This was the first major land battle of the armies in Virginia. On July 16, 1861, the untried Union army under Brig. Gen. Irvin McDowell marched from Washington against the Confederate army, which was drawn up behind Bull Run beyond Centreville. On the 21st, McDowell crossed at Sudley Ford and attacked the Confederate left flank on Matthews Hill. Fighting raged throughout the day as Confederate forces were driven back to Henry Hill. Late in the afternoon, Confederate reinforcements (one brigade arriving by rail from the Shenandoah Valley) extended and broke the Union right flank. The Federal retreat rapidly deteriorated into a rout. Although victorious, Confederate forces were too disorganized to pursue. Confederate Gen. Bee and Col. Bartow were killed. Thomas J. Jackson earned the nom de guerre "Stonewall." By July 22, the shattered Union army reached the safety of Washington. This battle convinced the Lincoln administration that the war would be a long and costly affair. McDowell was relieved of command of the Union army and replaced by Maj. Gen. George B. McClellan, who set about reorganizing and training the troops.

In order to draw Pope's army into battle, Jackson ordered an attack on a Federal column that was passing across his front on the Warrenton Turnpike on August 28. The fighting at Brawner Farm lasted several hours and resulted in a stalemate. Pope became convinced that he had trapped Jackson and concentrated the bulk of his army against him. On August 29, Pope launched a series of assaults against Jackson's position along an unfinished railroad grade. The attacks were repulsed with heavy casualties on both sides. At noon, Longstreet arrived on the field from Thoroughfare Gap and took position on Jackson's right flank. On August 30, Pope renewed his attacks, seemingly unaware that Longstreet was on the field. When massed Confederate artillery devastated a Union assault by Fitz John Porter's command, Longstreet's wing of 28,000 men counterattacked in the largest, simultaneous mass assault of the war. The Union left flank was crushed and the army driven back to Bull Run. Only an effective Union rearguard action prevented a replay of the First Manassas disaster. Pope's retreat to Centreville was precipitous, nonetheless. The next day, Lee ordered his army in pursuit. This was the decisive battle of the Northern Virginia Campaign.
RESULTS: Confederate Victory
