I speedily satisfied myself I could not finish my letter in time for post, and I therefore sent for my respectable Englishman to go direct to Boston by the train which leaves this at four o’clock to-morrow morning, so as to catch the mail steamer on Wednesday, and telegraphed to the agents there to inform them of my intention of doing so. Visitors came knocking at the door, and insisted on getting in—military friends who wanted to give me their versions of the battle—the attachés of legations and others who desired to hear the news and have a little gossip; but I turned a deaf ear doorwards, and they went off into the outer rain again.

More draggled, more muddy, and down-hearted, and foot-weary and vapid, the great army of the Potomac still straggled by. Towards evening I seized my hat and made off to the stable to inquire how the poor horse was. There he stood, nearly as fresh as ever, a little tucked up in the ribs, but eating heartily, and perfectly sound. A change had come over Mr. Wroe’s dream of horseflesh. “They’ll be going cheap now,” thought he, and so he said aloud, “If you’d like to buy that horse, I’d let you have him a little under what I said. Dear! dear! it must a’ been a sight sure-ly to see them Yankees running; you can scarce get through the Avenue with them.”

And what Mr. W. says is quite true. The rain has abated a little, and the pavements are densely packed with men in uniform, some with, others without, arms, on whom the shopkeepers are looking with evident alarm. They seem to be in possession of all the spirit-houses. Now and then shots are heard down the street or in the distance, and cries and shouting, as if a scuffle or a difficulty were occurring. Willard’s is turned into a barrack for officers, and presents such a scene in the hall as could only be witnessed in a city occupied by a demoralised army. There is no provost guard, no patrol, no authority visible in the streets. General Scott is quite overwhelmed by the affair, and is unable to stir. General M‘Dowell has not yet arrived. The Secretary of War knows not what to do, Mr. Lincoln is equally helpless, and Mr. Seward, who retains some calmness, is, notwithstanding his military rank and militia experience, without resource or expedient. There are a good many troops hanging on about the camps and forts on the other side of the river, it is said; but they are thoroughly disorganised, and will run away if the enemy comes in sight without a shot, and then the capital must fall at once. Why Beauregard does not come I know not, nor can I well guess. I have been expecting every hour since noon to hear his cannon. Here is a golden opportunity. If the Confederates do not grasp that which will never come again on such terms, it stamps them with mediocrity.

The morning papers are quite ignorant of the defeat, or affect to be unaware of it, and declare yesterday’s battle to have been in favour of the Federals generally, the least arrogant stating that M‘Dowell will resume his march from Centreville immediately. The evening papers, however, seem to be more sensible of the real nature of the crisis: it is scarcely within the reach of any amount of impertinence or audacious assertion to deny what is passing before their very eyes. The grand army of the Potomac is in the streets of Washington, instead of being on its way to Richmond. One paper contains a statement which would make me uneasy about myself if I had any confidence in these stories, for it is asserted “that Mr. Russell was last seen in the thick of the fight, and has not yet returned. Fears are entertained for his safety.”

Towards dark the rain moderated and the noise in the streets waxed louder; all kinds of rumours respecting the advance of the enemy, the annihilation of Federal regiments, the tremendous losses on both sides, charges of cavalry, stormings of great intrenchments and stupendous masked batteries, and elaborate reports of unparalleled feats of personal valour, were circulated under the genial influence of excitement, and by the quantities of alcohol necessary to keep out the influence of the external moisture. I did not hear one expression of confidence, or see one cheerful face in all that vast crowd which but a few days before constituted an army, and was now nothing better than a semi-armed mob. I could see no cannon returning, and to my inquiries after them, I got generally the answer, “I suppose the Seceshers have got hold of them.”

Whilst I was at table several gentlemen who have entrée called on me, who confirmed my impressions respecting the magnitude of the disaster that is so rapidly developing its proportions. They agree in describing the army as disorganised. Washington is rendered almost untenable, in consequence of the conduct of the army, which was not only to have defended it, but to have captured the rival capital. Some of my visitors declared it was dangerous to move abroad in the streets. Many think the contest is now over; but the gentlemen of Washington have Southern sympathies, and I, on the contrary, am persuaded this prick in the great Northern balloon will let out a quantity of poisonous gas, and rouse the people to a sense of the nature of the conflict on which they have entered. The inmates of the White House are in a state of the utmost trepidation, and Mr. Lincoln, who sat in the telegraph operator’s room with General Scott and Mr. Seward, listening to the dispatches as they arrived from the scene of action, left it in despair when the fatal words tripped from the needle and the defeat was clearly revealed to him.

Having finally cleared my room of visitors and locked the door, I sat down once more to my desk, and continued my narrative. The night wore on, and the tumult still reigned in the city. Once, indeed, if not twice, my attention was aroused by sounds like distant cannon and outbursts of musketry, but on reflection I was satisfied the Confederate general would never be rash enough to attack the place by night, and that, after all the rain which had fallen, he in all probability would give horses and men a day’s rest, marching them through the night, so as to appear before the city in the course of to-morrow. Again and again I was interrupted by soldiers clamouring for drink and for money, attracted by the light in my windows; one or two irrepressible and irresistible friends actually succeeded in making their way into my room—just as on the night when I was engaged in writing an account of the last attack on the Redan my hut was stormed by visitors, and much of my letter was penned under the apprehension of a sharp pair of spurs fixed in the heels of a jolly little adjutant, who, overcome by fatigue and rum-and-water, fell asleep in my chair, with his legs cocked up on my writing-table—but I saw the last of them about midnight, and so continued writing till the morning light began to steal through the casement. Then came the trusty messenger, and, at 3 a.m., when I had handed him the parcel and looked round to see all my things were in readiness, lest a rapid toilet might be necessary in the morning, with a sigh of relief I plunged into bed, and slept.

July 23rd.—The morning was far advanced when I awoke, and hearing the roll of waggons in the street, I at first imagined the Federals were actually about to abandon Washington itself; but on going to the window, I perceived it arose from an irregular train of commissariat carts, country waggons, ambulances, and sutlers’ vans, in the centre of the street, the paths being crowded as before with soldiers, or rather with men in uniform, many of whom seemed as if they had been rolling in the mud. Poor General Mansfield was running back and forwards between his quarters and the War Department, and in the afternoon some efforts were made to restore order, by appointing rendezvous to which the fragment of regiments should repair, and by organising mounted patrols to clear the streets. In the middle of the day I went out through the streets, and walked down to the long bridge with the intention of crossing, but it was literally blocked up from end to end with a mass of waggons and ambulances full of wounded men, whose cries of pain echoed above the shouts of the drivers, so that I abandoned the attempt to get across, which, indeed, would not have been easy with any comfort, owing to the depth of mud in the roads. To-day the aspect of Washington is more unseemly and disgraceful, if that were possible, than yesterday afternoon.

As I returned towards my lodgings a scene of greater disorder and violence than usual attracted my attention. A body of Confederate prisoners, marching two and two, were with difficulty saved by their guard from the murderous assaults of a hooting rabble, composed of civilians and men dressed like soldiers, who hurled all kinds of missiles they could lay their hands upon over the heads of the guard at their victims, spattering them with mud and filthy language. It was very gratifying to see the way in which the dastardly mob dispersed at the appearance of a squad of mounted men, who charged them boldly, and escorted the prisoners to General Mansfield. They consisted of a picket or grand guard, which, unaware of the retreat of their regiment from Fairfax, marched into the Federal lines before the battle. Their just indignation was audible enough. One of them, afterwards, told General M‘Dowell, who hurried over as soon as he was made aware of the disgraceful outrages to which they had been exposed, “I would have died a hundred deaths before I fell into these wretches’ hands, if I had known this. Set me free for five minutes, and let any two, or four, of them insult me when my hands are loose.”
