There was not any general engagement of the armies after the capture of the City of Mexico. General Lane, always vigilant, kept his force in constant motion, pursuing, engaging, when possible, and dispersing the numerous predatory bands that infested his flanks and rear.

The first efforts to agree upon a treaty of peace failed. Active operations were resumed, and so weakened Mexico that she was left no alternative but to make "peace such as her powerful and successful enemy might dictate." By the Constitution of Mexico the office of President in case of a vacancy devolved upon the president of the Supreme Court provisionally; but there was no president of the Supreme Court in September, 1847, the last incumbent having died, and no successor having been elected when Santa Anna resigned. Congress, whose duty it was to elect this officer, could only be convened by proclamation of the President, but, as is seen, there was no President. In this unfortunate state of affairs, the most influential of the Moderado party, with the hope of preventing anarchy, then greatly threatened, if it had not already raised its head, and conclude terms of peace, prevailed upon Peña y Peña, an able and enlightened jurist, statesman, and patriot, and senior judge of the Supreme Court, to assume the provisional presidency. He was recognized by the State authorities, and pledges were given that they would uphold and defend it against all intriguers opposed to peace, through the non-existence of a government competent to make it. It was known that Peña was not averse to peace.

Mr. Nicholas P. Trist, the commissioner on the part of the United States, upon the formation of the new Government, made propositions for a conference of representatives. Owing to the fact that the Mexican Congress had to be called together to elect a President ad interim to serve until January 8, 1848, the overtures of Mr. Trist could not be entertained. By a combination between the Puro party and the adherents of Santa Anna and other factions, the Moderado party came very near being defeated, but the latter were successful and elected General Don Pedro Maria Anaya ad interim President; and Peña y Peña and General Mora y Villamil, both in favor of peace, were made respectively Minister of Foreign Relations and Minister of War.

Negotiations were now again formally undertaken. The Mexican Government was represented by Señores Conto, Atristain, and Cuevas. The commissioners of the respective countries met at Guadalupe Hidalgo, three miles from the City of Mexico. After many meetings, long conferences, and discussions, a treaty of peace, friendships, and limits between Mexico and the United States was concluded and signed February 2, 1848.

A synopsis of the treaty is given. Some of the articles are given in full, as the fifth, which secured to the United States the great State of California with its incalculable wealth in mineral and agriculture resources, and the territory of New Mexico, also rich in all that Nature can yield.

Treaty of Guadalupe Hidalgo, concluded February 2, 1848. Ratifications exchanged at Queretaro, May 30, 1848. Proclaimed July 4, 1848.

The United States was represented by Nicholas P. Trist, and the Republic of Mexico was represented by Don Louis Gonzaga Cuevas, Don Bernardo Conto, and Don Miguel Atristain.

"Article I. There shall be firm and universal peace between the United States of America and the Mexican Republic, and between respective countries, territories, cities, towns, and people, without exception of places or persons.

"Art. II provides that, immediately upon the signature to this treaty, commissioners shall be appointed by the commander in chief of the American forces and the Mexican Government for the provisional suspension of hostilities and the re-establishment of the political, administrative, and judicial branches so far as this shall be permitted by the circumstances of the case.

"Art. III. Immediately upon the ratification of this treaty by the United States orders shall be issued to the commanders of the land and naval forces, requiring the latter (provided this treaty has been ratified by Mexico and ratifications exchanged) to immediately desist from blockading any Mexican ports, and requiring the former (under the same conditions) to withdraw all troops of the United States then in the interior of the Mexican Republic to a distance from the seaport not exceeding thirty leagues—this to be done with the least possible delay; and to deliver up all customhouses at all ports occupied by the forces of the United States to persons authorized by the Mexican Government to receive it, with all bonds and evidences of debt for duties on importations and exportations. An exact account to be rendered of all duties on imports and exports, after the ratification of this treaty by Mexico, deducting only the cost of collection. The City of Mexico to be evacuated within one month after the orders there stipulated shall be received by the commander of said troops.
