The staff of a regular army is not always infallible. It would be hard to match the extraordinary series of blunders made by the staffs of the three armies—English, French, and Prussian—in the campaign of Waterloo, and yet there was probably no senior officer present in Belgium who had not seen several campaigns. But the art of war has made vast strides since Waterloo, and even since 1870. Under Moltke’s system, which has been applied in a greater or less degree to nearly all professional armies, the chance of mistakes has been much reduced. The staff is no longer casually educated and selected haphazard; the peace training of both officers and men is far more thorough; and those essential details on which the most brilliant conceptions, tactical and strategical, depend for success stand much less chance of being overlooked than in 1815. It is by the standard of a modern army, and not of those whose only school in peace was the parade-ground, that the American armies must be judged.
That Jackson’s tactical skill, and his quick eye for ground, had much to do with his victories can hardly be questioned. At Kernstown and Port Republic he seized the key of the position without a moment’s hesitation. At Winchester, when Ewell was checked upon the right, three strong brigades, suddenly thrown forward on the opposite flank, completely rolled up the Federal line. At Cross Keys the position selected for Ewell proved too formidable for Frémont, despite his superiority in guns. At Port Republic, Taylor’s unexpected approach through the tangled forest was at once decisive of the engagement. The cavalry charge at Front Royal was admirably timed; and the manner in which Ashby was employed throughout the campaign, not only to screen the advance but to check pursuit, was a proof of the highest tactical ability. Nor should the quick insight into the direction of Shields’ march on June 1, and the destruction of the bridges by which he could communicate with Frémont, be omitted. It is true that the operations in the Valley were not absolutely faultless. When Jackson was bent on an effective blow his impatience to bring the enemy to bay robbed him more than once of complete success. On the march to M’Dowell Johnson’s brigade, the advanced guard, had been permitted to precede the main body by seven miles, and, consequently, when Milroy attacked there was not sufficient force at hand for a decisive counterstroke. Moreover, with an ill-trained staff a careful supervision was most essential, and the waggon bridge at Port Republic should have been inspected by a trustworthy staff officer before Winder rushed across to fall on Tyler.
Errors of this nature, however instructive they may be to the student of war, are but spots upon the sun; and in finding in his subordinate such breadth of view and such vigour of execution, Lee was fortunate indeed. Jackson was no less fortunate when Ashby came under his command. That dashing captain of free-lances was undoubtedly a most valuable colleague. It was something to have a cavalry leader who could not only fight and reconnoitre, but who had sagacity enough to divine the enemy’s intentions. But the ideas that governed the employment of the cavalry were Jackson’s alone. He it was who placed the squadrons across Frémont’s road from Wardensville, who ordered the demonstrations against Banks, before both M’Dowell and Front Royal, and those which caused Frémont to retreat after Port Republic. More admirable still was the quickness with which he recognised the use that might be made of mounted riflemen. From the Potomac to Port Republic his horsemen covered his retreat, dismounting behind every stream and along the borders of every wood, checking the pursuers with their fire, compelling them to deploy their infantry, and then retreating rapidly to the next position. Day after day were the Federal advanced guards held in check, their columns delayed, and the generals irritated by their slippery foe. Meanwhile, the Confederate infantry, falling back at their leisure, were relieved of all annoyance. And if the cavalry was suddenly driven in, support was invariably at hand, and a compact brigade of infantry, supported by artillery, sent the pursuing horsemen to the right-about. The retreat of the Valley army was managed with the same skill as its advance, and the rear-guard tactics of the campaign are no less remarkable than those of the attack.
To judge from the Valley campaign, Jackson handled his horsemen with more skill than any other commander, Confederate or Federal. A cavalry that could defend itself on foot as well as charge in the saddle was practically a new arm, of far greater efficiency than cavalry of the old type, and Jackson at once recognised, not only its value; but the manner in which it could be most effectively employed. He was not led away by the specious advantages, so eagerly urged by young and ambitious soldiers, of the so-called raids. Even Lee himself, cool-headed as he was, appears to have been fascinated by the idea of throwing a great body of horsemen across his enemy’s communications, spreading terror amongst his supply trains, cutting his telegraphs, and destroying his magazines. In hardly a single instance did such expeditions inflict more than temporary discomfort on the enemy; and the armies were led more than once into false manœuvres, for want of the information which only the cavalry could supply. Lee at Malvern Hill and Gettysburg, Hooker at Chancellorsville, Grant at Spotsylvania, owed defeat, in great measure, to the absence of their mounted troops. In the Valley, on the contrary, success was made possible because the cavalry was kept to its legitimate duty—that is, to procure information, to screen all movements, to take part in battle at the decisive moment, and to carry out the pursuit.
With all his regard for Napoleon’s maxims, Jackson was no slave to rule. In war, circumstances vary to such an extent that a manœuvre, which at one time is manifestly unsound, may at another be the most judicious. The so-called rules are never binding; they merely point out the risks which are generally entailed by some particular course of action. There is no principle on which Napoleon lays more stress than that a general should never divide his force, either on the field of battle or the theatre of war. But when he marched to M’Dowell and left Ewell at Swift Run Gap, Jackson deliberately divided his forces and left Banks between them, knowing that the apparent risk, with an opponent like Banks, was no risk at all. At the battle of Winchester, too, there was a gap of a mile between the brigades on the left of the Kernstown road and Ewell on the right; and owing to the intervening hills, one wing was invisible to the other. Here again, like Moltke at Königgrätz, Jackson realised that the principle might be disregarded not only with impunity but with effect. He was not like Lord Galway, “a man who was in war what Molière’s doctors were in medicine, who thought it much more honourable to fail according to rule than to succeed by innovation.”[[24]]
But the triumphs of the Valley campaign were not due alone to the orders issued by Lee and Jackson. The Confederate troops displayed extraordinary endurance. When the stragglers were eliminated their stauncher comrades proved themselves true as steel. In every engagement the regiments fought with stubborn courage. They sometimes failed to break the enemy’s line at the first rush; but, except at Kernstown, the Federals never drove them from their position, and Taylor’s advance at Winchester, Trimble’s counterstroke at Cross Keys, the storming of the battery at Port Republic, and the charge of the cavalry at Cedarville, were the deeds of brave and resolute men.
A retreat is the most exhausting of military movements. It is costly in men, “more so,” says Napoleon, “than two battles,” and it shakes the faith of the soldiers in their general and in themselves. Jackson’s army retreated for seven days before Frémont, dwindling in numbers at every step, and yet it never fought better than when it turned at bay. From first to last it believed itself superior to its enemies; from first to last it was equal to the tasks which its exacting commander imposed upon it, and its spirit was indomitable throughout. “One male a week and three foights a day,” according to one of Jackson’s Irishmen, was the rule in the campaigns of 1862. The forced marches were not made in luxury. Not seldom only half-rations were issued, and more often none at all. The weather, for many days in succession, was abominable, and the forest bivouacs were comfortless in the extreme. On May 25 twenty per cent of Trimble’s brigade went into action barefoot; and had it not been for the stores captured in Winchester, the march to the Potomac, and the subsequent unmolested retreat to Woodstock, would have been hardly possible.
If the troops were volunteers, weak in discipline and prone to straggling, they none the less bore themselves with conspicuous gallantry. Their native characteristics came prominently to the front. Patient under hardships, vigorous in attack, and stubborn in defence, they showed themselves worthy of their commander. Their enthusiastic patriotism was not without effect on their bearing before the enemy. Every private in the ranks believed that he was fighting in the sacred cause of liberty, and the spirit which nerved the resolution of the Confederate soldier was the same which inspired the resistance of their revolutionary forefathers. His hatred of the Yankee, as he contemptuously styled the Northerner, was even more bitter than the wrath which Washington’s soldiers felt towards England; and it was intensified by the fact that his detested foeman had not only dared to invade the South, but had proclaimed his intention, in no uncertain tones, of dealing with the Sovereign States exactly as he pleased.
But it was something more than native courage and enthusiastic patriotism which inspired the barefooted heroes of Winchester. It would be difficult to prove that in other parts of the theatre of war the Confederate troops were inferior to those that held the Valley. Yet they were certainly less successful, and in very many instances they had failed to put forth the same resolute energy as the men who followed Jackson.
But it is hardly possible to discuss the spirit of an army apart from that of its commander. If, in strategy wholly, and in tactics in great part, success emanates from a single brain, the moral of the troops is not less dependent on the influence of one man. “Better an army of stags,” runs the old proverb, “led by a lion, than an army of lions led by a stag.”
