Ofotfjord, Norway, 23 July 2015 2. Looking east along Ofotfjord towards Narvik in the far distance. Narvik's main business is shipping high quality iron ore from Sweden. On 9 April 1940 the Germans invaded neutral Norway to secure the iron ore for themselves. The naval battle of Narvik then followed, in which the Royal Navy defeated the Kriegsmarine, inflicting heavy losses. British and French troops were landed, but were forced to withdraw after Germany invaded France on 10 May. The Norwegians repelled the Germans in the Narvik area, but were over-run after the Anglo-French withdrawal. Five years of occupation followed until the general German capitulation in western Europe on 8 May 1945 (VE Day).
