On the Southern side we find equally striking characters. General Joseph E. Johnston was not held by Patterson in the Valley and with a portion of his army had reached Manassas on the afternoon of the 20th. In the Indian wars of Jackson’s time Johnston had served his country; like McDowell and Beauregard, he had battled at the gates of Mexico; and like the latter he chose to cast his lot with the fortunes of the South. There, too, was Longstreet, who after the war was over, was to spend many years in the service of the country he was now seeking to divide. Most striking of all was “Stonewall” Jackson, whose brilliant military career was to astonish the world.

The Union plan for this fateful July day was that Tyler should lead his division westward by way of the Warrenton turnpike to a stone bridge that crossed Bull Run, about four miles from Centreville. At the same time the main army under Hunter and Heintzelman was to make a detour of several miles northward through a dense forest to a ford of Bull Run, known as Sudley’s Ford. Here they were to cross the stream, march down its right bank and, while Tyler guarded the Stone Bridge, engage the foe on the west side of Bull Run. The plan of the battle was admirably drawn, but the march around to Sudley’s Ford was slower than had been expected, and it was ten o’clock before the main army reached the point west of the Stone Bridge. While the Federals were making their plans to attack the Confederate left wing, Generals Beauregard and Johnston were planning an aggressive movement against the left wing of the Federal army. They were to cross Bull Run by fords several miles below the Stone Bridge and attack the Northern troops on the weaker wing of the Union force in an effort to rout them before relief could be sent from the Federal right. The Confederate attack was planned to take place a few hours later than McDowell had decided to move. The Southern troops were preparing to cross the stream when the boom of cannon at the Stone Bridge told that the Federals had taken the aggressive and that the weak Confederate left was in danger of being overwhelmed by the superior numbers of the Union right wing. Orders countermanding the command to attack were quickly sent to the Southerners at the lower fords, and preparations were hurriedly made to repulse the attack of the Northern force.

Tyler reached the Stone Bridge before six in the morning and opened fire on a Confederate force under Colonel Evans on the other side of the run. For some time this was kept up, and Evans was much puzzled that the Federals did not attempt to cross the bridge; they merely kept up a desultory fire. The failure of the Union troops to advance led Evans to believe that Tyler’s attack was only a feint and that the real attacking force would approach from some other direction. This belief was confirmed when he descried a lengthening line of dust above the tree-tops far in the distance, north of the Warrenton turnpike. Evans was now convinced (and he was right) that the main Union army was marching to Sudley’s Ford, three miles above the Stone Bridge, and would reach the field from that direction. Quickly then he turned about with six companies of brave South Carolinians and a battalion of “Louisiana Tigers” and posted them on a plateau overlooking the valley of Young’s Branch, a small tributary of Bull Run. Here, not far from the Matthews and Carter houses, he awaited the coming of the Federals.

His force was stationed overlooking the Sudley and Newmarket road and an open field through which the Federal troops would be forced to pass to reach the higher ground held by the Confederates. Two 6-pound howitzers were placed to sweep the field of approach, one at each end of Evans’ line of defense.

With guns loaded, and howitzers ready to pour their charges into an advancing force, the Southerners stood and watched the line of dust that arose above the trees. It moved slowly to the westward. Then, where the Sudley road turns to the southward to cross the Sudley Ford, it followed the trend of the highway. It reached the crossing of Bull Run, and the line of dust faded as the Federals spread into battle-line behind the expanse of woodland that hid each column from the other’s view.

It was nearing ten o’clock. The rays of the summer sun were beating in sweltering heat upon the waiting troops. Those who could find shelter beneath the trees moved from their places into the shade. Heavy banks of storm clouds were gathering on the horizon, giving promise of relief from oppressive warmth. A silence settled over the ranks of the Confederates as they watched the edge of the woodland for the first appearance of the approaching troops.

Suddenly there was a glimmer of the sunlight reflected from burnished steel among the trees. Then, in open battle array, the Federal advance guard, under the command of Colonel Burnside, emerged from the wood on a neighboring hill, and for the first time in the nation’s history two hostile American armies faced each other in battle array. At Fort Sumter only the stone walls had suffered; not a drop of human blood was shed. But here was to be a gigantic conflict, and thousands of people believed that here on this field on this day would be decided the fate of the Union and the fate of the Confederacy. The whole country awaited in breathless expectancy the news of this initial conflict, to become known as the battle of Bull Run.

With little delay the battle opened. The Federals had a clear advantage in numbers as their outlying forces came up; but they met with a brave resistance. General Bee, of South Carolina, with two brigades, crossed a valley to the south of Evans in the face of a heavy artillery fire to a point within one hundred yards of the Federal lines. At this short range thousands of shots were fired and many brave men and boys were stretched upon the green. The outcome at this point was uncertain until the Union forces were joined by Heintzelman with heavy reënforcements and by Sherman with a portion of Tyler’s division. Bee could now do nothing but withdraw, and in doing so his men fell into great disorder. Cheer after cheer arose from the ranks of the Union army.

Meanwhile, Generals Beauregard and Johnston had remained at the right of their line, near Manassas, nearly four miles from the scene of action, still determined to press their attack on the Federal left if the opportunity was offered. As the morning passed and the sounds of conflict became louder and extended further to the westward, it became evident to the Confederate leaders that the Federals were massing all their strength in an effort to crush the left of the Southern army. Plans for an aggressive movement were then abandoned, the commanders withdrawing all their reserve forces from the positions where they had been held to follow up the Confederate attack, and sending them to the support of the small force that was holding back the Federals. After dispatching troops to threaten the Union left, Johnston and Beauregard galloped at full speed to the scene of the battle. They arrived about noon—at the moment when Bee’s brigade was fleeing across the valley from the hail of Federal bullets. As the frightened men were running in the utmost disorder, General Bee, seeing Thomas J. Jackson’s brigade calmly waiting the onset, exclaimed to his men, “Look at Jackson; there he stands like a stone wall!” The expression spread to the army and to the world, and that invincible soldier has since been known as “Stonewall” Jackson.

Beauregard and Johnston found it a herculean task to rally the fleeing men and re-form the lines, but they succeeded at length; the battle was renewed, and from noon till nearly three o’clock it raged with greater fury than before. The fight was chiefly for the possession of the plateau called the Henry hill. Up and down the slopes the two armies surged in the broiling sun. Beauregard, like McDowell on the other side, led his men in the thickest of the fight. A bursting shell killed his horse under him and tore the heel from his boot; he mounted another horse and continued the battle. At half-past two the Confederates had been entirely driven from the plateau, had been pressed back for a mile and a half, and for the second time within three or four hours the Union troops raised the shout of victory.
