Dear Bas,
Since a lot of years, I am working on the history of the "5th corps d'infanterie de la Grande Armée" (Gl Lauriston) in 1813. Division Puthod (in which one of my ancestors served in the artillery train) was a division of that corps untill her destruction in august. Most of Puthod's soldiers were coming from belgian departements.
