These Provinces are now in our undisputed occupation, and have been so for many months, all resistance on the part of Mexico having ceased within their limits. I am satisfied that they should never be surrendered to Mexico. Should Congress concur with me in this opinion, and that they should be retained by the United States as indemnity, I can perceive no good reason why the civil jurisdiction and laws of the United States should not at once be extended over them. To wait for a treaty of peace such as we are willing to make, by which our relations toward them would not be changed, can not be good policy; whilst our own interest and that of the people inhabiting them require that a stable, responsible, and free government under our authority should as soon as possible be established over them. Should Congress, therefore, determine to hold these Provinces permanently, and that they shall hereafter be considered as constituent parts of our country, the early establishment of Territorial governments over them will be important for the more perfect protection of persons and property; and I recommend that such Territorial governments be established. It will promote peace and tranquillity among the inhabitants, by allaying all apprehension that they may still entertain of being again subjected to the jurisdiction of Mexico. I invite the early and favorable consideration of Congress to this important subject.
Besides New Mexico and the Californias, there are other Mexican Provinces which have been reduced to our possession by conquest. These other Mexican Provinces are now governed by our military and naval commanders under the general authority which is conferred upon a conqueror by the laws of war. They should continue to be held, as a means of coercing Mexico to accede to just terms of peace. Civil as well as military officers are required to conduct such a government. Adequate compensation, to be drawn from contributions levied on the enemy, should be fixed by law for such officers as may be thus employed. What further provision may become necessary and what final disposition it may be proper to make of them must depend on the future progress of the war and the course which Mexico may think proper hereafter to pursue.
With the views I entertain I can not favor the policy which has been suggested, either to withdraw our Army altogether or to retire to a designated line and simply hold and defend it. To withdraw our Army altogether from the conquests they have made by deeds of unparalleled bravery, and at the expense of so much blood and treasure, in a just war on our part, and one which, by the act of the enemy, we could not honorably have avoided, would be to degrade the nation in its own estimation and in that of the world. To retire to a line and simply hold and defend it would not terminate the war. On the contrary, it would encourage Mexico to persevere and tend to protract it indefinitely. It is not to be expected that Mexico, after refusing to establish such a line as a permanent boundary when our victorious Army are in possession of her capital and in the heart of her country, would permit us to hold it without resistance. That she would continue the war, and in the most harassing and annoying forms, there can be no doubt. A border warfare of the most savage character, extending over a long line, would be unceasingly waged. It would require a large army to be kept constantly in the field, stationed at posts and garrisons along such a line, to protect and defend it. The enemy, relieved from the pressure of our arms on his coasts and in the populous parts of the interior, would direct his attention to this line, and, selecting an isolated post for attack, would concentrate his forces upon it. This would be a condition of affairs which the Mexicans, pursuing their favorite system of guerrilla warfare, would probably prefer to any other. Were we to assume a defensive attitude on such a line, all the advantages of such a state of war would be on the side of the enemy. We could levy no contributions upon him, or in any other way make him feel the pressure of the war, but must remain inactive and await his approach, being in constant uncertainty at what point on the line or at what time he might make an assault. He may assemble and organize an overwhelming force in the interior on his own side of the line, and, concealing his purpose, make a sudden assault upon some one of our posts so distant from any other as to prevent the possibility of timely succor or reenforcements, and in this way our gallant Army would be exposed to the danger of being cut off in detail; or if by their unequaled bravery and prowess everywhere exhibited during this war they should repulse the enemy, their numbers stationed at any one post may be too small to pursue him. If the enemy be repulsed in one attack, he would have nothing to do but to retreat to his own side of the line, and, being in no fear of a pursuing army, may reenforce himself at leisure for another attack on the same or some other post. He may, too, cross the line between our posts, make rapid incursions into the country which we hold, murder the inhabitants, commit depredations on them, and then retreat to the interior before a sufficient force can be concentrated to pursue him. Such would probably be the harassing character of a mere defensive war on our part. If our forces when attacked, or threatened with attack, be permitted to cross the line, drive back the enemy, and conquer him, this would be again to invade the enemy’s country after having lost all the advantages of the conquests we have already made by having voluntarily abandoned them. To hold such a line successfully and in security it is far from being certain that it would not require as large an army as would be necessary to hold all the conquests we have already made and to continue the prosecution of the war in the heart of the enemy’s country. It is also far from being certain that the expenses of the war would be diminished by such a policy. I am persuaded that the best means of vindicating the national honor and interest and of bringing the war to an honorable close will be to prosecute it with increased energy and power in the vital parts of the enemy’s country.
In my annual message to Congress of December last I declared that--
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.
Such, in my judgment, continues to be our true policy; indeed, the only policy which will probably secure a permanent peace.
It has never been contemplated by me, as an object of the war, to make a permanent conquest of the Republic of Mexico or to annihilate her separate existence as an independent nation. On the contrary, it has ever been my desire that she should maintain her nationality, and under a good government adapted to her condition be a free, independent, and prosperous Republic. The United States were the first among the nations to recognize her independence, and have always desired to be on terms of amity and good neighborhood with her. This she would not suffer. By her own conduct we have been compelled to engage in the present war. In its prosecution we seek not her overthrow as a nation, but in vindicating our national honor we seek to obtain redress for the wrongs she has done us and indemnity for our just demands against her. We demand an honorable peace, and that peace must bring with it indemnity for the past and security for the future. Hitherto Mexico has refused all accommodation by which such a peace could be obtained.
Whilst our armies have advanced from victory to victory from the commencement of the war, it has always been with the olive branch of peace in their hands, and it has been in the power of Mexico at every step to arrest hostilities by accepting it.
One great obstacle to the attainment of peace has undoubtedly arisen from the fact that Mexico has been so long held in subjection by one faction or military usurper after another, and such has been the condition of insecurity in which their successive governments have been placed that each has been deterred from making peace lest for this very cause a rival faction might expel it from power. Such was the fate of President Herrera’s administration in 1845 for being disposed even to listen to the overtures of the United States to prevent the war, as is fully confirmed by an official correspondence which took place in the month of August last between him and his Government, a copy of which is herewith communicated. “For this cause alone the revolution which displaced him from power was set on foot” by General Paredes. Such may be the condition of insecurity of the present Government.
There can be no doubt that the peaceable and well-disposed inhabitants of Mexico are convinced that it is the true interest of their country to conclude an honorable peace with the United States, but the apprehension of becoming the victims of some military faction or usurper may have prevented them from manifesting their feelings by any public act. The removal of any such apprehension would probably cause them to speak their sentiments freely and to adopt the measures necessary for the restoration of peace. With a people distracted and divided by contending factions and a Government subject to constant changes by successive revolutions, the continued successes of our arms may fail to secure a satisfactory peace. In such event it may become proper for our commanding generals in the field to give encouragement and assurances of protection to the friends of peace in Mexico in the establishment and maintenance of a free republican government of their own choice, able and willing to conclude a peace which would be just to them and secure to us the indemnity we demand. This may become the only mode of obtaining such a peace. Should such be the result, the war which Mexico has forced upon us would thus be converted into an enduring blessing to herself. After finding her torn and distracted by factions, and ruled by military usurpers, we should then leave her with a republican government in the enjoyment of real independence and domestic peace and prosperity, performing all her relative duties in the great family of nations and promoting her own happiness by wise laws and their faithful execution.
