In 1815 Napoleon escaped from Elba, and returned to power in France. D'Arblay, who was serving with the King's Guard, remained loyal to King Louis XVIII and became involved in the military actions that followed. Burney fled to Belgium. When her husband was wounded she joined him at Trèves (Trier) and together they returned to Bath in England, to live at 23 Great Stanhope Street. Burney wrote an account of this experience and of her Paris years in her Waterloo Journal of 1818–1832. D'Arblay was promoted to lieutenant-general, but died shortly afterwards of cancer, in 1818.
