David --

Thaks for your efforts in putting all this information together. Once a soldier took the oath of allegiance, if ever captured again, Federal authorities could have him shot or hung. That was also true for paroled prisoners who had not been exchanged.

I really can't think of another instance in which a Confederate soldier returned to his unit after taking the oath of allegiance. No doubt this man was wounded, but without contemporary evidence to the contrary, the statement of his company commander on the roll must be considered authoritative.
