The smallest estimate of the forces actually engaged on the Southern side is eighteen thousand—while the Union forces which crossed Bull Run did not at any time count more than thirteen thousand. One brigade of McDowell’s eighteen thousand was not in the action, except in a vain effort to check the retreat. This brigade, of General Tyler’s division, was stationed at Stone Bridge, and never advanced upon the actual battle-field. The attack repulsed by Davies on the left wing, at Blackburn’s Ford, took place nearly two hours after the army was in retreat. In the loss of officers, the enemy was even more unfortunate than the Union army. The fall of General Bee, one of the bravest of their leaders, Bartow, Colonel Thomas, Colonel Hampton, Colonel Johnson, Lamar, and others, shed a gloom upon their victory, and greatly weakened their cause in the future. The Union loss was heavy, for the men who fell or were taken prisoners were among the bravest that marched with the army, but the loss of officers by death was inferior to that of the enemy, and though Corcoran and Wilcox were wounded and taken prisoners, they were not lost to their country. In ordnance and munitions of war the conquest was less important than might have been supposed. Many of the Union guns were rescued from the field during the next day. Of the fine horses attached to the ordnance a large proportion were killed, and others were saved by their drivers, who cut the traces, and rode them from the scene of battle. The loss in killed and wounded on the Union side, was 481 killed, 1,011 wounded, and 1,216 missing: total, 2,708. That of the enemy numbered, by Beauregard’s report, 393 killed, 1,200 wounded. The victory was a very important one to the South, as it gave prestige and force to a rebellion which, had the position of things been reversed, would, it is probable, have expired before the year went out. But in the North it only served to arouse the people to a pitch of excitement hitherto unparalleled; if troops had been sent forth in regiments before, they came in brigades after that defeat.
