Fall Grün

All you want to know about Fall Grün

Before World War II, Fall Grün (Case Green) was a German plan for an aggressive war against Czechoslovakia. The first draft of the plan was made in late 1937, with new versions coming as the military situation and requirements changed. The final version scheduled the attack to September 28, 1938, but as France and the United Kingdom were reluctant to go into war for the sake of Czechoslovakia and expressed political will to avoid it at all costs, the execution of the plan was postponed and later, after the Munich Conference that took place on September 30, 1938, the plan was completely abandoned.

As Czechoslovakia ceded Sudetenland to Germany, it lost the most of its border fortifications and was no longer in a defendable position. Eventually, it was invaded and annexed by the Reich on March 15, 1939 (Unternehmen Südost or Operation Southeast) with minimal resistance.
