 Pedro de Alvarado pressed ahead and when the Spanish entered the town the defenders were completely unprepared, with the Pipil warriors indoors sheltering from the torrential rain.In the battle that ensued, the Spanish and their indigenous allies suffered minor losses but the Pipil were able to flee into the forest, sheltered from Spanish pursuit by the weather and the vegetation.Pedro de Alvarado ordered the town to be burnt and sent messengers to the Pipil lords demanding their surrender, otherwise he would lay waste to their lands.
