Carl, I recall getting an email from you on the 38th Arkansas, but I either accidentally deleted it, or my computer gremlins ate it, or something; anyway, I lost it.
Thanks for the citation of Banasik's assertion regarding the 38th Arkansas at Prairie Grove. That's very helpful, because the records of the 38th Arkansas make no mention of that action. The muster rolls have a gap between their initial muster-in rolls in the summer of 1862 and the March-April 1863 bimonthly rolls -- everything in between is missing.
None of the surviving rolls mention anything about Prairie Grove, nor any casualties, prisoners, etc., from any actions in December 1862.
Several years ago I did some exhaustive research on Company G -- five of my g-g-grandfathers and a whole host of brothers, uncles and cousins served in the company -- and found nothing in the way of letters or any other documents which mention Prairie Grove. My ancestors passed down some oral traditions about their service in Co. G, 38th Arkansas, but nothing about Prairie Grove.
Sorry about dropping the ball on your email, but I don't know what's happening with this computer most of the time -- I'm just along for the ride.
