OK adding to my confusion if you go to the NPS Vicksburg (Ark. Post is officially part of the Vicksburg campaign) web site the 19th Ark. is listed as attched to Col. John Dunningtons 3rd Brigade commanded by Dawson at Ark. Post yet are listed as assigned to Martin Greens brigade at Vicksburg. Were they paroled at Ark. Post only to show up later at Vicksburg? Or is the 19th a "split" unit like the 24th-that after Ark. Post-part remained in Ark. and part served with the army of Tennessee? My head is spinning-I have to sit down...
