After the departure of Sequeira for Cochin, Aga Mahomet who commanded the fleet belonging to Malek Azz did every thing in his power to hinder the construction of the fort. To secure the entrance of the river, the Portuguese had erected a redoubt or bulwark on the side opposite the fort, which was commanded by Pedro Vaz Permeo with a garrison of thirty men. Mahomet sent 300 of his men by night to surprise this bulwark, but they were so valiantly opposed by the small garrison, though the captain and several men were slain, that they maintained their ground till relieved by Ruy Vaz Pereira with a reinforcement of sixty men, who put the enemy to flight after having lost a hundred men. By this success the enemy were much daunted, and particularly one Sheikh Mamud, a great man in the city, who pretended to be a friend to the Portuguese, yet did every thing in his power secretly to molest them. On occasion of the defeat of Aga Mahomet, the sheikh sent to congratulate Antonio Correa; who well knowing his treachery, sent him back the heads of his messengers, and hung up their bodies along the shore. The sheikh was astonished at this act, and now proceeded to open hostilities, encouraging Aga Mahomet to persevere in the blockade, giving him intelligence that the Portuguese were in want of ammunition. But Don Luis de Menezes arrived with reinforcements and a supply of ammunition and provisions, to whom Correa resigned the command. Don Duarte de Menezes entered upon the government of India on the 22d of January 1522, John III. being then upon the throne of Portugal. Having dispatched his predecessor with the homeward trade, and sent off commanders to the different establishments in India, he began to experience the bad effects of Sequeira having appointed Portuguese officers to the custom-house at Ormuz; as he received advice that the Moors of that place had taken arms and killed some men, and had even besieged the fort. He immediately sent his brother with relief, and appointed Simon de Andre to command at Chaul, who began his career by taking two Turkish gallies, and gaining a victory over the people of Dabul, by which that city was reduced to pay tribute. Malek Azz was terrified by these successes, and withdrew his fleet from before Chaul.
