continued to advance in spite of the obstacles which were calculated to discourage them.
The various detachments of the Mexican army were concentrated at San Fernando, and on the night of the 20th of February they encamped at Encenada. On the morning of the 21st mass was said in front of the different divisions, and at noon the whole column were again on the march; the brigade of light infantry under General Ampudia, accompanied by a body of lancers, leading the van; the divisions of infantry, under General Lombardini, in the centre; and the division of cavalry and infantry, under General Ortéga, bringing up the rear. General Miñon was ordered with his cavalry brigade to make a diversion in the rear of the American army, and occupy the hacienda of Buena Vista. The detachment under General Urrea at Tula had received instructions to advance from their position, and attack the American posts, and cut off their communications between Monterey and the Rio Grande.
It had been the intention of Santa Anna, on learning the position of General Taylor, to place his forces between the American army and Saltillo, and compel them to fight him at this disadvantage. The retrograde movement to Buena Vista defeated his project. His
eral Miñon's cavalry brigade was 1,200 strong; General Urrea had an indefinite number of men, varying from two to three thousand; General Vasquez remained at Matchuala with a brigade of infantry as a corps de reserve; and the main body under Santa Anna probably did not much exceed 17,000 men. The following general officers accompanied the army; Alvarez, general-in-chief of cavalry; Lombardini, commander-in-chief of the infantry; Requena, general — in — chief of artillery; Mora y Villamil, chief of the engineers; Micheltorena, chief of the general staff; and Generals R. Vasquez, Torrejon, Ampudia, Andradé, Juvera, Quintamar, Miñon, (detached,) Jaurequi, Conde, Pacheco, Gancia, Ortéga, Mejia, Flores, Guzman, Mora, and Romero.
