the two cannon lost so nobly at Buena Vista; but the rest of the victorious troops pursued the enemy to San Angel; and the Mexicans fleeing by the turnpike toward Ansaldo, cannonaded from their own camp and running the gantlet of Smith, Ransom and even Shields, who had moved down toward the road, fared badly. Others, including Torrejón and a large part of the cavalry, managed by taking rough paths to reach San Geronimo and the hills. Valencia also escaped; but Salas, who tried to check the flight, was captured. Seven hundred Mexicans fell, it was estimated; over eight hundred were made prisoners; the captured cannon, including the best that Santa Anna had, and the captured ammunition proved invaluable; and the cost, as reported by Scott, was not over sixty Americans killed and wounded.[1]
Nor were such the only consequences of this lightning-stroke. Santa Anna, having at length decided to rescue Valencia and raised his forces to at least 7000 by drawing Rangel's reserve brigade from the city, had set out at daybreak for his position of the night before; but when in sight of Valencia's camp he learned from flying soldiers that all was over, and that his outer line of defences had failed. Angrily striking at fugitives with his whip he turned back, and waited near San Angel for a while, unable to decide anything. Then he sent Rangel to guard the southwest section of Mexico, despatched orders to evacuate San Antonio and Mexicaltzingo, and marched with the rest of his forces to Churubusco. Here priceless time was spent in raving against Valencia — -whom he ordered shot at sight — in a passion that almost crazed him. His dominant idea now, so far as he could think at all, was to make the capital a second Troy; and, probably with that in view, he set Pérez's brigade in motion toward the city.[2]
After a time, however, reason gained the better of desperation, and seeing the necessity of protecting the retreat of the San Antonio garrison, he ordered General Rincón, who was ably seconded by Anaya, to hold the Churubusco convent as long as possible, garrisoned the bridgehead with one of Pérez's regiments, extended two others far down behind the embankment of the river eastwardly, used a part of the remaining two as a line from the bridgehead to the convent, and stationed the rest on the highway behind.[3]
