5 The Wehrmacht authorized Prague, 5. 1. :2.. go to the Reich Protector in Bohemia and Moravia Abbot Ia 1 Nr. 1445/41. Instructions No. 16 Geletin! 1.) Confidentiality. Due to the order OKH (Chef H Rüst and BdE) AHA/In 7 Nr. 7415/4l go. From 13.1l.41 it is announced: Various observations of telephone traffic in recent times prove that listening to long-distance calls is partly possible by talking, partly by means of radio equipment. All telephone lines in the Protectorate (also the special networks of the Wehrmacht, the Luftwaffe and the public authority network) are not wired because they are not secure through offices, run with most Czech occupation and a technical security against the interception can not be taken. Furthermore, in the protectorate with organized enemy interception must be reckoned with. These facts once again give cause to point out that every conversationalist must always be clear that he, like his interlocutor, also gives material into the hands of the second directing service, which can thus be evaluated for the hostile warfare. The fact that such cases of espionage are not known to the interviewee, or that there is no suspicion for him to accept them, or in his opinion the long-distance conversation must be conducted in the manner he considers necessary, does not relieve him of his duty to keep secret in favour of the German warfare. Any violation of this secrecy he carries with the extreme consequences. The commanders of the troops and the officers of the department have to point out the subordinated units and the personnel from time to time. to the caution required in the protectorate in the conduct of talks. (HWNO Abt. I Nr. 20ll/41. dated 10.12.1941). 2
