Bull Run

First Manassas

July 21, 1861

Fairfax County and Prince William County , Virginia

Matthews HillThough the Civil War began when Confederate troops shelled Fort Sumter on April 12, 1861, the war didn’t begin in earnest until the Battle of Bull Run, fought in Virginia just miles from Washington DC, on July 21, 1861. Popular fervor led President Lincoln to push a cautious Brigadier General Irvin McDowell, commander of the Union army in Northern Virginia, to attack the Confederate forces commanded by Brigadier General P.G.T. Beauregard, which held a relatively strong position along Bull Run, just northeast of Manassas Junction. The goal was to make quick work of the bulk of the Confederate army, open the way to Richmond, the Confederate capital, and end the war.

The morning of July 21st dawned on two generals planning to outflank their opponent’s left. Hindering the success of the Confederate plan were several communication failures and general lack of coordination between units. McDowell’s forces, on the other had, were hampered by an overly complicated plan that required complex synchronization.  Constant and repeated delays on the march and effective scouting by the Confederates gave his movements away, and, worst of all Patterson failed to occupy Johnston’s Confederate forces attention in the west.  McDowell’s forces began by shelling the Confederates across Bull Run.  Others crossed at Sudley Ford and slowly made their way to attack the Confederate left flank. At the same time as Beauregard sent small detachments to handle what he thought was only a distraction, he also sent a larger contingent to execute flanking a flanking movement of his own on the Union left.

Spectators at Bull RunFighting raged throughout the day as Confederate forces were driven back, despite impressive efforts by Colonel Thomas Jackson to hold important high ground at Henry House Hill, earning him the nom de guerre “Stonewall.” Late in the afternoon, Confederate reinforcements including those arriving by rail from the Shenandoah Valley extended the Confederate line and succeeded in breaking the Union right flank. At the battle’s climax Virginia cavalry under Colonel James Ewell Brown “Jeb” Stuart arrived on the field and charged into a confused mass of New Yorkers, sending them fleetly to the rear.  The Federal retreat rapidly deteriorated as narrow bridges, overturned wagons, and heavy artillery fire added to the confusion. The calamitous retreat was further impeded by the hordes of fleeing onlookers who had come down from Washington to enjoy the spectacle. Although victorious, Confederate forces were too disorganized to pursue. By July 22, the shattered Union army reached the safety of Washington. The Battle of Bull Run convinced the Lincoln administration and the North that the Civil 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.
