General Johnston, leaving Stuart with a little band of troopers to conceal his movements, immediately commenced his march from Winchester to Manassas. So skillfully did Colonel Stuart do his work that General Patterson was not aware of General Johnston’s departure until Sunday, July 21, when the great battle of Manassas was fought. Owing to a collision which had blocked the railway, some of the infantry did not reach Manassas until near the close of the battle, but the cavalry and the artillery marched all the way and arrived in time to render effective service during the entire battle. It was at Manassas that General Jackson won his name of “Stonewall” because of the wonderful stand that his brigade made, just when it seemed that the Federals were about to overcome the Confederates. But we are concerned particularly with the movements of the cavalry which rendered fine service, protecting each flank of the army. Colonel Stuart, with only two companies of cavalry, protected the left flank from assault after assault. At one time Stuart boldly charged the Federal right and drove back a company of Zouaves resplendent in their blue and scarlet uniforms and white turbans. General Early, who arrived on the field about three o’clock in the afternoon and assisted in holding the left flank, said, “But for Stuart’s presence there, I am of the opinion that my brigade would have arrived too late to be of any use. Stuart did as much toward saving the First Manassas as any subordinate who participated in it.” General Jackson, in his report of the battle, said: “Apprehensive lest my flanks be turned, I sent orders to Colonels Stuart and Radford of the cavalry to secure them. Colonel Stuart and that part of his command with him deserve great praise for the promptness with which they moved to my left and secured my flank from the enemy, and by driving them back.” Thus we see at the very crisis of the battle, Stuart with only a small force aided largely in gaining the great victory. When he saw the Federals fleeing from all parts of the field, he pursued them for twelve miles, taking many prisoners and securing much booty. After the battle of First Manassas, the main armies were inactive for many months; but the Confederate cavalry was kept busy in frequent skirmishes with the Federal pickets and in raids toward the Potomac river. Stuart took possession of Munson’s Hill, near Washington, and for several weeks sent out his pickets within sight of the dome of the Capitol.
