the Mexicans were driven from the summit; and in a moment big Sergeant Henry of the Seventh had the Stars and Stripes flying from the tower. Riley's men, pushing up through dense thickets under a hot fire, had now taken possession of the spur; and while some of them hurried on to join Harney, others shot down the gunners of the battery on the summit. In a twinkling Captain Magruder turned the pieces, and poured a storm of iron on the flying Mexicans. General Baneneli, commanding the reserve just below, tried hard to charge, but his men would not face the yelling Americans. The Grenadiers and the Eleventh Infantry, hurried by Santa Anna in that direction, were overwhelmed by the fugitives; Riley's advance plunged down the hill toward the Mexican camp; and an indescribable confusion ensued.[1]
Just at this time, after a fearful march of perhaps two miles, Shields with his foremost companies emerged from the chaparral on the Mexican left, and hastily prepared to charge. Three guns of the headquarters battery, one hundred and fifty or two hundred yards distant in their front, had been turned upon Riley, but the other two let fly at them. Shields fell and his men recoiled. It was no wonder. About three hundred raw volunteers, without regulars and without artillery, stood before cannon and an army! Some two thousand fresh horse under Canalizo, guarding that very ravine, faced them just at the left of the battery, and the cannon kept at work. But their mere emerging from the close chaparral at this point, in a strength which the enemy could not measure, was of itself a triumph.[2]
"The Yankees! They have come out to the road!" cried the Mexicans; "Every one for himself!" Some of Riley's men shot down or frightened away the gunners of the battery, and in another moment seized three of the pieces. At the same instant a section of Shields's brigade, which had now come up in more force, captured the other two, while a second section, followed by the Seventh Infantry, struck for the highway. Canalizo, afraid of being cut off, took flight, as many had already done; and all the rest of the Mexicans who could, either followed him or, like Santa Anna himself, rushed headlong down one or the other of two paths, narrow and steep, that descended into the canyon of the Río del Plan.
