History

HMS Trooper (Lt. John Somerton Wraith, DSO, DSC, RN) sailed from Beirut on 26 September 1943 for a patrol in the Aegean Sea off the Dodecanese islands, including the Leros area. She failed to return on 17th October and was reported overdue on that day. She is presumed lost on German mines East of Leros. The exact date of her loss is not known. It must have been between 14 and 17 October.

However the Germans claim that HMS Trooper was sunk by Q-ship GA.45 on 15 October 1943. But this claim to have sunk Trooper is erroneous. GA-45 carried out an attack on a submarine 2.5 miles south of Kalymnos on 15th October. The Germans were unaware of the identity of the submarine or whether it had been destroyed. The attack was made initially with depth charges, then when the submarine surfaced with gunfire. The submarine in question was HMS Torbay and she was not damaged during this encounter.

HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) is warned (in a signal timed 1134A/6, from Capt. S 8) about a convoy to the North-West of her. In the afternoon she is able to sight this convoy about 8 nautical miles away despite the rain (no position given in the patrol report but most likely well to the north-east of Ustica). HMS Trooper tries to get into an attack position but is unable to do so, the range is just to great and the convoy slips by.

The convoy HMS Trooper was ordered to try to intercept was made up of the transports Ines Corrado (8016 GRT, built 1942), Balzac (German (former French and before that British), 1947 GRT, built 1928) and Henri Estier (German (former French), 1984 GRT, built 1930).

Around 0830C/28, HMS Trooper (Lt. G.S.C. Clarabut, RN) arrived at Port Said and is immediately docked in the floating dock. (10)

6 Jul 1943
HMS Trooper (Lt. G.S.C. Clarabut, RN) is undocked. (11)

7 Jul 1943
Around 1930C/7, HMS Trooper (Lt. G.S.C. Clarabut, RN) departed from Port Said for her 6th war patrol. She was ordered to patrol in the Adriatic and off the West coast of Greece.

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

12 Jul 1943
At 0604C/12, HMS Trooper (Lt. G.S.C. Clarabut, RN) sighted a small tranport of about 800 tons escorted by an Abba-class torpedo boat hugging the coast of Levkas Island. Their course was southward 190°. They could not be attacked due to the range. (6)

14 Jul 1943
HMS Trooper (Lt. G.S.C. Clarabut, RN) attacks the Italian merchant Cherso (1756 GRT, built 1912) with torpedoes and gunfire off Cape Rodoni near Durazzo, Albania. Cherso was unescorted and in ballast. She was proceeding to San Giovanni di Medua (Albania). Cherso replied with gunfire and escaped without damage. The Italian torpedo-boat Giuseppe Missori and aircraft from Aeroalbania were ordered to hunt the submarine but although sighted by Trooper, she managed to elude them.

0800C/14 - When in position 42°22'N, 18°17'E, sighted a 2000 tons transport proceeding north from Durazzo. Started attack.

0831C/14 - Fired three torpedoes from 3400 yards. All torpedoes missed.

0837C/14 - Surfaced for gun action, range 5400 yards. Fired 8 rounds for 1 hit that put the gun of the target out of action.

0839C/14 - Sighted an aircraft so broke off the action and dived. This was most unfortunate as a second transport had just been sighted to the northeast. This transport was southbound. (6)

15 Jul 1943
At 0820C/15, in approximate position 42°30'N, 18°17'E, HMS Trooper (Lt. G.S.C. Clarabut, RN) sighted a small passenger vessel thought to be either the Yugoslavian Bakar (now in Italian service named Buccari, 334 GRT, built 1931) or Rab (now in Italian service named Arbe, 344 GRT, built 1931). The ship was northbound, 330° and was hugging the coast. She was not attacked. The ship sighted was probably the Dubrovnik (Italian (former Yugoslavian), 996 GRT, 1909) who sailed from Kotor at 0600B/15 and arrived at Gravosa at 0930B/15.

At 1230C/15, in approximate position 42°24'N, 18°17'E, a convoy off smaller vessels was sighted proceeding southwards. It was seen to be made up of a tug towing a floating crane. Escort was provided by what was thought to be the former Yuguslav minesweeper D 2 and two other small craft thought to be Italian RD-class minesweepers. Also an air escort was seen overhead. Their speed of advance was 4 knots. They were not attacked as nothing seemed to have sufficient draught to warrant a torpedo.

At 1610C/15, a small transport of about 400 tons was seen proceeding northwards. She was in ballast which made her too shallow draught to be attacked with a torpedo.

According to Italian sources seventeen Italian vessels took part in an operation (against partisans ?) from 10 to 20 July 1943 and the ships sighted in the afternoon perhaps belonged to them.

16 Jul 1943
At 1315C/16, in approximate position 42°27'N, 18°21'E, HMS Trooper (Lt. G.S.C. Clarabut, RN) sighted a small 600 tons transport proceeding northwards. She was in ballast. She had an air escort overhead. She was not attacked.

At 1420C/16, a signal was received from Capt. S.10 (timed 0630B/16) ordering Trooper to leave her patrol area and to proceed to the Gulf of Taranto. Trooper immediately set course to clear the coast as she was to make a run of 230 miles in 30 hours. (6)

18 Jul 1943
At 0151C/18, HMS Trooper (Lt. G.S.C. Clarabut, RN) received Capt. S.10's signal timed 2241B/17, ordering her to be in position 8 miles south of Cape Santa Maria di Leuca between 0200 and 1200B/20. (6)

20 Jul 1943
At 0312C/20, HMS Trooper (Lt. G.S.C. Clarabut, RN) sighted a dark object astern on an approximate course of 320°. Range was about 4000 yards. It was at first thought this was a destroyer.

At 0315C/20, HMS Trooper dived. The dark object zigged to starboard and was then seen to be a large submarine. Two Italian submarines arrived at Taranto that morning, Onice coming from Leros and Pietro Micca returning from a short patrol. Given the position the enemy submarine was sighted it seems likely it was the Onice.

At 0336C/20, HMS Trooper surfaced to give chase but the target was out of sight and was not seen again.

At 0915C/20, HMS Trooper, now on submerged patrol, sighted a small A/S vessel patrolling off Cape Santa Maria di Leuca. Also an aircraft was seen to be patrolling the area. This was perhaps the tug Talamone who had sailed from Otranto for minesweeping duties at 0720B/20 and returned at 1145B/20 or the fishing vessel San Giuseppe who sailed from Otranto at 0600B/20 for Gallipoli.

At 1140C/20, in approximate position 39°42'N, 18°26'E, a vessel was seen coming towards at a range of 500 yards. An aircraft was seen to be patrolling overhead. HMS Trooper dived to 120 feet and turned stern on. She returned to periscope depth half an hour later to find nothing in sight. This was possibly the transport Citta di Alessandria (Italian, 2498 GRT, built 1930) who left Bari at 1900B/19 for Taranto at 7.5 knots and arrived at Taranto at 1930B/20.

At 2020C/20, in approximate position 39°38'N, 18°09'E, a transport escorted by an aircraft was sighted inshore to the northward. Most likely two escorts were also present. Range was about 12 nautical miles so an attack was out of the question. This was possibly the minelayer Barletta and auxiliary Morosini on passage from Corfu (sailed at 1107B/20) to Taranto (arrived at 0041B/2). (6)

22 Jul 1943
At 0257C/22, when in position 215° - Cape Santa Maria di Leuca lighthouse - 30 nautical miles, HMS Trooper (Lt. G.S.C. Clarabut, RN) sighted a dark object down moon. As periscope visibility was good she dived to attack. The object was subsequently identified as a submarine on course 210° and resembled a British T-class boat. The attack was then broken off as HMS Trooper was close to the area where HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) was to operate. It was later established that the submarine sighted was indeed HMS Tactician.

Earlier, at 0115C/22, Capt. S.10's signal timed 1512B/21, was received ordering HMS Trooper to patrol to an area with a radius of 10 miles from position 39°17'N, 17°22'E (south-east of Punta Alica) by 0800B/23. (6)

23 Jul 1943
At 0735C/23, HMS Trooper (Lt. G.S.C. Clarabut, RN) sighted two schooners patrolling near Alice Point. These were most likely auxiliary A/S schooners. A/S schooner patrols would be seen near Alice Point also on the 24th and 25th.

At 1053C/23, a Spica-class torpedo boat was seen doing an A/S sweep. She approached from the north and was proceeding on a southerly course while using her Asdic. She appeared to be in contact briefly and then stopped for about 10 minutes before she restarted and made off on course 190°.

At 2245C/23, Capt. S.10's signal timed 0957B/23, which ordered Trooper to leave patrol PM on the 26th. (6)

26 Jul 1943
At 2206C/26, HMS Trooper (Lt. G.S.C. Clarabut, RN) surfaced in position 110° - Cape Colonne - 10 nautical miles and then set course to leave patrol.

However at 2250C/26, a signal was received from Capt. S.10 timed 2116B/26, ordering Trooper to return to patrol as the two Italian battleships in Taranto may have left. (6)

27 Jul 1943
At 1805C/27, HMS Trooper (Lt. G.S.C. Clarabut, RN) received a signal from Capt. S.10 timed 1155B/27, ordering Trooper to patrol in an area with a radius of 7 miles from position 39°43'N, 18°01'E. Course was set accordingly.

At 2210C/27, a signal from Capt. S.10 timed 1155B/27 was received which ordered HMS Trooper to leave patrol at 0600B/29. (6)

29 Jul 1943
The Italian submarine Pietro Micca was torpedoed and sunk at the entrance to Adriatic, south of the Strait of Otranto in position 39°45'N, 18°17'E by the British submarine HMS Trooper (Lt. G.S.C. Clarabut, RN). [The wreck of the submarine was found in 1995].

0638C/20 - Sighted two objects bearing 095°. Visibility was very poor.

0645C/20 - Identified the target as a large submarine of the Italian Marcello-class. Enemy's course was 300°, range 4800 yards. Commenced attack.

0649C/20 - The target altered course towards.

0654C/20 - Fired six torpedoes from 4600 yards. 3,5 Minutes after firing the first torpedo an explosion was heard but the result of the attack could not be observed as Trooper had gone deep as one of the torpedoes was a circle runner and kept the attacker down until the end of its run. Upon returning to periscope depth the submarine was no longer in sight. A small ship was sighted lowering a boat to pick up survivors. It is thought that the enemy submarine must have sunk. (6)

2 Aug 1943
At 0745C/2, HMS Trooper (Lt. G.S.C. Clarabut, RN) ended her 6th war patrol at Beirut. (6)

20 Aug 1943
Around 1945C/20, HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) departed from Beirut for her 7th war patrol. She was ordered to patrol in the Aegean. (6)

22 Aug 1943
At 2359C/22, HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) received Capt. S.1's signal timed 1914C/22, ordering her to patrol on the Piraeus - Rhodes route. (6)

25 Aug 1943
At 2330C/25, HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) received Capt. S.1's signal timed 2117C/25, ordering her to proceed with despatch to patrol off the Doro Channel. (6)

26 Aug 1943
At 0715C/26, when to the south of Icaria Island, HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) sighted a destroyer 8 miles to the east of her position.

Five minutes later masts of a trawler and the upperworks and masts of a 4000-5000 tons transport were seen. Range was 8 miles and the submarine was abaft the beam of the convoy so an attack was not possible. The enemy had come south through Icaria passage and was proceeding southwards most likely towards Rhodes.

By 0745C/26, the convoy was out of sight. HMS Trooper continued her passage towards the Doro Channel.

The ships sighted were most likely part of a convoy en-route from Piraeus to Leros which was made up of the transports Ardena (German, 1092 GRT, built 1915), Eolo (Italian, 704 GRT, built 1936) and Sinfra (German (former French), 4470 GRT, built 1929). They were escorted by the Italian destroyers Francesco Crispi, Turbine, Italian torpedo boat Castelfidardo and the German auxiliary submarine chaser UJ-2104. They had sailed from Piraeus at 1430/25 and arrived at Leros at 0944/26. (6)

28 Aug 1943
At 1150C/28, while off the Doro Channel, HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) sighted two torpedo boats of the Curtatone-class proceeding to the north-east at a speed of 15 knots. They passed at a distance of 5 nautical miles. These must have been the Calatafimi and Solferino coming from Piraeus and en-route to join the convoy made up of the tanker Celeno (Italian, 3741 GRT, built 1899) and the German auxiliary submarine chasers UJ 2109 and UJ 2102 coming from the Dardanelles.

[Identifiction of the torpedo boats from German documents as the Italian documents are missing for these two vessels during this period.] (12)

29 Aug 1943
At 0925C/29, while off the Doro Channel, HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) sighed what was thought to be a water carrier of about 600 tons escorted by two small armed motor boats coming north through the Doro Channel. They kept close to the north-west coast and proceeded nothwards for about 10 miles and then turned back. It was thought this might have been a 'submarine trap' and they were not attacked. (6)

30 Aug 1943
At 2105C/30, HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) surfaced after a days submerged patrol off the Doro Channel. She then set course to patrol off Samos. (6)

31 Aug 1943
At 1746C/31, HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) bombards a large tannery off Karlovassi, Greece. A total of 17 rounds were fired for 14 hits from a range of about 3000 from the shore. After 4 minutes she was forced to dive as she was taken under fire by a shore battery. It had been intended to also bombard a number of caiques that were being refitted near the breakwater but this did not materialise due to the return fire from the shore.

At 2300C/31, HMS Trooper received Capt. S.1's signal timed 1753C/31 advising a visit to the Gulf of Thessalonica. As this was 180 nautical miles away it was not possible to arrive there until late afternoon after a surface passage. Lt. Wraith therefore decided to patrol west of Skyros and then proceed to the Gulf of Thessalonica the next night. (6)

3 Sep 1943
At 2222C/3, HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) received Capt. S.1's signal timed 1016C/3, ordering her to return to Beirut. Course was set accordingly. (6)

4 Sep 1943
At 1400C/4, HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) received Capt. S.1's signal timed 1104C/4, ordering her to return to her previous patrol area to the north of Skiathos. Course was set accordingly. (6)

5 Sep 1943
HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) sank the Greek caique Maria M. (250 GRT) and Greek tug Nikolaos M. / Pi 2117 (35 GRT) with gunfire 2 nautical miles North of Skiathos, Greece.

1816C/5- Surfaced and engaged a large caique that was being towed by a tug that had come north through the Skopelos Channel. 52 Rounds were fired. The caique was sunk and the tug was abandoned and set on fire (it later sank). Two survivors from the tug were picked up. These two survivors provided valuable information on the harbour at Piraeus where they had spent almost the entire war on board the tug. (6)

10 Sep 1943
Around 0830C/10, HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) ended her 7th war patrol at Beirut. (6)

26 Sep 1943
HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN) departed from Beirut for her 8th war patrol. She is to carry out a special mission for SOE (Special Operations Executive) and then patrol in the Aegean Sea off the Dodecanese islands, including the Leros area.

30 Sep 1943
At 2130 hours, HMS Trooper (Lt. J.S. Wraith, DSO, DSC, RN), lands Colonel Diamantopoulos of the Royal Hellenic Artillery (code name 'Toby') of SOE (Operation ERUPTIION) with 2nd Lt. Vey and wireless operator 'Thomas' of ISLD (Operation CANTON) with 400 kgs of stores in Kalamos Bay (Euboa).

14 Oct 1943
At dawn, HMS Trooper, is sighted in Alinda Bay (Leros) by the schooner LS 8 (T/A/Lt.Cdr. A.C.C. Seligman, RNR) of the Levant Flotilla and they exchange signals. The Germans had laid several minefields about 10 miles east of Alinda Bay and it is quite possible that she was mined there not long afterwards.
