In conformity with this stipulation, a third convention was concluded and signed at the city of Mexico on the 20th of November, 1843, by the plenipotentiaries of the two Governments, by which provision was made for ascertaining and paying these claims. In January, 1844, this convention was ratified by the Senate of the United States with two amendments, which were manifestly reasonable in their character. Upon a reference of the amendments proposed to the Government of Mexico, the same evasions, difficulties, and delays were interposed which have so long marked the policy of that Government toward the United States. It has not even yet decided whether it would or would not accede to them, although the subject has been repeatedly pressed upon its consideration. Mexico has thus violated a second time the faith of treaties by failing or refusing to carry into effect the sixth article of the convention of January, 1843.
Such is the history of the wrongs which we have suffered and patiently endured from Mexico through a long series of years. So far from affording reasonable satisfaction for the injuries and insults we had borne, a great aggravation of them consists in the fact that while the United States, anxious to preserve a good understanding with Mexico, have been constantly but vainly employed in seeking redress for past wrongs, new outrages were constantly occurring, which have continued to increase our causes of complaint and to swell the amount of our demands. While the citizens of the United States were conducting a lawful commerce with Mexico under the guaranty of a treaty of “amity, commerce, and navigation,” many of them have suffered all the injuries which would have resulted from open war. This treaty, instead of affording protection to our citizens, has been the means of inviting them into the ports of Mexico that they might be, as they have been in numerous instances, plundered of their property and deprived of their personal liberty if they dared insist on their rights. Had the unlawful seizures of American property and the violation of the personal liberty of our citizens, to say nothing of the insults to our flag, which have occurred in the ports of Mexico taken place on the high seas, they would themselves long since have constituted a state of actual war between the two countries. In so long suffering Mexico to violate her most solemn treaty obligations, plunder our citizens of their property, and imprison their persons without affording them any redress we have failed to perform one of the first and highest duties which every government owes to its citizens, and the consequence has been that many of them have been reduced from a state of affluence to bankruptcy. The proud name of American citizen, which ought to protect all who bear it from insult and injury throughout the world, has afforded no such protection to our citizens in Mexico. We had ample cause of war against Mexico long before the breaking out of hostilities; but even then we forbore to take redress into our own hands until Mexico herself became the aggressor by invading our soil in hostile array and shedding the blood of our citizens.
Such are the grave causes of complaint on the part of the United States against Mexico--causes which existed long before the annexation of Texas to the American Union; and yet, animated by the love of peace and a magnanimous moderation, we did not adopt those measures of redress which under such circumstances are the justified resort of injured nations.
The annexation of Texas to the United States constituted no just cause of offense to Mexico. The pretext that it did so is wholly inconsistent and irreconcilable with well-authenticated facts connected with the revolution by which Texas became independent of Mexico. That this may be the more manifest, it may be proper to advert to the causes and to the history of the principal events of that revolution.
Texas constituted a portion of the ancient Province of Louisiana, ceded to the United States by France in the year 1803. In the year 1819 the United States, by the Florida treaty, ceded to Spain all that part of Louisiana within the present limits of Texas, and Mexico, by the revolution which separated her from Spain and rendered her an independent nation, succeeded to the rights of the mother country over this territory. In the year 1824 Mexico established a federal constitution, under which the Mexican Republic was composed of a number of sovereign States confederated together in a federal union similar to our own. Each of these States had its own executive, legislature, and judiciary, and for all except federal purposes was as independent of the General Government and that of the other States as is Pennsylvania or Virginia under our Constitution. Texas and Coahuila united and formed one of these Mexican States. The State constitution which they adopted, and which was approved by the Mexican Confederacy, asserted that they were “free and independent of the other Mexican United States and of every other power and dominion whatsoever,” and proclaimed the great principle of human liberty that “the sovereignty of the state resides originally and essentially in the general mass of the individuals who compose it.” To the Government under this constitution, as well as to that under the federal constitution, the people of Texas owed allegiance.
Emigrants from foreign countries, including the United States, were invited by the colonization laws of the State and of the Federal Government to settle in Texas. Advantageous terms were offered to induce them to leave their own country and become Mexican citizens. This invitation was accepted by many of our citizens in the full faith that in their new home they would be governed by laws enacted by representatives elected by themselves, and that their lives, liberty, and property would be protected by constitutional guaranties similar to those which existed in the Republic they had left. Under a Government thus organized they continued until the year 1835, when a military revolution broke out in the City of Mexico which entirely subverted the federal and State constitutions and placed a military dictator at the head of the Government. By a sweeping decree of a Congress subservient to the will of the Dictator the several State constitutions were abolished and the States themselves converted into mere departments of the central Government. The people of Texas were unwilling to submit to this usurpation. Resistance to such tyranny became a high duty. Texas was fully absolved from all allegiance to the central Government of Mexico from the moment that Government had abolished her State constitution and in its place substituted an arbitrary and despotic central government. Such were the principal causes of the Texan revolution. The people of Texas at once determined upon resistance and flew to arms. In the midst of these important and exciting events, however, they did not omit to place their liberties upon a secure and permanent foundation. They elected members to a convention, who in the month of March, 1836, issued a formal declaration that their “political connection with the Mexican nation has forever ended, and that the people of Texas do now constitute a free, sovereign, and independent Republic, and are fully invested with all the rights and attributes which properly belong to independent nations.” They also adopted for their government a liberal republican constitution. About the same time Santa Anna, then the Dictator of Mexico, invaded Texas with a numerous army for the purpose of subduing her people and enforcing obedience to his arbitrary and despotic Government. On the 21st of April, 1836, he was met by the Texan citizen soldiers, and on that day was achieved by them the memorable victory of San Jacinto, by which they conquered their independence. Considering the numbers engaged on the respective sides, history does not record a more brilliant achievement. Santa Anna himself was among the captives.
In the month of May, 1836, Santa Anna acknowledged by a treaty with the Texan authorities in the most solemn form “the full, entire, and perfect independence of the Republic of Texas.” It is true he was then a prisoner of war, but it is equally true that he had failed to reconquer Texas, and had met with signal defeat; that his authority had not been revoked, and that by virtue of this treaty he obtained his personal release. By it hostilities were suspended, and the army which had invaded Texas under his command returned in pursuance of this arrangement unmolested to Mexico.
From the day that the battle of San Jacinto was fought until the present hour Mexico has never possessed the power to reconquer Texas. In the language of the Secretary of State of the United States in a dispatch to our minister in Mexico under date of the 8th of July, 1842--
Mexico may have chosen to consider, and may still choose to consider, Texas as having been at all times since 1835, and as still continuing, a rebellious province; but the world has been obliged to take a very different view of the matter. From the time of the battle of San Jacinto, in April, 1836, to the present moment, Texas has exhibited the same external signs of national independence as Mexico herself, and with quite as much stability of government. Practically free and independent, acknowledged as a political sovereignty by the principal powers of the world, no hostile foot finding rest within her territory for six or seven years, and Mexico herself refraining for all that period from any further attempt to reestablish her own authority over that territory, it can not but be surprising to find Mr. De Bocanegra the secretary of foreign affairs of Mexico complaining that for that whole period citizens of the United States or its Government have been favoring the rebels of Texas and supplying them with vessels, ammunition, and money, as if the war for the reduction of the Province of Texas had been constantly prosecuted by Mexico, and her success prevented by these influences from abroad.
In the same dispatch the Secretary of State affirms that--
