On the 15th of October, the Aracan fleet was observed coming down the river to attack, so numerous that they could not be counted.  The foremost vessel was a Dutch pink, and many of the other vessels were commanded by Hollanders.  All that could be seen appeared full of men well armed and equipped, and seemed a prodigious overmatch for the small number the Portuguese had to oppose them, as besides the galliot sent to Sundiva another had been dispatched in search of the pink, so that only 12 galliots remained and the fliboat.  The Dutch pink fired the first gun, and then the fight began with great fury, the Portuguese galliots bravely advancing against the vast hostile fleet.  Four of the galliots got before the rest, and in the very beginning of the action their captains and many of their men were slain, but the other eight came up to their rescue, and great execution was done among the enemy, many of whom were drowned by oversetting their vessels in their haste to escape from the destructive fire of the Portuguese.  The battle raged the whole day, but the enemy drew off in the evening, thinking that a reinforcement was coming to the Portuguese, as they saw the galliot approaching which had been sent in search of the pink.  In this engagement the Portuguese lost 25 men of note besides others.

Next morning the pink joined the fleet, on board of which all the wounded men were put, and those that were fit for service in that vessel were distributed among the others.  Roxo now resolved to remain at anchor at the mouth of the river till Gonzalez came to join him, and then to attack the enemy.  At length Gonzalez made his appearance, with 50 vessels well manned and equipped, and on being told the orders of the viceroy and what had been already done, he expressed much displeasure at the viceroy for giving such orders, and at Roxo for imprudently fighting before his arrival.  About the middle of November:  the combined fleets sailed up the river and discovered the vast fleet of Aracan at anchor in a well chosen situation, where it was resolved immediately to attack them.  Roxo took half of the ships belonging to Gonzalez under his immediate command, giving Gonzalez half of these he had brought from Goa, so as to make two equal squadrons.  Thus arranged they advanced against the enemy, firing against those vessels they could reach, but none of the enemy ventured to advance.  The king of Aracan viewed the engagement from the shore to encourage his people, and caused the heads of such as fled to be cut off and exposed on spears as a terror to the rest.  About noon when the heat of the sun was so great as to scorch the Portuguese; the Aracan ships came on in three numerous squadrons.  Sebastian Gonzalez put to flight those of the enemy that were opposed to him, and the Portuguese pink compelled that belonging to the Hollanders to draw off.  On that side where Roxo commanded there was much slaughter on both sides without any evident superiority;
