7. Gregg's Brigade Position
Looking west from the tablet location. For most of July 3, 1863, Gregg's Brigade occupied positions to the west of the tablet location, along Hanover Road, seen here on the left side of the photo. Monuments to the regiments in the brigade are posted from near the south entrance to the East Cavalry Battlefield (1st Maine Cavalry), westward to near the modern US Highway 15 bypass (10th New York Cavalry). The 16th Pennsylvania Cavalry Monument stands on Highland Avenue even further to the west of the Highway 15 bypass.
The placement of these monuments gives some measure of the distances covered by a cavalry brigade active in flank screening operations during a major battle.
