Farther toward Arista's left, however, our men pushed forward rather easily, though it seemed evident from the firing that Mexicans were in front. Gaining ground in this direction some Americans probably came upon a path which led round the western end of the pond, and gave access to the Mexican flank. Just before the battle began Ampudia learned of the path, and stationed at company of the Sappers and a company of the Fourth Infantry in this quarter; and later he sent another detachment from the Fourth with a gun. Besides these meagre forces probably no corps guarded the left except a few Tampico troops. These also fought well; but the splendid silk banner of the Veterans, the bravest corps in the army, was captured, and only at heavy cost could they fight their way back' Meantime the rest of Uraga's regiment came over from beyond the road, but it could not stop the Americans; and brave Captain Barbour, followed by a small party, soon approached the placeta. The effect was electrical. Nobody knew how many troops were following him. Canales took flight, The sense of defeat, already imparted by hurrying soldiers of the Second Light, spread across the road from the broken left, and at about half-past five o'clock Arista's right wing, the strength of the army, crumbled like a sand fort struck by a wave. Except perhaps one, all the corps dissolved; and in a moment, as it seemed, nothing was left but a mob of fugitives.[1]
During all this, Taylor, exposing himself as much as any one, had been fighting at the centre. The proper course to adopt there was to charge the Mexican guns on the road with infantry, but for some reason he sent May's dragoons against them. In a way the effort succeeded. Slashing as they galloped, the horsemen quickly ran over the batteries? more than a quarter of a mile beyond them, in fact; and then, coming back in a scattered condition, had a chance to slash again, for the batteries had been reoccupied. But the thickets on both sides were full of Mexican infantry. Against their muskets the dragoons were mere targets — broad ones, too; and before long the squadron, much the worse for its charge, recrossed the Resaca. Taylor was disgusted. Turning to Belknap and the Eighth Infantry he exclaimed, "Take those guns, and by keep them!" A part of the Fifth joined
