Fall Grün (German for 'Case Green') was a pre-World War II plan for the invasion of Czechoslovakia by Nazi Germany. Although some preliminary steps were taken to destabilise Czechoslovakia, the plan was never fully realised since Nazi Germany achieved its objective by diplomatic means at the Munich Conference in September 1938, followed by the unopposed military occupation of Bohemia and Moravia and the creation of a nominally independent Slovakia, in March 1939.

Background

The plan was first drafted in June 1937, then revised as the military situation and requirements changed - such as after the annexation of Austria by Nazi Germany in March 1938. Following the May Crisis war scare of that year, the plan acquired a target date scheduling the attack for not later than 1 October 1938. The directive, signed by Adolf Hitler on 30 May 1938, indicated it was his "unalterable decision" to destroy Czechoslovakia in the near future.[1]

Czechoslovakia's principal ally, France, in conjunction with Britain, pursued a policy of "Appeasement" towards Nazi Germany, culminating in the Munich Agreement, signed on 30 September 1938. The agreement, between the leaders of Britain, France, Germany and Italy, transferred the mainly German-inhabited regions of the country (known as the "Sudetenland") to Germany.[2] The territory concerned contained Czechoslovakia’s strategically significant border fortifications,[3] and, as a result of the loss, the plan for a military attack was no longer relevant. The destruction of Czechoslovakia was completed in March 1939, when Slovakia became a nominally independent state under the influence of Nazi Germany. The remaining western parts of Czechoslovakia were occupied by Germany and became the Protectorate of Bohemia and Moravia.[4]

The name Fall Grün was later assigned to the plans for an invasion of Ireland.

Plan of attack

In addition to specific military assignments, the directive for Fall Grün also focussed on political preparations. The Czechoslovak authorities were to be intimidated by belligerent threats from Nazi Germany and the ethnic German minority population within the country organised to support the military operations. An incident would be staged to provide a pretext for opening hostilities. Attention was also to be given to encouraging Poland and Hungary to pursue their territorial claims against Czechoslovakia. [5]

The military campaign was to emphasise speed of action and an element of surprise. The aim of the army, in coordination with the air force, was to stage a surprise attack, penetrating and outflanking the border defences adjacent to Germany. The attack was to be carried out by 4 army formations massed along the western borders of Czechoslovakia. The main trust of the campaign would come from the west in the direction of Plzeň and Prague. Simultaneously, a pincer movement from the north towards Olomouc and the south towards Brno would prevent the withdrawal of the Czechoslovak army eastwards into Slovakia. Even the Danube flotilla would be brought into action in support of the army. With future armed conflict in mind, the directive also required, wherever possible, for Czechoslovakia’s industrial capacity to be preserved.[5]

Undeclared German-Czechoslovak war

On 17 September 1938, Adolf Hitler ordered the establishment of Sudetendeutsches Freikorps, a paramilitary organisation that took over the structure of Freiwillinger Schutzdienst/Ordnersgruppe, an organisation of ethnic Germans in Czechoslovakia that had been dissolved by the Czechoslovak authorities the previous day because of its implication in large number of terrorist activities. The organisation was sheltered, trained and equipped by German authorities and conducted cross-border terrorist operations into Czechoslovakian territory. Relying on the Convention for the Definition of Aggression, Czechoslovak President Edvard Beneš[6] and the Czechoslovak government-in-exile[7] later regarded 17 September 1938 to be the beginning of the undeclared German-Czechoslovak war. That understanding has been assumed also by the Constitutional Court of the Czech Republic in 1997.[8]
