However, I have found some interesting information on the unit. Joseph Barbiere, formerly of the 1st Alabama wrote a book on his prison experiences at Camp Chase.
Barbiere's Reserve Cavalry - 571 men
Barbiere's reserve cavalry consisted of six companies under the command of Maj. Joseph Barbiere, and served principally in central Alabama during the fall and winter of 1864-65.

Near this site are the remains of three forts built in 1863 by Confederate troops under the command of Major W.T. Walthall, commander of the military post at Talladega. The forts, built for protection of the Alabama-Tennessee River Railroad trestles across the Coosa River and Yellow Leaf Creek, were manned during the last months of the war by reserve companies consisting of young boys and old men. Barbiere's Reserve Cavalry was stationed here in February 1865. Union troops commanded by General James H. Wilson captured the forts in March 1865.
