First Army Corps

On September 17, 1862, Phelps' Brigade of Doubleday's Division in the U.S.A. First Army Corps, commanded by Col. Walter Phelps of the 22d New York Infantry and composed of the 22d, 24th, 30th, and 84th New York Infantry and 2d U.S. Sharpshooters, formed line at 5:30 a.m. and moved in support of Gibbon's Brigade. When Gibbon deployed 135 yards north of this position in the cornfield and on the plateau west of the Hagerstown Pike, Phelps' Brigade, with 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 support his left and fought on this ground. The brigade's subsequent movements conformed to those of Gibbon, and after heavy loss it retired to the fields north of D.R. Miller's and then beyond the Poffenberger Lane.
