Two junk masters were seized, and the Chinese population was menaced; therefore they prepared for their own defence, and then opened the affray, for which the Government was secretly longing, by killing a Spaniard in the market-place. Suddenly artillery fire was opened on the Parian, and many of the peaceful Chinese traders, in their terror, hanged themselves; many were drowned in the attempt to reach the canoes in which to get away to sea; some few did safely arrive in Formosa Island and joined Koxinga's camp, whilst others took to the mountains. Some 8,000 to 9,000 Chinese remained quiet, but ready for any event, when they were suddenly attacked by Spaniards and natives. The confusion was general, and the Chinese seemed to be gaining ground; therefore the Governor sent the Ambassador Riccio and a certain Fray Joseph de Madrid to parley with them. The Chinese accepted the terms offered by Riccio, who returned to the Governor, leaving Fray Joseph with the rebels; but when Riccio went back with a general pardon and a promise to restore the two junk masters, he found that they had beheaded the priest. A general carnage of the Mongols followed, and Juan de la Concepcion says [36] that the original intention of the Spaniards was to kill every Chinaman, but that they desisted in view of the inconvenience which would have ensued from the want of tradesmen and mechanics. Therefore they made a virtue of a necessity, and graciously pardoned in the name of His Catholic Majesty all who laid down their arms. Riccio returned to Formosa Island, and found Koxinga preparing for warfare against the Philippines, but before he could carry out his intentions he died of fever. The chiefs successor, of a less bellicose spirit, sent Riccio a second time to Manila, and a treaty was agreed to, re-establishing commercial relations with the Chinese. Shortly after Koxinga's decease a rebellion was raised in Formosa; and the Island, falling at length into the hands of a Tartar party, became annexed to China under the new dynasty. Then Riccio was called upon to relate the part he had taken in Koxinga's affairs, and he was heard in council. Some present were in favour of invading the Philippines in great force because of the cruel and unwarranted general massacre of the Chinese in cold blood; but Riccio took pains to show how powerful Spain was, and how justified was the action of the Spaniards, as a measure of precaution, in view of the threatened invasion of Koxinga. The Chinese party was appeased, but had the Tartars cared to take up the cause of their conquered subjects, the fate of the Philippines would have been doubtful.
