Series I, Volume 41 (4 parts) covers the Missouri Expediton. Have you looked at those yet? It has Price's complete report (pg 625) on battles and you might be able to glean the different battles the Arkansas units were involved from that. It also has a detailed itenerary, day by day. I didn't find the exact thing you were looking for in my quick review but I would think it might be there somewhere. It is not on any page 1118 of any of the 4 parts however.
