In the morning Hooker had ridden around his whole line, and cheers received him as he came.
Scouts had brought him word that Jackson was moving, and he had taken note of the encounter with the rearguard of Stonewall's force.

But as that force continued its march into the deep forest and disappeared from sight, the brave and sanguine Hooker was confirmed in his opinion that the whole Southern army was retreating.

His belief was so firm that he sent a dispatch to Sedgwick, commanding the detached force near Fredericksburg, to pursue vigorously, as the enemy was fleeing in an effort to save his train.
While Hooker was writing this dispatch the "fleeing enemy," led by the greatest of Lee's lieutenants, lay in full force on his flank, almost within rifle-shot, preparing with calmness and in detail for one of the greatest blows ever dealt in war.

Truly no soldiers ever deserved higher praise than those of the Army of the Potomac, who, often misled and mismanaged by second-rate men, grew better and better after every defeat, and never failed to go into battle zealous and full of courage.
It seemed almost incredible to Harry, who had twice looked down upon them, that the whole Union right should remain ignorant of Jackson's presence.

Twenty-eight regiments and six batteries strong, the Northern troops were now getting ready to cook their suppers, and there was much laughter and talk as they looked around at the forest and wondered when they would be sent in pursuit of the fleeing enemy.
