Hello to all :D; the early history of the Seventh.................................

U-Boot Type VII B of the U-Flotille Wegener.

War against the Western Allies. 1939.

September 3, 1939.

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:"U-boats must carry out the war against the merchant marine, 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 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."

Despite these messages, Kplt. Fritz-Julius Lemp, Commander of U 30, patrolling to the northeast of U 45 (the northernmost U-boat of the Unterseebootsflottille 'Wegener'), and to the west of Ireland, torpedoed and sank during the afternoon of this day the passenger ship Athenia (13,581 t), carrying 1,103 civilians to Canada (112 lives were lost, including 28 Americans). By the time the signal reached Gelhaar (U 45), Sohler (U 46), Prien (U 47) and Barten (U 52), their boats were in position on a reverse L-shaped line, watching over the approach routes to the British Isles. To the north and south, submersibles from other flotillas completed the blockade of the Atlantic, which stretched from Gibraltar to the north of Scotland.

U-45 North Atlantic - AL 85 - In the area of ​​operations. 12:26 - Radio message: "Beginning of hostilities." (Declaration of war of England). War according to current legislation. U 46 North Atlantic - BE 2450 - In the area of ​​operations. 13:10 - Radio message (BE 2450): "Beginning of hostilities". (Declaration of war of England). U 47 North Atlantic - BF 4942 - In the area of ​​operations. 13:20 - Radio message (BF 4942): "Beginning of hostilities." (Declaration of war of England). U 48 North Atlantic - BE 5930 - In the operations area, without special incidents. 17:17 - Radio message: "Declaration of war of the United Kingdom to Germany" (BE 5930). U 52 North Atlantic - BE 4632 - In the operations area, without special incidents. 12:28 - Radio message (BE 4632): "Hostilities against England begin". 17:38 - Radio message: "War between Germany and France". With no traffic, march to the northeast corner of the area of ​​operations. U 53 North Atlantic - AM 3191 - On the way to the operations area, without special incidents. 13:04 - radio message (AM 3191): "Start of hostilities." (England's declaration of war).

U-Boot Type VII B of the U-Flotille Wegener.

War against the Western Allies. 1939.

September 4, 1939.

Admiral Karl Dönitz told his collaborators: this war is very serious and you must bear in mind that it will be very long, maybe seven years and in the end we should be grateful if we at least get a draw! ... The Atlantic U-boats are informed of reported forces in their areas as they emerge. But the information is so inaccurate that it will have no practical use. Following the sinking of the passenger ship Athenia, OKM radio message to all submarines: "By order of the Führer, no hostile action should be taken for the time being against passenger ships, even if it is a convoy" .

U 45 North Atlantic - AL 88 - In the area of ​​operations, without special incidents. U 46 North Atlantic - BE 2450 - In the operations area, without special incidents. U 47 North Atlantic - BF 7318 / BF 7260 - 07:15 - The Greek steamer "MALIAKOS" stopped (BF 7318). No contraband. released. 13:30 - 18:10 - Two steamers chased to no avail (BF 7260). U 48 North Atlantic - BE 3760 - 14:22 - Immersion alarm. tanker in sight. 15:05 - to the surface. The ship is Swedish, the tanker "ABADAN". 3:50 pm - released. BE 6733 - 18:02 - Another tanker in sight. It wasn't stopped, too much swell. U 52 North Atlantic - BE 51 - In the area of ​​operations, without special incidents. U 53 North Atlantic - AL 3870 - On the way to the area of ​​operations. 10:03 PM - Submerged for 12 hours. Rest for the crew. 23:53 - Radio message: by order of the Führer, at the beginning, there are no offensive actions against passenger ships, even if sailing under escort.

Hello to all :D; the early history of the Seventh.................................

U-Boot Type VII B of the U-Flotille Wegener.

War against the Western Allies. 1939.

September 06, 1939.

Naval Operations Command issued the following radio message T.O.O. 1748: "The situation with France is still unclear. Hostile action must not be taken against French units, including merchant ships, except in self-defense. Merchant ships identified as French must not be detained. Avoid incidents with France at all costs." There are several radio intelligence reports that point to the introduction of the convoy system. Assembling's ports Milford and Plymouth.

The radio intelligence service has collected numerous submarine positions, mainly in the Bay of Biscay (U 47). Many of these are probably duplicates. If the war against merchant shipping is waged according to prize law, it is inevitable that the positions of the ships will be revealed. Obviously, there are many false reports showing that there is a widespread fear of U-boats.

U 45 North Atlantic - AL 97 - In the area of ​​operations, without special incidents.
U 46 North Atlantic - BE 31 - In the area of ​​operations, without special incidents.
U 47 North Atlantic - BE 6689 - 13:00 - Sighting of a steamer (BE 6689). 14:18 - I try to stop the steamer with the flag signal. Steamer transmits. Shot off the bow. Steamer continues to emit. Three shots on the bridge. The steamer stops. The crew enters the boats. 14:40 - Torpedo against steamer. Results. The British ship RIO CLARO was sunk.
U 48 North Atlantic - BE 56 - In the area of ​​operations, without special incidents.
U 52 North Atlantic - BE 81 - In the area of ​​operations, without special incidents.
U 53 North Atlantic - AL 2942 - 17:30 - 18:30 - Deep dive test. Immersion at 100 m. All good.

Hello to all :D; the early history of the Seventh.................................

U-Boot Type VII B of the U-Flotille Wegener.

War against the Western Allies. 1939.

September 7, 1939.

Withdrawal of the Atlantic U-boats: The first thing to decide is whether the Atlantic Submersibles will operate against merchant shipping or against English naval forces. True success against naval forces can only be expected by luring ships from harbors out into the open sea. Our surface forces are so weak that they can barely accomplish this. Therefore, it was decided, in accordance with my proposal, to continue to use the submersibles against commercial traffic.

It should be assumed that the traffic will increase again in early October. Therefore, it was proposed to bring back the "Hundius" and "Wegener" U-Flotillas and the proposal was approved by the Naval Warfare Staff. The order was given in the radio message 1902/7/9.

U 45 North Atlantic - AL 97 - In the area of ​​operations. Received radio message: Return at the highest speed possible. Return sail started.
U 46 North Atlantic - BE 2410 - In the area of ​​operations. Received radio message: Return at the highest speed possible. Return sail started.
U 47 North Atlantic - BF 4118 / BE 6688 - 16:57 - Steamship sighted (BF 4118). Approach to the target. 17:47 - Surfaced. The steamer emitting SOS. After three shots the ship stops. The crew enters the boats. The steamer is still halfway through. Several shots above the waterline. 18:15 - Torpedo against steamer. It doesn't detonate. Second torpedo, running. 18:30 - Steamer sunk with artillery. The British ship GARTAVON (*) was sunk. 21:30 - Radio message received: starting return march (BE 6688). The return march began.
U 48 North Atlantic - BE 52 - 20:55 - Radio message received: initiate return march. The return march began.
U 52 North Atlantic - BE 7395 - 22:00 - Radio message received: initiate return march. The return march began.
U 53 North Atlantic - AL 54 - Navigating towards the area of ​​operations, without special incidents.

(*) The British ore freighter GARTAVON (1,777 TPB) was sunk by artillery fire. The entire crew of the steamer, which was loaded with 1,600 tons of iron ore and 500 tons of asphalt and general cargo, survived the sinking.

September 11, 1939.

Radio intelligence report stated 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, since no submarines have appeared in this area so far (victim of U 48).

Hello to all :D; the early history of the Seventh.................................

U-Boot Type VII B of the U-Flotille Wegener.

War against the Western Allies. 1939.

September 13, 1939.

Radio message to submarines in the Atlantic, informing them of warning of traffic along the Dungeness - Downs line and mines in the vicinity of the lightship St. Catherine. Now that the Hundius and Wegener U flotillas have departed, U 53 will operate in Area B. Revised smuggling list received in secret message 6035 from Naval Operations Command Staff. An excerpt was transmitted to submersibles in the Atlantic.

U 45 North Sea - AN 27 - On the way back, no special events.
U 46 North Sea - AN 43 - On the way back, no special events.
U 47 North Sea - AN 35 - On the way back, no special events.
U 48 North Sea - AF 7830 - 18:50 - Neutral steamer in sight. She was not stop.
U 52 North Sea - AF 79 - On the way back, no special events.
U 53 North Atlantic - BE 2280 - 18:20 - Large passenger ship sighted. She sails at high speed to be intercepted. BE 3267 - 23:55 - steamer with position lights sighted. The chase begins.

September 14, 1939.

Analysis of the known sinkings through radio intelligence shows that most of them were in the area of ​​U 29. Therefore, a radio message was sent at 09:30 hours to U 55 (Note: ¿U 53?): "The extension to the area of ​​operations seems promising and is recommended."

Conference with the Admiral Superintendent of Maintenance on the situation of the torpedoes. The department had stated that all G7e's delivered were adapted for angled firing. The U-boats were informed accordingly on Sep 7. Then, on the afternoon of the 13th, maintenance informed us that gyroscopic equipment had been installed, but the queues had not adapted. These errors should not occur. Whether this has caused glitches remains to be seen.

U 45 Baltic Sea - AO 4445 - On her way back. Steamer sighted and stopped. She is the Swedish HOLLANDIA. No contraband. Released. AO 4418 - The Norwegian steamer SKUM stopped. Released.
U 46 North Sea / Baltic Sea - AN 36 - On her way back. AO 7185 - 23:10 - Encounter with U 19. Signal change detection.

War against the Western Allies. 1939.

September 15, 1939.

U 31 reported by radio message at 07:00 about a convoy out of the Bristol Channel. This is the first clear report of a convoy. U-boats in neighboring areas U 34, 29, 53, should now operate against it, they may be lucky.

Over the course of the day U 46, 47 entered Kiel. U 47 reports that she has sunk:
H.H. Bosnia 2407 BRT 3,200 tons of sulfur
Rio Claro 4086 BRT 4,777 tons of mixed cargo
Gartavon 1777 BRT 2,900 tons of ore

The submersible was in her area of ​​operations for 4 days (3-7.9) after the outbreak of the war. A very good start. U 46 unsuccessful - bad luck. Towards evening, U 45 entered Kiel. Unsuccessful, as her position appears to have been outside of areas frequented by shipping traffic.

U 45 Baltic Sea / Kiel - AO 77 - 17:03 - Arrival in Kiel. Finishing of the 1st Patrol.
U 46 Baltic Sea / Kiel - AO 74 / AO 77 - 08:30 - Arrival in Kiel. Finishing of the 1st Patrol.
U 47 Baltic Sea / Kiel - AO 77 - 00:14 - Arrival in Kiel. Finishing of the 1st Patrol.
U 48 Baltic Sea - AO 4813 - 22:55 - British submarine sighted on the way back. 22:58 - The torpedo shot missed. 23:00 - the submersible went to dive and disappeared.
U 52 North Sea - AN 3538 - On her way back. 12:00 - Sailing the Skagerrak and the Little Belt to Kiel.
U 53 North Atlantic - BE 3261 - 14:20 - Steamer sighted. On parallel course. 14:49 - Vapor tries to be stopped with a shot. Without reaction. 14:59 - Shot off the bow. No reaction, automatic fire. 15:20 - The ship stops. The crew goes to the boats. 15:44 - Torpedo over the ship. Impact, she does not sink. 15:50 - Second torpedo. Impact.

The British tanker CHEYENNE was sunk. 18:54 - A destroyer fires twice at the U-boat. 18:55 - Dive alarm. 19:10 - Two - three depth charges at 100 m. No damage. Six men of the crew of the tanker loaded with 12,600 t of fuel lose their lives, 37 men are able to get off the ship without injury and are later rescued (BE 3261/50°20'N – 13°30'W). The wreck of the ship was eventually sunk a little later by a British destroyer. After the sinking, U 53 supplies hot tea to the survivors.

Hello to all :D; the early history of the Seventh.................................

U-Boot Type VII B of the U-Flotille Wegener.

War against the Western Allies. 1939.

September 16, 1939.

September 16, 1939.

U 48 and U 52 entered the port. Successes:

U 48 S.S. Winkleigh 5,055 tons; S.S. Royal Scepter 4,053 tons; S.S. Firby 4,869 tons. Total: 14,977 tons.
U 52 sank an Appalachee type ship, 8,826 tons.

U 48 Baltic Sea - AO 71 - 02:04 - German submarine in sight. 19:20 - sailing through the Kleinen Belt at full speed.
U 52 Baltic Sea - AO 71 - On the way back, no special events.
U 53 North Atlantic - BE 3131 - 12:30 - Steamer sighted. She is the neutral COLD HABOR. 18:45 - Steamer sighted. Seen in immersion. 19:12 - Shot off the bow. The steamer stops, bring papers. She is the Norwegian ÖRNEFJELL. No contraband. She continued.

September 17, 1939.

The Naval Warfare Staff decides to accelerate the investigation of the causes of the increase in the failure of the submarine torpedoes G7e and G7a. In addition to military disadvantages, attention is drawn to the psychological strain on submarine crews. A loss of crew confidence in their weapons is said to be highly undesirable.

U 48 Baltic Sea / Kiel - AO 77 - 05:50 - Arrival in Kiel. Finishing of the 1st patrol. The U-boat spent 30 days at sea and sank three British merchant ships totaling 14,777 GRT. U 48 is docked at KIEL for overhaul.

U 52 Baltic Sea / Kiel - AO 77 - 13:00 - Arrival in Kiel. Finishing of the 1st patrol. Kplt. WOLFGANG BARTEN hands over command of U 52, no word on his successor for the next two months. U 52 returned from her first mission to KIEL. The U-boat was at sea for 30 days. In KIEL it is planned to modernize and repair it. After her stay in the shipyard, sand was detected in the lubricating oil, presumably an act of sabotage, which forced the submersible to return to the dock.

U 53 North Atlantic - BE 2384 - 06:52 - Steamer sighted. sailing to the place. 08:03 - Second steamer sighted. operating. 14:40 - Surfaced at about 5,000 m in front of the steamer. Three warning shots were fired. The steamer emits. She lowers boats. 15:42 - Torpedo against steamer fails. 15:55 - Second torpedo. Impact. Steamer does not sink. 16:14 - shot. Impact. British steamer SS Kafiristan of 5,193 GRT and loaded with 8,870 tons of sugar sunk (8 dead and 29 survivors). 16:26 - Surfaced for rescue. On scene great American steamer. She saves the survivors. 17:00 - Dive by air alarm (4 Swordfish from HMS Courageous). No damage. 19:00 - 19:30 - Two bombs in the wake, far away.

Hello to all :D; the early history of the Seventh.................................

U-Boot Type VII B of the U-Flotille Wegener.

War against the Western Allies. 1939.

September 18, 1939.

British radio announced the sinking of the aircraft carrier Courageous (22,500 tons) by a submarine. A wonderful success. Several radio intelligence reports received during the last week clearly show that the enemy is introducing the convoy systems in the Mediterranean. Reports from agents point to English troop transports leaving for France from Channel ports.

Improper torpedo behavior is causing serious concern. The G7a and G7e torpedoes have repeatedly exploded after a run of about 250 meters, before reaching the target.

Around noon, the Naval High Command arrived at the group's headquarters. He asked about the process of submarine warfare and raised the question of sending submarines to the Mediterranean. In my opinion, it would not be good, with the few submarines currently available, to divide them into too many theaters of war.

U-53 North Atlantic - BE 23 - In the area of ​​operations, there are no special events.
