Instead of this, however, we have been exerting our best efforts to propitiate her good will. Upon the pretext that Texas, a nation as independent as herself, thought proper to unite its destinies with our own, she has affected to believe that we have severed her rightful territory, and in official proclamations and manifestoes has repeatedly threatened to make war upon us for the purpose of reconquering Texas. In the meantime we have tried every effort at reconciliation. The cup of forbearance had been exhausted even before the recent information from the frontier of the Del Norte. But now, after reiterated menaces, Mexico has passed the boundary of the United States, has invaded our territory and shed American blood upon the American soil. She has proclaimed that hostilities have commenced, and that the two nations are now at war.
As war exists, and, notwithstanding all our efforts to avoid it, exists by the act of Mexico herself, we are called upon by every consideration of duty and patriotism to vindicate with decision the honor, the rights, and the interests of our country.
Anticipating the possibility of a crisis like that which has arrived, instructions were given in August last, "as a precautionary measure" against invasion or threatened invasion, authorizing General Taylor, if the emergency required, to accept volunteers, not from Texas only, but from the States of Louisiana, Alabama, Mississippi, Tennessee, and Kentucky, and corresponding letters were addressed to the respective governors of those States. These instructions were repeated, and in January last, soon after the incorporation of "Texas into our Union of States," General Taylor was further "authorized by the President to make a requisition upon the executive of that State for such of its militia force as may be needed to repel invasion or to secure the country against apprehended invasion." On the 2d day of March he was again reminded, "in the event of the approach of any considerable Mexican force, promptly and efficiently to use the authority with which he was clothed to call to him such auxiliary force as he might need." War actually existing and our territory having been invaded, General Taylor, pursuant to authority vested in him by my direction, has called on the governor of Texas for four regiments of State troops, two to be mounted and two to serve on foot, and on the governor of Louisiana for four regiments of infantry to be sent to him as soon as practicable.
In further vindication of our rights and defense of our territory, I invoke the prompt action of Congress to recognize the existence of the war, and to place at the disposition of the Executive the means of prosecuting the war with vigor, and thus hastening the restoration of peace. To this end I recommend that authority should be given to call into the public service a large body of volunteers to serve for not less than six or twelve months unless sooner discharged. A volunteer force is beyond question more efficient than any other description of citizen soldiers, and it is not to be doubted that a number far beyond that required would readily rush to the field upon the call of their country. I further recommend that a liberal provision be made for sustaining our entire military force and furnishing it with supplies and munitions of war.
The most energetic and prompt measures and the immediate appearance in arms of a large and overpowering force are recommended to Congress as the most certain and efficient means of bringing the existing collision with Mexico to a speedy and successful termination.
In making these recommendations I deem it proper to declare that it is my anxious desire not only to terminate hostilities speedily, but to bring all matters in dispute between this Government and Mexico to an early and amicable adjustment; and in this view I shall be prepared to renew negotiations whenever Mexico shall be ready to receive propositions or to make propositions of her own.
I transmit herewith a copy of the correspondence between our envoy to Mexico and the Mexican minister for foreign affairs, and so much of the correspondence between that envoy and the Secretary of State and between the Secretary of War and the general in command on the Del Norte as is necessary to a full understanding of the subject.
