JAMES K. POLK.

WASHINGTON, May 11, 1846.

To the Senate and House of Representatives:

The existing state of the relations between the United States and Mexico renders it proper that I should bring the subject to the consideration of Congress. In my message at the commencement of your present session the state of these relations, the causes which led to the suspension of diplomatic intercourse between the two countries in March, 1845, and the long-continued and unredressed wrongs and injuries committed by the Mexican Government on citizens of the United States in their persons and property were briefly set forth.

As the facts and opinions which were then laid before you were carefully considered, I can not better express my present convictions of the condition of affairs up to that time than by referring you to that communication.

The strong desire to establish peace with Mexico on liberal and honorable terms, and the readiness of this Government to regulate and adjust our boundary and other causes of difference with that power on such fair and equitable principles as would lead to permanent relations of the most friendly nature, induced me in September last to seek the reopening of diplomatic relations between the two countries. Every measure adopted on our part had for its object the furtherance of these desired results. In communicating to Congress a succinct statement of the injuries which we had suffered from Mexico, and which have been accumulating during a period of more than twenty years, every expression that could tend to inflame the people of Mexico or defeat or delay a pacific result was carefully avoided. An envoy of the United States repaired to Mexico with full powers to adjust every existing difference. But though present on the Mexican soil by agreement between the two Governments, invested with full powers, and bearing evidence of the most friendly dispositions, his mission has been unavailing. The Mexican Government not only refused to receive him or listen to his propositions, but after a long-continued series of menaces have at last invaded our territory and shed the blood of our fellow-citizens on our own soil.

It now becomes my duty to state more in detail the origin, progress, and failure of that mission. In pursuance of the instructions given in September last, an inquiry was made on the 13th of October, 1845, in the most friendly terms, through our consul in Mexico, of the minister for foreign affairs, whether the Mexican Government "would receive an envoy from the United States intrusted with full powers to adjust all the questions in dispute between the two Governments," with the assurance that "should the answer be in the affirmative such an envoy would be immediately dispatched to Mexico." The Mexican minister on the 15th of October gave an affirmative answer to this inquiry, requesting at the same time that our naval force at Vera Cruz might be withdrawn, lest its continued presence might assume the appearance of menace and coercion pending the negotiations. This force was immediately withdrawn. On the 10th of November, 1845, Mr. John Slidell, of Louisiana, was commissioned by me as envoy extraordinary and minister plenipotentiary of the United States to Mexico, and was intrusted with full powers to adjust both the questions of the Texas boundary and of indemnification to our citizens. The redress of the wrongs of our citizens naturally and inseparably blended itself with the question of boundary. The settlement of the one question in any correct view of the subject involves that of the other. I could not for a moment entertain the idea that the claims of our much-injured and long-suffering citizens, many of which had existed for more than twenty years, should be postponed or separated from the settlement of the boundary question.

Mr. Slidell arrived at Vera Cruz on the 30th of November, and was courteously received by the authorities of that city. But the Government of General Herrera was then tottering to its fall. The revolutionary party had seized upon the Texas question to effect or hasten its overthrow. Its determination to restore friendly relations with the United States, and to receive our minister to negotiate for the settlement of this question, was violently assailed, and was made the great theme of denunciation against it. The Government of General Herrera, there is good reason to believe, was sincerely desirous to receive our minister; but it yielded to the storm raised by its enemies, and on the 21st of December refused to accredit Mr. Slidell upon the most frivolous pretexts. These are so fully and ably exposed in the note of Mr. Slidell of the 24th of December last to the Mexican minister of foreign relations, herewith transmitted, that I deem it unnecessary to enter into further detail on this portion of the subject.

Five days after the date of Mr. Slidell's note General Herrera yielded the Government to General Paredes without a struggle, and on the 30th of December resigned the Presidency. This revolution was accomplished solely by the army, the people having taken little part in the contest; and thus the supreme power in Mexico passed into the hands of a military leader.

Determined to leave no effort untried to effect an amicable adjustment with Mexico, I directed Mr. Slidell to present his credentials to the Government of General Paredes and ask to be officially received by him. There would have been less ground for taking this step had General Paredes come into power by a regular constitutional succession. In that event his administration would have been considered but a mere constitutional continuance of the Government of General Herrera, and the refusal of the latter to receive our minister would have been deemed conclusive unless an intimation had been given by General Paredes of his desire to reverse the decision of his predecessor. But the Government of General Paredes owes its existence to a military revolution, by which the subsisting constitutional authorities had been subverted. The form of government was entirely changed, as well as all the high functionaries by whom it was administered.
