Crisis Management (Norwegian version) We can not say that the Germans everything went smoothly. For example, the German submarines deployed in the coast of Norway, had to torpedo armed with magnetic fuzes, that did not work. Because of this, Nazi U-boat could not sink a few large British military ships. If not for this fact, the British defeat would be even more difficult in terms of impact on the psyche. Grouping Dietl and German destroyers in Narvik immediately put in a difficult position. Before they could take the city were left without a supply: the enemy caught three supply ship to move into care Dietl. German destroyers, having spent a lot of fuel and ammunition, could not replenish their stocks. Mountain Dietl arrows never got guns. At the beginning of the fifth hour in the morning on April 10 the Germans attacked the British 2nd Destroyer Flotilla - five pennants, rushed to the fjords of the city. Having lost two ships, the British sank two German destroyers and damaged five others. But this was only the beginning of the crisis.
