under Mora y Villamil, with three pieces of artillery, moving along the road towards the centre. A battery of eight-pounders, consisting of eight pieces, was planted on the crest of a hill near the road where the different columns were formed for the attack, and General Ortéga remained in command of a strong reserve.
The column advancing against the centre was checked in a few moments by a rapid fire from Washington's battery, which opened wide gaps in the opposing ranks. The enemy broke and retired. The lancers were interposed to prevent the retreat, and drive the infantry forward. But they could better meet the spear-points of their countrymen, than the scathing torrent that poured down that roadway. Retreating in confusion they joined the column moving towards the American left. In this quarter the attack was more successful. The heavy Mexican battery was pushed to the foot of the heights which the light troops had ascended, and their cavalry and infantry, advancing up the bed of a ravine in front of the American line, soon gained a position on the plateau. The battle now commenced in earnest. The 2nd Indiana sustained themselves for a short time without faltering, and Lieutenant O'Brien opened a vigorous fire which mowed down the enemy in scores. His guns were advanced. Once more the Mexican line began to waver, and the infantry were again driven forward by the lancers. A single bold and vigorous onset would have secured the victory. General Lane urged his men to stand firm — to push upon the enemy. But the fire was too terrible. The Indiana regiment reeled to and fro like a drunken man. They staggered back and retired from the field in confusion, at the moment when General Taylor arrived from Saltillo.
