Good day,
I was working through this article:
https://www.napoleon-series.org/military-info/organization/c_lightinf.html
and compared to the line regiments most of the light look pretty strange, often twice formed from another light unit demi-brigade or from a pool of many pother units, none(except one) having battle honors from the Revolutionary Wars but only in the period of 1805 to 1809, etc..
All these information's just made me curious to dig deeper and so I'm searching for standard works that cover the creation & evolution of the light French infantry up to 1815.
With regards

Are you familiar with the regimental histories by Frederic Bejaud and Didier Davin? They might be of help:
