When did the first battle of Battle of Bull Run END?

I am presuming the question pertains to the aftermath of the First Battle of Bull Run.

In Washington DC there was disbelief that their army had been defeated. General McDowall, who had been goaded into starting the battle before he felt it was ready, was relieved of command. Some Union soldiers who ran from the battle were found guilty and branded as cowards (literally, with a hot branding iron). They were a small percentage of those soldiers who fled the battlefield in panic, but they were served up as examples, and other measures were taken to improve the army for the next battle.

In Richmond, although Bull Run had been a Southern victory, any illusions of a short glorious war against the North were shattered. Their army also saw a need to improve discipline, as many Confederate soldiers simply went home after the battle, thinking that a Southern victory in the war was assured. The Southern Generals Beuregard, Johnston, and Jackson became heroes in the public consciousness for driving the North from Virginia, with Generals Bee and Bartow receiving their hero honors posthumously.
