Committees of both Houses of Congress, to which this message of the President was referred, fully sustained his views of the character of the wrongs which we had suffered from Mexico, and recommended that another demand for redress should be made before authorizing war or reprisals. The Committee on Foreign Relations of the Senate, in their report, say:
After such a demand, should prompt justice be refused by the Mexican Government, we may appeal to all nations, not only for the equity and moderation with which we shall have acted toward a sister republic, but for the necessity which will then compel us to seek redress for our wrongs, either by actual war or by reprisals. The subject will then be presented before Congress, at the commencement of the next session, in a clear and distinct form, and the committee can not doubt but that such measures will be immediately adopted as may be necessary to vindicate the honor of the country and insure ample reparation to our injured fellow-citizens.
The Committee on Foreign Affairs of the House of Representatives made a similar recommendation. In their report they say that—
They fully concur with the President that ample cause exists for taking redress into our own hands, and believe that we should be justified in the opinion of other nations for taking such a step. But they are willing to try the experiment of another demand, made in the most solemn form, upon the justice of the Mexican Government before any further proceedings are adopted.
No difference of opinion upon the subject is believed to have existed in Congress at that time; the executive and legislative departments concurred; and yet such has been our forbearance and desire to preserve peace with Mexico that the wrongs of which we then complained, and which gave rise to these solemn proceedings, not only remain unredressed to this day, but additional causes of complaint of an aggravated character have ever since been accumulating. Shortly after these proceedings a special messenger was dispatched to Mexico to make a final demand for redress, and on the 20th of July, 1837, the demand was made. The reply of the Mexican Government bears date on the 29th of the same month, and contains assurances of the “anxious wish” of the Mexican Government “not to delay the moment of that final and equitable adjustment which is to terminate the existing difficulties between the two Governments;” that “nothing should be left undone which may contribute to the most speedy and equitable determination of the subjects which have so seriously engaged the attention of the American Government;” that the “Mexican Government would adopt as the only guides for its conduct the plainest principles of public right, the sacred obligations imposed by international law, and the religious faith of treaties,” and that “whatever reason and justice may dictate respecting each case will be done.” The assurance was further given that the decision of the Mexican Government upon each cause of complaint for which redress had been demanded should be communicated to the Government of the United States by the Mexican minister at Washington.
