I have never seen this special set before, but my educated guess aligns closely with the historical details. While the Chasseurs à Cheval of the Imperial Guard are typically represented with green and red, variations such as
yellow facings and plumes are indeed documented in
parade dress, especially for ceremonial roles during the height of the Empire (e.g., the
Coronation of Napoleon,
grand reviews, and
Tuileries parades).
The combination of:
- Green tunics
- Yellow cuffs and collars
- Yellow plumes on black fur shakos
- Sabres drawn in a charging stance
…strongly supports the identification.
My only explanation? This regiment must have been
moved straight from the parade ground onto the battlefield. After all,
Napoleon was a brilliant — and occasionally theatrical — tactician. Wouldn't be the first time he turned a fashion statement into a flanking maneuver!
