Port of Narvik

Extracted from the Wikipedia article Narvik (town).
World War II
The port of Narvik proved to be strategically valuable in the early years of World War II and the town became a focal point of the Norwegian Campaign. In 1939, Germany's war industry depended upon iron ore mined in Kiruna and Malmberget in Sweden. During the summer season, this ore could be sent by cargo ship to Germany through the Baltic Sea via the Swedish port of Luleå on the Gulf of Bothnia. However, when the Gulf of Bothnia froze during the winter, more shipments of the ore needed to be transported through Narvik and, from there, down the west coast of Norway to Germany. The town of Narvik is linked by rail to Sweden, but not to any other towns in Norway. As a result, Narvik serves as a gateway to the ore fields of Sweden that cannot be easily reached from southern Norway via land. Winston Churchill realised that the control of Narvik meant stopping most German imports of iron ore during the winter of 1940. This would be advantageous to the Allies and it might help shorten the war. Equally as important, later in the war, German submarines and warships based there threatened the allied supply line to the Soviet Union.
