a transcript of it for the whole regiment.
