Through the winter of 1862 and spring of 1863, the U.S. Army and Robert E. Lee's Army of Northern Virginia clashed along the Rappahannock River in two major battles. Both demonstrated the height of power for the Confederacy in the eastern theater. The Battle of Fredericksburg was a tactically defensive triumph for Lee over the Army of the Potomac. The Battle of Chancellorsville, often described as Lee's masterpiece, was a surprisingly aggressive response to Joseph Hooker's operational flanking maneuver, as Lee sent Thomas J. "Stonewall" Jackson on a flanking maneuver of his own, dividing an army that already was substantially smaller than its Union counterpart to deliver a crushing blow at a decisive spot. It was in the latter stages of that blow that Jackson was mortally wounded by his own men. The battles, failed campaigns with high casualty rates for the Union, were a lead-up to the armies' meeting at Gettysburg in July 1863. Civil War historian Brian K. Burton provides a clear, concise narrative of the battles and offers a stop-by-stop guide through Fredericksburg and Spotsylvania National Military Park. Illustrated with numerous maps and filled with stories of the people and tactics of both battles, this indispensable guidebook will direct battlefield visitors and armchair historians through the events of these pivotal campaigns.
