From this place his route lay through a dangerous and very narrow mountain defile, about six miles in length. The troops therefore marched forward with every military precaution, and began to ascend the acclivity. When they had arrived at the most elevated point of the pass, they found a fat old Indian female and a dog, which had been sacrificed to their gods; a certain sign of war. This indeed was soon verified; for they had not marched far before they came up with immense bodies of the enemy, who were lying in wait for them, so that Alvarado stood in great danger of being hemmed in on all sides. At this spot the pass was so narrow, and the ground so thickly strewed with stones, that the horse were scarcely able to render any assistance; but the crossbow-men, musketeers, and the rest of the foot, armed with bucklers and swords, closed the more bravely with the enemy, who retreated fighting, down the narrow pass to some deep hollows, where other bodies stood drawn up in order of battle. From this place the enemy, by a preconcerted plan, fell back, as Alvarado advanced, to another position, where they had posted above 6000 of their men. These were the warriors of Utatlan and their subjects, who had made sure they would easily be able to cut off Alvarado, with the whole of his men; but our troops fought with such determination and courage, that they put the enemy to flight, having only three of their men and two horses wounded. The enemy, however, rallied again, were joined by other large bodies, and renewed the attack with great intrepidity. The most desperate part of the action took place near a fountain, where a strong body of the enemy rushed forth from an ambush; so that the Spaniards were compelled to fight foot to foot with the Indians, who had in particular singled out the cavalry, and each horse was attacked by three of the enemy, while several others at the same time strove to pull them to the ground, by hanging to their tails. Here the Spaniards were placed in the utmost danger, for the enemy's numbers were overwhelming; but father Olmedo encouraged the men, reminding them that they were fighting with the intention of serving the Almighty, and to promote His holy religion; that the Lord would assist them, and that they must either conquer or die in this battle!
