I also found F. M. Box in Powers' Cavalry. My F. M. was from Newton County, although the 1860 census places him in Jasper County, just below the state line. His family, and apparently his loyalties, rested in Newton County. He did not mention Powers' Cavalry in his pension application. His references were only to the Newton Hornets. He does mention sustaining an injury while "putting a pontoon bridge across the Tennessee River at Muscle Shoals." I believe that would have placed him with the 39th MS on the retreat after Franklin unless there was another time when the Army of Tennessee crossed the Tennessee at Muscle Shoals. Franklin was November 1864 and Powers' raised his Mississippi regiments in late 1863.

Powers' Regiment would have placed him in the vicinity he stated more so than with the 39th. The War Department record shows him on the rolls of the 39th through 31 August 1864 and then falling off the records. I want to theorize that he served with Powers' Regiment after Hood destroyed the army at Nashville and it fell back into northern Mississippi. Unfortunately, I do not know enough about the Army of Tennessee to be able to map the retreat and determine if that is an actual possibility.
