Scenario:
As per OTL, Napoleon defeat German states.
Some patriotic Austrian/Prussian Military officers "deserted" and formed an insurgent, to avoid their country been held responsible by their operation.
As per OTL, Napoleon invade Russia.
The insurgents goes on to sabotage supply lines and conduct other guerrilla operations.
Empress Marie-Louise with the new-born Napoleon II were on a tour in Confederation of the Rhine.
The insurgents intercept them, captured both.
Held Marie in captivity, hack Napoleon II into pieces and send it to Napoleon.
Force Napoleon to personally return from Russian front, hopefully collapsing the French army earlier than OTL.
Don't take it too seriously, just a scenario jumped into my head.
