2232 - Incoming F.T.: From B.d.U.:
At 1158 in BE 6520 U 528 (Oblt. Georg von Rabenau) requested immediate assistance from planes as she was totally unable to dive. She was ordered to move away to the west at once and report course and speed. U 558 (Kptlt. Günther Krech) was ordered to proceed to her assistance. Air support cannot be provided before 12.5. by a BV 128. No further messages have been received from U 528.

2304 - Incoming Radio Reports:
From OKW:
a) The British are evacuating Maungdaw before the Monsum season begins in Arakan.

From B.d.U.:
a) U 177 (IXD2; Kptlt. Robert Gysae) has been allocated the area between GR 54 and KY 66, and that north of JJ 48 as her attack area. When the moon is favourable, she is to operate close inshore and later move away to the south. Independent traffic is suspected inshore and in JJ 10-50. It remains to be seen whether the "Bachstelze" being tried out by this submarine proves its worth.
b) U 192 (Oblt. Werner Happe) is listed as missing 3 stars and U 663 (KrvKpt. Heinrich Schmid) has not been picked up although an escort has been sent out several times. She must be assumed lost.
B-Dienst Report:

2303 – Incoming Radio Reports:
From O.K.W.:
a) Japanese troops crossed the Yangtze River near Baiyang, Hunan Province, China and attacked Chinese positions on the opposite shore.
b) 105 survivors of the "San Marco" Italian Naval Infantry Regiment, were evacuated from La Galite Island by motored torpedo boats.
From B.d.U.:
a) U 178 (IXD2; KrvKpt. Wilhelm Dommes) has been allocated KY 60, 90 and KZ 40 and 70 as attack area. Focal point off Port Elizabeth.
b) U 528 (Oblt. Georg von Rabenau) did not report, despite repeated challenges. U 558 (Kptlt. Günther Krech), who had been detailed to render assistance; heard about 40 detonations (bombs) between 1220 and 1330 on 11.5. It must be assumed that U 528 was attacked a second time by planes and destroyed. Loss is probable.
B-Dienst-Report:
a) Just 17 months after the first conceptual meeting for an acoustic homing torpedo, the Mark 24 FIDO aerial torpedo had its first operational victory when a Liberator bomber of RAF Coastal Command’s 86 Squadron caught German submarine U-456 (Kptlt. Max-Martin Teichert) on the surface in the mid-Atlantic, while operating on convoy HX.237. As the submarine dove, the bomber dropped one Mark 24 torpedo that guided itself to the submerged submarine and exploded, causing major damage. Later that same day when U-456 was forced to dive deep to avoid a depth charge attack by destroyer HMS Opportune, the previous damage proved too great and the submarine sank with all 49 hands.
b) An enemy submarine situation report received on 11.5. gave several of our patrols or supply groups in the North Atlantic, and it is becoming increasingly clear, that the enemy has excellent radar gear capable of picking up the submarines without their knowing it. In the case of these known dispositions not enough radio messages were sent to provide the enemy with sufficient material for his deductions.
c) Auxiliary Aircraft Carrier USS Card (CVE-11) arrived in New York Harbor, anchoring off Tompkinsville, Staten Island.

First War Patrol
(17th war patrol overall)

Thursday, 13 May 1943 - East of the Azores

0310 - Qu.5855CF -

0630 - Early Morning Dawn.

0749 - Sunrise. Weather and Sea unchanged in 10h.

0819 - Qu.5877CF Center - "ALARM!" for Flying Boat, only medium speed. Was initially sighted at 0818 in 100°true, E=8800, on course NW. Turned towards the boat in 60°true and E=5800.

0822 - At A-Meter 1 Wabo and at 0823 another 2 Wabos - no damages.

Suspect the same airplane that was sighted on 11 May, at 1828, in Qu.6155CF.

0917 - At Reception Depth.

0919 - Surfaced after 1h and 2.8nm.

0920 - Boat ventilated.

0925 - Compressed Air Supply filled.

1032 - Qu.8133CF bottom left - FuMB-Detection (also, Magic Eye) and shortly after a Flying Boat sighted in 280°true, E=12000. Boat remains surfaced.

This seems to be again the same airplane as sighted at 0819h and on 11 May.

1107 - Qu.8135CF top right - FuMB-Detection in 330°true, E=15000 (no Magic Eye).

1108 - Diving for Flying Boat identified as Sunderland, in 335°true, E=10600, on course SE.

1110 - At Reception Depth no bombs.

1138 - Surfaced after 30min. and 1.5nm.

1139 - Boat ventilated.

1200 - Qu.8135CF - Days Run: 162.0nm - ↗ 148.7nm (19h 20') - ↘ 13.3nm (4h 40')
Total: 1658.6nm (8d 22h) - ↗ 1592.0nm (7d 22h 05') - ↘ 66.6nm (23h 55')
489cbm (2cbm in 24h); Course 227°; Battery 96%; Weather and Sea unchanged in 14h.
Note: Possible salvo shots with 3 torpedoes are: I-II-III and II-III-IV.

1550 - Qu.8155CF –

1736 - Qu.8157CF bottom left - FuMB-Detection in 145°true, E=14300 (also, Magic Eye). Shortly afterwards, appears "our" Sunderland again in 145°true, on course 306°, E=10900.

1737 - Diving for Sunderland. At T=20 no bombs.

1817 - Surfaced after 40min. and 1.9nm.

1818 - Qu.8173CF - Boat ventilated. Shortly after surfacing, the boat is attacked by the Sunderland from 250°true, is already very close. The airplane must have been equally surprised to see us, as we them, because the 3-4 Wabos fall wide to port. Sunderland flies off on course SE, machine gun fire from the tail turret. Boat remains surfaced.

Boat sustained 2% hull damage; total of 4% for this patrol (230m x 96% => 220.8m)

Cmdr.: This sea area is certainly highly patrolled by air - usually an indicator for high value shipping traffic.

2155 - Sundown. Weather and Sea unchanged in 24h.

2304 – Incoming Radio Reports:
From O.K.W.:
a) At 1100, the Axis Forces in Tunisia, accepted the terms of unconditional surrender. Besides 130,000 German and 120,000 Italian troops, General von Arnim and 25 further Axis Generals have been taken prisoner of war.
b) The Royal Navy has begun with the bombardment of Pantelleria.
c) 26 B-24s of USAAF 44th Bomb Group launched from Benina Airfield in Libya at 0400 hours. 20 of them reached their target, the Wiener Neustadt Air Frame Works.
From O.K.M.:
a) Italian torpedo boats stationed at Yalta, Ukraine, conducted their last sortie from this base.
From B.d.U.:

First War Patrol
(17th war patrol overall)

Thursday, 13 May 1943 - East of the Azores

0310 - Qu.5855CF -

0630 - Early Morning Dawn.

0749 - Sunrise. Weather and Sea unchanged in 10h.

0819 - Qu.5877CF Center - "ALARM!" for Flying Boat, only medium speed. Was initially sighted at 0818 in 100°true, E=8800, on course NW. Turned towards the boat in 60°true and E=5800.

0822 - At A-Meter 1 Wabo and at 0823 another 2 Wabos - no damages.

Suspect the same airplane that was sighted on 11 May, at 1828, in Qu.6155CF.

0917 - At Reception Depth.

0919 - Surfaced after 1h and 2.8nm.

0920 - Boat ventilated.

0925 - Compressed Air Supply filled.

1032 - Qu.8133CF bottom left - FuMB-Detection (also, Magic Eye) and shortly after a Flying Boat sighted in 280°true, E=12000. Boat remains surfaced.

This seems to be again the same airplane as sighted at 0819h and on 11 May.

1107 - Qu.8135CF top right - FuMB-Detection in 330°true, E=15000 (no Magic Eye).

1108 - Diving for Flying Boat identified as Sunderland, in 335°true, E=10600, on course SE.

1110 - At Reception Depth no bombs.

1138 - Surfaced after 30min. and 1.5nm.

1139 - Boat ventilated.

1200 - Qu.8135CF - Days Run: 162.0nm - ↗ 148.7nm (19h 20') - ↘ 13.3nm (4h 40')
Total: 1658.6nm (8d 22h) - ↗ 1592.0nm (7d 22h 05') - ↘ 66.6nm (23h 55')
489cbm (2cbm in 24h); Course 227°; Battery 96%; Weather and Sea unchanged in 14h.
Note: Possible salvo shots with 3 torpedoes are: I-II-III and II-III-IV.

1550 - Qu.8155CF –

1736 - Qu.8157CF bottom left - FuMB-Detection in 145°true, E=14300 (also, Magic Eye). Shortly afterwards, appears "our" Sunderland again in 145°true, on course 306°, E=10900.

1737 - Diving for Sunderland. At T=20 no bombs.

1817 - Surfaced after 40min. and 1.9nm.

1818 - Qu.8173CF - Boat ventilated. Shortly after surfacing, the boat is attacked by the Sunderland from 250°true, is already very close. The airplane must have been equally surprised to see us, as we them, because the 3-4 Wabos fall wide to port. Sunderland flies off on course SE, machine gun fire from the tail turret. Boat remains surfaced.

Boat sustained 2% hull damage; total of 4% for this patrol (230m x 96% => 220.8m)

Cmdr.: This sea area is certainly highly patrolled by air - usually an indicator for high value shipping traffic.

2155 - Sundown. Weather and Sea unchanged in 24h.

2304 – Incoming Radio Reports:
From O.K.W.:
a) At 1100, the Axis Forces in Tunisia, accepted the terms of unconditional surrender. Besides 130,000 German and 120,000 Italian troops, General von Arnim and 25 further Axis Generals have been taken prisoner of war.
b) The Royal Navy has begun with the bombardment of Pantelleria.
c) 26 B-24s of USAAF 44th Bomb Group launched from Benina Airfield in Libya at 0400 hours. 20 of them reached their target, the Wiener Neustadt Air Frame Works.
From O.K.M.:
a) Italian torpedo boats stationed at Yalta, Ukraine, conducted their last sortie from this base.
From B.d.U.:
a) U 180 (IXD1; Fregkpt. Werner Musenberg) Situation report: From 4-7 May stalked E-W traffic off Durban but found nothing. No traffic in KP 39 either. Destroyer and corvette in KP 9123, course 220°. Probably shot down a Handley Page on 12.5. in KZ 4155. Coastwise traffic off Cape St. Lucia according to bearings obtained.
b) U 217 (VIID; Kptlt. Kurt Reichenbach-Klinke) reported that she had carried out minelaying task. Mines were laid in AM 8926 and 28.
c) U 218 (VIID; Kptlt. Richard Becker) met Milkcow U 461 (Kptlt. Wolf-Harro Stiebler) to get medical attention for a sick man with a broken leg, who was subsequently transferred to U 461.

Reached first patrol point acc. Op.-Orders, on 12 May, 0900.
On 13 May, 0819, Sunderalnd in Qu.8133CF bottom left, and at 1108 in Qu.8135CF top right, and again at 1736 in Qu.8157CF bottom left. On 13 May, 1817, in Qu.8173CF top right, shortly after surfacing attacked by Sunderland with Wabos and Gun Fire, minor damages. Suspect the same airplane each time. Continue outbound transit. 488cbm. S7/6, clear, visibility 6.5nm, >1000mb. - RST -

0353 - Qu.7655CF -

0700 - Early Morning Dawn.

0810 - Sunrise. Weather and Sea unchanged in 1 day and 10h.

1036 - Incoming F.T.1030/14/5: From B.d.U.:
B-Dienst reports enemy convoy in Qu.1287DH, on course NNE, speed 6kn.

Cmdr.: As suspected, the strong enemy air patrol indicated that there must be a convoy or other high value shipping passing through this area.

1045 - Boat is operating on the convoy. Course 139°, 2xH.F.
Estimated contact with convoy at 1730 in Qu.1229DH.

1200 - Qu.7917CF - Days Run: 189.0nm - ↗ 187.1nm (23h 20') - ↘ 1.9nm (40')
Total: 1847.6nm (9tg 22h) - ↗ 1779.1nm (8tg 21h 25') - ↘ 68.5nm (1tg 00h 35')
487cbm (2cbm in 24h); Course 140°; Battery 96%; Bold 9 each; Weather and Sea unchanged in 1 day and 14h.
Note: Possible salvo shots with 3 torpedoes are: I-II-III and II-III-IV.

1608 - Qu.7989DH center left - "ALARM!" for Sunderland in 115°true, on course WNW, E=10500.

1611 - At A-Meter no bombs.

1618 - Course 90°, 1/3-Ahead.

1637 - At Reception Depth.

1643 - Surfaced after 35min. and 2.0nm.

1644 - Sunderland can be seen flying off in 35°true, on course ESE, E=6000. Boat remains surfaced.

1646 - Boat ventilated and Compressed Air Supply filled.

1651 - Course 115°, 1/3-Ahead.

1834 - Qu.1226DH - FuMB-Detection twice in relative bearing 118° (no Magic Eye).

1837 - (Battle Class) Destroyer bearing 57°, E=14000, on course 31°, slow speed.

Cmdr.: After diving for the Sunderland, we almost missed the contact point with the convoy but found it now as calculated. Historically, Battle Class destroyers didn't see any action in WWII.

1845 - Boat is positioned toward the front of the port side of the convoy, which slowly comes into sight. Going on parallel course 31°. Convoy speed is determined as 6-7kn.

1855 - Outgoing F.T.: To B.d.U.:
"Gustav Gelb!" Sighted convoy 1030/14/5 in Qu.1229DH top right, course 31°, speed 6.5kn. Keeping contact with Battle Class Destroyer. S7/6, medium heavy swell, clear, visibility 7.5nm, >1000mb. - RST -

1858 - Incoming F.T.: From B.d.U.:
RST: Assume attack position and keep contact with convoy. Await further orders but if situation allows you are free to attack.

Shortly after sending the F.T., the (Battle Class) Destroyer goes on a search pattern and a second escort comes into sight. Boat has to keep distance to escorts by changing speed and course, E=11100.

2148 - A Sunderland crosses our stern at a distance of 6400m on course WNW, goes out of sight at E=12000.

All the while, the (Battle Class) Destroyer must smell that something is up, because she continuously goes on search patterns, while the other escort stoically stays its course.

Cmdr.: I decide to dive for a submerged attack while it is still dusk and before the Sunderland comes back around.

2200 - Qu.8748CF - Diving for submerged attack, at E=11000, T=18.

2205 - Course 121°, which will be the attack course.

2211 - Sundown.

2222 - At E=4000 to Destroyer, rigging for Silent Running.

According to the sound contact, the storm must have divided the convoy into two parts, a faster section of 10 steamers in front and a slower section of 11 steamers behind. All in all, 9 escorts are heard.

2245 - The boat passes in between the forward port leading escort and the forward port side escort. No ASDIC is heard. Secured from Silent Running, 1/3-Ahead.

2258 - S-Tiefe. "Battle Stations!"

2301 - Qu.8749CF - Submerged Spread Shot with tubes I-II: T-3/Pi39H (MZ); Angle of divergence 1.5°; Running depth 4m; Vt30; Own course 121°; Own speed 4kn ahead; Target ship: Row Carrier 5761ts, draught 5.8m.
Target course 31°; Target distance 500m; Target angle red90°; Target speed 10kn; Firing angle α 353°.

Shooter: KvtKpt. & Cmdr. RST.

Both torpedoes are hits, No.1 midships, No.2 in the aft section!

The steamer explodes in a huge fireball which can be heard and felt in the whole boat, and sinks burning over its entire length within 2 minutes. Must have been loaded with some very hazardous cargo.

We have to withdraw backwards as to not endanger the boat from the explosions and also, not to get rammed by a HogIsland Freighter, that is evading the torpedoed Row Carrier towards our position.

2306 - Qu.8749CF - Submerged Single Shot with tube IV: T-3/Pi39H (MZ); Running depth 4m; Vt30; Own course 121°; Own speed 5kn ahead; Target ship: Liberty Cargo 5681ts, draught 5.8m.
Target course 31°; Target distance 1500m; Target angle red90°; Target speed 10kn; Firing angle α 314°.

Target course 31°; Target distance 1500m; Target angle red90°; Target speed 10kn; Firing angle α 304°.
Weather/Sea: S7/6, medium heavy swell, clear, visibility 6.5nm, >1000mb.
Shooter: KvtKpt. & Cmdr. RST.

Right after the shot, turning boat hard to stbd., to bring the T-4 to bear.

2309 - Flooding tube VI. The AtoFat (Tube III) is a hit but fails to detonate - suspect too sharp of an angle for the contact fuse.

2311 - Qu.8749CF - Submerged Single Shot with tube VI: T-4 "Falke"/Pi39H (MZ); Running depth 4m; Vt20; Own course 175°; Own speed 3kn ahead; Target ship: Liberty Cargo 5681ts, draught 5.8m.
Target course 31°; Target distance 1500m; Target angle red160°; Target speed 10kn; Firing angle α 138°.
Weather/Sea: S7/6, medium heavy swell, clear, visibility 6.5nm, >1000mb.
Shooter: KvtKpt. & Cmdr. RST.

2312 - Tube IV (T-3), that was a miss on the Liberty Cargo, is a hit on another unidentified vessel, after 6 min., so, almost at the end of its run time.

2317 - Sound Operator reports sinking sounds from the direction of the tube III torpedo impact.

2319 - The T-4 "Falke" is a hit after 8 min. Assuming hit on the Liberty Cargo.

A Black Swan Sloop and a C&D Destroyer are circling around our shooting position.

2325 - Flooding tube V.

2326 - Qu.8749CF - Submerged Single Shot with tube V: EtoFat/Pi39H (MZ); Running depth 4m; Vt30; FAT-Settings: Straight Run 2000m - Giro Angle green90° - Giro Run 1600m; Own course 210°; Own speed 3kn ahead; Target ship: Black Swan Frigate 1250ts, draught 3.7m.
Target course 265°; Target distance 1500m; Target angle red80°; Target speed 10kn; Firing angle α 284°.
Weather/Sea: S7/6, medium heavy swell, clear, visibility 6.5nm, >1000mb.
Shooter: KvtKpt. & Cmdr. RST.

After the shot, the Sloop is turning away on a northerly heading, while the C&D-Destroyer is shooting star shells and searching for survivors.

The EtoFat is a miss after the end of the run.

2330 - "Dismissed from Battle Stations!".

A Diana Typ Steamer 2600ts, loaded with tanks on the upper deck, is passing our port beam on course 31°, slow speed.

c) U 186 (KrvKpt. Siegfried Hesemann) was directed to attack Convoy No. 39. She last reported on 12.5. from CE 2244: "intend to attack reported enemy forces". The boat was probably destroyed during this daylight attack. She is presumed lost.
d) U 89 (KrvKpt. Dietrich Lohmann) stalked Convoy No. 38 and on 12.5. sighted smoke plume and carrier borne plane in BD 6921. Since that time boat has not reported again despite challenge. She must be presumed lost - probably through air attack.

B-Dienst-Report:
a) According to a special Radio Intercept intelligence report the convoy "HX 238" was in BC 4851 at 2000 on 12.5. From that position she steered a course of 48° to BC 4338 and from that position was to change her course to 350°.
b) Auxiliary Aircraft Carrier USS Card (CVE-11) departed New York bound for Casablanca, Morocco ferrying aircraft and troops.
c) Auxiliary Aircraft Carrier USS Bogue (CVE-9) transfered from Belfast to the Firth of Clyde, Scotland for calibration of her HF/DF radio detection gear.
d) In Britain, following more "Upkeep" bomb dropping training at the Wainfleet Bombing Range on the Wash (where a wooden mock up of the dam's towers had been constructed) at full night dress rehearsal was conducted on the Uppingham and Colchester reservoirs.
e) British Mosquito reconnaissance aircraft photographed a German rocket at Peenemünde, Germany; it was estimated to be 38 feet in length and 2 feet in diameter.

To all Submarine Commanders:

In his efforts to rob the submarines of her most valuable characteristic (invisibility) the enemy is several lengths ahead of us by virtue of his radar location.
I am fully aware of the difficult position that this puts you in when fighting enemy escorts and anti-submarine forces.
You may rest assured that I have done, and shall continue to do everything within my powers as Commander-in-Chief to change this situation as rapidly as possible.
Work is being carried on both within the Navy and outside it to develop and improve your weapons and gear.
I expect you to continue your determined struggle with the enemy and by pitting your ingenuity, ability and toughness against his tricks and technical developments, finally to finish him off.
Commanders in the Mediterranean and Atlantic have proved that even today the enemy has weak spots everywhere and that in many cases the enemy resources are not nearly so efficient as they would appear at first sight, if the boat's Commander is determined to score a success in spite of everything.
I believe that I shall shortly be able to give you better weapons for this hard struggle of yours.

1844 - Incoming Radio Reports:

O.K.W.-Report:
a) Japanese troops surrounded Chinese troops near Baiyang, Hunan Province, China, inflicting heavy casualties.
b) Luftwaffe I./KG 55, flying He 111 bombers, departed from Sarabuz Russkiy Airfield in Krym, Russia for Stalino (now Donetsk), Ukraine. The transfer was in response to the Soviet counter-offensive toward Kharkov, Ukraine.

O.K.M.-Report:
a) British Admiral Andrew Cunningham announced that "the passage through the Mediterranean was clear", and convoys from Gibraltar to Alexandria, Egypt resumed.
b) During convoy action from 9-13 May against convoys HX.237 and SC.129, in favorable attack conditions, very strong and accurate defense and radar activity. Only 5 ships sunk and 3 own losses.

B.d.U-Report:
a) U 266 (Kptlt. Ralf von Jessen) and U 753 (FrgKpt. Alfred Manhardt von Mannstein), have been lost with all hands.
b) U 108 (Kptlt. Ralf-Reimar Wolfram; ex KrvtKpt. Klaus Scholtz) has been withdrawn from active service and will be used as a school boat.

B-Dienst Report:

At the time the Groups "Isar", "Inn" and "Lech" totaling 13 boats were lying in the area named. As only one radio message was sent from this area on 11.5, it appears that only location can have been used as a basis for this report.
At the same time about 10 boats were supposed to be in the area between 50-55° North and 27-30° West. However, at the time, only 2 tankers and one submarine were there. During the previous days several radio messages were sent.
b) Auxiliary Aircraft Carrier USS Bogue (CVE-9) returned to Belfast, Northern Ireland from the Firth of Clyde, Scotland for 16 hours before departing again bound for Iceland.

b) Auxiliary Aircraft Carrier USS Bogue (CVE-9) returned to Belfast, Northern Ireland from the Firth of Clyde, Scotland for 16 hours before departing again bound for Iceland.

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.
