ammunition at Saltillo. Leaving O'Brien's two guns and one each of their own on the plateau, therefore, Bragg and Sherman were ordered to the north field.[1]
Here, soon after noon, a brigade of Mexican cavalry supported by infantry pushed resolutely forward to gain the Saltillo road near the long ravine. In order to find a better position and avoid the danger of being enveloped, the Mississippians retired some distance; but soon they halted, and with the Indiana men, who now rejoined them, formed an obtuse angle opening toward the mountain. Upon this obstacle the Mexican cavalry, drawn up in a close column, rushed down at an easy gallop in the most beautiful style, drawing small circles in the air with the glittering points of their lances. These men, too, were brilliantly uniformed, the horses were lavishly caparisoned, and all the plumes and flags and pennons were fluttering. Had they maintained their impetus, they could have carried all before them; but the attitude of the Americans, who made no attempt to form a square and merely stood still with shouldered arms, puzzled the Mexican leader. He wondered, probably, what there might be in the ravine close by them, and slackening speed he almost halted, about seventy yards away, at the very focus of their angle.[2]
But suddenly the muskets and rifles were levelled. Each man picked his target, and at the word "Fire!" — just as the Mexican bugler sounded the charge — two sheets of flame converged on that splendid brigade. The head of it fell to the ground, and the rest. were thrown into confusion. Then the Mississippi men leaped forward, yelling wildly, seized horses by the bits, threw them back on their haunches, and finished many a helpless rider with the 18-inch bowie-knife, while the Indianians fired and plied the bayonet, and Sherman, coming up with a howitzer, blasted out wide, red gaps. The onslaught was irresistible; the whole brigade with its infantry support recoiled; and the victors pressed on in pursuit.[3]
A deafening thunderstorm of rain and hail now burst upon the contending armies, but the battle in the north field hardly paused. While Sherman accompanied the right of the Mississippi and Indiana men, Bragg and a body of dragoons flanked their left;[4] the American artillery on the plateau, having little to do there, turned its attention upon the same dense masses;
