May 1864. The Army of the Potomac and the Army of Northern Virginia spent three days in brutal close-quarter combat in the Wilderness that left the tangled thickets aflame. No one could have imagined a more infernal battlefield—until the armies moved down the road to Spotsylvania Court House.

Even the march itself was unprecedented. For three years the armies had fought battles and disengaged after each one. That pattern changed on the night of May 7. Instead of leaving the Wilderness to regroup, Lt. Gen. Ulysses S. Grant led the Federal army southward, skirmishing with Confederates all the way. “There will be no turning back,” he had declared. He lived up to his word. By dawn on May 8, the armies had tussled their way ten miles down the road and opened another large-scale fight that would last until May 21. “One thing is certain of this campaign thus far,” explained Dr. Daniel Holt of the 121st New York: “More blood has been shed, more lives lost, and more human suffering undergone than ever before in a season.”

The fighting launched a score of new place-names and events that would sear themselves into the American consciousness, such as Spindle Field, Upton’s assault, the Mule Shoe, the Bloody Angle, and the Harris Farm. The casualties exacted at Spotsylvania exceeded those of the Wilderness by thousands. The fighting severely tested the offensive capabilities of Gen. Robert E. Lee’s Southern army, just as the defensive posture his men embraced would, in turn, test the limits of Federal endurance.

A Tempest of Iron and Lead: Spotsylvania Court House, May 8–21, 1864 is a comprehensive and comprehensible study of this endlessly fascinating campaign. Author Chris Mackowski is intimately familiar with the battle of Spotsylvania Court House.
