Cyrano de Bergerac
The White Plume
On the battlefield, the white plume is a mark of military rank, a target for enemy guns. The fact that de Guiche threw his away in the heat of battle means he’s a huge ninny, as if we didn’t know that already. The fact that Cyrano picks it up is symbolic of his staunch courage, loyalty to his country and fellow soldiers, and undying honor. It’s no surprise, then, that his last words are of this very plume, which is unstained, noble, honorable, etc.
