Nicely done. Is your book on Arkansas infantry units done the same way to be downloaded?
Also - the flag you have for Dobbins' 1st Arkansas Cavalry is not considered a Polk Corps flag by us flag historians as they never served in Polk's Corps for one, and, secondly, it is a bit different. The late Howard Madaus deemed it a Trans-Mississippi pattern unique to that theater. One other flag of the same style exists in the Iowa collections captured at Helena in July 1863.
Great work!
