On December 20, 1598, Oñate learned of Zaldívar's death and after encouraging advice from the friars planned an attack in revenge as well to teach a lesson to other pueblos. Acomas requested help from other tribes to defend against the Spanish. Among the leaders were Gicombo, Popempol, Chumpo, Calpo, Buzcoico, Ezmicaio, and Bempol (a recruited Apache war leader). On January 21, 1599, Vicente de Zaldívar (Juan de Zaldívar's brother) reached Acoma with 70 soldiers. The Acoma Massacre started the next day and lasted for three days. On January 23, men were able to climb the southern mesa unnoticed by Acoma guards and breach the pueblo. The Spanish dragged a cannon through the streets toppling adobe walls and burned most of the village killing 800 people (decimated 20% of the 4,000 population) and imprisoning approximately 500 others. Almost all the remaining inhabitants were enslaved or left the town. The pueblo surrendered at noon on January 24. Zaldívar lost only one of his men. The Spanish amputated the right feet of men over 25 years old and forced them into slavery for 20 years. They also took males aged 12–25 and females over 12 away from their parents putting most of them in slavery for 20 years. The enslaved Acoma were given to government officials and various missions. Two other Indian men visiting Acoma at the time had their right hands cut off and were sent back to their respective Pueblos as a warning of the consequences for resisting the Spanish. On the north side of the mesa, a row of houses still retain marks from the fire started by a cannon during this Acoma War. (Oñate was later exiled from New Mexico for mismanagement, false reporting, and cruelty by Philip III of Spain.)
