French infantry, Ligne (line) and Legere (lights), in the pre-Bardin-reforms uniform and wearing shako. It's likely that this uniform would have been worn by many if not most French ligne regiments in Russia in 1812, and well into 1813 by some regiments as well.
The models are depicted in the appearance most likely for large battles -- other than the officers, they are still wearing their loose campaigning trousers, but have removed their overcoats and shako covers, although they have not gone as far as to attach their shako cords. It seems that breeches, gaiters and shako cords would have been visible only on parade and other ceremonial duties. Sculpted by Mike Broadbent, painted by Rafa Archiduque or Steve Dean.
