GENERAL MILITARY World War II
The Norwegian campaign (8 April – 10 June 1940) involved the attempt by Allied forces to defend northern Norway coupled with the Norwegian military’s resistance to the country’s invasion by Nazi Germany in World War II.
Planned as Operation Wilfred and Plan R 4, while the German attack was feared but had not yet happened, the battlecruiser HMS Renown set out from Scapa Flow for Vestfjorden with twelve destroyers on 4 April. The Royal Navy and the Kriegsmarine met at the first and second naval battles of Narvik on 10 and 13 April, and British forces conducted the Åndalsnes landings on 13 April. The main strategic reason for Germany to invade Norway was to seize the port of Narvik and guarantee the delivery of iron ore needed for German steel production.[2]
The campaign was fought until 10 June 1940 and saw the escape of King Haakon VII and Crown Prince Olav to the United Kingdom. A British, French and Polish expeditionary force of 38,000 troops landed in the north. It had moderate success but made a rapid strategic retreat after the Battle of France began on 14 May. The Norwegian government then went into exile in London. The campaign ended with the occupation of the entirety of Norway by Germany but elements of the Norwegian military escaped and fought on overseas.
