The record

On 2 May 1813 Napoleon Bonaparte secured a costly tactical victory over Prussian and Russian forces near Lützen, Saxony, during the War of the Sixth Coalition.

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