In 1837 Bustamente was recalled. On the succession of Pedraza to the presidency, he had been banished, and went away to pursue his medical studies in France; for he, like Farías, had received a diploma as doctor of medicine, and had been the family physician of the viceroy Calleja. He returned to Mexico on the outbreak of the Texan revolution, was made President, and filled the office with dignity and respectability, whenever he was allowed to, by his untiring enemy, or rival, Santa Anna, who, however, was sometimes on his side. In 1840 there was trouble again, with Santa Anna at the head of the government forces. Against him was arrayed General Mejia, a Mexican known for his valor, which amounted to rashness. He was a rival and personal enemy to Santa Anna, and the struggle between them was a duel _à la mort_. Fate was against Mejia and he perished. Taken prisoner on the field of battle at the hacienda La Blanca, he was shot. It is said that, being informed of the sentence of death passed upon him, he asked when he was to be shot. "In three hours," answered the official. "If Santa Anna had fallen into my power, I should have given him only three minutes," was his reply. There have been other generals of the same name and family who have shown equal bravery in death. In September, 1841, occurred another brief revolution, so fully described by Madame Calderon, that it may serve as a specimen. She says: "This revolution is like a game of chess, in which kings, castles, knights, and bishops are making different moves, while the pawns are looking on and taking no part whatever. "To understand the state of the board, it is necessary to explain the position of the four principal pieces,--Santa Anna, Bustamente, Paredes, and Valencia. The first move was made by Paredes, who published his 'Plan,' and _pronounced_ on the 8th of August, at Guadalajara. Shortly after a newspaper of Vera Cruz, entirely devoted to Santa Anna, _pronounced_ in favor of the 'Plan' of Paredes, and Santa Anna, with a few miserable troops, and a handful of cavalry, arrived at Perote. Here he remains for the present, kept in check by the government forces. Meanwhile Paredes, with about six hundred men, left Guadalajara and marched upon Guanajuato, and there a blow was given to the government party through the defection of General Cortazar, who thought fit thus to show his grateful sense of having just received the rank of general of brigade, with the insignia of this new grade, which the President put on with his own hands. Another check to the President. Once begun, defection spread rapidly, and Paredes and Cortazar, having advanced upon Querétaro, found that the General there had _pronounced_ just at the moment he was expected in Mexico to assist the government.
