At this time Diego Calva arrived with one ship from Lisbon, and several others from Malacca, and in consequence of this addition to their strength, the Portuguese acted still more insolently than before, and so exasperated the governors of the province that they apprehended several of them, and even contrived to take the last arrived ship. At the commencement of hostilities Duarte Coello arrived from Malacca with two ships well manned and armed. The _Itao_, or Chinese admiral in these seas, attacked the Portuguese with fifty ships, and though he did them some damage, he was so severely handled by the artillery that he was forced to retire and to remain at some distance, keeping up a strict blockade. After matters had remained in this state for forty days, Ambrose del Rego arrived with two additional ships from Malacca, and the Portuguese determined upon forcing their way through the Chinese fleet. The battle on this occasion was very bloody; but in consequence of a gale of wind dispersing the Chinese fleet, the Portuguese were enabled to get away from the island of Tamou. The Itao revenged himself upon such of the Portuguese as had fallen into his hands, and particularly upon Thomas Perez and his companions, who were all slain, and their baggage robbed of the present intended for the emperor, and of all the commodities which Perez had purchased during his residence in China. Such was the profitableness of the China trade at this time, that Perez though only an apothecary of mean parentage, had by this time acquired 2000 weight of rhubarb, 1600 pieces of damask, 400 pieces of other silks, above 100 ounces of gold, 2000 ounces of silver, 84 pounds of loose musk, above 3000 purses or cods of that perfume, called _Papos_, and a great deal of other commodities.
