The struggle over the fortified Confederate position known as Spotsylvania's Mule Shoe was without parallel during the Civil War. A Union assault that began at 4:30 A.M. on May 12, 1864, sparked brutal combat that lasted nearly twenty-four hours. By the time Grant's forces withdrew, some 55,000 men from Union and Confederate armies had been drawn into the fury, battling in torrential rain along the fieldworks at distances often less than the length of a rifle barrel. One Union private recalled the fighting as a "seething, bubbling, soaring hell of hate and murder."

James Longstreet's countermarch and Samuel Johnston's morning reconnaissance are two of the most enigmatic events of the Battle of Gettysburg. Both have been viewed as major factors in the Confederacy's loss of the battle and, in turn, the war. Yet much of it lies shrouded in mystery. Recognizing the multitude of factors that affect human memory, In the Shadow of the Round Tops explores how the individual soldiers experienced, remembered, and wrote about the battle, and how those memories have created a cloud over James Longstreet's countermarch and Samuel Johnston's reconnaissance.

It was the most remarkable political about-face in American history. During the Civil War, General James Longstreet fought tenaciously for the Confederacy. He was alongside Lee at Gettysburg (and counseled him not to order the ill-fated attacks on entrenched Union forces there). He won a major Confederate victory at Chickamauga and was seriously wounded during a later battle. After the war Longstreet moved to New Orleans, where he dramatically changed course.

At the outset of the Battle of the Wilderness, General Lee's Army of Northern Virginia remained capable of defeating the Army of the Potomac. After two days of relentless fighting in dense Virginia woods, Robert E. Lee was never again able to launch offensive operations against Grant's army. This battle was one of the most gruesome in American history. The impenetrable forest and gunfire smoke made it impossible to view the enemy. Officers couldn't see their own men during the fighting. The incessant gunfire caused the woods to catch fire, resulting in hundreds of men burning to death.

It was the largest campaign ever attempted in the Civil War: the Peninsula campaign of 1862. General George McClellan planned to advance from Yorktown up the Virginia Peninsula and destroy the Rebel army in its own capital. But with Robert E. Lee delivering blows to the Union army, McClellan’s plan fell through at the gates of Richmond.
