According to Alva Ixtlilxóchitl, the issue began when Moctezuma sent an embassy to Nezahualpilli reprimanding him for not sacrificing any Tlaxcalan prisoners since the last 4 years, during the war with Tlaxcala (see below), threatening him saying that he was angering the gods. Nezahualpilli replied to this embassy stating that the reason he had not sacrificed them was that he simply did not want to wage war because he and his population wanted to live peacefully for the time being, as the ceremonies that would be held in the following year, 1 reed, would make war inevitable, and that soon his wishes would be granted. Eventually, Nezahualpilli launched a campaign against Tlaxcala, though he did not go himself, instead sending two of his sons, Acatlemacoctzin and Tecuanehuatzin, as commanders. Moctezuma then decided to betray Nezahualpilli by sending a secret embassy to Tlaxcala telling them about the incoming army. The Tlaxcalans then began to take action against the Texcoca while they were unaware of this betrayal. The Texcoco armies were ambushed in the middle of the night. Almost none of the Texcoca survived the fight. Upon receiving the news of Moctezuma's betrayal, understanding that nothing could be done about it and fearing for the future of his people, Nezahualpilli committed suicide in his palace.
