Once again the warring armies met at the plains of Manassas but this time on a more expansive scale than the First Battle of Manassas/Bull Run. The Second Battle of Manassas/Bull Run Campaign was decisively more complex, and destructive. The Union General Pope was trying to out-maneuver Confederate General Lee in what would turn out to be the another crushing defeat for the Union army. The Union army once again had to retreat across Bull Run and through Fairfax County deflated.
"Stonewall" Jackson would also further his reputation as an outstanding leader in this battle, returning to the same battlefield in which he earned his famous nickname. The action that took place here would also set the stage for Lee's first invasion of the north.
The Battle of Ox Hill/Chantilly in Fairfax County would be the last major battle of the Second Manassas/Bull Run campaign when a portion of the Confederate army tried to outflank a section of the retreating Union army, and destroy them before they could reach the safety of the defenses of Washington DC.
