The action raged with great fury for several hours; the rebels constantly massing heavy columns against our lines, especially upon the left, where McDowell's and Sigel's corps resisted the onset with great bravery, but were at length forced to yield, when an utter rout took place; the whole army falling back upon Centreville in great disorder. On this day, for the first time in all these long series of battles, Porter's corps was brought into action. The conduct of the corps, in the early part of the day, showed a determination on the part of its leaders not to fight, and the men fell back in disorder; but being rallied later in the day, the pride of the men overcame the obstinacy of their commanders and the corps did good service. Hooker's and Kearney's divisions, and Reynolds' Pennsylvania reserves had rendered most gallant services from the time they reached General Pope's army.
Returning now to our Sixth corps under General Franklin. The corps remained quietly at Alexandria, from the morning of the 24th until the afternoon of the 29th. Rations and ammunition were as well supplied when we reached Alexandria as when we left. The booming of cannon was heard on the 26th and 27th, and contrabands and white refugees informed us that terrible fighting was in progress beyond Manassas. We wondered that we were not ordered to go to the relief of the little army which we knew was resisting the whole of Lee's and Jackson's forces.
On Thursday afternoon, August 28th, the corps received marching orders. Tents were struck, knapsacks packed, rations provided, and many regiments, shouldering their knapsacks, stood in line ready to move. But sunset came and no further orders. The men waited impatiently, only a few venturing to unpack their knapsacks or pitch their tents, until long after dark.
Friday morning brought few indications of an advance. Head-quarter tents remained standing, artillery horses stood unharnessed, and everything showed an intentional delay. At length the corps moved. Marching quietly and easily, the old ground of Camp Misery was passed, and the corps reached Annandale, where it halted and encamped after an easy march of six miles. Saturday morning the corps again moved leisurely along, making very frequent halts. The firing in front indicated a hardly contested battle, and our men, knowing that Pope must be in need of reinforcements, were anxious to push forward rapidly. Every hour the corps halted for at least twenty minutes, and sometimes even longer. At this snail pace we passed Fairfax Court House, the roar of musketry and artillery becoming constantly louder in front, and arrived at Centreville. Orders immediately came for the corps to proceed to Cub Run, about two miles beyond Centreville. Here, wounded men by hundreds and stragglers in greater numbers passed across the little bridge over the run, a dismal crowd, hastening toward Centreville.
As usual at such times, scores of cowardly villains were attempting to pass to the rear as wounded men.
An amusing encounter occurred between one of this class, a coward in captain's uniform, and one of our own officers, Captain Deyoe, as brave a fellow as ever drew a sword. The demoralized captain, his sword thrown away and its sheath after it, came hurriedly upon the bridge, where Deyoe was sitting, coolly filling his pipe. The fugitive captain turned his face, pale with fright, to the imperturbable Deyoe, and, striking him on the shoulder, said with as much composure as he could muster, "Captain, we have had hard times of it out there, but don't be afraid, don't be afraid." Deyoe, turning his face toward that of the straggler with a look of unruffled coolness and unmitigated contempt, replied, "Well, who the d—is afraid? Oh, yes, I see, you are. Well, you had better get away from here then!"
The corps remained at Cub Run until nightfall, when it was ordered to return to Centreville, where it encamped. Regiments from our Third brigade were sent to the rear of Centreville to arrest stragglers, who were hurrying toward Alexandria in great numbers.
The regiments were drawn up in line across the turnpike, where they remained all night, turning back hundreds of stragglers at the point of the bayonet.
The scene at Centreville on the next day was one of the utmost confusion. Thousands of stragglers wandered about without knowing or caring what had become of their commands; long columns of shattered regiments and batteries filed past to take up new positions, either within the intrenchments or on the flanks. The appearance of these skeletons of regiments and batteries gave evidence of the terrible experiences of this long series of engagements. Their ranks, thinned by the fortunes of battle, and still more by the disgraceful skulking which had become so universal, the worn and weary appearance of the men, their flags, each surrounded by only enough men to constitute a respectable color-guard, all showed that even the hard experiences of the Army of the Potomac had never had so demoralizing an effect as this.
The skulkers were loud-mouthed in their denunciations of General McDowell. Hundreds of them, who had in all probability not been near enough to the front during the whole retreat to know anything that was going on there, declared that they had seen him waving that mystic white hat as a signal to the rebels; and all knew that it was through his treachery that the army had been destroyed. Others declared positively that they had seen, with their own eyes, General McClellan, with a small body of faithful followers, dash against the advancing foe, and arrest the pursuit! Such wild and improbable stories filled the whole atmosphere, and, strangest of all, were believed by thousands, not only in the army, but throughout the whole north.
