Convoy ON 7.

Convoy ON 7 departed Methill on 6 January 1940 for Norway where it was dissolved off Bergen on 9 January 1940.

It was made up of the following merchant ships;
Breda (Norwegian, 1260 GRT, built 1915), Briarwood (British, 4019 GRT, built 1930), Ingerois (Finnish, 1995 GRT, built 1909), Leda (Finnish, 1283 GRT, built 1908), Otto (Estonian, 1959 GRT, built 1918), Sally (Finnish, 2547 GRT, built 1896) and Vestra (British, 1141 GRT, built 1921).

Dowler, RN). HMS Khartoum departed from Scapa Flow on the 7th and it therefore appears that she joined the convoy at sea on the 7th. HMS Eskimo developed engine problems and was replaced by HMS Encounter (Lt.Cdr. E.V.St J. Morgan, RN), Encounter herself was relieved on the 8th by HMS Kandahar (Cdr. W.G.A. Robson, RN) which had departed Scapa Flow on that day.

1430A/28, sighted a merchant vessel thought to be Wangoni approaching from Lister. The vessel passed Triad at 1500 hours keeping well inside territorial waters. The vessel was now positively identified as Wangoni. She was painted light gray and had taken no steps to disguise herself. Triton continued to shadow Wangoni but she kept close inshore in territorial waters. Triton's speed was not sufficient to overtake her and eventually the chase had to be abandoned. (1)

8 Apr 1940 (position 57.40, 11.00)
At dawn, HMS Triton (Lt.Cdr. E.F. Pizey, RN) sighted four large trawlers approaching the Skaw from the south. These are thought to be German auxiliary A/S trawlers. They remained in the vicinity of the Skaw all day. Visibility was not good and they were difficult to identify through the periscope. HMS Triton patrolled a bit further to the south then intended to avoid them.

These were most likely auxiliary A/S trawlers from the 11th UJ flotilla of which six which were operating in the area at this time. These six were UJ-111, UJ-112, UJ-114, UJ-115, UJ-116 and UJ-176.

Later that day, HMS Triton fires a full salvo of ten bow torpedoes at the German heavy cruiser Blücher East of Skagen. However all torpedoes fired missed the target. Position was approximately 57°40'N, 11°00'E.

Blücher was the flagship of a force which was en-route to Oslo. This force was further made up of the heavy cruiser (pocket battleship) Lützow, Emden and the torpedo boats Albatros, Kondor and Möwe.

1650A/8, Sighted two heavy German warships approaching from the westward. Closed and started attack.

The leading ship was thought to be Gneisenau but it was not possible to get into an attack position for an attack on this ship. It was therefore decided to attack the second ship which was somewhat astern.

Shortly afterwards the leading ship changed course and now presented a better target then before. An attack was now started on the leading, more important, ship.

1758A/8, fired a full bow salvo of ten torpedoes (six internal and four external) from 7500 yards. Shortly after firing the Asdic reported that the target had increased speed from 14 to 20 knots. All torpedoes therefore missed astern. The attack was noticed by the Germans where torpedo tracks were seen around 1900B/8. [note time zone B= German (Berlin) time.] (1)

9 Apr 1940 (position 0.00, 0.00)
HMS Triton (Lt.Cdr. E.F. Pizey, RN) was still patrolling in the area near Skagen but now a little more to the south then on the previous day. The area was still heavily patrolled by enemy A/S vessels and aircraft. (1)

10 Apr 1940 (position 57.42, 10.46)
While operating in the Kattegat, HMS Triton (Lt.Cdr. E.F. Pizey, RN) attacked a German convoy made up of the transports Espana (7465 GRT, built 1922), Friedenau (5219 GRT, built 1920), Hamm (5874 GRT, built 1921), Scharhörn (2643 GRT, built 1927), Tucuman (4621 GRT, built 1918), Wigbert (3648 GRT, built 1921) of II.Seetransportstaffel and Antares (2593 GRT, built 1937), Itauri (6838 GRT, built 1923) and Muansa (5472 GRT, built 1911) from I.Seetransportsteffel. They were escorted by the old torpedo boats old torpedo boats T 107, T 108 and T 110 (it appears T 153 and T 155 also joined up but this may have been just after the attack), auxiliary submarine chasers UJ G, UJ H, UJ I and UJ K (13th UJ-Group) and the armed trawlers V 1501, V 1505, V 1506, V 1507, V 1508 and V 1509 (15 V-Flotilla).

A total of eleven transports of the II.Seetransportstaffel had sailed independently on 8 April from Gotenhafen (Gdynia) at various times so as not to reveal their true purpose as the invasion occurred only the next day and the escorts were disposed in the Kattegat at various focal points where a submarine attack could be expected. After the invasion was known some thirteen vessels began forming a convoy (including stragglers from I.Seetransportstaffel).

Five vessels of II.Seetransportstaffel were separated in the night of 9/10 April. These were Hanau (5892 GRT, built 1921), Kellerwald (5032 GRT, built 1923), Rosario (6079 GRT, built 1913) and Wandsbek (2388 GRT, built 1938) who proceeded independently some hours ahead of the convoy while Wolfram (3648 GRT, built 1921) appeared to have fallen behind. When she was attacked by HMS Sunfish the Hanua was thus proceeding alone.

During the attack on the convoy HMS Triton sank the transports Friedenau and Wigbert (3648 GRT, built 1921) and the auxiliary patrol vessel V 1507 / Rau 6 (356 GRT, built 1937) in position 57°27'N, 10°46'E.

1726A/10, fired 6 torpedoes from 2500 yards (the last on board). Four hits were heard. Triton went to 85 feet upon firing and turned stern on the convoy. Very shortly after the last torpedo explosion was heard depth charging started. For the next hour at least 78 depth charges were dropped of which the ones dropped about 5 minutes after the last torpedo hit were the closed. These shook Triton considerably but no serious damage was done.

2115A/10, surfaced at set course for home as Triton was now out of torpedoes. (1)

Barthes), Le Malin (Capitaine de Fregate (Cdr.) E.J.H.L. De Prez) and Le Triomphant (Capitaine de Fregate (Cdr.) M.M.P.L. Pothuau) (8e D.C.T. / Large Destroyer Division) returning at high speed from their raid in the Skagerrak (operation Rake). (1)

25 Apr 1940 (position 0.00, 0.00)
Around 2000A/25, a signal was received from the Vice-Admiral Submarines, timed 1719A/25, ordering HMS Triton (Lt.Cdr. E.F. Pizey, RN) to patrol off Stavanger. Course was set to the north-west to comply with this order not long afterwards. (1)

27 Apr 1940 (position 0.00, 0.00)
At 0110A/27, near position 58°45'N, 05°10'E, to the south-west of Stavanger, HMS Triton (Lt.Cdr. E.F. Pizey, RN) which was proceeding northwards, sighted an unidentified ship approaching from ahead. This ship appeared out of a hazy patch of horizon and there was only time to dive to avoid being sighted. The ship passed very close by and was heard on Asdics as being turbine engined and doing around 18 knots. It was thought to be some sort of escort vessel. (1)

0840A/23, surfaced and took of the boarding party.

The fishing vessel was the Danish Gadus of 20 tons from Thyboron. (1)

2 Jun 1940
Around 2230A/2, HMS Triton (Lt.Cdr. E.F. Pizey, DSO, RN) surfaced in position 57°41'N, 05°37'E after a days submerged patrol. Course was then set to return to Rosyth. (1)

3 Jun 1940 (position 57.00, 2.48)
HMS Triton (Lt.Cdr. E.F. Pizey, DSO, RN) and the German U-boat U-8 encountered each other in position 57°00'N, 02°48'E. The Germans thought the British submarine had fired a torpedo but this was not the case. Triton sighted a ship later thought to be a submarine. Nothing further happened.

0719A/3, in position 57°00'N, 02°48'E sighted a ship bearing 215°, distance about 6 to 8 nautical miles. Altered course towards. Lt.Cdr. Pizey thought it was either a trawler or a submarine. The contact was seen to alter course towards and disappear. This confirmed Lt.Cdr. Pizey's impression that it was a submarine and that it had dived.

0720A/3, dived and closed bearing. Listened for HE but could not hear anything.

U-8 reported that a torpedo was heard 20 seconds after she dived. (1)

4 Jun 1940

26 Jun 1940 (position 64.49, 10.03)
HMS Triton (Lt.Cdr. E.F. Pizey, DSO, RN) is detected and machine gunned by a German HE 115 aircraft in position 64°49'N, 10°03'E. Triton sustained no damage.

0133A/26, attacked by a German Heinkel 115 seaplane which approached from the cover of a black rain cloud. Triton was clearly silhouetted against a light northern sky. The German aircraft opened fire with her machine gun as Triton dived. Triton was not hit despite the close range of the aircraft.

Following this incident Triton proceeded to the North as it was thought her current location would now be more closely patrolled. (1)

HMS Triton (Lt.Cdr. E.F. Pizey, DSO, RN) encountered three enemy A/S vessels patrolling in her patrol area. HMS Triton tried to evade and proceeded to seawards to surface for a battery charge. The enemy A/S vessels however remained patrolling near her and HMS Triton was unable to surface to charge the battery and refresh the air inside the boat.

2330A/30, while still dived, in position 64°48'N, 10°07'E, sighted a small vessel crossing ahead from starboard.

0030A/1, another vessel was sighted on the port beam steering towards at slow speed. Shortly afterwards a second vessel was seen ahead crossing from port. Now considered these vessels to be an A/S group. One of them could be heard sweeping with echo.

0100A/1, Triton altered course to the north-west to escape from these A/S vessels as she was by now submerged for almost 24 hours and a battery charge and fresh air were needed. The trawlers were proceeding to the south-east. However around 0200A/1, there turned to the north-west and soon one was on either quarter of the submarine slowly overtaking. Lt.Cdr. Pizey decided to continue to run to the north-west expecting the trawlers to alter course back to the south-east later. They did so around 0420A/1.

0614A/1, Triton was now finally able to surface to charge and refresh the air inside the boat.

HMS Triton left the area soon afterwards to return to Rosyth. (1)

2 Jul 1940
HMS Triton (Lt.Cdr. E.F. Pizey, DSO, RN) is detected and bombed by a German HE 115 aircraft in position 63°12'N, 05°33'E. Triton sustained no damage.

0650A/2, in bad visibility sighted a Heinkel 115 aircraft flying straight towards Triton. Crash dived. When at 48 feet three bombs exploded astern. Triton was badly shaken but only minor damage was done. (1)

4 Jul 1940
Around 1515A/4, HMS Triton (Lt.Cdr. E.F. Pizey, DSO, RN) ended her 11th war patrol at Rosyth. (1)

20 Jul 1940
Shortly after 2000A/20, HMS Triton (Lt.Cdr. E.F. Pizey, DSO, RN) departed from Rosyth for her 12th war patrol. She was ordered to patrol off the South-West coast of Norway near Bergen.

For the daily and attack positions of HMS Triton during this patrol see the map below.

23 Jul 1940 (position 59.31, 4.13)
While on patrol off Bergen, Norway, HMS Triton (Lt.Cdr. E.F. Pizey, DSO, RN), sighted the conning tower of a submarine. An attack was not possible as contact was lost soon after sighting.

0800A/23, in position 59°31'N, 04°13'E sighted the conning tower of a submarine astern steering South. The conning tower only was visible from about half way up. Distance was at least 5 nautical miles. After Triton had turned round contact was soon lost. The conning tower had been in sight for about 10 minutes.

This was most likely German U-boat U-61 that was returning to Kiel from patrol. It had just made a brief stop at Bergen for fuel. (1)

29 Jul 1940 (position 60.00, 4.22)
HMS Triton (Lt.Cdr. E.F. Pizey, DSO, RN) sighted a submarine near Bergen, Norway. The submarine was too far off to be attacked. Besides that Lt.Cdr. Pizey though it might have been a British submarine.

0200A/29, in position 60°05'N, 04°22'E sighted a submarine steering between 290° and 310°. The submarine was sighted at a range of 3 to 5 nautical miles due to the fact that it was silhouetted against the Northern sky. Triton turned towards by the submarine was soon lost out of sight.

The submarine sighted might have been German U-boat U-62. (1)

2 Aug 1940
At 2226A/2, after a days submerged patrol, HMS Triton (Lt.Cdr. E.F. Pizey, DSO, RN) surfaced in position 60°01'N, 04°21'E after which she set course to return to Rosyth. (7)
