Arista, a bold and experienced officer, expecting Taylor to act on such a plan as Taylor seems actually to have formed, intended to charge both flanks of the advancing Americans with cavalry supported by infantry; but the American artillery surprised him almost as much as if Taylor had used shooting stars. Probably the right course for him would have been to attack anyhow, for his men were still eager to fight, a cannon could be discharged only about once a minute, and our batteries would not have done much more harm at 70 than at 700 yards. But apparently it seemed impracticable to wallow slowly for such a distance through the grass, the sharp edges of which would have cut the legs of his poorly dressed soldiers badly, under so withering a fire. Something had to be done, however, for the troops grew impatient. He therefore directed his right wing to prepare for a charge, and ordered Torrejón and his two small guns to attack the American right, rear and wagons. Reluctantly Torrejón obeyed. Passing to the left, his "red lancers"--probably a thousand strong and "portentous" with trumpets, banners and lance points--advanced through the scattered chaparral and across a slough, becoming somewhat broken on the way, and found themselves at another small morass. Evidently the nature of the ground on which he was likely to operate had not interested Torrejón.[8.14] Taylor, sitting unconcernedly with one leg over the pommel of his saddle, writing, was notified of this movement and simply replied, "Keep a bright lookout for them." But some one--probably Twiggs, who commanded the right wing--had the Fifth Infantry march rapidly more than a quarter of a mile to the right and rear, and throw itself into a square. Torrejón awkwardly approached this body in column instead of line with some of the worthless Presidials in the lead, fired ineffectively, was answered with a disconcerting though not very injurious volley, and recoiled some 300 yards. He then sent word to Arista that a morass rendered his movement impracticable; but on receiving instructions to persevere, he made a circuit, advanced upon the second front of the square, and once more exchanged a volley. Now, however, he found our Third Infantry moving to defend the wagons, and saw two of Ringgold's cannon hurrying to the scene at a gallop, while his own pieces had not come up. As rapidly as possible, therefore, and quite willingly, he retreated, but not without a salute from our two cannon, which he was unable to return. This unsuccessful manoeuvre exhausted Arista's ingenuity, and he only waited now for darkness, hoping to get away and find a better position.[8.14]
