Maybe a podcast Union of Salvation? While much after the Napoleonic era, some players were. Napoleonic movies brought this up.

Have watched the short version without knowing a word, started looking into the event on line, then long version still not understanding a word until finally watching short version and getting subtitles, just watched it again tje other week with subtitles.

I know the movie is very close to real events, even the ice bombardment and the Hanging fiasco and they while not shown hung them again. Many of the conspirators served in the Napoleonic wars and occupation of Paris.
