There is another consideration which induced the belief that the Mexican Government might even desire to place this Province under the protection of the Government of the United States. Numerous bands of fierce and warlike savages wander over it and upon its borders. Mexico has been and must continue to be too feeble to restrain them from committing depredations, robberies, and murders, not only upon the inhabitants of New Mexico itself, but upon those of the other northern States of Mexico. It would be a blessing to all these northern States to have their citizens protected against them by the power of the United States. At this moment many Mexicans, principally females and children, are in captivity among them. If New Mexico were held and governed by the United States, we could effectually prevent these tribes from committing such outrages, and compel them to release these captives and restore them to their families and friends. In proposing to acquire New Mexico and the Californias, it was known that but an inconsiderable portion of the Mexican people would be transferred with them, the country embraced within these Provinces being chiefly an uninhabited region. These were the leading considerations which induced me to authorize the terms of peace which were proposed to Mexico. They were rejected, and, negotiations being at an end, hostilities were renewed. An assault was made by our gallant Army upon the strongly fortified places near the gates of the City of Mexico and upon the city itself, and after several days of severe conflict the Mexican forces, vastly superior in number to our own, were driven from the city, and it was occupied by our troops. Immediately after information was received of the unfavorable result of the negotiations, believing that his continued presence with the Army could be productive of no good, I determined to recall our commissioner. A dispatch to this effect was transmitted to him on the 6th of October last. The Mexican Government will be informed of his recall, and that in the existing state of things I shall not deem it proper to make any further overtures of peace, but shall be at all times ready to receive and consider any proposals which may be made by Mexico.
