|Francois III d'Aubusson, Count de La Feuillade|
Later the Duke & Marechal de France
In 1668 French King Louis XIV agreed to send a volunteer Corps to support a garrison of Candia besieged by Turks. It was numbered 600 men, all of them were volunteers. The command was given to Francois d'Aubusson Duke de La Feuillade (see Wiki on him, link). The Corps was divided into 4 Brigades (in fact - companies) of 100 men each under command of Count St.Paul, Duke de Caderousse, Count de Ville-maur & Duke de Chateau Thierry. The rest 200 (mostly nobles) were under La Feuillade.
A Frenchmen, who participated in the La Feuillade expedition, wrote that only 230 men out of 600 left Candia, the rest were killed or died from sickness. This man also wrote that Candia's garrison in autumn of 1668 totalled about 7.000, & composed of numerous companies (see about de Ville's army sent to Candia in 1665, link), but the most of them were below 25 men.
