The Mexican Government well knew that both our national honor and the protection due to our citizens imperatively required that the two questions of boundary and indemnity should be treated of together, as naturally and inseparably blended, and they ought to have seen that this course was best calculated to enable the United States to extend to them the most liberal justice. On the 30th of December, 1845, General Herrera resigned the Presidency and yielded up the Government to General Paredes without a struggle. Thus a revolution was accomplished solely by the army commanded by Paredes, and the supreme power in Mexico passed into the hands of a military usurper who was known to be bitterly hostile to the United States. Although the prospect of a pacific adjustment with the new Government was unpromising from the known hostility of its head to the United States, yet, determined that nothing should be left undone on our part to restore friendly relations between the two countries, our minister was instructed to present his credentials to the new Government and ask to be accredited by it in the diplomatic character in which he had been commissioned. These instructions he executed by his note of the 1st of March, 1846, addressed to the Mexican minister of foreign affairs, but his request was insultingly refused by that minister in his answer of the 12th of the same month. No alternative remained for our minister but to demand his passports and return to the United States. Thus was the extraordinary spectacle presented to the civilized world of a Government, in violation of its own express agreement, having twice rejected a minister of peace invested with full powers to adjust all the existing differences between the two countries in a manner just and honorable to both. I am not aware that modern history presents a parallel case in which in time of peace one nation has refused even to hear propositions from another for terminating existing difficulties between them. Scarcely a hope of adjusting our difficulties, even at a remote day, or of preserving peace with Mexico, could be cherished while Paredes remained at the head of the Government. He had acquired the supreme power by a military revolution and upon the most solemn pledges to wage war against the United States and to reconquer Texas, which he claimed as a revolted province of Mexico. He had denounced as guilty of treason all those Mexicans who considered Texas as no longer constituting a part of the territory of Mexico and who were friendly to the cause of peace. The duration of the war which he waged against the United States was indefinite, because the end which he proposed of the reconquest of Texas was hopeless. Besides, there was good reason to believe from all his conduct that it was his intention to convert the Republic of Mexico into a monarchy and to call a foreign European prince to the throne. Preparatory to this end, he had during his short rule
