Glad the Inman material was helpful.
You're probably correct about this man being a conscript. Those who took the oath were instructed to remain north of the Ohio River, but most headed for home. That may be the case here.
I misunderstood; you were saying that Confederate officers took parole papers from members of Vaughn's old brigade (before they reorganized for mounted service). That may be, but I can't confirm or deny this.
