1. Patrick Connor's War: The 1865 Powder River Indian Expedition by David E. Wagner (Arthur H. Clark Co., 2010).
Wagner, who passed away last year, recently published an edited volume of journals from one wing of the multi-pronged 1865 Powder River Expedition directed against the Sioux, Cheyenne, and Arapaho. This book also draws heavily upon participant accounts, but here the author attempted to reconstruct the campaign as a whole. Large numbers of maps will allow the reader to follow the action over great expanses of unfamiliar terrain.
2. A Hard Trip: A History of the 15th Mississippi Infantry, CSA by Ben Wynne (Mercer U. Press, 2010).
3. The Battle of Resaca: Atlanta Campaign, 1864 by Philip L. Secrist (Mercer U. Press, 2010).
The above pair of Mercer titles are new paperback reprints. Unread by me, both are welcome. The Resaca book is a brief summary, with some interesting battle maps and photography.
