During the summer and fall of 1864, Virginia's Shenandoah Valley was one of the most contested regions of the South. Federal armies invaded the Valley three times - twice they were repulsed. This book describes the third campaign, the supreme achievement of the Army of the Potomac's Sixth Corps. One of the most respected units in the U.S., the Sixth advanced on the heels of retreating Confederate forces through sweltering heat and some of the most terrible fighting of the war, winning a string of victories (some costly) from the Wilderness and Spotsylvania to Cold Harbor and Cedar Creek.
