Although Jim Miles probably covered it to some extent in one of his myriad of touring books, the Battle of Murfreesboro still has no book length battlefield guide devoted to it. However, in December 07, the Spruills's Winter Lightning: A Guide to the Battle of Stones River (University of Tennessee Press) will be published. Previous collaborative efforts from the author cover The Seven Days, Chickamauga, and Chattanooga.
Readers familiar with the US Army War College Guide series will recognize the structure. While I own many of them and have found them to be useful, I have mixed feelings about the O.R. text heavy format. In general, the series published by the University of Nebraska Press comes closer to what I want in a field guide: maps (and more maps), concise text, photos, and detailed orientation information.
