Danny,
The official returns for the forces in Pryor's Brigade may be found in the Official Records, Series 1, Volume XVIII, Page 807. At that time Brig. Raleigh Colston was Brigade Commander, the command was passed to Pryor, who I believe was later relieved. This brigade served in G Elzey's/French's Command. Here is the makeup of the brigade as of Dec. 20, 1862.
54th Virginia Infantry Regiment, Col. Robert C. Trigg
27th Virginia Cavalry Battalion, Col. Henry A. Edmundson
50th Virginia Infantry Regiment, Col. Thomas Poage
29th Virginia Infantry Regiment. Col. Alfred C Moore
63d Virginia Infantry Regiment, Col. James J. McMahon
