    10.30   For a few seconds to port a mountain ridge towers high over the boat.  The boat must be close under land.  Because according to the Sailing Directions a current runs towards the coast came about and moved off slowly to await visibility improvement.  
    11.52 AC 8487 Surfacing U-boat bearing 340°T, 400 meters away.  I believe it is "U-134" and send a Recognition Signal which was not answered.  Dove away.  While diving I recognize the boat had a strange appearance.  No 2 cm anti-aircraft gun on the bridge, periscope was a bit more aft, net deflector carried over the periscope sheers.  Exact observation not possible because the boat could only be seen only momentarily in the increasing fog.  
      Vis. 50-400 meters  
    11.54   Crash dive.  Gave up running off on the surface due to the the poor awareness of the location of the enemy and exposure to attack.  Went to silent running.  
    12.00 AC 8488 Day's run:  185 nm  
    12.15   Sound bearing 350°T.  Went to periscope depth.  Both periscopes iced, cannot be extended.  To depth = 10 meters.  
    12.24   Sonar sounds (rhythmic chirping, like the German close sonar).  Consider it unlikely that "U-134" is equipped with sonar.  Noted in "WEYER" that the Finish boat is similar, the presence of Finish boats in the Arctic is unknown.  Again to periscope depth.  Visibility 300 meters.  Several sound bearings between 350° and 35°, a second sonar was distinguished.  
    13.20 Vis. 100-500 meters and ran in the direction of the last sound bearing.  
    13.55   3 shadows bearing 320°T, were recognized as German destroyers.  Recognition Signals exchanged with "Z 26" (Leader of the 8. Z-Flottille).  Report to Flottillenchef:  Sighted unknown U-boat 2 hours previously, probably "U-134".   
        Outgoing Radio Message:  Gruppe Nord from "U-454".  Unknown U-boat square AC 8480.

        I will carry out despite diesel repairs because otherwise the starboard diesel is unreliable.  Also, I think at night in poor visibility and uncertain navigation entering narrow unlit port off the English minefields is risky.

        From the debrief with the Kommandant of "U-134" it turned out that this boat saw a U-boat on 12 December about 04.00 hours that was believed to be "U-454" and whose recognition signal was not answered.  Boat had a German silhouette.  At this time "U-454" was in square 8540.

Comments of the Admiral Nordmeer on the K.T.B. of "U-454" for the period
    from 24.7. to 12.12.41  
1) To 4 December - 22.29 hours:
  The Transit Orders of the boat for the shift from the homeland to Kirkenes should have included a reference to the subsequent placing of the boat under the Admiral Nordmeer, formerly B.d.K.  Thus, the uncertainty incurred by the boat  from the signature of the Radio Messages might have been avoided.
2) To 11 December - 11.52 hours:
  As later noted, it could only have been an enemy submarine here, the co-location of 2 own U-boats should have been avoided by implementing measures, but I was not able to do this because I was not aware of the transit instructions of the boats, nor was my Command Center in operation and therefore lacked the necessary means of communications. On the ordered radio communications links for boats there were arrival delays up to 6 hours here or at the boats; therefore the boats could neither inform me of their location, nor or was I able to control the boats quickly.
  Incidentally, "U-134" also saw an enemy U-boat (on 12 December) that was taken as "U-454".
  It is unfortunate that good attack opportunities against enemy U-boats could not be exploited due to the presence of 2 own boats in the same sea area which were not mutually informed about their locations.

    13.12.41 Kirkenes alongside steamer "WESTSEE".  
    Condition of the boat:  Port diesel out of service.  Repairs could not be completed 11-12 December because the spare cylinder head did not fit (guide ring 2 mm too high).  Making it fit was not possible by on board means.  Starboard cylinder II leaks, clear for limited operation.  
    After reported to Admiral Nordmeer and determining repair possibilities on "SÜDMEER" Admiral Nordmeer orders:  Go alongside "SÜDMEER".  Make the spare cylinder head fit and install, weld the leaking cylinder head and retain as spare head on board.  If welding is not possible, report to Admiral Nordmeer who will get one from the homeland.  When "U-584" arrived it is checked to see whether the reserve cylinder head fits and if it can be used.  Admiral Nordmeer made a provisional report concerning the interrupted War Order, final War Order report to follow when the duration of the repair is known.

1.) Traffic.
  Ship traffic in operations area at large irregular intervals (every 8-14 days).  Small convoys with strong escort.  Convoy route apparently goes from 73°N to 74°N up to the longitude of Cape Gorodetzki to Charlow Island, from there using the Gorodetzki radio beacon, Swjatoi-Noss and Charlow to the south, at the latitude of Cape Teriberski part diverts to Murmansk.  Running in harbor and dispersal  points Cape Teriberski and Swjatoi-Noss.
  Under the coast in 4 nights no traffic was observed.
2) Defenses.
  The escorting warships of the convoy seemed to be more against attack from surface ships rather than against U-boats (only destroyers, no corvettes, behavior of the escorts after the attack on 17 January at 19.00 hours).  No regular patrols or U-boat hunts at the coast.  Patrol vessels only positioned at important points, if traffic was expected?  Patrol vessels are large modern fishing trawlers, apparently equipped with good listening gear and alert.
  Surveillance of the sea area by aircraft seldom and ineffective.
3) Navigation.
  During the dark period very difficult due to weather conditions, stellar observations are often precluded for days.  Plotting is uncertain due to the sea rapidly changing in direction and strength and difficult to detect currents.  Sounding only of limited use due to inadequate depth notations.  Own radio beacon at Vardö is strongly deflected by land in the sea area off Bären Island and the Murmansk coast.  Russian radio beacons at the Murmansk coast give good bearings, only work when traffic is expected, then however on the frequencies and identifiers set forth in the "Nautical Radio Service".  Bearings were taken on:  Kanin Noss, Cape Gorodetzki, Swjatoi-Noss, Som Ostrowo (Charlow Island), Cape Teriberski, Sosnowetz.
4) Weather.
  Weather forecast by on board weather map Adm. Nordmeer in general good, opposite in direction sometimes then the forecast.
  The rapid change in wind direction and strength, the sudden arises and abating of the Sea State is striking.
  Visibility conditions at darkness are often surprisingly good, especially with Northern Lights.  On closing the coast initially on land a bright glow is distinguished.  Visibility towards land was always greater than visibility to sea, and greater then the prevailing visibility conditions.
5) Behavior of the crew.
  The crew proved themselves in the sometimes severe stress from temperature and Sea State.  Falling ill occurred only as mild colds.
  The work of the diesel personnel is particularly emphasized, they took care of arising malfunctions with expertise and great commitment.

Comments of the Admiral Nordmeer on the K.T.B. of "U-454"
for the period from 13.12.41 to 20.01.42.
1) To 15 January - 15.17 hours:
  The cited radiogram concerned new transmitting times of the beacon at Vardoe and was addressed to Group Schendel
2) To 17 January - 05.07 hours to 06.43 hours:
  The aggressive approach to the patrol vessel and the tenacious holding on deserves recognition.  Despite initially unfavorable position it was correct to use the torpedoes, since the boat was expressly informed of the importance of the destruction of even the smallest vessels and the boat already on the return transit had no reason to take account of torpedo consumption.  The energetic use of weapons then led to a complete success.  According to the circumstances destruction of the enemy can be assumed with certainty.
3) To 17 January - 11.05 hours:
  The outgoing radio message sent at that time with the position report  of the enemy convoy was not received. The first radio message, with information of the convoy, was received at 18.34 hours and did not contain information on the location of the enemy.  The attack on the convoy was joined with foresight and determination.
  Also the radio message of 14:34 hours with location, course and speed of the enemy convoy was not received, likewise also the next two radio messages of 14:55 and 15:42 hours.  This fact was known to the boat, because the radio messages were not repeated by Control. Therefore it was necessary to specify the location of the convoy with every new message. The radio message of 18.37 hours concerning the convoy lacked a location report. The boat was not immediately prompted for a position report, not to unnecessarily tie up the frequency and because it was expected with certainty that the boat would report its own location.  Also in the radio message at 18.55 hours, in which the breaking of the contact was reported, a position was not given. The position was eventually reported 20:36 hours by special request. With timely and ongoing reports of enemy position until repeated by Control, getting the other two boats to the convoy would probably have been possible.
  The attack initiated at 18.31 hours against the convoy was very difficult due to the clear starry night with northern lights behind. It was carried out by the boat with tactical skill. Especially noteworthy is the shot against the target up to 4600 meters away. The torpedoing of a destroyer and a steamer in the
- 2 -
  first portion of the attack can be considered as certain.  The attack initiated at 22:09 hours after regaining contact was again very difficult due to the poor visibility of the vessels under the dark horizon and the long range of 4000 meters.  Again, the superior achievements deserve special recognition.
  The abandonment of the contact on the convoy at 23:49 hours was not correct, even though the boat had no more torpedoes available. The convoy had to run a long time before it was beyond the grasp of U-boats.  With continuous contact holding there might well have been an opportunity for the other two boats at sea to be brought up, this had to be considered especially with slow running damaged vessels.
  Overall, the good performance of the boat during its first remote patrol is worthy of special recognition.

Comments of the Befehlshabers der Unterseeboote
on the Kriegstagebuch "U-454" from 13.12.41 - 20.1.42.
                  The boat is not operationally subordinated to B.d.U.  
                  A very well executed patrol with a beautiful success.  Good shooting.  
                  The incomplete contact keeping reports were incorrect, as was the unfounded breaking of contact.  Stay in touch by all means to bring up other boats.
