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.

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.

(All times are zone -3)
0425 hours - 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.

0440 hours - Dived and proceeded at full speed.

0443 hours - 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).

0451 hours - 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.

0550 hours - Came to periscope depth. There was nothing in sight. Kept diving patrol towards Benghazi.

(It is not known for sure which ships were sighted and attacked by Taku but most likely it was the brand-new Italian transport Rosolino Pilo (8326 GR, built 1942) escorted by the destroyer Nicoloso da Recco).

1251 hours - Fired three torpedoed 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 torpedoed could be avoided.
