2. Report of Brig. Gen. Thomas H. Ruger. Gen. Ruger included a simple map of the area around Culp's Hill in his report. Of the action on July 2, he wrote:
The Twentieth Connecticut Volunteers, supported by the One hundred and seventh New York Volunteers, First Division, was thrown forward from the left of the division into the woods in rear of the stone wall held by the enemy. The general relation of the lines of the First and Second Divisions of the corps was a two-sided, truncated triangle, the apex at which point was the battery from the enemy, the ends toward the enemy inclining to the right and left, respectively, and too strong to be carried, Rocky Run protecting the right and strong breastworks occupying the left....

This state of things continued until about 10 a.m., the enemy maintaining the attack with great constancy, throwing forward fresh troops from time to time, suffering severely, but gaining no advantage, while our loss was comparatively slight. At this time I received orders to try the enemy on the right of the line of breast, works, to the left of the swale, with two regiments, and, if practicable, to force him out. I sent orders by a staff officer to Colonel Col-grove, commanding Third Brigade, to advance skirmishers against the enemy at that point, and, if not found in too great force, to advance two regiments, and dislodge him from the breastworks. From mistake of the staff officer, or misunderstanding on the part of Colonel Colgrove, it was attempted to carry the position without first ascertaining the force of the enemy. The regiments selected--the Second Massachusetts Volunteers and Twenty-seventh Indiana Volunteers, of Third Brigade--moved forward gallantly, crossed the swale in line under a severe fire, gained the woods on the opposite side, forced the enemy back part way up the slope to breastworks, but could not dislodge him, owing to the natural obstacles to the advance and heavy fire of the enemy from his well-protected position. The regiments were withdrawn. The enemy attempted to follow, but was quickly driven back by the two regiments, who turned and opened fire, assisted by their supports.
