Napol%C3%A9on, Prince Imperial
Napolon, Prince Imperial was the only child of Emperor Napoleon III of France and his Empress consort Eugnie de Montijo. After his father was dethroned in 1870, he relocated with his family to England. On his fathers death in January 1873, he was proclaimed Napoleon IV, Emperor of the French by the Bonapartist faction.
In the R. F. Delderfield novel Long Summer Day , Boer War veteran Paul Craddock buys a farm in 1900 or 1901. The middleaged estate manager, Rudd, is somewhat embittered at having been one of the soldiers who had failed to rescue the Prince Imperial in 1879. Craddock is aware of the events, because by coincidence he had been born that very day.
