When the 3rd Corps collapsed on the afternoon of July 2nd, several units were sent into the area of the Wheatfield to try and stop the Condeferate wave. One of these units was the Irish Brigade. "About 5 p.m. received orders to march by the left flank, which we did, preceded by the First Brigade. Both brigades advanced in line of battle through a wheat-field into a wood, in which was a considerable quantity of very large rocks, behind which they poured into us a brisk fire while advancing. We, however, drove them a considerable distance, and sent a great many prisoners to the rear. After being, I should think, about three-quarters of an hour engaged, the troops on our left had retired, and the enemy pressing hard on that point, on going to the right of brigade I found the enemy forming line faced to our right along the edge of the wood. Finding myself in this very disagreeable position, I ordered the brigade to fall back, firing. We here encountered a most terrific fire, and narrowly escaped being captured. We, however, got out, reformed the brigade, and joined the division near the Second Division hospital. It was now after nightfall, and, soon after, we were moved to the front, and slept on our arms all night."
