III. Reports on the Enemy:
  a) 1) U 572 reports a freighter of 5,000 BRT sunk in CA 8915 on 16.4 and freighter of 10,000 BRT in DC 3248 on 20.4.
    2) U 654 sank a large American freighter of 7,000 BRT in DC 26 on 20.4.  General course 1000.
    3) U 109 sank an ammunition freighter of 7,000 BRT in DC 3233 on 20.4.  General course 1000.
    4) U 575 sank a freighter type "Baron Inchape" (7,005 BRT) in CB 44 on 16.4.
    5) U 136 torpedoes a freighter or tanker of 6,000 BRT in CA 79 on 19.4 large fire, total loss probable.
    6) U 130 situation:  Bombarded oil depot in Bullen Bay on Curacao in the morning of 19.4.  Some visible results.  Rapid defense from shore.  Settlement very well camouflaged.  
      Sunk:  11.4 DP 5418 "Grenanger" (5,393 BRT), course 3300.  12.4 DP 4754 "Esso Boston" (7,699 BRT), course 3400.  No traffic from Anegada to Curacao.
  b)  None.
  c)  SSS in CA 7656 - EC 9624 - CA 3756 - DN 1247; further in EC 96 - DB 56.  "Brittannia" (9,967 BRT) in DB 5932.
  d)  None.
       
IV. Current Operations:
  a) - b) None.
  c) In area BE 3 boats (U 82 - 587 - 252) have been lost during the last three weeks while attacking south-bound convoys.  During the same period heavily escorted convoys in the area AM and AL have been successfully attacked by single boats, and losses have only occurred at convoys sighted in BE.  It is suspected that the English sail especially well-escorted convoys, perhaps even a kind of U-boat decoy convoy, along the routes which he knows to be used by U-boats on their way out and back.
             Boats are therefore ordered not to attack when they sight a convoy in BE, but to move off and then report.  It is wrong to risk boats in side operations where chances of success are doubtful, when at the same time the favorable conditions of the American area give great chances of success at less risk.

III. Reports on the Enemy:
  a) 1) U 126 reported a convoy at 1915 in BE 76, course 200.  8 steamers and 3 destroyers distinguished.  Moved off as ordered.  At 0145 the same boat sighted a convoy in BE 78, 4 vessels making heavy smoke, course northeast.  The former convoy may possibly be identical with SL 107 (though nevertheless there are remarkably few vessels), but the second cannot be identified on the schedule known the suspicion, already mentioned, that special anti-S/M convoys are being sailed in area BE, is further confirmed by these reports.
    2) U 576 reported a convoy in CA 3354, 10 steamers, course 2700, she probably scored 4 hits.  Boat suspects supply traffic to Boston proceeds via CB 14 - 11 - 12 and CA 33.  Boat intends to operate in BC 10.  30.4 sank freighter of 5,000 BRT in CA 33.

    2) U 437 has been ordered to escort S.S. "Munsterland" home.  Rendezvous 9.5 CD 3670.
  d)  None.
       
V. Reports of Success:
  U 576 - 1 ship - 5,000 BRT sunk.
       
VI. General:
  1) Situation in the American Area:
            When sinking declines after 21 April, this at first gave the impression that traffic conditions on the American coast had
 
 
 
- 39 -
     
     

 

     
     
 
  changed and that the constant stream of independently-routed ships and ships in convoy had ceased.  This impression was confirmed by the decline in the numbers of SSS and attack reports received from the Radio Intelligence Service. But during the last days more frequent reports form boats, which had lain right under the coast despite bright full-moon nights, have shown this view to be false.
            As last month, the decline in sinking figures is attributable to unfavorable conditions for attack during full-moon and high pressure weather.  Boats cannot operate on the traffic routes right under land because they are constantly forced under water by the numerous sea and air patrols and have no chance to operate on the surface and charge their batteries.
            The U-boats fighting superiority over the anti-S/M defenses, which has so far always been proved, cannot be exploited in moon and weather conditions such as this.
            Verbal reports from returned C.O.'s gives the same picture again and again.
            Attacking conditions in the American area continue to be very good.  Anti-S/M activity has increased, but its fighting power, its concentration, its determination to attack and destroy are small.  "Those who fight are not sailors, but people who are being paid for their presence in the area endangered by U-boats."  C.O.'s are all of the same opinion, namely that the American area will remain a highly favorable area for attacks for some months to come and that a high percentage of successes can be scored with very few losses.
            In order to decide whether the battle in the remote American operations area, with the long passages there and back, is still worthwhile (even with total number of successes rising), it is necessary to compare the sinkings per boat per day at sea.
            This gives the following result:
     
Sunk per boat per day at sea in January 1942 209 BRT
  February 378 BRT
  March 409 BRT
  April 412 BRT
            This shows that, in spite of the increased anti-S/M activity and America's greater concentration on the U-boat war, the boat's successes have risen.  Their operation in the American area is therefore further indicated.
    2)  The present large number of boats which are in full fighting trim as far as fuel goes (6 type IXc and 11 fully supplied type VII c) permits the whole coastal area from Cape Sable to Cape West, the Gulf of Mexico and the Caribbean to be occupied.  The enemy will find it impossible to avoid the U-boats by re-routing his traffic.  These boats will reach their operations areas at the most favorable time, on May 8, one week before new moon.
    3)  Supplying from the first U-tanker has gone off excellently.  Altogether 10 boats have supplied on the way out, 2 on the way back, all in 10 days weather conditions admittedly being good.  The value of these supply operations can only be completely assessed when all the boats have completed patrols.

  Mine Situation in Biscay:
  I. The charts captured in Nazaire in the English destroyer Campbelltown, with the mined areas entered, confirm the necessity of abandoning the approach routes to Brest (Sternbild and Rippenbruch).  This had been done some time before.  The arrangement of the minefields also gives rise to the suspicion that the enemy had begun to cut off the Biscay methodically, starting from the north, by minefields along the 200 meter line.  As the northern approach routes to Lorient (Jugend Liebe and Bogenlampe) had been closed owing to enemy mines laid closer to the coast, the Brest boats had:
    1) to use the south route to Lorient (Cedernland) and then proceed along the coast on route Rosa, i.e. cover a longer distance through inshore waters endangered by mines and S/M's and
    2) to put into Lorient as an intermediate port, so that the additional danger from a/c was eliminated.  During daylight they lay in Lorient and continued their passage to Brest during darkness.  The consequent loss of half a day, outward and inward bound, had to be accepted.
  II. All U-boat traffic was now crowded onto the 2 routes Tannennadol and Uhunest, which lie close together and lead to the center of the Biscay coast, as the routes south of these, leading to Pallice and to the Gironde could not be constantly checked for mines, owing to F.O.I.C. Western Defenses' lack of forces, and were therefore closed.  This restriction to 2 routes means:
    1) A longer passage in inshore waters for all boats which belong to Brest, Pallice and Bordeaux.
    2) Crowding together makes things easer for enemy S/M's and a/c and raises the effectiveness of mining operations there.
    3) The basic principle, to allow only incoming or only outgoing U-boats or only minesweepers along one route at night, has in some cases to be disregarded, which means danger for the U-boats.
    4) If the principle in para. 3) is adhered to, which is essential on dark nights, then F.O.I.C. Western Defenses' few forces are further restricted in their movements, to the disadvantage of the safety of the U-boats.
    5) There is danger that the enemy will lay minefields in inshore waters which are not checked by us without our noticing it.  It is only a short step from there to closing the comparatively narrow checked emergency route in the center and Biscay suddenly being really cut off.
  III.  On 20 April route Burggraf was declared in use, and this meant a certain relief of the 2 central routes, as the italian boats were now given a direct route and Pallice boats could be escorted along this.  They still had to go out of their way slightly compared with the original direct approach route to Pallice
    This relief, which was comparatively slight, was more than cancelled out on 26.4 by the closing of route Tannennadel, which included Cedernland almost all the Atlantic boats, i.e. Brest, Lorient, and Nazaire boats, were now directed to route Uhanenst,
 
 
 
- 41 -
     
     

 

     
     
 
    which, apart from anything else, is a long way round to Brest and Lorient.  This intolerable state of affairs was considerably eased on 30.4 when route Bogenlampe came into use.
  IV. Present Situation:
    1) There are direct approach routes to: Lorient, Nazaire, Bordeaux.  Boats which are arriving at or leaving Brest go to Lorient as hitherto and leave there on the evening of the day they arrived.  Pallice boats have to be escorted either via Burggraf, 25 sea miles out of their way, or via Uhunest, 50 sea miles out of their way.
    2) Because of the few approach routes traffic along them is very dense, encounters cannot always be avoided.  If one of those routes, which lie far apart, comes into disuse it will mean a very long way around for some of the boats.
    3) F.O.I.C. Western Defenses' forces are at present just adequate to check the 3 routes.  They are not sufficient to clear the minefields already known, nor to search over other routes which may be free of mines, nor to clear the existing routes if these should be closed or fouled by the enemy.  This means that any minelaying by the enemy, which is most likely, would cause a very serious situation in U-boat traffic in inshore waters.
    This lack of forces is the reason why already now U-boats are in many cases forced to remain in inshore waters for a disproportionate length of time, instead of being able to cover this dangerous zone as quickly as possible, at right angles to the coast.  It thus endangers the whole offensive conduct of the U-boat war and can gradually stop it altogether unless assistance is provided.
  V. Attention has again been called to the intolerable state of affairs described above, by telephone from B.d.U. to Naval War Staff and by T/P from Group West.

          One of the reasons which led to the U-boats' no longer being operated methodically against convoys, is the fact that it was and is hardly possible to find the convoys with our inadequate means.  When a convoy has been found in my opinion the (one word illegible) should be realized, or it should be decided only from case to case, but not in principle to break off operations.
          Convoy escort is mostly likely to be very strong in BE because this is near to the Mother country and to Gibraltar, and will force breaking-off the attack early on, especially in the case of north-bound convoys.  But we are surely agreed that the sinking of a steamer near English ports is of great importance.  So the expression "side" operation for an attack on a convoy in BE is, in my opinion, ill chosen.

          As long as there is any suspicion that anti-S/M convoys may be expected in BE it is undoubtedly right to avoid attacking convoys in this sea area.  I also regard the expression "side operation" as wrong.

(MS note): Nevertheless the expression is open to criticism.

  1) The designation of such attacks as "Side operations" is in my opinion to be interpreted in the sense that in area BE they have no actual connection with the present main U-boat operations (American coast).
       
    2) The greatest difficulty undoubtedly lies in finding the convoys.  When a convoy has been found, an attack is in my opinion worth while, if several boats can be operated at the same time.

(MS note):  The order that single U-boats are not to attack such strongly escorted convoys cannot be questioned, the more so as it is suspected that they are "U-boat decoy" convoys.

The convoys encountered in BE are known from experience to be strongly escorted and are only found by chance by U-boats on their way out or way home.  So, as long as several boats cannot attack simultaneously, the damage to be expected must be greater than the possible advantages to be gained.  For this reason B.d.U. has ordered all further pursuit of such convoys to be abandoned.  Our experience of these convoys has, in my opinion, proved this order to be right.  Lately we have lost several boats operating singly against such convoys, without the smallest success, even though they went to it with a will.
