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

War with Great Britain and France!

On November 30, 1939 Conference of the BdU in the Naval War General Staff on the current state of submarine warfare and future intentions. DÖNITZ gives a detailed report on previous successes in the trade war, the use of mines, and difficulties with torpedo misfires. It also provides status information for submarine crews and provides an assessment of enemy action. For the next period, one of the focuses of submarine operations will be mine laying of British port facilities, specifically FIRTH OF FORTH, FIRTH OF CLYDE, BRISTOL KANAL and the maritime area off LIVERPOOL. At the same time, minor operations will take place against the ports of NEW CASTLE and LOWESTOFT on the east coast. For later assignments, FALMOUTH, PLYMOUTH, ST. ALBANS HEAD, ST. CATHERINES DEEP, ROYAL SOVEREIGN and DUNGENESS. He points out that in addition to minelaying operations, the use of torpedoes must be maintained. The BdU does not consider the use of submarines off the Norwegian coast very promising. It is also pushing for the construction of U-tankes, preferably small or medium rather than large. Naval War General Staff decides to build at least two of these units, which will speed up. DÖNITZ is still given the task of preparing for a mine laying in HALIFAX.

Mine warfare has 2 objectives.

1) Attacking military bases (in continuation of the attack on Scapa Flow) in order to expel the enemy from the ports near the North Sea. Operating along these lines, the BdU carried out mine laying operations in early November at Loch Ewe, opposite the Invergordon entrance, and at the Rosyth entrance to the Firth of Forth.
2) Attack the enemy merchant marine. For this, the following fields were established:
2 in the Bristol Channel
1 outside of Shambles (Portland)
1 outside of South Goodwin
2 outside Orfordness
2 off Lowestoff
1 outside the Newark Lightship
1 outside of Inner Dowsing
1 off Flamborough Head
1 out of Middlesborough (Hartlepool).

It seeks to close the Bristol Channel by adding to the 2 minefields already placed. The minefields that will now be laid by U 26 and U 29 off Milford Haven and Swansen also fall within this framework.

U 28 is in position BF 1367, forward torpedo tubes loaded with mines.

U 29 gives up trying to establish the barrier at MILFORD and proceeds to BRISTOL.

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

War with Great Britain and France!

On December 1, 1939, the meteorological observation ship SACHSENWALD and the accommodation ship CORDILLERA arrive at SAPADNAJA-LIZA Bay. They reinforce the so-called BASIS NORD.

In an informative session of the Naval War General Staff, the consequences of DIRECTIVE No. 9 of November 29, 1939 for the Navy are discussed.

The second order to U 35 has gone unanswered. Since each radio message is broadcast at various times on long and short waves, it is impossible for the boat not to have received it. Either her radio doesn't work or something happened to her.

U 26 - North Atlantic back to port. AM 33.

U 28 - North Atlantic. AM 97.

U 29 - North Atlantic. U 29 arrives in its area of operations off BRISTOL. The submersible cannot carry out her minelaying task due to bad weather and the moon being too bright, and it aborts the operation (AM 9869). AM 98 / AM 9869.

U 31 - North Sea. 05:50 - U 31 sights the Finnish steamer ARCTURUS and begins its approach maneuver. 09:30 - U 31 launches a torpedo and sinks the Norwegian steamer ARCTURUS (1,277 BRT) (AN 4547 / 57°39'N - 00°36'E), which takes nine crew with her, 17 crew survive the sinking. The ship carried tea, shoes, gas ovens, steel cables and machinery on board. A first attack on this steamer (09:27) failed due to a missed torpedo. 17:00 - A torpedo is launched at a sighted tanker, but the shot misses. AN 4489 / AN 45 / AN 4547.

War with Great Britain and France!

On December 2, 1939, Foreign Affairs is considering issuing a warning to the neutral countries NORWAY and GREECE threatening to revoke their neutral status if both nations do not agree to stop chartering space to the United Kingdom. The plan receives the support of the Naval War General Staff.

Beginning of a German propaganda offensive against GREAT BRITAIN, whose axis is a poem by the British RUDYARD KIPLING that was written about the submarine crisis in the First World War.

U 26 - North Atlantic/North Shetland Islands - Marching back. 10:30 - Submerged. steamer in sight. Too far. Working on the torpedoes. 13:25 - Surface. march on the water. No more occurrences. PQ:AM.

U 28 - North Atlantic - Waiting for favorable weather for the minelaying operation in Swansea Bay. PQ: FB.

U 29 - North Atlantic - Submerged. 08:30 - 18:30 mines exchanged for two torpedoes (AM 9797). PQ: AM 9797.

U 31 - North Sea - No special incidents. PQ: AN.

U 36 - Kiel/KWK/Wilhelmshaven - 00:10 - Departed from Kiel (AO 7727). Beginning of the patrol. Marching through the Kaiser Wilhelm Canal to Wilhelmshaven. Arrived in Wilhelmshaven the same day (AN 9814). PQ: AO 7727 → AN 9694 → AN 9814.

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

War with Great Britain and France!

On December 3, 1939, it is appreciated that U 30 and U 32 will be ready to sail approximately on December 10. The BdU intends to give both submersibles mine laying operations. By their radius of action, they are limited to the area around England, where weather conditions are currently unfavorable for torpedo operations, while long nights aid minelaying near the coast. U 32 will mine off the Clyde with the large TMCs, which have already been completed (load 1,000 Kg). U 30 will head for the Irish Sea, off Liverpool. I think this last operation should be very successful because:

1) There is a lot of merchant ship traffic here.
2) So far no U-boats have appeared in this area.

British radio announced the sinking of a German submarine whose crew had disembarked in a Scottish port. So far similar reports from the enemy have been found to be correct. U 35 must be considered lost. Nothing has been heard from U 28 or U 29, which should have already carried out their operations, and it is feared that something has happened to them too. But it is also possible that they are waiting for the new moon to lay their mines. In that case they must report in the next few days.

U 26 - North Sea/East Shetland Islands - 07:00 - Due to transfer, heading for the Norwegian coast. 10:00 - Submerged. Ship in sight. Torpedo reloaded. 11:55 - Surface. Two steamers in sight. dodged. 14:30 - Submerged in front of small steamers. 16:40 - Surface. Navigation on the water. At night, in the far south of Norway, up to Cape Skagens, many steamers are visible. No more occurrences. PQ: 60°04' North - 03°40' East.

U 28 - North Atlantic - Awaiting favorable weather for minelaying operation in Swansea Bay. PQ: FB

U 29 - North Atlantic - Submerged (BF 1130). 08:15 - 18:30 - More mines exchanged for three torpedoes. Storm going on. Ineffective surface navigation. PQ: BF 1130

U 31 - North Sea - 08:50 - The Norwegian Hosanger sighted. No attack 12:55 - Sighting of suspicious Danish steamer. 13:20 - Torpedo against steamer (AN 5191). Impact. The Danish OVE TOFT was sunk. Six crew members of the OVE TOFT lose their lives when the ship loaded with coal sinks. 23:10 - Three steamers sighted (AN 5318). Torpedo against the most easterly one misses. PQ: AN 5191 → AN 5318

U 32 - Wilhelmshaven/KWK/Kiel - 07:00 - Sailed from Wilhelmshaven (AN 9814). After staying at the shipyard, the ship sailed the Kaiser Wilhelm Canal to Kiel, where she moored at 21:31 (AO 7727). There are more tests and trials. PQ: AN 9814 → AN 9694 → AO 7727

U 36 - Wilhelmshaven/North Sea - 13:35 - Sailed from Wilhelmshaven (AN 9814). She marches to the North Sea area of operations. PQ: AN 9814

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

War with Great Britain and France!

On December 4, 1939, letters from captured crew members indicate that U 40 struck a mine. This is the first proof of mines in the Canal. So far no aerial reconnaissance of the Dover-Calais Strait has been carried out. Now Dönitz decided to abandon this route to the Atlantic; there should be no losses in the passage. With so few submersibles, each loss means such a significant reduction in forces that it outweighs the disadvantages of a long and fruitless voyage.

U 26 - North Sea/Far South Norway - Skagerrak/North Coast of Denmark - 08:45 - Submerged due small sailing vessels. 10:35 - Surface. Crossing Blue Route 12. 13:50 - Outgoing radio message 1216/4/40: "Location 1200 2709 E". 14:00 - Floating mine sighted. 23:30 - Enter a radio message for the arrival. No more incidents. PQ:AN

U 28 - North Atlantic - Waiting for favorable weather for the mining operation in Swansea Bay. PQ: FB

U 29 - North Atlantic - Nothing special to report. PQ: FB

U 31 - North Sea - Another attack on the three steamers sighted the day before. 01:23 - Torpedo launched. Impact (AN 5316). The Norwegian ship GIMLE was sunk. 08:00 - Surface for crew rest. 15:10 - Steamer sighted. 15:42 - Torpedo launched. Impact. The Norwegian ship PRIMULA was sunk. On the GIMLE, which was loaded with briquettes, three crew members died, 16 survived the sinking. The PRIMULA sailing under ballast claims the lives of eight sailors, seven survive. The British battleship HMS NELSON strikes a mine laid by U 31 off LOCH EWE and is heavily damaged. 73 men from HMS NELSON (33,950 GRT) are wounded (AM 3826). HMS NELSON has to spend four months in dry dock after ramming the mine. PQ: AN 5316

U 36 - North Sea - 16:00 - U 36 (Kapitänleutnant Wilhelm Fröhlich) sunk by torpedo (AN 3761) by the British submarine HMS SALMON (N.65). The entire crew, 40 men, lost their lives. U-36 was at sea for two days at this point. PQ: AN 3761

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

War with Great Britain and France!

On December 5, 1939, the BdU considered it a mistake to send U 25, U 26 and U 53 to the Mediterranean. U 25 had to turn back before getting there, U 53 was unable to get through, and U 26 encountered almost no traffic worth noting. This patrol shows all the disadvantages of a long outward voyage. The submersible can only operate for a few days and the operation is unsuccessful if it finds no traffic in those few days.

The Kriegsmarine Commander-in-Chief, Admiral Erich Raeder visits the BdU Headquarters (Dönitz).

U 26 entered port. She did not carry out her minelaying operation off Gibraltar because the weather there was too bad. She then went to the Mediterranean, as ordered, but apparently found herself at a bad time in terms of maritime traffic.

The result of her patrol is a sunken steamer. Very little for 44 days. Stormy weather is mainly to blame. The commander cannot be blamed for not carrying out the minelaying operation because he did not consider it possible in view of local conditions.

These things can only be judged in the moment. But he did not take long enough to make his observations; he should have made at least one more try in different weather conditions.

U 26 - North Sea/German Bay/Wilhelmshaven - 13:30 - Test dive. 13:45 - Surface. 17:00 - Wangerooge Lighthouse in sight. 21:00 - Passage of the Schillig roadstead. 22:00 - Arrival in Wilhelmshaven/III. Entrance (AN 9814). End of the 2nd Patrol. PQ: AN 9814

U 28 - North Atlantic - Bright night. Throwing the mines into the water (AM 9863). 22:47 - 23:57 - Laying of twelve mines in Swansea Bay. PQ: AM 9863

U 29 - North Atlantic - Nothing special to report. PQ:BE

U 31 - North Sea - No special incidents. PQ: AN

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

War with Great Britain and France!

On December 6, 1939, the BdU requested the Naval Warfare General Staff to extend the limits within which darkened ships can be attacked without warning. This is desirable:
1) in view of the current operation of the U 38 in the Westfjord. The English ships are most likely obscured. Almost all of them are painted gray, to make them less conspicuous, and they are armed.
2) for submarine operations in the Mediterranean and off the Portuguese coast. Returning U-boats say they sighted obscured ships there and were never sure what to do. The action according to the prey law is very difficult and dangerous for the submarine, especially near Gibraltar.

The Naval War General Staff would not give its approval, since there could be German ships off the Norwegian and Spanish coasts.

The German Naval Attaché in Rome, Kapitän z.S. Löwisch, in a meeting with the Naval War General Staff, was ordered to clarify several questions about the future behavior of ITALY. Among other things, what possibilities are there really for the supply of submarines in Italian ports and bases?

The BdU reports that four submersibles are not operational due to sand being found in the engine oil. Submarines are out of action for a week (Affected are U 13, 46, 51 and 52). Background investigations are already underway.

U 28 Atlántico Norte - BF 22 - In the area of operations, without special incidents.

U 29 North Atlantic - BF 3287 - 06:10 - steamer in sight. 06:45 - Torpedo misses. Failure. 07:18 - second shot is Rohrläufer (*). Torpedo ejected. The escorts appear. Evade.

U 31 North Sea - AN 5341 - 06:15 - steamer sighted. 07:54 - Torpedo hit the ship. Impact. The Estonian ship AGU (1,575 GRT) and loaded with coal was sunk. There were no survivors. The captain and 17 crew members were killed. 18:00 - three steamers in sight. Attack the ship to the east. AN 4887 - 23:49 - Torpedo over the ship. Impact. The Swedish ship VINGA (1,974 GRT) was sunk. Loaded with coal, it was heading from the Tyne (Great Britain) to Gothenburg (Sweden). There were no deaths.

(*) When a torpedo to be launched gets stuck in the tube or cannot be released from the tube for other reasons.

War with Great Britain and France!

On December 7, 1939, the BdU received a negative order from the Naval Warfare General Staff regarding its request the previous day to extend the attack zones for submarines, which again essentially refers to the return of camouflaged German merchant ships from Norwegian and Spanish ports.

14:54 hours, all submarines receive a warning from FdU WEST about an obstacle to navigation at position 55°52'N - 00°37'W, which is probably a drifting wreck.

U 29 reported that she was returning. The boat was unable to carry out its mine laying operation due to anti-submarine activity and weather conditions (11 days of gales) and now she has to return home because her fuel reserves are depleted. Thank God our fears for her safety were unfounded.

U 28 North Atlantic - BF 13 - In the area of operations, without special occurrences.

U 29 North Atlantic - AM 77 - In the area of operations, without special occurrences.

U 31 Mar del Norte - AN 45 - In the area of operations, without special occurrences.

War with Great Britain and France!

On December 8, 1939, Conference of the Head of the Naval War General Staff to Hitler. RAEDER deals with the mine-laying operations of the German submarines in the British coasts, gives a report on the incursion of the U 26 in the MEDITERRANEAN, talks about the Allied convoys from NORWAY to the SHETLANDS, and about the planned operations with TMC mines with new proximity magnetic fuzes. Among other things, problems in the construction of submarines are again addressed. In addition to Hitler and RADER, Generaloberst KEITEL and KoKp von PUTTKAMER present.

The B-Dienst presents the situation in the HOLLAND-GREAT BRITAIN traffic as follows: The cargo ships assemble at NORDHINDER between 10:00 p.m. and 11:00 p.m. and are then taken under escort there by the British naval forces between 23:00 and 02:00 hours.

U 28 - North Atlantic - 20:00 - Started return. Fuel still 30 m³ (AM 7940). PQ: AM 7940

U 29 - North Atlantic - In the area of operations, nothing special. PQ: AM

U 31 - North Sea - 11:40 - Steamer in sight (AN 4855). She disappears in a rain shower. 16:00 - Steamer in sight again. It waited until she got dark with the attack. 19:00 Torpedo on the steamer (AN 4876). It failed and detonates behind the ship. Lost, marching back. PQ: AN 4855 → AN 4876

On December 9, 1939 The B-Dienst reports the departure of a convoy of 50 ships with an escort of two British destroyers and two French destroyers, as well as four other escorts on December 8, 1939 from Gibraltar.

The WEHRMACHTSBERICHT announces the following message: ... The British Admiralty confirms that the destroyer HMS JERSEY was torpedoed on December 07 by a German submarine.

The U 30 sailed towards her area of operations. Mine laying off Liverpool.

U 28 - North Atlantic - Return march, nothing special.

U 29 - North Atlantic - In the area of operations, nothing special.

U 30 - Wilhelmshaven - 04:00 - Set sail. Beginning of the 2nd patrol. On board 12 mines and 6 torpedoes.

War with Great Britain and France!

On December 10, 1939, the Naval War General Staff begins preparations to supply food and fuel to Soviet U-boats. These boats are supposed to blockade FINLAND. In return, it will have the ability to supply German units at any desired location. Preparations begin after Hitler's approval. Since normal steamers have no fueling facilities, a ship must first be converted, accordingly the German Attaché in MOSCOW is instructed to obtain more detailed requirements from the Soviet government.

There is no news from U 28 and this is cause for concern. If until now she has not been able to place her mines due to the weather and the moon, at least she should be able to decide now, with a new moon and calm weather, if she can place them. In any case, her fuel supply should have forced him to turn back by now.

U 28 - North Atlantic - AM 48 - On the way back, nothing special.

U 29 - North Atlantic - AM 34 - In the area of operations, without special incidents. Return.

U 30 - North Sea - AN 63 - On the way towards the theater of operations. When the sea is rough, there is a lot of water in the submersible. 7% water in the lubricating oil. The pumps do not suck. Manual pump drainage.

U 31 - North Sea - AN 37 - On the way back, nothing special.

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

War with Great Britain and France!

On December 11, 1939, the Naval War General Staff encourages a propaganda exploitation of the British announcement about the new regulation of maritime traffic in British waters and estuaries. In effect, all of these maritime areas would become war zones and lose their status as peaceful trade routes. In this case, the German Naval Warfare General Staff would bear no responsibility if the neutral ships were victims of acts of war in the future.

All U-boats operating in the northern North Sea are prohibited from attacking steamers sailing without lights by FdU WEST. The background is the attempt by BREMEN, which is trying to reach Germany from Murmansk.

U 30 reported from the northern North Sea that her port exhaust valve did not close. The submersible was in the shipyard from October 9 to December 5, during which time the motor casing was changed and the immersion cells were modified. She set sail on December 09. If the exhaust valve cannot be repaired at sea, the boat will not be able to submerge and will therefore be forced to discontinue its patrol. This means that the operation will have to be postponed until the next new moon. After that long stint in the yard, it's not too much to ask for the exhaust valve to be in good working order. If the U 30 has to interrupt her operation, I will demand (Dönitz) a thorough investigation by the shipyard to determine who is to blame.

U 31 entered port. She had it kept away from Orkney for a time, in connection with an operation by our own surface forces, and then it operated in the North Sea.

In the evening a report was received from U 28. It was thought that she had been lost. She has been on her way home for several days and has carried out her minelaying operation. There couldn't be better news today! The German submarine branch has one more submersible than we thought.

U 28 North Atlantic - AM 43 - Back, without special incidents.

U 29 North Sea - AN 21 - Marching back, without special incidents.

U 30 North Sea - AN 2975 - Marching towards the area of operations. Port outside exhaust valve will not close. Stopped. Seven hours of attempted repair. Problem not found.

U 31 North Sea/Wilhelmshaven - AN 98 - 22:45 - Arrival in Wilhelmshaven. Finish of the 4th patrol.

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

War with Great Britain and France!

On December 12, 1939, the German Naval Attaché in MOSCOW informed the Naval Warfare General Staff by telephone that the SOVIET UNION would not be able to supply its submarines with German merchant ships. Then all measures initiated in this regard will be stopped. The High Command regrets this development given the future possibility of supplying its own units.

U 30 has been unable to repair her exhaust valve and is returning.

The fate of the U 35 is now known. A Scottish newspaper photo shows the Commander and some crew members. British radio has released several names of crew members of the submersible. The U-boat has been declared missing as of December 12.

U 28 - North Atlantic - AM 2624 - Return march. 2048 - Torpedo over steamer sighted misses. detonated prematurely. 21:05 - second torpedo against the steamer. Grundgänger (propulsion failure and torpedo sinks). Passed.

U 29 - North Sea - AN 22 - Return march. Radio message received: Proceed to Kinnaird Head. Take advantage of attacking opportunities.

U 30 - North Sea - AN 38 - March towards the area of operations. Diving test. The exhaust valve failure remains. return march. Port cylinder, 5 seized piston pins.

On December 13, 1939, at a meeting of the Naval Warfare General Staff, the annexes to the Führer's Directive No. 8 will be discussed. As before, the time limit for land operations of surface and submarine forces remains in effect for the Yellow Case (Fall Gelb).

An English submersible successfully attacked some of our light surface forces in the North Sea. So that as extensive an anti-submarine search as possible can be organized, all submersibles in the North Sea were ordered to report positions.

U 28 - North Atlantic - AM 31 - Return march, without special incidents.

U 29 - North Sea - AN 18 - Return march. AN 1864 - 0800 - Kinnaird in sight 4-6 NM. There is no traffic except for trawlers. The withdrawal continued.

U 30 - North Sea - AN 95 - Return march, without special incidents.

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

War with Great Britain and France!

On December 14, 1939, the case of the U 30 led me (Dönitz) to take up the whole issue of shipyard repairs and to contact the Admiral Superintendent. Torpedo failure has had a very negative effect on submarine operations. The material weaknesses of the submersibles are no less important and seem to have become more apparent since the motor casings were changed. Even if this matter is resolved, there remains the fact that the periods in the shipyard are very long compared to the number and duration of the patrols and that this situation cannot continue.

1) One of the reasons for the long periods in the shipyard is the defects in the U-boats that are only coming to light now in the war and can lead to losses.
2) Long periods in the yard mean there are many boats in the yard at once, leading to a shortage of skilled labor and supervisors. Personnel not trained in submarine work cannot replace skilled workers. Therefore, skilled workers are overworked or untrained men make mistakes that mean an even longer period in the shipyard.
3) The periods in the shipyard must be shortened through a rigid organization of work.

On December 5th I had a conference with the Admiral Superintendent of the Shipyard to discuss these matters. The following was established:
a) that short shipyard periods of 3-4 weeks are necessary after the patrols, in addition to changing engines and making other alterations.
b) that the number of trained shipyard personnel must be increased to meet the increased demands.
c) The work elements must be organized by the shipyard quickly and efficiently. The length of shipyard periods for operational submersibles must be reduced at all costs.

U 28 - North Sea - AF 78 - Marching back, nothing special.

U 29 - North Sea - AN 48 - Marching back. AN 4838 - 10:30 - While attacking a sighted oil tanker, air strike. Alarm dive. At 40 m nearby aerial bombs. 14:00 - two more depth charges at a distance of 3 - 4000 m.

U 30 - North Sea/Wilhelmshaven - AN 98 - 02:00 - Arrived at Wilhelmshaven due to damage. Valve and clutch repair.

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

War with Great Britain and France!

On December 15, 1939, the "Graf Spee" is damaged and has entered Montevideo after her action in the South Atlantic. The Naval War General Staff has asked the BdU what support the submarines could give to the pocket battleship in front of the mouth of the Plata. I have (Dönitz) assured the Naval War General Staff that I will do everything I can and I am determined to try everything possible, despite the great difficulties involved in such an operation with submarines.

Two submarines (U 44 and U 46) can be prepared in time to arrive at Plata in early February. The operation mainly depends on the supply issue. It will be necessary to refuel on departure, on return and in the area of operations. The Naval War General Staff promises supplies in the Canary Islands and in front of La Plata from the "Altmark". This means that the operation can be attempted. It means going to the tropics and there is no submarine experience in these areas. Preparations must be made accordingly.

Special attention should be paid to food, clothing and medical matters in view of climate changes, high temperatures and strong sun. Torpedo fuzes, electric torpedo batteries, and ammunition are also likely to be affected. The necessary measures are being taken immediately.

The German Attaché in WASHINGTON reports that a convoy left HALIFAX on December 12, 1939. The mail steamers EMPRESS OF BRITAIN and EMPRESS OF AUSTRALIA will also travel on this convoy. The convoy will carry 10,000 troops and 700 aircraft and will be secured by two cruisers and five destroyers.

U 28 - North Sea - AN 23 - Marching back, nothing special.

U 29 - North Sea - AN 91 - Marching back, nothing special.

U 30 - Wilhelmshaven - AN 98 - Repair of exhaust valve and clutch.

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

War with Great Britain and France!

On December 16, 1939, the BdU receives the message that the use of submarines to support the GRAF SPEE in MONTEVIDEO will be cancelled. Political events leave no more time for an operation of this type.

U 29 entered port. She had an unlucky patrol. The U-boat did not sink anything and did not carry out its minelaying operation. The Commanding Officer obviously made the mistake of thinking that all the activity of the enemy patrol boats and suspicious vessels was directed specifically against his boat, so he achieved nothing. He will be ordered a similar operation next time to correct this error.

U 28 - North Sea - AN 49 - Marching back, nothing special.

U 29 - North Sea/Wilhelmshaven - AN 98 - 12:00 - Arrival in Wilhelmshaven. End of the 2nd patrol.

On December 17, 1939, the Commander of U 23, Kplt. KRETSCHMER reported himself to FdU WEST late in the afternoon to inform on their task of reconnaissing and clarifying the situation in the ORKNEY AND SHETLAND ISLANDS.

U 28 - North Sea - AN 92 - Marching back, nothing special.

On December 18, 1939, the German Attaché in WASHINGTON announces the departure of an Allied convoy from the St. Lawrence River. The convoy will consist of eight British, four French and two Norwegian ships and, in addition to food, will also carry a troop transport with air force personnel.

U 28 entered port. She conducted her minelaying operation in the Swansea shaft. She also sank:

1) tanker "Sliedrecht" 5,130 tons
2) steamer from the convoy presumably "Royston Grange" 5,144 tons
In total 10,274 tons.

U 28 - North Sea/Wilhelmshaven - AN 98 - 08:30 - Arrival in Wilhelmshaven. End of the 2nd patrol.
