Jefferson Davis is a born soldier. Even if we could forget the glories of the assault upon Teneria and El Diablo, and banish the thrilling recollection of that movement at Buena Vista, the genius, novelty, and intrepidity of which electrified the world of military science, and extorted the enthusiastic admiration of the victor of Waterloo, we must yet recognize the impress of those rare gifts and graces which are the titles to authority. The erect yet easy carriage, the true martial dignity of bearing, which is altogether removed from the supercilious _hauteur_ of the mere martinet, the almost fascinating expression of _suaviter in modo_, which yet does not for an instant conceal the _fortiter in re_, constitute in him that imperial semblance, to which the mind involuntarily concedes the right to supreme command. It is impossible, in the presence of Mr. Davis, to deny this recognition of his intuitive soldiership. Not only is obvious to the eye the commanding mien of the soldier, but the order, the discipline of the educated soldier, whose nature, stern and unflinching, was yet plastic to receive the impressions of an art with which it felt an intuitive alliance. This military precision is characteristic of Mr. Davis in every aspect in which he appears. There is the constant fixedness of gaze upon the object to be reached, and the cautious calculation of the chances of success with the means and forces ready at hand; a constant regard for bases of supply and a proper concern for lines of retreat, and, above all, the prompt and vigorous execution, if success be practicable and the attack determined upon. Even in his oratory and statesmanship are these characteristics evinced. In the former there is far more of rhetorical order, harmony, and symmetry, than of rhetorical ornament and display; and in the latter there is purpose, consistency, and method, with little regard for the shifts of expediency and the suggestions of hap-hazard temerity. The attachment of Mr. Davis for the profession of arms is little less than a passion--an inspiration. True, he voluntarily abandoned the army, at an age when military life is most attractive to men, but the field of politics was far more inviting to a commendable aspiration for fame, than the army at a season of profound peace. But a more potent consideration, of a domestic nature, urged his withdrawal from military life. He was about to be married, and preferred not to remain in the army after having assumed the responsibilities of that relation. His speeches in the House of Representatives, indicating his earnest interest in military affairs, his solicitude in behalf of the army, his enthusiastic championship of the Military Academy, and his thorough information respecting all subjects pertaining to the military interests of the country, show his ambitious and absorbing study of his favorite science.
