[Illustration: The Charge of Colonel Davis' Regiment at Buena Vista]
With flying banners and sounding trumpets the gailey caparisoned lancers came down at a thundering gallop until a sheet of flame from the angle wrapped their front ranks and bore it down to destruction. Quickly recovering, the survivors, with the fury of madmen, threw themselves again and again upon those stubborn ranks, which, now assailed on two sides, refused to give an inch, and met every onslaught with a withering fire, which soon so cumbered the ground with the dead that it was with difficulty the living could move over it.
At last utterly demoralized by the awful carnage, the Mexican lines broke and fled from the field. The day was over. Buena Vista was won, and Colonel Davis had accomplished a feat which, when Sir Colin Campbell imitated it at Inkerman two years later, he was sent by England to retrieve her fallen fortunes in India.
Notwithstanding the fact that Colonel Davis' right foot had been shattered early in the morning, he had refused to leave the field for aid, but now at the close of the action he fell fainting from his horse. The wound was a dangerous one, and as the surgeons were of the opinion that more than a year must elapse before he could hope to walk, as soon as he was able to travel, General Taylor insisted on his going home, and thus closed his career in the Mexican War.
This exploit at Buena Vista created the profoundest enthusiasm throughout the country, and the Legislatures of several states passed resolutions thanking him for his services. Governor Brown of his own state, in obedience to an overwhelming popular sentiment, a few weeks after his return, appointed Colonel Davis to fill a vacancy that had occurred in the Senate--an appointment which was speedily ratified by the Legislature.
When, in 1847, Mr. Davis took his seat in the Senate, that irrepressible conflict, inevitable from the hour that the Constitutional Convention of 1787 sanctioned slavery as an institution within the United States, had reached a crisis which was threatening the very existence of the Union. The Missouri Compromise prohibiting slavery north of 36° 30' had failed to sanction it in express terms south of that parallel, and while in 1820 probably no one would have denied that this was the logical and obvious meaning of that measure, such was not the case thirty years later. The Abolitionists had opposed the annexation of Texas, believing, as Mr. Adams declared, that such an event would justify the dissolution of the Union.
