António de Abreu

António de Abreu (c. 1480 – c. 1514) was a 16th-century Portuguese navigator and naval officer. He participated under the command of Afonso de Albuquerque in the conquest of Ormus in 1507 and Malacca in 1511, where he got injured. Departing from Malacca in November 1511 with three ships, in an exploratory voyage to the 'Spice Islands' of Maluku, he led the first European expedition to reach Timor and the Banda Islands, in Indonesia, in 1512.

On 25 July 1511, during the conquest of Malacca, António de Abreu led the Chinese junk that went up the Malacca River at high tide, allowing the Portuguese contingent to land and conquer the city in August. Severely wounded in the face, having lost some teeth and tongue, he refused the proposal from Albuquerque to relieve the command.

In November that year, after sending ambassadors to Pegu and Siam one month before leaving Malacca, Albuquerque trusted Abreu with the command of a fleet of three ships sailing in search of the "Spice Islands". Abreu was captain-major in the ship Santa Catarina, the deputy commander was Francisco Serrão on the ship Sabaia, and a third vessel, a caravel, was under command of Simão Afonso Bisagudo, having as pilot Francisco Rodrigues, an able cartographer who wrote about this expedition. With a crew of 120 Portuguese and 60 slaves they were guided by Malay pilots, recruited to guide them through Java, the Lesser Sunda Islands and Ambon Island to the Banda Islands, where they arrived in early 1512. They remained there for about a month, buying and filling their ships with nutmeg and cloves. Abreu then sailed to Amboina whilst his deputy commander Serrão stepped forward to the Moluccas but sank, ending in Ternate. Occupied with fighting elsewhere in the archipelago, such as Ambon and Ternate, he returned only in 1529.

Abreu returned to Malacca in December 1512, from where he departed for India with Fernão Pires de Andrade in January 1513, then sailing for Portugal. He died in Azores, before reaching continental Portugal.
