Up to this time, all the men appeared cool and fearless in the midst of the storm of lead and iron which fell around them. Col. Cameron had been borne from the field in an ambulance, mortally wounded. The rear of the field seemed filled with those who were being carried on litters, or were hobbling along to the hospitals. Gen. McDowell and all his generals were in the midst of the fight, sharing the perils of the young and inexperienced troops, who needed the encouragement which the utter disregard of shot and shell by their officers presented. Our troops were quite exhausted. They had been fighting, without a moment's intermission, from half-past ten in the morning, under a blazing sun, and choked with the dust and the smoke of the battle. They had been up most of the night, and had encountered a fatiguing march. To relieve themselves from encumbrance in the arduousness of the conflict, they had laid aside their knapsacks, and consequently could not refresh themselves even with a hurried lunch. Still, at this moment, the victory seemed to be decisively with the Union troops. "When I entered the field at two o'clock," says a correspondent of the Charleston (S. C.) Mercury, one of the most decided of the rebel journals, "the fortunes of the day were dark. The remnants of the regiments, so badly injured or wounded and worn, as they staggered out, gave gloomy pictures of the scene, and as, up to this time, after four hours of almost unprecedented valor and exertion, no point had been gained, the event was doubtful-hope seemed almost gone.' As on the battle-field of Waterloo, Wellington was looking anxiously for the coming of Blucher with a reënforcement of 65,000 Prussians, and Napoleon was watching for the arrival of Marshal Grouchy, who had been detached to pursue Blucher and absorb his energies; so, in this great and hard-fought battle at Bull Run, the rebels were looking hourly for Gen. Johnston's army of the Shenandoah, and the patriots were looking with equal eagerness, for the arrival of Patterson who, with 30,000 men, about forty miles distant, had been entrusted with the duty of assailing Johnston, and preventing his junction with the rebel troops. Johnston was the Blucher, and Patterson the Grouchy of this our miniature Waterloo. Gen. J. E. Johnston, who had assumed command of the rebel army, immediately upon his arrival, in his official report makes the following statement: "About 2 o'clock an officer of Gen. Beauregard's Adjutant-General's Office, galloped from Manassas to report to me that a United States army had reached the line of Manassas Gap railroad, was marching towards us, and then but three or four miles on our left flank.” As at Waterloo it was Blucher, not Grouchy, who came, so here it turned out that it was a division of Johnston's and not Patterson's army who were coming down upon the field. The rebel reënforcements pressed down with great impetuosity upon our wearied troops. Still the Unionists for a short time resisted these overpowering numbers with great valor, until overpowered, and threatened with assault upon both flanks, it was found necessary to retreat. A portion of Johnston's army had reached the field on Friday. The division which at this time arrived was that of |
