Allied intervention in Norway

Allied intervention in Norway. This military campaign, codenamed Operation Wilfred and Plan R 4, was a direct response to the German invasion of Norway on 9 April 1940. The Allies, primarily the United Kingdom and France, aimed to support Norway and deny Nazi Germany access to strategic Swedish iron ore shipped via the port of Narvik. Despite fierce fighting, the campaign culminated in a full Allied withdrawal by early June, leaving Norway under German occupation.

Background and causes

The strategic catalyst for the intervention was the vital flow of Swedish iron ore from Gällivare to Germany, which traveled via the Norwegian railway to the ice-free port of Narvik. Winston Churchill, then First Lord of the Admiralty, was a principal advocate for mining Norwegian territorial waters to disrupt this route, an operation approved as Operation Wilfred. Concurrently, the British War Cabinet developed Plan R 4, a contingency to land troops at Narvik, Trondheim, Bergen, and Stavanger if Germany reacted. The immediate trigger was the preemptive German invasion of Norway, which commenced on 9 April 1940 with simultaneous assaults on Oslo, Kristiansand, Stavanger, Bergen, Trondheim, and Narvik during Operation Weserübung.

Initial landings and operations

Allied forces, hastily assembled, began their primary landings in mid-April. The central thrust was a two-pronged assault on Trondheim, codenamed Operation Maurice and Operation Sickle, which involved landings at Namsos and Åndalsnes to encircle the city. Troops included the British 146th Infantry Brigade, French Alpine troops, and the British 148th Infantry Brigade. Simultaneously, a separate naval task force aimed at Narvik, where German forces under Eduard Dietl were isolated. Initial landings at Harstad established a base for operations against Narvik, involving Polish Independent Highland Brigade and French Foreign Legion units. Poor coordination, Luftwaffe air superiority, and difficult terrain hampered all advances outside the Narvik area.

Naval engagements

The naval theater witnessed several critical battles that shaped the campaign. Early actions included the First Battle of Narvik and the Second Battle of Narvik, where the Royal Navy destroyed several Kriegsmarine destroyers. The Battle of the Atlantic context was evident as the German battleships Scharnhorst and Gneisenau sank the British aircraft carrier HMS Glorious during the evacuation phase. Other significant clashes included the Battle of the Drøbak Sound, where Norwegian coastal defenses sank the German heavy cruiser Blücher, and actions off Bergen and Stavanger. These engagements inflicted heavy losses on the Kriegsmarine, but Allied naval power could not overcome German control of the skies.

Withdrawal and evacuation

The deteriorating situation in France following the Battle of France forced the Allied Supreme War Council to prioritize the French front. The decision for a full evacuation from central Norway was made in early May. Forces at Namsos and Åndalsnes were withdrawn in operations codenamed Operation Alphabet, completed by 3 May. The Narvik sector saw a final Allied offensive that recaptured the town on 28 May, involving Norwegian 6th Division and French Alpine troops. However, this victory was immediately followed by evacuation orders; all Allied forces were pulled out from Narvik and Harstad by 8 June, covered by the Royal Navy and the French Navy.

Aftermath and consequences

The failed intervention led to the complete Occupation of Norway by Nazi Germany, with Vidkun Quisling heading a collaborationist government. The campaign proved a strategic defeat for the Allies but had significant long-term consequences. It exposed critical weaknesses in Allied inter-service cooperation and highlighted the decisive role of air power. Politically, it contributed to the fall of Neville Chamberlain and the ascent of Winston Churchill as Prime Minister of the United Kingdom. Norway's exile government, under King Haakon VII, continued the fight from London, while Norwegian merchant marine ships proved invaluable to the Allied cause. The campaign also secured Germany's northern flank and access to Swedish resources for the remainder of the war.
