At this time Quimby’s regiment occupied another ridge to the left, overlooking the same field, fiercely engaged. Colonel Keyes, from Tyler’s division, had formed in line with Sherman’s brigade, and came into conflict on its right with the enemy’s cavalry and infantry, which he drove back. The further march of the brigade was arrested by a severe fire of artillery and infantry, sheltered by Robinson’s house, standing on the heights above the road leading to Bull Run. The charge was here ordered, and the Second Maine and Third Connecticut regiments pressed forward to the top of the hill, reached the buildings which were held by the enemy, drove them out, and for a moment had them in possession. At this point, finding the brigade under the fire of a strong force behind breastworks, the order was given to march by the left flank, with a view to turn the battery which the enemy had placed on the hill below the point at which the Warrenton turnpike crosses Bull Run. The march was conducted for a considerable distance below the Stone Bridge, causing the enemy to retire, and giving Captain Alexander an opportunity to pass the bridge, cut out the abatis which had been placed there, and prepare the way for Schenck’s brigade and the two batteries to pass over. Before this movement could be made on the enemy’s battery, it was placed in a new position; but Colonel Keyes carried his brigade, by a flank movement, around the base of the hill, and was on the point of ascending it in time to get at the battery, when he discovered that the troops were on the retreat, and that, unless a rapid movement to the rear was made, he would be cut off. At this moment, the abatis near the Stone Bridge had been cleared away by Captain Alexander, of the engineers, and Schenck’s brigade (the third of Tyler’s division) was about to pass over and join Keyes. But one rash movement had decided the day—that movement the last change of position given to Griffin’s battery, throwing it helpless into a murderous fire, which no protecting force could encounter. When the Zouaves broke on that fatal hill, the Union cause for that day wavered. When hordes of fresh troops poured in upon the Union battalions, beating back as brave regiments as ever trod the battle-field, one after another, overwhelming them with numbers, and driving them headlong into utter confusion, the battle was lost; and after this any description of it must be wild and turbulent as the scene itself—in no other way can a true picture of the tumultuous fighting and more tumultuous retreat be truly given. THE CLIMAX AND THE RETREAT.
