0917A/13, sighted the origin of the light about 1500 yards away on the starboard quarter. It was indeed seen to be a fishing vessel. HMS P 312 turned stern on. The fishing vessel then started to make Asdic transmissions so it turned out to be an enemy patrol vessel.

HMS P 312 kept stern on but then another, similar type vessel was sighted about 2500 yards away. One of them then appeared to be in contact for about three minutes but fortunately contact was then lost and they drew astern. Their A/S transmissions were heard on and off for the remainder of the day.

30 May 1943
While en-route from Algiers to her patrol area in the Gulf of Lyon HMS Trespasser (Lt. R.M. Favell, RN) fires three torpedoes (in error) at a dead whale. Position was about 30 nautical miles South of Mallorca, Spain.

0438B/30 - Sighted a dark shape on the port bow. The Officer of the Watch went to Night Alarm Stations. The dark shape turned out to be a large dead whale floating on the surface. As Trespasser passed it the first time it was thought to be a boat so Trespasser turned around to have another look. Lt. Favell was about to give the order 'Fall out Night Alarm Stations' when he realized that the torpedo tubes had not been reported as ready. He therefore gave the order 'Report when the tubes are ready'. He then turned his glasses once more at the whale. About 15 seconds later he saw the tracks of two torpedoes leave their tubes (three were fired). The order given was not understood correctly by the TGM (Torpedo Gunner's Mate) and thought to be 'Fire the Port tubes when ready'. The torpedo officer, who could otherwise has stopped this from happening was not in the forward torpedo room as he was at that moment the Officer of the Watch. (4)

5 Jun 1943
At 1150B/5, when in approximate position 43°00'N, 06°01'E, HMS Trespasser (Lt. R.M. Favell, RN) sighted what is thought to be an E-boat (motor torpedo boat) proceeding from the Gulf of Giens to a position two nautical miles south of Cape Cepet and then back.

At 1215B/5, another 'E-boat' was seen proceeding from Toulon harbour to the Gulf of Giens.

[We have been unable to identify these vessels.] (4)

6 Jun 1943
At 0727B/6, when in approximate position 42°59'N, 06°02'E, HMS Trespasser (Lt. R.M. Favell, RN) sighted what is thought to be a (former) French La Cordeliere-class torpedo boat entering Toulon harbour coming from the eastwards. Range was 9000 yards and as these ships only draw 8 feet. Lt. Favell did not attempt to start an attack.

This must have been the German torpedo boat TA 10 (former French La Pomone) on passage from Genoa to Toulon. (15)

7 Jun 1943
At 0730B/7, when in approximate position 43°02'N, 06°02'E, HMS Trespasser (Lt. R.M. Favell, RN) sighted nine motor minesweepers (R-boats) and / or motor torpedo boats (E-boats) as well as a brigantine sweeping the channel from Little Pass in a direction of 302° to the entrance to Toulon Bay, then to position 092° - Cape Cepet - 2 miles and from there in a direction of 180° Freres Isles - 1 nautical mile. They were lost from sight around 0930B/7 when fog descended on the area. The fog lifted at 1045B/7.

At 1515B/7, a large trawler was seen to the south of Cape Sicie. She was later seen to enter Toulon harbour.

[We have been unable to identify these vessels.] (4)

8 Jun 1943
HMS Trespasser (Lt. R.M. Favell, RN) fires six torpedoes at a tanker off Marseilles, France. No hits were obtained.

Looking at German sources the convoy must have been the following; three tanker barges Savoie, Norte and Citerna XI. They were escorted by UJ 2214, R 1, R 6, R 7 and R 8. They had sailed from Marseille at 0700 hours and arrived at Toulon at 1355 hours. They did not observe the attack (which was a long range attack, carried out from 6000 yards) but the description of the convoy fairly matches the one given by Trespasser: three tankers escorted by an A/S trawler and several E-boats and if one looks at a map they should have been in the vicinity of HMS Trespasser at that time.

0910B/8 - In position 160° - Cassidaigne Reef - 3.5 nautical miles sighted a large A/S trawler off Riou Island (near Marseilles, France). It appeared to be patrolling up and down. As this was the last day of the patrol Lt. Favell decided to take a shot at it.

1000B/8 - Sighted three tankers and another trawler coming out of the mist. Shifted target to this convoy. Decided to attack the stern most tanker. About six smaller A/S vessels were also observed to be around this convoy.

1014B/8 - Fired 6 torpedoes at the third tanker (thought to be about 4000 tons) and then went deep. Range was 6000 yards.

1018B/8 - Heard one explosion that sounded like a torpedo hitting the target, giving it a running range of nearly 5850 yards.

1021B/8 - Heard five more explosions as the rest of the torpedoes hit the shore. An ineffective counter attack followed by the two A/S trawlers and a couple of smaller A/S vessels. No depth charges were dropped.

1600B/8 - After reloading the torpedo tubes returned to periscope depth to find nothing in sight. Then left patrol as ordered by Capt. S 8 in his signal timed 1616B/6. (16)

12 Jun 1943
Around 0900B/12, HMS Trespasser (Lt. R.M. Favell, RN) ended her 4th war patrol (2nd in the Mediterranean) at Algiers. She was escorted in and had met the escort around 0630B/12. [Identity of the escort not known.] (4)

14 Jun 1943
In the morning, around 0800B/14, HMS Trespasser (Lt. R.M. Favell, RN) departed Algiers for Oran. (17)

15 Jun 1943
Around 1000B/15, HMS Trespasser (Lt. R.M. Favell, RN) arrived at Oran from Algiers. (17)

16 Jun 1943
HMS Trespasser (Lt. R.M. Favell, RN) is docked in the floating dock at Oran. (17)

18 Jun 1943
HMS Trespasser (Lt. R.M. Favell, RN) is undocked. She then left Oran around 0900B/18 for Algiers shortly afterwards. (17)

19 Jun 1943
Around 0800B/10, HMS Trespasser (Lt. R.M. Favell, RN) arrived at Algiers. (17)

28 Jun 1943
Around 2000B/28, HMS Trespasser (Lt. R.M. Favell, RN) departed from Algiers for her 5th war patrol (3rd in the Mediterranean). She is to patrol in the Tyrrhenian Sea, to the west of Giglio Island, to give cover for the Allied landings on Sicily.

For the daily positions of HMS Trespasser during this patrol see the map below.

4 Jul 1943
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) made a torpedo attack on a convoy of two merchant vessels of about 3000 tons, thought to be possibly armed merchant cruisers. No hits were obtained.

These ships were in fact the German auxiliary minelayers Brandenburg and Pommern escorted by auxiliary patrol vessel SG 13 on passage from La Maddalena to Livorno where they were to pick up troop. It was the Brandenburg which reported being that she was missed by a torpedo.

1250B/4 - In position 42°22'N, 10°38'E sighted two ships bearing 206° coming straight towards. The ships were in line abreast and about 1000 yards apart. Turned towards and started attack. Enemy course was 026°

1308B/4 - Fired two torpedoes from 1700 yards. The speed of the targets was estimated at 18 knots. Both torpedoes missed due to a failed setup of the attack. (4)

7 Jul 1943
At 0930B/7, to the west of Giglio Island, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) sighted a small armed trawler passing through the area on a course of 085°. She was not attacked.

[We have been unable to identify this vessel.] (4)

10 Jul 1943
At 2325B/10, to the south-west of Giglio Island, in approximate position 42°14'N, 10°42'E, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) sighted two darkened ships bearing 330°. They were steering 220°. HMS Trespasser commenced to close at speed and the bow torpedo tubes were brought to the ready. The speed of the enemy was estimated at 8 knots. One was at first thought to be a large submarine but when the enemy ships crossed the moons path they were though to be patrol vessels. It also became apparent that HMS Trespasser was much closer than thought.

[We have been unable to identify these vessels.] (4)

11 Jul 1943
At 1310B/11, to the west-north-west of Giglio Island, in approximate position 42°26'N, 10°38'E, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) sighted two ships bearing 160°. When first sighted they looked like small destroyers but later were seen to be large ML-type vessels. When looked at from forward of 30 degrees on the bow they looked like large U-boats. They were patrolling to the west of Giglio on a 250° - 070° course and dropping small depth charges or acoustic charges at intervals. They were not pinging.

It was now thought this must also have been the same vessels that had been seen last night.

Around 1500B/11, the patrol vessels were seen leaving the area westwards. [We have been unable to identify these vessels.]

At 1535B/11, smoke was seen to the southwards. This developed into a large merchant vessel escorted by an auxiliary A/S trawler, possibly an UJ boat. The merchant vessel was very light, half of her propeller was out of the water. Enemy speed was 8 knots. An attack was stated but in the final phase of the attack HMS Trespasser was put down by the escort and hunted for 1.5 hours. No depth charges were dropped though despite the fact that the escort passed overhead three times.

At 1800B/11, HMS Trespasser returned to periscope depth. The merchant vessel was seen 8000 yards to the northward running in circles so that the escort could catch up.

The ships sighted at 1535B/11, were most likely the transport Nino Padre (4171 GRT, built 1913) and her escort, the German auxiliary submarine chaser UJ 2207 on passage from Naples (departed 1550B/10) to La Spezia (arrived 1850B/12) but UJ 2207 was detached to Porto Ferraio earlier. Their speed of advance was 6.5 knots (source Maricotraf, Vol. 15). However, if you plot this on a map, both vessels would have been quite a bit south of Giglio Island, but perhaps there is an error somewhere. (18)

13 Jul 1943
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) sank the Italian auxiliary patrol vessel V8 / Filippo (242 GRT) with gunfire about 25 nautical miles south of Bastia, Corsica, France.

0900B/13 - In position 42°19'N, 09°56'E, sighted funnel tops bearing 280°. Ran in at speed for 15 minutes but the range could not be closed then 12000 yards. A large trawler could be identified but of the other ship only the funnel top was all that could be seen. The enemy ships were southbound. [We have been unable to identify these vessels.]

1135B/13 - In position 42°20'N, 09°50'E, sighted a large three masted schooner of about 200 tons in position 42°20'N, 09°50'E. She was laying stopped with her stern to a sea anchor or some sort of buoy.

1230B/13 - Surfaced and opened fire on the schooner with the deck gun. The crew of the schooner abandoned ship and the vessel burst into flames.

1447B/13 - Sighted two patrol vessels of the same type that had seen before on this patrol carrying out an A/S sweep in the area. They never gained contact but were a nuisance until the disappeared to the south-west around 2115B/13. This were most likely the Italian corvettes Cormorano and Danaide which were on an A/S sweep. (4)

14 Jul 1943
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) makes a torpedo attack on an unescorted 6000-ton merchant vessel in approximate position 42°46'N, 09°49'E and misses. One torpedo has a gyro failure and circles near the submarine.

The transport Sassari (Italian (former French Sidi Mabrouk), 2485 GRT, built 1917) had departed Bastia around 0600B/14 for Leghorn where she arrived around 1530B/14. At the same time the Italian naval auxiliary Silvia Onorato (208 GRT, built 1895) had also departed Bastia for Portoferraio (Elba) where she arrived around 1045B/14. From the description of the target given by Lt.Cdr. Favell it was, most likely, the Sassari that was the target.

0800B/14 - In position 42°46'N, 09°49'E sighted a large unescorted merchant vessel bearing 180° at a range of about 11000 yards. Enemy course was 081° at a speed of 9 knots. Ran in at speed.

0830B/14 - Fired four torpedoes from 8100 yards(!) at this merchant vessel which was estimated as being of around 6000 tons. No hits were obtained. One torpedo has a gyro failure and circles near the submarine.

0900B/14 - Sighted a large tanker to the northwards. She had apparently just left Bastia and was steering a course of around 050° and was passing to the south of Capraia Island. This must have been the tanker Champagne (German (former French), 9946 GRT, built 1938) escorted by the German auxiliary patrol vessel SG 10 as they had sailed from Bastia at 0700B/14 for Leghorn.

1015B/14 - Sighted a landing ship (barge) passing 6000 yards to the southwards on a course of 070° at a speed of 10 knots. This may have been the self-propelled German fuel barge Star en-route from Bastia (departed around 0600B/14) to Leghorn.

1130B/14 - Received Capt. S 8's signal timed 0834B/14 which stated that two battleships, a cruiser and a destroyer had been sighted in position 43°54'N, 09°40'E proceeding on a course of 190° at 15 knots. It was decided to keep a full bow salvo of eight torpedoes ready to attack these ships if they may show up.

1330B/14 - A destroyer was sighted passing through the area, looking like one of the Tigre class. Her course was 165°. It was thought this ship may be patrolling ahead of what was to come.

This was most likely the destroyer FR 22 (former French Panthère) who sailed at 0830B/14 from La Spezia for Naples where she arrived at 08745B/15.

1345B/14 - Received Capt. S 8's signal timed 0934B/14 which stated that the previous enemy report had been a false one.

1415B/14 - Sighted three most peculiar ships, whose silhouette was just like a large submarine, to the southward at a range of 8000 yards. Their course was 250°. They were thought to be either patrol craft or landing ships. The range was too great to identify them properly.

[We have been unable to identify these vessels.]

1745B/14 - Sighted the masts and upperworks of two patrol vessels who were carrying out an A/S sweep bearing 210°. Most likely this were the same vessels that had been seen yesterday afternoon. This were most likely the Italian corvettes Cormorano and Danaide who were on A/S sweep. (19)

15 Jul 1943
At 0040B/15, in position 42°30'N, 09°50'E, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) sighted a patrol vessel laying stopped or moving very slowly to the northward. HMS Trespasser turned away to avoid the enemy vessel. [We have been unable to identify this vessel.]

At 1130B/15, in position 42°15'N, 09°58'E, HMS Trespasser sighted the masts and funnel tops of a Leone-class destroyer. HMS Trespasser turned towards and increased speed to close but the destroyer soon disappeared to the southward.

This was possibly the light cruiser Scipione Africano which had sailed from La Spezia at 0616B/15 and was bound for Taranto. (4)

17 Jul 1943
At 2228B/17, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) surfaced after a day of submerged patrol. She then set course to leave patrol and return to Algiers as ordered in Capt. S 8's signal timed 1456B/15. (4)

23 Jul 1943
Around 0730B/23, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) ended her 5th war patrol (3rd in the Mediterranean) at Algiers. She had met the escort (identity not known) around 0620B/23. (4)

For the daily positions of HMS Trespasser during this patrol see the map below.

(4)

3 Sep 1943
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) attacked an enemy convoy with four torpedoes south of Kos in position 36°37'N, 27°21'E. No hits were obtained.

The convoy attacked was the one made up of the transports Silva (Italian, 646 GRT, built 1889), Pola (Italian, 451 GRT, built 1941) and Postiglioni (Italian, 194 GRT, built 1928). They were escorted by the Italian destroyer Turbine and the German auxiliary submarine chaser UJ 2110. They had departed from Leros at 1500B/3 and arrived at Rhodes at 0645B/4. Speed had been 7.5 knots.

2330C/3 - Sighted a convoy of two small merchant ship escorted by a destroyer and three Italian RD-class minesweepers to the north. Distance was 6000 yards. Turned towards and started attack.

2352 hours - Fired four torpedoes from 3200 yards at one of the merchant vessels and went deep to 300 feet. The torpedoes most likely missed ahead as the speed was overestimated. No counter attack followed. (21)

4 Sep 1943
At 0130C/4, in approximate position 36°37'N, 27°21'E, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) sighed an enemy patrol vessel laying stopped bearing 090°. HMS Trespasser turned away and evaded to continue her battery charge between Niseros and Piskopi.

At 0320C/4, with the battery charge completed and now proceeding eastward to the patrol area, HMS Trespasser sighted three very small ships proceeding northwards at very slow speed. One of them looked like a trawler, one a cross between a trawler and a tanker and one looked like an E-boat (motor torpedo boat). They were most likely some sort of patrol. [We have been unable to identify these vessels.]

Lt.Cdr. Favell decided to proceed westwards and to patrol to the south of Kandelioussa during the day. (4)

5 Sep 1943
At 0027C/5, in approximate position 36°31'N, 27°19'E, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) sighted darkened ship which turned out to be a small patrol craft, possibly an Italian RD-class minesweeper. It was also much closer then it was initially thought to be so at 0034C/5, HMS Trespasser dived to 200 feet. The enemy kept starting and then stopping to listen. Also Asdic was used but she never gained contact despite the enemy passing overhead at 0115C/5.

At 0230C/5, HMS Trespasser surfaced to find nothing in sight.

At 0442C/5, a patrol craft was seen laying stopped about 6 nautical miles to the south-west of Seskli Island. HMS Trespasser turned away to evade this patrol craft.

During the day only some small caiques were seen proceeding through the area.

At 2330C/5, in approximate position 36°28'N, 27°38'E, a small low vessel was sighted midway between Piskopi and Symi proceeding on a course of 300° at 6 knots. She appeared to be the Italian RD-class minesweeper seen earlier today. HMS Trespasser turned away to avoid the enemy vessel.

[We have been unable to identify the vessels sighted on this day.] (4)

6 Sep 1943
At 1015C/6, north of Rhodos, in approximate position 36°30'N, 28°06'E, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) two motor caiques of about 50 to 100 tons were sighted passing to the south at a range of 2000 yards. They were in line abreast about three cables apart making good about 5 knots. They eventually to the westwards south of Symi.

At 1400C/6, the same two caiques were now seen two miles to the southward. They were proceeding slowly westwards in line ahead. They were later seen to turn to return to Rhodos in company. Lt.Cdr. Favell suspected these caiques had been minesweeping. Both were flying the Italian flag and did not seem to be armed although any armament could have been concealed. (4)

7 Sep 1943
At 0120C/7, in approximate position 36°28'N, 27°40'E, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) sighted a darkened vessel. At first this ship appeared much larger then the usual patrols that had been encountered lately. She was closed on the motors until it became clear that the enemy was laying stopped. It was thought it may have been a 'Generali-class' torpedo boat. [None was in the area so this is thus not possible.] HMS Trespasser then turned away to avoid.

At 0450C/7, a small boat was seen, possibly an ML-type or perhaps and E- or R-boat. HMS Trespasser dived to avoid. No HE was picked up. During the day HMS Trespasser patrolled between Piskopi and Symi.

At 1820C/7, three sailing caiques of about 20 tons each proceeding towards Cape Krio. They were not attacked to not give HMS Trespasser's position away.

[We have been unable to identify the vessels sighted on this day.] (4)

8 Sep 1943
At 0150C/8, in approximate position 36°27'N, 27°42'E, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) sighed a small vessel which was obviously patrolling. She appeared to be an Italian RD-class minesweeper. The enemy was not using Asdic but was heard to fire acoustic charges occasionally. At 0220C/8, HMS Trespasser turned away to avoid. [We have been unable to identify this vessel.]

At 0511C/8, HMS Trespasser dived and patrolled off Cape Krio during the day.

During the day two Turkish ships and two Swiss Red Cross ships were seen. It was clear that the enemy only moved to Rhodos during darkness.

At 2100C/8, information was received from the BBC news that an armistice with Italy had been signed. (4)

9 Sep 1943
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) makes a torpedo attack on an enemy convoy. All torpedoes fired missed their intended target.

[No Italian records are available for this period. In German records we have been unable to find anything regarding this convoy.]

0006C/9 - Sighted two small ships in position 090° - Piskopi Head - 8 nautical miles (approx position was 36°27'N, 27°39'E). These turned out to be a small coaster of about 500 tons escorted by an armed trawler.

At 0114C/9 - Capt. S 1's signal timed 2339C/8 was received which was an emergency signal that unfortunately was incorrectly cyphered. After an hour of hard work it was discovered where the fault lay and the signal could be read. It contained instructions how to deal with the now changed situation given the Italian armistice.

0307C/9 - After shadowing the ships for three hours it was obvious these were not proceeding to Alexandria to surrender so attacked with three torpedoes from 600 yards. No hits were obtained. One torpedo was seen to pass under the target. No counter attack followed.

HMS Trespasser patrolled between Piskopi and Symi during the day but nothing at all was sighted. (4)

10 Sep 1943
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) attacked the Italian destroyer Euro with five torpedoes. No hits were obtained.

Euro was proceeding from Leros to Rhodes at the time of the attack.

0905C/10 - In position 7 nautical miles south-east of Cape Alupo sighted a destroyer wearing the Italian ensign. She did not fly a blue pendant meaning she was surrendering so therefore she was attacked. Five torpedoes were fired but no hits were obtained. The torpedoes are thought to have missed astern.

The destroyer was then seen to be approaching Rhodos harbour. She hoisted a recognition signal consisting of four black balls and was then immediately fired upon by shore batteries whose fire she returned. The destroyer then turned back on the same route that she had taken on the way in. She disappeared to the south-west.

1425C/10 - A motor torpedo boat, heavily laden with passengers was seen leaving Rhodes and proceeding round Cape Alupo northwards towards the Gulf of Symi. (4)

11 Sep 1943
At 1700C/11, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) saw one motor torpedo boat and a fast motorboat leaving Rhodes harbour while being fired upon by shore batteries. They proceeded towards the Gulf of Symi. (4)

12 Sep 1943
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) attacks a merchant ship with two torpedoes. No hits were obtained.

Perhaps this was the German transport Taganrog (508 GRT, built 1899) now under Italian control and escaping from Rhodos to Leros.

0725C/12 - When in position 090° - Kos roads - 4 nautical miles sighted a 1000 tons merchant vessel approaching from Cape Krio. Attacked with two torpedoes from 3300 yards, both of which missed. As the ship was in ballast the torpedoes most likely ran under. (4)

14 Sep 1943
At 0015C/14, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) received Capt. S 1's signal timed 1029C/13 recalling her from patrol. Also Capt. S 1's signal timed 1554C/13 was received which stated that the entire Aegean was now controlled by the Germans. Lt.Cdr. Favell therefore decided to remain on patrol another day and have a shot at the depot ship that had been seen inside Kos harbour on the 12th. Course was thus set for Kos.

At 0430C/14, Capt. S 1's signal timed 0045C/14 was received which stated that Kos was in Allied hands. Course was thus set to leave patrol via the Scarpanto Straits. (4)

16 Sep 1943
Around 1000C/16, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) ended her 6th war patrol (4th in the Mediterranean) at Beirut. (4)

10 Nov 1943
Around 0930FG/10, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) departed from Colombo for her 7th war patrol (1st in the Far East). She is to patrol in the Malacca Straits and off the Nicobar Islands.

On departure D/F calibration trials and gunnery exercises as well as A/S exercises were carried out with HMS Shoreham (Cdr. E. Hewitt, RD, RNR), HMAS Bathurst (T/Lt. C. Macdonald, RANR(S) and HMIS Rajputana (Lt. W.G. Coltham, RIN). Also a practice attack was made on HMS Shoreham.

On completion of the exercises around 1825FG/10, HMS Trespasser proceeded on patrol. (4)

10 Nov 1943
For the daily positions of HMS Trespasser during her 7th war patrol see the map below.

22 Nov 1943
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) attacked a northbound Japanese convoy of four transports escorted by two submarine chasers south-east of Diamond Point, Sumatra, in position 04°45'N, 98°04'E. Three stern torpedoes were fired but no hits were obtained.

The exact composition of the convoy is not known but the Japanese transport Unkai Maru No. 12 reported being missed by two torpedoes in approximately this position on this day.

0758FG/22 - Sighted smoke bearing 147°. Started attack. The convoy turned out to be made up of 4 transports of about 4000 tons escorted by two submarine chasers.

0915FG/22 - Fired three stern torpedoes against one of the merchant ships. No hits were obtained, most likely the torpedo tracks were spotted.

Both submarine chasers hunted the submarine for two hours but did not gain contact. (4)

24 Nov 1943
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) gets caught in fishing stacks off Penang Island but no obvious damage to the submarine is done. After returning from patrol she is docked to check for damage.

0600FG/24 - Sighted a vessel bearing 210° approaching the submarines position. This turned out to be an auxiliary patrol vessel not unlike a trawler. She was not using Asdic. She then proceeded northwards up the west coast of Penang Island.

Around 1600FG/24, HMS Trespasser a fishing stack got caught on something aft and then 'took station' about 10 yards astern of the periscope. Going deep and increasing speed could not shake it off.

1730FG/24 - The same patrol vessel that had been seen in the morning was seen approaching from the northward coming southwards along the coast. She eventually passed 1000 yards to seaward. (4)

27 Nov 1943
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) sighted the Japanese seaplane carrier Kamoi (offsite link) off Car Nicobar Island. Lt.Cdr. Favell is unable to attack as the range could not be sufficiently closed.

1355FG/27, sighted smoke bearing 130°. Altered course towards to close. This contact turned out to be the Japanese seaplane carrier Kamoi. Range could not be closed to less then 7 miles as the enemy ship turned away. She was seen to enter Sawai Bay where it must have anchored. (4)

28 Nov 1943
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) makes a torpedo attack on an escorted Japanese transport to the South-East of Car Nicobar Island in position 08°47'N, 93°10'E. All torpedoes missed their intended target.

The target was the Unkai Maru No. 12 on passage from Sabang to Car Nicobar.

1048FG/28 - Sighted smoke bearing 285°. Ran at speed to the south until masts and a funnel of a merchant ship escorted by a trawler were sighted. The merchant ship was similar to the Peking Maru.

1423FG/28 - Commenced attack.

1504FG/28 - In position 08°47'N, 93°10'E fired six torpedoes from an estimated range of 4600 yards, went deep. Three explosions were heard the first 4 min. 50 sec. after firing. The HE of the target ceased. The trawler hunted Trespasser for over an hour but no depth charges were dropped. It was thought possible that the target was sunk. (4)

29 Nov 1943
At 1900FG/19, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) left patrol to proceed to Trincomalee as ordered in Capt. S 4's signal timed 1819Z/28. (4)

3 Dec 1943
Around 1900FG/3, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) ended her 7th war patrol (1st in the Far East) at Trincomalee. (4)

8 Dec 1943
Around 0715FG/8, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) departed from Trincomalee for Colombo to dock. This is to see if damage is done when Trespasser got stuck in fishing stacks on November 24th.

She was escorted by the Italian sloop Eritrea. (26)

9 Dec 1943
Around 1930FG/9, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) arrived at Colombo. (26)

14 Dec 1943
Around 0800FG/14, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) departed from Colombo to return to Trincomalee.

But first A/S exercises were carried out with HMAS Lismore (T/Lt. L.C.G. Lever, RANR(S)). These were completed around 1310FG/14.

Around 1415FG/14, HMS Trespasser was joined by the Italian sloop Eritrea and course was set for Trincomalee. (26)

16 Dec 1943
Around 1130FG/16, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) arrived at Trincomalee from Colombo. (26)

26 Dec 1943
Around 1600FG/26, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) departed from Trincomalee for her 8th war patrol (2nd in the Far East). She is to patrol of the West coast of Burma and to perform special mission 'Breech'.

She was escorted out until around 2130FG/26 by HMS Lord Grey (T/Lt. J.J. Challis, RNVR). (4)

26 Dec 1943
For the daily positions of HMS Trespasser during hr 8th war patrol see the map below.

31 Dec 1943
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) landed an agent on Tavoy Island (13°11'N, 98°15'E) as part of operation Breech, part 1.

0440FG/31 - Dived in position 8 miles bearing 277° from the northernmost part of Tavoy Island and proceeded inshore to carry out a periscope reconnaissance.

During the reconnaissance it was decided to land the agent in a bay in position 13°11'20"N, 98°14'50"E. This bay appeared deserted and had a small sandy beach.

1850FG/31 - Surfaced and retired to seaward while charging.

2210FG/31 - The moon set. Proceeded inshore.

2230FG/31 - Disembarked the agent about 3/4 of a mile from the selected position and waited for his signal that he had successfully landed.

2355FG/31 - Just as Trespasser was about to leave having received no signal the agents signal was seen. Trespasser then retired to seaward and set course for the North Moscos Islands. (27)

1 Jan 1944
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) dropped off two agents near Reef Island (North Cosmos Islands) as part of operation Breech, part 2.

0529FG/1 - Dived in position 7 miles bearing 270° from South Island, Middle Cosmos Islands and continued to proceed northwards while submerged.

1400FG/1 - Passed to the south of Long Island, North Cosmos Islands and now set course for position 2.75 miles bearing 090° from Reef Island. Several large junks and some fishing sampans were sighted in the area.

1900FG/1 - Surfaced and charged the batteries to the south of Long Island.

2205FG/1 - The moon set. Proceeded to a position 5 miles bearing 056° from Reef Island.

2220FG/1 - Disembarked two agents in a Folbot. At this time two junks were in sight about two miles off. When the Folbot became waterborne also a small fishing sampan appeared about 300 yards away. The tree occupants were taken on board and the two agents transferred their gear to the Sampan also taking the Folbot with them and if they were not going to need it they would sink it.

During interrogation it became evident that the fishermen had not seen the submarine. HMS Trespasser now set course to clear the area. (27)

4 Jan 1944
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) attempted to pick up the agent who was landed on Tavoy Island on 31 December 1943 but he fails to make the rendezvous.

0522FG/3 - Dived 5 nautical miles to the west of Tavoy Island. Then continued to proceed inshore to conduct a periscope reconnaissance of the pick up area on completion of which HMS Trespasser patrolled five miles from the shore.

0110FG/4 - The moon set.

0130FG/4 - Reached the rendezvous position.

0140FG/4 - Flashing was seen but not from the correct place but about a mile away from where the agent was landed. The flashing appeared to be from a torch pointed at the submarine but it was not in accordance with the pre-arranged signal.

0200FG/4 - The torch flashed at the submarine again, this time much more brightly. No more flashing was seen after this time.

0400FG/4 - With the agent not having appeared the area was searched to the seaward in case he had missed the submarine and had returned to the bay.

0430FG/4 - The operation was abondoned as there was no sign of the agent. Course was then set to patrol off Port Blair. (4)

5 Jan 1944
At 1040FG/5, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) passed a trawler proceeding to the eastwards at speed. An aircraft accompanied this trawler.

At 1150FG/5, two more aircraft were sighted and it was thought, HMS Trespasser may have been sighted earlier in the day.

At 1310FG/5, the trawler and aircraft re-appeared and the trawler came to within half a mile so Trespasser turned away to evade. The trawler was then seen proceeding towards Port Blair at slow speed.

At 1500FG/5, when in position 11°37'N, 92°53'E a large ship was sighted close under the land steering north. It was most unfortunate that she had not been sighted earlier as she was now out of range and could not be attacked.

She was very difficult to see against the high mountains and into the sun. She passed up the coast but instead of entering the harbour she turned round and came back south again. The ship was now identified as a seaplane tender.

By now there were five trawlers near the harbour entrance and it was now tought that there may be a problem with the boom at Port Blair and that no ships could enter the harbour.

Trespasser meanwhile proceeded southwards along the coast about 6000 yards from shore in the hope the seaplane tender might return but unfortunately this was not the case.

The seaplane tender sighted must have been the Kiyokawa Maru.

At 1915FG/5, as it was getting dark, two trawlers were seen fairly close.

At 1930FG/5, a trawler got rather close at a range of only 1500 yards.

At 2015FG/5, HMS Trespasser surfaced and proceeded to seawards to charge. (4)

6 Jan 1944
At 0310FG/6, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) sighted a trawler crossing the stern at a range of 3000 yards. HMS Trespasser turned stern on and was about to turn of the diesels and start up the motors when the trawler suddenly turned towards and increased speed obviously having detected the submarine so HMS Trespasser dived.

Six depth charges were dropped and later two more vessels were heard to join the hunt.

At 0615FG/6, HMS Trespasser returned to periscope depth to find nothing in sight.

At 0800FG/6, the masts of a patrol vessel were seen bearing 270°. It disappeared an hour later.

At 1300FG/6, the masts re-appeared. It was now thought to be a fleet minesweeper. At 1515FG/6 the enemy vessel again disappeared from sight.

[Perhaps the ship sighted was the torpedo boat Kari which may have been in the area.] (4)

11 Jan 1944
Around 1900FG/11, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) left patrol to return to Trincomalee. (4)

15 Jan 1944
Around 0900FG/15, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) ended her 8th war patrol (2nd in the Far East) at Trincomalee. (4)

26 Jan 1944
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) is fumigated at Trincomalee. (28)

31 Jan 1944
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) departed from Trincomalee for her 9th war patrol (3rd in the Far East). She is to perform a special operation ('Operation Corton') and to patrol of the west coast of Burma and off the Nicobar Islands.

On departure gunnery exercises were carried out as well as A/S exercises with HrMs Tromp (A/Capt. F. Stam, RNN). (4)

31 Jan 1944
For the daily positions of HMS Trespasser during her 9th war patrol see the map below.

5 Feb 1944
HMS Trespasser (Lt.Cdr. R.M. Favell) landed agents in three Folbots and three large rubber boats north of Sir John Metcalfe Island ('Operation Corton'). Arrangements are made for the agents to be picked up on 31 March or 1 April.

0530FG/4 - Dived in position 12°15'N, 97°37'E. Proceeded to carry out a periscope reconnaissance of Elphinstone Island.

A place was chosen for the landing which was a bay on the south-westernmost point of the island (12°18'45"N, 97°57'45"E).

1300FG/4 - Proceeded to seawards.

1905FG/4 - Surfaced and charged.

0200FG/5 - Stopped in position 5 miles north of Sir John Metcalfe Island. Got up three Folbots and three Z type large rubber boats on the casing.

0230FG/5 - Proceeded inshore.

0305FG/5 - The moon set.

0330FG/5 - Disembarked the landing party who proceeded inshore.

0505FG/5 - Received a flashing signal from the party that they were ashore and that all was well. HMS Trespasser then proceeded to seawards. (29)

18 Feb 1944
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) torpedoed and damaged the Japanese auxiliary gunboat Eifuku Maru (3520 GRT, built 1939) off Nancowry Island in position 07°52'N, 93°38'E.

1050FG/18 - While in position 121° - Cape Connaught - 4 nautical miles sighted three ships bearing 206°. Distance was about 8000 yards. These were one merchant ship escorted by a minesweeper and one other ship thought to be a trawler. Started an attack.

1109FG/18 - Fired six torpedoes from 3500 yards. 2 minutes and 20 seconds after firing an explosion was heard and the targets HE ceased. A muffled explosion followed a few seconds later. Trespasser went deep upon firing. The minesweeper dropped 19 depth charges over a period of about an hour. No damage was done by these depth charges.

1215FG/18 - Returned to periscope depth to find the minesweeper in sight hull down to the East of Cape Connaught. Nothing else was in sight. The target is thought to have sunk. (4)

19 Feb 1944
Between 0800FG/19 and 1300FG/19, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) carried out a reconnaissance of Sawai Bay, Car Nicobar Island.

At 1925FG/19, she left patrol to return to Trincomalee as ordered in Capt. S 4's signal timed 0746Z/14. (4)

22 Feb 1944
Around 1920FG/22, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) ended her 9th war patrol (3rd in the Far East) at Trincomalee.

She was escorted in by Eritrea which had joined around 1715FG/22. (4)

7 Mar 1944
Around 0900FG/7, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) departed from Trincomalee for her 10th war patrol (4th in the Far East). She is to lay a minefield, perform a special mission ('Operation Mullet') and to patrol in the Malacca Straits.

She was escorted out until around 1515FG/7 by HMS Lord Grey (T/Lt. J.J. Challis, RNVR). (4)

7 Mar 1944
For the daily positions of HMS Trespasser during her 10th patrol see the map below.

13 Mar 1944
At 0201FG/13, when 10 miles to the south of Pulau Perak, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) sighed an S-class submarine bearing 160° at a range of about 6000 yards. This was thought to be HMS Storm (T/Lt. E.P. Young, DSC, RNVR). HMS Trespasser passed a recognition signal by signal lamp and then dived.

The submarine in question was indeed HMS Storm which reported seeing a darkened vessel bearing 330° which looked very much like a submarine. HMS Storm turned stern on but then lost sight of the target. At 0214FG/13, the Officer of the Watch and one lookout sighted a red-flashing Aldis challenge on bearing Red 50°. HMS Storm turned hard-a-starboard and retired at speed. It was now thought this may be a patrol vessel and not a submarine. (30)

14 Mar 1944
HMS Trespasser (Lt.Cdr. R.M. Favell, RN) laid 12 mines in the Malacca Straits off the east coast of Sumatra. (This was Minelaying Order (M.L.O.) 2).

0525FG/14 - Dived in position 190° Pulo Berhala 17 nautical miles.

0741FG/14 - Commenced laying four mines 600 feet apart in a direction of 220° from position 03°28'20"N, 99°29'20"E.

0906FG/14 - Commenced laying four mines 600 feet apart in a direction of 220° from position 03°27'30"N, 99°29'40"E.

1000FG/14 - Commenced laying four mines 600 feet apart in a direction of 220° from position 03°26'20"N, 99°30'40"E.

1130FG/14 - Sighted a submarine chaser steering a course of 120° and it appeared she proceeded right through the first line of mines which were at that time still be set to safe.

1230FG/14 - The submarine chaser disappeared to the south-eastward. (4)

14 Mar 1944
At 0025FG/14, in position 04°10'N, 99°28'E, HMS Templar (Lt. D.J. Beckley, DSO, RN) sighted a vessel thought to be a destroyer or submarine. As it was considered possible that this was HMS Trespasser (Lt.Cdr. R.M. Favell, RN), HMS Templar dived and avoided. HE quickly faded.

[HMS Trespasser reported nothing around this time but it is indeed very well possible that she was the vessel sighted as she was indeed in this area.] (4)

15 Mar 1944
During the period of 15 to 18 March 1944, HMS Trespasser (Lt.Cdr. R.M. Favell, RN) carried out a special operation ('Operation Remarkable II').

During this period HMS Trespasser patrolled in a position about 4 to 8 nautical miles to the south of Pulau Jarak.

At 0515FG/15, a submarine chaser was sighted 6 miles to the south of Pulau Jarak. HMS Trespasser dived to avoid detection.

During the remainder of the 15th, which was not one of the rendezvous dates, a few small junks and sampans were seen.

During 16 and 17 March nothing at all was seen in the area.

On the 18th, Trespasser patrolled in position 151° - Pulau Rumbia - 11.5 nautical miles. Several junks and small fishing sampans were seen but none were displaying the recognition signal.
