Whatever his intentions, it is certain that Phaulcon carried his point, and an embassy was sent to the court of Louis XIV. In return the Chevalier de Chaumont, accompanied by a considerable retinue, and bearing royal gifts and letters, was despatched to Siam, where he arrived in September, 1685, and was splendidly received. Phaulcon was, of course, foremost among the dignitaries; the shipwrecked adventurer, who had risen from the position of common sailor to the post of premier in a rich and thriving realm, found himself receiving on terms of equality and in a style of magnificence that, even to European eyes, seemed admirable, the ambassador of the most illustrious king in Europe. Whether his loyalty to the sovereign whom he was bound to serve was always quite above the suspicion of intrigue with the French is more than doubtful. He greatly desired on his own behalf to effect the conversion of the king to Catholicism, and did what he could to support the arguments of the French envoy to this end. But the king, who was a shrewd man, refused to abandon the religion of his ancestors for that of these designing foreigners.
"Phaulcon had long thought," says the Père d'Orléans, "of bringing to Siam Jesuits who, like those in China, might introduce the Gospel at court through the mathematical sciences, especially astronomy. Six Jesuits having profited by so good an occasion as that of the embassy of the Chevalier de Chaumont to stop in Siam on their way to China, M. Constance upon seeing them begged that some might be sent to him from France; and for this especial object Father Tachard, one of the six, was requested to return to Europe." This was really the first step in Phaulcon's ruin; for, aware that his master could not in this way encourage the Christians without incurring the hatred of both the Buddhists and Mohammedans in the kingdom, he conceived the plan of begging Louis for some French troops ostensibly to accompany and support the missionaries, but practically to sustain his influence by force, and in the event of defeat to hand the country over to France. Three officers returned with M. de Chaumont and effected a treaty whereby Louis promised to send some troops to the Siamese king, "not only to instruct his own in our discipline, but also to be at his disposal according as he should need them for the security of his person, or for that of his kingdom. In the mean time the king of Siam would appoint the French soldiers to guard two places where they would be commanded by their own officers under the authority of this monarch." The troops and a dozen missionaries set out under Father Tachard's charge in 1686.
But ere they arrived trouble was brewing in Siam. "The Mohammedans," says the historian, "had long flattered themselves with the hope of inducing the king and people of Siam to accept the Koran; but when they saw the monarch thus closely allying himself with Christians, their fears were greatly excited; and the great difference which had been made between the French and Persian ambassadors, in the honors shown them in their audiences with his majesty, had so much increased the apprehensions of the infidels that they resolved to avert the apprehended misfortune by attempting the life of the king. The authors of this evil design were two princes of Champa and a prince of Macassar, all of them refugees in Siam, where the king had offered them an asylum against some powerful enemies of their own countries. A Malay captain encouraged them by prophecies which he circulated among the zealots of his own sect, of whom he shortly assembled a sufficient number to carry out the conspiracy, had it not been discovered; which, however, it was"—and promptly suppressed by the minister, to his great credit and honor at court. Phaulcon then was at the pinnacle of his power when the Frenchmen landed, an audience was granted and ratifications exchanged.
"M. Constance had already so high an esteem for our great king [Louis], and the king of Siam, his master, had entered so entirely into his sentiments, that this sovereign, thinking the French troops were not sufficiently near his person, determined to ask from the king, in addition to the troops already landed, a company of two hundred body-guards. As there was much to arrange between the two monarchs for the establishment of religion, not only in Siam, but in many other places where M. Constance hoped to spread it, they resolved that Father Tachard should return to France, accompanied by three mandarins, to present to his majesty the letter from their king; and that he should thence proceed to Rome, to solicit from the Pope assistance in preserving tranquillity and spreading Christianity in the Indies.
"Father Tachard, having received from the king and his minister the necessary orders, left his companions under the direction of M. Constance, and quitted Siam, accompanied by the envoys-extraordinary of the king, at the beginning of the year 1686. He reached Brest in the month of July in the same year.
"Never was negotiation more successful. Occupied as was the king in waging war with the greater part of Europe, leagued against him by the Protestant party, he made no delay in equipping vessels to convey to the king of Siam the guards which he had requested."
It is certainly not surprising that some of the Siamese noblemen should have looked with suspicion on the extraordinary measures which Phaulcon had inaugurated. With a French military force in possession of some of the most important points in the kingdom, and with the Roman Catholic religion securing for itself something like a dominant establishment, it is no wonder that conspiracies against the authors of the new movement should be repeated and ultimately successful. The king had no male heir; and it seemed to a nobleman named Pitraxa that the succession might as well come to him as to the foreigner who had already risen to such a dangerous authority. This time the conspiracy was more audaciously and triumphantly carried out. The king, who was beginning to grow old and infirm, was taken sick, and during his illness Pitraxa got possession of the royal seals, and by means of them secured supplies of arms and powder for the furtherance of his designs. The crisis rapidly approached. Phaulcon determined to arrest the chief conspirator, but was for once outwitted. The French forces which he summoned to his assistance were intercepted and turned back by a false report. Pitraxa made himself master of the palace, of the person of the king, and of all the royal family. It was evident to Phaulcon that the end had come. His resolution was taken accordingly.
"Having with him a few Frenchmen, two Portuguese, and sixteen English soldiers, he called these together, and, with his confessor, entered his chapel that he might prepare for the death which appeared to await him; whence passing into his wife's chamber, he bade her farewell, saying that the king was a prisoner, and that he would die at his feet. He then went out to go direct to the palace, flattering himself that with the small number of Europeans who followed him, he should be able to make his way through the Indians, who endeavored to arrest him, so as to reach the king. He would have succeeded had his followers been as determined as himself; but on entering the first court of the palace, he was suddenly surrounded by a troop of Siamese soldiers. He was putting himself into a defensive attitude when he perceived that he was abandoned by all his suite except the French, so that the contest was too unequal to be long maintained. He was obliged to yield to the force of numbers, and he and the Frenchmen with him were made prisoners and loaded with irons."
It remained for the usurper to rid himself of the French soldiers, who were still in possession of the two most considerable places in the country. Under a false pretext he won over to himself, temporarily, the commander of the French forces. "Upon this, six French officers who were at court, finding their safety endangered, resolved to leave and retire to Bangkok. They armed themselves, mounted on horseback, and under pretence of a ride, easily escaped from the guard Pitraxa had appointed to accompany them. It is true that, for the one they had got rid of, they found between Louvô and the river troops at different intervals, which, however, they easily passed. On reaching the river they discovered a boat filled with talapoins, which they seized, driving away its occupants. As, however, they did not take the precaution of tying down the rowers, they had the vexation of having them escape under cover of the night, each swimming away from his own side of the boat. Compelled to row it themselves, they soon became so weary that they determined to land, and continue their journey on foot. This was not without its difficulties, as the people, warned by the talapoins whose boat had been seized, and by the fugitive rowers, assembled in troops upon the riverside, uttering loud cries. Notwithstanding this, they leaped out, and gained the plains of Ayuthia, where, most unfortunately, they lost their way. The populace still followed them, and though not venturing to approach very near, never lost sight of them and continued to annoy them as much as possible. They might, after all, have escaped, had not hunger compelled them to enter into a parley for a supply of provisions. In answer, they were told that they would not be listened to until they had laid down their arms. Then these cowardly wretches, instead of furnishing them with provisions, threw themselves upon them, stripped them, and carried them bound to Ayuthia, whence they were sent back to Louvô most unworthily treated. A troop of three hundred Mohammedans, which Pitraxa on learning their flight sent in pursuit of them, and which met them on their return, treated them so brutally that one named Brecy died from the blows they inflicted. The rest were committed to prison on their arrival at Louvô.
"From this persecution of the French fugitives, the infidels insensibly passed to persecuting all the Christians in Siam, as soon as they learned that M. Desfarges was on the road to join Pitraxa; for from that time the tyrant, giving way to the suspicions infused by crime and ambition, no longer preserved an appearance of moderation toward those he hated. His detestation of the Christians had been for some time kept within bounds by the esteem he still felt for the French; but he had no sooner heard of the deference shown by their general to the orders he had sent him, than, beginning to fear nothing, he spared none.
