It was under these circumstances and upon these considerations that it was deemed expedient not to obstruct his return to Mexico should he attempt to do so. Our object was the restoration of peace, and, with that view, no reason was perceived why we should take part with Paredes and aid him by means of our blockade in preventing the return of his rival to Mexico. On the contrary, it was believed that the intestine divisions which ordinary sagacity could not but anticipate as the fruit of Santa Anna's return to Mexico, and his contest with Paredes, might strongly tend to produce a disposition with both parties to restore and preserve peace with the United States. Paredes was a soldier by profession and a monarchist in principle. He had but recently before been successful in a military revolution, by which he had obtained power. He was the sworn enemy of the United States, with which he had involved his country in the existing war. Santa Anna had been expelled from power by the army, was known to be in open hostility to Paredes, and publicly pledged against foreign intervention and the restoration of monarchy in Mexico. In view of these facts and circumstances it was that when orders were issued to the commander of our naval forces in the Gulf, on the 13th day of May last, the same day on which the existence of the war was recognized by Congress, to place the coasts of Mexico under blockade, he was directed not to obstruct the passage of Santa Anna to Mexico should he attempt to return.
A revolution took place in Mexico in the early part of August following, by which the power of Paredes was overthrown, and he has since been banished from the country, and is now in exile. Shortly afterwards Santa Anna returned. It remains to be seen whether his return may not yet prove to be favorable to a pacific adjustment of the existing difficulties, it being manifestly his interest not to persevere in the prosecution of a war commenced by Paredes to accomplish a purpose so absurd as the reconquest of Texas to the Sabine. Had Paredes remained in power, it is morally certain that any pacific adjustment would have been hopeless.
Upon the commencement of hostilities by Mexico against the United States the indignant spirit of the nation was at once aroused. Congress promptly responded to the expectations of the country, and by the act of the 13th of May last recognized the fact that war existed, by the act of Mexico, between the United States and that Republic, and granted the means necessary for its vigorous prosecution. Being involved in a war thus commenced by Mexico, and for the justice of which on our part we may confidently appeal to the whole world, I resolved to prosecute it with the utmost vigor. Accordingly the ports of Mexico on the Gulf and on the Pacific have been placed under blockade and her territory invaded at several important points. The reports from the Departments of War and of the Navy will inform you more in detail of the measures adopted in the emergency in which our country was placed and of the gratifying results which have been accomplished.
The various columns of the Army have performed their duty under great disadvantages with the most distinguished skill and courage. The victories of Palo Alto and Resaca de la Palma and of Monterey, won against greatly superior numbers and against most decided advantages in other respects on the part of the enemy, were brilliant in their execution, and entitle our brave officers and soldiers to the grateful thanks of their country. The nation deplores the loss of the brave officers and men who have gallantly fallen while vindicating and defending their country's rights and honor.
It is a subject of pride and satisfaction that our volunteer citizen soldiers, who so promptly responded to their country's call, with an experience of the discipline of a camp of only a few weeks, have borne their part in the hard-fought battle of Monterey with a constancy and courage equal to that of veteran troops and worthy of the highest admiration. The privations of long marches through the enemy's country and through a wilderness have been borne without a murmur. By rapid movements the Province of New Mexico, with Santa Fe, its capital, has been captured without bloodshed. The Navy has cooperated with the Army and rendered important services; if not so brilliant, it is because the enemy had no force to meet them on their own element and because of the defenses which nature has interposed in the difficulties of the navigation on the Mexican coast. Our squadron in the Pacific, with the cooperation of a gallant officer of the Army and a small force hastily collected in that distant country, has acquired bloodless possession of the Californias, and the American flag has been raised at every important point in that Province.
I congratulate you on the success which has thus attended our military and naval operations. In less than seven months after Mexico commenced hostilities, at a time selected by herself, we have taken possession of many of her principal ports, driven back and pursued her invading army, and acquired military possession of the Mexican Provinces of New Mexico, New Leon, Coahuila, Tamaulipas, and the Californias, a territory larger in extent than that embraced in the original thirteen States of the Union, inhabited by a considerable population, and much of it more than 1,000 miles from the points at which we had to collect our forces and commence our movements. By the blockade the import and export trade of the enemy has been cut off. Well may the American people be proud of the energy and gallantry of our regular and volunteer officers and soldiers. The events of these few months afford a gratifying proof that our country can under any emergency confidently rely for the maintenance of her honor and the defense of her rights on an effective force, ready at all times voluntarily to relinquish the comforts of home for the perils and privations of the camp. And though such a force may be for the time expensive, it is in the end economical, as the ability to command it removes the necessity of employing a large standing army in time of peace, and proves that our people love their institutions and are ever ready to defend and protect them.
While the war was in a course of vigorous and successful prosecution, being still anxious to arrest its evils, and considering that after the brilliant victories of our arms on the 8th and 9th of May last the national honor could not be compromitted by it, another overture was made to Mexico, by my direction, on the 27th of July last to terminate hostilities by a peace just and honorable to both countries. On the 31st of August following the Mexican Government declined to accept this friendly overture, but referred it to the decision of a Mexican Congress to be assembled in the early part of the present month. I communicate to you herewith a copy of the letter of the Secretary of State proposing to reopen negotiations, of the answer of the Mexican Government, and of the reply thereto of the Secretary of State,
The war will continue to be prosecuted with vigor as the best means of securing peace. It is hoped that the decision of the Mexican Congress, to which our last overture has been referred, may result in a speedy and honorable peace. With our experience, however, of the unreasonable course of the Mexican authorities, it is the part of wisdom not to relax in the energy of our military operations until the result is made known. In this view it is deemed important to hold military possession of all the Provinces which have been taken until a definitive treaty of peace shall have been concluded and ratified by the two countries.
The war has not been waged with a view to conquest, but, having been commenced by Mexico, it has been carried into the enemy's country and will be vigorously prosecuted there with a view to obtain an honorable peace, and thereby secure ample indemnity for the expenses of the war, as well as to our much-injured citizens, who hold large pecuniary demands against Mexico.
By the laws of nations a conquered country is subject to be governed by the conqueror during his military possession and until there is either a treaty of peace or he shall voluntarily withdraw from it. The old civil government being necessarily superseded, it is the right and duty of the conqueror to secure his conquest and to provide for the maintenance of civil order and the rights of the inhabitants. This right has been exercised and this duty performed by our military and naval commanders by the establishment of temporary governments in some of the conquered Provinces of Mexico, assimilating them as far as practicable to the free institutions of our own country. In the Provinces of New Mexico and of the Californias little, if any, further resistance is apprehended from the inhabitants to the temporary governments which have thus, from the necessity of the case and according to the laws of war, been established. It may be proper to provide for the security of these important conquests by making an adequate appropriation for the purpose of erecting fortifications and defraying the expenses necessarily incident to the maintenance of our possession and authority over them.
