Bonjour Zastrow,
Last time I checked all my military history reference books, the Germans lost the naval battle but won their overall objective of holding and occupying Norway thus securing their iron ore supply.
The Germans had about 5000 troops at Narvik, where as the Allied forces of Norwegians, British, French, and Polish troops numbered around 25,000. The ad hoc German troops comprised of Gebirgsjägers, Sailors, and some Fallschirmjägers took some severe blows but held off the Allies.
But being part French myself....my mother is from Metz....I can see your point of view.
Vive la France! Bergheil und Horrido!
