    09.07 FJ 6235 Double shot from tubes I and IV, with target angle 43° bow left, 10 knots, estimated range 400 meters, tube I T 3, depth 7 meters, MZ on, tube IV Eto depth 4 meters, salvo at 3 seconds, offset 17°.

        Miss.  Assumption, due to the short range the torpedoes had not steered in yet and missed the target.

    09.30   1 min. 38 seconds after firing from tube III a sharp metallic impact is heard in the boat.  Apparently a Pistol failure of the T 3.  Computed distance 1500 meters.  
        Shot from tube II missed.  Conclude that target speed was overestimated.  Aiming point was after edge of bridge, thus forward, thus torpedo with offset 21.5° with target angle of 115° possibly passed ahead.

        Shot from tube IV on tanker type Empire Oil in left column.  Target angle right 90°, speed 8 knots, estimated range 2500 meters.  
        Next turned off for shots from tubes V and VI on tanker type British Zeal in the starboard outer column.  Target angle right 110° and 120°, speed 8 knots, estimated range 900 meters.  
        Tube I, II and IV T 3 with M.Z. on, tube III, V and VI Etos.  All depths 4 meters as ships were traveling in ballast.  
        After firing turned on convoy reciprocal heading at A.K and ran off into the seas.  While running off observed hits with flash and explosion column on 2 freighters and tanker type Empire oil, on 6000 GRT tanker faint glimmer observed.  
        Immediately thereafter the destroyers shoot star shells. Convoy has in the meantime turned to 170-180°.  The effect of hits on the targets not visible due to the indistinct situation, in which the targets partially block themselves, the dazzling light of star shells and overcoming strong seas.  In the boat in the order of firing, six distinct torpedo detonations were perceived.  Stop watch times approximately agree with estimated distances.  
        All hits, particularly the two from tubes V and VI, heard loudly in the boat.  Hit effect tubes V and VI not observed visibly, the tanker was already at target angle 180°.  Use of binoculars not possible due to spray.  In addition glare caused by star shells.  
    04.50   Irregular star shell shooting by the destroyers, some of which are beside and over the boat.  
        Judging from the number of muzzle flashes there are four of them.  Apparently the destroyers are firing by radar detection, because each time the fire is aimed very well after the respective breaks.  The boat is not hit however.  
    06.04   Ran off to the east and reloaded.  Intention is to look for survivors or damaged ships.  
    07.03   Flickering light from the shooting location bearing 220°T.  Headed towards it.  
    07.30 Moonlit Light is from the momentarily blazing deck lighting of a floating steamer.  Closing is not possible, there are two destroyers circling the drifting ship at 4000-5000 meters.   Did not conduct surface attack because of brightness of the moon.  Brightness insufficient for underwater attack.  Decided to attack underwater after the beginning of dawn.  
    08.00 FB 9379 Ran off, in order to observe from afar.

    13.08 FB 9299 Distance about 4000-5000 meters. tanker is of type Empire oil listing to starboard and lies with the stern deep in the water.  Forecastle is high above.  Therefore ship swings strongly.

        Anderson-type destroyer circles with varying speed around the tanker.  Stops from time to time, apparently to listen.  Tubes V and VI are made ready for firing.  
    13.20   Shortly before firing a flying boat Catalinia-type is sighted, heading directly towards the periscope.  Went quickly to 80 meters.  
    13.35   Again to periscope depth.  
        Flying boat circles continuously very low around steamer and to above the diving place.  Started approach again.  Tanker moves fast and continuously turns back and forth in the wind, constantly changing its heading.  
    14.05   Destroyer to windward of the tanker, suddenly goes to high speed with bow angle approximately 0°.  Destroyer observed by periscope to approximately 3000-4000 meters, then dived to depth A plus 80 and turned off.  At depth A plus 80 numerous failures, disorders and leaks of auxiliary machinery and other important operating equipment occur (pumps, stern tube, exhaust gas valve, vents), whose repair is later necessary.  
    14.35   The G.H.G. partially operable, nothing heard.  Again to periscope depth.  2 Catalina flying boats over tanker and the surrounding area, very low.  Destroyer circles steamer stopping occasionally.  Ship is now substantially deeper, stern is almost completely submerged.  At the signal mast a red burgee.   Distance now 6000-7000 meters target angle 160°.  
    15.15   Ran off to the ENE at low speed, in order to return again to the attack.

        speed 19 knots, ship is American of type "Mariposa".

    13.30 CF 4391 Double shot from tubes I and IV target angle right 85° Etos depth 6 meters, target speed 19 knots, distance 3500 meters.  Missed.  
        By diving the boat did not remain at high speed long enough to close the distance.  Distance 3500 meters is too far with this fast ship.  Explanation for miss is probably target speed estimated one knot too low.  Steamer runs reliably 20 knots.  That results in a difference of 2 degrees at 3500 meters or approximately 150 meters distance at the target.  Estimated target length is approximately 180 meters.  At target speed of 19 knots the right torpedo (75 m ahead of the aiming point) should hit.  A 1 knot speed difference results in a torpedo passage of 150 meters at the target to the left.  Thus the torpedo probably passed close behind the stern.  Too bad.  
        Shot from tubes II and III, loaded with Atos, estimated range 3500 meters, sea state 2-3 and target speed 20 pointless and therefore not fired.  Tail shot with now broad target angle is hopeless since range is too great.  Feasible distance with shot tube I and IV: "about 500 meters".

        Own machine gun does not fire, despite the order to do so at the moment of the illumination of the searchlight.  The cause of the failure could not be determined afterwards.  The machine gun was cocked and on safety.  At the next firing opportunity 5 hours later the weapon functioned perfectly.  Whether an operating error was present, could not be determined.  Afterwards the gunner says he could not fire the unsafed weapon despite repeated strong pulling of the trigger.  
        Since bombs were all intended for U-126 which apparently dove and is intact, the Kommandant decides to crash dive when the aircraft turns away.  Before closing the tower hatch a flickering light and smoke is noticed at the attack position, apparently a flare and smoke-bomb.  Nothing is seen of U-126 in the darkness.  
        After crash dive to 40 meters immediately attempt contact by underwater telephone, however receive no reply.  In the boat 6-8 short dull bangs are heard, similar in tone to

Went to periscope depth.  Nothing seen.  All underwater telephone signals remain unanswered.  The situation is unclear.  If U-126 also dived, and is listening on the underwater telephone there should be an answer.  If the boat remained surfaced, contrary to our impression, contact is now lost.  It was agreed between the two Kommandants that in the case of detection by the enemy to continue submerged.  From the conjecture of the Kommandant that U-126 did not dive after the unsuccessful bomb attack but at the next opportunity, it may be that the distance is so large that underwater telephone communication is no longer possible.  Therefore the decision was made not to surface.  Crucial for this determination are the observation of the Kommandant and the entire bridge watch, that the bomb attack was unsuccessful, and that U-126 remained undamaged and dived even earlier than own boat.

Commentary of the Kommandant in Chief U-boats

 
 
On the K.T.B. of "U-154" (Kusch) from 8.1 - 6.7.43.
 
 

 

 
 
First undertaking of the Kommandant after taking over the boat (Schuch). The first operation for the boat into the South Atlantic.  The attack on 8 May was unfortunately unsuccessful first because of a miss then because of pistol failures.  Air protection made subsequent efforts of the Kommandant more difficult.   The attack of 28 May was well done and skillfully driven.  Success very pleasing!
Concerning the 3 July:  The Kommandant behaved correctly during the aircraft attack, an energetic search for "U-126" would have been appropriate.  In addition to valuable experience, the first patrol brought the Kommandant a beautiful initial success.
