One of the missions of von Papen, as German Ambassador to Austria, was to effect a change in the personnel of the Austrian Cabinet headed by Chancellor von Schuschnigg and to eliminate anti-Nazi opposition, particularly in the Ministry of Interior and Security. (2246-PS)
The German Reich applied economic pressure upon Austria. One of the means adopted was the law of 24 March 1933, which required payment of 1,000 Reichs Marks by every German crossing the border into Austria (3467-PS). Kurt von Schuschnigg, former Chancellor of Austria, in his affidavit of 19 November 1945, described this economic pressure upon Austria by Germany in the following words:
“* * * During my tenure of office as Federal Chancellor of Austria, more particularly on the 11th day of July, 1936, I negotiated with the then existing government of the German Reich, and with Adolf Hitler, an Agreement more particularly known as the Agreement of 11 July 1936.
“I further depose and say that prior to the consummation of the aforesaid Agreement, the German Government had placed certain economic barriers against trade between Germany and Austria such as—to-wit—the 1,000 mark barrier which said barrier provided that any German citizen who crosses the border of Germany into Austria is obliged to pay to the German Government the sum of 1,000 German Reichs Marks for the privilege thereof—Austria had been accustomed before this edict of the German Government to receive into Austria some one hundred thousand visitors from Germany annually.
“I further state that the aforesaid barrier placed against Austria was extremely injurious to Austrian agriculture and industrial interests.” (2994-PS)
Jodl stated in his diary that in 1938 the aim of German policy was the elimination of Austria and Czechoslovakia. The will of resistance in both countries was undermined by pressure on the government as well as by propaganda and the fifth column. At the same time German military preparations for attack were worked out (1780-PS). (“Case Otto” was the code name for the Austrian campaign, and “Case Green” was the code name for the battle plans against Czechoslovakia.)
Jodl also stated in his diary that when Chancellor von Schuschnigg announced the proposed plebiscite for 13 March 1938, Hitler was determined to intervene. Goering, General Reichenau, and Minister Glaise-Horstenau were called before Hitler. “Case Otto” was to be prepared, and the mobilization of army units and air forces was ordered on 10 March 1938. The march into Austria took place on 11 March 1938. (1780-PS).
(12) Hitler and the Nazi conspirators completed the annexation of Austria by decree. On 11 March 1938 Hitler issued a directive regarding “Case Otto” addressed to the German armed forces, classified Top Secret, in which he stated that, if other measures proved useless, his intentions were to invade Austria with armed force. The directive prescribed operational duties and assigned objectives. It further provided that resistance was to be broken up ruthlessly with armed force. (C-102)
Later on that same day, at 8:45 p. m., Hitler issued a second directive, which stated in substance, that the demands of the German ultimatum to Austria had not been fulfilled, and for that reason the entry of German armed forces into Austria would commence at daybreak on 12 March 1938. He directed that all objectives were to be reached by exerting all forces to the full as quickly as possible. (C-182)
On 13 March 1938 Germany in violation of Article 80 of the Treaty of Versailles, formally incorporated Austria into the Reich by decree and declared it to be a province of the German Reich. (2307-PS)
