Hello to all :D; more..................

War with Great Britain and France!

On October 31, 1939, U 31 entered port. She found no patrols at Loch Ewe. However, there is a net snag in the bay, in which the submersible was entangled for some time, as she did not see the flat buoys until it was too late. Inside was a hospital ship, but nothing else. As it did not seem possible to enter, the ship placed the mines in front of the entrance of the bay at the minimum safe distance. The position of the mines is excellent. Success seems certain, but it is doubtful that we will hear anything about it.

U 25 reported a convoy northwest of Finisterre. This is the second convoy reported in a few days in this area, quite close to the coast. This one was also sailing north. It is notable that all 4 convoys reported so far have headed north. Southbound traffic apparently stays further west. Unfortunately, the problem of torpedo failures is still far from being solved. U 25 reports 4 misses against a stopped ship, close range shots.

The instructions of the Torpedo Inspection were observed. Therefore, there is no longer any doubt that the Torpedo Inspectorate itself does not understand the matter. Torpedoes cannot currently be fired with non-contact firing units, as this has led to premature detonation. It depth setting has to be 2 meters less than the draft of the target. Its depth cannot be less than 3 meters, otherwise there may be surface runs in which especially the G7a engines may be damaged. Exact instructions to establish the safety range are given and followed. However, at least 30% of torpedoes are misses. Either they don't detonate at all or they detonate in the wrong place. There doesn't seem to be any point in giving the U-boats new instructions, as they never lead to the desired results. The commanding officers must be losing confidence in their torpedoes. In the end, the fighting spirit will suffer. The problem of torpedo failure is currently the most urgent of all problems in submarine warfare.

The German Naval Attaché in MADRID reports that the Spanish government is not willing for the time being to allow the supply of German naval units within its sovereign waters. The BdU will be informed of this.

BdU discussion in the WEST Group in the presence of the B.S.W. (Befehlshaber Sicherung West). Various issues of submarine warfare are discussed, including the prize law system.

Hello to all :D; more..................

War with Great Britain and France!

On November 1, 1939, B-Dienst reported extensive French aerial reconnaissance activity over the Bay of Biscay, during which several U-boat sightings were reported. The Naval Warfare General Staff released a compilation of ship losses of enemy and neutral countries accumulated to date. 93 ships totaling 383,569 GRT are assumed to have been sunk, another 33 ships totaling 130,070 GRT probably have been sunk. Together they make 126 ships with a total of 513,639 GRT. Of these, 56 ships are assigned to the submarine Branch with a total of 238,810 GRT and four as prey with 6,766 GRT.

The Naval Warfare General Staff informed the BdU that the U 25 could not be supplied off the Spanish coast, since Spain had recently had political difficulties. The supply could only be arranged in El Ferrol in case of extreme need. Dönitz decided not to send the submersible there, in order to have this possibility at hand for really urgent cases and expressed: I am not surprised by this development; I always considered this matter very uncertain.

The OKM receives more details from the OKW about the POW officers of the U 27 crew.

U 25 - North Atlantic - 07:00 - After 2 hours and a half of work, gun ready again (BF 7756). 15:00 - Bad weather. Weapons can no longer be used. No more incidents. PQ: BF7857 → BF7756 → BF7737 → BF7468

U 26 - North Atlantic - Off Isles of Scilly - 02:00 - Illuminated steamer in sight. He was not stopped, too dark for artillery use. 18:30 - Test dive. 19:00 - Surface. No more incidents. PQ: 48°25' North - 13°25' West

U 33 - North Sea - 10:00 - Alarm dive in front of an aircraft (AN 2210). Without bombs. PQ: AN 2210

U 34 - North Atlantic - Under way, nothing special. PQ:AM

Hello to all :D; more..................

War with Great Britain and France!

On November 2, 1939 The BdU is of the opinion that there is a choice between letting the U-boats sail alone at long intervals or retaining the former until they can all operate together. I have decided on this last course, because I would like for once to have several submersibles in navigation and operating outside of Gibraltar. So far such an operation has been planned but never carried out as events took a different turn.

U 26 reported that she had passed 45° north. The other 2 submersibles in this wave (U 25 and U 53) will remain in their areas of operations for about 3 more days so that U 26 has enough time available to carry out its operation.

U 25 - North Atlantic - 00:00 - No traffic west of the area of ​​operation. She returned to the steamer route (BF 7165). 08:00 - The use of weapons is possible again. Patrolling in the area of ​​operations. Nothing sighted from what was reported by other submersibles. Even aerial surveillance didn't spot anything. 14:00 - Patrolling the vapor route (BF 7364). 14:20 - Two steamers in sight. A Dutch and a Belgian. The Dutch ship AMTELKAK was not stopped, too far away. The Belgian steamer BURGES was stopped and inspected. No contraband, released. 20:30 - A very large Japanese liner passed by. No more incidents. PQ: BF7165 → BF7364 → BF7366

U 26 - North Atlantic - Vizcaya - 18:10 - Test dive. 18:50 - Surface. 20:12 - Broadcast of radio message 1315/2/80: "Crossed 45° north to 13° west. Broadcast position: 44° 10' north-13° 20' west." No more incidents. PQ: 45°07' North - 13°17' West

U 33 - North Sea - 08:50 - Dive of alarm due to an aircraft. PQ: FA

U 34 - North Atlantic - Nothing special to report. PQ: AM

Hello to all :D; more..................

War with Great Britain and France!

On November 3, 1939, the Naval Warfare General Staff asked the BdU to address the issue of attacking England's timber imports from northern Russian ports. These imports are considered of great importance. Regarding timber shipments from the northern Russian ports to GREAT BRITAIN, DÖNITZ believes that the problem will be resolved at the political level. In any event, Dönitz had planned to operate with U 36 against these timber transports in the area east of the North Cape. He believed that the chances of success are good in this area, but he could not decide further until he had information on the status of this operation.

The Naval Warfare General Staff also informed the BdU at the same time that there was a possibility of establishing a "Northern Base". Dönitz thought that everything possible should be done to clarify this matter. The base would also have to have reliable radio communication with the submersibles and with the Motherland. Since a large-scale operation could not be kept secret for long, there would have to be military protection from the start to prevent surprise raids by the enemy.

In the Naval Warfare General Staff, the use of the Navy as a support measure in the event of a Western campaign is discussed as part of a conference. Depending on weather conditions, submarines will be used as mine and torpedo carriers. For the deployment of submarines, an advance announcement with keywords of at least five days is required.

The German Naval Attaché in WASHINGTON announces the establishment of regular British convoys in the Caribbean. Kingston in Jamaica is named as the assembly point for general cargo, and Trinidad as the departure point for oil transportation. The name of the convoy is given with the letters KJ and numbers.

The listening service, the B-Dienst intercepts a report of a British aircraft attacking a submarine north of the HEBRIDES at 10:50. The U-boat escaped by going into a dive. The attack was directed at U 37.

The BdU received from the OKM the names of the officers of U 27 prisoners of war and was ordered to inform the relatives.

U 25 - North Atlantic - 02:05 - Greek steamer KORTHION HELLA stopped and inspected (BF 7655). Released. 08:00 - Navigation in zigzag general course (BF 7655). 11:55 - Submerged. 15:10 - Surface. The Danish steamer DAGMAR stopped and checked. Released. 16:20 - The Belgian steamer GIRONDE was stopped and searched (BF 7671). Released. All ships do not have contraband on board. When the warning shot was fired in front of the GIRONDE's bow, the airlock of the forward torpedo tube broke due to the strong vibration. Limited diving capacity. Non-operational gun. The commanding officer: "Because the boat is only partially ready to submerge when there is strong enemy resistance, the gun is no longer operational and other failures that have occurred before (bow dive plane failure, periscope unit failure , strong formation of oil smoke when navigating on the surface) seriously impair the combat readiness of the submersible, I decide to start the return march". PQ: BF 7655 → BF 7671

U 26 - North Atlantic - Cape Finisterre - 10:20 - Approach to the Spanish coast. 13:30 - Submerged. Works on the torpedoes. 17:00 - Surface. Navigation on the water. No more occurrences. PQ: 41°55' North - 13°00' West

U 33 - North Atlantic - Nothing special to report. PQ: AM

U 34 - North Atlantic - Nothing special to report. PQ: AM
