“3) I therefore issue the following orders for the further conduct of military operations:
“(a) Preparations should be made for offensive action on the northern flank of the Western Front crossing the area of Luxembourg, Belgium, and Holland. This attack must be carried out as soon and as forcefully as possible.
“(b) The object of this attack is to defeat as many strong sections of the French fighting army as possible, and her ally and partner in the fighting, and at the same time to acquire as great an area of Holland, Belgium, and northern France as possible, to use as a base offering good prospects for waging aerial and sea warfare against England and to provide ample coverage for the vital district of the Ruhr.”
Nothing could state more clearly or more definitely the object behind the invasion of these three countries than that document expresses it.
On the 15th of October 1939 the Defendant Keitel wrote a most-secret letter concerning “Fall Gelb” which was the name given to the operation against the Low Countries. In it he said that:
“The protection of the Ruhr area by moving aircraft reporting service and the air defense as far forward as possible in the area of Holland is significant for the whole conduct of the war. The more Dutch territory we occupy, the more effective can the defense of the Ruhr area be made. This point of view must determine the choice of objectives of the Army, even if the Army and Navy are not directly interested in such territorial gain. It must be the object of the Army’s preparations, therefore, to occupy, on receipt of a special order, the territory of Holland, in the first instance in the area of the Grebbe-Maas line. It will depend on the military and political attitude of the Dutch, as well as on the effectiveness of their flooding, whether objectives can and must be further extended.”
The Fall Gelb operation had apparently been planned to take place at the beginning of November 1939. We have in our possession a series of 17 letters, dated from 7th November until the 9th May postponing almost from day to day the D-Day of the operation, so that by the beginning of November all the major plans and preparations had in fact been made.
On the 10th of January 1940 a German airplane force-landed in Belgium. In it was found the remains of an operation order which the pilot had attempted to burn; setting out considerable details of the Belgian landing grounds that were to be captured by the Air Force. Many other documents have been found which illustrate the planning and preparation for this invasion in the latter half of 1939 and early 1940, but they carry the matter no further, and they show no more clearly than the evidence to which I have already referred, the plans and intention of the German Government and its Armed Forces.
