The Nazi conspirators next entered upon the specific planning for the acquisition of Austria and Czechoslovakia, realizing it would be necessary, for military reasons, first to seize Austria before assaulting Czechoslovakia. On 21 May 1935 in a speech to the Reichstag, Hitler stated that:
“Germany neither intends, nor wishes to interfere in the internal affairs of Austria, to annex Austria or to conclude an Anschluss.”
On 1 May 1936, within 2 months after the re-occupation of the Rhineland, Hitler stated:
“The lie goes forth again that Germany tomorrow or the day after will fall upon Austria or Czechoslovakia.”
Thereafter, the Nazi conspirators caused a treaty to be entered into between Austria and Germany on 11 July 1936, Article I of which stated that:
“The German Government recognizes the full sovereignty of the Federated State of Austria in the spirit of the pronouncements of the German Führer and Chancellor of 21 May 1935.”
Meanwhile, plans for aggression in violation of that treaty were being made. By the autumn of 1937 all noteworthy opposition within the Reich had been crushed. Military preparation for the Austrian action was virtually concluded. An influential group of the Nazi conspirators met with Hitler on 5 November 1937, to review the situation. It was reaffirmed that Nazi Germany must have “Lebensraum” in Central Europe. It was recognized that such conquest would probably meet resistance which would have to be crushed by force and that their decision might lead to a general war, but this prospect was discounted as a risk worth taking. There emerged from this meeting three possible plans for the conquest of Austria and Czechoslovakia. Which of the three was to be used was to depend upon the developments in the political and military situation in Europe. It was contemplated during this meeting that the conquest of Austria and Czechoslovakia would, through compulsory emigration of 2 million persons from Czechoslovakia and 1 million persons from Austria, provide additional food to the Reich for 5 million to 6 million people, strengthen it militarily by providing shorter and better frontiers, and make possible the constituting of new armies up to about twelve divisions. Thus, the aim of the plan against Austria and Czechoslovakia was conceived of not as an end in itself but as a preparatory measure toward the next aggressive steps in the Nazi conspiracy.
(b) The execution of the plan to invade Austria: November 1937 to March 1938.
Hitler, on 8 February 1938, called Chancellor Schuschnigg to a conference at Berchtesgaden. At the meeting of 12 February 1938, under threat of invasion, Schuschnigg yielded a promise of amnesty to imprisoned Nazis and appointment of Nazis to ministerial posts—meaning in Austria. He agreed to remain silent until Hitler’s next speech in which Austria’s independence was to be re-affirmed, but Hitler in that speech, instead of affirming Austrian independence, declared himself protector of all Germans. Meanwhile, subversive activities of Nazis in Austria increased. Schuschnigg, on 9 March 1938, announced a plebiscite for the following Sunday on the question of Austrian independence. On 11 March Hitler sent an ultimatum, demanding that the plebiscite be called off or that Germany would invade Austria. Later the same day a second ultimatum threatened invasion unless Schuschnigg should resign in 3 hours. Schuschnigg resigned. The Defendant Seyss-Inquart, who was appointed Chancellor, immediately invited Hitler to send German troops into Austria to “preserve order.” The invasion began on 12 March 1938. On 13 March Hitler by proclamation assumed office as Chief of State of Austria and took command of its armed forces. By a law of the same date Austria was annexed to Germany.
(c) The execution of the plan to invade Czechoslovakia: April 1938 to March 1939.
(1) Simultaneously with their annexation of Austria, the Nazi conspirators gave false assurances to the Czechoslovak Government that they would not attack that country. But within a month they met to plan specific ways and means of attacking Czechoslovakia, and to revise, in the light of the acquisition of Austria, the previous plans for aggression against Czechoslovakia.
(2) On 21 April 1938 the Nazi conspirators met and prepared to launch an attack on Czechoslovakia not later than 1 October 1938. They planned to create an “incident” to “justify” the attack. They decided to launch a military attack only after a period of diplomatic squabbling which, growing more serious, would lead to an excuse for war, or, in the alternative, to unleash a lightning attack as a result of an “incident” of their own creation. Consideration was given to assassinating the German Ambassador at Prague to create the requisite incident. From and after 21 April 1938, the Nazi conspirators caused to be prepared detailed and precise military plans designed to carry out such an attack at any opportune moment and calculated to overthrow all Czech resistance within 4 days, thus presenting the world with a fait accompli, and so forestalling outside resistance. Throughout the months of May, June, July, August, and September, these plans were made more specific and detailed, and by 3 September 1938 it was decided that all troops were to be ready for action on 28 September 1938.
(3) Throughout this same period, the Nazi conspirators were agitating the minorities question in Czechoslovakia, and particularly in the Sudetenland, leading to a diplomatic crisis in August and September 1938. After the Nazi conspirators threatened war, the United Kingdom and France concluded a pact with Germany and Italy at Munich on 29 September 1938, involving the cession of the Sudetenland by Czechoslovakia to Germany. Czechoslovakia was required to acquiesce. On 1 October 1938 German troops occupied the Sudetenland.
(4) On 15 March 1939, contrary to the provisions of the Munich Pact itself, the Nazi conspirators caused the completion of their plan by seizing and occupying the major part of Czechoslovakia, i.e. Bohemia and Moravia, not ceded to Germany by the Munich Pact.
4. Formulation of the plan to attack Poland: preparation and initiation of aggressive war: March 1939 to September 1939.
(a) With these aggressions successfully consummated, the conspirators had obtained much desired resources and bases and were ready to undertake further aggressions by means of war. Following the assurances to the world of peaceful intentions, an influential group of the conspirators met on 23 May 1939 to consider the further implementation of their plan. The situation was reviewed, and it was observed that “the past six years have been put to good use and all measures have been taken in correct sequence and in accordance with our aims,” that the national-political unity of the Germans had been substantially achieved, and that further successes could not be achieved without war and bloodshed. It was decided nevertheless next to attack Poland at the first suitable opportunity. It was admitted that the questions concerning Danzig which they had agitated with Poland were not true questions, but rather that the question was one of aggressive expansion for food and “Lebensraum.” It was recognized that Poland would fight if attacked and that a repetition of the Nazi success against Czechoslovakia without war could not be expected. Accordingly, it was determined that the problem was to isolate Poland and, if possible, prevent a simultaneous conflict with the Western Powers. Nevertheless, it was agreed that England was an enemy to their aspirations, and that war with England and her ally France must eventually result, and therefore that in that war every attempt must be made to overwhelm England with a “Blitzkrieg”, or lightning war. It was thereupon determined immediately to prepare detailed plans for an attack on Poland at the first suitable opportunity and thereafter for an attack on England and France, together with plans for the simultaneous occupation by armed force of air bases in the Netherlands and Belgium.
(b) Accordingly, after having denounced the German-Polish Pact of 1934 on false grounds, the Nazi conspirators proceeded to stir up the Danzig issue, to prepare frontier “incidents” to “justify” the attack, and to make demands for the cession of Polish territory. Upon refusal by Poland to yield, they caused German Armed Forces to invade Poland on 1 September 1939, thus precipitating war also with the United Kingdom and France.
5. Expansion of the war into a general war of aggression: planning and execution of attacks on Denmark, Norway, Belgium, the Netherlands, Luxembourg, Yugoslavia, and Greece: 1939 to April 1941.
Thus the aggressive war prepared for by the Nazi conspirators through their attacks on Austria and Czechoslovakia was actively launched by their attack on Poland, in violation of the terms of the Briand-Kellogg Pact, 1928. After the total defeat of Poland,
