The clearest conception of the characters of Generals Sherman and Thomas is obtained by contrasting them. A correct estimate of General Grant may be had by forming in the imagination a character combining the peculiarities of both Sherman and Thomas; for in the person of the lieutenant general the very opposite qualities which distinguish the others meet and combine with singular grace and felicity. General Grant does not make so effective, or, so to speak, so dramatic a picture as Sherman, nor does he present so dignified, that is to say, so stately an appearance as Thomas; yet he combines in himself the originality and energy of the first, with the deliberation, coolness, and pertinacity of the latter. Without the constant fire and fury of Sherman, without the occasional sudden, fiery impulse of Thomas, Grant, always cool, calm, and dispassionate, is also always firm, always decided, and always progressive. Sherman is as mercurial as a Frenchman, and as demonstrative as an Italian; Thomas as phlegmatic as a Dutchman, and as tenacious as an Englishman; while Grant in every characteristic, in doggedness, pertinacity, positiveness, and taciturnity, is thoroughly American, and nothing else. Grant is a true sailor, in that he dreads both the storm of battle and the calm of inactivity, and his appropriate motto is "_In medio tutissimus ibis._" Thomas delights most in calm--is always calm himself, even in the midst of roughest seas. Sherman, on the contrary, delights in tempests, and would now be nothing if there had been no storm. Professor Mahan, who was the tutor of Grant and Sherman, has furnished a very handsome illustration of the contrast between them by comparing the first-named to a powerful low-pressure engine "which condenses its own steam and consumes its own smoke, and which pushes steadily forward and drives all obstacles before it," while Sherman belongs to the high-pressure class of engines, "which lets off both steam and smoke with a puff and a cloud, and dashes at its work with resistless vigor." Grant has Sherman's originality of mind, and, like him, gave expression to several new and striking thoughts upon the subject of the rebellion and its suppression, but they were invariably clothed in the full, rounded, and stately periods of Thomas rather than the sharp, curt, and nervous language of Sherman. He has planned several campaigns with not less of originality than that displayed by Sherman, but they have always been executed with the deliberation and persistence which is so prominent a characteristic of Thomas. Sherman has given us several splendid illustrations of strategy and logistics, as witness his marches in Mississippi, Georgia, and the Carolinas, but his battles will never be quoted as brilliant examples of grand tactics. Thomas has displayed abilities chiefly in the tactics of the battle-field, and has given us at Mill Spring and Nashville two splendid illustrations of the
