The record
On 7 July 1770, the Battle of Chesma concluded in the waters between Anatolia and Chios, marking the first of several disastrous fleet defeats for the Ottoman Empire against Russia.
Coincidence, not causation: the date is real and ephemeris-based, but a retrograde window is observed, never blamed. For entertainment, not navigation.
