By distracting Pope to his front, while sending part of his army under Stonewall on a long, circuitous march to capture the Union supply depot.
When Pope heard of this, he turned to face Stonewall, but lost track of both parts of Lee's army. Eventually Lee and Stomewall re-united and sent Pope into a headlong retreat.

Second Bull Run
During the Second Battle of Bull Run, General John Pope was sent to command the Union forces in northern Virginia. His troops were positioned to engage the Confederate army, led by General Robert E. Lee. The battle took place from August 28 to August 30, 1862, and ultimately resulted in a significant defeat for Pope's forces. This loss led to his dismissal from command shortly afterward.
Although Second Bull Run was not a humiliating rout as First Bull Run had been for McDowell, it was still a Union loss. Pope was relieved of command and sent to Minnesota. He served creditably as a general for the rest of the war and after.

At the US Civil War Battle of the Second Bull Run, one positive result, even in defeat was the fact that the Union's loss could not be attributed to fielding an inexperienced army as was the case in the First Battle of Bull Run. Union General Pope's Army of the Potomac was experienced. Pope provided for an effective rear guard, and with fresh forces lending its support and the army was successful in evading the Confederate pursuit. At least the Army of the Potomac was well prepared if a defeat was seen. And, yes it was a defeat, but not as embarrassing as the First Bull Run.
