The hard copy records in his CSR file, compiled by the US War Department ca 1900 were taken from then extant Confederate records.

Your Comment:
'It has what must certainly be other errors, such as dating his Coatzacoalcos confinement 6-9, the day after he was taken captive at Cross Keys."
Note carefully, there is no statement as to the date he was taken onboard the Steamer C.
Card #5 His name appears on a Roll of prisoners on board Steamer Coatzacoalcos, NOT DATED, taken prisoner June 8, 186_ at Cross Keys
