The reader who has the heart to follow this chronicle to the end will assuredly find reason to doubt the acumen, however he may admire the eloquence, of Jackson’s brother-in-law. When he reads of the Second Manassas, of Harper’s Ferry, of Sharpsburg and of Chancellorsville, he will recall this statement with astonishment; and it will not be difficult to show that Jackson conformed as closely to the plans of his commander at Mechanicsville as elsewhere.
The machinery of war seldom runs with the smoothness of clockwork. The course of circumstances can never be exactly predicted. Unforeseen obstacles may render the highest skill and the most untiring energy of no avail; and it may be well to point out that the task which was assigned to Jackson was one of exceeding difficulty. In the first place, his march of eight-and-twenty miles, from Frederickshall to Ashland, on June 23, 24, and 25, was made over an unmapped country, unknown either to himself or to his staff, which had lately been in occupation of the Federals. Bridges had been destroyed and roads obstructed. The Valley army had already marched far and fast; and although Dabney hints that inexperienced and sluggish subordinates were the chief cause of delay, there is hardly need to look so far for excuse.[[18]] The march from Ashland to Hundley’s Corner, sixteen miles, was little less difficult. It was made in two columns, Whiting and the Stonewall division, now under Winder, crossing the railway near Merry Oaks Church, Ewell moving by Shady Grove Church, but this distribution did not accelerate the march. The midsummer sun blazed fiercely down on the dusty roads; the dense woods on either hand shut out the air, and interruptions were frequent. The Federal cavalry held a line from Atlee’s Station to near Hanover Court House. The 8th Illinois, over 700 strong, picketed all the woods between the Chickahominy and the Totopotomoy Creek. Two other regiments prolonged the front to the Pamunkey, and near Hundley’s Corner and Old Church were posted detachments of infantry. Skirmishing was constant. The Federal outposts contested every favourable position. Here and there the roads were obstructed by felled trees; a burned bridge over the Totopotomoy delayed the advance for a full hour, and it was some time before the enemy’s force at Hundley’s Corner was driven behind Beaver Dam Creek.
At the council of war, held on the 23rd, Lee had left it to Jackson to fix the date on which the operation against the Federal right should begin, and on the latter deciding on the 26th, Longstreet had suggested that he should make more ample allowance for the difficulties that might be presented by the country and by the enemy, and give himself more time.[[19]] Jackson had not seen fit to alter his decision, and it is hard to say that he was wrong.
Had McClellan received notice that the Valley army was approaching, a day’s delay would have given him a fine opportunity. More than one course would have been open to him. He might have constructed formidable intrenchments on the north bank of the Chickahominy and have brought over large reinforcements of men and guns; or he might have turned the tables by a bold advance on Richmond. It was by no means inconceivable that if he detected Lee’s intention and was given time to prepare, he might permit the Confederates to cross the Chickahominy, amuse them there with a small force, and hurl the rest of his army on the works which covered the Southern capital. It is true that his caution was extreme, and to a mind which was more occupied with counting the enemy’s strength than with watching for an opportunity, the possibility of assuming the offensive was not likely to occur. But, timid as he might be when no enemy was in sight, McClellan was constitutionally brave; and when the chimeras raised by an over-active imagination proved to be substantial dangers, he was quite capable of daring resolution. Time, therefore, was of the utmost importance to the Confederates. It was essential that Porter should be overwhelmed before McClellan realised the danger; and if Jackson, in fixing a date for the attack which would put a heavy tax on the marching powers of his men, already strained to the utmost, ran some risks, from a strategical point of view those risks were fully justified.
In the second place, an operation such as that which Lee had devised is one of the most difficult manœuvres which an army can be called upon to execute. According to Moltke, to unite two forces on the battle-field, starting at some distance apart, at the right moment, is the most brilliant feat of generalship. The slightest hesitation may ruin the combination. Haste is even more to be dreaded. There is always the danger that one wing may attack, or be attacked, while the other is still far distant, and either contingency may be fatal. The Valley campaign furnishes more than one illustration. In their pursuit of Jackson, Shields and Fremont failed to co-operate at Strasburg, at Cross Keys, and at Port Republic. And greater generals than either Shields or Fremont have met with little better success in attempting the same manœuvre. At both Eylau and Bautzen Napoleon was deprived of decisive victory by his failure to ensure the co-operation of his widely separated columns.
Jackson and A. P. Hill, on the morning of the 26th, were nearly fifteen miles apart. Intercommunication at the outset was ensured by the brigade under Branch; but as the advance progressed, and the enemy was met with, it became more difficult. The messengers riding from one force to the other were either stopped by the Federals, or were compelled to make long détours; and as they approached the enemy’s position, neither Hill nor Jackson was informed of the whereabouts of the other.
The truth is, that the arrangements made by the Confederate headquarter staff were most inadequate. In the first place, the order of the 24th, instructing Jackson to start from Slash Church at 3 a.m. on the 26th, and thus leading the other generals to believe that he would certainly be there at that hour, should never have been issued. When it was written Jackson’s advanced guard was at Beaver Dam Station, the rear brigades fifteen miles behind; and to reach Slash Church his force had to march forty miles through an intricate country, in possession of the enemy, and so little known that it was impossible to designate the route to be followed. To fix an hour of arrival so long in advance was worse than useless, and Jackson cannot be blamed if he failed to comply with the exact letter of a foolish order. As it was, so many of the bridges were broken, and so difficult was it to pass the fords, that if Dr. Dabney had not found in his brother, a planter of the neighbourhood, an efficient substitute for the guide headquarters should have provided, the Valley army would have been not hours but days too late. In the second place, the duty of keeping up communications should not have been left to Jackson, but have been seen to at headquarters. Jackson had with him only a few cavalry, and these few had not only to supply the necessary orderlies for the subordinate generals, and the escorts for the artillery and trains, but to form his advanced guard, for Stuart’s squadrons were on his left flank, and not in his front. Moreover, his cavalry were complete strangers to the country, and there were no maps. In such circumstances the only means of ensuring constant communication was to have detached two of Stuart’s squadrons, who knew the ground, to establish a series of posts between Jackson’s line of march and the Chickahominy; and to have detailed a staff officer, whose sole duty would have been to furnish the Commander-in-Chief with hourly reports of the progress made, to join the Valley army.[[20]] It may be remarked, too, that Generals Branch and Ewell, following converging roads, met near Shady Grove Church about 3 p.m. No report appears to have been sent by the latter to General A. P. Hill; and although Branch a little later received a message to the effect that Hill had crossed the Chickahominy and was moving on Mechanicsville,[[21]] the information was not passed on to Jackson.
Neglect of these precautions made it impracticable to arrange a simultaneous attack, and co-operation depended solely on the judgment of Hill and Jackson. In the action which ensued on Beaver Dam Creek there was no co-operation whatever. Hill attacked and was repulsed. Jackson had halted at Hundley’s Corner, three miles distant from the battle-field. Had the latter come down on the Federal rear while Hill moved against their front an easy success would in all probability have been the result.
Nevertheless, the responsibility for Hill’s defeat cannot be held to rest on Jackson’s shoulders. On August 18, 1870, the Prussian Guards and the Saxon Army Corps were ordered to make a combined attack on the village of St. Privat, the Guards moving against the front, the Saxons against the flank. When the order was issued the two corps were not more than two miles apart. The tract of country which lay between them was perfectly open, the roads were free, and inter-communication seemed easy in the extreme. Yet, despite their orders, despite the facilities of communication, the Guards advanced to the attack an hour and a half too soon; and from six o’clock to nearly seven their shattered lines lay in front of the position, at the mercy of a vigorous counterstroke, without a single Saxon regiment coming to their aid. But the Saxons were not to blame. Their march had been unchecked; they had moved at speed. On their part there had been no hesitation; but on the part of the commander of the Guards there had been the same precipitation which led to the premature attack on the Federal position at Beaver Dam Creek. It was the impatience of General Hill, not the tardiness of Jackson, which was the cause of the Confederate repulse.
We may now turn to the question whether Jackson was justified in not marching to the sound of the cannon. Referring to General Lee’s orders, it will be seen that as soon as Longstreet and D. H. Hill had crossed the Chickahominy the four divisions of the army were to move forward in communication with each other and drive the enemy from his position, Jackson, in advance upon the left, “turning Beaver Dam Creek, and taking the direction of Cold Harbour.”
