while some 1500 or 2000 cavalry, probably consisting of the horse that had followed him to San Angel reinforced by that which had escaped from Contreras, menaced — though afraid to attack — Shields's left.[1]
Precisely what occurred now cannot be stated, for apparently most of the reporting officers were more anxious to conceal than to disclose facts; but it seems clear that Shields handled the men clumsily, that his own regiments fell into disorder when charging and shrank from the devouring Mexican fire, and that Pierce's brigade, composed of excellent material but officered to a large extent with political favorites, actually skulked. The Mexicans, on the other hand, finding two ditches along the highway to protect them from the dreaded bayonet and an embankment to screen them somewhat from bullets, fought stiffly. Shields was therefore unable, with his six hundred good men and two small howitzers, to make any impression, and after a time his troops huddled wherever they could in the shelter of some buildings.[2]
But finally, between three and four o'clock, the spell broke. Worth's men, though astonished and for a time dismayed, had no thought of giving up. "Victory or death" was not a phrase to them, but a conviction. Though dikes, ditches, bad ground, corn higher than their heads, and the Mexican artillery fire broke up their organization, personal courage and personal leadership survived. In smaller or larger groups they fought on. Santa Anna, by taking the Fourth Ligero from Pérez to defend the rear, deducted half the strength of his left wing, and no doubt Shields's operations, very suggestive of the American methods used in previous battles, tended to make the troops at the bridgehead nervous. Gradually a part of the unlucky Sixth and men of C. F. Smith's and Garland's commands, working toward the extreme American right, outreached the enemy, crossed the river, turned the Mexican line, and moved on toward the highway. This created great alarm. The fate of Valencia was recalled. Many of the officers wilted. Ammunition seems partially to have failed; and at length, under a still galling fire, some of the Eighth Infantry, followed by more of the Fifth, waded the ditch of the bridgehead — twenty feet bread it was — climbed over the parapet or pushed through the embrasures, and settled the question hand to hand.[3]
