The Persian Gulf, which intervenes between Arabia and Persia, takes its name from the latter, as the more noble country. This famous gulf begins at Cape Jasques or Carpela, in lat. 26° N. and ends at the mouth of the river Euphrates, having many cities, rivers, woods, and islands along its northern or Persian shores. On the other or Arabian shore, beginning at Cape Mozandan or Musaldon, named Assaborum by the ancients, and ending where it meets the other side at the Euphrates, there are only four towns. One of these, Catifa or Al Katif, is opposite the island of Bahrayn, where is the pearl-fishery. This island is 30 leagues in circumference, and seven leagues long, and is 110 leagues from Ormuz. The principal product of this island is tamarinds, but it has likewise all the other fruits that grow in Spain. The largest town is of the same name with the island, besides which there are about 300 villages, inhabited by Arabs and Moors161. The air is very unhealthy. The pearls found here, though not in such abundance, are more valuable than those of Ceylon in India, or of Hainan in China. On the continent of Arabia, opposite to Bahrayn is the city of Lasah162, of which Mocrim was king.

Having formed his dispositions of attack, Correa landed at the head of 170 Portuguese, giving orders to Reis Xarafo to send assistance wherever he might see it necessary. Ayres Correa, the brother of the Portuguese commander, led the van or forlorn hope of fifty men, all of whom were knee deep in water. The Portuguese assaulted the trenches with great bravery, and were opposed with much resolution by the enemy, headed by the king; and after some time both parties were so much fatigued by the heat as to be under the necessity of taking some respite, as by mutual consent. After a short rest, the attack was renewed, and the king being shot through the thigh, of which wound he died six days afterwards, his men lost heart, and great numbers of them being killed and wounded, they fled leaving a complete victory to the Portuguese. During the whole engagement, Reis Xarafo looked on from his vessel as an unconcerned spectator; but when afterwards the body of the deceased king was carried over to Lasah for interment, he went there and cut off his head, which he sent to Ormuz. In this engagement the Portuguese had seven men killed and many wounded, but the island was effectually reduced. For this exploit, Correa had the title of Bahrayn added to his name, and was authorized to bear a kings head in his coat of arms, which is still borne by his descendents.

In this same year 1521, the zamorin of Calicut made war against Cochin at the head of 200,000 men; and although only forty Portuguese were in the army of Cochin, and but thirty of these armed with muskets, the enemy retired in dismay. At this time likewise Diego Fernandez de Beja, who had been left before Diu, came to join Sequeira at Ormuz, having been attacked by some vessels belonging to Malek Azz, whose double dealing was now apparent. To prevent certain frauds that had been practised by the native officers of the customs at Ormuz, Sequeira thought proper to appoint Portuguese officers in that charge, which so exasperated the natives that they endeavoured to shake off the yoke, as will appear hereafter.

Being determined to resume the plan of establishing a fort at Diu, Sequeira sent back Beja to that place with four stout vessels, with orders to hinder all ships from entering the port. Beja executed these orders for some time effectually, and even took some vessels; but Malek Azz came against him with a number of ships well armed with cannon, sunk one of the Portuguese galleons and did much damage to the others which were becalmed; but on the wind springing up, the vessels of the enemy were forced to retire. While Sequeira was on his voyage from Ormuz against Diu, he captured a vessel by the way, and divided the Moorish crew among his ships. Those who were put on board the ship commanded by Antonio Correa, set fire to the powder-room, by which the poop was blown into the air and the vessel sunk; in which miserable catastrophe the brave conqueror of Bahrayn perished. 163. Owing to these misfortunes, Sequeira desisted from the enterprise against Diu, and went to Chaul where he found Ferdinando Camelo, who had brought permission from Nizam al Mulk to build a fort at that place, chiefly to favour the importation of horses for his own use, as that trade was then confined to Goa. The building of the fort was accordingly begun without delay. As Malek Azz suspected that the establishment of the Portuguese at this place might lessen greatly the trade of Diu, he made his appearance off Chaul with above fifty vessels, and sunk a large Portuguese ship just come from Ormuz. Azz continued to blockade the port of Chaul for three weeks, doing much damage to the squadron which was opposed to him; yet the construction of the fort went on with all diligence. Learning that his successor was arrived at Cochin, which rendered his presence necessary at that place, Sequeira forced his way through the enemy, leaving his nephew Henry de Menezes to command the fort, and Antonio Correa with the charge of the ships.

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.

As formerly mentioned, the late governor Sequeira had appointed Portuguese officers to collect the revenue of Ormuz, which in fact had been done contrary to his own private judgment, but by command of the king of Portugal. These officers conducted themselves oppressively to the natives, from whom they made many undue exactions to satisfy their own cupidity, and behaved to them with much insolence and violence, even forcing from them their wives and daughters. Unable to endure these oppressions, the inhabitants of Ormuz and its dependencies formed a conspiracy against the Portuguese, and broke out into open insurrection against them suddenly at Ormuz, Bahrayn, Muscat, Kuriat, and Zoar164, all in one night by previous concert, by a private order from the king of Ormuz. This attack was so sudden and well concerted, that above 120 of the Portuguese were slain on that night, and one Ruy Boto was put to the torture by the Moors in defence of the faith. The Portuguese at Ormuz, where Don Garcia Coutino then commanded, exerted themselves as well as they could to defend themselves, and secured the ships which happened to be at that place under the protection of the fort, which was immediately besieged. Of these events immediate intelligence was sent by Don Garcia to Cochin and other places for relief, fearing he might be constrained to surrender for want of provisions and water; and in fact two of the Portuguese vessels were burnt by the Moors under the guns of the fort.
