Oh, could we gain
Those heights beyond, where guns are calling,
Of deeds appalling,
One to the other not in vain,
Then might we conquer in the fray,
And victors be e'er close of day.
The stream lying between the two armies was called the Rio Tardo, from its slow-flowing current, and emerging from the interior mountains, pursued its way in many windings to the sea. Centeotl was built on the left bank, so that the loyalists were unable to occupy the town without crossing the river, and to do so they would have had to force a passage at the point of the sword. The battle took place about three miles from the city, on a large plain streaked here and there with low ranges of sandy hills, and intersected by the broad stream of the Rio Tardo.
On one of these ranges Don Hypolito had planted his artillery, and swept the river with his heavy guns. He also disposed his infantry along the banks, whence they kept up a regular fire of musketry on the loyalists. The bridge at Centeotl had been destroyed prior to the arrival of Benito, so that there was no way of crossing, save under fire from the foot soldiers, or in the teeth of the battery posted on the sandy ridges.
Behind this battery Xuarez held his cavalry in reserve, lest the loyalists should accomplish the passage of the river, and the combatants come to closer quarters. Between Centeotl and the position he had taken up, he placed a line of some thousand horse, with the object of preventing an attack by the besieged in his rear. In the disposition of his troops, he showed a wonderful skill in taking advantage of the capabilities of the ground, and General Benito saw plainly that it would be with considerable difficulty that he could effect a crossing of the Rio Tardo.
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.
