Harry admired the daring of his two leaders, and at the same time he trembled with apprehension. They had split their force, already far smaller, in the face of the foe. Suppose that foe, with his army of splendid fighters, should come suddenly from his intrenchments and attack either division. Surely the Northern scouts and spies were in the thickets. So great a movement as this could not escape their attention. It would be impossible for a large army to pass on that journey of many miles around Hooker and not one of the hundred thousand men he had in the Wilderness bring him a word of it. They might be discovered by one of the balloons, and Harry strained his eyes toward the far Rappahannock. He saw a black speck floating in the sky, which he thought to be one of the balloons, and he felt a little dread, but in a moment he realized that Jackson's army was as completely hidden by the Wilderness from any such possible observer as if a blanket lay over it. Then he dismissed all thoughts of balloons and rode on in silence beside Dalton. Now he listened to the roar behind them. It had the violence of a great battle, but he noticed that the sounds neither advanced nor retreated. He smiled a little. Lee was still amusing Hooker, but it was a grim amusement. A long time passed. Although the army could not move fast in the Wilderness, its march was steady. The roar of Lee's attack had become subdued, but Harry knew that the effect was due only to distance. His trained ear told him that the demonstration in Hooker's front, instead of decreasing, had increased in vigor. It was assuming the proportions of a real battle, and with thickets and forests to obscure sight, Hooker might well believe that the whole Southern army was yet in front of him. The onward march had become rhythmic now. It was to Harry like the regular throbbing of a pulse. The tread of many men, the beat of horses' hoofs, and the clanking of guns melted into one musical note. The sun crept slowly up, gilding thickets and forests with pure gold. The sky was still an unbroken blue, save for the little white clouds that floated in its bosom. The breeze of that May morning was wonderfully crisp and fresh. It came tingling with life to the thousands, so many of whom were about to die. It seemed to Harry as they went on through the thickets of the Wilderness that the Union scouts would never discover them, but Northern troops on an open eminence of Hazel Grove had seen a long column moving away through the thickets and made report of it to the Northern generals. But these leaders did not understand it. They had not grasped the great daring of Jackson's march.
