The record

On 7 September 1812, Napoleon’s Grande Armée fought the Imperial Russian Army on the outskirts of Moscow near the village of Borodino during the French invasion of Russia.

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