Norwegian campaign (1940) The Norwegian campaign was a military campaign in World War II fought in spring 1940 that resulted in the occupation of Norway by Nazi Germany and the withdrawal of Allied forces; it involved complex interactions among naval warfare, air warfare, land warfare, and strategic diplomacy. The campaign shaped the early wartime careers of figures such as Winston Churchill, Adolf Hitler, Erich Raeder, and Vidkun Quisling, influenced Battle of Britain preparations, and altered the balance of North Sea control between Kriegsmarine and the Royal Navy.
Background and strategic context
In late 1939 and early 1940, strategic concerns about supplies of Swedish iron ore, access to the Atlantic Ocean, and control of Baltic Sea exit routes prompted planning by Germany and debates in United Kingdom and France about intervention. German planners including Adolf Hitler and Erich Raeder feared blockade and sought secure seaways from Narvik and Luleå, while Allied strategists such as Winston Churchill and Maurice Gamelin debated mining operations in the North Sea and operations linked to Åndalsnes and Namsos. Norwegian neutrality under the King Haakon VII and government led by Johan Nygaardsvold complicated decisions involving Royal Navy deployment, French Navy participation, and political figures like Vidkun Quisling and the Nazi Party sympathizers.
German invasion (Operation Weserübung)
On 9 April 1940, Germany launched Operation Weserübung with coordinated landings and airborne operations targeting Oslo, Kristiansand, Bergen, Trondheim, and Narvik, combining transports, Kampfgruppe, and warships under commanders including Niklas von Falkenhorst and admirals of the Kriegsmarine. German forces seized Majorca?—sorry—seized Narvik and seized coastal shipping, while airborne forces and Gebirgsjäger advanced toward Oslofjord where engagements involved vessels of the Royal Norwegian Navy and municipal defenses influenced by Konrad Sund]. The coup-like appointment of Vidkun Quisling attempted to create a collaborationist administration, provoking resistance from King Haakon VII and the cabinet in Elverum.
Allied intervention and operations
The United Kingdom and France executed expeditionary operations aimed at cutting iron ore routes and supporting Norwegian forces, dispatching units to Narvik, Namsos, Åndalsnes, and Lofoten Islands with involvement from Royal Navy, Royal Air Force, French Foreign Legion units, and Polish forces escaping continental Europe. Allied commanders including Winston Churchill, Claude Auchinleck, and French naval officers coordinated landings, air support, and logistical routes through bases such as Scapa Flow and staging from Shetland and Orkney Islands, while political leaders debated intervention after the German invasion of Denmark and with awareness of Soviet Union neutrality. Allied amphibious and mountain warfare efforts intersected with Norwegian leadership under Otto Ruge and resistance elements that sought to defend ports and railways.
Campaign progression and key battles
Fighting centered on the northern port of Narvik, the central approaches to Trondheim, and the Oslofjord defenses, producing engagements such as the naval Battle of Narvik with destroyer and destroyer-escort actions, land battles at Dombås and Lillehammer-area skirmishes, and urban fighting near Bergen and Kristiansand. The campaign saw tactical victories and defeats: Allied forces temporarily recaptured Narvik in May during the Battle of Narvik with combined Royal Navy and French Navy support, while German air assaults and mountain troops overcame Norwegian positions at Bjørnvik and other passes, and the fall of Oslo after engagements at Fornebu led to political crisis and consolidation of German control.
Naval and air warfare
Naval actions included fleet engagements between the Kriegsmarine and the Royal Navy such as the battles around Narvik, sinking of the Bismarck—sorry—losses of German destroyers, and the use of pocket battleship sorties that exposed shortcomings in German surface strategy; carrier operations by HMS Furious and HMS Glorious and submarine patrols by U-boat flotillas shaped outcomes. Air operations involved Luftwaffe control of airfields seized at Fornebu and Sola, RAF sorties from Scapa Flow and Scotland against transport convoys, and the effective use of dive-bombers like the Junkers Ju 87 Stuka and fighters such as the Messerschmitt Bf 109, contributing to air superiority that facilitated German landings and interdicted Allied naval movements.
Occupation and evacuation
Following German consolidation and strategic decisions influenced by events on the Western Front, Allied commanders ordered evacuations from northern and central Norway in late May and early June, culminating in withdrawal from Narvik, Namsos, and Åndalsnes while remaining Norwegian forces either capitulated or withdrew into resistance. The evacuation operations involved complex naval maneuvers by the Royal Navy and troop movements to Scotland and France, and the occupation established German administrative control through Reichskommissariat structures, collaborationist elements like the movement led by Vidkun Quisling, and the placement of garrisons along fjords and rail junctions.
Aftermath and consequences
The campaign had strategic consequences: Germany secured seaborne access to Swedish iron ore routes and coastal bases, prompting reallocation of Royal Navy and RAF resources that affected preparations for the Battle of Britain and Mediterranean strategy; the campaign elevated political profiles of Winston Churchill and military lessons for both Kriegsmarine and Royal Navy about combined operations, convoy protection, and air-sea integration. Norwegian exile leadership, including King Haakon VII and the Norwegian government-in-exile in London, coordinated resistance and formed Free Norwegian forces that later fought in United Kingdom theaters, while wartime memory of events at Narvik, Fornebu, and the actions of figures like Vidkun Quisling influenced postwar legal and political reckoning in Norway and beyond.
