1. Touring the Carolina's Civil War Sites 2nd Ed. by Clint Johnson (John F. Blair, 2011)
2. Touring Virginia's and West Virginia's Civil War Sites 2nd Ed. by Clint Johnson (John F. Blair, 2011).
These are state wide touring books broken down into day trip sized chunks. I've never seen the first editions of these works so an assessment of improvements made can't be made by me.
3. Battlefield Angels: Saving Lives Under Enemy Fire From Valley Forge to Afghanistan by Scott McGaugh (Osprey Publishing, 2011).
This book examines the history of U.S. military medicine through theme based chapters centering on specific conflicts. The Civil War chapter looks at battlefield evacuation.
