It appears from the OR's that Palmer was, in Dec. 1864, operating with Forrest opposite Murfressboro. A report detailing the activities can be found in the Official records, Seris 1, Vol. 45-part 1, starting on page 744. our local library should have a copy of the OR's or they can be accessed on line at:
