The poor fellows gallantly sprang through it upon their assailants, and were in a moment fighting in the woods. Not half of this noble band ever came back. The rebels, taking this as a signal for the commencement of the action, now bestirred themselves in force, and fired a terrific volley along their whole front. Only the sheeted flash showed itself from those frowning forests; the foe still clung to cover; but the hail of bullets rattled against the Union lines, and many brave souls were sent into eternity by that first fiery revelation of the enemy’s strength. The reply was instant and extended. In a second both ends of the field were clouded with smoke, the day’s skirmishing was over, and the contest that was to rage so hotly for an hour had commenced its fury. The battle on the part of the Federals was fought heroically, and in a true sacrificial spirit. The enemy was in force in front; he began to creep down the treacherous sides of the enclosure; his sharpshooters climbed the trees everywhere, picking out the stateliest and most gallant forms for the death they so unerringly dealt. The lines thus received a scathing fire from the front, from above, and a cross-fire at angles right and left. All they could do in reply was to aim steadily and swiftly at the places whence the loudest yells and deadliest volleys proceeded. But the men dropped everywhere, and were borne by dozens to the gory skiffs below. On the right the Massachusetts men were more than decimated by the regular, unavoidable shower of bullets. But against the left, where Wistar commanded, the rebels, confident of their force and the effect of their deadly fire in front, began to make venturesome charges, each one repelled by the gallant fire of the Californians, but each one getting nearer the Federal lines than the last. On the fourth charge they actually flanked the left, and sprang forth, savage and eager, from the thicket beyond the ravine. Down this they were about to plunge. “Hold!” cried Wistar to his men; “not a man of you must fire;” and he dashed at the piece of one; “wait till they reach the bottom of the ravine; then we’ll have them.” So they charged down the hill, only to meet the most effective volley fired on the Union side during that day. When the smoke rose their front ranks lay fallen in the hollow of the valley of death, and the rear had broken and fled in disorder through the forest.
