Battle of AntietamColonel Post was wounded. From the brigade marker on the Antietam battlefield: Phelps’ Brigade formed line at 5:30 A. M. on September 17, and moved in support of Gibbon’s Brigade. When Gibbon deployed, 135 yards north of this in the Cornfield and on the plateau west of the Hagerstown Pike, Phelps’ Brigade (425 officers and men) halted 25 paces in his rear, in the Cornfield. After Gibbon advanced and became heavily engaged on both sides of the Pike, Phelps moved to the support of his left and fought on this ground.
