Flight from Bordeaux, 1815

Louis-Antoine and Marie-Thérèse played together at Versailles so not sure why she would not remeber seeing him, unless it was amnesia brought on by trauma. From Shannon Selin:

Louis-Antoine, Duke of Angoulême, was born on August 6, 1775, the son of the Count of Artois and Marie Thérèse of Savoy. He is less well known than his cousin and wife, Marie-Thérèse, Duchess of Angoulême, who was born at Versailles on December 19, 1778. She was the eldest child of Louis XVI and Marie Antoinette, and the only one of their offspring to survive the French Revolution. Marie-Thérèse (or Madame Royale, as she was then known) was imprisoned in the Temple, the remains of a medieval fortress in Paris, from August 13, 1792 to December 18, 1795, the eve of her seventeenth birthday. During this time her parents were guillotined and her younger brother – imprisoned in a separate room and neglected – died of illness. On her release from prison, Marie-Thérèse was taken to Vienna (her mother was a member of the Austrian royal family). She then joined her uncle Louis XVIII in exile in Mitau, in present-day Latvia, where he was living as a guest of the Russian Tsar. Louis XVIII wanted Marie-Thérèse to marry the Duke of Angoulême. She readily agreed, as it was a project her parents had favoured, though she could not remember ever having seen her cousin. They were married on June 10, 1799 at Jelgava Palace. (Read more.)
