So this isn't a Napoleon wins the 100 days WI, but what I find to be a more interesting one. Say Napoleon delivers crushing defeats to both Wellington and Blucher, before being overpowered by the late arriving Austrians and Russians? What effect would this have on the post-Napoleon world and the Congress of Vienna? Napoleon is still gone and France probably still sees the monarchy restored, but what about the rest of Europe, specifically the German states and the future for unification?
