Career information

Jack Gethin Hopkins was born in Westbury On Trym, Bristol on 8 October 1908, son of Dr Francis and Marian Hopkins.

Jack joined the Royal Navy as a 17 year old Cadet in HMS Emperor of India on 15 January 1926. Over the ensuing four years his career advanced in various ships, shore establishments and training courses to Midshipman in 1926, Acting Sub Lt 1929 and Sub Lt 1930. During that year he undertook submarine training and joined HMS Regent when she was first commissioned and during his two years onboard received a watch keeper certificate and in 1932 was promoted to Lieutenant. Over the next seven pre-war years Jack’s service continued: in submarines interspaced with short term postings to General Service. After serving as 1st Lieutenant in four ships and submarines he successfully completed the Submarine Commanding Officer’s Qualifying Course (also known as ‘The Perisher’ due to its high rate of failure) following which he had his first command in submarine HMS L27.

On the outbreak of war Jack was in General Service onboard the battleship HMS Rodney, as a Divisional Officer & Officer of Quarters of a 16” Turret, and during this time he was promoted to Lieutenant Commander. He left her in May 1940 for the Commanding Officer’s Refresher Course and from 22 August 1940 for a year he was in command of the mine laying submarine HMS Porpoise serving in the Atlantic and English Channel. At the end of 1941 Jack took command of HMS Taku following her refit at Chatham and took her into the Mediterranean where she carried out five war patrols from Gibraltar, Alexandria, Haifa and Port Said.

During 1943 he commanded HMS Truant in the UK and then HMS Thorough from October to February 1945 – taking her from launch to the Far East as part of the 4th Submarine Flotilla's where in and around the Straits of Malacca and Sumatra she was depth charged and sank eight Japanese vessels. He was latterly Commanding Officer of the 'Lend Lease' Aircraft Carrier HMS Slinger in the Pacific, and post war returned her to the United States Navy in February 1946.

Jack, retired in 1953 after 32 years service, had married Florence Edwards in 1943 and died of cancer on 20 June 1967 aged just 58.

22 May 1942 (position 0.00, 0.00)
For the daily and attack positions of HMS Taku during her 15th war patrol see the map below.

25 May 1942
At 1425C/25, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received a signal from Capt. S.1 timed 1205C/25, ordering her to try to intercept an enemy barque on passage to Derna. The enemy vessel of about 200 tons had been reported at 2141C/24, in position 33°20'N, 22°01'E proceeding on course 160° at 3 knots.

This may have referred to the Italian schooner Annibale Bosco (227 GRT, built 1903) on passage from Benghazi to Derna.

Due to the bad weather conditions encountered on the 24th, HMS Taku is delayed and therefore unable to comply. (14)

27 May 1942
In a signal timed 2335C/27, Capt. S 1 informed HMS Taku (Lt.Cdr. J.G. Hopkins, RN) and HMS Turbulent (Cdr. J.W. Linton, DSC, RN) that a convoy made up of two transports and two destroyers had been sighted at 1901C/27 in position 38°46'N, 18°20'E proceeding on course 175° and 11 knots.

Later an amplifying report was sent in a signal timed 0241C/28 that at 0045C/28 the convoy had been in position 37°52'N, 18°40'E proceeding on course 160° at 12 knots. They were also informed that aircraft would attack the convoy during the night of 28/29 May.

This signal must have referred to the convoy made up of the transports Capo Arma (3172 GRT, built 1905) and Anna Maria Gualdi (3289 GRT, built 1908) escorted by the destroyers Antonio Pigafetta (S.O.) and Emanuelle Pessagno.

The Capo Arma and Antonio Pigafetta had departed Taranto around 0250B/27 while the other two ships had departed Brindisi around 0430B/27. These two sections of the convoy had joined company around 1040B/27. (15)

28 May 1942
In a signal timed 1911C/28, Capt. S 1 informed all submarines on patrol, which were HMS Proteus (Lt.Cdr. P.S. Francis, RN), HMS Taku (Lt.Cdr. J.G. Hopkins, RN) and HMS Turbulent (Cdr. J.W. Linton, DSC, RN and most likely also HMS Porpoise (Lt. L.W.A. Bennington, DSC, RN, which was on a storing trip from Alexandria to Malta) that at 1601C/28, three large merchant ships and four destroyers had been sighted in position 33°28'N, 20°00'E proceeding on course 330° and 13 knots.

This signal referred to the convoy made up of the transports / naval auxiliaries Città di Genova (5413 GRT, built 1930), Città di Napoli (5418 GRT, built 1929) and Città di Tunisi (5419 GRT, built 1929) escorted by the destroyers Ugolino Vivaldi (S.O.), Lanzerotto Malocello, Antoniotto Usodimare and Turbine. This convoy had departed Benghazi around 1040B/28 for Naples where it arrived around 1330A/28. (15)

30 May 1942
At 1730C/30, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received Capt. S 1's signal timed 1221C/30, which stated that an enemy convoy had been sighted at 1103C/30 in position 36°33'N, 18°24'E proceeding on course 200° at 15 knots. HMS Taku was in an excellent position to intercept this convoy.

The convoy in question was made up of the transports Rosolino Pilo (Italian, 8326 GRT, built 1942) and Gino Allegri (Italian, 6836 GRT, built 1941) escorted by the destroyers Nicoloso da Recco (S.O.) and Euro.

The Gino Allegri and Nicoloso da Recco had departed Brindisi around 1345B/29 while the other two ships had departed Taranto shortly before 1800B/29.

The two sections had joined around 0630B/30 about 100 nautical miles to the south-east of Punta Stilo.

The two sections split up later with the Rosolino Pilo escorted by the Nicoloso da Recco proceeding to Tripoli where they arrived around 1245B/31.

The Gino Allegri escorted by the Euro were to proceed to Benghazi but at 0542C/31 the Gino Allegri was torpedoed and sunk by HMS Proteus (Lt.Cdr. P.S. Francis, RN).

Following this first signal further amplifying reports were sent to the submarines on patrol. (16)

31 May 1942
HMS Taku (Lt.Cdr. J.G. Hopkins, RN) attacked a convoy and claims to have hit a merchant ship with a torpedo. Italian sources however makes no mention of this.

It is not known for sure which ships were sighted and attacked by Taku but most likely it was the transport Rosolino Pilo (Italian, 8326 GRT, built 1942) escorted by the destroyer Nicoloso da Recco en route to Tripoli where they arrived around 1245B/31.

At 1600C/31, HMS Taku received a signal from Capt. S 1, timed 1221C/31, ordering her to patrol in position 35°01'N, 20°44'E by 2301C/31. These orders were later cancelled in Capt. S 1's signal timed 1148C/1 but this signal was missed by HMS Taku which therefore lost a day of effective patrol. On receipt of the signal at 2230C/1, she set course to return to the Benghazi area.

0425C/31 - In position 33°34'N, 18°30'E sighted one destroyer and one large merchant ship bearing 230°, distance 5 nautical miles. The destroyer was zig-zagging widely across the bow of the merchant ship about 1 to 2 nautical miles ahead. Closed at full speed to attack.

0440C/31 - Dived and proceeded at full speed.

0443C/31 - Fired three torpedoes (four was intended but there was a problem with the firing valve of Nr. 6 torpedo tube) from 6000 yards (Taku was unable to get closed due to the destroyer).

0451C/31 - On loud explosion was heard. Taku went deep as the destroyer had turned back. Upon coming to periscope depth sighted sparks and a small amount of flame bearing 130, the approximate bearing of the ship when the torpedoes were fired. Nothing further was seen through the periscope but very shortly after seeing these spars there was a terrific explosion that sounded very close. Though nothing had been seen of the destroyer it was felt that this might have been a depth charge. Taku went deep for 15 minutes.

0550C/31 - Came to periscope depth. There was nothing in sight. Kept diving patrol towards Benghazi. (13)

2 Jun 1942
At 1830C/2, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received Capt. S 1's signal, timed 1611C/2, ordering her to patrol in position 35°01'N, 20°44'E by 0001C/4.

This was to be in position to intercept a convoy made up the transport Reginaldo Giuliani (Italian, 6837 GRT, built 1942) and the destroyer Freccia and the torpedo boats Pegaso and Partenope which were to proceed from Taranto to Benghazi. The passage of the convoy was known due to ULTRA, the interception and description of enemy radio traffic. (17)

3 Jun 1942 (position 0.00, 0.00)
At 0200C/3, in position 33°03'N, 19°46'E, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) sighted a northbound Spica-class torpedo boat bearing 270°. Speed of the enemy was 22 knots. HMS Taku dived for 30 minutes.

At 2050C/3, in position 34°27'N, 20°05'E, a ship, hull down, was seen bearing 340° at a range of 14 nautical miles. At 2110C/3, the ship had been identified as a hospital ship on course 120°, speed 16 knots. HMS Taku dived at 2120C/3 for 25 minutes to avoid being sighted. (13)

4 Jun 1942
At 0110C/4, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) arrived in the ordered patrol position.

At 0200C/4, operations in conjunction with aircraft started with the intention of homing the submarines onto the convoy.

At 0240C/4, a Wellington aircraft passed down the port side 600 yard away.

At 0245C/4, a flare was sighted bearing 090° but nothing was heard from the aircraft so altered course to 140° and increased to full speed.

At 0330C/4, a report from the aircraft was received (timed 0315C/4) that the convoy was well to the south and east.

At 0400C/4, Flares and AA fire was sighted bearing 110° to 115°.

At 0405C/4, a destroyer was seen bearing 110° at a range of 4 nautical miles. Enemy course was approximately 150°.

At 0415C/4, the destroyer was seen to alter course towards HMS Taku and appeared to be closing fast. HMS Taku therefore dived for about 10 minutes as no HE could be picked up. The destroyer was just visible in the moon going away at high speed. HMS Taku therefore proceeded at full speed on course 140°.

At 0445C/4, nothing was in sight and in view of the coming daylight, insufficient speed and now being well out of our patrol area decided to abandon the chase. Course was altered to the westward while charging the battery.

At 0550C/4, HMS Taku dived.

At 1515C/4, Capt. S 1's signal timed 1253C/4 was received. This stated that a damaged ship was reported in position 34°10'N, 21°01'E.

At 1601C/4, Capt. S 1's signal timed 1425C/4 was received giving more info on the damaged ship.

At 1615C/4, HMS Taku surfaced and proceeded at 13 knots to the south-east.

At 1710C/4, HMS Thorn (Lt.Cdr. R.G. Norfolk, DSO, RN) was sighted and spoke.

At 1725C/4, a Ghibli aircraft was sighted so dived and remained dived. proceeded on course 120°.

At 2030C/4, HMS Taku called HMS Thorn on SS/T as nothing had been seen and it was hoped that they may have sighted something of the enemy.

At 2115C/4, HMS Taku surfaced. Two destroyers were sighted bearing 220° at a range of 5 nautical miles. HMS Taku dived again.

At 2200C/4, HMS Taku surfaced but had to dive immediately as two destroyers were sighted only 300 yards on the port bow laying stopped. thy must have heard the submarine and a ineffectual depth charge attack then took place after which they made off. At 2210C/4 HE of the destroyers faded astern. HMS Taku surfaced again at 0045C/5 and retired to the west and then to the south but northing was seen of the damaged ship. (13)

5 Jun 1942 (position 0.00, 0.00)
At 2200C/5, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) set course for the Benghazi area. (13)

6 Jun 1942
HMS Taku (Lt.Cdr. J.G. Hopkins, RN) patrolled to the south-west of Benghazi.

At 2130C/6, a signal was received from Capt. S 1, timed 1925C/6, that two ships were at anchor to the west of Sirte. HMS Taku then proceeded to the south-west to attempt to intercept them between Sirte and El-Aguela. (13)

7 Jun 1942 (position 0.00, 0.00)
HMS Taku (Lt.Cdr. J.G. Hopkins, RN) patrolled near position 31°05'N, 18°13'E but nothing was seen.

On surfacing in the evening course was set to retire to the north as ordered by Capt. S 1. (13)

9 Jun 1942 (position 0.00, 0.00)
At 1415C/9, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received a signal from Capt. S 1 timed 1041C/9. The signal was corrupted and could not be deciphered.

At 2215C/9 a correct version of the above signal was received. It stated that an aircraft on passage had sighted a signalling light in position 34°52'N, 17°33'E. It was now too late to take action. (18)

10 Jun 1942 (position 0.00, 0.00)
At 0030C/10, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received Capt. S 1's signal timed 1851C/9 ordering her to take up her position for the upcoming operation Vigorous.

She subsequently patrolled in position 35°48'N, 20°30'E. (13)

11 Jun 1942
At 0110C/11, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received Capt. S 1's signal, timed 2137C/10, ordering HMS Taku and HMS Proteus (Lt.Cdr. P.S. Francis, RN) to take up new positions to the southward.

Whilst decoding this signal an aircraft report of two cruisers and nine destroyers was received. They were to the westward and on an east-north-easterly course. Lt.Cdr. Hopkins considered that the signal of Capt. S 1 was a purely routine nature and not operational and so he decided that if no action had been taken by Capt. S 1 by 0215C/11, that he would alter course to try to intercept the enemy units. The aircraft report showed that the enemy unit was making for Navarin.

At 0215C/11, HMS Taku set course for position 36°12'N, 20°25'E with the intention to intercept the enemy around 0500C/11.

At 0445C/11,HMS Taku arrived in position 36°12'N, 20°25'E.

At 0530C/11, HMS Taku dived for a day of submerged patrol.

By 0940C/11, nothing had been sighted and no information from Capt. S 1 had been received. HMS Taku surfaced and proceeded to comply with Capt. S 1's signal from 2137C/10.

At 1530C/11, HMS Taku commenced a diving patrol in position 35°10'N, 20°16'E. She also patrolled in this position on the 12th. (13)

13 Jun 1942
At 0544C/13, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) dived for a submerged patrol in 'Position X' (35°54'N, 20°07'E) which was her ordered position to provide cover during this part of 'Operation Vigorous'. On the 14th she was still patrolling in this position. (13)

14 Jun 1942 (position 0.00, 0.00)
At 2300C/14, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received Vice-Admiral Malta's signal that two enemy battleships and four destroyers had been sighted in position 39°50'N, 18°00'E and four cruiser and four destroyers had been sighted in position 39°36'N, 17°58'E. The enemy had been proceeding to the south-west at full speed at 1845C/14.

HMS Taku had however suffered an engine failure and both engines were out of action. The starboard engine was in action again soon after but she was unable to intercept the enemy due to insufficient speed. (13)

15 Jun 1942
At 0055C/15, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received Capt. S.1's signal timed 2356C/14, ordering the submarines on the (V-Z) patrol line to postpone taking up their new positions on the (V-Z one) patrol line until the 16th. The submarines were ordered to return to their positions on the original (V-Z) patrol line. HMS Taku complied.

At 0100C/15, HMS Taku dived for an hour as ordered in an earlier signal from Capt. S 1. She surfaced at 0210C/15, with both engines back in operation.

At 0325C/15, HMS Taku received a signal from the Vice-Admiral Malta which reported that an aircraft that at 0200 hours had sighted an enemy battleship, two cruisers and two destroyers in position 37°30'N, 19°35'E. Enemy course was 190° at 20 knot. HMS Taku altered course to the west and went to full speed to try to intercept.

At 0625C/15, an aircraft report was received of the enemy unit changing course to 240°. Obtaining contact was considered unlikely so HMS Taku dived and patrolled to the south-east. Later it became evident from the actual movements of this enemy unit that had HMS Taku continued on she most likely would have made contact with the enemy around 0800C/15.

At 1155C/15, HMS Taku and the other four submarines on the V-Z patrol line were ordered (Capt. S's signal timed 0825C/15) to proceed to their positions as originally ordered in their patrol orders for Operation Vigorous with D 4 as the 15th but with the convoy delayed 6 hours. HMS Taku and set course at speed for the new position.

At 1300C/15, HMS Taku received Capt. S 1's signal timed 1138C/15 cancelling the above signal. HMS Taku dived and proceeded to take up her position in the V2 - Z2 line.

At 1715C/15, Capt. S 1's signal timed 1315C/15, was received which ordered a new patrol line to be formed. Course was altered to comply and went to full speed.

At 1825C/15, a signal was received from Capt. S 1' which stated that at 1515C/15, the enemy fleet was in position 34°30'N, 21°33'E and was proceeding on course 330° at speeds between 20 and 25 knots. Both enemy battleships were reported to be damaged. Three enemy cruisers were reported to be 25 nautical miles to the southward of the battleships proceeding on course 320°. HMS Taku set course to try to intercept.

At 1914C/15, HMS Taku sighted a submarine which turned out to be HMS Proteus (Lt.Cdr. P.S. Francis, RN).

At 2200C/15, HMS Taku arrived in her intended patrol position from which she commenced patrolling to the south-south-east. (19)

16 Jun 1942
In the early hours of the 16th aircraft reports indicated that the enemy were now well to the northward.

At 0400C/16, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received a signal from Capt. S.1 timed 2321C/16, which gave new patrol positions for all submarines on patrol. HMS Taku was ordered to patrol in position 35°24'N, 21°33'E by damn on the 16th. Course was set to comply at full speed with the intention to remain on the surface until the position was reached.

At 0815C/16, HMS Taku dived 7 nautical miles short of her patrol position. She then patrolled in a south-easterly direction.

At 1830C/16, HMS Taku received Capt S 1's signal timed 1336C/16, ordering her to leave patrol and return to Alexandria. (19)

20 Jun 1942
Around 0930C/20, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) ended her 15th war patrol at Alexandria. (13)

30 Jun 1942
Around 1930C/30, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) departed from Alexandria for her 16th war patrol. She is to patrol along the coast of Cyrenaica, Libya.

(13)

2 Jul 1942 (position 0.00, 0.00)
At 2140C/2, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received a signal from the Senior Officer Submarines Alexandria ordering her to patrol in the vicinity of position 33°30'N, 22°30'E remaining south of 34'N, until dawn on the 4th. (20)

3 Jul 1942
At 2210C/3, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received Senior Officer, Submarines, Alexandria's (S.S.O.X.'s) signal, timed 1753C/3, which reported that an aircraft had sighted three merchant vessels and eight destroyers at 1600C/3, in position 37°25'N, 20°50'E. Enemy course was then 140° and speed 13 knots. HMS Taku was not in a position to intercept.

The convoy in question was made up of the transports Ankara (German, 4768 GRT, built 1937), Nino Bixio (Italian, 7137 GRT, built 1941) and Monviso (Italian, 5322 GRT, built 1941). They had a very strong escort made up of the Italian destroyers Giovanni da Verrazzano, Turbine, Euro and the Italian torpedo boats Antares, Castore, Polluce, Pegaso and San Martino. The convoy had departed Taranto around 1300B/2 and arrived at Benghazi around 1845B/4. The convoy had been attacked from the air on the 3rd.

At 2215C/3, HMS Taku received Senior Officer, Submarines, Alexandria's (S.S.O.X.'s) signal, timed 1928C/3, which ordered her to patrol off Apollonia starting at dawn the following day. HMS Taku set course to comply but it would be impossible to arrive in the position ordered by dawn though. It was expected she could arrive there early in the afternoon of the 4th. (20)

4 Jul 1942 (position 0.00, 0.00)
At 0440C/4, to the east-north-east of Derna, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) sighted a fully illuminated hospital ship bearing 280° at a range of 10 nautical miles. It was proceeding on course 140°. (13)

5 Jul 1942 (position 0.00, 0.00)
At 0030C/5, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) altered course to patrol off Derna.

At 0112C/5, HMS Taku sighted a fully illuminated hospital ship to the south-east. She was steering to the north-west but later altered towards and anchored off Derna.

The hospital ship got underway in the forenoon and disappeared to the westward. This may have been the small hospital ship Capri (Italian, 630 GRT, built 1930) which had departed Benghazi on the 4th and returned there on the 6th. (13)

6 Jul 1942
After having conducted a submerged patrol between Derna and Ras-el-Tin HMS Taku (Lt.Cdr. J.G. Hopkins, RN) surfaced at 2145C/6 and then set course to patrol her way back eastwards along the coast towards the direction of Alexandria. (13)

11 Jul 1942
Around 2100C/11, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) ended her 16th war patrol at Haifa. (13)

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

(21)

3 Aug 1942
In a signal timed 1201C/3, HMS Thorn (Lt.Cdr. R.G. Norfolk, DSO, RN) and HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received orders from the Senior Officer Submarines Alexandria.

HMS Thorn was to patrol on a line between positions 34°48'N, 22°04'E and 33°52'N, 21°52'E. She was to be in the former position at 1801C/4.

HMS Taku was to patrol on a line between positions 32°40'N, 23°15'E and 32°22'N, 23°36'E by dawn on the 5th.

An enemy convoy of large ships had been sighted off Otranto at 1035C/3 and these were probably bound for Benghazi and / or Tobruk.

The convoy sighted was the one made up of the transports Sestriere (Italian, 7992 GRT, built 1942) and Nino Bixio (Italian, 7137 GRT, built 1941). They were escorted by the destroyers Legionario (S.O.), Corsaro and the torpedo boats Calliope and Partenope. They had departed Brindisi around 0600B/3.

The were later joined by the transport Ankara (German, 4768 GRT, built 1937) and her escort, made up of the destroyers Freccia, Turbine, Grecale and Folgore. They had departed Taranto around 0030C/3.

The convoy split again around 1930B/4 with the Ankara and her escort group proceeding to Tobruk where they arrived around 1200B/5.

The two transports originating from Brindisi proceeded with their escort to Benghazi where they arrived around 1230B/5. The torpedo boat Pegaso had sailed from Benghazi as additional escort for the last leg of the voyage.

During the passage from Italy the convoy had been attacked from the air but no damage had been done.

-----------------------------------------------------------------------------------

Later an amplifying report was sent (Capt. S 10's signal timed 1930B/3) giving the position of this convoy at 1400B/3 as 39°27'N, 19°42'E on course 140° at 11 knots. (22)

4 Aug 1942
In a signal timed 1155C/4, the Senior Officer Submarines Alexandria cancelled his instructions for HMS Taku (Lt.Cdr. J.G. Hopkins, RN) given in his previous signal timed 1201C/3. HMS Taku was now ordered to patrol on a line between positions 32°25'N, 23°35'E and 32°14'N, 23°44'E by dawn on the 5th.

It also stated that aircraft would be attacking around 0200C/5 and would also drop flares.

This signal was also repeated to HMS Thorn (Lt.Cdr. R.G. Norfolk, DSO, RN).

In a signal timed 2345C/4, the Senior Officer Submarines Alexandria informed both submarines that an enemy convoy of one transport and four destroyers had been reported at 2305C/4 in position 33°36'N, 22°32'E proceeding on course 143° at 12 knots. The submarines were also informed that they were to act independently after 0901C/5. The convoy mentioned in this signal must have been the transport Ankara (German, 4768 GRT, built 1937) and her escorting destroyers Freccia, Turbine, Grecale and Folgore en route from Taranto to Tobruk [see also the event for 3 August 1942.] (22)

5 Aug 1942 (position 0.00, 0.00)
In a signal from the Senior Officer Submarines Alexandria, timed 1931C/5, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) is instructed that in case the enemy A/S activity in her current area is too great that she may proceed to position 33°32'N, 21°44'E remaining south-west until 0001C/7 or to position 32°51'N, 20°20'E remaining until 0601C/7 (22)

6 Aug 1942
In a signal from the Senior Officer Submarines Alexandria, timed 0931C/6, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) is instructed to postpone her move, as referred to in the signal timed 1931C/5, for 48 hours.

The signals timed 1931C/5 and 0931C/6 were later cancelled in a signal timed 0940C/8. (22)

7 Aug 1942
HMS Taku (Lt.Cdr. J.G. Hopkins, RN) intended to attack an eastbound schooner with gunfire of Ras-el-Tin. The attack is spoiled at the last possible moment by patrolling aircraft.

Later, what is thought to be, an eastbound MA/SB was sighted.

In a signal timed 0955C/7, the Senior Officer Submarines Alexandria informed HMS Proteus (Lt. R.L. Alexander, RN), HMS Traveller (Lt. M.B. St. John, RN) and HMS Taku (Lt.Cdr. J.G. Hopkins, RN) that one merchant vessel and two destroyers had been sighted at 0835C/7 in position 33°52'N, 23°25'E proceeding on a course of 350° at 11 knots and that a merchant vessel and one destroyer had been sighted at 0901C/7 in position 33°38'N, 21°36'E proceeding on a course of 050° at 9 knots.

The first sighting referred to a convoy made up of the transport Apuania (Italian, 7948 GRT, built 1942) escorted by the destroyer Folgore and the torpedo boat Castore. They had departed Tobruk around 1945B/7 for Brindisi via Patras.

The second sighting was the transport Istria (Italian, 5441 GRT, built 1921) escorted by the torpedo boat Pegaso. They had departed Benghazi 1700B/6.

0550C/7 - Dived for patrol of Ras-el-Tin.

0920C/7 - In position 32°21'N, 23°16'E sighted a two-masted schooner in ballast close inshore proceeding on course 270°. Decided to close and attack with the gun.

0945C/7 - When just about to surface in a favourable position, sighted two aircraft patrolling along the coast. Reluctantly abandoned the idea of sinking the schooner with gunfire.

1100C/7 - Sighted an MA/SB baring 140° at a range of 3 nautical miles on course 270°. (21)

8 Aug 1942 (position 0.00, 0.00)
In a signal timed 1915C/8, Capt. S 1, ordered HMS Taku (Lt.Cdr. J.G. Hopkins, RN) not to attack submarines unless identified as enemy, in an area enclosed by the north coast of Africa and latitude 35°00'N and longitude 19°00'E and 24°00'E.

Also HMS Taku was not to proceed within 20 miles of Ras el Tin from 0600C/10 until HMS Porpoise (Lt. L.W.A. Bennington, DSC, RN) had reported the completion of her minelaying mission. (22)

9 Aug 1942
In a signal timed 1920C/9, the Senior Officer Submarines Malta, informed HMS Taku (Lt.Cdr. J.G. Hopkins, RN) that aircraft had reported, at 1705C/9, a merchant vessel escorted by a destroyer in position 32°33'N, 20°09'E on a course of 060° at 8 knots. HMS Taku was ordered to intercept, at her discretion in the vicinity of position 33°38'N, 21°58'E.

HMS Taku received this signal at 2220C/9.

This must have referred to the transport Tagliamento (Italian, 5448 GRT, built 1922) which had departed Benghazi around 1300B/9 for Piraeus where she arrived around 0500B/12. She was escorted by the torpedo boat Procione.

By 0800C/10, HMS Taku had seen nothing and course was set to return to the Benghazi area. (22)

10 Aug 1942 (position 0.00, 0.00)
In a signal timed 1055C/10, the Senior Officer Submarines Alexandria, informed HMS Taku (Lt.Cdr. J.G. Hopkins, RN) and HMS Porpoise (Lt. L.W.A. Bennington, DSC, RN) that at 1005C/10 an aircraft had sighted an enemy submarine in position 34°02'N, 23°04'E proceeding on course 160° at 10 knots.

This must have referred to the Italian submarine Marcantonio Bragadino which was on passage from Taranto (departed 1017B/7) to Tobruk (arrived 1025B/11). (22)

10 Aug 1942
In a signal timed 1805C/10, the Senior Officer Submarines Alexandria, ordered HMS Turbulent (Cdr. J.W. Linton, DSC, RN), HMS Taku (Lt.Cdr. J.G. Hopkins, RN) and HMS Porpoise (Lt. L.W.A. Bennington, DSC, RN) to establish patrol in the following positions; HMS Turbulent in position 36°42'N, 21°26'E by dawn on the 13th. HMS Taku in position 34°40'N, 21°33'E by 1601C/13. HMS Porpoise, only if she had completed her minelaying mission, in position 34°56'N, 21°42'E by 1601C/13.

An important enemy convoy was expected to proceed from Italy to Benghazi.

This signal was repeated to the submarines concerned in the Senior Officer Submarines Alexandria signal timed 1601C/11.

In a signal timed 1804C/12, the Senior Officer Submarines Alexandria cancelled the instuctions given in his signal from 1805C/10. The sailing of the enemy convoy was delayed. (22)

13 Aug 1942
HMS Taku (Lt.Cdr. J.G. Hopkins, RN) attacked an enemy convoy. The attack fails as Taku is detected and the torpedoes could be avoided.

This convoy was made up of the transports Sibilla (Italian, 1077 GRT, built 1900) and Albachiara (Italian,1245 GRT, built 1904). They were escorted by the Italian torpedo boat Sagittario and submarine chaser Selve.

1230C/13 - In position 32°30'N, 20°08'E sighted what is thought to be a Crotone-class sloop escorting 2 medium seized motor vessels with three aircraft overhead. Started an attack.

1251C/13 - Fired three torpedoes at the rear ship. Sighted one of the aircraft coming straight toward. About 2 minutes after firing three bombs were dropped that were very close. All three navigation lights were broken. No hits were heard and it seems likely that the torpedoes could be avoided.

1320C/13 - Came to periscope depth, nothing in sight. Resumed dived patrol to the Westward. (21)

13 Aug 1942 (position 0.00, 0.00)
In a signal timed 1145C/13, Capt. S 1 informed HMS Taku (Lt.Cdr. J.G. Hopkins, RN) to stay 5 nautical miles in all directions from position 32°42'N, 23°06'E due to British moored mines having been laid in that position by HMS Porpoise (Lt. L.W.A. Bennington, DSC, RN).

HMS Taku was now allowed to enter this general area as the minelay by HMS Porpoise. [See also the signal timed 1915C/8.] (22)

13 Aug 1942 (position 0.00, 0.00)
In a signal timed 1240C/13, the Senior Officer Submarines Alexandria, informed HMS Turbulent (Cdr. J.W. Linton, DSC, RN), HMS Taku (Lt.Cdr. J.G. Hopkins, RN) and HMS Porpoise (Lt. L.W.A. Bennington, DSC, RN) that one small transport (less then 2000 tons) had been sighted at 1208C/13 in position 32°52'N, (longitude indecipherable) proceeding on course 120° at 4 knots and also that at 0930C/13, two transports and two destroyers had been sighted in position 33°21'N, 21°12'E on course 045° at 8 knots.

[We have been unable to identify the ships reported.] (22)

14 Aug 1942 (position 0.00, 0.00)
In a signal timed 1713C/14, Capt. S 1, ordered HMS Taku (Lt.Cdr. J.G. Hopkins, RN) to leave patrol P.M./16 through positions 33°01'N, 24°21'E and then direct to Beirut. (22)

14 Aug 1942
In a signal timed 1105C/15, the Senior Officer Submarines Alexandria informed HMS Turbulent (Cdr. J.W. Linton, DSC, RN), HMS Taku (Lt.Cdr. J.G. Hopkins, RN) and HMS Porpoise (Lt. L.W.A. Bennington, DSC, RN) that an enemy convoy made up of one transport and two destroyers had been sighted at 0810C/14 in position 34°20'N, 23°19'E on course 345° at 12 knots.

[We have been unable to identify the ships reported.]

-----------------------------------------------------------------------------------

In a signal timed 1141C/15, the Senior Officer Submarines Alexandria ordered these submarines to establish patrol in the following positions; HMS Turbulent in position 36°52'N, 21°27'E by 0001C/15. HMS Taku in position 33°23'N, 20°56'E by 01001C/15 and HMS Porpoise in position 34°39'N, 21°36'E by 0001C/15 as a large enemy convoy was expected to proceed from Italy to Benghazi.

-----------------------------------------------------------------------------------

In a signal timed 1232C/15, the Senior Officer Submarines Alexandria informed these submarines that an enemy convoy of two transports and four destroyers had been sighted at 1145C/14 in position 39°25'N, 18°30'E proceeding on course 120° at 15 knots. Also a convoy made up of one transport and two destroyers had been sighted at 1130C/14 in position 36°14'N, 23°36'E on course 200° at 15 knots.

The convoy reported at 1145C/14 was made up of the transport Ravello (Italian, 6142 GRT, built 1941) escorted by the Italian destroyer Nicoloso da Recco and the torpedo boat Polluce who had left Taranto at 0335B/14 and the transport Lerici (Italian, 6070 GRT, built 1941) escorted by the torpedo boats Calliope and Castore who sailed from Brindisi at 0515B/14. Both convoys merged at 1030B/14. They were bound for Benghazi.

The convoy reported at 1130C/14 was made up of the transport Foscolo (Italian, 4538 GRT, built 1942) escorted by the Italian destroyer Saetta and the Italian torpedo boats Orione and Sirio. They had sailed from Piraeus at 0215B/14 (except Saetta who joined from Suda at 0830B/14). They were also bound for Benghazi.

In an amplifying signal timed 1415C/14, the Senior Officer Submarines Alexandria informed these submarines that the destination of the first convoy was Benghazi. Aircraft would attack this convoy between 0200C/15 and 0400C/15 and would also drop flares. The destination of the second convoy most probably also Benghazi but it was also possible it's destination was Tobruk. Aircraft would search for and reports this convoy between 0100C/15 and 0300C/15 and would also drop flares.

In an amplifying signal timed 1910C/14, the Senior Officer Submarines Alexandria informed HMS Taku and HMS Porpoise that the second convoy [the one sighted at 1130C/14] was at 1630C/14 in position 35°14'N, 23°13'E proceeding on course 225° at 15 knots. (22)

15 Aug 1942 (position 33.16, 21.16)
HMS Taku (Lt.Cdr. J.G. Hopkins, RN) attacked the transport Menes (German, 5609 GRT, built 1926) with four torpedoes about 90 nautical miles north-east of Benghazi, Libya in position 33°16'N, 21°16'E. All torpedoes however fired missed their target.

Menes had departed Benghazi around 1900B/14 escorted by the Italian torpedo boats Pallade and Sagittario. Menes arrived at Piraeus around 0930C/17 after having made a stop at Suda Bay on the 16th.Sagittario remained at Suda Bay while the destroyer Giovanni da Verrazzano joined for the remainder of the trip to Piraeus.

0729C/15 - Sighted one merchant vessel, about 5000 tons, escorted by two Spica-class torpedo boats (one ahead and one astern of the merchant) and one aircraft overhead bearing 185°, range 7 nautical miles. Went to 70 feet and closed at speed for 15 minutes.

0807C/15 - Fired the first torpedo of a salvo of four. Immediately after firing this first torpedo the target changed course. Hold fire.

0810C/15 - Fired three torpedoes. No hits. Taku went deep.

0833C/15 - Depth charging commenced in patterns of six. All were astern and not close.

0915C/15 - The last pattern of depth charges was dropped.

0930C/15 - No HE was heard, came to periscope depth. Nothing in sight. Resumed dived patrol eastwards. (21)

15 Aug 1942
In a signal timed 1105C/15, the Senior Officer Submarines Alexandria informed HMS Taku (Lt.Cdr. J.G. Hopkins, RN) and HMS Porpoise (Lt. L.W.A. Bennington, DSC, RN) that the convoy reported at 1145C/14 in his signal timed 1232C/14 was in position 36°22'N, 21°39'E at 0905C/15.

Later an amplifying signal was sent timed 1515C/15 which stated that the convoy at 1335C/15 had been in position 35°44'N, 22°14'E proceeding on course 210° at 13 knots. (22)

15 Aug 1942 (position 0.00, 0.00)
In a signal timed 1951C/15, the Senior Officer Submarines Alexandria informed HMS Taku (Lt.Cdr. J.G. Hopkins, RN) that the were no aircraft available to cooperate with her the coming night. HMS Taku was allowed to proceed to position 32°47'N, 20°17'E at her own discretion.

Lt.Cdr. Hopkins decided to remain on patrol in the present area. (23)

16 Aug 1942
At 0215C/16, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) picked up HE bearing 090°. HMS Taku commenced to close at speed.

At 0223C/16, the HE was heard crossing across the bow.

At 0230C/16, a destroyer was seen bearing 120° at a range of approximately 3000 yards. HMS Taku altered course and increased to full speed for three minutes to evade this destroyer.

Subsequently HE of two destroyers was picked up and the Commanding Officer also sighted the second destroyer. No HE of a merchant vessel could be heard though.

HE continued to draw right at speed. Lt.Cdr. Hopkins decided not to attack the destroyers and contact was soon lost. HMS Taku then resumed patrol.

The destroyers were most likely the Bersagliere and Mitragliere which were searching the area for survivors of the transport Lerici (6070 GRT, built 1941)

At 2100C/16, HMS Taku left patrol to proceed to Beirut. (21)

21 Aug 1942
Shortly before arriving at Beirut, where she ended her 17th war patrol, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) is depth charged in error by a British Wellington aircraft.

HMS Taku arrived at Beirut around 0800C/21.

0510C/21 - In position 33°59'N, 34°48'E sighted a Wellington aircraft. The light by then was good and the aircraft flew close on both sides until 0555C/21 when it approached from the starboard quarter and released two depth charges which dropped 15 feet and 20 yards on the port beam and bow respectively. The first narrowly missed the periscope standards. None the less Taku suffered no damage. (21)

2 Sep 1942
Around 1915C/2, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) departed from Beirut for Port Said. (24)

4 Sep 1942
Around 0740C/4, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) arrived at Port Said from Beirut. (24)

5 Sep 1942
HMS Taku (Lt.Cdr. J.G. Hopkins, RN) is docked in the floating dock at Port Said. (24)

7 Sep 1942
HMS Taku (Lt.Cdr. J.G. Hopkins, RN) is undocked. (24)

9 Sep 1942
Around 1900C/9, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) departed from Port Said for her 18th war patrol. She is to patrol along the coast of Cyrenaica, Libya.

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

(21)

14 Sep 1942
HMS Taku (Lt.Cdr. J.G. Hopkins, RN) tries to land a party of four by folbots off Tobruk for a beach reconnaissance for an upcoming operation [Operation Agreement]. The attempt is aborted due to the unfavourable weather conditions.

0520C/13 - Dived 15 nautical miles north of Tobruk and proceeded inshore to carry out a periscope reconnaissance of Mersa Mreira.

1400C/13 - Established the identity and location of the above inlet. The folbotists were all given the opportunity to view the inlet from the seaward.

1505C/13 - A burst of machine gun fire was seen along the port side from an unknown source. No aircraft was in sight at this time.

1930C/13 - A final fix was taken before HMS Taku ran out to seaward.

2300C/13 - Surfaced 10.5 nautical miles to the north of Tobruk.

0010C/14 - Commenced to run in towards the inlet.

0115C/14 to 0140C/14 - Although the weather conditions appeared favourable all attempts to launch the folbots and subsequently rubber boat were aborted by an occasional cross swell which swept the casing despite the submarine being at nearly full buoyancy. Nine men were swept into the sea including all the landing party. They were recovered in due course but slightly fatigued. The landing attempt had to be aborted.

0145C/14, HMS Taku withdrew to the northwest with despatch. A signal, timed 0134C/15 was sent that the landing had to be aborted. (21)

14 Sep 1942 (position 0.00, 0.00)
At 1810C/14, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) is informed by Capt. S 1, in his signal timed 1635C/14, that she now had freedom of action in the Tobruk general area. (21)

15 Sep 1942
HMS Taku (Lt.Cdr. J.G. Hopkins, RN) acted on an aircraft report that at 0035C/15 a large transport and five small craft had been sighted in position 33°40'N, 22°51'E on course 180° at a speed of 8 knots. Lt.Cdr. Hopkins hoped to intercept these ships around 0345C/15.

The ships sighted were part of a convoy made up of the tanker Alberto Fassio (Italian, 2289 GRT, built 1914) and the Italian motorized lighters MZ 721, MZ 729, MZ 730, MZ 763 and MZ 764 [source is the report of the Cassiopea.]. They were escorted by the German destroyer Hermes (former Greek Vasilefs Georgios) and the Italian torpedo boat Cassiopea. The convoy arrived at Tobruk around 1215B/15 except MZ 764 which had proceeded to Derna.

Flares were seen throughout most of the night but the convoy was never seen.

At 0721C/15, north-north-east of Derna, in position 32°51'N, 22°42'E, HMS Taku sighted a transport of about 1500 tons escorted by what is thought to be a Generali-class torpedo boat. Enemy was sighted bearing 090° at a range of about 5 nautical miles. HMS Taku started an attack but it had to be broken off at 0805C/15 as no favourable attack position could be obtained as the enemy was close inshore proceeding on a course of 255°. HMS Taku then resumed her patrol eastwards.

The ships sighted were most likely the small transport Ostia (German, 359 GRT, built 1905, former Spanish Nere-a-Metza) and her escort, the Italian torpedo boat Generale Antonio Cascino.

At 0830C/15, in position 32°48'N, 22°43'E, a landing barge was seen escorted by a motor torpedo boat or motor minesweeper. They were close inshore bound for Derna. The landing barge was most likely the Italian MZ 764. [We have not been able to identify the escort.]

At 1030C/15, in position 32°50'N, 22°42'E HMS Taku sighted a large merchant vessel to the west of Derna. She was not escorted.HMS Taku commenced an attack. At 1110C/15, the ship was on a course to enter Derna and it was thought to be a hospital ship. She was seen to anchor in Derna roads at 1130C/15. HMS Taku closed to investigate and at 1145C/15 the ship was definitely identified as a hospital ship. The ships sighted was most likely the small hospital ship Aquileia (Italian, 256 GRT, built 1935).

HMS Taku now resumed patrol.

At 1830C/15, HMS Taku received Capt. S 1's signal timed 1740C/15, which stated that one southbound transport escorted by two destroyers had been sighted and that flares would be dropped during the night.[No further details available.]

At 2115C/15, HMS Taku surfaced and set course to the north-west to make contact with the enemy convoy between 0300C/16 and 0400C/16. [We have been unable to identify this convoy.]

During the night HMS Taku sighted flares but no convoy was seen. (21)

16 Sep 1942
At 1515C/16, in position 32°23'N, 20°47'E, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) sighted, what are thought to be an Confienza-class and an Orsa-class torpedo boat, bearing 290° at a range of 5 nautical miles. They were on course 145° obviously bound for Tobruk. Two aircraft were patrolling overhead. It was thought that the rear torpedo boat was towing a long low barge.

The ships sighted were the Italian torpedo boat Castelfidardo and the Italian destroyer Saetta which was towing the fuel barge (former submarine) Domenico Millelire. They had left Navarino at 0520B/15 and arrived at Tobruk at 1000B/17.

At 2200C/16, HMS Taku, which had surfaced at 2115C/16, had to dive for two destroyers proceeding to the north-west at high speed. [We have so far been unable to identify these ships.] (21)

17 Sep 1942 (position 0.00, 0.00)
In a signal timed 2116B/17, Capt. S 10, informed HMS Taku (Lt.Cdr. J.G. Hopkins, RN) that at 2143C/17, an aircraft had sighted a convoy made up of three transports and two destroyers in position 33°15'N, 23°39'E on course 170° at 6 knots.

[For the composition of this convoy see the event for 18 September 1942.] (25)

18 Sep 1942
HMS Taku (Lt.Cdr. J.G. Hopkins, RN) attacked an enemy convoy in position 32°29'N, 23°34'E. Four torpedoes were fired and a sinking is claimed.

The convoy attacked was made up of the transports Corso Fougier (Italian, 1359 GRT, built 1906), Nerucci (Italian, 1180 GRT, built 1892) and Dora (German, 795 GRT, built 1898). They were escorted by the Italian torpedo boats Sirio and Lupo. They had sailed from Suda Bay around 1455B/16 and arrived at Tobruk around 1015B/18.

0303C/18 - Sighted a darkened ship bearing 036°, distance 3 nautical miles. Identified as a destroyer.

0308C/18 - Sighted two merchant ships bearing 030°, distance 3 nautical miles. Closed at speed to attack.

0320C/18 - In position 32°29'N, 23°34'E fired four torpedoes at the leading ship. Dived.

0327C/18 - Heard a loud explosion.

0336C/18 - Heard another loud and prolonged explosion.

0345C/18 - Periscope depth, nothing in sight.

0415C/18 - Surfaced. Sighted a dark object in the vicinity of the attacking position and closed on main motors. The object was identified as a destroyer that was thought to be picking up survivors. Thought one ship to be hit and sunk.

0430C/18 - Retired to the North. (21)

19 Sep 1942 (position 0.00, 0.00)
In a signal timed 0858C/19, Capt. S 1 ordered HMS Taku (Lt.Cdr. J.G. Hopkins, RN) to patrol off Benghazi.This signal was received at 1048C/19 and HMS Taku altered course to the north-west to comply. [No further details available on this signal]

In a signal timed 1101B/19, Capt. S 10 informed HMS Taku (Lt.Cdr. J.G. Hopkins, RN) that an enemy convoy of two transports and seven destroyers had been sighted in position 38°28'N, 20°15'E on course 175°, speed 10 to 12 knots. [For the composition of this convoy see the event for 20 September 1942.]

This signal referred to a convoy made up of (26)

19 Sep 1942 (position 0.00, 0.00)
In a signal timed 0858C/19, Capt. S 1 ordered HMS Taku (Lt.Cdr. J.G. Hopkins, RN) to patrol off Benghazi.This signal was received at 1048C/19 and HMS Taku altered course to the north-west to comply. [No further details available on this signal.]

In a signal timed 1101B/19, Capt. S 10 informed HMS Taku (Lt.Cdr. J.G. Hopkins, RN) that an enemy convoy of two transports and seven destroyers had been sighted in position 38°28'N, 20°15'E on course 175°, speed 10 to 12 knots. [For the composition of this convoy see the event for 20 September 1942.]

At 1705C/19, Capt. S 1, ordered HMS Taku to proceed to a new patrol position with all despatch. The distance she had to cover was 115 nautical miles but as many aircraft had been sighted throughout the day it was not considered wise to surface during daylight hours. At 1930C/19, HMS Taku surfaced and set course for the position ordered at 13.5 knots. [No further details available on this signal.]

At 2230C/19, HMS Taku received Capt. S 1's signal timed 2055C/19, giving more details of the expected southbound convoy and an interception position. [No further details available on this signal.] (26)

20 Sep 1942 (position 33.30, 21.10)
HMS Taku (Lt.Cdr. J.G. Hopkins, RN) attacked an enemy convoy in position 33°30'N, 21°10'E. Three torpedoes were fired without result.

This convoy was made up of the transports Apuania (Italian, 7948 GRT, built 1942) and Monginevro (Italian, 5324 GRT, built 1940) escorted by the Italian destroyers Freccia (S.O.), Antonio Da Noli, Nicolò Zeno and the torpedo boats Calliope, Ciclone, Centaure and Pallade. Apuania reported missed by one torpedo and Monginevro missed by two.

The Monginevro escorted by the Antonio Da Noli, Ciclone, Centaure and Pallade had departed Taranto around 1850B/18. The Apuania escorted by the Freccia, Nicolò Zeno and Calliope had departed Brindinsi around 1900B/18.

The two sections of the convoy merged at 0700B/19. During the night of 19/20 September 1942 the convoy was attacked by aircraft. The convoy arrived at Benghazi at 1640B/20.

0900C/20 - Sighted a convoy made up of two transports and two destroyers with a whole lot of aircraft overhead. It's likely there were more ships but the periscope could only be put up for very brief moments. Commenced attack.

0925C/20 - In position 33°30'N, 21°10'E fired three torpedoes at the port wing ship from 1500 yards. Went deep after firing as one of the destroyers was very close.

0930C/20 - Heard one explosion, most likely a depth charge.

0932C/20 - Heard two explosions, most likely depth charges.

1025C/20 - Came to periscope depth, nothing in sight. (27)

21 Sep 1942
During the day, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) conducted a submerged patrol near position 33°30'N, 21°30'E. She had been given freedom of action in her present patrol area in a signal from Capt. S 1 timed 0205C/21. (21)

22 Sep 1942
During the day, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) conducted a submerged patrol to the north-west of Tolmeita, Libya near position 32°53'N, 20°43'E.

The Vice-Admiral Malta informed HMS Taku in a signal timed 1039B/22 that an enemy convoy made up of one transport and three destroyers had been sighted at 0845C/22 in position 39°44'N, 18°38'E, course 110° at a speed of 8 knots. [We have been unable to identify this convoy.] (21)

23 Sep 1942
During the day, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) conducted a submerged patrol well to the north of Tolmeita, Libya near position 33°24'N, 20°50'E. (21)

24 Sep 1942
At 0030C/24, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) received an aircraft report of 1423C/23 of a slow southbound convoy. Altered course to intercept it. This reported stated that one transport and two destroyers in position 35°17'N, 23°23'E on course 180° at 5 knots.

This aircraft sighting must have referred to the tanker Rondine (6468 GRT, built 1924) escorted by the destroyer Hermes and the Italian torpedo boat Orsa. They had departed Suda Bay around 0230B/23 and arrived at Tobruk around 1315B/24. The convoy thus must have been faster then the aircraft had reported.

At 0715C/24, HMS Taku dived in position 33°28'N, 22°37'E. Interception now seems unlikely. The weather, low cloud and sun prevented HMS Taku from running on the surface longer.

At 1005C/24, HMS Taku received Capt. S 1's signal timed 0818C/24, ordering a new patrol position for the 25th. [No further details available on this signal, the new position appeared to be to the north-north-east of her current patrol position.] (28)

25 Sep 1942 (position 0.00, 0.00)
At 0030C/25, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) altered course to 345° to proceed toward the ordered patrol position.

At 0650C/25, HMS Taku dived in position 34°12'N, 22°40'E and continued to proceed to the north-west.

At 1710C/25, HMS Taku received Capt. S 1's signal timed 1443C/25, which gave the details of a southbound convoy and subsequent movements. [No further details available on this signal.]

The convoy referred to must have been the one made up of the transports Anna Maria Gualdi (Italian, 3289 GRT, built 1908) and Menes (German, 5609 GRT, built 1926). They were escorted by the Italian destroyer Nicoloso da Recco and the Italian torpedo boats Castore, Lupo and Sirio. This convoy had departed Piraeus around 2300B/24. This convoy actually was to be joined around 1500B/25 by the tanker Proserpina (Italian, 4870 GRT, built 1926) and the torpedo boats Libra and Lira which had departed Suda Bay around 0830B/25. The convoy was then expected to arrive at Tobruk around 1600B/26 but in the end they arrived two hours early. The torpedo boat Sirio however had developed condenser (steam tube) trouble around 1045B/25 north-north-east of Anti-Kithera in position 36°08'N, 23°23'E and was detached to Suda Bay to effect repairs. She arrived at Suda Bay around 1900B/25.

A 1715C/25, in position 34°30'N, 22°47'E, HMS Taku sighted a periscope right astern. at 1640C/25, HE of a submarine had already been picked up. This was most likely HMS Turbulent (Cdr. J.W. Linton, DSO, DSC, RN) but she reported nothing around this time. (29)

26 Sep 1942 (position 0.00, 0.00)
At 0222C/26, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) sighted very distant flares bearing 137°. HMS Taku increased speed to 14 knots and altered course to 157°.

At 0230C/26, an aircraft report was received that at 0200C/26 the convoy had been 50 nautical miles to the south-east.

At 0900C/26, HMS Taku dived, having remained on the surface to close Tobruk until it was considered unsafe to remain on the surface any longer.

At 1345C/26, in position 33°01'N, 23°26'E a small dark object was seen bearing 250° which disappeared after a few minutes the bearing having altered 30 degrees in four minutes. This was thought to be HMS Turbulent (Cdr. J.W. Linton, DSO, DSC, RN) which may have surfaced briefly to take a sight.

At 2015C/26, HMS Taku surfaced and continued toward Tobruk while charging.

At 2210C/26, HMS Taku received Capt. S 1's signal timed 1709C/26 ordering her to leave patrol P.M. on the 27th. (28)

27 Sep 1942
At 0003C/27, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) sighted flares, AA fire and a smoke screen bearing 215°. HMS Taku altered course toward to close.

At 0017C/27, two heavy explosions were heard ahead.

At 0027C/27, a destroyer was seen close ahead beam on and apparently stopped. Two minutes later the destroyer altered course towards so HMS Taku dived. It appeared this destroyer was making moke. It was thought that a convoy was proceeding northwards but nothing could be seen. It was thought that a ship may have been hit at 0017 by either aircraft or HMS Turbulent (Cdr. J.W. Linton, DSO, DSC, RN). By 0042C/27, the destroyer had been lost from sight so HMS Taku surfaced.

At 0045C/27, a small vessel was sighted bearing 350°. HMS Taku immediately dived again as it was thought to be a motor torpedo boat [or motor minesweeper]. Avoiding action was taken and course was altered to the east-south-east. It looked like this vessel suspected the submarines presence as she remained near HMS Taku until 0250C/27.

At 0315C/27, HMS Taku surfaced and withdrew to the east-north-east.

At 0500C/27, HMS Taku altered course to 163° to close Tobruk.

At 0545C/27, in position 32°34'N, 23°30'E, a periscope was seen on the port beam. HMS Taku altered course to ram but nothing further was seen and no HE was picked up. If this was HMS Turbulent then she had ample opportunity to study Taku's silhouette. If it was an enemy submarine she had just missed a ' golden opportunity '. HMS Turbulent was surfaced at this time but most likely it was the Italian submarine Santorre di Santarosa which arrived at Tobruk from Taranto at 0801B/27.

At 0630C/27, HMS Taku dived and closed the coast.

At 1900C/27, HMS Taku was still about 10 nautical miles from the coast. Nothing further had been sighted all day. She now started to proceed to the north.

At 2015C/27, HMS Taku surfaced and continued to proceed to the north.

At 2100C/27, HMS Taku left patrol to proceed to Beirut as ordered in Capt. S 1's signal timed 1709C/26. [No further details available on this signal.] (30)

1 Oct 1942
Around 0630C/1, HMS Taku (Lt.Cdr. J.G. Hopkins, RN) ended her 18th war patrol at Beirut. (21)

Submarine HMS Truant (N 68)
