The wrongs which we have suffered from Mexico almost ever since she became an independent power and the patient endurance with which we have borne them are without a parallel in the history of modern civilized nations. There is reason to believe that if these wrongs had been resented and resisted in the first instance the present war might have been avoided. One outrage, however, permitted to pass with impunity almost necessarily encouraged the perpetration of another, until at last Mexico seemed to attribute to weakness and indecision on our part a forbearance which was the offspring of magnanimity and of a sincere desire to preserve friendly relations with a sister republic.
Scarcely had Mexico achieved her independence, which the United States were the first among the nations to acknowledge, when she commenced the system of insult and spoliation which she has ever since pursued. Our citizens engaged in lawful commerce were imprisoned, their vessels seized, and our flag insulted in her ports. If money was wanted, the lawless seizure and confiscation of our merchant vessels and their cargoes was a ready resource, and if to accomplish their purposes it became necessary to imprison the owners, captains, and crews, it was done. Rulers superseded rulers in Mexico in rapid succession, but still there was no change in this system of depredation. The Government of the United States made repeated reclamations on behalf of its citizens, but these were answered by the perpetration of new outrages.
