The reasons for this failure are to be found in the internal causes of the Portuguese decline. The union with Spain brought their rivals into the Eastern seas, but it was their own weakness which let those rivals triumph. The primary cause of that weakness was the complete exhaustion of the Portuguese nation. Year after year this little country, which never exceeded 3,000,000 in population, sent forth fleets to the East, carrying sometimes as many as 3000 and 4000 soldiers. Of these men few ever returned to Europe. Many perished in battle, in shipwreck, or from the climate, and those who survived were encouraged to settle down and marry native women. During the whole of the sixteenth century Portugal was being drained of men, and those the strongest and bravest of her sons. In return she got plenty of wealth, but money cannot take the place of brain and muscle. Besides becoming exhausted {203} in quantity, the Portuguese in the East rapidly degenerated in quality. It was not only that Albuquerque's successors in supreme command were his inferiors; some of them proved worthy of their office; but the soldiers and sailors and officials showed a lamentable falling off. Brilliant courage was shown up to the siege of Goa in 1570. After that time it is difficult to recognise the heroic Portuguese of Albuquerque's campaigns. Albuquerque's imperial notions were set aside as impracticable, and interest in commerce and in Christian missions took the place of vast schemes of conquest and of empire. The later history of the Portuguese in Asia may be summed up in a rapid record of their disasters. In 1603 and 1639 the Dutch blockaded Goa. In 1656 they drove the Portuguese from Cannanore; in 1661 from Negapatam and Káyenkolam, the port of Quilon; in 1663 from Cranganore and Cochin. Nor were the Dutch victories confined to India; in 1619 they founded Batavia in the island of Java, and in 1640 they took Malacca and concentrated the whole trade of the Spice Islands at their new settlement. The Dutch were equally successful in Ceylon, which they completely controlled after the capture of Jaffnapatam in 1658. The English were but little later in the field: in 1611 Sir Henry Middleton defeated the Portuguese off Cambay, and in 1615 Captain Best won a great victory over the Portuguese fleet off Swally, the port of Surat. The Dutch and English agencies quickly covered the East, and soon after {204} the middle of the seventeenth century the Asiatic trade of Portugal had practically disappeared. What little commerce survived was in the hands of the Jesuits, and became finally extinct on the suppression of that body by the Marquis of Pombal in 1742.
