Army of Northern Virginia
Lee sent Jackson’s Command to deal with Pope on the Rappahannock, resulting in the Battle of Cedar Mountain on August 9. With McClellan’s Army of the Potomac showing no signs of offensive intentions, Lee followed Jackson with Longstreet’s Command, and led both north in an attempt to destroy Pope. The result was the Second Battle of Bull Run and the withdrawal of Union forces into the Washington defenses. As August ended Lee prepared to move into Maryland.
