Around 1000A/11, HMS P 314 (Lt.Cdr. A.F. Collett, DSC, RN) arrived at Lerwick. She departed Lerwick around 2030A/11 for her 1st war patrol. She was ordered to patrol off northern Norway to provide cover for convoy operations to and from northern Russia.

Twenty minutes after departing P 314 returned to Lerwick with a major defect to the starboard main motor. (4)

18 Jan 1943
After repairs to her starboard main motor, HMS P 314 (Lt.Cdr. A.F. Collett, DSC, RN) departed from Lerwick around 1400A/18, to resume her 1st war patrol.

For the daily positions of HMS P 314 during this patrol see the map below.

(4)

26 Jan 1943
At 2020A/26, HMS P 314 (Lt.Cdr. A.F. Collett, DSC, RN) received Capt. S 9's signal timed 1813A/26, ordering hr to leave patrol at midnight and return to Lerwick.

At 2359A/26, HMS P 314 left patrol to comply with the above orders. (4)

29 Jan 1943
At 1209A/29, HMS P 314 (Lt.Cdr. A.F. Collett, DSC, RN) received Capt. S 9's signal timed 1121A/29, which ordered her to patrol in a position to the north of Trondheim, Norway (64°35'N, 09°44'E).

Course was set to comply with these orders and HMS P 314 arrived in the ordered position at 0900A/30. (4)

31 Jan 1943
At 2205A/31, HMS P 314 (Lt.Cdr. A.F. Collett, DSC, RN) received Capt.

Course was set accordingly and HMS P 314 arrived in this new patrol position around noon the following day. (4)

5 Feb 1943
At 1000A/5, west of Kristiansund, Norway, HMS P 314 (Lt.Cdr. A.F. Collett, DSC, RN), sighted smoke and the mast of a ship proceeding to the north-east at a fairly high speed close inshore. The target was way too far off to be attacked. (4)

6 Feb 1943
At 1650A/6, when west of Kristiansund, Norway, HMS P 314 (Lt.Cdr. A.F. Collett, DSC, RN), picked up very loud HE at 320 revs which passed directly overhead. HMS P 314 then went to periscope depth but nothing was sighted in the very bad weather / visibility. HE faded out soon afterwards.

At 2027A/6, HMS P 314 received Capt. S 9's signal timed 1431A/6 recalling her from patrol. Course was then set to proceed to Lerwick. (4)

8 Feb 1943
Around 0950A/8, HMS P 314 (Lt.Cdr. A.F. Collett, DSC, RN) ended her 1st war patrol at Lerwick. (4)

[The date she is undocked is currently not known to us as no logs are available for this period]. (2)

7 Mar 1943
Around 1900A/7, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Holy Loch for Gibraltar. She is to join the Mediterranean Fleet.

She left Holy Loch in company with HMS Ultor (Lt. G.E. Hunt, DSC, RN). They were escorted until around 1630A/7 by HMS Cutty Sark (Cdr.(Retd.) R.H. Mack, RN) when they all parted company off Round Island, Scilly Islands.

[As there is no log available of HMS Tactician for this period no map can be displayed.] (4)

18 Mar 1943
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) arrived at Gibraltar from Holy Loch. (4)

28 Mar 1943
Around 1600A/28, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Gibraltar for her 2nd war patrol (1st in the Mediterranean). She was ordered to patrol off Southern France.

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

(4)

13 Apr 1943
Around 0720A/13, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) ended her 2nd war patrol (1st in the Mediterranean) at Algiers.

The patrol had been uneventful, only during the period of 2 to 7 April, when near Cape Bear, an A/S trawler was constantly patrolling the area. (4)

23 Apr 1943
Around 1830A/23, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Algiers for her 3rd war patrol (2nd in the Mediterranean). She was ordered to patrol east of Corsica.

[As there is no log available for this period no map can be displayed.] (4)

27 Apr 1943
At 1755A/27, when in position 078° - Cape Corse - 14 nautical miles, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted a trawler approaching Bastia on a course of 210° at 10 knots.

This was probably just a fishing vessel as there had only three auxiliary submarine chasers been operating off Bastia on that day;
Lido, between 0300 and 0845 hours.
Nuovo S. Rita between 0300 and 0915 hours.
Teti II between 0250 and 0930 hours.
Thus none of them were out at the time of this sighting.

Note: HMS Tactician arrived too late in the area as a convoy made up of the transports Ercole (Italian, 5027 GRT, built 1904), Dominante (Italian, 1100 GRT, built 1891), S. Chiara (Italian, 1199 GRT, built 1889), motor tanker Abruzzi (Italian, 680 GRT, built 1897) and schooner Florastella (Italian, 304 GRT, built 1915) escorted by the Italian torpedo boat Giuseppe La Masa sailed from Bastia at 0535B/27 for Leghorn where they arrived at 1518B/27. ? (4)

28 Apr 1943
At 0630A/28, when in position 096° - Bastia Citadel - 7 nautical miles, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted a small patrol craft leaving Bastia at high speed. She stopped close astern presumably to listen with hydrophones so Lt.Cdr. Collett took HMS Tactician to 90 feet. No A/S transmissions were heard and also no more HE was heard. On return to periscope depth 20 minutes later all was clear.

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

29 Apr 1943
At 0708A/29, when in position 072° - Bastia Citadel - 6 nautical miles, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) two small vessels were seen approaching from the southward about 4 nautical miles from the shore. Both had several guns mounted. Also on was heard transmitting on Asdics.

At 1228A/29, a small ship of about 800 tons approaching Bastia but it was too far to the south to be attacked before it entered the harbour.

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

30 Apr 1943
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) fired three torpedoes against the French passenger/cargo vessel Cap Corse (2444 GRT, built 1929) north-east of Bastia, Corsica. No hits were obtained.

The Cap Corse was on a trip from Bastia to Nice escorted by an Italian seaplane of the 146^Squadriglia. She reported being missed by three torpedoes.

0615A/30 - While in position 067° - Cape Sagro - 3.5 nautical miles a French merchant vessel of approximately 2000 tons was sighted steering north at a speed of about 11 knots. Started attack.

0624A/30 - Fired three torpedoes. No hits were obtained.

0630A/30 - Withdrew to the south. (4)

4 May 1943
At 0630A/4, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) observed two enemy trawlers being present in Giglio Island harbour.

At 0835A/4, a small steamer was seen leaving Port San Stefano (Monte Argentario) for Giglio. She passed quite close proceeding at 10 knots. She appeared to have a 3" gun mounted forward. She was seen to return around 1100A/4.

At 1220A/4, a merchant vessel of about 1500 tons leaving Port San Stefano to the northward. She was not escorted. HMS Tactician was too far to the south to be able to attack.

At 1700A/4, HMS Tactician surfaced and proceeded to the north of Giglio Island to charge. (4)

5 May 1943
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sank the Italian auxiliary patrol vessel V17 / Pia (385 GRT) with gunfire about 10 nautical miles west of Grosseto, Italy in position 42°34'N, 10°45'E.

0747A/5, near Cape Argentario, a three-funnelled Italian torpedo boat, thought to be of the Abba-class passed northward. At the same time three southbound schooners were seen. They could not be attacked.

This was probably the torpedo boat Giuseppe La Masa who sailed at 2320B/4 from Olbia for Leghorn where she arrived at 1020B/5. At 0535B/5, she was off Monte Cristo.

1830A/5 - In position 42°34'N, 10°45'E sighted a large three-masted schooner. Decided to attack with the 4" gun.

1911A/5 - Surfaced at a range of 2500 yards and sank the schooner with gunfire. 29 Rounds were used.

1918A/5 - Submerged as the target was now well ablaze from end to end.

1955A/5 - The schooner was seen to sink. (4)

6 May 1943
At 2030A/6, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) left patrol to return to Algiers as ordered in Capt. S 8's signal timed 1148A/2. (4)

11 May 1943
Around 0930A/11, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) ended her 3rd war patrol (2nd in the Mediterranean) at Algiers. (6)

22 May 1943
Around 1830A/22, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Algiers for Malta.

[As there is no log available for this period no map can be displayed.] (7)

28 May 1943
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) arrived at Malta. (5)

3 Jun 1943
Around 1700B/3, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Malta for her 4th war patrol (3rd in the Mediterranean). She was ordered to patrol in the Adriatic.

[As there is no log available for this period no map can be displayed.] (4)

8 Jun 1943
At 1530A/8, when in position 41°13'N, 17°46'E (085° - Bari Lighthouse - 42 nautical miles), HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted smoke, masts and a funnel of a merchant vessel bearing 340°. HMS Tactician increased to full submerged speed and endeavoured to close but unfortunately on hour later the attack had to be broken off as it was obvious the range could not be closed to more then 5 nautical miles. Enemy course was about 105° at about 9 knots and it is thought this ship was en-route from Bari to Durazzo.

This must have been the Italian transport Mariannina (1317 GRT, built 1885) which sailed from Bari at 0900B/8, proceeding at 5.5 knots to Durazzo where she arrived at 0730B/9. (4)

9 Jun 1943
At 1226A/9, (no position given in the patrol report, but must be reasonably close to Bari) HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighed another merchant vessel’s masts and funnel to the south. An attack was started but the ship soon disappeared from sight.

This was most likely the transport Toscana (Italian, 9442 GRT, built 1923) which sailed from Bari at 1100B/9 for Naples. Her speed was given as 8 knots. (4)

10 Jun 1943
At 0910A/10, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted two auxiliary caique type minesweepers sweeping the channel to Bari from the harbour entrance to 060° - 4 nautical miles.

At 1500A/10, a ship, thought to be a small tanker of about 900 tons, was seen leaving Bari Harbour. She approached very slowly at 6 knots steering a steady course until 1545A/10 when she altered course placing HMS Tactician about 4000 yards right ahead of the target. HMS Tactician ran out on a 90° track at full speed for 5 minutes to the southward and after a quick look through the periscope it was seen that HMS Tactician was still right ahead of the target so full speed was run for another 6 minutes.

At 1615A/10, it was seen that the target had altered 90° to starboard. So HMS Tactician also commenced to turn to starboard to get on track again. It was then seen that HMS Tactician was now right ahead of an escort vessel approaching from 120° and from two merchant ships from 060°. HMS Tactician had just time to go deep.

On returning to periscope depth it was seen that HMS Tactician was hopelessly out of place to attack and that two more escorts were present. The ship which had originally been sighted was now thought to be some sort of armed boarding vessel. She had awaited the convoy at the end of the swept channel. The convoy now entered Bari.

The tug Talamone sailed from Bari at 0910B/10, the schooner Ortensia sailed at 1235B/10 and the passenger ship Merano (Italian, 3705 GRT, built 1909) sailed from Bari at 1325B/10. None of these match the description given by Lt.Cdr. Collett. (4)

11 Jun 1943
At 0510A/11, off Bari, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted a hospital ship passing at a range of about 2000 yards. She entered Bari at 0600A/11 having been met at the entrance to the swept channel by the 'armed boarding vessel' which had also been seen the day before.

At 0810A/11, a heavily laden schooner was sighted. She passed only 100 yards off and entered Bari in company with the 'armed boarding vessel'. Lt.Cdr. Collett considered gun action but just managed to resist the temptation and wait for better targets to appear.

The hospital ship Aquileia (Italian, 9448 GRT, built 1914) arrived at Bari at 0835B/11 (the time is a bit different). She was bringing wounded from Meline (Yugoslavia).

Note: At 0445B/11, the tanker Cesco (Italian, 6161 GRT, built 1917) escorted by the torpedo boat Giuseppe Missori sailed from Bari for Valona. It is a bit strange that Tactician missed them, perhaps she must have been withdrawing from the coast to charge her batteries.
At 1425B/11, the minesweeper RD 22 arrived at Bari from Brindisi.
At 1430B/11, the fishing vessels Nettuno, Sacro Cuoro di Gesù, Salvatore and Avvenire arrived at Bari from Brindisi.

Nothing could be found on the identity of the schooner sighed by HMS Tactician at 0810A/11. (4)

12 Jun 1943
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) damaged the large Italian motor schooner Bice (1098 GRT, built 1902) with gunfire 5 nautical miles north-east of the Bari lighthouse.

According to Italian sources Bice was on a trip from Durazzo to Bari and was being led in by the auxiliary (former pilot vessel) F 122 / Letizia. The latter opened fire on the submarine with a small gun. Bice was only slightly damaged but the crew had abandoned ship and Letizia had a hit on the balustrade holding the compass causing only minor damage but several shells fell very close to her. By this time coastal batteries had opened fire on the submarine which submerged. Letizia followed up and dropped four depth-charges then the crew reboarded Bice and, towed by Letizia, she reached Bari at 1600 hours. Marina Bari had immediately ordered the torpedo-boat Giuseppe Missori, the auxiliary minesweeper B 296 / S.Nicola I (B.296) and the motorboat 23 to hunt the submarine.

0915B/12 - The usual 'armed boarding vessel' was seen to come to the end of the swept channel. Two hospital vessels in the harbour were seen to have steam so it was thought that they were about to leave robbing HMS Tactician from yet another attack possibility.

1220B/12 - Tactician surfaced and engaged a large schooner with gunfire from 2200 yards. The schooner was escorted by an armed vessel that was approximately 4500 yards away.

The first round was fired only 24 seconds after Tactician passed 10 feet. The fourth and fifth round were a hits on the schooners hull. The crew of the schooner abandoned ship.

About 5 minutes into the action the armed vessel opened fire on Tactician which now shifted target. Several hits were obtained on this vessel with one of the hits knocking out it's gun. The enemy vessel eventually fled towards Bari harbour.

Target was now shifted back to the schooner again that soon started to settle after several more hits.

1234B/12 - Tactician was taken under fire by shore batteries forcing Lt.Cdr. Collett to dive and break off the action.

1320B/12 - Twenty-three depth charges were dropped but these caused no damage. (4)

14 Jun 1943
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) torpedoed and damaged the transport Rosandra (Italian, 8035 GRT, built 1921) off the coast of Albania in position 40°14'N, 19°28'E.

Rosandra was on a trip from Prevesa to Valona escorted by the auxiliary Rovigno. She was hit by two torpedoes and taken in tow by the minesweeper Monfalcone but the ship sank the following day. Six were killed, Rovigno picked up 173 survivors.

0637B/14 - While in position 261° - Sazan Island lighthouse - 6 nautical miles sighted masts of a ship leaving Valona northbound. HMS Tactician was not in a position to attack.

0755B/14 - Sighted two minesweepers sweeping between Cape Linguetta and Sazan Island into Valona Bay.

1610B/14 - When in position 155° - Cape Linguetta - 15 nautical miles, a northbound merchant vessel of 7600 tons was sighted close inshore. An attack was started.

1641B/14 - Four torpedoes were fired when range was closed to 2200 yards. Although no escort was seen during the setup of the attack there was one that closed Tactician and forced her deep shortly after firing the torpedoes.

Before the last torpedo exploded a depth charge was dropped that was very close. Within 10 minutes 16 more depth charges were dropped with three of them even closer then the first one. No real damage was done and the escort lost contact soon after.

2215B/14 - Surfaced and set course to leave patrol. (4)

15 Jun 1943
Around 2100B/15, in position 39°09'N, 18°15'E, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted a submarine 7 to 8 nautical miles away bearing 310° steering approximately northwards silhouetted against the sunset. Closed and brought all eight forward torpedo tubes to the ready. The target could not be identified definitely as it was rapidly getting darker.

At 2115B/15, the target could no longer be seen in the darkness so the attack was broken off and course was set to the southward. An enemy report was passed by W/T at 2220B/15.

As this sighting was on the edge of the operating area of HMS Unbroken (Lt. B.J.B. Andrew, DSC, RN), Lt.Cdr. Collett did not attack immediately.

This was the Italian submarine Atropo returning to Taranto from a supply mission to Lampedusa. She arrived at Taranto around 0820B/16. (4)

18 Jun 1943
Around 1130B/18, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) ended her 4th war patrol (3rd in the Mediterranean) at Malta. (4)

3 Jul 1943
Around 2200B/3, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Malta for her 5th war patrol (4th in the Mediterranean). She was ordered to patrol in the Gulf of Taranto as part of a patrol line of five submarines to provide cover during Operation Husky, the Allied landings on Sicily.

[As there is no log available for this period no map can be displayed.] (4)

10 Jul 1943
At 0600B/10, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) left the Gulf of Taranto as she was now ordered to patrol in the Adriatic south of a line 132° - Pelagosa Island and west of 18°53'E. (4)

11 Jul 1943
At 2345B/11, when near Brindisi, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) had to dive as an unidentified patrol vessel was sighted bearing 315° at a range of 4 miles and closing. HMS Tactician surfaced an hour later to find nothing in sight. (4)

12 Jul 1943
At 1325B/12, when patrolling off the Brindisi swept channel, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighed two minesweepers sweeping the swept channel out of Brindisi thereby giving away its exact location. [We have been unable to identify these vessels.]

At 1820B/12, two three-masted schooners were and two three-masted caiques were seen leaving Brindisi through the swept channel. They were escorted by an armed trawler.

This may have been schooners out of the following which had sailed from Brindisi at 1730B/12; Maria Giuseppina, Tacito and Vi Dirò.

At 1945B/12, the trawler was seen to return to the harbour. The sailing vessels were not attacked as it was not considered wise to compromise the patrol position so early after having arrived off Brindisi. [We have been unable to identify this trawler.] (4)

13 Jul 1943
At 1230B/13, when patrolling off the Brindisi swept channel, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted a tanker of about 6000 tons leaving Brindisi. She was escorted by a destroyer and an aircraft. Instead of proceeding to the end of the swept channel they altered course to the southward when five miles from the shore. The destroyer turned back to Brindisi and the tanker proceeded unescorted. The range could not be closed to less then 12000 yards and it was possible to surface and give chase as the destroyer was still in sight and the aircraft was also still in the area.

According to Italian sources, no tanker or destroyer left Brindisi on this day. [Also it would be very foolish for the Italians to send a 6000-ton tanker unescorted southward with all the armada of operation Husky in place.] (4)

14 Jul 1943
At 1230B/14, when patrolling off the Brindisi swept channel, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted two small merchant vessels in ballast and an escorting destroyer entering the swept channel from the seaward. They passed at a range of 3000 yards but the attack was broken off when it was seen that the merchant vessels were only of about 1100 and 600 tons respectively. As they were in ballast and small it was considered that torpedoes would most likely run underneath them.

The transports Pugliola (Italian, 2074 GRT, built 1917) and Costante (Italian, 869 GRT, built 1901) escorted by the Italian auxiliary Rovigno (451 GRT, built 1941) arrived at Brindisi at 1450B/14 and must have been the ships sighted. (4)

16 Jul 1943
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) fires six torpedoes against the Italian submarine Luigi Settembrini that was about to enter Brindisi harbour. No hits were obtained.

Settembrini was on passage from Pola to Brindisi. The Italian submarine observed two torpedo tracks astern, one at about 200 meters and another just only 15 meters.

Later on this day she set course to return to the Gulf of Taranto as ordered by Captain S.10.

1300B/16 - Sighted a trawler leaving Brindisi and proceeding up to swept channel.

1350B/16 - The trawler was seen to proceed back towards Brindisi.

1356B/16 - It was now seen that a submarine was following the trawler up the swept channel. Started attack.

1403B/16 - Fired six torpedoes. No hits were obtained. Tactician now set course to retire from the Adriatic as had been ordered in Capt. S 10's signal timed 0630B/16. (4)

18 Jul 1943
At 0001B/18, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) established patrol in the Gulf of Taranto. (4)

22 Jul 1943
At 0010B/22, in the Gulf of Taranto, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) was forced to dive for an approaching motor torpedo boat which was seen approaching from the southward and had closed to 1000 yards.

Later this day HMS Tactician left parol to proceed to patrol as ordered in Capt. S 10's signal timed 1310B/16 and Capt. S 1's signal timed 1609C/21. (4)

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 which had not reported any sighting at this time.

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. (8)

27 Jul 1943
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) ended her 5th war patrol (4th in the Mediterranean) at Beirut. (4)

8 Aug 1943
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Beirut for Port Said where she is to be docked.

HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) is docked at Port Said. (9)

17 Aug 1943
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) is undocked. (9)

18 Aug 1943
Around 1800C/18, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Port Said for her 6th war patrol (5th in the Mediterranean). She was ordered to patrol in the Aegean and to perform a special operation. (4)

21 Aug 1943
At 1816C/21, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) received Capt. S 1's signal timed 1531C/21 ordering her to proceed immediately to patrol in the Trikeri Channel and postpone her special operation. Course was set accordingly and patrol was established in the Trikeri Channel by 0230C/23. The transport Gerda Toft (German (former Danish), 1960 GRT, built 1930) was expected to proceed there from the Dardanelles. (10)

26 Aug 1943
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) carries out special operation ' Bromfield '. Around 2330C/26, the submarine landed three Greek agents on the north side of Karalades Bay (Euboa). On completion of the special operation course was set to patrol off the Dardanelles as ordered in Capt. S 1's signal timed 2117C/25. (4)

28 Aug 1943
At 1955C/28, near the entrance to the Dardanelles, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) was passed close ahead by two high speed craft proceeding northwards. It was too dark to identify them but the were transmitting on Asdics. It was thought it might be torpedo boat or E-boats probably proceeding northwards to pick up a ship coming from the Dardanelles. This may have been the Italian torpedo boats Solferino and Calatafimi proceeding to the Dardanelles to meet the tanker Celeno (Italian, 3741 GRT, built 1899) and then escort her to Piraeus.

At 2055C/28, HMS Tactician surfaced and immediately sighted a dark object a mile to the south so she dived again to avoid being sighted.

At 2140C/28, HMS Tactician surfaced again.

At 0030C/29, what is thought to be a patrol vessel was sighted close ahead. HMS Tactician dived but was probably sighted as the enemy circled round the submarine slowly while using Asdics. The enemy than passed almost directly overhead and HE could be heard all through the boat for about 10 minutes. HMS Tactician was kept down and most likely around this time the expected tanker Celeno passed through the area. (4)

29 Aug 1943
At 2131C/29, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) received Capt. S 1's signal timed 1058C/29 ordering her to patrol in the southern Aegean. Course was set to comply. (4)

1 Sep 1943
At 2117C/1, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) received Capt. S 1's signal timed 1104C/1 ordering her to leave patrol proceeding either via the north of Rhodes or through the Scarpanto Strait. Course was then set to proceed via the north of Rhodes. (4)

5 Sep 1943
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) ended her 6th war patrol (5th in the Mediterranean) at Beirut. (4)

18 Oct 1943
Around 2130FG/18, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Colombo for her 7th war patrol (1st in the Far East). She was ordered to patrol off Penang, Malaya. She is also to carry out a special operation.

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

(4)

26 Oct 1943
From 26 to 28 October 1943, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) carries out special operation MISSIVE I.

[So far no report of this special operation, which took place in the Pengang area, has been found, the first part of this operations appears to have been a reconnaissance of the NW coast of Pulo Langkawi, the second part may have been to make contact with a sampan but it is just a guess]. (4)

27 Oct 1943
At 1500FG/27, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted the masts and funnel of a small ship entering Penang by the south entrance.

At 1950FG/27, a vessel was seen to the north at a range of 6000 yards which showed a large bow wave. The night was too dark to see the silhouette of the contact and the Officer of the Watch dived at once as it was too late to make an attack. HE was picked up on the Asdic which gave a speed of 15 to 16 knots for the contact. It was thought it may have been an enemy submarine returning from patrol.

[No enemy submarine arrived at Penang from patrol on this day.] (12)

28 Oct 1943
At 0800FG/28, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted the masts and funnel of a small coaster leaving Penang to the eastward. She passed more then 6 nautical miles to the south of HMS Tactician so an attack was not possible.

At 2100FG/28, HMS Tactician closed the coast to carry out the second part of special operation Missive I. This was completed at 2330FG/28. (4)

30 Oct 1943
At 0830FG/30, when on patrol off the northern entrance into Penang, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted what is thought to be a small Japanese submarine chaser entering Penang from the westward at 15 knots. (4)

31 Oct 1943
At 2300FG/31, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) left patrol off Penang to return to Colombo. (4)

27 Nov 1943
Around 2000FG/27, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Colombo for her 8th war patrol (2nd in the Far East). She was ordered to patrol off the West coast of Siam. She is also to carry out two special operations (Missive II and Pritchard).

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

(4)

4 Dec 1943
From 4 to 7 December, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) tries to carry out the first (Operation ' Missive II ') of the two special operations she was to carry out during this patrol. The special operation was not a success and had to be abandoned.

On 4 December Tactician carried out a preliminary reconnaissance of the area off Langkawi.

On 5 and 7 December Tactician waited for a junk with several secret agents to show up off Langkawi. The junk however did not show up at the rendezvous.

On 6 December, which was not a rendezvous day, a junk was boarded off Pulau Rebak. After taking off the papers the junk, which had a crew of four Chinese, and was carrying a cargo of rubber and tea from Lamut to Kantan, was released. The junk had called at Penang four days previously and an attempt was made to interrogate the crew but they spoke no Malay (there was a Malay speaking officer on board HMS Tactician for the special operations). (4)

9 Dec 1943
From 9 to 16 December, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) tries to carry out the second of the two special operatives she was to carry out during this patrol. Like the first special operation this one was also not a success and had to be abandoned late on 16 December.

Attempted to make contact with agent Luang Pradit without success about 30 nautical miles north of Phuket, Siam (Operation ' Pritchard '. Nothing of the agent was however sighted. At 2200FG/12, a group of two (Captain Read and Lieutenant Whitelaw) were landed by Folbot to make a shore reconnaissance. They also sighted nothing and were back on board HMS Tactician after four hours. (4)

16 Dec 1943
At 2100FG/16, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) left patrol to proceed to Trincomalee. (4)

20 Dec 1943
Around 1400FG/20, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) ended her 8th war patrol (2nd in the Far East) at Trincomalee.

She was escorted in by a trawler [identity not known] which she had met around 0730FG/20. (14)

5 Jan 1944
Around 0900FG/5, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Trincomalee for her 9th war patrol (3rd in the Far East). She was escorted out by the Italian sloop Eritrea on which she also made two practice attacks. They parted company around 1500FG/5.

HMS Tactician was ordered to patrol off the north coast of Sumatra. She is also to carry out a special operation (Operation Versatile). (15)

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

9 Jan 1944
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) encounters a submarine about 40 nautical miles south-east of Great Nicobar Island in position 06°21'N, 93°22'E. It was not possible to identify the submarine. As it might have been a British submarine returning to Trincomalee it was not attacked.

0030FG/9 - In position 06°21'N, 93°22'E the Officer of the Watch dived for a submarine 3000 yards ahead. The submarine was easily picked up in the high power periscope. All bow tubes were brought to the ready. It was however not possible to positively identify the submarine as enemy. It appeared she had a large conning tower or tower and gun combined and a rising bow, just like the 'T-class'. The submarine was therefore not attacked.

No British submarine was expcted in this area at the given time but it was always possible that a submarine on patrol had sustained damage and was returning early unable to signal her intention to do so.

The Japanese submarine I-165 (offsite link) had departed Penang on 7 January 1944 for a patrol in the Indian Ocean and it is quite likely that she was the submarine Tactician encountered. (4)

12 Jan 1944
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) conducted special operation Versatile.

In the afternoon of the 12th a periscope reconaissance of the area was made.

At 2210FG/12, HMS Tactician landed three agents in two 'Recce' boats north-west of the Bedagei River (near position 03°36.4'N, 99°18.6'E). After the agents made a signal that they had landed safely at 0100FG/12, HMS Tactician withdrew to patrol off the north coast of Sumatra between Diamond Point and Sabang the following morning. (4)

14 Jan 1944
At 2240FG/14, to the west of Diamond Point, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted three small junks proceeding eastwards close inshore. They were not attacked. (15)

16 Jan 1944
At 1445FG/16 [this time is according to the log, the patrol report gives the time as 1145FG/16 but this might be a typo as we believe the log to be the correct entry], off the north coast of Sumatra about midway between Sabang and Diamond Point, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighted three small junks proceeding westwards close inshore. They were not attacked. (15)

17 Jan 1944
At 0530FG/17, when in position 05°29'N, 96°30'E, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) first detected with her hydrophones and later sighted an unescorted merchant vessel bearing 040° which was thought to be a seaplane tender of the Kagu Maru-class to the but she passed out of range as HMS Tactician was patrolling on the inshore route. Enemy course was 295° at 16 knots.

[It is possible that the Kiyokawa Maru (offsite link) may have been in this area.] (15)

22 Jan 1944
Around 0230FG/22, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) left patrol to return to Trincomalee as ordered in Capt. S 4's signal timed 0855Z/19. (15)

26 Jan 1944
Around 1300FG/26, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) ended her 9th war patrol (3rd in the Far East) at Trincomalee. (4)

10 Feb 1944
Around 0720FG/10, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Trincomalee for her 10th war patrol (4th in the Far East). She was ordered to patrol in the Malacca Straits. She is also to carry out a special operation (operation Mullet).

On departure from harbour gunnery exercises were carried out on a target that was being towed by HMS Tewara (T/Lt. J.G.A. Curtis, RNVR). On completion of these exercises HMAS Napier (Lt.Cdr. A.H. Green, DSC, RAN) joined at 0910FG/10 to escort the submarine out.

At 1145FG/10, HMAS Napier parted company to return to Trincomalee. (4)

10 Feb 1944
For the daily and attack positions of HMS Tactician during her 10th war patrol see the map below.

16 Feb 1944
During the afternoon, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) carries out periscope reconnaissance of the west and north coasts of Pulau Butang and Pulau Rawi. A suitable landing spot for the upcoming special operation 'Mullet' was sighted. (16)

17 Feb 1944
During 17 and 18 February 1944, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) tried to intercept a suitable junk that could be used for special operation 'Mullet'. She however failed to intercept one. (4)

20 Feb 1944
At 0130 hours HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) boards a junk near Langkawi. The junk however proved to be useless for the special operation. The crew was so frightened of the Japanese that they refused to co-operate with the British. The junk was released. The next day Tactician was ordered to patrol elsewhere. (17)

21 Feb 1944
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) attacks a Japanese submarine south of Langkawi in position 05°53'5N, 99°46'2E. Five torpedoes were fired but these missed.

The Japanese submarine RO-111 (offsite link) returned to Penang from patrol in the Indian Ocean on 23 February 1944 but it is unlikely she was already so close to Penang on this day and also her maximum speed was less then the speed the target had. Possibly a boat based at Penang had been on exercises before departing on patrol.

[According to the patrol report this attack took place on 20 February 1944 but according to the submarines log it took place on 21 February 1944. We think the log is correct and this seems to be confirmed in the Admiralty war diary summaries (file ADM 199/2290).]

0725FG/21 - Sighed a submarine bearing 260° at a range of 4 nautical miles. The submarine was thought to be Japanese steering a course 125° towards Penang.

0729FG/21 - Five torpedoes were fired from 5000-6000 yards. All five torpedoes missed the target. It was intended to fire eight torpedoes but when the 5th torpedo was fired it was realised that the targets speed was underestimated. The enemy speed had been estimated as being 15 knots. (4)

23 Feb 1944
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) lands the 'Mullet' party as during the past days no suitable junk to put them on had been found. The party were sighted by local fishermen and decided to return to the submarine. As it was becoming light they had to wait till after dark before they could return.

0330FG/23 - The 'Mullet' party left Tactician in two Folbots to land on Langkawi. They were equipped with stores for six days. As they landed they ran into a group of local fishermen. They endeavoured to return to Tactician but there was insufficient time before daylight so they landed after all. They hoisted a signal that they were returning after dusk so Tactician remained in the area.

Shortly after dark the party departed the beach for Tactician but in the dark they missed the submarine. Only after Tactician sounded her siren they realised they were to the seaward of the submarine. They finally returned at 2230FG/23. Tactician then set course to patrol to the west of the Aroa Islands.

Tactician was later ordered by signal (Capt. S 4's 1815Z/22) to abandon the operation. (18)

29 Feb 1944
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sank a small merchant vessel with gunfire and a torpedo in the Malacca Straits in position 03°03'N, 100°18'E.

1315FG/28 - In position 02°49'N, 100°22'E sighted a small merchant vessel steaming north.

1430FG/28 - Tactician surfaced astern of the target and opened fire from 1200 yards. A gun on the stern of the enemy was immediately put out of action. A large number of men, thought to be passengers, were seen to jump overboard. Fire was checked to give them the chance to abandon ship but the enemy sent over a hail of machine gun fire so fire was reopened. The engines were put out of action and the enemy ship stopped. Tactician then altered course to get to the front of the enemy to hole her forward. This unfortunately opened up the arcs of the enemy's forward gun. A further 15 rounds were fired nearly all scoring hits. The enemy's fire was now becoming more accurate. Tactician now went under the enemy's stern again. After firing more rounds resulting in more hits the enemy still did not appear to be sinking so it was decided to dive to open the range and finish the ship off from out of range from her gun.

1502FG/28 - Sighted smoke approaching from the north-east, which soon proved to be a northbound tanker of about 800 tons. Course was immediately altered to intercept. Meanwhile the original target had settled aft, it's engine room was obviously completely flooded and it was hoped she would sink without further persuasion.

1800FG/28 - The tanker was now out of sight.

1830FG/28 - Surfaced to intercept. Proceeded northwards. The tanker was however not seen again. Proceeded back to the area of the original action.

Before dawn (on the 29th) the scene of the action was approached with caution. The target was seen to be still afloat and stopped. 0509FG/29 - Commenced a submerged approach. As the periscope was seen and being fired upon it was decided to attack with a torpedo.

0730FG/29 - Fired a torpedo from 700 yards but it ran under. A second torpedo was therefore fired that hit the target just forward of the bridge and the ship sank immediately in position 03°03'N, 100°18'E.

1830FG/29 - Left patrol to return to Trincomalee. (4)

7 Mar 1944
Around 1415FG/7, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) ended her 10th war patrol (4th in the Far East) at Trincomalee. (4)

13 Mar 1944
Around 1815FG/13, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Trincomalee for Colombo. (19)

15 Mar 1944
Around 0845FG/15, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) arrived at Colombo. (19)

17 Mar 1944
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) is docked in the outer graving dock at Colombo. (19)

25 Mar 1944
HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) is undocked. (19)

27 Mar 1944
Around 1815FG/27, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Colombo for Trincomalee. (19)

29 Mar 1944
Around 1040FG/29, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) arrived at Trincomalee. (19)

31 Mar 1944
Around 1915FG/31, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) departed from Trincomalee for her 11th war patrol (5th in the Far East). She was ordered to patrol near Phuket on the West coast of Siam. She is also to carry out a special operation (Operation Corton II).

HMS Tactician was escorted out by HMS Maid Marion (T/Lt. F.R. Crawford, RNVR). They parted company around 2330FG/31. (4)

31 Mar 1944
For the daily positions of HMS Tactician during her 11th war patrol see the map below.

5 Apr 1944
From 5 to 9 April 1944, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) carries out special operation Corton II.

At dawn Tactician arrived in the vicinity of Elphinstone Island. The north-west coast was then closed. Submerging to within 10 cables.

1000FG/5 - A yellow flag was observed near the end of the point to the southward of the bay on the west side of Elphinstone Island in position 12°19.2'N, 97°56.7'E.

1600FG/5 - The signal (yellow flag) was removed. Tactician remained in close proximity to the shore after dark.

0100FG/6 - The letter 'R' was flashed twice from the end of the point.

0120FG/6 - The whole 'Corton I' party (which had been landed on 5 February 1944 by HMS Trespasser (Lt.Cdr. R.M. Favell) arrived on board. Captain Green, the leader of the party seemed very fit but three of his men were sick, two of which had malaria. Captain Green gave a favourable report of his camp and there were no indications that it had been compromised. Four dinghies were therefore loaded with stores and sent ashore at 0230FG/6 as were four Folbots with the whole of the 'Corton II' party, Captains Green and Maitland and one other rating.

HMS Tactician spent 6 April 1944 submerged within 4 nautical miles from the landing place until ...

2200FG/6 - Closed the landing zone with all remaining stores on deck and all boats rigged and ready for launching.

On return, Captain Green reported that a large motor launch with 15 occupants had landed early in the afternoon on the north-west point of the land, which is part of Elphinstone Island and not a separate island as was shown on the chart. This was less then two nautical miles away and looked very suspicious. After debate it was decided that if it was an enemy patrol it was just a regular one and it could even have been locals. It was also decided to go ahead with landing stores although by now only one trip could be made before dawn.

During the 7th, Tactician again conducted a close submerged patrol but nothing was seen of the reported motor launch.

During the night of 7/8 April the remaining stores were landed. All stores were reported to be safely ashore.

At 0001FG/9, HMS Tactician left the area and set course for her patrol area near Phuket. (16)

9 Apr 1944
At 2300B/13, in position 08°52'N, 98°08'E, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) sighed smoke and three small dark objects bearing 080° at a range of 7 nautical miles. HMS Tactician then closed at full speed and endeavoured to head off the ship before it reached the southern end of Salang Island. The ship was however too fast and could not be overtaken. No more than smoke and the ships funnel could be seen. (4)

16 Apr 1944
At 0100FG/16, HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN) left the Phuket area to proceed towards the vicinity of Sabang for air/sea rescue duties as had been ordered in Capt. S 4's signal timed 1209Z/15.

While en-route HMS Tactician encountered HMS Taurus (Lt.Cdr. M.R.G. Wingfield, DSO, DSC and Bar, RN) in position 06°37'N, 96°18'E.

HMS Tactician arrived in her assigned area at midnight during the night of 16/17 April 1944. (4)

16 Apr 1944

Operation Cockpit

Carrier raid against Sabang by the Eastern Fleet.

On 16 April 1944 the Eastern Fleet put to sea from Trincomalee, Ceylon in two task forces;
Task Force 69, which was made up of the battleships HMS Queen Elizabeth (Capt. H.G. Norman, CBE, RN, flying the flag of Admiral J.F. Somerville, KCB, KBE, DSO, RN, C-in-C Eastern Fleet), HMS Valiant (Capt. G.E.M. O’Donnell, DSO, RN), Richelieu (Capt. Lambert), the light cruisers HMS Newcastle (Capt. P.B.R.W. William-Powlett, DSO, RN, flying the flag of Rear-Admiral A.D. Read, CB, RN), HMS Nigeria (Capt. S.H. Paton, RN), HMS Ceylon (Capt. G.B. Amery-Parkes, RN), HMNZS Gambia (Capt. N.J.W. William-Powlett, DSC, RN), HrMs Tromp (A/Capt. F. Stam, RNethN) and the destroyers HMS Rotherham (Capt. F.S.W. de Winton, RN), HMS Racehorse (Cdr. J.J. Casement, DSC, RN), HMS Penn (Lt.Cdr. J.H. Swain, DSO, DSC, RN), HMS Petard (Lt.Cdr. R.C. Egan, DSO, RN), HMAS Quiberon (Cdr. G.S. Stewart, RAN), HMAS Napier (Lt.Cdr. A.H. Green, DSC, RAN, with Commodore S.H.T. Arliss, DSO, RN, on board), HMAS Nepal (Lt.Cdr. J. Plunkett-Cole, RAN), HMAS Nizam (Cdr. C.H. Brooks, RAN), HrMs Van Galen (Lt.Cdr. F.T. Burghard, RNethN).

Task Force 70, which was made up of the battlecruiser HMS Renown (Capt. B.C.B. Brooke, RN, flying the flag of Vice-Admiral A.J. Power, KCB, CVO, RN, second in command of the Eastern Fleet), the British aircraft carriers HMS Illustrious (Capt. R.L.B. Cunliffe, RN, flying the flag of Rear-Admiral C. Moody, CB, RN), USS Saratoga (Capt. J.H. Cassady, USN), heavy cruiser HMS London (Capt. R.V. Symonds-Tayler, DSC, RN) and the destroyers HMS Quilliam (Capt. R.G. Onslow, DSO and 2 Bars, RN), HMS Quadrant (Lt.Cdr. W.H. Farrington, RN), HMS Queenborough (Cdr. E.P. Hinton, DSO and Bar, MVO, RN), USS Cummings (Cdr. P.D. Williams, USN), USS Dunlap (Cdr. C. Iverson, USN) and USS Fanning (Lt.Cdr. J.C. Bentley, USN).

During the forenoon of the 17th the four 'N' class and two 'P' class destroyers of Force 69 were fuelled by HMS Newcastle, HMS Nigeria, HMS Ceylon, HMNZS Gambia. The three 'Q' class destroyers from Force 70 were fuelled by HMS Renown and HMS London.

On the 18th HMS Ceylon and HMNZS Gambia were transferred from Force 69 to Force 70 to bolster the latters AA defence. (On the 19th HMS Nigeria replaced HMS Ceylon in this force as HMS Ceylon had problems with one shaft and could only make 24 knots.) At sunset Force 70 was detached so as to arrive at the flying off position for the aircraft at 0530/19.

At 0530/19 the carriers launched 46 bombers and 37 fighters (17 Barracudas and 13 Corsairs from HMS Illustrious and 11 Avenges, 18 Dauntless and 24 Hellcats from USS Saratoga) to attack Sabang and nearby airfields. Besides that 12 fighters were launched to patrol overhead of both Task forces.

The enemy was taken completely by surprise and 24 Japanese aircraft were destroyed on the ground. Only 1 fighter, a Hellcat from the Saratoga, was lost on the Allied side and it's pilot was rescued out of the water by the British submarine HMS Tactician (Lt.Cdr. A.F. Collett, DSC, RN). All aircraft, except the one lost, had returned to the carriers by 0930 hours after which both task forces retired to the west. The Japanese tried to attack the Allied task force with three torpedo bombers but these were shot down by Allied fighter aircraft at 1010 hours.

At Sabang the Japanese merchants Kunitsu Maru (2722 GRT, built 1937) and Haruno Maru (775 GRT, built 1927, former Dutch Kidoel) were sunk by the Allied aircraft while the Japanese minelayer Hatsutaka was damaged.
