5 Dec 1939
At 2302 hours HMS Trident (Cdr. J.G. Gould, RN) sights a submarine bearing 120° 600 yards steering 250°. Trident turned toward and all bow tubes were flooded. Identification signals were made by the submarine but could not be read. It was decided that it was probably a friendly submarine that was out of position due to the bad weather that prevented good sights to establish position. The submarine eventually turned out to be HMS Sunfish (Lt.Cdr. J.E. Slaughter, RN).

Returning later to stop in a position 155° Delgada Lighthouse 2 nautical miles.

0748 hours - Closed the vessel to question her. At intervals between 0815 and 0850 hours she was signalled, in plain language, "what ship" and "sent boat with ship's papers". The vessel tried to keep astern of Trident at all times and at 0845 hours made for the harbour entrance. A warning shot was now fired across her bows that stopped her temporarily. A signal was now sent "Abandon ship i will sink you in five minutes. This resulted in the ship getting underway again. A second shot was now fired across her bows but to no effect.

1103 hours - In position 71°01'N, 24°24'E fired two torpedoes from 650 yards at a 2500 tons merchant vessel. The attack drill did not went as it should have resulting in the torpedoes to miss the target.

1106 hours - Surfaced for gun action. The enemy immediately altered course. 21 rounds were fired for at least 5 hits before the enemy went out of sight. The enemy could not be followed as fire was now opened by shore batteries, the ship was making good speed and Trident would have the enter the fjord to deep with the danger of not being able to reach open water if she was counter-attacked. The attack was therefore broken off.

According to German sources 6 Norwegians were killed and one German was wounded.

21 Aug 1941
HMS Trident (Cdr. G.M. Sladen, DSC, RN) attacked the German minelayer Bremse in Lopphavett with four torpedoes in position 70°12'N, 21°05'E. No hits were obtained.

22 Aug 1941
HMS Trident (Cdr. G.M. Sladen, DSC, RN) torpedoed and sank the German merchant Ostpreu?en (3030 GRT, built 1920) in the Kvaenangenfjord, Norway in position 70°12'N, 21°05'E.

(All times are zone -3)
1527 hours - Sighted a convoy of 4 ships escorted by 2 trawlers. The convoy appeared to be in 2 lines. The German Ostpreu?en was leading ship of the nearer line and had one of the trawlers ahead of her and what is thought to be a Norwegian merchant astern.

1600 hours - Fired five torpedoes from 600 yards against the Ostpreu?en resulting in three hits.

1604 hours - Saw the trawlers closing. During the next 1,5 hours 9 depth charges were dropped but none were close.

1730 hours - Sound from the trawlers had disappeared so went to periscope depth.

1800 hours - Proceeded to seaward while still submerged.

The convoy was made up of the German Ostpreu?en, Barcelona (3101 GRT, built 1921), Barmbeck (2446 GRT, built 1929) and Sivas (3831 GRT, built 1928). They were escorted by the German armed trawlers Franke (former HMS Larwood) and Nordkap.

30 Aug 1941
HMS Trident (Cdr. G.M. Sladen, DSC, RN) torpedoed and sank the German merchants Donau II (2931 GRT, built 1939) and Bahia Laura (8561 GRT, built 1918) in Lopphavet, Norway in position 70°35'N, 21°45'E.

(All times are zone -3)
1740 hours - Sighted the leading ships of a convoy to the West of Silden heading North. The convoy was soon seen to be made up of four ships in line ahead. They were escorted by two large destroyers and three trawlers and one He 115 aircraft overhead. Quite a strong escort so it was most likely a very valuable convoy. Commenced attack. The second ship was selected as the main target but as Lt.Cdr. Sladen had only two torpedoes left he decided to aim them individually at the second and third ship. During the setup for the attack the targets were shifted to the first and second ships. Also one of the destroyer passed very close by but Trident was not detected.

1814 hours - Fired the last two torpedoes against the selected ships from 700 yards. Both torpedoes were hits. The first hit after 48 seconds on a 1500 tons ship, the second after 50 seconds on a 3000 tons ships. Immediately after firing course was altered to seaward and speed was increased. During the next 2 hours and 15 minutes 56 depth charges were dropped. The first 45 of these were unpleasantly close.

2030 hours - Came to periscope depth. The only ships in sight were the full escort of the two destroyers and three trawlers, one merchant that appeared undamaged and one merchant stopped badly listed and with a large column of smoke rising from her. By her appearance this was the second ship fired at. As the aircraft was seen still searching Trident was taken to 70 feet and continued to seaward.

This convoy was made up besides the two ships given above and the German merchants August Bolten (3665 GRT, built 1937) and Cornouaille (3303 GRT, built 1928). They were escorted by the German destroyers Z 10 / Hans Lody and Z 20 / Karl Galster and the German armed trawlers UJ 1708, Gote and Franke. The armed trawlers UJ 1706 and UJ 1707 made an AS sweep ahead of the convoy.

3 Sep 1941
While returning to base at Polyarnoe, Russia, HMS Trident (Cdr. G.M. Sladen, DSC, RN) is fired upon but missed by German U-boat U-566. The U-boat was spotted by Trident in position 69°59'N, 35°00'E but could not be attacked with torpedoes as there were none left aboard. It was not observed on board Trident that she was fired upon.

About six hours later Trident arrived at Polyarnoe ending her 19th war patrol.

Sladen was under the impression that it was sinking. Trident proceeded to the seaward as Cdr. Sladen did not want to dive again until he was in open water because both the gyro and magnetic compass were damaged in the depth charge attack.

30 Sep 1941
HMS Trident (Cdr. G.M. Sladen, DSC, RN) fires three torpedoes against the German hospital ship Birka (1000 GRT, built 1937) in the Breidsundet about 4 nautical miles north-west of Hav?ysund, Norway in position 71°03'N, 24°34'E. All three torpedoes missed their target but only just missed the escorting R-boat R-154.

(All times are zone -3)
0945 hours - Sighted a merchant vessel of about 4000 tons rounding Gavloden Point Westwards. It was escorted by two R-boats.

1001 hours - Fired three torpedoes from 7000 yards. No hits were obtained. One of the R-boats dropped two depth charges a long way off. Trident now retired seawards to return to base.

This convoy was made up of the vessels mentioned above. German sources only mention the R-154 as escort.

3 Nov 1941
During the second of two attacks on the same convoy HMS Trident (Cdr. G.M. Sladen, DSC, RN) torpedoed and sank the German auxiliary submarine chaser UJ 1213 / Rau IV (354 GRT, built 1937) in the Porsangerfjord in position 70°58'N, 26°08'E. The German merchant Altkirch (4713 GRT, built 1928) is missed in the first attack on this convoy.

(All times are zone -3)
In position 70°56'N, 26°10'E sighted a widely dispersed eastbound convoy with an escort of four trawlers. One ship, of 2000 tons, was close by, the rest was further away. The actual number of ships was impossible to distinguish as the ships were against the land and the periscope was continually being washed over.

0924 hours - Fired three torpedoes from 2500 yards at the closest merchant ship.

0929 hours - One torpedo was heard to hit. When the periscope was put up it was noted that the convoy was in confusion, ships were steering anywhere, but the ship fired at seemed unharmed. Shortly afterwards a few depth charges were dropped at random.

0938 hours - Further study of the situation was interfered with as one ship (of 2000 tons) was seen to be going to pass close by. At first it was thought to be the initial target but this was later seen to be not the case.

0947 hours - Fired two torpedoes from 1000 yards. 50 Seconds later an explosion was heard thought to be a torpedo hitting giving a running range of 780 yards. This explosion was quite different from the three other explosions heard shortly afterwards and to previous ones. Through the periscope the vessel appeared to be intact. During one look Cdr. Sladen thought she was settling by the stern but she was seen to be still afloat 10 minutes later. Trident now retired from the area.

According to German sources this convoy was made up of the following ships; German merchants Altkirch (4713 GRT, built 1928) and the Norwegian merchants (both in German control) Fjeld (2960 GRT, built 1916), Kl?veren (428 GRT, built 1938). They were escorted by the German armed trawlers Rabe, Nordkap, Nordwind, UJ 1213 and UJ 1403.

4 Nov 1941
HMS Trident (Cdr. G.M. Sladen, DSC, RN) attacks a convoy off the Porsangerfjord in position 71°05N, 26°51E. Four torpedoes were fired but no hits were obtained.

(All times are zone -3)
0945 hours - In position 71°05'N, 26°55'E sighted a convoy of three 3000/4000 tons merchant ships escorted by three M-class minesweepers. Started attack.

0951 hours - Trident had now penetrated the screen of the convoy.

1000 hours - One of the minesweepers turned towards and appeared to be in contact. Cdr. Sladen broke off the attack and altered course at full speed. The minesweeper dropped 20 depth charges in the next four minutes that shook Trident considerably. Trident retired from the scene.

1221 hours - In position 71°05N, 26°51E sighted masts bearing 202°.

1245 hours - Saw that this was yesterday's convoy, four merchant ships and a number of trawlers. Also noted that it was headed by the ship we thought we had sunk yesterday. We must have hit something else (Cdr. Sladen was correct in this).

1312 hours - Fired four torpedoes at a 2500 tons ship from 6000 yards. No hits were obtained. Trident altered course to the seaward after the attack.

The first attack, the one that was spoiled, was against a convoy made up of the German merchants (4117 GRT, built 1927 and Graciella (no details found) and the Danish merchants (in German service) Schillighorn (2864 GRT, built 1918) and Utlandshorn (2642 GRT, built 1928). They were escorted by the German minesweepers M 15, M 17, M 22, M 29 and M 30.

The second attack was against the same convoy attacked the previous day, this time escorted by 'only' Rabe, Nordkap and Nordwind.

7 Nov 1941
HMS Trident (Cdr. G.M. Sladen, DSC, RN) fires three torpedoes against the German minesweeper depot ship MRS 3 / Bali north of the Laksefjorden in position 71°06'N, 26°57'E. The torpedoes missed their target.

(All times are zone -3)
0240 hours - Sighted one merchant ship escorted by two trawlers approaching from the Westward.

0321 hours - Fired three torpedoes from 6500 yards.

0327 hours - The target was seen to alter course away and shortly afterwards an explosion was heard. Possibly she turned away to beach herself.

According to German sources this convoy was made up of the R-boat tender MRS 3 / Bali escorted by the armed trawlers UJ 1205 and UJ 1706. The target was not hit but missed.

23 Feb 1942
HMS Trident (Cdr. G.M. Sladen, DSO, DSC, RN) fires three torpedoes (7 was intended but only three were fired due to a failure in drill) against the German heavy cruisers Prinz Eugen and Admiral Scheer west of Kristiansund, Norway in position 63°12'N, 07°00'E. Prinz Eugen is hit in the stern with one torpedo but Admiral Scheer is missed.

0551 hours - Sighted dim shape bearing 252°.

Soon it was seen that there were two large vessels escorted by three destroyers, one ahead and one on either beam. Before firing torpedoes it was seen that the leading ship was a pocket battleship and the other one was a cruiser. Decided to fire a salvo of seven torpedoes. The six internal bow torpedo tubes and no.8 external.

0602 hours - In position 63°12'N, 07°00'E fired the first torpedo from 2000 yards and after firing the third gave the order to dive as not to be spotted by the nearest destroyer. As Cdr. Sladen shut the hatch the first explosion was heard. A second explosion was heard half a minute later. On getting below Cdr. Sladen saw that the 'stop fire' light was burning and that the rating who works the order instrument had put on 'stop' on the order 'dive'. This was not noted by any officer as they were all busy with taking the boat below. By the time it was noticed by Cdr. Sladen only three torpedoes of the intended seven were fired and it would have been a waste of four torpedoes to fire the remainder of the salvo.

0607 hours - The HE of one of the vessels was heard to slow down and then cease.

0609 hours - HE of one of the destroyers came nearer but soon faded out.

0640 hours - After nothing was heard for a while Trident surfaced and an enemy report was passed.

The Admiral Scheer and Prinz Eugen were at the time of the attack escorted by only two destroyers. These were Z 7 / Hermann Schoemann and Z 25. The Z 4 / Richard Beitzen, Z 5 / Paul Jacobi and Z 14 / Friedrich Ihn had lost contact with the other ships in bad visibility.

6 Jul 1942
HMS Trident (Lt. A.R. Hezlet, DSC, RN) encounters two German U-boats in position 72°07'N, 31°09'E. They were not attacked (see below for the reasons).
These two U-boats were most likely the U-334 and U-456.

(All time are zone -2)
0925 hours - While submerged in position 72°07'N, 31°09'E the officer of the watch sighted two objects to the Northward. The objects were distorted by mirage and could not be identified. As they might well have been tops of the German heavy units thought to be in the area they were closed at full submerged speed for five minutes until it was seen that they were two German U-boats. Their course and speed was 195° and 8 knots. They passed 2300 yards ahead of Trident.

They were not attacked for the following reasons (in order of importance)
1) It was thought they German heavy units were to the Eastward about to attack the scattered convoy PQ 17. Trident was well placed to intercept them on their return.
2) The patrol orders stated that a full salvo had to be retained for these German heavy units. Therefore only 4 at max. could be fired as two torpedoes were already expended during the scuttling of the American merchant Alamar on 27 May. If a salvo of 10 torpedoes was to be retained four out of the six C.C.R. (magnetic) pistols would have to be expended.
3) The U-boats were homeward bound and therefore no longer a menace to the convoy.
4) We were instructed by signal not to attack submarines to the West of 30'E. Despite the fact that Trident was to the East of 30'E the order was clearly meant to apply.
