By the spring of 1864, the Army of the Potomac and the Army of Northern Virginia had become battle-hardened, battle-weary foes locked in an ongoing stalemate. With the presidential election looming in the fall, President Abraham Lincoln needed to break the deadlock and so brought to the east the unassuming "dust-covered man" who had strung together victory after victory in the west: Ulysses S. Grant.   "Well," said soldiers in the Army of the Potomac with a grudging respect for their Southern adversary, "Grant has never met Bobby Lee yet."   Robert E. Lee and Ulysses S. Grant would come to symbolize the armies they led as the spring campaign got underway, and the clash that began in the Virginia Wilderness on May 5, 1864, turned into a long, desperate death-match that inexorably led to Appomattox Court House eleven months later.   The war would come to an end, but at what cost along the way?   Grant vs. Lee: Favorite Stories and Fresh Perspectives from the Historians at Emerging Civil War recounts some of the most famous episodes and most compelling human dramas from the marquee match-up of the Civil War - not just the two most successful commanders produced by either side but the two largest and most fabled armies of the war.
