 De Mafra goes back to the sea in 1531, and sails to Central, and South America.The governor of Guatemala, Pedro de Alvarado, in a letter written on November 20, 1536, tells the emperor he had hired the services of de Mafra as pilot, who is considered as one of the best sailors due to his experiences with the Magellan voyage.It's not clear where the expedition went but most scholars believe the fleet went to Peru.
