a. thorough preparation of the action against Czechoslovakia ("Fall Gruen"). See Part 2.
b. Maintenance of the previous "Fall Rot" (strategic concentration with the main effort against the West.) See Part 2.
c. Special preparations, mainly in the form of studies and deliberations within the Supreme Commands. See Part 3.
d. Preparatory measures, in case German territory is suddenly and abruptly violated with hostile intent by a foreign power. See number 3.
3. If in the midst of peace, German territory is suddenly and abruptly violated with hostile intent by a foreign power, armed resistance will be offered without any special order.
Therefore, the branches of the Armed Forces must empower their competent Commanders on the frontier or on the coast to take on their own authority, all measures necessary to repulse the enemy attack should such a case occur. (See Reich Defense Law (RVG) para. 2).
In no event, however, may the German Reich frontier be crossed by troops or aircraft, nor any foreign territory violated, without my order.
It will not be considered a violation of German territory (see 1st sentence of this number) if single sentries or patrols cross the frontier unintentionally and accidentally or through the over-eagerness of a subordinate commander, or if aircraft fly over the frontier due to faulty navigation, or warships sail in our German territorial waters with obviously no hostile intentions.
4. This directive concerns the uniform preparation for war and the general strategic considerations applying to the outbreak of the war. It will be augmented as necessitated by the various strategic concentrations by regulations dealing with matters of Special Administration and War Economy.
The directives necessary for the prosecution of the war itself will be issued by me from time to time.
