Waddy Thompson, United States Minister to Mexico, to Abel P. Upshur, Secretary of State of the United States


Mexico, October 14, 1843.


Sir: ... I have not yet received the projet of a Convention from Mr Bocanegra, although it is now Saturday of the week when it was promised. I shall keep this despatch open, till the last moment so as to send it to you by the packet, which sails on the 19th, and the mail for which leaves here to night. I have some hope of succeeding in the matter. This hope is solely founded on the prospect of a collision between this country and England, an event regarded by all as something more than probable. In that event I know that they will desire our interposition. In a long and very full conversation with Santa Anna, just before he left this city, when he told me that Mexico desired war with England, arid that such a war could not injure Mexico: I said to him “how will it be, if they seize California?” He replied; “If there is danger of that we will cede it to you.” You will remember that it was the fear of the seizure of Louisiana by England that induced Bonaparte to cede it to us. The acquisition of California will be of little less importance to us. You will see that in my first despatch, I called the attention of the Government to this subject, and I beg that full instructions may be sent me on the subject. There is no prospect whatever of such a cession, but in the event of a war between Mexico and England. Then nothing would be easier...
