"It's the Yankees who are being made into foreigners," said Lieutenant-Colonel St. Hilaire. "The gallant Southern people, of course, remain what they are."
"They're going," said Harry. "They've seen enough of us."
The distant troop disappeared over the crest of the hill. Harry had noticed that Shepard led the way as if he were the ruling spirit, but he did not consider it necessary to say anything to the others about him. The trumpet blew and Sherburne's force, mounting, rode away from the cove. Harry cast one regretful glance back at the splendid fire which still glowed there, and then resigned himself to the cold and rain.
They did not stop again until far in the night. The rain ceased, but the whole earth was sodden and the trees on the low ridge, on which Sherburne camped, dripped with water. Spies might be all around them, but for the sake of physical comfort and the courage that he knew would come with it, he ordered another big fire built. Vigilant riflemen took turns in beating up the forests and fields for possible enemies, but the young officers once more enjoyed the luxury of the fire. Their clothing was dried thoroughly, and their tough and sinewy frames recovered all their strength and elasticity.
"To enjoy being dry it is well to have been wet," said Dalton sententiously.
"That's just like you, you old Presbyterian," said Happy Tom. "I suppose you'll argue next that you can't enjoy Heaven unless you've first burned in the other place for a thousand years."
"There may be something in that," said Dalton gravely, "although the test, of course, would be an extremely severe one."
"I know which way you're headed, George."
"Then tell me, because I don't know myself."
"As soon as this war is over you'll enter the ministry, and no sin will get by you, not even those nice little ones that all of us like to forgive."
"Maybe you're right, Happy, and if I do go into the ministry I shall at once begin long and earnest preparation for the task which would necessarily be the most difficult of my life."
"And may I make so bold as to inquire what it is, George?"
"Your conversion, Happy."
Langdon grinned.
"But why do you want to convert me, George? I'm perfectly happy as I am."
"For your own well being, Tom. Your happiness is nothing to me, but I want to make you good."
Both laughed the easy laugh of youth, but Harry looked long at Dalton. He thought that he detected in him much of the spirit of Stonewall Jackson, and that here was one who had in him the makings of a great minister. The thought lingered with him.
St. Clair was carefully smoothing out his uniform and brushing from it the least particle of mud. His first preoccupation always asserted itself at the earliest opportunity, and in a very short time he was the neatest looking man in the entire force. Harry, although he often jested with him about it, secretly admired this characteristic of St. Clair's.
"You boys sleep while you can," said Sherburne, "because we can't afford to linger in this region. Our safety lies in rapid marching, giving the enemy no chance to gather a large force and trap us. Make the best of your time because we're up and away an hour after midnight."
The young officers were asleep within ten minutes, but the vigilant riflemen patrolled the country in a wide circuit about them. Sherburne himself, although worn by hard riding, slept but little. Anxiety kept his eyes open. He knew that his task to find a passage for the army across the swollen Potomac was of the utmost importance and he meant to achieve it. He understood to the full the dangerous position in which the chief army of the Confederacy stood. His own force might be attacked at any moment by overwhelming numbers and be cut off and destroyed or captured, but he also knew the quality of the men he led, and he believed they were equal to any task.
As he sat by the fire thinking somberly, a figure in the brush no great distance away was watching him. Shepard, the spy, in the darkness had passed with ease between the sentinels, using the skill of an Indian in stalking or approaching, and now, lying well hidden, almost flat upon his stomach, he surveyed the camp. He looked at Sherburne, sitting on a log and brooding, and he made out Harry's figure wrapped in a blanket and lying with his feet to the fire.
Shepard's mind was powerfully affected. An intense patriot, something remote and solitary in his nature had caused him to undertake this most dangerous of all trades, to which he brought an intellectual power and comprehension that few spies possess. As Harry had discovered long since, he was a most uncommon man.
Now Shepard as he gazed at this little group felt no hatred for them or their men. He had devoted his life to the task of keeping the Union intact. His work must be carried out in obscure ways. He could never hope for material reward, and if he perished it would be in some out-of-the-way corner, perhaps at the end of a rope, a man known to so few that there would be none to forget him. And yet his patriotism was so great and of such a fine quality that he viewed his enemies around the fire as his brethren. He felt confident that the armies of the North would bring them back into the Union, and when that occurred they must come as Americans on an equal footing with other Americans. They could not be in the Union and not of it.
But Shepard's feeling for his official enemies would not keep him from acting against them with all the skill, courage and daring that he possessed in such supreme measure. He knew that it was Sherburne's task to open a way for the Army of Northern Virginia to the Potomac and to find a ford, or, in cooperation with some other force, to build a bridge. It was for him to defeat the plan if he could.
While the rain all the day before had brought gloom to the hearts of Sherburne and his men it had filled his with joy, as he thought of the innumerable brooks and creeks that were pouring their swollen waters into the Potomac, already swollen too. He meant now to follow Sherburne's force, see what plan it would attempt, what point, perhaps, it would select for the bridge, and then bring the Union brigades in haste to defeat it.
It is said that men often feel when they are watched, although the watcher is invisible, but it was not so in Sherburne's case. He did not in the least suspect the presence of Shepard or of any foe, and the spy, after he had seen all he wished, withdrew, with the same stealth that had marked his coming.
An hour after midnight all were awakened and they rode away. The next day they reached the Potomac near Williamsport, where their pontoon bridge had been destroyed, and looked upon the wide stream of the Potomac, far too deep for fording.
"If General Lee is attacked on the banks of this river by greatly superior forces," said Sherburne, "he'll have no time to build bridges. If we didn't happen to be victorious our forces would have to scatter into the mountains, where they could be hunted down, man by man."
"But such a thing as that is unthinkable, sir," said Harry. "We may not win always, but here in the East we never lose. Remember Antietam and the river at our back."
"Right you are, Harry," said Sherburne more cheerfully. "The general will get us out of this, and here is where we must cross. The river may run down enough in two or three days to permit of fording. God grant that it will!"
"And so say I!" repeated Harry with emphasis.
"I mean to hold this place for our army," continued Sherburne.
"A reserved seat, so to speak."
"Yes, that's it. We must keep the country cleared until our main force comes up. It shouldn't be difficult. I haven't heard of any considerable body of Union troops between us and the river."
They made camp rapidly in a strong position, built their fires for cooking, set their horses to grazing and awaited what would come. It was a dry, clear night, and Harry, who had no duties, save to ride with a message at the vital moment, looked at once for his friends, the Invincibles.
St. Clair met him and held up a warning hand, while Happy touched his lip with his finger. Before the double injunction of silence and caution, Harry whispered:
"What's happened?"
"A tragedy," replied St. Clair.
"And a victory, too," said Happy Tom.
"I
