"Ah! that no one can say. The first is sure enough and less dangerous, if the commander is not certain of his men, because you notice that we felt excellent and confident all day, so long as we were marching forward and pushing the enemy from our path. The trial in battle is to be kept standing under fire, not sure where your enemy is; and then you noticed that our own guns behind us, sending shot and shells over us, were just as trying as the rebels'. Only soldiers of the very first class can be depended on in the Napoleon tactics. We are not soldiers of the first class; and you may be sure McDowell, who was many years in Europe, and who is a trained officer, will make use of the manoeuvres best calculated to bring out whatever there is in his men. As a matter of opinion, I should say that, in view of the miserable affair on the right yesterday, he will strike out for Sudley Springs, where we shall have the rebels just as you would have me if you were at my side, held my left arm behind me, ready to break my back with your knee planted in it." Jack was sergeant of the guard that night, and it was in the group of sentries awaiting their relief every two hours, re-enforced by his tent-mates of Company K, that these learned dissertations on war were carried on. It was a never to be forgotten Saturday night to millions yet living. In Washington the President and his Cabinet sat far into the morning hours receiving the dispatches from the weary and disappointed chief--for, if Tyler had not made his miserable attempt to reach Manassas, the battle would have been fought that vital Saturday, and the result would have been another story in history. As the morning broke, red and murky, the army was up and in line, but without the usual noisy signals. The artillery-horses began to move first wherever it was possible. The heavy guns were pushed forward on the sward, to prevent the loud metallic clangor that penetrated the still air like clashing anvils. By half after six, the advance brigade, the Caribees in their old place, were within gunshot of the stone bridge. "Ah ha, Jack! It is the Napoleonic plan!" Barney cried, as the artillery took places in front of the masses lying on the ground. "Wait," Jack cried, owlishly. "The battle isn't fought always where the guns are loudest." But the guns were now loud and quick. The rebels, behind a thick screen of trees, took up the challenge, and every sound was drowned in the roar of the artillery. A few far in the rear were wounded--those nearest the rebels were in the least danger, whether because the guns could not be sufficiently depressed, or because the gunners were poor hands, couldn't be determined. A breathless suspense, an insatiate craving to see, to move, to fly forward, or do anything, devoured the prostrate ranks. The firing had gone on two hours or more, which seemed only so many minutes, when to the group near General Tyler a courier, panting and dusty, rode in great excitement.
