This is the story of the battle of Antietam and the events leading up to the single bloodiest day in the entire Civil War. Union casualties topped 12,000 and Confederate casualties topped 11,000, and such memorable figures of military history as Lee and McClellan, as well as Burnside, Longstreet, Hooker, and Jackson, all took part. Promise of Glory is the story of these men, their officers, and the soldiers of both armies, who so valiantly served their cause. C. X. Moreau has faithfully created their common history and brought to life the drama and the tragedy of Antiedam.
