Badinguet Allant a la Guerre – Badinguet Revenant
Badinguet Going to War Badinguet Returning
Napoleon III was nicknamed Badinguet after the workman he is said to have impersonated when he escaped from the Fortress of Ham in 1846. He had been condemned to perpetual imprisonment there for his unsuccessful invasion of France at Boulogne six years earlier. Needless to say, the name Badinguet was intended to humiliate the Emperor-President.
