Could holding Narvik have divided wartime Norway?

Would better Allied planning and an immediate landing at Narvik have saved Norway?

Not necessarily the whole country, but it might have secured central and northern Norway and produced a difficult divided-country stalemate for Germany.

An immediate Allied landing after the naval action at Narvik would not guarantee the survival of all Norway. It could, however, have secured a defensible position and changed later strategic choices. The country's mountainous terrain might support a stalemate, with central and northern Norway held by Norwegian forces with British support and the south under German control. Such a division would complicate German occupation and favour resistance or guerrilla warfare. The comparison with Finland's use of lake country against Russian forces shows how geography can magnify a defender's strength.
