POLITICAL INTRIGUE--BUENA VISTA--MOVEMENT AGAINST VERA CRUZ--SIEGE AND CAPTURE OF VERA CRUZ.
The Mexican war was a political war, and the administration conducting it desired to make party capital out of it. General Scott was at the head of the army, and, being a soldier of acknowledged professional capacity, his claim to the command of the forces in the field was almost indisputable and does not seem to have been denied by President Polk, or Marcy, his Secretary of War. Scott was a Whig and the administration was democratic. General Scott was also known to have political aspirations, and nothing so popularizes a candidate for high civil positions as military victories. It would not do therefore to give him command of the "army of conquest." The plans submitted by Scott for a campaign in Mexico were disapproved by the administration, and he replied, in a tone possibly a little disrespectful, to the effect that, if a soldier's plans were not to be supported by the administration, success could not be expected. This was on the 27th of May, 1846. Four days later General Scott was notified that he need not go to Mexico. General Gaines was next in rank, but he was too old and feeble to take the field. Colonel Zachary Taylor--a brigadier-general by brevet--was therefore left in command. He, too, was a Whig, but was not supposed to entertain any political ambitions; nor did he; but after the fall of Monterey, his third battle and third complete victory, the Whig papers at home began to speak of him as the candidate of their party for the Presidency. Something had to be done to neutralize his growing popularity. He could not be relieved from duty in the field where all his battles had been victories: the design would have been too transparent. It was finally decided to send General Scott to Mexico in chief command, and to authorize him to carry out his own original plan: that is, capture Vera Cruz and march upon the capital of the country. It was no doubt supposed that Scott's ambition would lead him to slaughter Taylor or destroy his chances for the Presidency, and yet it was hoped that he would not make sufficient capital himself to secure the prize.
The administration had indeed a most embarrassing problem to solve. It was engaged in a war of conquest which must be carried to a successful issue, or the political object would be unattained. Yet all the capable officers of the requisite rank belonged to the opposition, and the man selected for his lack of political ambition had himself become a prominent candidate for the Presidency. It was necessary to destroy his chances promptly. The problem was to do this without the loss of conquest and without permitting another general of the same political party to acquire like popularity. The fact is, the administration of Mr. Polk made every preparation to disgrace Scott, or, to speak more correctly, to drive him to such desperation that he would disgrace himself.
General Scott had opposed conquest by the way of the Rio Grande, Matamoras and Saltillo from the first. Now that he was in command of all the forces in Mexico, he withdrew from Taylor most of his regular troops and left him only enough volunteers, as he thought, to hold the line then in possession of the invading army. Indeed Scott did not deem it important to hold anything beyond the Rio Grande, and authorized Taylor to fall back to that line if he chose. General Taylor protested against the depletion of his army, and his subsequent movement upon Buena Vista would indicate that he did not share the views of his chief in regard to the unimportance of conquest beyond the Rio Grande.
Scott had estimated the men and material that would be required to capture Vera Cruz and to march on the capital of the country, two hundred and sixty miles in the interior. He was promised all he asked and seemed to have not only the confidence of the President, but his sincere good wishes. The promises were all broken. Only about half the troops were furnished that had been pledged, other war material was withheld and Scott had scarcely started for Mexico before the President undertook to supersede him by the appointment of Senator Thomas H. Benton as lieutenant-general. This being refused by Congress, the President asked legislative authority to place a junior over a senior of the same grade, with the view of appointing Benton to the rank of major-general and then placing him in command of the army, but Congress failed to accede to this proposition as well, and Scott remained in command: but every general appointed to serve under him was politically opposed to the chief, and several were personally hostile.
General Scott reached Brazos Santiago or Point Isabel, at the mouth of the Rio Grande, late in December, 1846, and proceeded at once up the river to Camargo, where he had written General Taylor to meet him. Taylor, however, had gone to, or towards Tampico, for the purpose of establishing a post there. He had started on this march before he was aware of General Scott being in the country. Under these circumstances Scott had to issue his orders designating the troops to be withdrawn from Taylor, without the personal consultation he had expected to hold with his subordinate.
General Taylor's victory at Buena Vista, February 22d, 23d, and 24th, 1847, with an army composed almost entirely of volunteers who had not been in battle before, and over a vastly superior force numerically, made his nomination for the Presidency by the Whigs a foregone conclusion. He was nominated and elected in 1848. I believe that he sincerely regretted this turn in his fortunes, preferring the peace afforded by a quiet life free from abuse to the honor of filling the highest office in the gift of any people, the Presidency of the United States.
