Particularly sunny were the Mexican smiles at beautiful Cerralvo, where the advance arrived at noon, August 25; and there were still more substantial reasons for satisfaction. The town, a place of some 1800 people, was built of stone, and hence formed a strong military position. It had enough springs of excellent water to supply New York City, declared Taylor. Standing, all in white, on a ridge at the foot of a spur from the Sierra Madre, surrounded with groves, pastures and fields, it gave promise of abundance and kept the promise. Sheep, cattle and goats, watermelons, pecans, half a dozen delicious fruits, ample grazing, and large stores of corn were to be had, and plenty of oak, walnut, ebony, cypress and willow for the cooks' fires. By the morning of September 15, with the exception of the Texas contingent, which had marched by way of China and Cadereita, all the troops concentrated here.[11.10] [MEXICAN PLANS] Mexico, anticipating Taylor's advance, had now taken steps to meet it. In July Paredes had sent three brigades of regulars from the capital to operate against the revolutionists of Guadalajara, and on August 6 these were ordered to Monterey. Ampudia, who was to supersede Mejía, received instructions to make haste; and the commander of the third brigade, on leaving San Luis Potosí, went so far as to destroy all baggage that could hinder the march. News of the revolution, which overtook these forces tardily, delayed the advance, for of course many of the officers felt they must "pronounce"; and almost the whole of one brigade, abandoning their general, went back to Mexico. The number deserting was quite serious, for besides the usual reasons for leaving a distasteful service, the troops were alarmed by the prospect of real fighting, and the sombre monotony of the deserts that had to be crossed disheartened them.[11.11] But on August 29 the first brigade, about 1400 infantry with three 8-pounders, arrived at Monterey. The second came on September 6, and the third only a few days later. The garrison was now strong. Mejía had concentrated some 4000 regulars and auxiliaries, and according to the detailed official report there were in all, on September 10, 7303 officers and men. The arrival of the new forces greatly encouraged the soldiers of Palo Alto and the Resaca--who had felt little desire to meet the Americans again--and hence checked their deserting. As the cavalry had now been re-mounted, it seemed likely to be efficient; and when the Señorita Dosamantes, equipped as a captain, volunteered to fight the invader, and was exhibited on horseback to the entire army, its enthusiasm rose high.[11.11]
