On April 5, 1506, Tristão da Cunha and Affonso de Albuquerque set sail from the Tagus. Differences between the two commanders soon appeared. Albuquerque's own pilot had fled to Castile, after murdering his wife, and, since Tristão da Cunha refused to give him another pilot, the future Governor of Portuguese India had to navigate his own vessel. But the difference between them was not due alone to this personal dispute--the two men were of essentially different temperaments. Tristão da Cunha was before all things an explorer; his hope was to discover fresh countries for his royal master. Albuquerque was, on the other hand, a statesman, fully impressed with the importance of the mission on which he was sent and determined to subordinate {50} everything else to it. This radical difference soon made itself felt. When the united fleet reached Mozambique, news was brought to the principal commander by Ruy Pereira Coutinho that he had discovered an island which seemed rich in cloves and other spices. This island he had named the Island of San Lourenço, and it is the island now known as Madagascar. Tristão da Cunha, in spite of the remonstrances of Albuquerque, who refused to accompany him, went off at once to explore the new land. But, after a perilous voyage, he abandoned his purpose and joined Albuquerque to carry out the first aim of the expedition, the conquest of the island of Socotra. As they made their way north along the African coast, they paid a visit to Melinda and renewed the treaty of friendship between the Chief of that place and the Portuguese. The Chief of Melinda told the Portuguese captains that the Chiefs of Mombassa and Angoja caused him much annoyance for his friendship with the Portuguese, and begged that they would take vengeance on them. In accordance with this request, the Portuguese sacked and burnt the city of Angoja, the Chief of which place was 'a Moorish merchant who came from abroad, but as he was very rich he had made himself lord of all that land.'[1] The fleet then proceeded to Braboa, or Brava, where the Muhammadan ruler refused to acknowledge the supremacy of or pay tribute to the King of Portugal. {51} The place was therefore attacked and burnt by the Portuguese sailors. In this engagement Tristão da Cunha was wounded, and at his own request was knighted by Affonso de Albuquerque on the spot where he had received his wound.
