These ideas deserve notice both as illustrating the grandiose conceptions of Albuquerque, and his skill in taking advantage of dissensions among the foes of the Christian religion. To him doubtless it mattered not whether the Muhammadans he attacked were Shiahs or Sunís--all alike were infidels; but he was perfectly ready to make use of the one sect against the other. He calmly put on one side the demand of the Persian ambassador that the Shiah form of Muhammadanism should be proclaimed in Goa, and that Ismáil Sháh's money should pass current, but he nevertheless dismissed the ambassador with fair words. Albuquerque was soon distracted from questions of general policy by the advance of the King of Bijápur upon the island of Goa with 60,000 men. As had {79} happened at Ormuz, his captains did not share his views. They declared it to be impossible to defend Goa, and strongly resented being engaged in the hard work of building walls instead of in the more lucrative business of collecting cargoes for Portugal. The news of the advance of Yusaf Adil Sháh increased the reluctance of the captains to remain, but Albuquerque nevertheless refused to evacuate Goa. The Muhammadan king made overtures to him and promised to cede to the Portuguese any other port in his dominions except Goa, and it was even hinted that Goa itself would be given up, if Albuquerque would surrender Timoja, who was looked on as a traitor to his country. This proposition it need hardly be said was rejected with scorn. Eventually, whether from the unwillingness of the Portuguese captains or from sheer impossibility of defence, Yusaf Adil Sháh's army made its way into the island of Goa on May 17, 1510. The Portuguese at first hoped to hold the citadel of Goa; but finding the position untenable, Albuquerque withdrew his men to their ships, after setting fire to the arsenal and beheading 150 of the principal Muhammadan prisoners whom he had in his possession. He then dropped down the river with his fleet, but was unable to cross the bar owing to the state of the weather. For nearly three months the Portuguese fleet remained at anchor at the mouth of the harbour of Goa. It was one of the most critical periods in Albuquerque's life, and during it he exhibited the {80} highest qualities of a commander. At their anchorage, the Portuguese found themselves exposed to the fire of the King of Bijápur's artillery, mounted in the castle of Panjim, which had been abandoned after the capture of Goa. Albuquerque therefore decided to make a night attack upon this position. The fight was a fierce one. Several of the Portuguese were killed, and it was with difficulty that the garrison was expelled on June 14, 1510.
