Alvarado described the Cuzcatlec soldiers as having shields decorated with colourful exotic feathers, a vest-like armour made of three inch cotton which arrows could not penetrate, and long spears. Both armies suffered many casualties, with a wounded Alvarado retreating and losing a lot of his men, especially among the Mexican Indian auxiliaries. Once his army had regrouped, Alvarado decided to head to the Cuzcatlan capital and again faced armed Cuzcatlec. Wounded, unable to fight and hiding in the cliffs, Alvarado sent his Spanish men on their horses to approach the Cuzcatlec to see if they would fear the horses, but they did not retreat, Alvarado recalls in his letters to Hernán Cortés.
