Hernando Cortes had come out to Cuba when he was nineteen, and that was fifteen years ago. Much had been reported concerning an emperor in a country to the west, who ruled over a vast territory inhabited by copper-colored people rich in gold, who worshiped idols. Cortes had observed that Indian tribes, like schoolboys, were apt to divide into little cliques and quarreling factions. If the subject tribes did not like the Emperor, and were jealous of him and of each other, a foreign conqueror had one tool ready to his hand, and it was a tool that Cortes had used many times before. The people of this coast, however, were not at all like the gentle and childlike natives Colon had found. From the rescued captive Aguilar, the commander learned much of their nature and customs. On his first attempt to land, his troops encountered troops of warriors in brilliant feathered head-bands and body armor of quilted white cotton. They used as weapons the lance, bow and arrows, club, and a curious staff about three and a half feet long set with crosswise knife-blades of obsidian. Against poisoned arrows, such as the invaders had more than once met, neither arquebus nor cannon was of much use, and body armor was no great protection, since a scratch on hand or leg would kill a man in a few hours. After some skirmishing and more diplomacy, at various points along the coast, Cortes landed his force on the island which Grijalva had named San Juan de Ulloa, from a mistaken notion that Oloa, the native salutation, was the name of the place. The natives had watched the "water-houses," as they called them, sailing over the serene blue waters, and this tribe, being peaceable folk, sent a pirogue over to the island with gifts. There were not only fruits and flowers, but little golden ornaments, and the Spanish commander sent some trinkets in return. In endeavoring to talk with them Cortes became aware of an unusual piece of luck. Aguilar did not understand the language of these folk. But at Tabasco, where Cortes had had a fight with the native army, some slaves had been presented to him as a peace-offering. Among them was a beautiful young girl, daughter of a Mexican chief, who after her father's death had been sold as a slave by her own mother, who wished to get her inheritance. During her captivity she had learned the dialect Aguilar spoke, and the two interpreters between them succeeded in translating Cortes's Castilian into the Aztec of Mexico from the first. The young girl was later baptized Marina. There being no "r" in the Aztec language the people called her Malintzin or Malinche,--Lady Marina, the ending "tzin" being a title of respect. She learned Castilian with wonderful quickness, and was of great service not only to Cortes but to her own people, since she could explain whatever he did not understand.
