Doyle-Very interesting post. 19/24/Hardys was my g-g-grandfathers regiment so I have an interest. In scanning the roster for the 24th Ark. It looks like the enlisted POW's were sent to camp Douglas-but were the officers sent elswere? The reg. bios for Hardy and Portlock say "Camp Chase OH, Ft. Delaware DE then City Point VA" for exchange. If correct would not those "detainees" have a "paroled in field" designation? I know from your excellent research on this unit that around 200 men went from St. Charles to Arkansas Post arriving in time to be captured-and that St. Charles was their "permanant duty station" as listed in the bios. for the reg. surgeon and Post QM. Any way might there be a record of such a parole on the Union side? Very interesting thread...
