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.
