The meadows were trampled and red . Hundreds of weak and tired men were ridden down by cavalry and crushed by artillery . On and on rushed the remorseless machine of the Confederacy , crushing , killing , scarring , piling the dead in heaps . It was ten o'clock that night before the army of Lee halted and Pope 's exhausted lines fell into the trenches around Centreville for a few hours ' respite . At dawn Jackson was struggling with his tired victorious division to again turn Pope 's flank , get into his rear and cut off his retreat . A cold and drenching rainstorm delayed his march and the rabble that was once Pope 's army succeeded in getting into the defenses of Washington . Davis ' army took seven thousand prisoners and picked up more than two thousand wounded soldiers whom their boastful commander had left on the field to die .
