McClellan held a strong position at Harrison's Landing, where, if he accomplished nothing else, he was a standing menace to Richmond, so that Lee dared not withdraw his army from its defence. He wanted to be heavily reinforced, cross the James, and strike at Richmond's southern communications, just as Grant actually did two years later; and he was promised reinforcements from the troops of Burnside and Hunter, on the coast of North and South Carolina. Lee's anxiety was to get McClellan off from the peninsula, so that he could strike out toward Washington. He first sent a detachment to bombard McClellan's camp from the opposite side of the James; but McClellan crossed the river with a sufficient force and easily swept it out of the way. Then Lee sent Jackson to make a demonstration against Pope, holding the main body of his army ready to follow as soon as some erratic and energetic movements of Jackson had caused a sufficient alarm at Washington to determine the withdrawal of McClellan. The unwitting Halleck was all too swift to coöperate with his enemy, and had already determined upon that withdrawal. Burnside's troops, coming up on transports, were not even landed, but were forwarded up the Potomac and sent to Pope. McClellan marched his army to Fort Monroe, and there embarked it by divisions for the same destination.

MAJOR-GENERAL JOHN POPE.

Pope's intention was to push southward, strike Lee's western and northwestern communications, and cut them off from the Shenandoah Valley. He first ordered Banks (July 14) to push his whole cavalry force to Gordonsville, and destroy the railroads and bridges in that vicinity. But the cavalry commander, General Hatch, took with him infantry, artillery, and a wagon train, and consequently did not move at cavalry speed. Before he could get to Gordonsville, Jackson's advance reached it, and his movement was frustrated. He was relieved of his command, and it was given to Gen. John Buford, an able cavalry leader.

As soon as Jackson came in contact with Pope's advance, he called upon Lee for reinforcements, and promptly received them. On the 8th of August he crossed the Rapidan, and moved toward Culpeper. Pope, who had but recently taken the field in person, having remained in Washington till July 29th, attempted to concentrate the corps of Banks and Sigel at Culpeper. Banks arrived there promptly on the 8th; but Sigel sent a note from Sperryville in the afternoon, asking by what road he should march. "As there was but one road between those two points," says Pope, "and that a broad stone turnpike, I was at a loss to understand how General Sigel could entertain any doubt as to the road by which he should march." On the morning of the 9th Banks's corps went out alone to meet the enemy at Cedar Mountain. Banks had eight thousand men (Pope says he had supposed that corps numbered fourteen thousand), and attacked an enemy twice as strong. He first struck Jackson's right wing, and afterward furiously attacked the left, rolled up the flank, opened a fire in the rear, and threw Jackson's whole line into confusion. It was as if the two commanders had changed characters, and Banks had suddenly assumed the part that, according to the popular idea, Jackson was always supposed to play. If Sigel had only known what road to take, that might have been the last of Jackson. But Banks's force had become somewhat broken in its advance through the woods, and at the same time the Confederates were reinforced, so that Jackson was able to rally his men and check the movement. Banks in turn was forced back a short distance, where he took up a strong position.

Sigel's corps arrived in the evening, relieved Banks's corps, and made immediate preparations for a renewal of the fight in the morning. The dead were buried, the wounded carried forth, and through the night trains were moving and everything being put in readiness, but at daylight it was discovered that the enemy had fallen back two miles to a new position. Partly because of the strong position held by each, and partly because of the very hot weather, there was little further disposition to renew the fight, and two days later Jackson fell still further back to Gordonsville. In this action, which for the numbers engaged was one of the fiercest and most rapid of the war, the Confederates lost about thirteen hundred men and the National army about eighteen hundred. "Besides which," says General Pope, "fully one thousand men straggled back to Culpeper Court House and beyond, and never entirely returned to their commands." On the other hand, the cavalry under Buford and Bayard pursued the enemy and captured many stragglers. The Confederate Gen. Charles S. Winder was struck by a shell and killed while leading his division.

POPE'S BAGGAGE-TRAIN IN THE MUD. VIEW IN CULPEPER.

Immediately after this action the cavalry resumed its former position along the Rapidan from Raccoon Ford to the mountains. On the 14th of August General Pope was reinforced by eight thousand men under General Reno, whereupon he pushed his whole force forward toward the Rapidan, and took up a position with his right on Robertson's River, his centre on the slopes of Cedar Mountain and his left near Raccoon Ford. From this point he sent out cavalry expeditions to destroy the enemy's communications with Richmond, and one of these captured General Stuart's adjutant, with a letter from Lee to General Stuart, dated August 15th, which to a large extent revealed Lee's plans. The incident that resulted in this important capture is thus related by Stuart's biographer, Major H. B. McClellan: "Stuart reached Verdiersville on the evening of the 17th, and hearing nothing from Fitz Lee, sent his adjutant, Major Norman R. Fitz Hugh, to meet him and ascertain his position. A body of the enemy's cavalry had, however, started on a reconnoissance on the previous day, and in the darkness of the night Major Fitz Hugh rode into this party and was captured. On his person was found an autograph letter from the commanding general to Stuart which disclosed to General Pope the design of turning his left flank. The fact that Fitz Hugh did not return aroused no apprehension, and Stuart and his staff imprudently passed the night on the porch of an old house on the Plank Road. At daybreak he was aroused by the noise of approaching horsemen, and sending Mosby and Gibson, two of his aides, to ascertain who was coming, he himself walked out to the front gate, bareheaded, to greet Fitz Lee, as he supposed. The result did not justify his expectations. In another instant pistol shots were heard, and Mosby and Gibson were seen running back, pursued by a party of the enemy. Stuart, Von Borcke, and Dabney had their horses inside of the inclosure of the yard. Von Borcke gained the gate and the road, and escaped unhurt after a long and hard run. Stuart and Dabney were compelled to leap the yard fence and take across the fields to the nearest woods. They were pursued but a short distance. Returning to a post of observation, Stuart saw the enemy depart in triumph with his hat and cloak, which he had been compelled to leave on the porch where he had slept. He bore this mortification with good nature. In a letter of about that date he writes: 'I am greeted on all sides with congratulations and "Where's your hat?" I intend to make the Yankees pay for that hat.' And Pope did cancel the debt a few nights afterward at Catlett's Station."

The captured despatch revealed to Pope the fact that Lee intended to fall upon him with his entire army and crush him before he could be reinforced from the Army of the Potomac. Pope says: "I held on to my position, thus far to the front, for the purpose of affording all time possible for the arrival of the Army of the Potomac at Acquia and Alexandria, and to embarrass and delay the movements of the enemy as far as practicable. On the 18th of August it became apparent to me that this advanced position, with the small force under my command, was no longer tenable in the face of the overwhelming forces of the enemy. I determined, accordingly, to withdraw behind the Rappahannock with all speed, and, as I had been instructed, to defend, as far as practicable, the line of that river. I directed Major-General Reno to send back his trains, on the morning of the 18th, by the way of Stevensburg, to Kelly's or Burnett's Ford, and, as soon as the trains had gotten several hours in advance, to follow them with his whole corps, and take post behind the Rappahannock, leaving all his cavalry in the neighborhood of Raccoon Ford to cover this movement. General Banks's corps, which had been ordered, on the 12th, to take position at Culpeper Court House, I directed, with its trains preceding it, to cross the Rappahannock at the point where the Orange and Alexandria railroad crosses that river. General McDowell's train was ordered to pursue the same route, while the train of General Sigel was directed through Jefferson, to cross the Rappahannock at Warrenton Sulphur Springs. So soon as these trains had been sufficiently advanced, McDowell's corps was directed to take the route from Culpeper to Rappahannock Ford, whilst General Sigel, who was on the right and front, was instructed to follow the movements of his train to Sulphur Springs. These movements were executed during the day and night of the 18th, and the day of the 19th, by which time the whole army, with its trains, had safely recrossed the Rappahannock and was posted behind that stream, with its left at Kelly's Ford and its right about three miles above Rappahannock Station." The Confederates followed rapidly, and on the 20th confronted Pope at Kelly's Ford, but with the river between. For two days they made strenuous efforts to cross, but a powerful artillery fire, which was kept up continuously for seven or eight miles along the river, made any crossing in force impossible. Lee therefore sent Jackson to make a flank march westward along that stream, cross it at Sulphur Springs, and come down upon Pope's right. But when Jackson arrived at the crossing, he found a heavy force occupying Sulphur Springs and ready to meet him. Meanwhile Gen. James E. B. Stuart, with fifteen hundred cavalrymen, in the dark and stormy night of August 22d, had ridden around to the rear of Pope's position, to cut the railroad. He struck Pope's headquarters at Catlett's Station, captured three hundred prisoners and all the personal baggage and papers of the commander, and got back in safety. These papers informed Lee of Pope's plans and dispositions.

Jackson, being thwarted at Sulphur Springs, moved still farther up the south bank of the Rappahannock, crossed the headwaters, and turned Pope's right. He passed through Thoroughfare Gap in the Bull Run Mountains on the 26th, destroyed Bristoe Station on the Orange and Alexandria railroad, and sent out Stuart to Manassas Junction, where prisoners were taken and a large amount of commissary stores fell into his hands.
