The great port of Le Havre stands at the mouth of the Seine estuary, which opens into the bay of,the Seine on the east.
The Seine descends from the Langres plateau, flows northwest down to Mry, turns to the west, resumes its north-westerly direction at Montereau, passes through Paris and Rouen and discharges itself into the Channel between Le Havre and Honfleur.
The RAF also dropped dummy parachutists and firework devices in a dummy airborne landing at Yvetot, some 30 miles North of Le Havre.
On 23 October 1992, they stowed away on MC Ruby, a cargo ship bound for Le Havre.
