Phelps' Brigade, Doubleday's Division

   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. The subsequent movements of this Brigade conformed to those of Gibbon. After heavy loss it retired to the fields north of D. R. Miller's and thence beyond the Poffenberger Lane.
