1. The Maryland Campaign of September 1862, Volume II: Antietam edited by Thomas G. Clemens (Savas Beatie, 2012).
It is no surprise that this is shaping up to be a big month for Antietam fans, with the highly anticipated release of this book, the Antietam atlas from the same publisher, and Scott Hartwig's new campaign history.
2. Mending Broken Soldiers: The Union and Confederate Programs to Supply Artificial Limbs by Guy R. Hasegawa (SIUP, 2012).
