Rare love letters to French aristocrat shed light on Louis XVI maritime mystery

As he prepared to climb the scaffolding to be publicly executed by guillotine on 21 January 1793, Louis XVI is reported to have asked: “Is there news of Monsieur de la Pérouse?”

He was referring to Jean-François de Galaup, the count of Pérouse, a naval officer and navigator whom the French king had dispatched in 1785 on a round-the-world scientific mission to rival discoveries made by the English explorer Captain James Cook.
