Dick heard about night that Jackson had marched ten miles, through fields deep in mud, and meant to fall on Pope's flank or rear again.

Stuart and his unresting cavalry were also on their right flank and in the rear, doing damage everywhere.

Longstreet had sent a brigade across Bull Run, and at many points the enemy was pressing closer.
The next morning, Pope, alarmed by all the sinister movements on his flanks and in his rear, gathered up his army and retreated.

It was full time or the vise would have shut down on him again.

Late that day the division under Kearney came into contact with Jackson's flanking force in the forest.
