On the following link is a photo of a group of men in good uniforms and some sort of short barreled weapon with bayonets attached. The web site says its Captain Benjamin Stevens Troops of the 9th MS. Cav. from Perry County. That would be Co. D. This photo looks post Civil War to me. If is not, and is from the Civil War, its one of the greatest photos of Confederates soldiers identified from Mississippi I've seen.
