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; fhey 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.
