Royal Norwegian Navy conflict World War II
Norway was neutral during World War I, but the armed forces were mobilised to protect Norway's neutrality. The neutrality was sorely tested – the nation's merchant fleet suffered heavy casualties to German U-boats and commerce raiders.
World War II began for the Royal Norwegian Navy on April 8, 1940, when the German torpedo boat Albatross attacked the guard ship Pol III. In the opening hours of the Battle of Narvik, the old coastal defence ships ("panserskip") HNoMS Eidsvold and HNoMS Norge, both built before 1905 and hopelessly obsolete, attempted to put up a fight against the invading German warships; both were torpedoed and sunk. The German invasion fleet heading for Oslo was significantly delayed when Oscarsborg Fortress opened fire with two of its three old 28 cm guns, followed by the 15 cm guns on Kopås on the eastern side of the Drøbak strait. The artillery pieces inflicted heavy damage on the German heavy cruiser Blücher, which was subsequently sunk by torpedoes fired from Oscarsborg's land-based torpedo battery. Blücher sank with over 1,000 casualties among its crew and soldiers aboard. The German invasion fleet – believing Blücher had struck a mine – retreated south and called for air strikes on the fortress. This delay allowed King Haakon VII of Norway and the Royal family, as well as the government, to escape capture.
