In the Battalion Reserve Artillery, I believe the "1st Missouri Battery" commanded by Capt. B. Wade is actually the 1st Mississippi Light Artillery (Battery E). While there was a 1st Missouri Light Artillery Battery commanded by Capt. William Wade, they were not in the TMD in 1865. Capt. Wade had been killed at Grand Gulf, MS on April 29, 1863 and the remainder of the battery was incorporated into Guibor's MO Battery which saw service with the AOT until its surrender.
"Wade's Battery E, 1st Mississippi Light Artillery", was the only Mississippi unit to serve in the TMD. Moreover, "Mississippi A" buttons have been found in an 1864 encampment of Wade's Battery in SW Arkansas.
Just thought I'd throw that in to help clarify the record.
