Shepard's heart for the first time beat a little faster. He had felt as much as any general the Northern defeats and humiliations in the east, but, like officers and soldiers, he was not crushed by them. He even felt that the tide might be about to turn. Lee, invading the North, would find before him many of the difficulties which had faced the Northern generals attacking the South. Shepard, a man of supreme courage, resolved that he would spare no effort in the service to which he had devoted himself. He spent fully four hours in the thickets, and then, feeling that he had achieved his task, bore away toward the river. Taking off his coat and belt with pistols in it, and fastening them about his neck, he swam with bold strokes to the other side of the stream. However, had anyone been on the watch at that very point, it was not likely that he would have been seen. It was the approach of dawn and heavy mists were rising on the Rappahannock, as they had risen at Fredericksburg and Chancellorsville. Shepard gave the countersign to the pickets and was shown at once to General Pleasanton, an alert, vigorous man, who was awaiting him. His report was satisfactory, because the cavalry general smiled and began to send quick orders to his leaders of divisions. But the peace in Stuart's command was not broken that night. No one had seen the figure of the spy sliding through the thickets, and Harry and his comrades in the Inn of the Greenwood Tree were very warm and snug in their blankets. As day came he yawned, stretched, closed his eyes again, thinking that he might have another precious fifteen minutes, but, recalling his resolution, sprang to his feet and began to rub his eyes clear. He had slept fully dressed, like all the rest, and he intended to go down to a brook in a few minutes and bathe his face. But he first gave Sherburne a malicious shove with his foot and bade him wake up, telling him that it was too late for an alert cavalry captain to be sleeping. Then Sherburne also yawned, stretched, and stood up, rubbing his eyes. The others about them rose too, and everybody felt chilled by the river fog, which was uncommonly heavy. "Breakfast for me," said Sherburne. "Not just now, I think," said Harry. "Listen! Aren't those rifle shots?" A patter, patter, distant but clear in the morning, came from a point down the stream. "You're right!" exclaimed Sherburne in alarm. "It's on our side of the river and it's increasing fast! As sure as we live, the enemy has crossed and attacked!" They were not left in doubt. The pickets, running in, told them that a heavy force of Northern cavalry was across the Rappahannock and was charging with vigor. In fact, two of the divisions had passed the fords unseen in the fog and were now rushing Stuart's camp.
