On the side of the Confederates only half the force had been engaged. Starke’s division never came into action, and of Hill’s and Lawton’s there were still brigades in reserve. 500 men were killed or wounded; but although the three Federal divisions are reported to have lost 1,000, they had held their ground, and Jackson was thwarted in his design. Pope’s trains and his whole army reached Fairfax Court House without further disaster. But the persistent attacks of his indefatigable foe had broken down his resolution. He had intended, he told Halleck, when Jackson’s march down the Little River turnpike was first announced, to attack the Confederates the next day, or “certainly the day after.”
Sept. 2 The action at Chantilly, however, induced a more prudent mood; and, on the morning of the 2nd, he reported that “there was an intense idea among the troops that they must get behind the intrenchments [of Alexandria]; that there was an undoubted purpose, on the part of the enemy, to keep on slowly turning his position so as to come in on the right, and that the forces under his command were unable to prevent him doing so in the open field. Halleck must decide what was to be done.” The reply was prompt, Pope was to bring his forces, “as best he could,” under the shelter of the heavy guns.
Whatever might be the truth as regards the troops, there could be no question but that the general was demoralised; and, preceded by thousands of stragglers, the army fell back without further delay to the Potomac. It was not followed except by Stuart. “It was found,” says Lee, in his official dispatch, ”that the enemy had conducted his retreat so rapidly that the attempt to interfere with him was abandoned. The proximity of the fortifications around Alexandria and Washington rendered further pursuit useless.”
On the same day General McClellan was entrusted with the defence of Washington, and Pope, permitted to resign, was soon afterwards relegated to an obscure command against the Indians of the North-west. His errors had been flagrant. He can hardly be charged with want of energy, but his energy was spasmodic; on the field of battle he was strangely indolent, and yet he distrusted the reports of others. But more fatal than his neglect of personal reconnaissance was his power of self-deception. He was absolutely incapable of putting himself in his enemy’s place, and time after time he acted on the supposition that Lee and Jackson would do exactly what he most wished them to do. When his supplies were destroyed, he concentrated at Manassas Junction, convinced that Jackson would remain to be overwhelmed. When he found Jackson near Sudley Springs, and Thoroughfare Gap open, he rushed forward to attack him, convinced that Longstreet could not be up for eight-and-forty hours. When he sought shelter at Centreville, he told Halleck not to be uneasy, convinced that Lee would knock his head against his fortified position. Before the engagement at Chantilly he had made up his mind to attack the enemy the next morning. A few hours later he reported that his troops were utterly untrustworthy, although 20,000 of them, under Franklin and Sumner, had not yet seen the enemy. In other respects his want of prudence had thwarted his best endeavours. His cavalry at the beginning of the campaign was effectively employed. But so extravagant were his demands on the mounted arm, that before the battle of Manassas half his regiments were dismounted. It is true that the troopers were still indifferent horsemen and bad horse-masters, but it was the fault of the commander that the unfortunate animals had no rest, that brigades were sent to do the work of patrols, and that little heed was paid to the physical wants of man and beast. As a tactician Pope was incapable. As a strategist he lacked imagination, except in his dispatches. His horizon was limited, and he measured the capacity of his adversaries by his own. He was familiar with the campaign in the Valley, with the operations in the Peninsula, and Cedar Run should have enlightened him as to Jackson’s daring. But he had no conception that his adversaries would cheerfully accept great risks to achieve great ends; he had never dreamt of a general who would deliberately divide his army, or of one who would make fifty-six miles in two marches.
Lee, with his extraordinary insight into character, had played on Pope as he had played on McClellan, and his strategy was justified by success. In the space of three weeks he had carried the war from the James to the Potomac. With an army that at no time exceeded 55,000 men he had driven 80,000 into the fortifications of Washington.[[5]] He had captured 30 guns, 7,000 prisoners, 20,000 rifles, and many stand of colours; he had killed or wounded 13,500 Federals, destroyed supplies and material of enormous value; and all this with a loss to the Confederates of 10,000 officers and men.
So much had he done for the South; for his own reputation he had done more. If, as Moltke avers, the junction of two armies on the field of battle is the highest achievement of military genius,[[6]] the campaign against Pope has seldom been surpassed; and the great counterstroke at Manassas is sufficient in itself to make Lee’s reputation as a tactician. Salamanca was perhaps a more brilliant example of the same manœuvre, for at Salamanca Wellington had no reason to anticipate that Marmont would blunder, and the mighty stroke which beat 40,000 French in forty minutes was conceived in a few moments. Nor does Manassas equal Austerlitz. No such subtle manœuvres were employed as those by which Napoleon induced the Allies to lay bare their centre, and drew them blindly to their doom. It was not due to the skill of Lee that Pope weakened his left at the crisis of the battle.[[7]] But in the rapidity with which the opportunity was seized, in the combination of the three arms, and in the vigour of the blow, Manassas is in no way inferior to Austerlitz or Salamanca. That the result was less decisive was due to the greater difficulties of the battle-field, to the stubborn resistance of the enemy, to the obstacles in the way of rapid and connected movement, and to the inexperience of the troops. Manassas was not, like Austerlitz and Salamanca, won by veteran soldiers, commanded by trained officers, perfect in drill and inured to discipline.
Lee’s strategic manœuvres were undoubtedly hazardous. But that an antagonist of different calibre would have met them with condign punishment is short-sighted criticism. Against an antagonist of different calibre, against such generals as he was afterwards to encounter, they would never have been attempted. “He studied his adversary,” says his Military Secretary, “knew his peculiarities, and adapted himself to them. His own methods no one could foresee-he varied them with every change in the commanders opposed to him. He had one method with McClellan, another with Pope, another with Hooker, another with Meade, and yet another with Grant.” Nor was the dangerous period of the Manassas campaign so protracted as might be thought. Jackson marched north from Jefferson on August 25. On the 26th he reached Bristoe Station. Pope, during these two days, might have thrown himself either on Longstreet or on Jackson. He did neither, and on the morning of the 27th, when Jackson reached Sudley Springs, the crisis had passed. Had the Federals blocked Thoroughfare Gap that day, and prevented Longstreet’s passage, Lee was still able to concentrate without incurring defeat. Jackson, retreating by Aldie Gap, would have joined Longstreet west of the mountains; Pope would have escaped defeat, but the Confederates would have lost nothing.
Moreover, it is well to remember that the Confederate cavalry was in every single respect, in leading, horsemanship, training, and knowledge of the country, superior to the Federal. The whole population, too, was staunchly Southern. It was always probable, therefore, that information would be scarce in the Federal camps, and that if some items did get through the cavalry screen, they would be so late in reaching Pope’s headquarters as to be practically useless. There can be no question that Lee, in these operations, relied much on the skill of Stuart. Stuart was given a free hand. Unlike Pope, Lee issued few orders as to the disposition of his horsemen. He merely explained the manœuvres he was about to undertake, pointed out where he wished the main body of the cavalry should be found, and left all else to their commander. He had no need to tell Stuart that he required information of the enemy, or to lay down the method by which it was to be obtained. That was Stuart’s normal duty, and right well was it performed. How admirably the young cavalry general co-operated with Jackson has already been described. The latter suggested, the former executed, and the combination of the three arms, during the whole of Jackson’s operations against Pope, was as close as when Ashby led his squadrons in the Valley.
Yet it was not on Stuart that fell, next to Lee, the honours of the campaign. Brilliant as was the handling of the cavalry, impenetrable the screen it formed, and ample the information it procured, the breakdown of the Federal horse made the task comparatively simple. Against adversaries whose chargers were so leg-weary that they could hardly raise a trot it was easy to be bold. One of Stuart’s brigadiers would have probably done the work as well as Stuart himself. But the handling of the Valley army, from the time it left Jefferson on the 25th until Longstreet reached Gainesville on the 29th, demanded higher qualities than vigilance and activity. Throughout the operations Jackson’s endurance was the wonder of his staff. He hardly slept. He was untiring in reconnaissance, in examination of the country and in observation of the enemy, and no detail of the march escaped his personal scrutiny. Yet his muscles were much less hardly used than his brain. The intellectual problem was more difficult than the physical. To march his army fifty-six miles in two days was far simpler than to maintain it on Pope’s flank until Longstreet came into line. The direction of his marches, the position of his bivouacs, the distribution of his three divisions, were the outcome of long premeditation. On the night of the 25th he disappeared into the darkness on the road to Salem leaving the Federals under the conviction that he was making for the Valley. On the 26th he moved on Bristoe Station, rather than on Manassas Junction, foreseeing that he might be interrupted from the south-west in his destruction of the stores. On the 27th he postponed his departure till night had fallen, moving in three columns, of which the column marching on Centreville, whither he desired that the enemy should follow, was the last to move. Concentrating at Sudley Springs on the 28th, he placed himself in the best position to hold Pope fast, to combine with Longstreet, or to escape by Aldie Gap; and on the 29th the ground he had selected for battle enabled him to hold out against superior numbers.
Neither strategically nor tactically did he make a single mistake. His attack on King’s division at Groveton, on the evening of the 28th, was purely frontal, and his troops lost heavily. But he believed King to be the flank-guard of a larger force, and under such circumstances turning movements were over-hazardous. The woods, too, prevented the deployment of his artillery; and the attack, in its wider aspect, was eminently successful, for the aim was not to defeat King, but to bring Pope back to a position where Lee could crush him. On the 29th his dispositions were admirable. The battle is a fine example of defensive tactics. The position, to use a familiar illustration, “fitted the troops like a glove.” It was of such strength that, while the front was adequately manned, ample reserves remained in rear. The left, the most dangerous flank, was secured by Bull Run, and massed batteries gave protection to the right. The distribution of the troops, the orders, and the amount of latitude accorded to subordinate leaders, followed the best models. The front was so apportioned that each brigadier on the fighting-line had his own reserve, and each divisional general half his force in third line. The orders indicated that counterstrokes were not to be pushed so far as to involve the troops in an engagement with the enemy’s reserves, and the subordinate generals were encouraged, without waiting for orders, and thus losing the occasion, to seize all favourable opportunities for counterstroke. The methods employed by Jackson were singularly like those of Wellington. A position was selected which gave cover and concealment to the troops, and against which the powerful artillery of a more numerous enemy was practically useless. These were the characteristics of Vimiera, Busaco, Talavera, and Waterloo. Nor did Jackson’s orders differ from those of the great Englishman.
