The record

On 11 April 1814, Napoleon signed the Treaty of Fontainebleau with representatives of Austria, Russia, and Prussia, ending his rule as emperor and sending him into exile on Elba.

Coincidence, not causation: the date is real and ephemeris-based, but a retrograde window is observed, never blamed. For entertainment, not navigation.
