"Grinding, bloody, and ultimately decisive, the Petersburg Campaign was the Civil War's longest and among its most complex. A Campaign of Giants: The Battle for Petersburg offers a gripping, comprehensive history of the decisive campaign in the eastern theater. In this second of three volumes, A. Wilson Greene narrates the critical months from August through October 1864, during which Ulysses S. Grant’s army group launched three major offensives against Robert E. Lee's defenses around Petersburg and the Confederate capital in Richmond. The Confederates counterpunched after each Union advance and conducted a spectacular cavalry raid that netted almost 2,500 cattle from Federal grazing grounds. But as winter approached, Grant had captured one of Lee’s primary supply routes and extended the lines around Petersburg and Richmond to some thirty-five miles."-- From Amazon.
