“The task of the Group XXI: Capture by surprise of the most important places on the coast by sea and airborne operations.
“The Navy will take over the preparation and carrying out of the transport by sea of the landing troops. * * * The Air Force, after the occupation has been completed, will ensure air defense and will make use of Norwegian bases for air warfare against Britain.” (C-174)
Whilst these preparations were being made, and just prior to the final decision of Hitler, reports were coming in through Rosenberg’s organization from Quisling. The third paragraph in Annex I, the section dealing with Norway, has this information:
“Quisling’s reports, transmitted to his representative in Germany, Hagelin, and dealing with the possibility of intervention by the Western Powers in Norway with tacit consent of the Norwegian Government, became more urgent by January. These increasingly better substantiated communications were in sharpest contrast to the views of the German Legation in Oslo, which relied on the desire for neutrality of the then Norwegian Nygardszvold Cabinet, and was convinced of that government’s intention and readiness to defend Norway’s neutrality. No one in Norway knew that Quisling’s representative for Germany maintained closest relations to him; he therefore succeeded in gaining a foothold within governmental circles of the Nygardszvold cabinet and in listening to the cabinet members’ views. Hagelin transmitted what he had heard to the Bureau [Rosenberg’s bureau], which conveyed the news to the Fuehrer through Reichsleiter Rosenberg. During the night of the 16th to 17th of February, English destroyers attacked the German steamer ‘Altmark’ in Jessingjord.* * *” (007-PS)
(That is a reference to the action by the British destroyer Cossack against the German naval auxiliary vessel Altmark, which was carrying three hundred British prisoners, captured on the high seas, to Germany through Norwegian territorial waters. The position of the British delegation with regard to that episode is that the use that was being made by the Altmark of Norwegian territorial waters was in fact a flagrant abuse in itself of Norwegian neutrality, and that the action taken by H.M.S. Cossack, which was restricted to rescuing the three hundred British prisoners on board, no attempt being made to destroy the Altmark or to capture the armed guards on board her, was fully justified under international law.)
The Rosenberg report continues:
“The Norwegian Government’s reaction to this question permitted the conclusion that certain agreements had been covertly arrived at between the Norwegian Government and the Allies. Such assumption was confirmed by reports of Section Scheidt, who in turn derived his information from Hagelin and Quisling. But even after this incident the German Legation in Oslo championed the opposite view, and went on record as believing in the good intentions of the Norwegians.” (007-PS)
And so the Nazi Government preferred the reports of the traitor Quisling to the considered judgment of German diplomatic representatives in Norway. The result of the receipt of reports of that kind was the Hitler decision to invade Norway and Denmark. The culminating details in the preparations for the invasion are again found in Jodl’s diary. The entry for 3 March relates:
“The Fuehrer expressed himself very sharply on the necessity of a swift entry into N [Norway] with strong forces.
“No delay by any branch of the armed forces. Very rapid acceleration of the attack necessary.” (1809-PS)
