Stonewall Jackson and the American Civil War

by G. F. R. Henderson

To attack this force, even after Jackson’s arrival, was to court disaster. The right was protected by the Chickahominy, the left rested on White Oak Swamp, a network of sluggish streams and impassable swamps, screened everywhere by tangled thickets. It needed not the presence of the siege ordnance, placed on the most commanding points within the lines, to make such a position absolutely impregnable.

North of the Chickahominy, however, the Federals were less favourably situated. The Fifth Army Corps, 25,000 strong,[^[9]] under General FitzJohn Porter, had been pushed forward, stretching a hand to McDowell and protecting the railway, in the direction of Mechanicsville; and although the tributaries of the Chickahominy, running in from the north, afforded a series of positions, the right flank of these positions, resting, as Stuart had ascertained, on no natural obstacle, was open to a turning movement. Furthermore, in rear of the Fifth Corps, and at an oblique angle to the front, ran the line of supply, the railway to West Point. If Porter’s right were turned, the Confederates, threatening the railway, would compel McClellan to detach largely to the north bank of the Chickahominy in order to recover or protect the line.

On the north bank of the Chickahominy, therefore, Lee’s attention had been for some time fixed. Here was his adversary’s weak point, and a sudden assault on Porter, followed up, if necessary, by an advance against the railway, would bring McClellan out of his intrenchments, and force him to fight at a disadvantage. To ensure success, however, in the attack on Porter it was necessary to concentrate an overwhelming force on the north bank; and this could hardly be done without so weakening the force which held the Richmond lines that it would be unable to resist the attack of the 75,000 men who faced it. If McClellan, while Lee was fighting Porter, boldly threw forward the great army he had on the south bank, the rebel capital might be the reward of his resolution. The danger was apparent to all, but Lee resolved to risk it, and his audacity has not escaped criticism. It has been said that he deliberately disregarded the contingency of McClellan either advancing on Richmond, or reinforcing Porter. The truth is, however, that neither Lee, nor those generals about him who knew McClellan, were in the least apprehensive that their over-cautious adversary, if the attack were sudden and well sustained, would either see or utilise his opportunity.

From Hannibal to Moltke there has been no great captain who has neglected to study the character of his opponent, and who did not trade on the knowledge thus acquired, and it was this knowledge which justified Lee’s audacity.

The real daring of the enterprise lay in the inferiority of the Confederate armament. Muskets and shot-guns, still carried by a large part of the army, were ill-matched against rifles of the most modern manufacture; while the smooth-bore field-pieces, with which at least half the artillery was equipped, possessed neither the range nor the accuracy of the rifled ordnance of the Federals.

That Lee’s study of the chances had not been patient and exhaustive it is impossible to doubt. He was no hare-brained leader, but a profound thinker, following the highest principles of the military art. That he had weighed the disconcerting effect which the sudden appearance of the victorious Jackson, with an army of unknown strength, would produce upon McClellan, goes without saying. He had omitted no precaution to render the surprise complete, and although the defences of Richmond were still too weak to resist a resolute attack, Magruder, the same officer who had so successfully imposed upon McClellan at Yorktown, was such a master of artifice that, with 28,000 men and the reserve artillery,[^[10]] he might be relied upon to hold Richmond until Porter had been disposed of. The remainder of the army, 2,000 of Stuart’s cavalry, the divisions of Longstreet and the two Hills, 35,000 men all told, crossing to the north bank of the Chickahominy and combining with the 18,500 under Jackson, would be sufficient to crush the Federal right.

The initial operations, however, were of a somewhat complicated nature. Four bridges[^[11]] crossed the river on Lee’s left. A little more than a mile and a half from Mechanicsville Bridge, up stream, is Meadow Bridge, and five and a half miles further up is another passage at the Half Sink, afterwards called Winston’s Bridge. Three and a half miles below Mechanicsville Bridge is New Bridge. The northern approaches to Mechanicsville, Meadow, and New Bridge, were in possession of the Federals; and it was consequently no simple operation to transfer the troops before Richmond from one bank of the Chickahominy to the other. Only Mechanicsville and Meadow Bridges could be used. Winston’s Bridge was too far from Richmond, for, if Longstreet and the two Hills were to cross at that point, not only would Magruder be left without support during their march, but McClellan, warned by his scouts, would receive long notice of the intended blow and have ample time for preparation. To surprise Porter, to give McClellan no time for reflection, and at the same time to gain a position which would bring the Confederates operating on the north bank into close and speedy communication with Magruder on the south, another point of passage must be chosen. The position would be the one commanding New Bridge, for the Confederate earthworks, held by Magruder, ran due south from that point. But Porter was already in possession of the coveted ground, with strong outposts at Mechanicsville. To secure, then, the two centre bridges was the first object. This, it was expected, would be achieved by the advance of the Valley army, aided by a brigade from the Half Sink, against the flank and rear of the Federals at Mechanicsville. Then, as soon as the enemy fell back, Longstreet and the two Hills would cross the river by the Meadow and Mechanicsville Bridges, and strike Porter in front, while Jackson attacked his right. A victory would place the Confederates in possession of New Bridge, and the troops north of the Chickahominy would be then in close communication with Magruder.

Lee’s orders were as follows:—’Headquarters, Army of Northern Virginia, June 24, 1862. General Orders, No. 75.

“I.—General Jackson’s command will proceed to-morrow (June 25) from Ashland towards the Slash (Merry Oaks) Church, and encamp at some convenient point west of the Central Railroad. Branch’s brigade of A. P. Hill’s division will also, to-morrow evening, take position on the Chickahominy, near Half Sink. At three o’clock Thursday morning, 26th instant, General Jackson will advance on the road leading to Pole Green Church, communicating his march to General Branch, who will immediately cross the Chickahominy, and take the road leading to Mechanicsville. As soon as the movements of these columns are discovered, General A. P. Hill, with the rest of his division, will cross the Chickahominy at Meadow Bridge, and move direct upon Mechanicsville. To aid his advance the heavy batteries on the Chickahominy will at the proper time open upon the batteries at Mechanicsville. The enemy being driven from Mechanicsville and the passage of the bridge being opened, General Longstreet, with his division and that of General D. H. Hill, will cross the Chickahominy at or near that point; General D. H. Hill moving to the support of General Jackson, and General Longstreet supporting General A. P. Hill; the four divisions keeping in communication with each other, and moving en échelon on separate roads if practicable; the left division in advance, with skirmishers and sharp-shooters extending in their front, will sweep down the Chickahominy, and endeavour to drive the enemy from his position above New Bridge, General Jackson bearing well to his left, turning Beaver Dam Creek, and taking the direction towards Cold Harbour. They will then press forward towards the York River Railroad, closing upon the enemy’s rear, and forcing him down the Chickahominy. An advance of the enemy towards Richmond will be prevented by vigorously following his rear, and crippling and arresting his progress.

“II.—The divisions under Generals Huger and Magruder will hold their position in front of the enemy against attack, and make such demonstrations, Thursday, as to discover his operations. Should opportunity offer, the feint will be converted into a real attack. . . .
