The record
On June 4, 1745, Frederick the Great's Prussian army decisively defeated the Austro-Saxon forces of Prince Charles Alexander of Lorraine at the Battle of Hohenfriedberg.
Coincidence, not causation: the date is real and ephemeris-based, but a retrograde window is observed, never blamed. For entertainment, not navigation.
