I suspect that these two are the same individual and the confusion arrises from bookkeeping errors.

The 6th Mississippi was in January, 1865, assigned to Wood’s/Adam’s Cavalry located in the Vicksburg/Jackson area. I suspect that Pvt. Carradine was in the hospital at Canton when his regiment was reassigned to Starke’s Brigade and sent to Alabama where they were surrendered and paroled at Gainesville, Ala.

I suspect that the record of his parole at Gainesville was in error and he was recorded on the roll from a copy of his companies muster roll.

I have no explanation as to the listing of Palo Alto as his residence.

...

B. C. Carradine, Private, Company C, 6th Mississippi Cavalry, resident of Palo Alto, Chickasaw County, Miss., was surrendered with Company C, 6th Regiment of Miss., Cavalry, CSA, commanded by Col. R. Y. Brown, surrendered at Citronelle, Ala., by LGen. R. Taylor, CSA, to MGen. E. R. S. Canby, USA, May 4, 1865, and paroled at Gainesville, Ala., May 12, 1865, Roll dated Gainesville, Ala., May 12, 1865

Note: This is the one and only card in his file.
