During the contest at Fox's Gap, Hooker's First Corps operated east and northeast of this point. The First Corps left the Monocacy at daybreak, passed through Frederick and Middletown, and between 3 and 4 P. M., leaving Gibbon's Brigade on the main pike, turned right at Bolivar, nearly two miles southeast of this point, marched on the old Hagerstown road, passed Mt. Tabor Church, and formed line about one and a quarter miles east of this point, with Meade's Division on the right, Hatch's on the left, and Ricketts' in reserve. By Hooker's advance, Rodes' Brigade was driven from its position on several prominent mountain peaks, and the Union advance gained ground to the left and front. During the action Longstreet arrived from Hagerstown with reinforcements, and the brigades of Kemper, Garnett, and Evans went to Rodes' assistance, but the whole Confederate line east and northeast of this point was forced back, and at dark the First Corps held the summit and the high ground commanding the road, threatening the Confederate line of retreat.
