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.
It would have been madness for Don Hypolito to cross the stream, and with his few attack the many of the loyalists. The river was his great safeguard, and so long as that interposed its waters between him and the enemy, he felt comparatively safe, trusting to hold his position until the arrival of the Indians from the north, whom he counted upon taking the enemy in the rear. He saw plainly that his men were growing weary of remaining solely on the defensive, and submitting to be cut to pieces by the fire of Benito's artillery; but, until he saw a prospect of being reinforced by the Indians, he was powerless to do anything but stubbornly prevent the loyalists from fording the stream.
General Benito saw that the rebel leader was unaware of the disaffection of the allies, and relied on their arriving shortly to turn the tide of war in his favour. With a view, therefore, to dishearten him, he ordered an Indian scout, attached to his staff, to ford the river if possible, below the battery point, present himself to Xuarez as a deserter from the loyalists, and inform him that the Indians had retreated. The scout at once obeyed, and attempted to swim the river, but just as he was close on the opposite bank, a rifle-shot struck him, and it was with the greatest difficulty that he regained the shore. Several rebel soldiers ran up to finish him with their bayonets, but he implored them to take him to Xuarez, as he was in possession of certain facts relating to the allies.
On being brought into the presence of the rebel leader, he had just time to tell Don Hypolito of the uselessness of counting on the Indians, and shortly afterwards expired. Xuarez thought at first it was a device of the loyalists to gain time, but as hour after hour went on, and no Indians appeared, he began to believe that he was indeed foolish to depend upon help from that quarter. The full terror of his position came on him at once. He saw that, deserted by the Indians, cut off from Acauhtzin, the whole success of the rebellion against the Junta depended upon his cutting the army of Benito to pieces. Janjalla was behind him, and he several times thought of falling back on that town, but the knowledge that it was being bombarded by the loyalist fleet withheld him from committing such a folly. Centeotl was held in the interests of the Junta. There was no chance of safety there, so he saw that he must remain in his present position, and either tire out Benito by holding his position stubbornly, or dash across the river with the main portion of his troops, and try the fortune of war in a hand-to-hand fight.
With characteristic boldness he decided on the latter of these alternatives, and sent forward a thousand cavalry to cross the river, and carry the war into the enemy's camp. Midway between the two batteries, which still kept up their fire, he brought fifteen field-guns to bear on the masses of infantry on the other bank, armed only with their rifles, hoping to cut them to pieces, and thus afford his cavalry a safe landing. Benito ordered five gatling guns to silence the field battery, and prevent, if possible, the landing of the insurgent cavalry. Unfortunately, his orders could not be accomplished smartly enough, and before the gatlings could be brought into position, the field-guns of Xuarez had opened a heavy fire on the infantry, under cover of which five hundred horse-men crossed the stream. The landing once effected, others followed, and the cavalry rode down the infantry like sheep, while right and left the balls from the field-guns of Xuarez cut passages in the crowded masses. For the moment the advantage was decidedly with Don Hypolito.
At once a thousand cavalry, held in reserve behind the battery, were hurled forward on the horsemen of the rebels. Five hundred had now crossed the stream, and there held the loyalists at bay while their comrades formed. The rebel regiment pierced like a wedge into the mass of infantry, and met the cavalry of Benito some distance from the bank of the river. What with these horsemen, and the incessant firing of the field-guns, the infantry of Benito were thoroughly demoralised, and flying in all directions. The cavalry of Xuarez, with admirable discipline, formed into lines as soon as they crossed the river, and steadily drove the horsemen of the loyalists backward.
Xuarez at once took advantage of this gain, and, behind his cavalry, sent regiment after regiment of infantry with orders to carry the battery of Benito by storm. In vain the foot-soldiers of the loyalists were hurled against the advancing mass of rebel horse and foot now marching steadily for the battery. They did not give way one inch. Xuarez hoped to capture the battery, turn the guns against the loyalists, and then bringing the rest of his troops across the stream.
This unexpected manœuvre had taken Benito by surprise, and there was but little doubt that if the battery were captured a panic would ensue amongst his own men, and thus give Xuarez a decided advantage. The columns of rebels pouring across the stream pierced the host of loyalists like a wedge and bore steadily down on the battery which was still under the heavy fire of the insurgent artillery posted on the sandhills.
Things looked black at that moment for the loyalist army, but at this critical juncture the troops of Benito succeeded in forcing the passage of the stream further up near the city. What the Opposidores had done in the centre of the line they did at its end, and, under cover of a heavy fire from their gatlings, managed to cross the stream and capture the field-guns of the enemy. These were at once utilised and turned on the rebels, and in a few minutes were pouring a deadly fire into the masses of cavalry and infantry sent to hold the bridge passage by Xuarez. An officer galloped post-haste to Benito, informing him of the crossing of the stream, and the General recognising that he might cut off the forces of Xuarez on the left bank, sent to the bridge all the soldiers he could spare, amounting to some fifteen hundred.
