Almeida's successor, who had the eye of Alexander the Great for strategic points and commercial centres, was convinced that sea-power, at six months from home, rests on the occupation of seaports, and he carried the forward policy so far that Portugal possessed fifty-two establishments, commanding 15,000 miles of coast, and held them, nominally, with 20,000 men. Almeida's victory had broken the power of the Moors. Albuquerque resolved to prevent their reappearance by closing the Persian Gulf and the Red Sea. With Aden, Ormuz, and Malacca, he said, the Portuguese are masters of the world. He failed in the Red Sea. When Socotra proved insufficient, he attacked Aden, and was repulsed. There was a disconcerting rumour that no Christian vessel could live in the Red Sea, as there was a loadstone that extracted the nails. Albuquerque succeeded in the Persian Gulf, and erected a fortress at Ormuz, and at the other end of the Indian world he seized Malacca, and became master of the narrow seas, and of all the produce from the vast islands under the equator. He made Goa the impregnable capital of his prodigious empire, and the work that he did was solid. He never perceived the value of Bombay, which is the best harbour in Asia, and did not see that the key of India is the Cape of Good Hope. His language was sometimes visionary. He beheld a cross shining in the heavens, over the kingdom of Prester John, and was eager for an alliance with him. He wished to drain the Nile into the Red Sea. He would attack Mecca and Medina, carry off the bones of the prophet, and exchange them for the Holy Sepulchre. The dependency was too distant and too vast. The dread proconsul in his palace at Goa, who was the mightiest potentate between Mozambique and China, was too great a servant for the least of European kings. Emmanuel was suspicious. He recalled the victorious Almeida, who perished on the way home; and Albuquerque was in disgrace, when he died on his quarter-deck, in sight of the Christian city which he had made the capital of the East.
