When the final orders for the German invasion of
Norway were given, the diary of the Naval Operations Staff for 23
March 1940 records: "A mass encroachment by the English into
Norwegian territorial waters . . . . is not to be expected at the
present time."
And Admiral Assmann's entry for 26 March says: "British
landing in Norway not considered serious."
Documents which were subsequently captured by the Germans are
relied on to show that the Allied plan to occupy harbors and airports
in Western Norway was a definite plan, although in all points
considerably behind the German plans under which the invasion was
actually carried out. These documents indicate that an altered plan
had been finally agreed upon on 20 March 1940, that a convoy should
leave England on 5 April, and that mining in Norwegian waters would
begin the same day; and that on 5 April the sailing time had been
postponed until 8 April. But these plans were not the cause of the
German invasion of Norway. Norway was occupied by Germany to afford
her bases from which a more effective attack on England and France
might be made, pursuant to plans prepared long in advance of the
Allied plans which are now relied on to support the argument of
self-defense.
It was further argued that Germany alone could decide, in
accordance with the reservations made by many of the Signatory Powers
at the time of the conclusion of the Kellogg-Briand Pact, whether
preventive action was a necessity, and that in making her decision
her judgment was conclusive. But whether action taken under the claim
of self-defense was in fact aggressive or defensive must ultimately
be subject to investigation and adjudication if international law is
ever to be enforced.
No suggestion is made by the defendants that there was any plan
by any belligerent, other than Germany, to occupy Denmark. No excuse
for that aggression has ever been offered.
As the German Armies entered Norway and Denmark, German memoranda
were handed to the Norwegian and Danish Governments which gave the
assurance that the German troops did not come as enemies, that they
did not intend to make use of the points occupied by German troops as
bases for operations against England, as long as they were not forced
to do so by measures taken by England and France, and that they had
come to protect the North against the proposed occupation of
Norwegian strong points by English-French forces.
The memoranda added that Germany had no intention of infringing
upon the territorial integrity and political independence of the
Kingdom of Norway then or in the future. Nevertheless, on 3 June
1940, a German naval memorandum discussed the use to be made of
Norway and Denmark, and put forward one solution for con-
