Heh, yeah, everyone who ever listened to Vissini knows you never get involved in a land war in Asia.
When I was a lieutenant, I read a biography of Napoleon. It quoted him as saying "l'audace, l'audace, toujours l'audace" to one of his field generals, maybe his brother-in-law. But these days, a quick search of the interwebz reveals that a lawyer and revolutionary named Georges Jacques Danton said something very similar during the French Revolution: "L'audace, et encore l'audace, et toujours l'audace," (Audacity, and again audacity, and always audacity).
And the revolution came BEFORE Napoleon's rise to power. In fact, kind of precipitated it.
So seems one of two things happened here: the biography I read was incorrect (but it was a scholarly work, so I kinda doubt that), or Napoleon borrowed it from Danton.* So that Patton could borrow it from him a century and a half later. Heh.
* they quite possibly knew one another.
