The culmination of the North Virginia campaign in 1862, the Union army led by John Pope faced the Confederates under General Robert E. Lee. Fought near the Bull Run tributary of the Potomac River half of Lee's army under Major General Stonewall Jackson attacked Pope's forces on the 29th with large losses on both sides.
The next day the rest of Lee's army under lieutenant General James Longstreet launched a surprise right flanking attack in what was to be the largest simultaneous mass assault of the war. Pope's forces could only retreat and starve off complete disaster by rearguard action.
