On his side there were no ranges of hills upon which he could post his artillery, or by which he could protect his men. Nothing but a desolate plain covered with brushwood incapable of offering the least shelter against the devastating fire of the insurgents. His only way of crossing the river was to silence the battery on the sandhills. With this object, he brought up his field-guns, and opened a heavy cannonade on the heights beyond. The rebels replied, and for over two hours this cross fire went on without intermission on either side. Benito trusted by this gunnery to deceive the insurgents as to his real purpose, which was to attempt a crossing with five hundred horse three miles further up the stream, near the ruins of the bridge. By doing so he could take Xuarez in the rear, and while the rebels were employed in facing this new danger from an unexpected quarter, hoped to cross the river with his full force. Don Hypolito evidently suspected this stratagem, for he kept a sharp eye on the disposition of the loyalist army in the direction of Centeotl. When he saw a body of horse move citywards to effect a crossing, he at once sent a troop of cavalry to dispute the passage. Benito seeing this, despatched a battery of six gatlings to support his troops, trusting that under the cover of these guns playing on the enemy they could force the stream. At once Xuarez brought up his field-artillery, and in a short space of time the cannonading lower down the river was being repeated further up at the ruins of the bridge. The right wing of the loyalist army, consisting entirely of infantry, was thrown forward in the direction of Centeotl, and kept up a fusillade, under cover of which the cavalry in scattered groups tried to cross. The insurgents, however, could not be dislodged from the opposite bank, and it was impossible to accomplish the passage under their persistent musketry. For close on three miles along the banks of the river this line of sharp-shooters extended, and at each end of the line artillery thundered incessantly. Men on either side were dropping every moment, and it seemed as though each army would annihilate the other without either crossing the stream. For four hours the battle had been raging without the combatants coming to close quarters, and Xuarez's soldiers remaining ever on the defensive, began to grow impatient. On the other hand, the Royalists trying to carry the passage of the stream by dash after dash, were warming up to their work.
