Maréchal Chaudron "(de son vrai nom Jean Berthaut, sergent de grenadiers)".

I find no mention of his name in any book on Google books prior to the 1891 publication of Marbot's Mémoires.

French text:

Mémoires du général Bon de Marbot, Volume 2, pp 418ff:

Oman: "The story of the marauding sergeant ' Marechal Chaudron ' and his band, given by Marbot (ii. pp. 418-19), is probably exaggerated by that lively narrator — the scale is too large."
