Alonso Valiente first traveled to the New World with Cristóbal Colón's (Christopher Columbus') last expedition to the continent.
Valiente was one of the conquerors of Higüey in today's Dominican Republic and Borinquen (named by Cristóbal Colón San Juan Bautista) in what is now known as Puerto Rico[1][2] He remained there from 1509 to 1521.
The inhabitants of these islands told that the crew of a vessel coming from today's Cuba had captured and enslaved more than sixty people.
However, they learned that the ship was originally sent from Santo Domingo with other purposes, but the captain changed plans during the mission, realizing that he could capture slaves and make a profit.
[1] Valiente held a number of appointive offices in addition to acting as secretary to his relative Hernán Cortés.

This suspicion arose when she was urged to marry another man by the colonial factor, fearing that Valiente and all of the participants in one of Cortés' expeditions had died.
When the factor understood that he had made a mistake, he issued an apology and decided to ask every gentleman in the colony to ride their horses in the streets, to honor Juana de Mancilla.
This year, Alonso Valiente was also referred to the Holy Inquisition for having said that mere fornication was not a mortal sin.
[1] Together with Juan Altamirano, Alonso Valiente stayed in Mexico during Cortés' first trip to Spain.
Alonso took Juan to Spain and eventually allowed him to travel to South America, so that he could also try his chances as a conqueror.
[9] Alonso Valiente is also known for having been the first owner of La Casa del Conde (the count's house) in one of his encomiendas in Tecamachalco.
