The word was now passed down the line that perfect silence was to be observed, and that they were to move forward in column, the ranks closing up as much as possible so as not to lose touch of each other. With heads bent down, and blankets wrapped round them as cloaks, the cavalry rode off through the pouring rain. The thunder was clashing overhead, and the flashes of the lightning enabled them to keep their places in close column. They went at a rapid trot, and even those who were ready to charge a body of the enemy, however numerous, without a moment's hesitation, experienced a feeling of nervousness as they rode on in the darkness through the thick forest on their unknown errand. That they were going northward they knew, and knew also, after a short time, that they must be entering the lines of the enemy. They saw no signs of watch-fires, for these would long since have been quenched by the downpour. After half an hour's brisk riding all knew by the sharp sound of the beat of the horses' hoofs that they had left the soft track through the forest and were now upon a regular road.

"Thank goodness for that!" Vincent said in a low tone to his next neighbor. "I don't mind a brush with the enemy, but I own I don't like the idea that at any moment my brains may be knocked out by the branch of a tree."

"I quite agree with you," the other replied; "and I fancy every man felt the same."

There was no doubt as to this. Hitherto no sound had been heard save the jingling of accouterments and the dull heavy sound of the horses' tread; but now there could be heard mingled with these the buzz of voices, and occasionally a low laugh. They were so accustomed to wet that the soaking scarce inconvenienced them. They were out of the forest now, and felt sure of their guide; and as to the enemy, they only longed to discover them.

For another hour the rapid advance continued, and all felt sure that they must now have penetrated through the enemy's lines and be well in his rear. At last they heard a challenge of sentry. Then Stuart's voice shouted, "Charge!" and at full gallop they rode into the village at Catlet's Station on the Orange and Alexandria railroad, where General Pope had his headquarters. Another minute and they were in the midst of the enemy's camp, where the wildest confusion reigned. The Federal officers rushed from their tents and made off in the darkness; but the soldiers, who were lying on the line of railroad, leaped to their feet and opened a heavy fire upon their invisible foes. Against this the cavalry, broken up in the camp, with its tents, its animals, and its piles of baggage, could do little, for it was impossible to form them up in the broken and unknown ground.

The quarters of Pope were soon discovered; he himself had escaped, leaving his coat and hat behind. Many of his officers were captured, and in his quarters were found a box of official papers which were invaluable, as among them were copies of his letters asking for reinforcements, lists giving the strength and position of his troops, and other particulars of the greatest value to the Confederates. No time was lost, as the firing would set the whole Federal army on the alert, and they might find their retreat cut off. Therefore placing their prisoners in the center, and taking the box of papers with them, the cavalry were called off from the camp, and without delay started on their return ride.

They did not take the road by which they had come, but made a long detour, and just as daylight was breaking re-entered the Confederate lines without having encountered a foe from the time of their leaving Catlet's Station. Short as their stay in the camp had been, few of the men had returned empty handed. The Northern army was supplied with an abundance of excellent food of all descriptions, forming the strongest possible contrast to the insufficient rations upon which the Confederate troops existed, and the troopers had helped themselves to whatever they could lay hands upon in the darkness and confusion.

Some rode in with a ham slung on each side of their saddle, others had secured a bottle or two of wine or spirits. Some had been fortunate enough to lay hands on some tins of coffee or a canister of tea, luxuries which for months had been unknown to them save when they were captured from the enemy. The only article captured of no possible utility was General Pope's coat, which was sent to Richmond, where it was hung up for public inspection; a wag sticking up a paper beside it, "This is the coat in which General Pope was going to ride in triumph into Richmond. The coat is here, but the general has not yet arrived."

The Confederates had lost but two or three men from the fire of the Federal infantry, and they were in high spirits at the success of their raid. No sooner had General Lee informed himself of the contents of the papers and the position of the enemy's forces than he determined to strike a heavy blow at him; and General Jackson, who had been sharply engaged with the enemy near Warrenton, was ordered to make a long detour, to cross the Blue Ridge mountains through Thoroughfare Gap, to fall upon Pope's rear and cut his communications with Washington, and if possible to destroy the vast depot of stores collected at Manassas.

The cavalry, under Stuart, were to accompany him. The march would be a tremendous one, the danger of thus venturing into the heart of the enemy's country immense, but the results of such an expedition would, if successful, be great; for Lee himself was to advance with his army on Pope's flank, and there was therefore a possibility of the utter defeat of that general before he could be joined by the army marching to reinforce him from Fredericksburg.
