The case for concentrating at Namsos and Trondheim

British reinforcements were still landing while French and Norwegian forces pressed the Germans around Narvik. Fleischer's fury at the earlier surrender there helped drive the Norwegian aggression. The wider campaign was a force-allocation problem: the Allies tried to act everywhere while Germany was still vulnerable. The proposed alternative is to secure Namsos, block German movement, help Norwegian forces withdraw or link up, and close on Trondheim while Fleischer handled Narvik. Mountain positions required concentrated attacks instead of scattered commitments. As King Haakon and the government moved from Molde to Tromsø, German forces finally linked their southern advance with Trondheim after twenty days. Norwegian resistance had created a usable operational window, but the Allies failed to concentrate their strength before it closed.
