Fourth U.S. Infantry

As part of the Army of the Potomac's Fifth Corps, Second Division, First Brigade, the Fourth U.S. Infantry, consisting of four companies under Captain Julius W. Adams Jr., arrived on July 2 and took position near the line of the Twelfth Corps. The regiment, with the brigade, moved from the right to the left of the line and at 5 p.m. advanced across Plum Run near Little Round Top, supporting the Second Brigade in its advance to the crest of the rocky wooded hill beyond. Facing left, it engaged the Confederates but retired under deadly fire on both flanks and from the rear after the Confederates gained a position in the Wheatfield behind the brigade. On July 3 it remained in the same position. On July 4 the regiment, with the brigade, made a reconnaissance, developed a force of Confederate infantry and artillery in front, and engaged on the skirmish line well to the front. Its casualties were 10 men killed, 2 officers and 28 men wounded.
