As there was no doubt that General Filisola would religiously comply, as far as concerned himself, the President and cabinet agreed that I should set off for Mexico, in order to fulfill the other engagements, and with that intent I embarked on board the schooner Invincible, which was to carry me to the port of Vera Cruz.  Unfortunately, however, some indiscreet persons raised a mob, which obliged the authorities to have me landed by force and brought back into strict captivity.  This incident has prevented me from going to Mexico, where I should otherwise have arrived early in last month; and in consequence of it the Government of that country, doubtless ignorant of what has occurred, has withdrawn the command of the army from General Filisola and has ordered his successor, General Urrea, to continue its operations, in obedience to which order that general is, according to the latest accounts, already at the river Nueces.  In vain have some reflecting and worthy men endeavored to demonstrate the necessity of moderation and of my going to Mexico according to the convention; but the excitement of the public mind has increased with the return of the Mexican army to Texas.  Such is the state of things here at present.  The continuation of the war and of its disasters is therefore inevitable unless the voice of reason be heard in proper time from the mouth of some powerful individual.  It appears to me that you, sir, have it in your power to perform this good office, by interfering in favor of the execution of the said convention, which shall be strictly fulfilled on my part.  When I offered to treat with this Government, I was convinced that it was useless for Mexico to continue the war.  I have acquired exact information respecting this country which I did not possess four months ago.  I have too much zeal for the interests of my country to wish for anything which is not compatible with them.  Being always ready to sacrifice myself for its glory and advantage, I never would have hesitated to subject myself to torments or death rather than consent to any compromise if Mexico could thereby have obtained the slightest benefit.  I am firmly convinced that it is proper to terminate this question by political negotiation.  That conviction alone determined me sincerely to agree to what has been stipulated, and in the same spirit I make to you this frank declaration.  Be pleased, sir, to favor me by a like confidence on your part.  Afford me the satisfaction of avoiding approaching evils and of contributing to that good which my heart advises.  Let us enter into negotiations by which the friendship between your nation and the Mexican may be strengthened, both being amicably engaged in giving being and stability to a people who are desirous of appearing in the political world, and who, under the protection of the two nations, will attain its object within a few years.

The Mexicans are magnanimous when treated with consideration.  I will clearly set before them the proper and humane reasons which require noble and frank conduct on their part, and I doubt not that they will act thus as soon as they have been convinced.
