Epic Chickamauga trilogy

Having neither the spare room available nor a clinically diagnosable hoarding instinct, I'm not one to keep every single Civil War book that I acquire in one manner or another. Taking into account both personal interest and shelving limits, for many subjects I am content to have the best available treatment and good riddance to everything else. If something better comes along, it's out with the old and in with the new. In the military campaign sphere, Chickamauga for me is pretty much 'keep the best, chuck the rest'. With the latest Savas Beatie newsletter announcing the first volume of David Powell's trilogy -- The Chickamauga Campaign—A Mad Irregular Battle: From the Crossing of the Tennessee River Through the First Day, August 22-September 19, 1863 -- it looks like some shelf cleaning is in the future [the Chickamauga atlas, of course being immune]. In my opinion, if the tale of Chickamauga is to be told in epic fashion the person for the job is either William Glenn Robertson or David Powell, and the fact that the latter is actually doing it is a source of great satisfaction.
