I couldn't find anything whether the British submersible sighted the German and reported or not, does anyone have any idea about this? Cheers. Raúl M 8-).

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

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

"Fall Weiss".

On August 21, 1939 the BdU asked if all ready U boats should be dispatched or if it would not be better to keep some as relief or operational reserve. The Supreme Command of the Navy decided that all submarines should be employed. The decision was received in the afternoon, the sailing times were reported.

Situation at 21.8:

The equipment was carried out according to plan, except for the operational torpedoes. The excessive number of orders and keywords has been a disadvantage. The transmission of instructions has not been reliable either.

Operational situation: Atlantic U boats are on their way to their positions. The BdU was of the opinion that the convoy system would not go into effect in the first days of the war. A flotilla commander has been dispatched with the submersibles and then a second senior officer (another commander) is intended to be dispatched. Therefore, the U boats can always be divided into a Group N. and S., each under a tactical commander and under the operational command of the BdU.

5 U boats of the U-Flotilla "Hundius" en route to the Atlantic (out of 35 in total)

The Flotilla cannot count with U 42 ​​due to a long period in the shipyard.

U 37 North Sea - AN 28 - to dive twice in front of planes.

U 38 North Sea - AN 23 - In march towards the area of ​​operations, there are no special events.

U 39 North Sea - AN 23 / AN 2262 - In march towards the area of ​​operations, there are no special events.

U 40 North Sea - AN 28 - In march towards the area of ​​operations, there are no special events.

U 41 North Sea - AN 2310 - On hold. 06:30 - U 39 (AN 2310) sighted.

On August 22, 1939, the "ERWIN WASSNER" sailed from Kiel to Swinemünde with the BdU on board, arriving at that place at 7:30 p.m. Operational control: the BdU will exercise operational control as such and also as BdU in the Baltic. It became known about the Non-Aggression Pact with the Soviet Union. Operation "Fritz" canceled (This operation sought to carry out reconnaissance over the Gulf of Finland). An intelligence report (radio listening) about a cruise ship and 8 steamers in the center of the North Sea indicates that convoys have been formed.

Situation at 22.8:

The following U-boats of the flotilla en route to the Atlantic: U 37 / U 38 / U 39 / U 40 / U 41

All available submersibles for the Atlantic have sailed and cannot be relieved. If the situation continues as it is today, or if war breaks out, they will begin to return in mid-September. The Commander of the U-Flotilla "Hundius" aboard U 37. Later, he can take tactical command and if necessary if the situation makes it necessary to change the order of operations.

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

"Fall Weiss".

On August 23, 1939 after the non-aggression pact with Russia, some U-boats are likely to leave the Baltic. By order of the Naval War Staff, the reconnaissance of the Gulf of Finland and the offshore of Gotland has been canceled by the Fall Weiss. Atlantic Operations Order No. 3 was drafted for U 28 and U 53; U 28 will take over operations in the interior area instead of U 37.

U 37 - North Sea - AE 92 - Very bad radio reception.

U 38 North Sea - AF 9? - On the way to the operations area, there are no special events.

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

"Fall Weiss".

On August 25, 1939 at 01:30 hours the keyword "Unternehmen ULLA" was received. Broadcast on "emergency" priority at 01:40 to naval communications officers Wilhelmshaven, List, Borkum, info BdU West.

At 16:36 hours followed the verbal instructions of the Group Command, the key word for the Y-Hour Fall Weiss was communicated to the U-boats. At 20:18 hours, Y-Hour was canceled.

All boats In march towards the area of operations, there are no special events. U 37 North Atlantic - AM 47 - U 38 North Atlantic - AL 37 - U 39 North Atlantic - AM 20 - U 40 North Atlantic - AM 01 - U 41 North Atlantic - AM 43.

On August 26, 1939 U 43 was commissioned in the U-Flotille "Hundius" under Kapitänleutnant Wilhelm Ambrosius.

Contrary to the 1938 plans, it was now not intended to use TMB mines in the English Channel. According to the instructions of the Supreme Command of the Navy, submarines are now to be used only against enemy maritime traffic. Portsmouth, Portland, Plymouth and Falmouth are possible ports where mines could be installed. Falmouth is ruled out as it is not important enough.

The submarine warfare must be concentrated at all times against commercial traffic. For this reason, it was planned to send the commander of the U-Flotilla Wegener in U 53, so that later 2 groups could be formed under the respective tactical commands of the Senior Officers of the U-Flotillas Hundius and Wegener.

U 37 North Atlantic - AM 47 - U 38 North Atlantic - AL 37 - U 39 North Atlantic - AM 20 - U 40 North Atlantic - AM 01 - U 41 North Atlantic - AM 43.

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

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

"Fall Weiss".

On August 27, 1939 the OKM, Naval Operations (3rd Division) requested to confirm that the U-boats in the Atlantic have been informed that the encrypted memoranda in peacetime are still in effect, despite time X.

U 37 North Atlantic - AM 47 - U 38 North Atlantic - AL 95 - U 39 North Atlantic - AM 20 - U 40 North Atlantic - AM 48 - U 41 North Atlantic - AM 71

On August 28, 1939, the BdU concluded that at present, although all available submersibles are being used, there are not enough operational units and the time has come to reconsider the question of new construction. It is intended to request the Supreme Command of the Navy to do everything possible to accelerate the new construction.

In the afternoon the following information was radioed to the forces in the Atlantic:
German secret mobilization
Position of the English cruiser Ajax
Closing the Mediterranean to English merchant maritime traffic
British Admiralty control of English merchant traffic
Use of old and new grid charts.
Cipher material in wartime should not take effect, etc.

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

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

"Fall Weiss".

On August 29, 1939, the Atlantic U-boats received a detailed review of the political situation with the very secret message No. 5802 of the Naval War Staff (first division).

A very secret message No. 3812 was received from the Supreme Command of the Navy, on the subject of fuel and supplies. If the current state of emergency continues, the supply of dry supplies will be of prime importance. It is doubtful that this can be achieved in Spain. I consider it necessary to send these items there, either by air or by camouflaged ships.

The Supreme Command of the Navy has ordered that the fuel be transferred by funnel and 45 mm hose. At the moment the U-boats have 60 mm hoses. and fit for 90mm. As it is necessary to supply fuel overnight as fast as possible, hose with a diameter greater than 45 mm. must be provided.

U 37 North Atlantic - BE 8520 - 16:00 - Arrival at the operations area northwest of Porto (BE 8520); U 38 North Atlantic - BE 52 - In march towards the area of ​​operations; U 39 North Atlantic - AM 20 - In march towards the area of ​​operations, there are no special events; U 40 North Atlantic - BE 64 - In the area of ​​operations, there are no special events; U 41 North Atlantic - BE 55 - Eighth line broken by sea, hemp rope washed into the sea.

On August 30, 1939, the information sent to the U-boats on August 29 was incomplete to the extent that important reports on the darkening of ships and the diversion of ordinary maritime traffic routes were not transmitted by the OKM. Therefore, the U-boats were informed by the BdU via radio message T.O.O. 1305. The submersibles deployed in the Atlantic were informed of the departure of U 26, 27, 30 and 53 by radio message T.O.O. 1308.

U 37 Atlántico Norte - CF 3310 - 08:00 - Waiting position northwest of Porto, without special incidents (CF 3310); U 38 North Atlantic - BE 82 - In march towards the area of ​​operations, there are no special events; U 39 North Atlantic - AM 20 - In march towards the area of ​​operations, there are no special events; U 40 North Atlantic - BE 86 - In the area of ​​operations, there are no special events; U 41 North Atlantic - BE 57 / CF 26 - weather improvement. 09:30 - 16:00 exhaust valve repaired.

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

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

"Fall Weiss".

On August 31, 1939, the Supreme Command of the Navy (Kriegsmarine) informed the U-boats operating in the Atlantic about the situation in message TOO 1743.

1) Start of hostilities against Poland 0445/1/9.
2) The attitude of the Western powers uncertain.
3) Do not carry out attacks against English forces, etc., except in self-defense or by special order.
4) Units must remain in standby positions at present.

U 37 North Atlantic - CF 33 - Waiting position northwest of Porto, without special incidents; U 38 North Atlantic - CF 62 - Entry into the area of operations west of Porto, without special incidents; U 39 North Atlantic - AM 20 - In the area of operations, there are no special events; U 40 North Atlantic - CF 33 - In the area of operations, there are no special events; U 41 North Atlantic - CF 23 - Sailing on hold, without special events.

On September 1, 1939 the U-Flotilles "Weddingen" operating in the Baltic and "Saltzwedel", "Lohs", "Hundius" and "Wegener" operating in the Atlantic. U-boats deployed in the Atlantic will have to leave their respective areas of operations when their fuel reserves run out. The U-Flotilla "Hundius" will depart on September 19, arriving in port on October 3.

Dates can only be estimates. How long the U-boats will take when they return cannot be predicted. It will probably be around 3 weeks. There will therefore be a large gap from mid-September.

U 37 North Atlantic - CF 31 - Waiting position northwest of Porto, without special incidents; U 38 North Atlantic - CF 62 - In the area of ​​operations. On hold; U 39 North Atlantic - AM 16 - In the area of ​​operations. On hold.; U 40 North Atlantic - CF 8686 - In the area of ​​operations, there are no special events; U 41 North Atlantic - CF 58 - Underway to its holding position, no special events.

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

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

"Fall Weiss".

On September 2, 1939 Radio intelligence reports show that there is a concentration point for the steamers entering the Bristol Channel. This seems to indicate that there is no protection for the merchant traffic offshore. It is not possible to take the U-boats there yet, because on the orders of the Naval Warfare General Staff, they still cannot abandon their waiting positions.

U 37 North Atlantic - CF 31 - Waiting northwest of Porto. Part of the completely broken boat falls overboard. The use of the gun is questionable as no maintenance has been possible for a week; U 38 North Atlantic - CF 68 - In the area of ​​operations, there are no special events; U 39 North Atlantic - AM 16 - In the area of ​​operations. On hold; U 40 North Atlantic - CF 67 - In the area of ​​operations, there are no special events; U 41 North Atlantic - CF 8760 - 08:00 - Waiting west of Gibraltar (CF 8760). The crew bathes, two men each under a punctured fire hose.

War with Great Britain and France!

On September 3, 1939 at 12:56 p.m., the Naval High Command transmitted the following radio message to the forces operating in the Atlantic: hostilities with England, effective immediately. In order to avoid confusion with the radio message of August 31, the BdU sent the message TOO 1550: "start hostilities against England immediately, without waiting to be attacked first. In the radio message TOO 1400 the OKM ordered:" the U-boats must carry out the war against the merchant traffic, in accordance with the order of operations. "This should exclude any misunderstandings, since the order of operations expressly indicated to develop the actions against the merchant marine, in accordance with the current legislation.

The Naval High Command transmitted the following message to the ships in the Atlantic at 5:52 p.m.: "France is considered at war with Germany from 5:00 p.m. Do not take any hostile action against merchant ships for the present, except in self-defense." This order meant that, in the war against maritime traffic according to the prey law, French ships and cargo had to be released.

U 37 North Atlantic - CF 3269 - Waiting northwest of Porto (CF 3269). 12:30 pm - Receipt of the radio message: "Hostilities have begun". (Declaration of war of England); U 38 North Atlantic - CG 4950 - In the area of ​​operations. 12:00 - Reception of the radio message (CG 4950): "Hostilities have begun". (Declaration of war of England); U 39 Atlántico Norte - AM 16 - In the area of ​​operations. Receipt of the message "Hostilities have begun"; U 40 Atlántico Norte - CF 8686 - In operations area. 13:10 - Receipt of radio message (CF 8686): "Hostilities have begun". (Declaration of war of England); U-41 Atlántico Norte - CF 8874 - In operations area. 13:02 - Receipt of radio message (CF 8874): "Hostilities have begun". (Declaration of war of England). The inventory of provisions showed that there was enough food left for 40 days. Fuel 22.2 t.
