It is not improbable that Lee received information, crude but useful, about this portion of our army, from some women belonging to Dowdall's Tavern. When the Eleventh Corps occupied the place on Thursday, a watch was kept upon the family living there. But in the interval between the corps breaking camp to move out to Slocum's support on Friday morning, and its return to the old position, some of the women had disappeared. This fact was specially noted by Gen. Howard.
However the information was procured, the Federal right was doubtless ascertained to rest on high ground, where it was capable of making a stubborn resistance towards the south. But Lee well knew that its position was approached from the west by two broad roads, and reasoned justly that Hooker, in canvassing the events of Friday, would most probably look for an attack on his left or front.
Seated on a couple of cracker-boxes, the relics of an issue of Federal rations the day before, the two Confederate chieftains discussed the situation. Jackson, with characteristic restless energy, suggested a movement with his entire corps around Hooker's right flank, to seize United-States Ford, or fall unawares upon the Army of the Potomac. This hazardous suggestion, which Lee in his report does not mention as Jackson's, but which is universally ascribed to him by Confederate authorities, was one as much fraught with danger as it was spiced with dash, and decidedly bears the Jacksonian flavor. It gave "the great flanker" twenty-two thousand men (according to Col. A. S. Pendleton, his assistant adjutant-general, but twenty-six thousand by morning report) with which to make a march which must at best take all day, constantly exposing his own flank to the Federal assault. It separated for a still longer time the two wings of the Confederate army; leaving Lee with only Anderson's and McLaws's divisions,—some seventeen thousand men,—with which to resist the attack of thrice that number, which Hooker, should he divine this division of forces, could throw against him, the while he kept Jackson busy with the troops on his own right flank.
On the other hand, Hooker had shown clear intention of fighting a defensive battle; and perhaps Lee measured his man better than the Army of the Potomac had done. And he knew Jackson too. Should Hooker remain quiet during the day, either voluntarily or by Lee's engrossing his attention by constant activity in his front, the stratagem might succeed. And in case of failure, each wing had open ground and good roads for retreat, to form a junction towards Gordonsville.
Moreover, nothing better presented itself; and though, in the presence of a more active foe, Lee would never have hazarded so much, the very aggressiveness of the manoeuvre, and the success of Jackson's former flank attacks, commended it to Lee, and he gave his lieutenant orders to proceed to its immediate execution.
For this division of his forces in the presence of an enemy of twice his strength, Lee is not entitled to commendation. It is justifiable only—if at all—by the danger of the situation, which required a desperate remedy, and peculiarly by the success which attended it. Had it resulted disastrously, as it ought to have done, it would have been a serious blow to Lee's military prestige. The "nothing venture, nothing have" principle applies to it better than any maxim of tactics.
Before daybreak Jackson sends two of his aides, in company with some local guides, to find a practicable road, by which he may, with the greatest speed and all possible secrecy, gain the position he aims at on Hooker's right and rear, and immediately sets his corps in motion, with Rodes, commanding D. H. Hill's division, in the advance, and A. P. Hill bringing up the rear.
Jackson's route lay through the woods, along the road on which rested Lee's line. His corps, since Friday's manoeuvres, was on the left; and, as he withdrew his troops at dawn, Lee deployed to the left to fill the gap, first placing Wright where Jackson had been on the west of the plank road, and later, when Wright was ordered to oppose Sickles at the Furnace, Mahone's brigade.
This wood-road led to Welford's or Catherine's Furnace, from which place a better one, called the Furnace road, zigzagged over to join the Brock (or Brook) road, the latter running northerly into Y-shaped branches, each of which intersected the pike a couple of miles apart.
Jackson was obliged to make some repairs to the road as he advanced, for the passage of his artillery and trains. In many places the bottom, none too reliable at any time, was so soft with the recent rains, that it had to be corduroyed to pull the guns through. But these men were used to marches of unequalled severity, and their love for their leader made no work too hard when "Old Jack" shared it with them. And although they had already been marching and fighting continuously for thirty hours, this circuit of well-nigh fifteen miles was cheerfully done, with an alacrity nothing but willing and courageous hearts, and a blind belief that they were outwitting their enemy, could impart.
