Our relations with Mexico remain in a most unsatisfactory condition. In my last two annual messages I discussed extensively the subject of these relations, and do not now propose to repeat at length the facts and arguments then presented. They proved conclusively that our citizens residing in Mexico and our merchants trading thereto had suffered a series of wrongs and outrages such as we have never patiently borne from any other nation. For these our successive ministers, invoking the faith of treaties, had in the name of their country persistently demanded redress and indemnification, but without the slightest effect. Indeed, so confident had the Mexican authorities become of our patient endurance that they universally believed they might commit these outrages upon American citizens with absolute impunity. Thus wrote our minister in 1856, and expressed the opinion that “nothing but a manifestation of the power of the Government and of its purpose to punish these wrongs will avail.”
Afterwards, in 1857, came the adoption of a new constitution for Mexico, the election of a President and Congress under its provisions, and the inauguration of the President. Within one short month, however, this President was expelled from the capital by a rebellion in the army, and the supreme power of the Republic was assigned to General Zuloaga. This usurper was in his turn soon compelled to retire and give place to General Miramon.
Under the constitution which had thus been adopted Senor Juarez, as chief justice of the supreme court, became the lawful President of the Republic, and it was for the maintenance of the constitution and his authority derived from it that the civil war commenced and still continues to be prosecuted.
Throughout the year 1858 the constitutional party grew stronger and stronger. In the previous history of Mexico a successful military revolution at the capital had almost universally been the signal for submission throughout the Republic. Not so on the present occasion. A majority of the citizens persistently sustained the constitutional Government. When this was recognized, in April, 1859, by the Government of the United States, its authority extended over a large majority of the Mexican States and people, including Vera Cruz and all the other important seaports of the Republic. From that period our commerce with Mexico began to revive, and the constitutional Government has afforded it all the protection in its power.
Meanwhile the Government of Miramon still held sway at the capital and over the surrounding country, and continued its outrages against the few American citizens who still had the courage to remain within its power. To cap the climax, after the battle of Tacubaya, in April, 1859, General Marquez ordered three citizens of the United States, two of them physicians, to be seized in the hospital at that place, taken out and shot, without crime and without trial. This was done, notwithstanding our unfortunate countrymen were at the moment engaged in the holy cause of affording relief to the soldiers of both parties who had been wounded in the battle, without making any distinction between them.
