The record

On 14 February 1797, Admiral Sir John Jervis defeated a larger Spanish fleet under Lieutenant-general José de Córdoba y Ramos off Cape St. Vincent, securing Britain's access to the Mediterranean.

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