It was no time, however, to indulge in reflections on the irony of fortune. All through the afternoon, while the sharp-set Confederates were sweeping away the profits which the Northern sutlers had wrung from Northern soldiers, Stuart’s vigilant patrols sent in report on report of the Federal movements. From Warrenton heavy columns were hurrying over the great highroad to Gainesville, and from Warrenton Junction a large force of all arms was marching direct on Bristoe. There was news, too, from Lee. Despite the distance to be covered, and the proximity of the enemy, a trooper of the Black Horse, a regiment of young planters which now formed Jackson’s Escort, disguised as a countryman, made his way back from headquarters, and Jackson learned that Longstreet, who had started the previous evening, was following his own track by Orleans, Salem, and Thoroughfare Gap.[[14]] It was evident, then, that the whole Federal army was in motion northwards, and that Longstreet had crossed the Rappahannock. But Longstreet had many miles to march and Thoroughfare Gap to pass before he could lend assistance; and the movement of the enemy on Gainesville threatened to intervene between the widely separated wings of the Confederate army.
It was no difficult matter for Jackson to decide on the course to be adopted. There was but one thing to do, to retreat at once; and only one line of escape still open, the roads leading north and north-west from Manassas Junction. To remain at Manassas and await Lee’s arrival would have been to sacrifice his command. 20,000 men, even with the protection of intrenchments, could hardly hope to hold the whole Federal army at bay for two days; and it was always possible that Pope, blocking Thoroughfare Gap with a portion of his force, might delay Lee for even longer than two days. Nor did it recommend itself to Jackson as sound strategy to move south, attack the Federal column approaching Bristoe, and driving it from his path to escape past the rear of the column moving to Gainesville. The exact position of the Federal troops was far from clear. Large forces might be encountered near the Rappahannock, and part of McClellan’s army was known to be marching westward from Aquia Creek. Moreover, such a movement would have accentuated the separation of the Confederate wings, and a local success over a portion of the hostile army would have been but a poor substitute for the decisive victory which Lee hoped to win when his whole force was once more concentrated.
About three in the afternoon the thunder of artillery was heard from the direction of Bristoe. Ewell had sent a brigade along the railroad to support some cavalry on reconnaissance, and to destroy a bridge over Kettle Run. Hardly had the latter task been accomplished when a strong column of Federal infantry emerged from the forest and deployed for action. Hooker’s division of 5,500 men, belonging to McClellan’s army, had joined Pope on the same day that Jackson had crossed the Rappahannock, and had been dispatched northwards from Warrenton Junction as soon as the news came in that Manassas Junction had been captured. Hooker had been instructed to ascertain the strength of the enemy at Manassas, for Pope was still under the impression that the attack on his rear was nothing more than a repetition of the raid on Catlett’s Station. Striking the Confederate outposts at Kettle Run, he deployed his troops in three lines and pushed briskly forward. The batteries on both sides opened, and after a hot skirmish of an hour’s duration Ewell, who had orders not to risk an engagement with superior forces, found that his flanks were threatened. In accordance with his instructions he directed his three brigades to retire in succession across Broad Run. This difficult manœuvre was accomplished with trifling loss, and Hooker, ascertaining that Jackson’s whole corps, estimated at 30,000 men, was near at hand, advanced no further than the stream. Ewell fell back slowly to the Junction; and shortly after midnight the three Confederate divisions had disappeared into the darkness. The torch had already been set to the captured stores; warehouses, trains, camps, and hospitals were burning fiercely, and the dark figures of Stuart’s troopers, still urging on the work, passed to and fro amid the flames. Of the value of property destroyed it is difficult to arrive at an estimate. Jackson, in his official report, enumerates the various items with an unction which he must have inherited from some moss-trooping ancestor. Yet the actual quantity mattered little, for the stores could be readily replaced. But the effect of their destruction on the Federal operations was for the time being overwhelming. And of this destruction Pope himself was a witness. The fight with Ewell had just ceased, and the troops were going into bivouac, when the Commander-in-Chief, anxious to ascertain with his own eyes the extent of the danger to which he was exposed, reached Bristoe Station. There, while the explosion of the piles of shells resembled the noise of a great battle, from the ridge above Broad Run he saw the sky to the north-east lurid with the blaze of a vast conflagration; and there he learned for the first time that it was no mere raid of cavalry, but Stonewall Jackson, with his whole army corps, who stood between himself and Washington.
For the best part of three days the Union general had been completely mystified. Jackson had left Jefferson on the 25th. But although his march had been seen by the Federal signaller on the hills near Waterloo Bridge,[[15]] and the exact strength of his force had been reported, his destination had been unsuspected. When the column was last seen it was moving northward from Orleans, but the darkness had covered it, and the measure of prolonging the march to midnight bore good fruit. For the best part of two days Jackson had vanished from his enemy’s view, to be found by Pope himself at Manassas Junction.[[16]] Nevertheless, although working in the dark, the Federal commander, up to the moment he reached Bristoe Station, had acted with sound judgment. He had inferred from the reports of his signalmen that Jackson was marching to Front Royal on the Shenandoah; but in order to clear up the situation, on the 26th Sigel and McDowell were ordered to force the passage of the Rappahannock at Waterloo Bridge and the Sulphur Springs, and obtain information of the enemy’s movements. Reno, at the same time, was to cross below the railway bridge and make for Culpeper. The manœuvres, however, were not carried out as contemplated. Only McDowell advanced; and as Lee had replaced Longstreet, who marched to Orleans the same afternoon, by Anderson, but little was discovered.
It was evident, however, that the Confederates were trending steadily northwards, and on the night of the 26th Pope ordered his 80,000 Federals to concentrate in the neighbourhood of Warrenton. Reports had come in that hostile troops had passed through Salem, White Plains, and Thoroughfare Gap.[[17]] But it seemed improbable, both to Pope and McDowell, the second in command, that more was meant by this than a flank attack on Warrenton. McDowell expressed his opinion that a movement round the right wing in the direction of Alexandria was far too hazardous for the enemy to attempt. Pope appears to have acquiesced, and a line of battle near Warrenton, with a strong reserve at Greenwich, to the right rear, was then decided on. Franklin’s army corps from the Peninsula, instead of proceeding to Aquia Creek, was disembarking at Alexandria, and Halleck had been requested to push these 10,000 men forward with all speed to Gainesville. The Kanawha regiments had also reached Washington, and Pope was under the impression that these too would be sent to join him. He had therefore but little apprehension for his rear. The one error of judgment into which both Pope and McDowell had been betrayed was in not giving Lee due credit for audacity or Jackson for energy. That Lee would dare to divide his army they had never conceived; that Jackson would march fifty miles in two days and place his single corps astride their communications was an idea which had they thought of they would have instantly dismissed. Like the Austrian generals when they first confronted Napoleon, they might well have complained that their enemy broke every rule of the military art; and like all generals who believe that war is a mere matter of precedent, they found themselves egregiously deceived.
The capture of Manassas, to use Pope’s own words, rendered his position at Warrenton no longer tenable, and early on the 27th, the army, instead of concentrating on Warrenton, was ordered to move to Gainesville (from Gainesville it was easy to block Thoroughfare Gap); Buford’s cavalry brigade was thrown out towards White Plains to observe Longstreet, and Hooker was dispatched to clear up the situation at Manassas. This move, which was completed before nightfall, could hardly have been improved upon. The whole Federal army was now established on the direct line of communication between Jackson and Lee, and although Jackson might still escape, the Confederates had as yet gained no advantage beyond the destruction of Pope’s supplies. It seemed impossible that the two wings could combine east of the Bull Run Mountains. But on the evening of the 27th, after the conclusion of the engagement at Bristoe Station, Pope lost his head. The view he now took of the situation was absolutely erroneous. Ewell’s retreat before Hooker he interpreted as an easy victory, which fully compensated for the loss of his magazines. He imagined that Jackson had been surprised, and that no other course was open to him than to take refuge in the intrenchments of Manassas Junction and await Lee’s arrival. Orders were at once issued for a manœuvre which should ensure the defeat of the presumptuous foe. The Federal army corps, marching in three columns, were called up to Manassas, a movement which would leave Thoroughfare Gap unguarded save by Buford’s cavalry. Some were to move at midnight, others “at the very earliest blush of dawn.” “We shall bag the whole crowd, if they are prompt and expeditious,”[[18]] said Pope, with a sad lapse from the poetical phraseology he had just employed.
August 28 And so, on the morning of the 28th, a Federal army once more set out with the expectation of surrounding Jackson, to find once more that the task was beyond their powers.
The march was slow. Pope made no movement from Bristoe Station until Hooker had been reinforced by Kearney and Reno; McDowell, before he turned east from Gainesville, was delayed by Sigel’s trains, which crossed his line of march, and it was not till noon that Hooker’s advanced guard halted amid the still smouldering ruins on the Manassas plateau. The march had been undisturbed. The redoubts were untenanted. The woods to the north were silent. A few grey-coated vedettes watched the operations from far-distant ridges; a few stragglers, overcome perhaps by their Gargantuan meal of the previous evening, were picked up in the copses, but Jackson’s divisions had vanished from the earth.
