Hello Chris.
In the 1980's the French Government made an agreement with Vietnam to recover all those remains of fallen members of French military incl. Indochinese personnel which could be recovered for reburial at a French national site. The site was established at Frejus within sight of the Mediterranean Sea over which French origin military personnel traveled to reach Indochina.
The remains so gathered were reburied at Frejus and the total number of remains are listed as 26,000 plus. A large number have their individual graves. Again very unfortunately the registry contains a numerous errors, distortions etc which should have been easily avoided and in my view puts a very commendable enterprise into a shaky light. An example is my former company sgt.major ( adjudant de compagnie ) Marechal des Logis-Chef Manuel Bonastre listed with several errors in his single entry ( regt., rank, dod).
