The words were abrupt, sharp, admitting of no question or delay, and the four fairly ran. Harry and his comrades lay down at the edge of the cliff and swept the valley with their glasses. The great guns were still firing at intervals of about a minute. The gunners could not see the Southern troops drawn back behind the ridges, but Harry believed that they might be guided by signals from men on opposite slopes. But if signalmen were there they were hidden by the forest even from his glasses. The smoke from the cannon was gathering heavily in the narrow valley, so heavily that it began to obscure what was passing there in the Northern army. But the four, remembering the injunction of Jackson, a man who must be obeyed to the last and minutest detail, still sought to pierce through the smoke both with the naked eye and with glasses. As a rift appeared Harry saw a moving mass of men in blue. It was a great body of troops and the sun shining through the rift glittered over bayonets and rifle barrels. They were marching straight toward a slope which led at a rather easy grade up the side of the mountain. “They're not waiting to be attacked! They're attacking!” cried Harry, springing to his feet and running to the point where he knew Jackson stood. Jackson received his news, looked for himself, and then began to push on the troops. A shout arose as the army pressed forward to meet the enemy who were coming so boldly. “We ought to beat 'em, as we have the advantage of the heights,” exclaimed Sherburne, who was now on foot. But the advantage was the other way. Those were staunch troops who were advancing, men of Ohio and West Virginia, and while they were yet on the lower slopes their cannon, firing over their heads, swept the crest with shot and shell. The eager Southern youths, as invariably happens with those firing downward, shot too high. The Northern regiments now opening with their rifles and taking better aim came on in splendid order. “What a magnificent charge!” Harry heard Sherburne exclaim. The rifles by thousands were at work, and the unceasing crash sent echoes far through the mountains. The Southerners at the edge of the cliff were cut down by the fire of their enemy from below. Their loss was now far greater than that of the North, and their officers sought to draw them back from the verge, to a ridge where they could receive the charge, just as it reached the crest and pour into them their full fire. The eager young regiment from Georgia refused to obey. “Have we come all these hundreds of miles from Georgia to run before Yankees?” they cried, and stood there pulling trigger at the enemy, while their own men fell fast before the bitter Northern hail.
