In the third novel, "The Vicomte de Bragelonne", Athos takes a major behind-the-scenes part in historical events, first helping with the restoration of Charles II to the throne of England, and then being entrusted with the diplomatic task of arranging the wedding of Henrietta of England and Philippe I, Duke of Orléans. Athos eventually falls out with King Louis XIV of France, who has seduced his son Raoul's fiancée, and is briefly thrown into the Bastille for voicing his contempt. After being pardoned at d'Artagnan's instigation, Athos withdraws to his home, where he dies of sorrow after Raoul is killed at war.
