Justin H. Smith - The Mexican-American War (Vol. 1&2)

At the beginning of March, 1845, our President signed the joint resolution of Congress which provided for the annexation of Texas. Almonte, the Mexican minister, at once protested, giving notice that his country would maintain the claim to her ancient province “at all times, by every means ... in her power”; and although James Buchanan, who now became secretary of state under Polk, replied in a conciliatory manner, Almonte broke off diplomatic relations and left our shores. At Mexico the news produced a tremendous commotion, heightened by the report from California that a revolution, decided by the American settlers, had occurred in that department. War at once and war to the knife! cried the press in concert; while the administration, in a note moderated by the British and French ministers yet sufficiently positive, severed official relations with Shannon, and insisted upon this policy even after receiving a conciliatory reply from him. By the action of Mexico there was, therefore, a complete rupture between the two countries.8

When it was learned, about the middle of July, that our terms of annexation had been accepted by Texas, passion burst forth again. The leash of Mexican eloquence and fury broke. “August Houses! President of the Republic!” cried El Amigo del Pueblo, “The hour of danger for the country has sounded and she has a right to look to you for salvation. Union and war!” Not merely Texas but all Mexico, the people were told, had been marked as its prey by American greed. In order to save itself before the public the administration, though at heart averse to hostilities, proposed to Congress a declaration of war. Money was asked from the Chambers, and full quotas of troops were summoned from the departments; and by the end of the month, as the agent of our government duly reported, the course of things pointed strongly toward hostilities. The archives of Vera Cruz were carried to the interior; new guns were mounted in the fortress there; steps were taken to raise a loan of fifteen millions; munitions and provisions were said to be going as rapidly as possible to Matamoros; and much was heard about the movements of troops. At the end of July the ministers of Mexico at London and Paris were notified that an appeal to arms would be made. August 8 the Mexican consulate at New Orleans closed; and a few days later our consul at Havana reported that his Mexican colleague had received an official notification of the existence of war.9

To be sure, no public declaration to that effect appeared, but there were good reasons for considering this fact unimportant. With Spanish-American subtlety the Mexicans discovered that the threat of August 23, 1843, repeated later, had rendered such an announcement unnecessary, and that it would be shrewder to hold that by annexing Texas we had declared war upon them, since they would then be free to attack or defer attacking us, as might seem expedient. Besides, it was argued, Texas was merely a rebellious province, and hence Mexico could make war there at will, without giving us an excuse for opening hostilities against her seaboard, and without enabling us to seize territory by the right of belligerency. Consequently, as large forces had been ordered to the north, a move across the Rio Grande at any hour seemed more than possible; and the official journal urged, that it should be effected at the earliest practicable moment, in order to prevent the United States from occupying the territory, and making ready there for hostilities.10

The American government, on the other hand, undertook to restore friendly relations. The official assurances of good-will given Almonte were supplemented by private representations conveyed to him through a mutual friend by a member of our Cabinet; and Polk took also a step of much greater importance. Before the end of March W. S. Parrott was appointed a confidential agent of our state department, and ordered to reach Mexico, which had long been his place of residence, by the quickest route. Try to convince the Mexican government, ran his instructions, that it is truly for the interest of that country, “to restore friendly relations between the two republics.” If it is found willing, you may reveal your official character, and say that the United States will send a “Minister” on learning that he will be kindly received. The annexation of Texas cannot be undone; but “you are at liberty to state your confident belief that in regard to all unsettled questions, we are prepared to meet Mexico in a most liberal and friendly spirit.”11

Thus commissioned, Parrott sought his post without delay, renewed his acquaintance with members of the Mexican Congress, invited them frequently to lunch or dinner, and talked, no doubt in the spirit of his instructions, with all such influential persons as he could reach. In particular, as he reported, he was “very precise in stating, that the Government of the United States could never recognize in Mexico the right to claim an indemnity for the annexation of Texas to the American Union; but that, in a treaty of limits , for the sake of peace and good neighborhood, the United States would, no doubt, be disposed, as had been officially stated, to meet Mexico, in a negotiation, upon the most friendly and liberal terms.” No explanation could have been clearer.12

There were good reasons for anticipating a favorable result from this overture. President Herrera, connected by marriage with a leading American merchant at the capital, was an honest, reasonable and patriotic citizen; and, knowing that hostilities with the United States would at best involve many costly sacrifices, and would very likely throw California into our hands, he desired to escape by some method from his public action in favor of war. It was altogether possible, too, that a reverse on the field might upset his administration and injure his friends; and, since the movement that had placed him in power had cost money, his backers, in order to be repaid, felt anxious to curtail instead of increasing the military expenses. Moreover there was trouble with both England and France at this time; the more intelligent part of the nation, cooling a little, were beginning to perceive the advantages of a peaceful settlement with us; a chance could be seen that in the end such a policy, reducing the cost of government, would become popular; and finally it was realized that unless money to pay the troops were obtained from the United States, their fickle allegiance probably could not be retained. Accordingly on August 29, 1845, Parrott reported that in his opinion an envoy from this country would be heartily welcomed; almost at the same time Black, our consul at Mexico, and Dimond, our consul at Vera Cruz, expressed the same view; and private advices tended to confirm these opinions.13

Our own reasons for wishing to have diplomatic intercourse restored were almost equal in strength to Herrera’s. Aside from the political and commercial interests that had always led us to seek the friendship of Mexico, we desired to collect the unpaid instalments of our awards, prosecute our claims, guard our citizens residing in that country, adjust the Texan difficulty, counteract prejudicial movements on the part of European states, and cultivate the good-will of the Central and South American peoples, who were sure to be influenced by the sentiments of their kindred next us. In particular, only two or three months later Guizot’s idea of establishing a balance of power in this hemisphere was exciting alarm in Congress; and there is reason to believe that our Executive, already aware of it, desired the support of Mexico in opposing a design so un-American. Besides, Polk felt sure that European governments had an eye upon California, and a minister was needed at the Mexican capital to prevent, if possible, any bargaining on the subject.14
