"Shut up, you bird of ill omen, you raven, you," said Happy Tom. "Everything is going to happen for the best, we are going to win the victory, and we three are going to come out of the battle all right." St. Clair did not answer him. His was a serious nature and he foresaw a great struggle which would waver long in doubt. Harry had lain down on his blanket and was seeking sleep again. "Stop talking," he said to the other two. "We've got to go to sleep if it's only for the sake of our nerves. We must be fresh and steady when we go into the battle in the morning." "I suppose you are right," said Happy Tom, "but I find this overtaking slumber a long chase. Maybe you can form a habit of sleeping well before big battles, but I haven't had the chance to do so yet." Harry did fall asleep after a while, but he awoke before dawn to find that there was already bustle and movement in the army about him. Fires were lighted further back, and an early but plentiful breakfast was cooked. All were up and ready when the sun rose over the Virginia fields. "Another hot day," said Happy Tom. "See, the sun is as red as fire! And look how it burns on the water there." "Yes, hot it will be," Harry said to himself. They had eaten their breakfast and lay once more among the trees. Harry searched with his eyes the bushes and thickets on the other side for their riflemen, but most of them were still invisible in the day. Then the Southern brigades were ordered to lie down, but after they lay there some time Harry felt that the film of dust on the edge of the wind was growing stronger, and presently they saw a great cloud of it rising above hills and trees and moving toward them. "They're coming," said St. Clair. "In less than a half hour they'll be at the ford." "But I doubt if they know what is waiting for them," said Harry. The cloud of dust rapidly came nearer, and now they heard the beat of horses' feet and the clank of artillery. Harry began to breathe hard, and he and the other young officers walked up and down the lines of their company. All the Invincibles clearly saw that great plume of dust, and heard the ominous sounds that came with it. It was very near now, but suddenly the fringe of forest on the far side of the river burst into flame. The hidden riflemen had opened fire and were burning the front of the advancing army. But the Northern men came steadily on, rousing the riflemen out of the bushes, and then they appeared among the trees on the north side of Bull Run--a New York brigade led by Tyler. The moment their faces showed there was a tremendous discharge from the Southern batteries masked in the wood. The crash was appalling, and Harry shut his eyes for a moment, in horror, as he saw the entire front rank of the Northern force go down. Then the Southern sharpshooters in hundreds, who lined the water's edge, opened with the rifle, and a storm of lead crashed into the ranks of the hapless New Yorkers.
