Cmdr.: Something is going on. Why all of these sudden and unexplainable sinkings of our boats?! It must have something to do with the B.d.U.-F.T. from 15 May 1317.

She fired 2 two fan torpedoes on 2 large vessels, together 12,000 GRT. Sinking hydrophoned but not observed owing to defence activity. Subsequently air patrol. Commanding Officer confirmed with certainty deterrent depth charges at the convoy 2 hours after attack.

2256 - Sundown. NNW7/6 medium swell, clear light haze, medium visibility, >1000mb.

2305 – Incoming Radio Reports:

From O.K.W.:
a) Japanese Forces launch an offensive along the Yangtze River, about 400km northeast of the Nationalists Capitol of Chungking.

From B.d.U.:
a) U 648 (Oblt.d.R. Peter-Arthur Stahl) while entering the Bay of Biscay shot down a Whitley at 1424h in BF 4543, after dropping four depth charges, none of which caused any damage. The crew of six were all killed.
b) U 198 (IXD2; Kpt.z.S. Werner Hartmann) was driven off during night attack on convoy, reported yesterday in KP 8541, by aircraft using searchlights. During the night aircraft were continuously located but none approached. During the day active sea and air reconnaissance up to 50 miles from the coast. U 178 (IXD2; KrvKpt. Wilhelm Dommes) was detected by two aircraft carrying lights. She suspected cooperation of air cover with convoy of U 198. (Unlikely, since positions were too far apart). U 195 (IXD1; KrvKpt. Heinz Buchholz) is to operate in the area S. of Madagascar. Passage thence making long legs, sweeps under the coast. The attention of boats in the Capetown area is drawn to the fact that in Lourwence Marques and other harbors ships are delayed owing to U-boat warning and therefore, heavy traffic is to be expected off the harbors at times.
c) U 182 (IXD2; Kptlt. Asmus Nicolai Clausen) has probably been lost - has been at sea for over 5 months. According to an intercepted message, a U-boat was bombed on the 15th May in DH 4365 by a British aircraft which scored two hits. According to dead reckoning, U 182 was in this position. She was asked for her position but did not report again after the attack. She must be considered lost.
d) U 214 (VIID; Oblt. Rupprecht Stock) has put out for minelaying operations off Dakar.

B-Dienst Report:
a) Auxiliary Aircraft Carrier USS Bogue (CVE-9) and her task group departed Iceland and joined the escort of Convoy ON-184.
b) At 0730 hours, a Spitfire aircraft of No. 542 Squadron RAF flew across the Ruhr region and photographed the extent of the damage from the Dambuster Raid.

Acc. O.K.M.-Report as per B.d.U. F.T.1104/23/5, after 14 boats had been lost in the Atlantic in February, in March 13 and in April 12, the extent of the losses in the Atlantic in May has already reached the figure of 31 boats lost up to the 22nd May, and 2 further ones have probably been lost in the operation against HX 239.
Losses, even heavy losses, must be borne when they are accompanied by corresponding sinkings. But, in May in the Atlantic, the sinking of about 10,000 GRT had to be paid for by loss of a boat, while not long ago there was loss only with the sinking of about 100,000 GRT. The losses in May have, therefore, reached an impossible height. For one, they were lost during convoy operations and for another, during passage of the Bay of Biscay. Under the current circumstances, it is impossible to continue with convoy operations.

0745 - Qu.7488EJ - Crash dive for training. T=10 after 41 Sec.

0800 - A-20.

Weather and Sea unchanged.

1005 - Boat ventilated and Compressed Air Supply filled. 2x225RPM/8kn.

1038 - Sunrise. Weather and Sea unchanged in 6.5h.

1104 - F.T. from B.d.U.: To all boats:

Orders were given on May 22nd as follows ("All Waves"):

(Message 1752):
The danger of being surprised by locating aircraft is very great, especially at night. The following orders are, therefore, given:
1) Procedure when approaching and returning from the Biscay area and approaching the area home North Atlantic as in Permanent Order No. 13.
2) Procedure in the operational area North Atlantic when cruising and stopping in position.
a) By night: One electric motor slow to half speed, other motor Diesel ready to start up. Boats ventilator switched off. Reason for this: To be able to confirm approaching aircraft by hydrophone. MG ready and manned.
b) By day: With higher cruising speed than before confirm that boat can be easily maneuvered and is able to dive.
c) If weather conditions are unfavorable by day and night proceed only underwater.
3) When contacting the enemy: Operations as before.

(Message 1769):
In almost every operation boats are seriously endangered by submerging in view of aircraft even when a safe depth cannot be reached before the bombs are released. It should be impressed on all Officers of the Watch that when the protective depth i.e. 80 to 100 m., can no longer be attained with certainty before bombs are released, i.e. always when the watch on the bridge is taken by surprise, it is best to remain surfaced and ward off the aircraft attack with Flak guns. We do not know how often loss has been caused by submerging too late. However, we do know that defense measures when surfaced have led to success in all cases reported.
Apart from this, the situation in the North Atlantic now forces a temporary shifting of operations to areas less endangered by aircraft. The following areas come into consideration: the Caribbean Sea, the area off Trinidad, the area off the Brazilian and West African coasts. It is, therefore, intended to operate primarily with VIIC boats in these areas, as far as permitted by the supply situation. If necessary, operational boats must also be sent in to supply other boats. With the boats at present in the North Atlantic, operations will be made against the traffic between USA and Gibraltar - as far as these boats are able to do this with their fuel. The North Atlantic cannot, however, be entirely denuded of boats. It is necessary, by means of single boats, to leave the enemy in ignorance as long as possible regarding alterations in tactics. For this operation in the North Atlantic boats are available now which cannot be sent elsewhere in view of their fuel supplies, and also boats coming from home waters for their first operations, which must be assigned the stay in the North Atlantic in spite of the difficult conditions. It is intended to attempt attacks on a convoy only under particularly favorable conditions, i.e. in the time of the new moon. The new moon period at the end of June is the first to come into consideration, since the boats at present in the North Atlantic are no longer operational enough. It will be necessary to assign several veteran boats for this as a support for the newer boats in the North Atlantic.
These decisions comprise a temporary deviation from the former principles for the conduct of U-boat warfare. This is necessary in order not to allow the U-boats to be beaten at a time when their weapons are inferior, by unnecessary losses while achieving very slight success. It is, however, clearly understood that the main operational area of U-boats is, as it always was, in the North Atlantic and that operations must be resumed there with every determination as soon as the U-boats are given the necessary weapons for this. Equipment with 2 cm., quadruples, which will begin as from June to an increasing degree will be the first step in this direction, equipment with Zaunkönig torpedoes (anti-destroyer) the second step, while improvement of location devices at the moment is still to be considered. It is, however, anticipated that after equipment with quadruples, i.e. from the Autumn, the battle of the North Atlantis will be completely resumed once more.
In the meantime it is essential that the morale of the men should not be affected by these temporary defensive measures, a task which requires full cooperation of the Commanding Officers, as well as the personal touch of the Commander in Chief of the Navy.
