First War Patrol
(17th war patrol overall)

Sunday, 9 May 1943 - West of Vigo

- continued from 9 May 1943, 1215 -

1657 - Qu.1755CG top right - Diving for FuMB Detection (No Magic Eye) in 210°true, E=13000.

1700 - At T=30, one bomb at the diving position and again at 1701.

1703 - At A-Meter, no sound contact.

1723 - At A-20, Sound contact warship bearing 328°, E=14000, on course NW. Seems to be too far from the position of the last contact at noon, to be the same escort group.

1729 - Reception Depth.

1737 - S-Tiefe. U Class Destroyer bearing 330° on search pattern, E=7500. Anything further cannot be seen due to the high swell and the destroyer is too close to be able to surface.

1741 - Boat turning to course 321°.

1748 - The destroyer runs off at high sped on course West.

1757 - Surfaced after 1h and 3.1nm.
Escort Carrier sighted bearing 323°, on course 323°. Boat changing course to 304° and A.K.

1815 - Qu.1752CG bottom left - Boat is attacked by carrier-based A/C with machine guns and bombs, E=2500. Turing toward the approaching A/C hard to port, which cause the two bombs to overshoot the boat. After the fly-over, "ALARM!".

1817 - At T=25, ejecting one Bold (9 pcs. left), and running off on course 004°.

1818 - At A-Meter no further bombs or damages, but two destroyers are approaching our diving position.

1821 - At E=7000 to destroyers, rigging for Silent Running. The Escort Carrier seems to have reduced its speed, most likely zig-zagging.

1832 - The two destroyers run off from our diving position, in direction toward the Escort Carrier. As before, one very fast and the other at medium speed.

1842 - At Reception Depth. Secured from Silent Running.

1845 - S-Tiefe. A G&H Destroyer bearing 225°, E=6500, still on search pattern.

1855 - In the B-Periscope a carrier based A/C is seen on our stbd. beam, approaching from NNE, on opposite course, and dropping two bombs in the area of our last diving position, 4250m astern.

1910 - At E=10000, the Destroyer is out of sight (a faint smoke trail can still be seen in the B-Periscope).

1915 - Surfaced after 1h and 3.1nm.

1918 - Qu.1752CG top left - Right after the boat is ventilated and the Compressed Air Supply is filled, the boat is attacked by an Avenger A/C with Machine Guns, bombs and RP-3 Rockets, direct approach from West. Again, turned toward the approaching A/C with A.K., which cause the bombs and rockets to overshoot the boat. Right after the fly-over, "ALARM!".

1921 - At A-Meter, rigged for Silent Running and ran-off on course 0°.

1930 - As the two destroyers about 13000m away are not approaching, secured from silent running.

1940 - A-20.

2015 - After the watch change, set for Reception Depth.

2028 - Surfaced from S-Tiefe after 1h 10min. and 3.1nm.

2033 - Boat ventilated. On course 65°.

2037 - Compressed Air Supply filled.

2040 - Charging batteries (80%): Stbd.Diesel, Charging/496RPM; Port.-Diesel, Propulsion/285RPM/8kn. FuMB-Detection in 250°true, E=14500 (No Magic Eye). Boat stays surfaced.

2108 - Sundown. Weather and Sea unchanged in 38h.

2220 - Batteries charged: 1h 40min. for 20%.

Sunday, 9 May 1943 - West of Vigo

- continued from 9 May 1943, 2220 -

2233 - Outgoing F.T.: To B.d.U.:
9.5., 0920, Qu.1577CG, Escort Group with Escort Carrier and three Destroyers and again at 1700 in Qu.1755CG, both on course NW, 18kn. Both times not able to attack due to attack of carrier based airplane and high swell at day time. No damages. Suspect two different escort groups. Switching to Circuit Amerika-I. 497cbm. 15 eels. ENE5/4, clear, visibility 7.5nm, >1000mb. - RST -

2304 - Incoming F.T.'s:
From O.K.W.:
a) The German occupation government in the Netherlands declared martial law.
b) The "San Marco" Italian naval infantry regiment surrendered at Bizerte, Tunisia.
From O.K.M.:
a) In order to make it possible for the boats to guide in other boats when they themselves have sighted a convoy even when there are major differences in fixes, a shadower's signal buoy has been constructed and two boats (U 358 and U 381) have been equipped with one to try out. The buoy is to be fired as a star or rocket in the same way as the former signal rocket with axial staff, and will be distinguishable by very obvious characteristics from star signals and illuminant rockets, as the enemy often uses these to lead our boats astray. If these buoys are satisfactory, it is intended to use them operationally.
From B.d.U.:
a) U 666 Oblt. Herbert Engel) brought down a "Halifax" (misidentified as a Sunderland) with 6 shots at 1028 in the Bay of Biscay, Qu. BE 6888. The Halifax only strafed the boat on its first attack and received AA hits in one of the port engines during a second run. The pilot then apparently lost control when turning to come in again and the Halifax crashed into the sea about 500m (546 yds) from the boat, killing the crew of eight.
b) U 648 (Oblt.d.R. Peter Arthur Stahl), 168, 381 and 226 refueled from U 459 (KrvKpt. Georg von Wilamowitz-Möllendorf).
c) U 663 (KrvKpt. Heinrich Schmid) was not found and so far, has not reported. According to dead reckoning she must enter port at the latest on 12.5.
d) U 531 and 438 were probably caught unawares and sunk in the thick fog while operating on convoy No.36, U 438 was probably lost after a daylight attack. U 630 and U 192 (Oblt. Werner Happe) did not report at all after attacking the convoy. Last message from U 630 was dated 21.4. as she left the supply boat in BD 25. U 192 last radioed on 3.5. from AJ 3757 (Convoy No. 33). Both these boats may therefore have been lost earlier.
5 boats must be considered lost.

b) Winston Churchill arrived in Washington DC for the Trident Conference scheduled to start tomorrow.
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.

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.

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')

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.

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.

"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.

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.
