 The Union XII Corps was formed in June 1862. The corps, which joined the Army of the Potomac only a week before Antietam was small, numbering just over 7,600 men. Easily overlooked, Army of the Potomac leadership and historians since have largely glossed over this corps’ contribution at Antietam. Nevertheless, this small corps ended Confederate attacks into the Miller Cornfield and East Woods, successfully defended the Dunker Church Plateau from Confederate assaults, and captured the West Woods, which had been the goal on the Federal right all morning. Chris Bryan will provide a brief overview of the period from the Battle of Cedar Mountain until the corps’ entry into Maryland, including its condition resulting from this period. The talk will then examine the XII Corps’ participation in the Maryland Campaign and its fighting at Antietam, including some new findings discovered through recent archival research. 

M. Chris Bryan’s Cedar Mountain to Antietam: A Civil War Campaign History of the Union XII Corps, July –September 1862 begins with the formation of this often-luckless command as the II Corps in Maj. Gen. John Pope’s Army of Virginia on June 26, 1862. Bryan explains in meticulous detail how the corps endured a bloody and demoralizing loss after coming within a whisker of defeating Maj. Gen. “Stonewall” Jackson at Cedar Mountain on August 9; suffered through the hardships of Pope’s campaign before and after the Battle of Second Manassas; and triumphed after entering Maryland and joining the reorganized Army of the Potomac. The men of this small corps earned a solid reputation in the Army of the Potomac at Antietam that would only grow during the battles of 1863.
