Desfarges led two battalions (636 soldiers)[1] on board five warships, in the second French embassy to Siam.
The embassy to King Narai, under the special envoys Simon de la Loubère and Claude Céberet du Boullay, left France for Siam in March 1687.
[1] The disembarkment of Desfarges troops in Bangkok and the troops of his officer du Bruant in Mergui led to strong nationalistic movements in Siam directed by Phra Petratcha and ultimately resulted in the 1688 Siamese revolution in which King Narai died, Constantine Phaulkon was executed, and Phra Petratcha became king.
[5] In the latter part of 1689, Desfarges captured the island of Phuket in an attempt to restore French control.
Desfarges left in March 1690, but died of illness on his way back to France on board the Oriflamme.
