 As in the play, Bergerac did fight at the a battle of the Thirty Years' War between French and Spanish forces in France (though this was not the more famous final Battle of Arras, fought fourteen years later).One of his confrères in the battle was the Baron Christian of Neuvillette, who married Cyrano's cousin.However, the plotline of Rostand's play, "Cyrano de Bergerac", involving Roxane and Christian is entirely fictional.
