We now approached General McClellan's head-quarters, which, at that time, were established at Fairfield Seminary. The edifice was situated on a gentle elevation, amid very agreeable scenery, and, at a distance, looked like a gentleman's seat. Preparations were going forward for reviewing a division of ten or twelve thousand men, the various regiments composing which had begun to array themselves on an extensive plain, where, methought, there was a more convenient place for a battle than is usually found in this broken and difficult country. Two thousand cavalry made a portion of the troops to be reviewed. By-and-by we saw a pretty numerous troop of mounted officers, who were congregated on a distant part of the plain, and whom we finally ascertained to be the Commander-in-Chief's staff, with McClellan himself at their head. Our party managed to establish itself in a position conveniently close to the General, to whom, moreover, we had the honor of an introduction; and he bowed, on his horseback, with a good deal of dignity and martial courtesy, but no airs nor fuss nor pretension beyond what his character and rank inevitably gave him. Now, at that juncture, and, in fact, up to the present moment, there was, and is, a most fierce and bitter outcry, and detraction loud and low, against General McClellan, accusing him of sloth, imbecility, cowardice, treasonable purposes, and, in short, utterly denying his ability as a soldier, and questioning his integrity as a man. Nor was this to be wondered at; for when before, in all history, do we find a general in command of half a million of men, and in presence of an enemy inferior in numbers and no better disciplined than his own troops, leaving it still debatable, after the better part of a year, whether he is a soldier or no? The question would seem to answer itself in the very asking. Nevertheless, being most profoundly ignorant of the art of war, like the majority of the General's critics, and, on the other hand, having some considerable impressibility by men's characters, I was glad of the opportunity to look him in the face, and to feel whatever influence might reach me from his sphere. So I stared at him, as the phrase goes, with all the eyes I had; and the reader shall have the benefit of what I saw,--to which he is the more welcome, because, in writing this article, I feel disposed to be singularly frank, and can scarcely restrain myself from telling truths the utterance of which I should get slender thanks for.
