No less than three captive balloons, in charge of skilled observers, looked down upon the Confederate earthworks.[[19]] Signal stations and observatories had been established on each commanding height; a line of field telegraph had been laid from Falmouth to United States Ford, and the chief of the staff, General Butterfield, remained at the former village in communication with General Sedgwick. If the weather were clear, and the telegraph did not fail, it seemed impossible that either wing of the Federal army could fail to be fully and instantly informed of the situation of the other, or that a single Confederate battalion could change position without both Hooker and Sedgwick being at once advised.

Moreover, the Federal Commander-in-Chief was so certain that Lee would retreat that his deficiency in cavalry troubled him not at all. He had determined to carry out his original design.

May 1 The next morning—May 1—the right wing was to move by the plank road and uncover Banks’ Ford, thus still further shortening the line of communication between the two wings; and as the chief of the staff impressed on Sedgwick, it was “expected to be on the heights west of Fredericksburg at noon or shortly after, or, if opposed strongly, at night.” Sedgwick, meanwhile, was “to observe the enemy’s movements with the utmost vigilance; should he expose a weak point, to attack him in full force and destroy him; should he show any symptom of falling back, to pursue him with the utmost vigour.”[[20]]

But Hooker was to find that mere mechanical precautions are not an infallible remedy for a dangerous situation. The Confederates had not only learned long since the importance of concealment, and the advantage of night marches, but in the early morning of May 1 the river mists rendered both balloons and observatories useless. Long before the sun broke through the fog, both McLaws and Jackson had joined Anderson at Tabernacle Church, and a strong line of battle had been established at the junction of the two roads, the pike and the plank, which led east from Chancellorsville. The position was favourable, running along a low ridge, partially covered with timber, and with open fields in front. Beyond those fields, a few hundred paces distant, rose the outskirts of a great forest, stretching far away over a gently undulating country. This forest, twenty miles in length from east to west, and fifteen in breadth from north to south, has given to the region it covers the name of the Wilderness of Spotsylvania, and in its midst the Federal army was now involved. Never was ground more unfavourable for the manœuvres of a large army. The timber was unusually dense. The groves of pines were immersed in a sea of scrub-oak and luxuriant undergrowth. The soil was poor. Farms were rare, and the few clearings were seldom more than a rifle shot in width. The woodland tracks were seldom travelled; streams with marshy banks and tortuous courses were met at frequent intervals, and the only débouchée towards Fredericksburg, the pike, the plank road, an unfinished line of railway a mile south of their junction, and the river road, about two miles north, were commanded from the Confederate position.

8 a.m. When Jackson arrived upon the scene, Anderson, with the help of Lee’s engineers, had strongly intrenched the whole front. A large force of artillery had already taken post. The flanks of the line were covered; the right, which extended to near Duerson’s Mill, by Mott’s Run and the Rappahannock; the left, which rested on the unfinished railroad not far from Tabernacle Church, by the Massaponax Creek. For the defence of this position, three miles in length, there were present 45,000 infantry, over 100 guns, and Fitzhugh Lee’s brigade of cavalry, a force ample for the purpose, and giving about nine men to the yard. On the rolling ground eastward there was excellent cover for the reserves, and from the breastworks to the front the defiles, for such, owing to the density of the wood, were the four roads by which the enemy must approach, might be so effectively swept as to prevent him from deploying either artillery or infantry.

But Jackson was not disposed to await attack. Only 10,000 men remained in the Fredericksburg lines to confront Sedgwick, and if that officer acted vigorously, his guns would soon be heard in rear of the lines at Tabernacle Church. Work on the intrenchments was at once broken off, and the whole force was ordered to prepare for an immediate advance on Chancellorsville.

10.45 a.m. Before eleven o’clock the rear brigades had closed up; and marching by the pike and the plank road, with a regiment of cavalry in advance, and Fitzhugh Lee upon the left, the Confederate army plunged resolutely into the gloomy depths of the great forest. Anderson’s division led the way, one brigade on the pike, and two on the plank road; a strong line of skirmishers covered his whole front, and his five batteries brought up the rear. Next in order came McLaws, together with the two remaining brigades of Anderson, moving by the pike, while Jackson’s three divisions were on the plank road. The artillery followed the infantry.

About a mile towards Chancellorsville the Federal cavalry was found in some force, and as the patrols gave way, a heavy force of infantry was discovered in movement along the pike. General McLaws, who had been placed in charge of the Confederate right, immediately deployed his four leading brigades, and after the Federal artillery, unlimbering in an open field, had fired a few rounds, their infantry advanced to the attack. The fight was spirited but short. The Northern regulars of Sykes’ division drove in the Confederate skirmishers, but were unable to make ground against the line of battle. Jackson, meanwhile, who had been at once informed of the encounter, had ordered the troops on the plank road to push briskly forward, and the Federals, finding their right in danger of being enveloped, retired on Chancellorsvile. Another hostile column was shortly afterwards met on the plank road, also marching eastward. Again there was a skirmish, and again Jackson, ordering a brigade to march rapidly along the unfinished railroad, had recourse to a turning movement; but before the manœuvre was completed, the Federals began to yield, and all opposition gradually melted away. The following order was then sent to McLaws:—
