          1.)  Order Gg. 458/0 is suspended until further notice and is to be returned to half-flotillas.  
          2.)  The last observations of the UB-boats do not give any reliable clue as to which base the English capital ship formations are currently staying at.  An intercepted radio message from 12 September appears to indicate that 1st Battlecruiser Squadron is at Scapa Flow.  
          3.)  The U-boats, ready for action, are to occupy the waters off the eastern and northern English naval ports against warships at once, and were distributed as follows:  
 
Tactical No.  1 - U-54 - North exit of the Minch,
      "       "     2 - U-55 - Sule Skerry (against warships leaving Scapa Flow for exercises to the NW)
      "       "     3 - U-52 - NW coast of the Orkneys,
      "       "     4 - U-20 - East of the Orkneys between the latitudes of Sumburgh Head and Out Skerry
      "       "     5 - U-24 - East of the Orkneys between the latitudes of Out Skerries and Pentland Firth,
      "       "     6 - U-44 - East of the Orkneys between the latitudes of Out Skerries and Pentland Skerries and 58° 15'N
      "       "     7 - U-69 - Between the latitudes of 57° 45'N and 57° 20'N
      "       "     8 - U-66 -        "               "          " 57° 20'N  "  57°N
      "       "     9 - U-64 -        "               "          " 57°N        "  56° 40'N
      "       "     10 - U-65 -        "               "          " 56° 40'N  "  56° 20'N
      "       "     11 - U-45 -        "               "          " 56° 20'N  "  56°N
      "       "     12 - U-49 -        "               "          " 56°N        "  55° 40'N
      "       "     13 - U-50 -        "               "          " 56° 40'N  "  55° 20'N
      "       "     14 - U-32 -        "               "          " 55° 20'N  "  55°N
      "       "     15 - U-56 -        "               "          " 55°N        "  54° 40'N
      "       "     16 - U-57 -        "               "          " 56° 40'N  "  Flamborough Head.
 
          4.)  When encountering enemy forces, as soon as you are lucky enough to make your own attack, you must give the other U-boats a reconnaissance signal according to F.d.U. 12027 F from 30 August 1916.  
          Arkona repeats these reconnaissance signals immediately and at the next Program Times.  
          Otherwise, Radio Message transmissions from U-boats should be restricted as far as possible. Boats that only have 2 Radiomen need to be manned from 8.00 - 07.00 am at Brügge and Nauen times only.  
          5.)  From 22 September begins again the period in which airship attacks on England must be expected.  
          On the days when airships took off for these attacks, keywords were radioed to the U-boats by S.M.S. "ARKONA" 08.00 - 09.00 PM every 15 minutes, from Brügge and Nauen at program times between 10.00 PM of the same day and 07.00 AM of the following day.  
          The keywords are different for Arkona, Brügge and Nauen, otherwise chosen arbitrarily; however, they all begin:  
 
on 22 Sep. (from 08.00 PM 22 Sep. - 07.00 AM 28 Sep.) 23 Sep. with Letter K
  "  23 Sep.               " 23 Sep. -       " 24 Sep.    "       "     R
  "  24 Sep.               " 24 Sep. -       " 25 Sep.    "       "     E
  "  25 Sep.               " 25 Sep. -       " 26 Sep.    "       "     U
  "  26 Sep.               " 26 Sep. -       " 27 Sep.    "       "     Z
  "  27 Sep.               " 27 Sep. -       " 28 Sep.    "       "     E
  "  28 Sep.               " 28 Sep. -       " 29 Sep.    "       "     R
  "  29 Sep.               " 29 Sep. -       " 30 Sep. again with Letter K and so forth
          According to observations of the airships on their last voyages, the English, if they expect airship attacks, lay out one or more lines of cruisers, destroyers and patrol steamers along the east coast up

  to 60 nm to sea.  
          6.)  After being selected, half-flotillas give boats that have their waiting stations south of the Firth of Forth the only available M Z to test against any type shallow draft vessels (destroyers, trawlers, etc.). Such opportunities to use torpedoes with M Z are to be exploited.  
          7.)  The boats return from these waiting stations in such a timely manner that they return on October 9th. again to common use full use work.  The boats return from these waiting positions in such a timely manner that they return on October 9th are fully usable again for collective use.  
          8.)  UB-35 lies off the Firth of Forth.  Expect UB-27 to be deployed to Blyth, Firth of Forth, Pentland, Firth or Moray Firth.  On its departure will be given Program Times for two days through Brügge and Nauens.  UB-27 departs to position "1" ("2, 3, or 4").  
          9.)  Own mines are located in the following areas:  
          a.)  Between Cape Wrath - Nun Rock - 59°N, 4°40'W - 59°N, 4°20'W - 58°45'N, 3°W - 583°8.5'N, 4°W;  
          b.)  Between 59°10'N and 59°05'N, 330'W and the west coast of the Orkneys;  
          c.)  In Moray Firth west of 2°W and south of 58°15'N;  
          d.)  In the Firth of Forth west of St.Abbs Head and south of Isle of May;  
          3.)  West of 1°30'W between the latitudes of 55°48'N and Coquet Island.  
          Further the North Minch south of the latitude of Tiumpau Head as well as St.Magnus Bay (west side of the Shetlands) between latitudes of Esha Ness and Fouls Island as well as longitude of Foula Head are to be regarded as mine suspicious.  
          10.)  This order is not to fall into enemy hands.
