About this period the Indians, on various portions of the frontier, stimulated by dissatisfaction with the course of the Government concerning certain claims and guarantees, which had been accorded them in previous treaties, were excessively annoying, and the Government was forced to resort to energetic military measures to suppress them. Lieutenant Davis had ample opportunity for the exhibition of his high soldierly qualities, cool courage, and admirable self-possession, in the Black Hawk war, during which he was frequently employed in duties of an important and dangerous character. During the captivity of Black Hawk, that famous Indian chieftain and warrior is said to have conceived a very strong attachment for Lieutenant Davis, whose gallantry and pleasing amenities of bearing greatly impressed the captive enemy. After his transfer to the dragoons, Lieutenant Davis saw two years of very active service in the various expeditions against the Pawnees, Camanches, and other Indian tribes, and accompanied the first expedition which successfully penetrated the strongholds of the savages, and conquered a peace by reducing them to subjection. Though attached to the profession of arms, for which he has on repeated occasions, during his subsequent life, evinced an almost passionate fondness and a most unusual aptitude, Lieutenant Davis resigned his commission in June, 1835, and returning to Mississippi devoted his attention to the cultivation of cotton and to the assiduous pursuit of letters. Not long after his resignation, he had married the daughter of Col. Zachary Taylor, under whose eye he was destined, in a few years, to win such immortal renown upon the fields of Mexico. Living upon his plantation in great seclusion, he devoted himself with zeal and enthusiasm to those studies which were to qualify him for the eminent position in politics and statesmanship which he had resolved to assume. In that retirement were sown the seed, whose abundant fruits were seen in those splendid specimens of senatorial and popular eloquence, at once models of taste and exhibitions of intellectual power; in the pure, terse, and elegant English of his matchless state papers, which will forever be the delight of scholars and the study of statesmen, and in that elevated and enlightened statesmanship, which scorning the low ambition of demagogues and striving always for the ends of patriotism and principle, illumines, for more than a score of years, the legislative history of the Union.
