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

War with Great Britain and France!

On November 15, 1939, radio intelligence reports have provided the following information on the whereabouts of the British battle fleet:
1) battleships and battlecruisers and various aircraft carriers are not in territorial waters, but in special operations.
2) Most of the remaining battleships apparently mainly use the Firth of Clyde as anchorage.

The U-boats cannot attack the anchorages themselves, but it would be quite possible for the subs to penetrate the widest part of the Firth, right up to the boom. This operation must be carried out as soon as possible. There is a good chance of catching large warships. However, it will be necessary to use mines with a higher explosive effect than TMBs, as they cannot be guaranteed to sink if placed at this depth.

The operation of many submarines against the Home Fleet in the Firth of Clyde will therefore only be worthwhile if carried out in cooperation with own surface forces.

U 26 - Mediterranean Sea/North of Alborán - In Operations Zone. Submerged at dawn. Port diesel 4 piston removed and replaced. Total duration 25 hours. 18:20 - Surface. Night patrol along the steamer route north of Alborán. No sightings. No more occurrences. PQ:CH

U 28 - North Atlantic - Nothing special to report. PQ:AM

U 29 - North Sea - Marching towards the area of operations (AN 62). 08:15 - Submerged (AN 6529). U 38 is coming astern. She let her go. PQ: AN 62 → AN 6529

U 33 - North Atlantic - 00:10 - Steamer in sight (AM 5538). Attack. Steamer disappears in a flurry of rain. PQ: AM 5538

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

War with Great Britain and France!

On November 16, 1939, the B-Dienst reports the Allied convoy HX-9 underway from HALIFAX to GREAT BRITAIN. According to these reports, the convoy will be taken by British units of WESTERN APPROACHES in the position 48° north – 29° west. In fact, the convoy reported as HX-9 must be the HX-8F fast convoy.

The Naval War General Staff draws up a memorandum on the use of German submarines in the MEDITERRANEAN. The central content is the behavior of TURKEY in the event of such an operation in the EASTERN MEDITERRANEAN. Prospects for success are rated as good, assuming the element of surprise.

The next submersibles in the fleet to be ready to operate will be:
U 31 and U 35 on November 18
U 36 on November 25

The BdU intends to send U 31 and U 35 to the southern Irish sea area and allow them considerable freedom of action there. They must be able to approach shoreline or move out to sea depending on weather conditions and patrol. Initially the U 28 and the U 29 will be in the same area.

U 26 - Mediterráneo/NW Alborán - 06:30 - Submerged. steamer in sight. scheduled attack. 09:50 - Aborted, She is Swedish. 12:15 - Dive in front of a boat. misjudgment. It was the island of Alborán. Low traffic. 13:15 - Surface. Intent: Drop decoy periscopes overnight and then return, otherwise the fuel will run out. PQ:CH

U 28 - North Atlantic - Nothing special to report. PQ:AM

U 29 - North Sea - No special incidents. PQ:AM

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

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

War with Great Britain and France!

On November 17, 1939, the order from the Naval War General Staff was received to the effect that unrestricted measures may be taken against passenger ships that appear to be armed. Since most passenger ships are already armed, this will be a big step forward. In practice, of course, U-boats will only be able to attack passenger ships that they can recognize as armed.

U 53 reported another convoy off Lisbon, 18 ships in 4 columns, 5 destroyers escorting. Speed 7-8 knots, main heading north. It is clearly the same convoy that the Radio Intelligence Service picked up on November 16 and fixed several times. It is valuable to have the radio intelligence report confirmed by a submarine. If the reports continue to be as accurate and arrive at such good time, they will be of great use in the conduct of the war. U 41 and U 43 are still far to the north. It is known from experience that it is still too early to order them to operate against this convoy; but they are moving south and should be level within 2 days.

The Home Fleet is located in the north and northwest of Scotland. U 29 is roughly north of Shetlands. This U-boat has been informed.

DÖNITZ receives instructions from the Naval War General Staff to test the BASIS NORD with U 36, whose departure is scheduled in the coming days.

U 26 - Mediterranean Sea/East of Ceuta - 08:00 - Submerged. underwater during the day. Without traffic. 19:00 - Surface. Patrolling with a machine. Launch of dummy periscopes. 23:00 - Return through the Strait of Gibraltar. 24:00 - Ceuta Lighthouse through. PQ: GC

U 28 - North Atlantic - 00:20 - The Dutch steamer SLIEDRECHT (5133 BRT) was stopped (AM 5142). The ship was supposed to go to Norway, but the British diverted it to Kirkwall. The crew enters the lifeboats. The steamer was sunk by a torpedo hit after the crew abandoned ship. However, 26 crew members lose their lives, only five make it to land (AM 5142). The SLIEDRECHT was carrying 6,600 t of fuel of different types. PQ: AM 5142

U 29 - North Sea - Marching towards the theater of operations. 04:30 - Defective port diesel (AN 2728). Submerged to repair. There was a screw in the sixth cylinder. Changed intake valve. PQ: AN 2728

U 33 - North Atlantic - No special incidents. PQ:AM

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

War with Great Britain and France!

On November 18, 1939, the B-Dienst again located the allied convoy HX-8F, referred to here as HX-9. According to these reconnaissance findings, the convoy is 350 nautical miles west of LA ROCHELLE at 10:00 hours and is being covered by the battleship HMS RESOLUTION with a cruiser and destroyer escort. The convoy is expected on November 19 on the BRISTOL Channel. U 53 continued to pursue the convoy.

U 31 and U 35 sailed for their respective areas of operations in accordance with Operations Order No. 13. However, U 31 had to re-enter port due to engine trouble.

U 26 - Strait of Gibraltar - 02:15 - Submerged. Advance through the Strait of Gibraltar towards the North Atlantic. 03:30 - Tarifa across. Outlet of the Strait just below the African coast. 04:10 - Submerged due a destroyer. Submerged for the rest of the day. 19:00 - Surface. March along the steamship route to Cape San Vicente. 20:00 - Three or four shadows sighted. Large ship with multiple destroyers. Too bright for a surface attack. Nothing to see on the periscope, the direction was quickly lost on the listening device. 21:00 - Surface. Navigation on the water. No more occurrences. PQ: GC

U 28 - North Atlantic - Nothing special to report. PQ:AM

U 29 - North Sea/North Atlantic - 06:10 - Rounding the northern tip of the Shetland Islands (AN 1161). Sea 5. 20:00 - The Swedish steamer PAN GOTHIA was stopped. No contraband. PQ: AF 7850 → AN 1161

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

War with Great Britain and France!

On November 19, 1939, contact with the convoy was lost after it changed course just before dawn, just at the critical moment. In the afternoon the other submersibles could have been there. However, by 13:30 U 53 had made contact again. The others should have been around. It must be borne in mind that they have been in the northern operational areas for several days in bad weather. Considerable errors in E.P. were to be expected. U 53 was therefore ordered to make beacon signals.

At 18:20 contact was lost again, but only an hour later U 41 sighted the convoy. It had ocurred; a second submersible had been brought up to the convoy. Nothing was heard from U 43, but this does not necessarily mean that she was not there. She had no reason to report, as the enemy was under constant observation.

After a long silence, U 26 reported from the west of Gibraltar. The U-boat had not carried out the mining operation.

U 26 - North Atlantic/Tarifa - San Vicente - Marching back. 08:50 - Submerged. Two steamers in sight. Planned submarine attack. Both steamers have Spanish markings. 11:00 - Steamer in sight. It's Italian 15:00 - American liner in sight. 16:30 - Surface. March along the Portuguese coast. Lots of fishermen. 23:20 - Outgoing radio message 2213/19/67: "Withdrawal started." No more occurrences. PQ: GC

U 28 - North Atlantic - Nothing special to report. PQ: FB

U 29 - North Atlantic - 14:05 - Alert dive in front of an aircraft (AM 3497). Two aerial bombs, no damage. PQ: AM 3497

U 31 - Wilhelmshaven/North Sea - 15:58 - Sailed from Wilhelmshaven (AN 9814). Beginning of the 4th Patrol. PQ: AN 9814

U 33 - North Atlantic - 14:30 - Steamer sighted (AM 5531). Dive approach. 17:10 - Surface. Vapor is the neutral Greek MOUNT KASSION. Attack without effect. Purpose of the return march: Destruction of the trawlers in front of the North Channel. PQ: AM 5531

U 35 - North Sea - No special incidents. PQ:AN
