This occurred while Sandoval was preparing to leave for Tlascala to convey the brigantines, and no further troops could therefore be detached without great risk, so that the Chalcans were told to wait. As the messengers were leaving with this cold comfort envoys arrived from Huexotzinco and Quauhquechollan. They had seen the signal pillars of smoke of the hostile allies, and had come to ask if they could be of service. The proposals came most opportunely.
The Huexotzincas and Quauhquechollans had long entertained a hatred of the Chalcans, as natives of an
Aztec province against whose forces they had often been arrayed, but Cortés represented the true state of affairs and convinced the respective envoys of the important service they could render themselves and their new sovereign, to whom all owed allegiance, by forgetting occurrences for which their oppressors were to blame, and to combine for mutual aid. His arguments were convincing, and both Huexotzinco and Quauhquechollan promised immediately to support the Chalcans with a large force.
