Forward they went, scarcely a thousand, because very many comrades had fallen around them that day, but they had never been more eager for the charge. The smoke thinned out before them and they advanced swiftly with leveled rifles. They reached the southern edge of the plateau, and then they recoiled in horror. Santa Anna had not only saved a division by a trick, but he had used the same opportunity to draw in his columns and mass the heaviest force that had yet converged upon a single point. Ten thousand men appeared over the uneven ground and approached the single thousand. To face such numbers advancing with great guns was impossible. Again it seemed that the day, after a brilliant success, was lost. The Americans at once turned and rushed into a gorge for shelter and defense. The side of the gorge was so steep that Phil slipped and rolled to the bottom. But he quickly sprang up, unconscious of his bruises. Breakstone and Arenberg, with pale faces, were at his side. The gorge was not as much of a shelter and defense as it had seemed. It was instead a trap, the worst into which they had come that day. From the cliffs on both sides of the gorge the Mexicans sent down a continuous rain of bullets and shell. Santa Anna, exulting in his success, urged them on and, his seconds, Ampudia, Pacheco, Lombardini and the others, ran from point to point, encouraging their troops and crying that the battle was now won. The Americans fired upward at their enemies, but they were pressed together in great confusion. Men and officers went down so fast that it looked to Phil like hay falling before the scythe. Here fell the brave Colonel Clay, the son of the great Henry Clay, and with him McKee and Hardin and many other gallant sons of Kentucky and Illinois. A great horror seized Phil. Penned in that awful gorge, with that continuous shower of steel and lead from above, he felt as if he were choking. He and others rushed for the mouth of the gorge, but the wary Santa Anna had closed it with a great body of lancers, who were now advancing to assist in the complete destruction of the Americans. The defenders reeled back, and Santa Anna, thinking the time had come to deliver the final blow, sent the Mexican infantry in thousands down the sides of the gorge, where they attacked with the bayonet the few hundreds that yet fought. Phil was quite sure that no hope was left. Before, at every critical moment there had always been a slender chance of some kind or other, but now he could see absolutely none. A million red motes danced before him, and he struck almost blindly with his clubbed rifle at a Mexican who was trying to bayonet him.
