tifying intelligence was received of the signal victory of Buena
Vista, and of the fall of the city of Vera Cruz, and with it the strong
castle of San Juan de Ulloa, by which it was defended. Believing that
after these and other successes so honorable to our arms and so
disastrous to Mexico the period was propitious to afford her another
opportunity, if she thought proper to embrace it, to enter into
negotiations for peace, a commissioner was appointed to proceed to the
headquarters of our Army with full powers to enter upon negotiations and
to conclude a just and honorable treaty of peace. He was not directed to
make any new overtures of peace, but was the bearer of a dispatch from

instructed by the Secretary of War to suspend further active military
operations until further orders. These instructions were given with a

could be transmitted to Washington and receive the action of the
Government of the United States. The commissioner was also directed on
reaching the Army to deliver to the general in command the dispatch
which he bore from the Secretary of State to the minister of foreign
affairs of Mexico, and on receiving it the general was instructed by the
