The record
Signed on 17 October 1797 by Napoleon Bonaparte and Count Philipp von Cobenzl, the Treaty of Campo Formio ended the War of the First Coalition and left Great Britain fighting revolutionary France alone.
Coincidence, not causation: the date is real and ephemeris-based, but a retrograde window is observed, never blamed. For entertainment, not navigation.
