If, after affording this encouragement and protection, and after all the persevering and sincere efforts we have made from the moment Mexico commenced the war, and prior to that time, to adjust our differences with her, we shall ultimately fail, then we shall have exhausted all honorable means in pursuit of peace, and must continue to occupy her country with our troops, taking the full measure of indemnity into our own hands, and must enforce the terms which our honor demands.

To act otherwise in the existing state of things in Mexico, and to withdraw our Army without a peace, would not only leave all the wrongs of which we complain unredressed, but would be the signal for new and fierce civil dissensions and new revolutions--all alike hostile to peaceful relations with the United States. Besides, there is danger, if our troops were withdrawn before a peace was conducted, that the Mexican people, wearied with successive revolutions and deprived of protection for their persons and property, might at length be inclined to yield to foreign influences and to cast themselves into the arms of some European monarch for protection from the anarchy and suffering which would ensue. This, for our own safety and in pursuance of our established policy, we should be compelled to resist. We could never consent that Mexico should be thus converted into a monarchy governed by a foreign prince.

Mexico is our near neighbor, and her boundaries are coterminous with our own through the whole extent across the North American continent, from ocean to ocean. Both politically and commercially we have the deepest interest in her regeneration and prosperity. Indeed, it is impossible that, with any just regard to our own safety, we can ever become indifferent to her fate.

It may be that the Mexican Government and people have misconstrued or misunderstood our forbearance and our objects in desiring to conclude an amicable adjustment of the existing differences between the two countries. They may have supposed that we would submit to terms degrading to the nation, or they may have drawn false inferences from the supposed division of opinion in the United States on the subject of the war, and may have calculated to gain much by protracting it, and, indeed, that we might ultimately abandon it altogether without insisting on any indemnity, territorial or otherwise. Whatever may be the false impressions under which they have acted, the adoption and prosecution of the energetic policy proposed must soon undeceive them.

In the future prosecution of the war the enemy must be made to feel its pressure more than they have heretofore done. At its commencement it was deemed proper to conduct it in a spirit of forbearance and liberality. With this end in view, early measures were adopted to conciliate, as far as a state of war would permit, the mass of the Mexican population; to convince them that the war was waged, not against the peaceful inhabitants of Mexico, but against their faithless Government, which had commenced hostilities; to remove from their minds the false impressions which their designing and interested rulers had artfully attempted to make, that the war on our part was one of conquest, that it was a war against their religion and their churches, which were to be desecrated and overthrown, and that their rights of person and private property would be violated. To remove these false impressions, our commanders in the field were directed scrupulously to respect their religion, their churches, and their church property, which were in no manner to be violated; they were directed also to respect the rights of persons and property of all who should not take up arms against us.

Assurances to this effect were given to the Mexican people by Major General Taylor in a proclamation issued in pursuance of instructions from the Secretary of War in the month of June, 1846, and again by Major-General Scott, who acted upon his own convictions of the propriety of issuing it, in a proclamation of the 11th of May, 1847. In this spirit of liberality and conciliation, and with a view to prevent the body of the Mexican population from taking up arms against us, was the war conducted on our part. Provisions and other supplies furnished to our Army by Mexican citizens were paid for at fair and liberal prices, agreed upon by the parties. After the lapse of a few months it became apparent that these assurances and this mild treatment had failed to produce the desired effect upon the Mexican population. While the war had been conducted on our part according to the most humane and liberal principles observed by civilized nations, it was waged in a far different spirit on the part of Mexico. Not appreciating our forbearance, the Mexican people generally became hostile to the United States, and availed themselves of every opportunity to commit the most savage excesses upon our troops. Large numbers of the population took up arms, and, engaging in guerrilla warfare, robbed and murdered in the most cruel manner individual soldiers or small parties whom accident or other causes had separated from the main body of our Army; bands of guerrilleros and robbers infested the roads, harassed our trains, and whenever it was in their power cut off our supplies.

The Mexicans having thus shown themselves to be wholly incapable of appreciating our forbearance and liberality, it was deemed proper to change the manner of conducting the war, by making them feel its pressure according to the usages observed under similar circumstances by all other civilized nations.

Accordingly, as early as the 22d of September, 1846, instructions were given by the Secretary of War to Major-General Taylor to “draw supplies” for our Army “from the enemy without paying for them, and to require contributions for its support, if in that way he was satisfied he could get abundant supplies for his forces.” In directing the execution of these instructions much was necessarily left to the discretion of the commanding officer, who was best acquainted with the circumstances by which he was surrounded, the wants of the Army, and the practicability of enforcing the measure. General Taylor, on the 26th of October, 1846, replied from Monterey that “it would have been impossible hitherto, and is so now, to sustain the Army to any extent by forced contributions of money or supplies.” For the reasons assigned by him, he did not adopt the policy of his instructions, but declared his readiness to do so “should the Army in its future operations reach a portion of the country which may be made to supply the troops with advantage.” He continued to pay for the articles of supply which were drawn from the enemy’s country.

Similar instructions were issued to Major-General Scott on the 3d of April, 1847, who replied from Jalapa on the 20th of May, 1847, that if it be expected “that the Army is to support itself by forced contributions levied upon the country we may ruin and exasperate the inhabitants and starve ourselves.” The same discretion was given to him that had been to General Taylor in this respect. General Scott, for the reasons assigned by him, also continued to pay for the articles of supply for the Army which were drawn from the enemy.

After the Army had reached the heart of the most wealthy portion of Mexico it was supposed that the obstacles which had before that time prevented it would not be such as to render impracticable the levy of forced contributions for its support, and on the 1st of September and again on the 6th of October, 1847, the order was repeated in dispatches addressed by the Secretary of War to General Scott, and his attention was again called to the importance of making the enemy bear the burdens of the war by requiring them to furnish the means of supporting our Army, and he was directed to adopt this policy unless by doing so there was danger of depriving the Army of the necessary supplies. Copies of these dispatches were forwarded to General Taylor for his government.
