This first attempt was followed by the sack of the town and after having despoiled the citizens, they took their departure unmolested with a great booty. The tyranny of the late King had prepared the way for all these outrages. Whoever calls in foreign defensive assistance is no more than an oppressor who has more trust in the mercenaries he pays, than in the subjects he plunders, but he has the sad experience that his paid defenders often turn out to be only traitors. All countries in whose armies foreigners have predominated have only had transitory periods of prosperity, for the reason that those who have brought about their success, have also been the cause of their downfall. The neighbouring tribes wishing to profit by the troubles in the Kingdom, made an invasion. Their army came within three day's march of the capital, but peace had then been restored as the Japanese had taken their departure. The King of Siam collected his troops, and struck such terror into them that, they retreated precipitately without risking the issue of a battle. This Prince, with the assistance of the Portuguese, recaptured several provinces which had previously been seized by the Kings of Ava and Pegu, and, full of gratitude towards his brave auxiliaries, he offered the Port of Martaban to the King of Portugal as a base for his fleet. The ambassadors who made this offer to the Viceroy of Goa returned loaded with gifts. They were accompanied by a Dominican friar to whom the negociation was entrusted. They were received with every mark of distinction and concluded a treaty the terms of which were extremely advantageous to the Portuguese. This first success was the cause of a new embassy in 1621 which assisted the progress of the Faith. Some Franciscans were demanded by the King to preach the Gospel in his realm. He built them a church at his own expense and wished to make them wealthy, to which latter proposal they turned a deaf ear. Their disinterested motives of which the country furnished so few examples, increased the admiration which their other virtues had evoked.
