After Gettysburg: Cavalry Operations in the Eastern Theater July 14 1863 to Dec 31 1863 by Robert J. Trout (Eagle Editions, Ltd., 2012).
Trout's book covers cavalry operations in the main theater in the east during the six months following Gettysburg. It features the battles of Shepherdstown, Brandy Station, Bristoe Station, Mine Run and host of other skirmishes fought before winter set in. The maps and research impress at first glance, and the material quality, with its old fashioned heft, is quite noteworthy. To cap it off, the price is very reasonable.
