V. Reports of Success:
    U 160 - 1 ship  9,974 GRT.
       
VI. General:
  Increased danger from the air in the Bay of Biscay makes an alteration of orders for procedure on approach routes necessary.  Danger of mines in waters less than 200 meters in depth is to be regarded as greater than danger from the air as before, boats must therefore remain on the surface.  But as the danger of unexpected attack from radar-equipped aircraft is greater by night than by day, in future boats shall proceed by day, and submerged only in the extreme sections when daylight is not sufficient for the whole journey.  Increased danger from submarines must be reduced by steering zigzag course, and on the whole taken into account, as also the growing danger as our routes become known to aircraft and submarine.

II. Air Reconnaissance:  None.
       
III. Reports on the Enemy:
  a) 1) U 160 sank freighter of 8,000 GRT in ED 9865 on 18.7.  Westerly course.
    2) Situation U 575:  3 days north of Tobago - no shipping.  On morning of 17.7. 5 single ships seen entering passage, one patrol boat.  Fired 2 misses, one unexplained.  Sunk:  18.7. "San Gaspar" (12,910 GRT) in EE 7778, bound from Trinidad to Freetown.  2 sailing ships "Glacier" and "Comrade" sunk by gun-fire in EE 78 and 75.  Return passage.
    3) Situation U 437:  Hunted small fast freighter from DN 7861 to 7559 without success.  On 17. reported convoy consisted of 3 steamers, 3-4 destroyers escorted by flying boat, course 190, speed 18 knots.  2-spread long range shot with data exact at 2 10,000 ton steamers.  Was finally forced to submerge.  Heard loud explosions.  One steamer probably left sinking but this was not observed.  Lost contact.
    4) U 582 sighted patrol boat in EJ 6363.  Boat was observed and fired on with tracer.
  b)  None.
       
- 35 -
 
 
     

 

     
     
 
  c) U-boat sightings:  BA 93 - ED 9947 - DB 9532 - DM 2759 - DL 6674 - DN 8639 - DD 57 - CA 34 - BB 55 - CA 86 - DN 95 - DB 94 - DB 6282.
    Aircraft reported submarine in BE 41 - 42.
    Submarine attack in ED 99.
  d) None.
       
IV. Current Operations:
  a) Convoy No. 35:
    Contact was maintained.  Apart from U 162, which lay too far off, all boats made contact with convoy.  At 1157 U 126 reported same in BD 9591.  Boat was on return passage, short of fuel and all torpedoes expended.  He received orders to shadow convoy without consideration for fuel supply.  Convoy position report from U 126 at 1355:  BD 9831, course 1300, speed 7 knots.  Convoy then zigzagged sharply to the S. east.  Further shadowing reports received:  1520 from U 564 BD 9839, 1835 from U 108 BD 9942.  U 654 made contact at about 1900.  U 202 was attacked by corvette with gun fire and lay 30 miles astern of the convoy.  Boat received orders for return passage, as this was possible without refueling.  According to reports at 2135 convoy was steering 1600 and finally on southerly course.  Flying boats and sometimes night bombers often forced the boats to submerge and withdraw from the convoy.  But they always managed to regain contact.  At 0017 U 564 reported convoy in CE 3343; attacked at 0230, torpedoed 4 ships and was then forced off.  Messages received later, at 0352 from U 654 in CE 3375 and at 0500 from U 126 in CE 3391, led to the conclusion that the convoy separated.  It is more probable though that there was a large error in estimated position between the two boats.  In that case convoy would have taken up S. easterly course once more.  One after another all boats were forced to retire.  Contact was finally lost.  Boats continued to search on probable courses.  Towards morning U 108 reported having fired one 4-spread and one 2-spread and hearing 5 explosions.  No further observations.  Finally hunted by destroyers.  Operation continues.   
  b) 1) Group "Wolf" received orders at 1200 to proceed on reconnaissance strip course 2400, speed 7 knots, and to patrol between AK 4532 and AK 8585 at 2400, so as not to miss the expected convoy (reported by radio intercept) during night.
    2) U 89 operating on shipping proceeding from Boston via CB 1110 - BB 7770 and BB 7760.  Mainly convoys.
  c)  U 161 and U 508 scheduled to meet for handing over of torpedoes in DD 3385 on 21.7.
  d)  None.

    3) U 332 sighted Portuguese ship "San Miguel" in CC 8210 on course 2400.  Received orders to let ship proceed.  On 19.7. sank "Leonidas" (4,573 GRT) while on course 3100.  Took captain and engineer officer on board.
    4) U 461 outward bound on 28.6. sighted only one patrol ship on a S.W. course.
    5) U 402 started return passage on account of heavy damage to batteries.
    6) Situation U 84:  Heavy traffic from DM 1919 over 16 and 13 along 20 meter line.  Mainly during day.  Strong air, medium sea patrol.  Sank freighter of 6,500 tons on 19.7. on course 1850, position DM 1651.
    7) U 154 cannot remove oil track, and requests permission to operate in DO on that account.  Present position DK 6878, no traffic.
  b)  None.

IV. Current Operations:
  a) Convoy No. 35:
    U 108 and 564 searched sectors between 210 - 1400 without success.  As it was probable that the convoy was continuing on a S.E. course and boats lay in a favorable position for combined attack they received orders to operate from their own positions on convoy courses between S. and S.E. commencing from convoy position CE 3354 at 0200.  At 1257 U 126 sighted a mast for a short time in CE 3639, but could distinguish nothing further on account of bad visibility.  At 1335 U 108 sighted convoy in CF 1529 on S.E. course, but was seen by 2 corvettes and forced to retire.  U 126 commenced return passage towards evening as this was still possible without refueling.  U 564 reported, on demand, formation of convoy during previous night.  3 columns in line ahead, tightly formed, no long-range, and only slight close escort.  No organized patrol for the night was ordered.  Boats merely received orders to continue search in sectors between 180 - 1500, commencing from convoy position CE 1561 at 1430.  Only after U 654 and 564 had reported, asking for permission to continue search on 170 or 2100 according to circumstances, was the following distribution decided upon.  U 564 - 162 and 654 were to operate in succession from west to east in a given sector with enemy speed 7.5 - 9 knots.  U 108 was given freedom of movement.  Reasons for orders to continue search were as follows:
    1) Favorable positions of the boats.
    2) Presumption that convoy was not making for Gibraltar and would proceed on southerly course, as position at the time was well off the Azores.  Operation continues.  U 108 was subjected to long and heavy depth charging.
  b) U 509 was detailed to new position ED 11, and U 463 and 607 to CC 80.  U 154 to operational area ED 90.
    U 437 operating between DN 95 and 47, focal point off Windward Passage.
    At 1130 Group "Wolf" received orders to take up new patrol position between AK 5792 and AK 8997.  From 0800/20. to proceed on reconnaissance strip course 500, speed 6 knots in order to pick up westbound convoy reported by Radio Intercept Service.
  c) 1) U 66 reported special duty completed (minelaying off Castries, St. Lucia).
    2) U 332 refueled from U 461.  Took over 35 cbm and 14 day's provisions.
      Tanker reserves:  628 cbm.  1653 sets of provisions.
  d) None.

V. Reports of Success:
    U 84   - 1 ship  6,500 GRT
    U 332 - 1 ship 4,573     "
       
VI. General:
  a)  Operations of Group "Wolf" are heavily dependent on weather situation (continuous bad visibility).  After experiences of Group "Hecht" in June, and radio intercept reports, according to which the main route of convoys on the whole still seems to follow the Great Circle path, it can be presumed that had the weather been more favorable, the group would have found targets for attack.
     A change in the general weather situation with promise of better visibility cannot yet be foreseen.  I therefore intend if the present operation on convoy reported by Radio Intercept Service comes to nothing, to draw the boats across the convoy route off to the south, to re-fuel, and afterwards, according to weather conditions, to place them either in area northeast of the Antilles and Caribbean Sea as far as that is possible, or back in the Northern area.  In any case the result will be a fairly long operation.
  b)  Situation reports from boats in the American area show the following:
    1) In the sea area off Hatteras successes have dropped considerably.  This is due to a drop in the traffic (formation of convoys) and increased defence measures.  Of the boats stationed there in the recent period only two, U 754 and U 701 have had successes.  On the other hand U 701 and U 215 have apparently been lost, and U 402 and 576 badly damaged by depth charges or bombs.  This state of things is not justified by the amount of success achieved.  The two remaining boats (U 754 and 458) will therefore be removed.  With this development has set in which might have been expected earlier.
      For occasional operations by single boats and minelaying operations in harbor entrances, areas along the east coast of America will come under consideration as before.
    2) Gulf of Mexico and Caribbean Sea:
      Along the Antilles from Key West to Trinidad the formation of smaller convoys has been confirmed, as also in the Yucatan Straits.  These observations are confirmed by the announcement of the American Secretary of the Navy that the convoy system has been introduced in the Caribbean Sea but not in the Gulf.  Single ship traffic was observed in July off the Mississippi, western entrance to the Florida Straits and around Trinidad, while U 505 reported scarcely any traffic off the Panama Canal.  
      On the whole therefore traffic seems to have decreased, though for the time being this must be considered as temporary.  Explanation as follows:
     
a) by the formation of convoys
b) possibly by the taking off non-vital, internal American traffic, which must also have felt the effects of the loss of 500 ships since January and
c) possibly by the removal of traffic routes further cut to sea under convoy.  The sighting of a convoy in DD 78
 
 
 
- 39 -
 
 
     

 

     
     
 
     
  on course 170 might be an indication of this.  The focal points of attack in this area for the time being are the points where the heaviest single-ship traffic has been observed and can continue to be expected, that is, north of the Gulf ports and off Trinidad.
  Operations in the Gulf itself and in the Caribbean Sea must also be taken into consideration, since single-ship traffic is still to be expected there, especially at the exits to the Caribbean Sea.

IV. Current Operations:
  a) Convoy No. 35:
    As search for convoy proved unsuccessful the operation was broken off.  U 162 and U 108 were detailed to new operational area ED 81.  U 564 and U 654 were to operate for the present around the Azores until further orders.  Refueling from "Lima" has been arranged for both boats.  U 564 reports sinking of 4 ships he torpedoed.  Total about 23,000 GRT.  At 0834 on 21. U 654 sighted convoy in his sector CF 8272, on southerly course and medium speed.  According to dead reckoning this could have been the one we had lost, U 564 and U 162 received orders to operate on it.  U 108 continued passage for op. area.  Operation continues.
  b) 1) Group "Wolf" received orders to proceed immediately on course 320 speed 7 knots.  Aim was to contact a westbound convoy which according to radio intercept report lay in position AK 6455 at 2200/19/7. speed 6.5 - 7 knots.  At 0100 on 21.7. Group proceeded from reconnaissance strip AK 5415 - AK 8641 on course 2500 and speed 7 knots, in order to patrol between AK 4645 - 8573 from 0800 onwards.  Fog conditions in this area persist.

IV. Current Operations:
  a) Convoy No. 35:
     At 1350 U 654 reported that sighting was not convoy but 3 heavily smoking vessels (trawler type) and one destroyer, on easterly course.  Operations finally broken off.
    As proposed refueling from Lima could no longer take place, U 654 and 564 ordered to DD 90.  Here refueling was arranged from U 463.  U 162 received Op. areas EE and EO.
  b) 1) Group "Wolf" received orders to leave patrol position at 0100 22.7. and proceed on reconnaissance strip 2350, days journey 150 miles.  Refueling provided for.
    2) U 463 - 510 - 607 - 598 - 658 - 217 - 254 - 600 received new positions in DD 90 for purpose of refueling.

  d)  None.
       
V. Reports of Success:  
    U 160 - 1 ship  8,150 GRT.
       
VI. General:
  a)  Operation on Convoy No. 35, with 4 ships sunk and 5 hits, was crowned with success.  The successes were scored by the veteran boats as in the North Atlantic.  Of the others, 2
       
- 43 -
 
 
     

 

     
     
 
     (U 126 and U 202) were on return passage and therefore no longer fully prepared for attack.  U 162 not able to get within range of convoy from such a great distance, and U 654 got no chance to attack.  Operation was effected from time to time by rapidly altering visibility.
  b) According to orders of OKM-K in a number of IXc boats centrifugal blowers have been fitted instead of the 9 cylinder MAN motors made by Bueschi, because the Bueschi installations at first caused trouble in the workings.
    B.d.U. for his part tried as soon as possible to break off this replacement as soon as the cause had been removed, in order to keep the Bueschi blowers, whose working was certainly more dependable.  As the discontinuation of this arrangement was not effected, or could not be in the opinion of OKM-K, considerable misgiving was expressed with regard to the reliable working of these machines, especially in view of disorders caused by the new centrifugal blowers.  Danger exists that the operational efficiency of the boats will be impaired.

  Entered Port:  U 128 - Lorient;  U 584 - Brest.
  Sailed:  U 593 - St. Nazaire.
       
II. Air Reconnaissance:  None.
       
III. Reports on the Enemy:
  a) 1) Report from U 564 see para. IV a).
       
- 44 -
 
 
     

 

     
     
 
    2) U 509 sighted sub. conning tower in DO 6416 (possibly one of our own).
    3) U 582 sank American ship "Honolulan" (7,493 GRT) in ES 3457.  Course 3200, speed 8 knots.
    4) U 609 reports convoy in AE 8812 at 0656, consisting of about 5 steamers (No. 36).
  b)  None.
  c) U-boat sightings:  BB 4581 - CA 7988 - DA 93 - BB 4576 - DC 12 - DM 51 - EO 1271 - DO 7889 - DB 7747 - DM 2873 - DM 7228 - ED 9829 - DC 11.
    Submarine was attacked by army aircraft in DO 78.   SSS report from ED 98.
  d)  None.
       
IV. Current Operations:
  a)  U 564 sighted 2 battleships at 0932 in CF 7875, course 3250, speed 17 knots.  Boat was ordered to give shadowing reports for benefit of other boats in the vicinity.  According to dead reckoning U 162 ought to have been in position suitable for operating but after position report lay in fact too far off.  U 654 in CE 9889 attempted to reach the enemy.  U 564 reported enemy in CF 7844 at 1115, course 00, speed 15 knots, and in CF 7577 at 1254, main course north, speed 15.5 knots.  3 destroyers formed part of the force.  Boat dropped astern.  When U 654 also reported having no extra speed, he received orders to continue passage, as also U 564, if no contact was made.  Formation disappeared from sight at 1346.  Battleships were "Ramilles" class.  
  b Group "Wolf" received orders to proceed in search of traffic from EL 25, close in shore eastwards to ED 90.  Operate there according to previous situation reports.
  c)  None.
  d) 1) On 14.7. U 751 sailed from St. Nazaire, and up till now has made neither "passing" report nor answered numerous calls.  A number of sighting and attacking reports from English aircraft lead to conclusion that boat was destroyed by them.  The loss cannot be attributed to a mine since the route in question was run over on 10.7. and 15.7. without result.  Loss of boat must be reckoned with.
    2) U 576 reported bomb damage to shutter of main ballast tank on 13.5.  According to a further report from CA 8836 on 14.5. repair is impossible.  Boat proceeding with ballast tank 5 flooded.  Since then no reply has been received from U 576 in spite of numerous calls.  No attack reports from American aircraft or surface forces have been received, so no grounds exist for considering it lost.  There is always the possibility that the boat with flooded main ballast tank cut under at high speed (while being hunted by fast ship for instance).

II. Air Reconnaissance:  None.
       
III. Reports on the Enemy:
  a) 1) Convoy No. 36 and 37 see para. IV a).
    2) Situation U 84:  DM 1919 - junction for heavy convoy and single ship traffic to north, south and east.  On 21.7. in DM 1994 one freighter of 12,000 GRT torpedoed, out of a convoy on 3200, speed 8 knots.  Was forced off.  Protracted return passage.
    3) U 508 reported from DD 3799, having fired 3 spread miss at tanker on easterly course.  While continuing hunt, ship was seen to switch on navigation lights at dusk.  It was probably a neutral ship already reported.  Boat was referred to previous orders.
    4) U 510 reported freighter in CD 16, southerly course, high speed, contact lost.  Patrol boat sighted while proceeding through Iceland Passage, and 2 enemy submarines in AF 49.
    5) Situation U 89:  Hunted convoy on hydrophones from CB 1234 - 1723, consisting of 3-5 steamers, course 2100, speed 12 knots.  In thick fog attack on large tanker was ruined by a destroyer, 2 spread then fired on latter.  While diving 2 loud explosions were heard.  Gunfire before-hand

      at 200 meter range.  No contact.  
    6) U 129 sank "Port Antonio" (1,266 GRT) on 19.7. in DM 4152, course 550.  On 24.7. sank freighter of 4,000 GRT in DM 6464, course 3000.  Otherwise situation as reported.  Protracted return passage via DN 80 and DO 20.
  b)  None.
  c) 1) English aircraft attacked submarine in AE 8712 and reported 1 hit (U 609).
    2) U-boat sightings:  BB 52 - DB 5669 - AH 9819 - EB 25 - AK 7519 - DC 5532 - CB 17 - CG 85 - DA 9344.
  d)  None.
       
IV. Current Operations:
  a) Convoy No. 36:
     0900 U 600 reported operation on convoy in progress.  As boat lay 350 miles to the southwest of it, was ordered to continue passage.  A short while after U 254 asked for bearings and sighted convoy in AE 76 at 1507.  U 609 was bombed and forced to submerge.  U 254 continued to shadow.  Convoy then steered on general course 2950, speed 9 - 10 knots, consisted of at least 8-10 steamers, air escort provided by 2 Catalinas.  U 511 requested permission to operate at 1949 from AL 33, but was ordered to continue passage.  U 609 attempted to approach again from favorable position.  At 2230 convoy position AE 7294.  U 254 continued to report shadowing every 2 hours, but could not get in an attack.  Towards 0900/24 convoy in AE 7294 disappeared from sight.  Boat presumed destination of convoy to be Reykjavik.  Operation was therefore over.  Not a single boat made an attack.  The conduct of the boats will be examined on return.
    Convoy No. 37:
    U 552 a member of Group "Wolf", sighted convoy at 2106 in AE 7831 on course 2400.  Almost immediately U 379 reported convoy in AK 7823, medium speed.  Group "Wolf" received orders to attack, as also U 609 if position was favorable.  U 90 made contact with destroyer in AK 7585 at 2120.  Further shadowing reports from U 597 at 2320 in AK 7854, and U 379 at 2330 in AK 7819.  U 552 reported convoy in AK 7827 at 2225, course 2300, long range escort.  Boat's port engine out of order, and could only do 9 - 10 knots.  This was especially regrettable since it was the only boat with convoy experience.  Soon afterwards contact was lost.  As all the boats must have been in the vicinity, idea of combined attack was given up.  U 704 and U 379 reported search in directions 2350 and 2400 respectively.  Nevertheless convoy remained unsighted until morning.
  b) 1) U 132 requested protracted return passage via CE 55; received orders to operate in BB.  It was impressed upon him to keep away from the coast.
    2) U 173 operating in DO 30 and DP 10 on account of damaged periscope.

    3) U 509 proceeding via Mona Passage and DE 60 to DM 10 and 20.
    4) U 507 and 130 after refueling took up position in Op. area FC upper and middle third, or ES lower and FD upper third.
    5) Operation is planned for U 553 - 588 - and 593 in Belle Isle Straits.  For this new position AH 98.
  c) 1) U 203 took over invalid from U 564.
    2) U 161 completed refueling from U 462.

- 48 -
 
 
     

 

     
     
 
    2) U 510 fired 4 torpedoes at supposed sub. decoy ship which probably ran underneath.  Reliable data.  Position CC 6662, east course.
    3) Situation U 134:  Sea and air patrol along east and south coast of Florida as reported earlier.  On 19.7. in DM 2770 one destroyer and a number of patrol vessels patrolling up and down.  Between 21 and 24.7. in DA 93 and DB 47, great air activity, no shipping.  Withdrew on account bright moonlit nights.  Plan to proceed via DM 65 to DO 20.
    4) Situation U 754:  Shot which missed at 4,000 ton freighter in CA 9482, course 3500, speed 18 knots.  Probably a new ship camouflaged.  Otherwise no traffic.  Small to medium air activity.
  b) U-boat sightings:  CC 66 - BC 38 - EQ 21 - CC 6929 - BC 6283 - CA 32 - CA 94 - DB 59 - EE 72 - CA 3974 - CB 15.
     Submarine attack on American steamer in CC 6652.  
    Submarine fired on patrol boats off Hatteras.
  c) - d) None.
       
IV. Current Operations:
  a) Convoy No. 37:
     Since none of the boats had made contact Group "Wolf" received orders to take up patrol position at 1700 between AJ 9882 and BC 3597 in previous order of succession.  Convoy courses between 270 and 210 would pass through this line.  Enemy speed assumed to be 8 knots.  Before this order could be carried out convoy was again sighted by U 552 in BC 3387 at 1057/24.  Weather:  Slight cloud, visibility over 10 miles, slight swell from the northwest.  U 552 shadowed and reported position of convoy every hour.  Position at 2100 BC 3872.  After this general course southwest speed 10 - 12 knots.  One after another 6 further boats reported contact with convoy, i.e., U 71 at 1707; U 704 at 1722; U 454 at 1747; U 86 at 1800; U 597 at 2232; and U 379 at 2236.  Current convoy position reports gave no clear indication of what further course was to be.  Boats' dead reckoning estimations differed up to 30 miles.
     At 2357 U 552 reported that convoy in gusts of rain had zig-zagged and was now on a northerly course in BC 3841.  Further reports (one from U 379 that convoy disappeared from view at 0001 on course 1500, and U 454 which reported convoy on westerly course at 0048 in BC 3813) suggest that convoy divided during the gusts of rain.  At 0340 U 552 reported convoy position BC 3828, course 1600, speed 9 knots.  The convoy had therefore first steered a northerly and then an easterly course, and it is impossible that a part of the same had remained on a westerly course.
     U 552 attacked and sank 2 ships, total tonnage 16,000 GRT.  Was forced to submerge by gunfire during attack and lost contact.  Rising sea (6.7) as well as bad visibility made pursuit seem hopeless.  Boat reported last position of convoy as BC 3853 at 0500, course south.  None of the other
 
 
 
- 49 -
 
 
     

 

     
     
 
     boats were successful.  Operation continues.  Convoy was still uncontacted by morning.
  b)  U 754 and 458 received orders to operate on traffic running from Boston through CB 1110, BB 7770 and 7760.  Mainly convoys.
    U 254 and U 609 received waters off Reykjavik as attacking area.  Shipping expected from SE, S and SW.  Attention is drawn to barrage.  U 511 new position DD 90.
  c) - d) None.
       
V. Reports of Success:
  U 522 - 2 ships  16,000 GRT.

  d)  None.
       
IV. Current Operations:
  a) Convoy No. 37:
     Group "Wolf" proceeded on general course 2100, with the object of winning as much ground to the south as possible.  A more detailed plan was not possible under the prevailing weather conditions.  An encyphered exchange of signals between Command and C.O. of U 552 showed that attack would be very difficult on account of strong defense measures, and that the convoy was making full use of the sudden bad weather for alterations of course.  This would probably cause a number of the boats to lose contact.  U 86 while proceeding on southerly course as ordered sighted destroyer at 1346 in BC 6213 on course 1800, and convoy itself at 1754 in BC 6259, course 2200, speed 8 knots.
     Weather:  Wind SW 5-6, medium swell from the west.  
     Shadowing was continued until next morning without a break, the following position reports being made:  U 451 at 2108 in BC 6288;  U 86 at 2304 in BC 6513;  U 379 at 0343/26 in BC 6423;  U 71 at 0415 in 6425 and U 379 once again at 0652 in BC 6417.  At 2115 U 704 sighted 2 freighters on SW course in 6436, but soon lost contact.  U 454 was forced off after shadowing report at 2108, and came across single ship at 0103 in BC 6561 which he recognized later as a neutral.  U 607 commenced operations immediately after first contact report from U 86, and sighted convoy at 2333 in BC 6517.  At the same time U 597 came upon convoy in same grid position.  Differences in position estimations from the other boats ranged up to 12 miles.  U 597 reported convoy proceeding in 2 columns, consisting of 12-14 steamers, and 1 corvette to starboard.  Submerged attack unsuccessful.  U 552 asked for bearings several times during the night, but did not make contact with the convoy.  U 43 attacked at 0300, but was forced off by destroyers and depth charged.  U 607 attacked at 0757 in BC 5693 and scored 2 hits on 8,000 GRT freighter as well as one hit on unknown target; was finally forced to withdraw.  Convoy last reported steering 2300 degrees, speed according to dead reckoning 10-12 knots.
     Operation continues.
     The interchange of cypher messages between 1145 and 1300 has again proved an excellent medium for detailed information, and established clarity conditions on the spot.
    Under difficult conditions it was again only the veteran boats that managed a successful attack.  Nevertheless the carrying out of convoy operations without the help of inexperienced boats is unavoidable.  We cannot alter the fact that the difficult school of convoy attack cannot be completed at home, but first of all when in direct contact with the enemy.
  b)  U 134 received orders to proceed via DM 52 to DN 70 and 80.
     U 132 was informed of convoy traffic south of Newfoundland and Nova Scotia.
  c) - d) None.

Appendix to 25th July 1942
       
Donitz here, how are weather conditions?  What speed can boats make on general course 2150?
       
Topp here, W.S.W. 8, sea 7, cyclones, visibility about 400, slow speed one engine.  122.
       
What was defense like?  In what other ways was attack on convoy difficult?
       
   Strong escort, attack was rendered more difficult by sudden blowing up of bad weather.  Convoy made most of this in alterations of course up to 3600.  This caused number of boats to lose contact.
       
What is your view on the likelihood of making further contact with convoy, separate single ships for instance?
       
Convoy keeping excellent station even in bad weather, consider possibility of regaining contact under these conditions, that is under the average bad weather conditions in this area, extremely small.
       
   Do you think the boat could proceed on southerly course, and if so would this course bring them nearer to conjectured position of convoy?
       
   Slightly more to the south;  presume convoy will alter course to the S.W. at dawn as on previous day.
       
Well done Topp, the weather at any rate will settle the account of your two steamers, good luck.
