The Battle of Otumba was fought between the Aztec and allied forces led by the Cihuacoatl Matlatzincátzin and those of Hernán Cortés made up of the Spanish conquerors and Tlaxcalan allies. It took place on July 7, 1520, in Temalcatitlán, a plain near Otumba during the development of the Conquest of the Aztec Empire. The result of the battle was a successful defense for the Spanish, which allowed Cortés to reorganize his army, having suffered casualties a few days before in the episode known as La Noche Triste. A year later, by reinforcing his army with new men and supplies, and starting an alliance with the Tlaxcala Confederacy, Cortés found a way to reenter Tenochtitlan.
