Ovando sent Andrés Morales to explore completely the Hispaniola island. Morales made the most complete map of the island. Sebastián de Ocampo was sent to find out if Cuba was an island or part of the continent; after 8 or 10 months, Ocampo came back with the information that Cuba was an island. In 1508, Juan Ponce de León was sent with 50 men to conquer the island of San Juan (now the island of Puerto Rico).
