It was during the term of President John Tyler, who succeeded to the chief magistracy after poor worn-out old General Harrison had exercised its functions for one brief month, that the events took their rise which ripened into the War with Mexico. The large territory of Texas, lying upon our extreme southwestern border, between Louisiana and Mexico, had revolted from the latter nation and set up an independent republic of its own. Texas had been largely colonized from the slave States, and General Sam Houston, formerly of Tennessee, was its President.
Election of Polk.
The republic sought admission to our Union in 1837, but the application was then refused. Seven years later, Mr. Tyler gave it a more hospitable reception. A treaty was framed, and at first rejected by the United States Senate. At last, in March, 1845, just as Mr. Tyler was retiring from office, a resolution was adopted by both houses of Congress annexing Texas, and this resolution was approved by the outgoing President. The presidential campaign in the autumn of 1844, between Henry Clay as the Whig and James K. Polk as the Democratic candidate, was fought mainly upon the issue of this annexation, and the election of Mr. Polk was looked upon as a confirmation of it by the people.
Boundary Dispute.
No sooner had the new President been inaugurated than what the Whig leaders had earnestly predicted came to pass. A dispute arose with Mexico as to the boundary between that country and Texas. Mexico claimed that this boundary was the river Nueces; Texas asserted it to be the Rio Grande. The matter was one of some importance, as the Nueces is a hundred miles northeastward from the Rio Grande, and that much of territory was therefore in dispute. The brief negotiations which ensued with a view to the settlement of this question, proved abortive. President Polk accordingly ordered General Zachary Taylor to occupy the disputed territory with a small body of troops. Taylor concentrated his men at Corpus Christi, near the frontier.
First Battles.
The Mexicans were equally prompt, and the first collisions occurred at Palo Alto and Resaca de la Palma, near the Rio Grande. General Taylor repulsed the enemy with little difficulty and but small loss, and, crossing the Rio Grande, advanced upon and captured Matamoras. Thus far the hostilities had proceeded when a formal declaration of war was made against Mexico by the United States. Clay and the Whigs strenuously opposed this action; but the administration party bore down all opposition. Volunteers now flocked, especially from the Southern States, to Taylor's standard; and in a few weeks he found himself at the head of a resolute though not very well disciplined force of nearly eight thousand men. Monterey, a fortified town of considerable importance, was held by about nine thousand Mexican troops. General Taylor's objective point was the City of Mexico.
Taylor's Campaign.
After an attack of three days, Monterey fell into his hands. Victory followed his army everywhere. Santa Anna, a crafty and able man, who had sat in the presidential chair of Mexico, was now in command of the Mexican army, and confronted Taylor at Huena Vista. His gallant attempt to stay the advance of the triumphant Americans, however, failed, for Taylor defeated him in what was perhaps the most brilliantly and hotly contested action of the war. Taylor's force at Buena Vista numbered about six thousand men, the larger part of them being but rudely disciplined soldiers. Santa Anna's command comprised at least twenty thousand Mexicans. It was at Buena Vista that the Lancers, the best body of troops in the Mexican army, were routed by the dashing onset of the American volunteers.
