"And you cannot. It was never possible. Oh, I know that you've won great victories against odds! You've done better than anybody could have expected, but you had genius to help you, while we were led by mediocrity in the saddle. But you have reached your zenith. Mark how the Union veterans fought to-day. They're as brave and resolute as you are, and we have the position and the men. You'll never get beyond Gettysburg. Your invasion is over. Hereafter you fight always on the defensive."
Harry was startled by his emphasis. The man spoke like an inspired prophet of old. His eyes sparkled like coals of fire in the dark, tanned face. The boy had never before seen him show so much emotion, and his heart sank at the appalling prophecy. Then his courage came back.
"You predict as you hope, Mr. Shepard," he said.
Shepard laughed a little, though not with mirth, and said:
"It is well that it should be settled here. There will be death on a greater scale than any the war has yet seen, but it will have to come sooner or later, and why not at Gettysburg? Good-bye, I go back to the heights. May we both be alive to-morrow night to see which is right."
"The wish is mine, too," said Harry sincerely.
Shepard turned away and disappeared in the darkness. Harry rejoined Dalton who was on the other side of the spring, and the two returned to Seminary Ridge, where they walked among sleeping thousands. They found their way to their comrades of the staff, and their physical powers collapsing at last they fell on the ground where they soon sank into a heavy sleep. The great silence came again. Sentinels walked back and forth along the hostile lines, but they made no noise. There was little moving of brigades or cannon now. The town itself became a town of phantom houses in the moonlight, nearly all of them still and deserted. On all the slopes of the hostile ridges lay the sleeping soldiers, and on the rocks and fields between lay the dead in thousands. But from the crest of Little Round Top, the precious hill so hardly won, the Union officers watched all through the night, and, now and then, they went through the batteries for which they were sure they were going to have great use.
Harry and Dalton awoke at the same time. Another day, hot and burning, had come, and the two armies once more looked across the valley at each other. Harry soon heard the booming of cannon off to his right, where Ewell's corps stood. It came from the Northern guns and for a long time those of the South did not answer. But after a while Harry's practiced ear detected the reply. The hostile wings facing each other were engaged in a fierce battle. He saw the flash of the guns and the rising smoke, but the center of the Army of Northern Virginia and the other wing did not yet move. He looked questioningly at Dalton and Dalton looked questioningly at him.
They expected every instant that the combat would spread along the entire front, but it did not. For several hours they listened to the thunder of the guns on the left, and then they knew by the movement of the sound that the Southern wing had been driven back, not far it is true, but still it had been compelled to yield, and again Harry's heart sank.
But it rose once more when he concluded that Lee must be massing his forces in the center. The left wing had been allowed to fight against overwhelming numbers in order that the rest of the army might be left free to strike a crushing blow.
