This repulse was decisive, and General McClellan made no further attempt to pursue the adversary, who, standing at bay on the soil of Virginia, was still more formidable than he had been on the soil of Maryland. As we have intimated on a preceding page, the result of this attempt to pursue would seem to relieve General McClellan from the criticism of the Washington authorities. If he was repulsed with heavy slaughter in his attempt to strike at Lee on the morning of September 20th, it is not probable that an assault on his adversary on September 18th would have had different results.

No further crossing at that time was undertaken by the Federal commander. His army was moved toward Harper's Ferry, an important base for further operations, and Lee's army went into camp along the banks of the Opequan.

LEE AND McCLELLAN—THEIR MERITS IN THE MARYLAND CAMPAIGN.

General Lee and his adversary had displayed conspicuous merit in the campaign thus terminated, and we shall pause for a moment to glance back upon this great passage at arms.

To give precedence to General McClellan, he had assembled an army, after the defeat at Manassas, with a promptness for which only his own great personal popularity can adequately account, had advanced to check Lee, and had fully succeeded in doing so; and had thus not only protected the fertile territory of Pennsylvania from invasion, but had struck a death-blow for the time to any designs General Lee might have had to advance on the Federal capital. If the situation of affairs at that moment be attentively considered, the extreme importance of these results will not fail to appear. It may perhaps be said with justice, that General McClellan had saved the Federal cause from decisive defeat. There was no army to protect Washington but the body of troops under his command; these were largely raw levies, which defeat would have broken to pieces, and thus the way would have been open for Lee's march upon Washington or toward Philadelphia—a movement whose probable result would have been a treaty of peace and the independence of the Southern Confederacy. All these hopes were reversed by McClellan's rapid march and prompt attack. In the hours of a single autumn day, on the banks of the Antietam, the triumphant advance of the Confederates was checked and defeated. And, if the further fact be considered that the adversary thus checkmated was Lee, the military ability of General McClellan must be conceded. It is the fashion, it would appear, in some quarters, to deny him this quality. History will decide.

The merit of Lee was equally conspicuous, and his partial failure in the campaign was due to circumstances over which he had no control. His plan, as was always the case with him, was deep-laid, and every contingency had been provided for. He was disappointed in his aim by three causes which he could not foresee. One was the great diminution of his force, owing to the rapidity of his march, and the incessant fighting; another, the failure in obtaining recruits in Maryland; and a third, the discovery by General McClellan of the "lost dispatch," as it is called, which revealed Lee's whole plan to his adversary. In consequence of the "finding" of the order of march, McClellan advanced with such rapidity that the laggards of the Southern army on the hills north of Leesburg had no opportunity of joining the main body. The gaps in the ranks of the army thus made were not filled up by Maryland recruits; Lee fell back, and his adversary followed, no longer fearful of advancing too quickly; Jackson had no time after reducing Harper's Ferry to rejoin Lee at Hagerstown; thus concentration of his troops, and a battle somewhere near Sharpsburg, were rendered a necessity with General Lee.

In this tissue of adverse events, the discovery of the order of march by General McClellan occupies a very prominent place. This incident resembles what the French call a fatality. Who was to blame for the circumstance still remains a mystery; but it may be said with entire certainty that the brave officer upon whom it was charged was entirely guiltless of all fault in the matter.

[Footnote: The officer here referred to is General D.H. Hill. General McClellan said in his testimony afterward, before the congressional committee: "When at Frederick, we found the original order issued to D.H. Hill," etc. The inference was thus a natural one that General Hill was to blame, but that officer has proved clearly that he had nothing to do with the affair. He received but one copy of the order, which was handed to him by General Jackson in person, and, knowing its great importance, he placed it in his pocket-book, and still retains it in his possession. This fact is conclusive, since General Hill could not have "lost" what he continues to hold in his hands. This mystery will be cleared up at some time, probably; at present, but one thing is certain, that General Hill was in no manner to blame. The present writer desires to make this statement as explicit as possible, as, in other accounts of these transactions, he was led by General McClellan's language to attribute blame to General Hill where he deserved none.]

Whatever may have been the secret history of the "lost dispatch," however, it certainly fell into General McClellan's hands, and largely directed the subsequent movements of the opposing armies.
