The horse stretched out his neck, and the road flew behind him, his body working like a mighty machine perfectly attuned, even to its minutest part. Harry's words had met a true response. He heard a cry on the cross road, and the bobbing heads came forward much faster. Either they had seen him or they had heard the swift beat of his horse's hoofs. Loud shouts arose, but he saw the uniforms of the men, and he knew that they belonged to the Northern army.
He went past the junction of the roads, as if he were flying, but he was not a bit too soon, as he heard the crack of rifles, and bullets struck in the earth behind him. He knew that they would follow, hang on persistently, but he had supreme confidence in the speed and strength of his horse, and youth rode triumphant. It was youth more than anything else that made him raise himself a little in his saddle, look back to his pursuers and fling to them a long, taunting cry, just as Henry Ware more than once had taunted his Indian pursuers before disappearing in a flight that their swiftest warriors could not match.
But the little band of Union troopers clung to the chase. They too had good horses, and they knew that the man before them was a Southern messenger, and in those hot July days of 1863 all military messages carried on the roads north of the Potomac were important. The fate of an army or a nation might turn upon any one of them, and the lieutenant who led the little Union troop was aware of it. He was a man of intelligence and a consuming desire to overtake the lone horseman lay hold of him. He knew, as well as any general, that since Gettysburg the fate of the South was verily trembling in the balance, and the slightest weight somewhere might decide the scales. So he resolved to hang on through everything and the chances were in his favor. It was his own country. The Federal troops were everywhere, and any moment he might have aid in cutting off the fugitive.
When Harry eased his horse's flight he saw the troop, very distant but still pursuing, and he read the mind of the Union leader. He was saving his mounts, trailing merely, in the hope that Harry would exhaust his own horse, after which he and his men would come on at great speed.
Harry looked down at his horse and saw that he was heaving with his great effort. He knew that he had made a mistake in driving him so hard at first, and with the courage of which only a young veteran would have been capable he brought the animal almost to a walk, and resolutely kept him there, while the enemy gained. When they were almost within rifle shot he increased his speed again, but he did not seek for the present to increase his gain.
As long as their bullets could not reach him his horse should merely go stride for stride with theirs, and when the last stretch was reached, he would send forward the brave animal at his utmost speed. His were the true racing tactics drawn from his native state. He had no doubt of his ability to leave his pursuers far behind when the time came, but his true danger was from interference. He too knew that many Union cavalry troops were abroad, and he watched on either flank for them as he rode on. At the crest of every little hill he swept the whole country, but as yet he saw nothing but peaceful farmhouses.
The day was clear and bright, not so warm as its predecessors, and he calculated by the sun that he was going straight toward Lee. He knew that a great army always marched slowly, and he was able to reckon with accuracy just how far the Army of Northern Virginia had come since Gettysburg. He should reach it in the morning, with full information about the Potomac, and the best place for a crossing.
He arrived at the crest of a hill higher than the others, and saw the Union troop, about a quarter of a mile behind, stop beside a clump of tall trees. Their action surprised Harry, who had thought they would never quit as long as they could find his trail. To his further surprise he saw one of the men dismount and begin to climb the tallest of the trees. Then he brought his glasses into play.
He saw the climber go up, up, until he had reached the last bough that would support him. Then he drew some thing from his pocket which he unrolled and began to wave rapidly. It was a flag and through his powerful glasses Harry clearly saw the Stars and Stripes. It was evident that they were signaling, but when one signals one usually signals to somebody. His breath shortened for a moment. He believed that the man in the tree was talking with his flag about the fugitive. Where was the one to whom he was talking?
He looked to both left and right, searching the fields and the forests, and saw nothing. Then, as he was sweeping his glasses again in a half curve he caught a glimpse of something straight ahead that made the great pulse in his throat beat hard. About a mile in front of him another man in a tree was waving a flag and beneath the tree were horsemen.
