Tactical German losses could reshape the Narvik campaign

The counterfactual broadens from the harbour action to the campaign that followed. German destroyers damaged or lost against Nidaros would be less able to resist the first British destroyer attack. A weakened German flotilla could encourage the later force built around Warspite and Tribal-class destroyers to arrive with more troops and a stronger landing plan. Longer and louder fighting would also alert Norwegian reservists before the German landing force consolidated ashore. That pressure could reduce the ability of a sympathetic or ineffective local commander to suppress resistance. Gorgon's enormous bulges might further complicate the result by absorbing or deflecting torpedo explosions before they reached the main hull. None of these effects is certain, but together they show how added warning time and enemy attrition can propagate from a tactical encounter into an operational campaign.
