Why the British intervention in Norway failed

Did Britain intervene in Norway after the fighting at Narvik?

Yes, but the campaign was conducted half-heartedly and hampered by a poor command structure.

The response distinguishes the fact of intervention from its execution. Britain did send forces, yet divided or unsuitable command arrangements and limited commitment undermined the effort. It points readers toward command structure as a central explanation rather than assuming that mere presence amounted to a coherent strategy.
