Battle of Las Salinas

The Battle of Las Salinas was a military conflict and decisive confrontation between the forces of Hernando and Gonzalo Pizarro against those of rival conquistador Diego de Almagro, on April 26, 1538, during the Conquest of Peru. Both camps claimed to represent the authority of the Spanish Crown; Pizarro's forces controlled the province of Nueva Castilla, and those of Almagro, Nueva Toledo.
