Further, you can find a four page sketch of the regiment in "Military Annals of Tennessee, Confederate" edited by John Barrian Lindsley, Broadfoot Publishing Co., Wilmington , NC, 1995 and I would also guess in "Tennesseans in the Civil War, Part 1, Civil War Centennial Commision of Tennessee, 1965.
