Waddy Thompson, United States Minister to Mexico, to Abel P. Upshur, Secretary of State of the United States


No. 31 Mexico, October 29, 1843.

Sir: I have the happiness to inform you that I have a fair prospect to conclude the convention with this Govt in the course of this week. When I do I shall send it immediately to you. All the important features of the project, which you sent me, will be retained, and the few alterations, which I shall have to make, I am sure you will be satisfied with. It is alone owing to the apprehension of collision with England that I shall have been able to accomplish this. In the event of such collision, am I to interpose officially my good offices. . . .

I am entirely satisfied that the communication to me on the subject of the annexation of Texas was solely intended for political effect, here and to operate on the approaching elections. I think that there has been a manifest change in the feelings of the Mexican people and government towards us; and that they really desire to maintain friendly relations with us, which it is so much their interest to do. . . .

The elections have resulted in favor of Prest Santa Anna, which in effect secures his continuance in power for life. I am not sure that it is not the best thing that can happen for Mexico herself. I am sure that it is so for all foreign nations having intercourse with Mexico. No other man in the country has the energy and the prestige, which are necessary to govern it. I regard it as adding to the value of the claims of our citizens, and securing their payment. If he had the nerve to order the forced loan for the first payment, he will not be apt to fail in the others. Indeed he requested me in my last interview with him to assure the President that all the payments would be punctually made. . . .

Recurring to the history of the past we find that Spain, before the revolution adopted the policy of peopling Texas with colonists. The object, as the undersigned believes was to bring thither a population, which would put a stop to the ravages of the hostile indians. After the revolution the Mexican United States by a law of the State of Coahuila and Texas, enacted March 24. 1825, adopted and continued the same policy. The colonists, who embraced the invitation thus held out, were principally natives of the U. S. and the north of Europe.

The disturbances, which soon afterwards took place in Texas, could not fail to attract the attention of the Govt of the U. S., which soon foresaw what, in the natural course of things, would be the result; and so early as the 15th March 1827, warned Mexico of the collisions which would inevitably ensue. On the 25 Augt 1829, it again called the attention of the Mexican Govt to the fact, that most of the grants, which, had been made in Texas, were already in the hands of Americans and Europeans; to the want of confidence and reciprocal attachment between the Mexican Govt and the inhabitants of Texas; to the fact that this want of confidence had in the short space of five years displayed itself in no less than four revolts, one of them having for its avowed object the independence of the country; to the hazard of dismemberment, to which the extensive confederacy of Mexico was exposed by the frequent revolutions, to which she was subject; and finally to the probability that the first successful blow would be struck in Texas.—

Thus the Govt of the U. S., so far from being responsible for any of the circumstances, which led to the revolution of Texas, so early as 1827, pointed out to Mexico the results likely to ensue as the natural and necessary consequences of her own policy, and forewarned her of her danger.

The result has verified the prediction. Texas, having the example of Mexico and the U. S. before her eyes, declared her right to govern herself, as was to have been expected. She declared her independence, and successfully repelled the army sent to subdue her. She effectually sustained by force of arms the right, which she claimed, and having shown her ability to realize and establish as a fact the abstract right to independence, which she asserts, the world admits and Mexico, who set her an example, ought not to deny, she was received into the society of sovereign and independent nations.

As a sovereign and independent nation she applied for the benefit of admission into the American Union. This was at first refused her, perhaps owing to that regard, with which the Govt of the U. S. has always treated Mexico. The U. S. have now waited eight years for Mexico to reconquer Texas. She has not done so, nor attempted it; and it is now proposed to grant to Texas the admission into the American Union, which she desires.

But Mexico claims that she has a right to reconquer Texas, and that the U. S. have therefore mo right to consider Texas as a sovereign state. The undersigned by no means admits the deduction. The U. S. admitted the right of Spain to reconquer Mexico; but long before Spain relinquished this right, the U. S. not only treated with Mexico, as sovereign both de jure and de facto, but proposed also to purchase of her this very portion of territory, over which Spain then asserted the same rights that Mexico now does. They did so in 1827, and in 1829, on the very eve of a Spanish invasion—
