Chapter III. Beside the River

Dick was on duty early in the morning when he saw a horseman coming at a gallop toward the Rapidan. The man was in civilian clothing, but his figure seemed familiar. The boy raised his glasses, and he saw at once that it was Shepard. He saw, too, that he was urging his horse to its utmost speed.

The boy's heart suddenly began to throb, and there was a cold, prickling sensation at the roots of his hair. Shepard had made an extraordinary impression upon him and he did not believe that the man would be coming at such a pace unless he came with great news.

He saw Shepard stop, give the pass word to the pickets, then gallop on, ford the river and come straight toward the heart of the army. Dick ran forward and met him.

"What is it?" he cried.

"General Pope's tent! Where it is! I can't wait a minute."

Dick pointed toward a big marquee, standing in an open space, and Shepard leaping from his horse and abandoning it entirely, ran toward the marquee. A word or two to the sentinels, and he disappeared inside.

Dick, devoured with curiosity and anxiety, went to Colonel Winchester with the story of what he had seen.

"Look! Look at the mountain!" he exclaimed.

"I see it," said Warner. "I saw it there yesterday, too, in exactly the same place."

"So did I, but there's something behind it. Lee and Jackson are there with sixty or eighty thousand men! The whole Southern army is only six or seven miles away."

Even Warner's face changed.

"How do you know this?" he asked.

"A spy has seen their army. They say he is a man whose reports are never false. At any rate orders have already been issued for us to retreat and I hear that we're going back until we reach the Rappahannock, behind which we will camp."

Dick knew very well now that it was Shepard who brought the news, and Pennington's report about the retreat was also soon verified. The whole army was soon in motion and a feeling of depression replaced the optimism of the night before. The advance had been turned into a retreat. Were they to go back and forth in this manner forever? But Colonel Winchester spoke hopefully to his young aides and said that the retreat was right.

"We're drawing out of a
