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. The time had arrived, in my opinion, when this Government was bound to exert its power to avenge and redress the wrongs of our citizens and to afford them protection in Mexico. The interposing obstacle was that the portion of the country under the sway of Miramon could not be reached without passing over territory under the jurisdiction of the constitutional Government. Under these circumstances I deemed it my duty to recommend to Congress in my last annual message the employment of a sufficient military force to penetrate into the interior, where the Government of Miramon was to be found, with or, if need be, without the consent of the Juarez Government, though it was not doubted that this consent could be obtained. Never have I had a clearer conviction on any subject than of the justice as well as wisdom of such a policy. No other alternative was left except the entire abandonment of our fellow-citizens who had gone to Mexico under the faith of treaties to the systematic injustice, cruelty, and oppression of Miramon's Government. Besides, it is almost certain that the simple authority to employ this force would of itself have accomplished all our objects without striking a single blow. The constitutional Government would then ere this have been established at the City of Mexico, and would have been ready and willing to the extent of its ability to do us justice.
