Diego Miruelo, ca. 1516 . This exploratory expedition is very poorly documented, but may have been launched from Cuba in search of slaves along the western coast of Florida. The expedition documented and named at least one large bay along the northern Gulf coastline, though several later expeditions had great difficulty in identifying it. The following year Juan Ponce de León was engaged in a lawsuit against Cuban governor Diego Velázquez del Cuellar for having allowed 300 Florida Indians to be captured and brought illegally to Cuba, and this might possibly have resulted from Miruelo's expedition.
