The heavy fog that shrouded Antietam Creek on the morning of September 17, 1862, was disturbed by the boom of Federal artillery fire. The carnage and chaos began in the East Woods and Cornfield and continued inexorably on as McClellan's and Lee's troops collided at the West Woods, Bloody Lane and Burnside Bridge. Though outnumbered, the Rebels still managed to hold their ground until nightfall. Chief historian of the Antietam National Battlefield, Ted Alexander renders a fresh and gripping portrayal of the battle, its aftermath, the effect on the civilians of Sharpsburg and the efforts to preserve the hallowed spot.
