Longstreet was to glean the battle-field and then to follow Jackson.

The theory took root that cannonading has rain-making virtue.

Longstreet's advance reached Sudley Ford, and the care of the battle-field was left to the reenforcements from Richmond, which were now coming up. On Sept. 1, the march was resumed by Jackson at an early hour, and Longstreet followed over the same road.
Pope, in a despatch to Halleck during the night, had reported his falling back to Centreville, but had still claimed a victory, saying: The enemy is badly whipped and we shall do well enough.
Do not be uneasy
