King Emmanuel determined to take immediate advantage of the trade route opened to him by Dom Vasco da Gama's voyage. On March 9, 1500, a fine fleet of thirteen ships was despatched under the command of Pedro Alvares Cabral, well laden with merchandise, to trade with India. On his way out this Portuguese fleet was driven far to the westward, and to Cabral belongs the honour of discovering Brazil, which was eventually to become far more valuable to Portugal than the Indian trade. On leaving Brazil, Cabral followed the course taken by Dom Vasco da Gama, and with the help of pilots from Melinda anchored safely in the port of Calicut. At that place he established a factory or agency for the sale of the merchandise he had brought with him and for the purchase of Indian commodities, and then sailed for Cochin. But the Mopla merchants were still the declared {27} enemies of the Portuguese. They raised a riot in the city of Calicut, and Ayres Correa, the Portuguese agent, was killed with several of his associates. It is worthy of remark that this murderous attack was entirely the work of the Arab Moplas. The Hindu Zamorin showed no disinclination to trade with the Europeans; the Malabar Muhammadans, that is the natives who had been converted to Islám, did not share in the outrage, and one of their principal merchants even interfered to save the lives of Correa's children and of some of the Portuguese clerks. Cabral then loaded his ships at Cannanore and Cochin, where Hindu Rájás, inferior in power to the Zamorin, but not so much subject to Mopla influence, ruled, and after burning some of the Indian ships in the harbour of Calicut he returned to Lisbon in July, 1501. Cabral had not been so fortunate as Vasco da Gama, for he only brought back five out of the thirteen ships which he had taken with him. But, on the other hand, he did what Vasco da Gama had feared to do, and in spite of the fate of Ayres Correa and his associates, Cabral left a Portuguese factor with a considerable staff at Cochin to purchase goods for despatch to Portugal by the next fleet which should arrive. On the return of Cabral from India, King Emmanuel resolved to send once more to the East the famous captain who had discovered the direct sea route to India. It was obvious to the king that large profits were to be made by the Eastern trade, but at this early period he had formed no distinct idea as to the policy {28} he would pursue. On one point only he was resolved. It was quite certain that Portuguese agents would have to be left at the places of export if a prosperous trade was to be developed, and it was therefore necessary to give a severe lesson to the Zamorin of Calicut for the murder of the Portuguese factor at his capital. Adequate protection to Portuguese agents could only be given by maintaining a strong force in the Indian Seas. Vasco da Gama was therefore ordered to punish the Zamorin and to leave a squadron of ships for the defence of the Portuguese factors.
