Camoens first took part in an expedition against the King of Pimenta, and in the following year (1554) he joined another directed against the Moorish pirates on the coast of Africa. The scenes of drunkenness and dissoluteness which he witnessed in Goa inspired him with a number of satirical poems, by which he drew upon himself much enmity and persecution. In 1556 his three-years' term of service expired; but though ardently longing for his beloved native land, he remained in Goa, influenced either by his bent for the soldier's life or by the sad news of the death of Donna Catharina de Athaide in that year. He was ordered to Macao in China, to the lucrative post of commissary for the effects of deceased or absent Portuguese subjects. There, in the quietude of a grotto near Macao, still called the Grotto of Camoens, the exiled poet finished the first six cantos of his great epic 'The Lusiads.' Recalled from this post in 1558, before the expiration of his term, on the charge of malversation of office, Camoens on his return voyage to Goa was shipwrecked near the mouth of the Me-Kong, saving nothing but his faithful Javanese slave and the manuscript of his 'Lusiads'--which, swimming with one hand, he held above the water with the other. In Cambodia, where he remained several months, he wrote his marvelous paraphrase of the 137th psalm, contrasting under the allegory of Babel (Babylon) and Siam (Zion), Goa and Lisbon. Upon his return to Goa he was cast into prison, but soon set free on proving his innocence by a public trial. Though receiving, in 1557, another lucrative employment, Camoens finally resolved to go home, burning with the desire to lay his patriotic song, now almost completed, before his nation, and to cover with honor his injured name. He accepted a passage to Sofala offered him by Pedro Barreto, who had become viceroy of Mozambique in that year. Unable to refund the amount of the passage, he was once more held for debt and spent two years of misery and distress in Mozambique, completing and polishing during this time his great epic song and preparing the collection of his lyrics, his 'Parnasso.' In 1559 he was released by the historian Diogo do Couto and other friends of his, visiting Sofala with the expedition of Noronha, and embarked on the Santa Clara for Lisbon.
