“First aim: advance to the Vistula and Narew. Our technical superiority will break the nerves of the Poles. Every newly-created Polish force shall again be broken at once. Constant war of attrition.
“New German frontier according to healthy principle. Possibly a protectorate as a buffer. Military operations shall not be influenced by these reflections. Complete destruction of Poland is the military aim. To be fast is the main thing. Pursuit until complete elimination.
“Conviction that the German Wehrmacht is up to the requirements. The start shall be ordered, probably by Saturday morning.” (1014-PS)
D. Expansion into General War of Aggression: Scandinavia, The Low Countries, The Balkans.
The aggressive war having been initiated in September 1939, and Poland having been defeated shortly after the initial assaults, the Nazi aggressors converted the war into a general war of aggression extending into Scandinavia, into the Low Countries, and into the Balkans. (Under the division of the case agreed by the four Chief Prosecutors, this phase of aggression was left for development to the British prosecuting staff, and is discussed in Sections 9, 10 and 11 of this Chapter, infra.)
E. Aggression Against the U. S. S. R.
The attack upon Russia was preceded with premeditation and deliberation. Just as, in the case of aggression against Czechoslovakia, the Nazis had a code name for the secret operation, “Case Green”, so in the case of aggression against the Soviet Union, they had a code name, “Case Barbarossa”. A secret directive, Number 21, issued from the Fuehrer’s Headquarters on 18 December 1940, relating to “Case Barbarossa,” was captured among the OKW files at Flensberg (446-PS). This directive was issued more than six months in advance of the attack. (Other evidence shows that the planning occurred even earlier.) This order, signed by Hitler and initialled by Jodl and Keitel, was issued in nine copies, of which we have the fourth. The directive reads:
“The German Armed Forces must be prepared to crush Soviet Russia in a quick campaign before the end of the war against England. (Case Barbarossa.)
“For this purpose the Army will have to employ all available units with the reservation that the occupied territories will have to be safeguarded against surprise attacks.
“For the Eastern campaign the Air force will have to free such strong forces for the support of the Army that a quick completion of the ground operations may be expected and that damage of the Eastern German territories will be avoided as much as possible. This concentration of the main effort in the East is limited by the following reservation: That the entire battle and armament area dominated by us must remain sufficiently protected against enemy air attacks and that the attacks on England and especially the supply for them must not be permitted to break down.
