Gordon C. Rhea 
Battle of the Wilderness, May 5-6, 1864 [PDF ebook] 

Fought in a tangled forest fringing the south bank of the Rapidan River, the Battle of the Wilderness marked the initial engagement in the climactic months of the Civil War in Virginia, and the first encounter between Ulysses S. Grant and Robert E. Lee. In an exciting narrative, Gordon C. Rhea provides the consummate recounting of that conflict of May 5 and 6, 1864, which ended with high casualties on both sides but no clear victor. With its balanced analysis of events and people, command structures and strategies, The Battle of the Wilderness is operational history as it should be written.
