Third Brigade

Third Brigade of the Army of the Potomac's Twelfth Corps, First Division, under Brig. Gen. Thomas H. Ruger and Col. Silas H. Colgrove, included the 27th Indiana, 2d Mass., 13th New Jersey, 107th New York, and 3d Wisconsin Infantry. On July 1 it arrived with the division and bivouacked for the night east of Rock Creek. On July 2, after sharp skirmishing in front, it crossed Rock Creek and took position with its left on Culp's Hill and its right in McAllister's Woods, with a swale between, and constructed breastworks. At sunset it went to support the left of the army and, on returning, found the works on the left of the swale occupied by Confederates; those on the right were unoccupied and were immediately re-possessed. On July 3, the 2d Mass. and 27th Indiana charged across the open swale in the morning to gain a stone wall and woods on the left, but were repulsed with great loss, the 27th Indiana falling back in a direct line and the 2d Mass. toward the left. A Confederate counter-charge then crossed the swale, but under front and enfilading fire it was quickly repulsed, and the Confederate force left the works and retired across Rock Creek. On July 4, with a battery and three regiments of the First Brigade, it made a reconnoissance in front and around through the town after the Confederate forces had withdrawn to Seminary Hill. Its casualties were 2 officers and 47 men killed, 20 officers and 205 men wounded, and 5 men captured or missing, for a total of 279.
