“Forward—double time—march!”
The Cadwalader men had joined again. They had entered the bridgehead closely behind the Second Brigade. In column of platoons all doubled up the road, which was strewn with bodies and plunder. The rout was on before and extended as far as eye might see; but a desperate battle was raging only a mile distant.
The column was in time; in fact, may not have been needed. The flight from the bridgehead and the church proved too much for the Santa Anna soldiers. General Pierce’s Ninth, Twelfth and Fifteenth Regulars, and General Shields’ New Yorkers and South Carolinans, two thousand men, were having a give-and-take with General Santa Anna’s reserve of four thousand infantry and three thousand lancers. But before the General Worth and General Pillow column arrived, the Mohawks were seen to charge—the Mexicans did not stand—their line wavered, the Pierce Regulars struck it on right and left—the center burst apart, all the line broke into fragments, fleeing for the road; and when the First Brigade, led by General Worth and Colonel Garland, panted in the Santa Anna troops had mingled with the vast throng of refugees from Churubusco.
The Pierce Regulars and the Shields’ Volunteers met the van of the First Division.
“On, men! To the city!”
No time was granted to the Mexicans to re-form; their infantry, artillery and camp followers jammed the road and flowed out upon either side. Lancers protected the rear, and threatened the pursuit. Matters looked good. The First Division, both of General Pillow’s Third Division brigades (General Cadwalader’s and General Pierce’s), and the Shields Mohawks were united, a victorious little army, and cared nothing about the lancers; the road to the capital was open. Hooray!
But—
“Column, halt!”
The drums beat, the bugles rang.
The column was two miles and a half from Churubusco, and only a mile and a half from the city gate. The Mexican rout had attempted no stand; the foremost of its dense mob were already jostling in. General Worth evidently was uncertain what to do—whether to follow right on or wait for orders. He and General Pillow and General Shields consulted together, sitting their horses. Huzzah! Huzzah for the dragoons! Here they came at a gallop, from behind, under Colonel Harney, and tore in to General Worth.
