Doubleday's Division, First Army Corps,
Brigadier Gen. Abner Doubleday, Commanding.
(September 17, 1862.)Doubleday's Division, on the right of the First Corps, moved to the attack at 5/30 a.m., September 17, in the following order: Gibbon's Brigade in advance, supported by Phelps' and Patrick's Brigades. Hofmann's Brigade was held in reserve. The three brigades of Gibbon, Phelps and Patrick - advanced, their right resting on the Hagerstown Pike, until Gibbon reached a point 135 yards north of this, when his right flank was fired into by the Confederate skirmishers posted behind a ledge west of and parallel to the Pike. The Division was then deployed, Gibbon across the turnpike with Battery B, 4th U.S. Artillery, in his right rear; Phelps moved upon Gibbon's left and Patrick crossed to the west of the turnpike and supported Gibbon's right and the battery. The three brigades became heavily engaged, advancing to and south of this point. After an obstinate contest of over an hour, with varying success, the brigades were withdrawn to the fields north of D.R. Miller's and, subsequently, to the cover of the high ground beyond Joseph Poffenberger's.
