The First Battle of Bull Run, Also known as the First Battle of Manassas, took place on July 21 1861, and was the first major land battle of the American Civil War. Unseasoned Union Army troops under Brigadier General Irvin McDowell advanced against the Confederate Army under Brig. Gens. Joseph E. Johnston and P.G.T. Beauregard at Manassas, Virginia, and despite early successes, were routed and forced to retreat back to Washington, D.C.

Background

Prior to the battle, Irvin McDowell was appointed by President Abraham Lincoln to command of the Army of Northeastern Virginia. Once in this capacity, McDowell was harassed by impatient politicians and citizens in Washington, who wished to see a quick battlefield victory over the Confederate Army in northern Virginia. McDowell, however, was concerned about the untried nature of his army. He was reassured by Lincoln, who responded, "You are green, it is true, but they are green also; you are all green alike." Against his better judgment, McDowell commenced campaigning. On July 16, 1861, the general departed Washington with the largest field army yet gathered on the North American continent, 28,452 effectives.^[1]

The Confederate Army of the Potomac (21,883 effectives^[1]) under Beauregard was encamped near Manassas Junction, approximately 25 miles from the United States capital. McDowell planned to swoop down upon this numerically inferior enemy army, while Union Major General Robert Patterson's 18,000 men engaged Johnston's force (the Army of the Shenandoah at 8,884 effectives, augmented by Theophilus H. Holmes's brigade of 1,465^[1]) in the Shenandoah Valley, preventing them from reinforcing Beauregard.

After two days of marching in the sweltering heat, the Union army was allowed to rest. In the meantime, McDowell searched for a way to outflank Beauregard, who had now drawn up his lines along Bull Run. On July 18, the Union commander sent a division under Brig. Gen. Daniel Tyler to pass on the Confederate right (southeast) flank. Unfortunately, Tyler was drawn into battle at Blackburn's Ford over Bull Run and made no headway. Now becoming more frustrated, McDowell resolved to attack the Confederate left (northwest) flank instead. He planned to leave one division at the Stone Bridge on the Warrenton Turnpike and send two divisions over Sudley Springs Ford. From here, these divisions could march into the Confederate rear. Though he had arrived at a sound plan, McDowell had delayed long enough that Johnston's Valley force was able to board trains at Piedmont Station and rush to Manassas Junction to reinforce Beauregard's men.

On July 19 and July 20, significant reinforcements bolstered the Confederate lines near Bull Run. However, it was not enough to hold back the flood of Union soldiers. General McDowell was getting contradictory information from his intelligence agents, and so he called for the balloon Enterprise, which was being demonstrated by Prof. Thaddeus S. C. Lowe in Washington, to perform aerial reconnaissance.

Battle

On the morning of July 21, divisions under David Hunter and Samuel P. Heintzelman crossed Sudley Springs and struck the Confederate left. All that stood in the path of the 6,000 Union soldiers were Confederate Col. Nathan Evans and his reduced brigade of 900 men. Evans had been informed of the Union flanking movement, and had hastily led most of his men from their position fronting the Stone Bridge to a new location on the slopes of Matthews Hill, a low rise to the northwest of his previous position.

Evans soon received reinforcement from two other brigades under Barnard Bee and Francis S. Bartow, but the Confederate line slowly crumbled, then broke completely. In a full run from their Matthews Hill position, the remainder of Evans's, Bee's, and Bartow's commands ran into a solid line of reinforcement on Henry House Hill. This was Thomas J. Jackson's Virginia brigade. "The Enemy are beating us back," Bee is reported to have told Jackson, who replied, "Then Sir, we shall give them the bayonet!" Inspired by the cool-headed Jackson, Bee returned to his men and shouted, "There stands Jackson like a stone wall! Rally behind the Virginians! " The immortal "Stonewall" Jackson had been born.

Scattered units began to rally around the Virginia brigade, and the fighting continued as the Union tide rolled onward, up the face of Henry House Hill. As soon as the Federal troops crested the hill, they were face to face with the rifles of Jackson's men and they took a full volley with devastating effect. They broke, and began to fall back in what was called the "Great Skedaddle". Eventually, more fresh Confederate brigades entered the fray and turned the tide of battle completely in favor of Beauregard's army. McDowell's flanking column was blunted, then crumbled and broke. In the disorder that followed, hundreds of Union troops were scooped up as prisoners. A Union wagon overturned on a bridge spanning Bull Run and incited panic in McDowell's force. Beauregard and Johnston decided not to press their advantage, since their combined army had been left highly disorganized as well.

The wealthy elite of nearby Washington, expecting an easy Union victory, had come to picnic and watch the battle. When the Union army was driven back in a running disorder, the roads back to Washington were blocked by panicked civilians attempting to flee in their carriages. Further confusion ensued when an artillery shell fell on a carriage, blocking the main road to the north.

Union forces and civilian alike feared that Confederate forces would now advance on Washington D.C. with very little standing in their way. On July 24, Prof. Lowe ascended in Enterprise to observe the Confederates moving in and about Manassas Junction and Fairfax and ascertained that there was no evidence of massing Rebel forces, but was forced to land in enemy territory. It was overnight before he was rescued and could report to headquarters. He reported that his observations "restored confidence" to the Union commanders.

Aftermath

Union casualties were 460 killed, 1,124 wounded, and 1,312 missing or captured; Confederate casualties were 387 killed, 1,582 wounded, and 13 missing.^[2] Among the latter was Col. Francis S. Bartow, who was the first Confederate brigade commander to be killed in the Civil War. General Bee was mortally wounded, dying the following day.

Irvin McDowell bore the brunt of the blame for the Union defeat at Bull Run and was soon replaced by George B. McClellan, who was named general-in-chief of all the Union armies. McDowell was also present to bear significant blame for the defeat of John Pope's Army of Virginia by Robert E. Lee's Army of Northern Virginia just thirteen months later, at the Second Battle of Bull Run.

Battlefield confusion relating to battle flags, especially the similarity of the Confederacy's "Stars and Bars" and the Union's "Stars and Stripes", led to the adoption of the Confederate Battle Flag, which eventually became the most popular symbol of the Confederacy and the South in general.
