O p e r a t i o n s  O r d e r
  
for Auxiliary Mine Ship  " P A S S A T ".
 
     
 
A) Information on the Enemy.
      The presence of the cruiser "CANBERRA", "ACHILLES" and "PERTH", as well as the auxiliary cruisers "MANOORA" and "HECTOR" may be expected in Australian waters.
              The cruiser "ADELAIDE" was last reported in Noumea, French New Caledonia
              Nothing is known of the movements of these warships, as well as organization strength and operations of the patrols off Straits and entrances.
              Morning and evening air reconnaissance is to be expected.
       
B) Own Warships.
      Except for "PINGUIN" at the moment no own warships are in Australian waters.
       
C) T a s k :    
    1) "PASSAT" hereby receives the task to foul the entrances of the B a s s      S t r a i t with mines and thereafter unite with "PINGUIN".
    2)  If "PASSAT" is prevented from carrying out the task by being caught, the ship with the valuable cargo must be prevented from falling into enemy hands again by demolition and opening the valves. "PASSAT" carries no weapons for defense. Set war flag only when sinking.

    3) If the planned deployment of the mines is disturbed by hostile influence, the fouling is to be carried out elsewhere at one's own discretion in accordance with the tasks set.
       
    4) After completion of the mining tasks, a meeting place with "PINGUIN" is to be steered to away from any steamer traffic and while avoiding any vessel unseen.
              Meeting point:  Square = JF 33
                                    Latitude = 31°30'S
                                  Longitude = 101°30'E
      Waiting period at the meeting point from 12 to 20 November 1940.
       
      Should "PINGUIN" not be met by 20 November, handle by own means, initially strive to reach Ship 36, that is expected to be in transit to the homeland through the Indian Ocean.
       
E) Message provisions see attached Communications Order.
 
     
     
     
                                                                                                        
     
     
     
     
     
     
 

 

     
                                                       To Enclosure 20 Kriegstagebuch I  
                                                                                               Enclosure 1 to Operations Order  
                                                                                                 Auxiliary Mine Ship "PASSAT"   
     
C o m m u n i c a t i o n s    O r d e r
for the Auxiliary Mine Ship " P A S S A T ".
     
          The basis for the message traffic are the radio instructions and key documents of the HSK for auxiliary ships. In amendment and addition the following transmitting instructions:  
          The radio documents must not fall into enemy hands under any circumstances. Prepare containers with weights for sinking or keeping gasoline or other liquids ready for destruction by fire. Transmissions may only be made with the permission of the Kommandanten.  
          As call-sign for HSK are to be taken:  YTZQ and WIHB.  
          As call-sign for auxiliary ship:               CPDT, CBUK, CREF.  
                  (with first transmission use the first call-sign)  
          Program Times in accordance with radio instructions of the HSK for auxiliary ships (Shortwave).  
          Wavelengths:  HSK transmitter wavelength  63.90 meters 4695 kHz  
                                Tender      "               "           36 meters (in special cases 714 meters)  
  For reports to HSK 36 meters were used.  HSK answered on 63.90 meters and confirmations 5 minutes after ending of the transmission by:  ve ve ve dit dit.  After confirmation by HSK the auxiliary ship transmits on his transmit wavelength (36 meters): ve r tu.  
          Reverse procedure if HSK transmits first.  
          The transmission is made five minutes after the beginning of the Program Time at a time that is as convenient as possible for the transmitter. If the radio message was sent during the day without an acknowledgment, the radio message or signal is repeated once at dusk and possibly once at night.  
          Special attention is required when observing the HSK wavelength at the time of the meeting; from November 12 to 20 November at 16:00 hours GMT daily. From 12 November, the ship can also send the message on 714 meters at the Program Time 16:15 to 16:30 hours GMT, even from a greater distance, if the shortwave is out of service. Other longwave Program Times are not

  occupied by the HSK. The ship is not to expect any orders on the longwave and does not need to occupy them on the receive side.  
          Should the ships miss the meeting point due to unfavorable weather conditions, the HSK continues on its shortwave (63.90 meters) by the group:  
                  - KPLG - (given several times)  
for the delivery of bearing signals on 714 meters. If possible, this request will be issued by the HSK at Program Time 04.00 hours GMT.   10 minutes after receiving this group, the auxiliary ship transmits on 714 meters: vw vvv test de cref. The dashes of the "v" are transmitted for a long time, as if a ship were checking its transmitter. The radio name should not be recognized clearly if possible. The transmission should not last longer than one minute. 
        In addition, the auxiliary ship continuously occupies 600 meters with loudspeakers, possibly on the direction finder. Otherwise, B-Dienst is carried out on the medium wavelengths 150-220 meters and shortwavelengths 18, 24, and 36 meters.  GBMS radio calls are to be recorded. In the event of distress messages from English ships and radio jamming, immediately move to a wavelength  of 600 meters and observe and assess the jamming radio. Write down everything if possible. Turn on the automatic alarm if no watchman is present in the radio room.
          In case of emergency, everyone has a radio message with the relevant content, encrypted using the valid key, ready to go. The radio message is sent at a wavelength of 600 meters if the distance is short, otherwise at a wavelength of 36 meters. This is only possible in the case of capture or self-sinking and, like every Radio Message, is only sent on orders of the Kommandanten.  If there is no time left to send this Radio Message and in extreme emergencies in the event of a suprise arrival, a RRRRRR or QQQQQQ message can be sent in the form of a "distress message" on orders of the Kommandanten (with the prescribed name "STORSTAD" and position).  
          The short signals are given to the auxiliary as shown in the Short Signal Book, but with a call-sign, without separating it from the groups. Introduction by several vvvv with a long dash.  
          Additionally the following were agreed upon for as planned Short Signals:  
 
  jadf Task completed t as planned,
  svjg Task 1 completed,

  szof Task 1 and 2 completed,
  hpfb Task 2 and 3 completed,
  ytnk  Cannot reach meeting point,
  puay Can first reach meeting point 3 days later,
  csab Can first reach meeting place 8 days later,
  jfua Can reach meeting point 3 days early.
 
     
          These special short signals are not encrypted, but are sent in the form shown below. They are disguised as a radio call-sign  
     
 
  Auxiliary: A special Short Signal jadf is to be transmitted. The ship calls ytzq (call HSK) de jadf . . at several times. This call is transmitted several times and then ended, so that to the outside world it looks like any other call.
 
  From 29 October 04.00 hours GMT to 31 October 20.00 hours GMT the HSK will continuously occupy 36 meters.  
          To submit the execution report, the Program Time at 16:00 hours GMT on November 1, 2 and 3 should be selected if possible. At this time, the HSK will set up several receivers to pick up the Short Signal.
