+++++++ U 115 - KTB - First War Patrol (17th war patrol overall) Monday, 19 April 1943 - 12th U.-Flotilla Bordeaux (Korvkpt. Klaus Scholtz; ex U 108) - Daily F.d.U. Briefing O.K.W.-Report: a) In Hamburg, Traute Lafrenz was sentenced to a one-year prison term for her involvement with the White Rose resistance group. b) Waffen-SS used tanks and other heavy weapons to counter the uprising in the Jewish ghetto in Warsaw. B.d.U.-Report: a) The boats U 648 (Oblt.d.R. Peter Arthur Stahl) and U 209 (Kptlt. Heinrich Brodda) detailed for operations on U 732's (Oblt. Claus-Peter Carlsen) report, have received orders at 1129 per F.T.1046/19/103 to continue operations if conditions make surprise enemy attacks appear unlikely and success probable. Up to 1900 all boats including U 954 (Kptlt. Odo Loewe) which also went after the convoy, had broken off operations owing to air activity and unfavorable weather conditions. The operation is therefore broken off. At 2231 U 648 (Oblt.d.R. Peter Arthur Stahl) is ordered per F.T.2148/19/122, to occupy AK 34 as temporary attack area. b) U 217 (VIID; Kptlt. Kurt Reichenbach-Klinke) has put out on special duties (Minelaying off Lands End). c) U 175 (KrvKpt. Heinrich Bruns) put out of Nazaire on 10.4 and was detailed to operate on Convoy No. 27 (HX.233) immediately on leaving the Biscay area. The boat reported for the last time at 1057 on 17.4 with a short contact signal. Position at this time was about BE 46. As repeated requests have not been answered its loss must be presumed. The convoy was heavily escorted by air and surface forces. RST

+++++++ U 115 - KTB - First War Patrol (17th war patrol overall) Wednesday, 21 April 1943 - 12th U.-Flotilla Bordeaux (Korvkpt. Klaus Scholtz; ex U 108) - Daily F.d.U. Briefing O.K.W.-Report: a) New Zealand Maori troops capture Takrouna, Tunisia, while troops of the 48th Battalion of the British Royal Tank Regiment, capture Tiger I tank "131" near Medjez-el-Bab, Tunisia. B.d.U.-Report: a) Convoy No. 28: At 0600 on the morning of the 21st, U 306 (Northern section of Group "Meise") sighted a northeast-bound convoy in AJ 2771. The first message from the convoy was not received until 0930. The boats belonging to the Group "Meise" were detailed to operate on the convoy if they were not more favorably placed to attack the southwestward-bound convoy further to the E. U 306 (Kptlt. Claus von Trotha) continually reported contact with the convoy (at 1614 in AJ 2586, course 90°) up to 0200 in the morning, in AJ 2696. This boat sank a ship of the type "Sibajack" (12.000 GRT) at this time and lost contact. U 598 (Kptlt. Gottfried Holtorf) reported a convoy hydrophone bearing at 0100. Other boats did not come up. 2 boats reported flying boats with the convoy. Visibility deteriorated during the night and fog and snow drifts came with a N.N.E. wind strength 8. Up to now, 7 U-boats are operating on the convoy, U 306, 631, 108, 598, 134, 552 and 189. In addition, a group of 5 more boats in waiting positions further to the E, are detailed for this - U 378, 732, U 648 (Oblt.d.R. Peter Arthur Stahl), 209 and 934. Operations on the convoy continue: At 1800, U 648 (Oblt.d.R. Peter Arthur Stahl) is ordered per F.T. 1713/21/172, to operate at increased cruising speed on the "Trotha"-Convoy (HX.234) and by dead-reckoning, can make contact with the convoy in the morning of 23 April. According to the plot and convoy reckoning this should be the expected HX convoy No. 234. b) U 217 (VIID; Kptlt. Kurt Reichenbach-Klinke) receives freedom of movement in BE. The boat is to withdraw from this area in good time so that the special duty can be carried out when the moon is in a favorable quarter (Minelaying off Lands End). B-Dienst Report: a) An attempt was made to assassinate General Charles de Gaulle when the Wellington bomber flying him to Glasgow, Scotland, was sabotaged at RAF Hendon. The pilot detected the elevator controls had been cut just before take-off and aborted the flight. The incident is hushed up and blamed on our intelligence but de Gaulle will never fly by plane in Britain again. RST

+++++++ U 115 - KTB - First War Patrol (17th war patrol overall) Thursday, 22 April 1943 - 12th U.-Flotilla Bordeaux (Korvkpt. Klaus Scholtz; ex U 108) - Daily F.d.U. Briefing O.K.W.-Report: a) South African and British fighters intercepted an Italian air convoy off Tunisia, and claimed to have shot down 12 transport aircraft and 7 escorts. On the ground, the final Allied assault began against the remaining Axis forces in North Africa with armoured thrusts from Sidi Nsir, Medjez, and Pont du Fahs. Only at Enfidaville was there a halt. Resistance remained fierce, however, and was professionally handled by the Axis troops, allowing Luftwaffe units to be evacuated from the shrinking perimeter. B.d.U.-Report: a) Convoy No. 28 (HX.234): Weather conditions in the convoy area are reported as wind N.W. 5, visibility 10 seamiles on 22nd. Contact, which was broken off at 2000, was not reestablished during the day. Only 2 steamers on a course of 60, a destroyer and an aircraft were reported by U 413 (Kptlt. Gustav Poel) in the evening. U 306 (Kptlt. Claus von Trotha) resumed contact with the convoy, lost it again and then reported the convoy in AJ 3361 at 0800. This boat also reported aircraft with the convoy. At 2350, U 648 (Oblt.d.R. Peter Arthur Stahl) is ordered per F.T. 2345/22/117, if no further contact, occupy until 1400, assigned position in patrol line AJ 2526 to 2959. U-Stahl is running a highest speed to assigend position. U 134 (Oblt. Hans-Günther Brosin) began the return passage owing to heavy damage to engine, not caused by enemy activity. 18 boats are now operating on the convoy. B-Dienst Report: a) British Mosquito reconnaissance aircraft photographed on of our rockets at Peenemünde, but intelligence analysts can not be certain of the object photographed. RST

+++++++ U 115 - KTB - First War Patrol (17th war patrol overall) Friday, 23 April 1943 (Good Friday) - 12th U.-Flotilla Bordeaux (Korvkpt. Klaus Scholtz; ex U 108) - Daily F.d.U. Briefing O.K.W.-Report: a) Our 17.Armee abandoned the attempt to dislodge the Soviet bridgehead at Novorossisk in southern Russia. B.d.U.-Report: a) Convoy No. 28 (HX.234): Weather conditions in the convoy area were reported as wind W.N.W. 5, visibility 15 sea miles at 1700 on 23rd. A boat reported wind N.W. 2, seaway 1 at 0200. U 306 (Kptlt. Claus von Trotha) reported the convoy on the 23rd at 0247 per F.T.0212/22/119 in AJ 3377, on northerly course and at 0807 per ßß-Signal in AJ 3361, course 60°, speed 8kn. Contact was reported throughout the day in such an exemplary fashion that 11 more boats were able to approach during the day and night owing to the good messages, e.g., beacon locator signal at 0909 which is heard by U 648 (Oblt.d.R. Peter Arthur Stahl) in 350°true, being positoned south of the convoy. At 1210, U-Stahl sights smoke plumes of 3-5 steamers and 2 masts, apparently in keel-line in, in 18°true, AK 1513, the ßß-Signals sent by U-Stahl and again at 1350 are not heard by command. At 1633, U-Stahl sends ßß-Signal: Enemy position AK 1533, 105°, which is immediately acknowledged by command. At 1928, U-Stahl has to crash-dive from a 4-engine land based A/C and has to evade an escort, ejecting a Bold. At 2120, U-Stahl surfaces but has lost its forward position to the convoy. At 2230, the weather rapidly starts to deteriorate. At 2346 in AK 1379, U-Stahl is at "Battle Stations", as the Commander wants to attack using the approaching rain and hail squalls from the West as cover. On 24 April, 0010, U-Stahl dismisses from Battle Stations as the hail squall is over and the boat losses its cover by the clouds lifting again for a surface attack and the distance is too great for a submerged attack. As the convoy cannot be seen, U-Stahl dives at 0138 for a listening check and obtains a good contact in 330°true, and surfaces again at 0153. U 306 reported the convoy in AK 2443 at 0700 on the morning of the 24th. Various boats again lost contact. In spite of this 7 boats were in the convoy area in the night. Not until 1900 was the convoy escorted by aircraft. The Command found it difficult to form a clear picture of the surface defence as only a few boats reported depth charge attacks. 4 boats were attacked with depth charges, one sustained considerable damage. One boat was attacked by aerial bombs. The mass attack on the convoy did not have the desired results. U 306 sank a steamer of 7,000 GRT at 1500 in an underwater attack. U 954 (Kptlt. Odo Loewe) also scored a hit in a daylight attack on a large steamer at 1600. U 610 Kptlt. Walter Freiherr von Freyberg-Eisenberg-Allmendingen) scored a "FAT" hit at 0635 on the 24th. 15 boats are now operating on the convoy, as 3 boats are attacking the recently intercepted S.W.-bound convoy. B-Dienst Report: a) Auxiliary Aircraft Carrier USS Bogue (CVE-9) and her task group departed Argentia, Newfoundland, bound for mid-Atlantic rendezvous with eastbound Convoy HX-235. RST

+++++++ U 115 - KTB - First War Patrol (17th war patrol overall) Saturday, 24 April 1943 - 12th U.-Flotilla Bordeaux (Korvkpt. Klaus Scholtz; ex U 108) - Taking boat out of dry dock and putting on charging station. During the shipyard time in Bordeaux, the pressure hull, torpedo tube no.6 and the flak guns were repaired. Several crew members had to disembark and were replaced, due to injuries sustained in the air attacks during the outbound transit. Beginning of pre-war patrol preparation. +++++++ Daily F.d.U. Briefing O.K.W.-Report: a) In the Mediterranean Sea, British submarine HMS Sahib (P 212; Lieutenant J. H. Bromage) was scuttled and abandoned by her crew to avoid capture after being seriously damaged by the Italian torpedo boat Climene and Ju88 aircraft off Cape Milazzo. All her crew was saved except for one who was wounded and will die on 3 May 1943. Her loss will be officially announced by the Admiralty on 6 May 1943. O.K.M.-Report: a) U 180 (IXD1; Fregkpt. Werner Musenberg) reported: Met at 0620 on 23.4. Exchange has so far been impossible owing to weather conditions. Boat accompanying until improvement in weather. (U 180 and the Japanese U-boat I-29 were ordered to meet at 0600 on 23.4 in JA 2432. After execution of special duties - transfer of two Indian Nationalist agents, to be put ashore by I-29 at Sumatra - U 180 is to operate in the lower third of KP and KQ and the upper third of KZ and JA, with central point off Durban. E.W. traffic is presumed in the vicinity of this port). B.d.U.-Report: a) Convoy No. 28 (HX.234): At 0200, U 648 (Oblt.d.R. Peter Arthur Stahl) is back o Battle Stations but is kept at bay by convoy escorts and is attacked with escort surface weapons at 0315 and has to crash-dive at 0328 and turns toward the convoy. At 130m, U-Stahl receives the first Wabos and dives deeper to 140-150m, and is now positioned right under the convoy; ASDIC pings continue until 0600 in Qu.AK 2336. At 0625 U-Stahl surfaces and has to crash-dive 5 times due to airplanes until 1912 (at 1000 U-Stahl briefly sights the convoy in 46°true and a VIIC type boat 2nm abeam to port). At 1953, U-Stahl surfaces in Qu. AK 3354, Wind and Sea have increased and the boat can not go faster than 2xH.F., as the sea is continually washing over the Conning Tower. At 2300, U 267 (Kptlt. Otto Tinschert) reports contact in AK 3493, and again at 2330. At 2342, the wolfpack receives F.T. 2325/24/131 from HQ: To Trotha-Convoy: If during the night no attack opportunity, operate in such a way that by daybreak boat is positioned in front of the convoy. In spite of the fact that altogether 12 boats were operating on the convoy on the night of 24th, and that at dawn several boats were still in contact, this could not be maintained during the day. The reason for this was the appearance of strong air escort with the beginning of daylight. B-Dienst Report: a) In the Pacific, after repeated failures, Admiral Nimitz discontinues the use of magnetic pistols on torpedoes for his theater of operation. Submarines under General MacArthur's command, however, continue to use them. RST

12. Unterseebootsflottille - Bordeaux - Pre-War Patrol Preparation
Quote:
+++++++ U 115 - KTB - First War Patrol (17th war patrol overall) Sunday, 25 April 1943 - Bordeaux - (Easter Sunday) Pre-war patrol preparation: - Taking on of Fuel Oil (510cbm at 865kg/m³) and Lubricating Oil. +++++++ Daily F.d.U. Briefing O.K.M.-Report: a) U 119 (XB; Kptlt. Horst-Tessen von Kameke) has put out for special duties (Mining Op. Halifax). b) U 177 (IXD2; Kptlt. Robert Gysae) reported experiences with "Bachstelze". c) Italian submarine Leonardo da Vinci hit British tanker Doryssa, en route from Cape Town, to Abadan, Iran, with a torpedo in the Indian Ocean at 1726 hours. At 1845 hours, a second torpedo hit her. Shortly after, Leonardo da Vinci closed in and sank the tanker with gunfire. 53 were killed, and the 11 survivors were picked up by British whaler HMSAS Southern Barrier five days later. Having expended all torpedoes, Leonardo da Vinci began her journey back to Bordeaux. B.d.U.-Report: a) Convoy No. 28 (HX.234): At 0130, U 648 (Oblt.d.R. Peter Arthur Stahl) sends F.T.0128/25/138: Due to A/C positioned 60nm behind Trotha-Convoy. Due to weather max. speed 11kn. Question continue Op. At 0200, another boat reports wind N.N.E. 9, seaway 8, visibility 500 meters. At 0900, U-Stahl is diving for torpedo maintenance and at 1218, receives F.T.1050/25/151 from HQ: Break off Op., proceed to SW. At 1554, U-Stahl receives F.T.1249/25/153 from HQ: Group "Meise" in new order Junker, Mäder ..., proceed at cruisng speed to position in patrol line from AK 2386 to 0347. Slow NE convoy will pass the area of the patrol line tomorrow. At 1718, U-Stahl surfaces and is in AK 3451 at 2400h, wind and sea have subsided considerably. The main reason for the failure of the operation can be attributed to the extremely changeable visibility experienced during the night, and very unfavorable weather, hail, fog, rain, snow squalls. The convoy exploited this very cleverly for his zig zags. The enemy sailed in line ahead with about 10 ships, and destroyers or escort vessels were disposed in the gaps (later it is determined, that convoy HX.234 consisted of 46 ships and 21 escorts). The Commanders, for the most part inexperienced and fresh from home waters, were unable to cope with these conditions. Air activity was so intense on the 24th, that all boats were beaten off and lost the convoy. As intensified air activity is anticipated in the vicinity of Iceland on the 25th, the operations were broken off on the morning of that day. Altogether 2 ships of 19,500 GRT were sunk and 2 ships torpedoed. b) The loss of U 191 (Kptlt. Helmut Fiehn; Convoy No. 30/ON.178) and U 189 (KrvKpt. Hellmut Kurrer; Convoy No. 28/HX.234) must be presumed. The boats reported for the last time on 23.4 from AK 01 and AK 15 respectively. RST
