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

The U-Flotille "Hundius" and its oceangoing U-boats.

War with Great Britain and France!

On September 7, 1939, a dilemma was presented to the U-Bootwaffe, to decide whether the Atlantic U-boats will operate against merchant shipping or against the British naval forces. Real success against naval forces can only be expected if they are brought out of ports into the open sea. Our surface forces are so weak that they can hardly achieve this. It is conceivable that the main body of the English fleet, believed to be in Scapa, could be driven off by airstrikes. But air strikes are not a policy at the moment, so it was decided, in accordance with my proposal, to continue using the U-boats against merchant shipping.

According to what was proposed and according to the radio message transmitted at 7:02 pm, the order was issued to return to their ports of origin to the U-boats of the “Hundius” and “Wegener” flotillas.

U 37 North Atlantic - 8:18 - Torpedo against sighted British steamer DEFENDER fails (CG 1629). Early detonation. 21:41 - The torpedo against the British steamer "TAMAHA" (CG 1385) fails. 21:43 - The second torpedo against "TAMAHA" went out of control. Destroyed.

U 38 North Atlantic: in the area of ​​operations. Radio message received (CG 5210): order to return.

U 39 North Atlantic - In the area of ​​operations, without special occurrences (AM 27). Order to return received.

U 40 North Atlantic: in the area of ​​operations, without special occurrences. 21:00 - Radio message received (CF 9839): start the return journey. Navigation to the base began.

U 41 North Atlantic - 06:30 - The Island of Santa María, of the Azores in sight (CF 8150). 21:30 - Radio message received: start of the sail back to the north of England (CF 7150). Return navigation.

The U-Flotille "Hundius" and its oceangoing U-boats.

War with Great Britain and France!

On September 11, 1939, an intelligence report (radio listening) was received reporting on the sinking of the S.S. Firby (4683 TPB) on Grid 1366 AM west of the Faroe Islands. This success should have a very strong effect, as so far no submarines have appeared in this area (victim of U 48). Intelligence reports via radio listening on convoys are coming in in increasing numbers. The assembly area in the Bristol Channel is still being broadcast to U-boats. Otherwise, there is no clear image.

The FdU received the directive that all ships with cargo for Great Britain or destination ports in countries that declared war on Germany or severed relations must be stopped and investigated. For the Atlantic, all the previous provisions remain in force. In the afternoon of the same day this instruction is revoked.

U 37 North Atlantic - On the way back. Six empty ATHENIA's lifeboats (AM 1870) were sighted.

U 38 North Atlantic - On the way back. 12:35 - The American steamer STEWARD (BE 6232) stopped. No prohibited products. 13:50 - The British steamer INVERLIFFEY (BE 6337) stopped. The ship sails to London. Crew delivered to STEWARD. Ship sunk by torpedo. The entire crew of the INVERLIFFEY survived the sinking (48 ° 14 'N - 11 ° 48' W) of the tanker loaded with 13,000 t of fuel. The ship was flying the Irish flag at the time of being stopped.

U 39 North Atlantic - On the way back, without special incidents (AM 20).

U 40 North Atlantic - On the way back. Immersion alarm for rapidly disappearing steamer (BE 2614).

U 41 North Atlantic - On the way back. 13:29 - Submerged in front of the Norwegian steamer DAGMARHOLM (BE 3771). Nothing suspicious. However, she was actually the British steamer DAGMAR.

The U-Flotille "Hundius" and its oceangoing U-boats.

War with Great Britain and France!

On September 14, 1939, a conference was held with the Admiral Superintendent of Maintenance about the torpedo situation. Maintenance had stated that all delivered G7es were adapted for shooting at an angle. Consequently, the submarines were informed on September 7. Then, on the afternoon of the 13th, he reported that a gyro-angle equipment had been installed, but the queues had not been adapted. These errors must not occur. It remains to be seen if this has caused errors. 90 degree angle shots canceled.

The Radio Intelligence Service reports that the Vancouver City, British Influence and Fanad Head steamers have been sunk; the sunk tonnage has thus passed the mark of 100,000 t.

U 37 North Sea - AN 34 - On the way back, without special incidents.

U 38 North Atlantic - AM 2942 - On the way back. 04:40 - three British destroyers spotted. Useless attack.

U 39 North Atlantic - AM 2548 - 15:46 - The U-boat was sunk by escort destroyers after a failed attack with two torpedoes against the aircraft carrier ARK ROYAL. After a failed attack on the British aircraft carrier HMS ARK ROYAL, U 39 was attacked with depth charges and sunk by the British destroyers HMS FAULKNER, HMS FIREDRAKE and HMS FOXHOUND. Since U 39 was still able to emerge, there were no casualties among the crew, all 44 men were taken prisoner by the British. The U 39 was the first German submarine lost in World War II. At this point, she was at sea for 27 days.

U 40 North Atlantic - AM 2640 - On the way back, without special incidents. Sea 5-6, wind 6-7.

On September 16, 1939 in order to obtain more information on the English trade routes, the amount of merchant maritime traffic and the convoy system, a collection of investigation questions was sent to the intelligence service.

By secret message 6559 from the Supreme Command of the Navy, Naval General Staff (1st Division), control of the submarines in the Baltic has been transferred to the FdU / West. The U-boats employed to monitor the KATTEGAT are withdrawn from the F.d.OST area of ​​responsibility and subordinated to the FdU. The submarines employed in the BALTIC SEA will be retired, as their subsequent use cannot be justified due to the lack of targets.
