Regardless, whatever happened, he failed to enter the 9th MS Inf. Regiment.
But his entry (assuming it is the same person) into Co K, Wood's Regiment of Confederate Cavalry also contains some curious remarks. This Company Muster Roll for July 1 to Oct. 31, 1862, records Richard M. Bridges enlisted in Aug 1862, yet was paid by Capt. Maurice to June 30, 186_.
One of these entries must be incorrect. I don't believe the CSA was paying men for service prior to enlistment.
The Wood's Regimental Return for May to Oct, 1862, records his return on 14 Aug. 186_, at Guntown, "By transfer Gain."
This makes me believe that Wood's Regiment was aware R. Bridges wasn't a new enlistee, but had a previous military service record with another unit. I assume this was his service with the 10th MS.
His desertion (Oct. 1863) from the 46th MS after the fall of Vicksburg is more difficult to defend.
