A fleet of fifteen ships departed for the coast of India in 1506 under the command of Tristão da Cunha, an admiral who had previously served in the Third Italian War. This voyage resulted in the discovery of a remote archipelago in the south Atlantic Ocean, which the commander named after himself before sailing toward his strategic military objectives.
Military Service in Italy
Before his maritime endeavors, da Cunha served under the Castilian general Gonzalo Fernández de Córdoba during the Third Italian War. He participated in the Battle of Cerignola and was appointed to conduct the funeral rites for the French general Louis d'Armagnac, Duke of Nemours. During this period, he held command of the fortification at Roca Guillerma, located between Salerno and Gaeta, where he was captured by French forces before eventually securing his release.

In 1506, da Cunha received a commission to lead a fleet toward Africa and India alongside his cousin, Afonso de Albuquerque. Upon reaching the Mozambique Channel, they rescued the captain João da Nova and his ship, the Flor de la mar. Following successful engagements against local cities, the fleet targeted the island of Socotra. In 1507, da Cunha and Albuquerque captured the port of Suq, where the architect Tomás Fernandes oversaw the construction of the Forte de São Miguel de Socotorá. The garrison struggled with famine and sickness, leading the Portuguese to abandon the site by 1511. During this same deployment, da Cunha conducted raids in Northern Madagascar and provided military relief to the Portuguese garrison during the Siege of Cannanore on 27 August.
Diplomacy and the Papal Embassy
Appointed as the ambassador for King Manuel I, da Cunha traveled to Rome in 1514 to present the territorial gains of the Portuguese Empire to Pope Leo X. The delegation, which included secretary Garcia de Resende, arrived in the city with an extravagant procession on 12 March. The display featured diverse wildlife, including leopards, parrots, and an elephant named Hanno, which performed for the Pope at the Castel Sant'Angelo. By April 1515, the mission concluded with the Pope issuing a bull in recognition of the Portuguese efforts. Da Cunha returned to Portugal, where he served on the Privy Council. He died in 1540 and was interred at the convent of Nossa Senhora da Encarnação in Olhalvo.
