July 2. Arrived and took position on Hanover Road 2 miles from Gettysburg in proximity to Lieut. Gen. Ewell's Corps about 11 A. M. Two regiments of infantry from Eleventh Corps were in front as skirmishers. They were withdrawn about 3 P. M. and 10th New York deployed in their place. Confederate sharpshooters from hill and woods in front were annoying. Fifty dismounted men were ordered to drive them back but were themselves met by a superior force until checked and forced back by First Brigade.
