"The analogy, though nautical, is apt," said Rossignol. "During the reign of Louis XIII—whom it was my father’s great honor to serve as Royal cryptanalyst—Oyonnax had allowed the King’s armies to use his land as a base for invading the Franche-Comté, which they did frequently. In exchange for which he had been elevated to a Count. Such was his rank when he married the young Anne-Marie de Crépy. A few years after, he performed a like service for the legions of Louis XIV, which, since it led to the annexation of the whole of the Franche-Comté to France, caused the King to elevate him to a Duke. He and the new Duchess moved to Versailles, where he got to enjoy his new status for only a few months before she poisoned him."
