But whatever may be thought of the value of this peninsula or of the gulf as a natural boundary between us and Mexico, instead of an imaginary line drawn from the Colorado to the Pacific, thus separating a kindred people, and exposing the governments of the two territories to continual collisions, the propriety of retaining Lower California is, in my opinion, now no longer an open question. When this country was first taken possession of by the forces of the United States, the people were promised the protection of our government against Mexico, and guarantied the rights secured by our Constitution; and in November, 1847, they were assured by the commander-in-chief of the Pacific squadron, (with the approbation of the Secretary of the Navy,) that this territory would be _permanently_ retained by the American government; and again, by the President of the United States, in his annual message of December, 1847, that it "should never be given up to Mexico." Acting under these assurances, all the most respectable people of the territory not only refused to take part with the Mexican forces which were sent to attempt the recapture of that country from the Americans, but many of them actually took up arms in our defence, and rendered most valuable services in ridding the peninsula of the guerrilla hordes sent over from Mexico for the purpose of effecting our expulsion. In this conflict, some who thus sided with us lost their lives, many their property, and all have exposed themselves to the vengeance of the Mexican government. But these losses and dangers they have willingly encountered, in the hope of obtaining the better government of the United States. They have regarded these promises as made in good faith, and have been guided in their conduct by the assurances thus held out to them by the agents of the American government; and now, for the United States to voluntarily surrender this country to the republic of Mexico, and leave these Californians exposed to the loss of life and confiscation of property for having sided with us, under the assurances thus held out to them, would not only be in itself a breach of national faith, but would make us appear in the eyes of the world guilty of the most deliberate and cruel deception.
