“Avance Avance! Toujours avance!”... Frederick the Great per Patton in “Patton”
Unfortunately the quote doesn't belong to Fred the Great though it is often attributed to him. Even the original is misquoted in the movie.
The original quote belongs to Georges-Jacques Danton
"Il nous faut de l'audace, et encore de l'audace, et toujours de l'audace"
"We must dare, and again dare, and forever dare."
Garde la Foi, mes amis! Nous nous sommes les sauveurs de la République! Maintenant et Toujours!
(Keep the Faith, my friends! We are the saviors of the Republic! Now and Forever!)
