Barreto served in the East Indies, was governor of Portuguese India, and was probably instrumental in exiling Lus de Cames to Macau after the poet had published criticisms of Portuguese administration in India. In 1569 Barreto was entrusted by King Sebastian of Portugal with an expedition to the empire of Mwene Matapa in southeastern Africa to assert Portuguese authority over the area, capture the gold mines of Manica, and avenge the murder of a missionary. Barreto took the Zambezi River valley route (1572); the following year the expedition was repeated, but Barreto became mortally ill and died at Sena.
