These foreigners transferred to the Kingdom of Siam, were regarded as its defenders. Twenty-four of them were selected to act as a bodyguard to the prime minister, and the King himself never appeared in public without a French escort. One of these men was raised to the rank of colonel of the guards and others were placed in command of Siamese regiments in order to instruct them in military discipline. The soldier who fell ill was sent to Louvo where he received better attention than he would have in his own home. These privileges were extended to all Christians who enjoyed full rights of citizenship. The French Jesuits were allowed to preach the Gospel in all parts of the Kingdom. The King appointed many of them to Buddhist temples under the pretext of their having to learn Siamese, but in reality to observe their procedure as the priests were neither suited for, nor willing to act as spies. The minister laid the foundations of a college for the education of the younger member of the nobility under the name of College of Constantine. M. the Chevalier de Chaumont having brought the negociations to a conclusion departed from Siam at the end of 1688. He was accompanied by three Siamese Ambassadors equally distinguished by birth and ability and who were in charge of some rich gifts for the King of France. The object of this mission was to demand that engineers should be sent to instruct the Siamese in the art of fortification and in the methods of attack and defence of positions. They were also empowered to request a body of troops to perfect the Siamese in military evolutions. The French officers and soldiers who remained in Siam abused the consideration they had enjoyed. Convinced of their superiority in power and knowledge, they were rash enough to presume upon it, and instead of laying themselves out to please, desired to be thought much of. With impudent mockery they condemned every thing that differed from their own customs. The people and nobles at first suffered the pride of their insolent guests in silence. The Bishops and clergy alone were not exposed to the popular dislike. Keeping within the seminary and devoting their time to labour, they were neither vain nor ambitious, they were known by the services they rendered to the public and above all to the unfortunate. The Jesuits, animated without doubt by the same motives had other means to attain their end; and it was by the brilliancy of their accomplishments that they endeavoured to enjoy the public confidence. Surgeons, physicians, astronomers and mathematicians, they beheld men of all stations in life coming to ask their advice and to follow their teaching.
