Thanks Bryan, I learn so much from this site. I hadn't heard of Leeper's book. I'll find a copy.
Others may be interested in this book.
The second part of Willis' "Arkansas Confederates in the Western Theater" covers the D.H. Reynolds Arkansas Brigade after Missionary Ridge. This Brigade includes the 1st and 2nd Rifles, the 25th and the 4th, as well as the 9th Ark. Infantry (which the book is following). Reynolds was promoted from the 1st Ark. Rifles. This book is a great reference to the last year of the war; Information which is so hard to find for these regiments.
