1Miniero, Gustavo9 Jun 19402002Cagliari21 Jun 19402005Cagliari1052Sailed to form a patrol line (S2) on the Cape Teulada meridian:

Axum - 15 miles south of the Cape.
Turchese - 35 miles south of the Cape.
Adua - 55 miles south of the Cape.
Aradam - 75 miles south of the Cape.

On 13th June, ordered to Gulf of Lyons and patrolled 15 miles east of Cape Creus until the evening of 19th June.
  21 Jun 19401015
(0) Italian Grid 0261 or northeast of Balearic Islands.
At 1015 hours, three small warships were sighted at a distance of 20,000 metres. Turchese closed to 14,000 metres and identified them as a large enemy force. She gave up the chase at 1148 hours.

The were probably the large destroyers of the French 8th DCT (Division de Contre-Torpilleurs), which at that time, were the fastest warships in the World.

2Miniero, Gustavo3 Jul 19401416Cagliari6 Jul 19401200Cagliari262Sailed with Aradam and patrolled between Bone and Cape de Fer in 37°54'N, 07°40'E, on a patrol line with Aradam, Axum and Alagi.

3Miniero, Gustavo9 Jul 19400057Cagliari12 Jul 19401105Cagliari354Patrolled between La Galite and Tunisia in 37°50'N, 09°40'E.
  12 Jul 1940032538° 24'N, 9° 19'EAt 0225 hours, an illuminated vessel was sighted by the First Officer who was Officer of the Watch. Turchese closed on her electric motors to avoid revealing her presence. It was thought that the vessel behaved strangely and was perhaps an enemy vessel on a minelaying mission.

At 0325 hours, one torpedo (533mm) was fired from a bow tube at a range of 500 metres. The phosphorescent wake appeared to hit amidships but it passed under the target.

At 0326 hours, a second torpedo (533mm) was fired from a bow tube at the same range with the same result. C.C. Gustavo Miniero intended to renew the action with a third torpedo and gunfire. However, at 0335 hours, the submarine had a violent shock with a metallic object, followed three minutes later by a second one more violent than the first. At 0410 hours, the action was broken off.

No British warships appear to have operated in the area at the time. The target was probably a neutral vessel.

  20 Mar 1941On this date, some sources claim that Turchese carried out an attack an enemy destroyer and was depth charged. This is an error and is not recorded in her report.

1939 (e)
At 1727 hours, Turchese was on a hydrophone watch, proceeding submerged, when suddenly she was shaken by two explosions believed to be from aircraft bombs. This was followed at 1842 hours, by eight more explosions and still more until 1940 hours. The submarine escaped by diving to 90-95 meters. Explosions were also heard the next day, but a distance. The diesel engines developed defects on 3rd May, perhaps due to the depth-charging, so the patrol was abandoned.

This was most likely an attack by the destroyers HMS Juno and HMS Jaguar who claimed the submarine probably sunk. HMS Juno was damaged by the premature explosion of a depth-charge and had five killed and eleven wounded.

  30 Sep 1941103936° 49'N, 0° 24'EAt 0503 hours, information was received that, at 0350 hours, the submarine Adua had sighted a squadron of eleven destroyers. However, it appeared this force would pass much farther north of Turchese.

At 1017 hours, smokes were sighted at a distance of 14,000 metres.

At 1039 hours, Turchese had closed to 6,000 metres and two cruisers of the ARETHUSA class and two destroyers could be made out.

At 1110 hours, the submarine was at a depth of 19 metres, when six explosions were heard near the submarine. Turchese was taken down to 40 metres. At 1339 hours, the hydrophone noises had ceased.

At 1958 hours on 2nd July, she was ordered to make an incursion on the 37°20'N parallel between 36°40'N and 07°40'E, then return to her original area. At 1255 hours on the 6th, she was ordered to move 10 miles East then to 37°50'N by dawn on the 7th. Her next move was from east to west from 08°10'E to Cape de Fer meridian (07°10'E) on 37°20'N [she was delayed because of defects] parallel and return to her area at dawn on the 8th.

At 0215 hours on 10th July , she received the order (0015/10) to execute the ZETA order and proceed to zone 96. At 1425 hours, she received a new order (1141/10) to immediately go to zone 172.

At 2127 hours, Turchese came under air attack from what was believed to be a Junker 88. The nearest bombs fell six meters off the port bow and exploded at a depth of ten meters. The submarine was seriously damaged and her port diesel engine was put out of action, but she reached Bone at 0002 hours on 13th September.

This was actually Hudson 'O' of 500 Squadron piloted by Pilot Officer G.M. Shires. The aircraft made two circuits, firing off the colors of the day on the second one. As there was no response, the submarine was attacked. The attack was carried out up moon from the starboard bow and a stick of four depth charges released, which straddled just forward of the conning tower. The submarine appeared to be diving stern first. Half an hour later, the aircraft received a signal from base ordering it to not attack unless the submarine was taking hostile action. What was believed to be the same submarine was sighted stern down and attacked and sunk by Bisley V/13 the next morning (this was probably Topazio).

Gustavo Miniero21 Jun 19401015(o) Italian Grid 0261 or northeast of Balearic Islands.At 1015 hours, three small warships were sighted at a distance of 20,000 metres. Turchese closed to 14,000 metres and identified them as a large enemy force. She gave up the chase at 1148 hours.

The were probably the large destroyers of the French 8th DCT (Division de Contre-Torpilleurs), which at that time, were the fastest warships in the World.
Gustavo Miniero22 Jun 19400831(o) West of Sardinia.At 0831 hours, the seaplane CANT Z.501 no. 3 of 146^ Squadriglia (based at St. Elmas) was seen to have alighted on the sea in some difficulty. Turchese took the crew of four on board and towed the aircraft to Cagliari. She was met by the auxiliary Meta who provided escort.
Gustavo Miniero12 Jul 1940032538.24 N, 09.19 E
At 0225 hours, an illuminated vessel was sighted by the First Officer who was Officer of the Watch. Turchese closed on her electric motors to avoid revealing her presence. It was thought that the vessel behaved strangely and was perhaps an enemy vessel on a minelaying mission.

At 0325 hours, one torpedo (533mm) was fired from a bow tube at a range of 500 metres. The phosphorescent wake appeared to hit amidships but it passed under the target.

At 0326 hours, a second torpedo (533mm) was fired from a bow tube at the same range with the same result. C.C. Gustavo Miniero intended to renew the action with a third torpedo and gunfire. However, at 0335 hours, the submarine had a violent shock with a metallic object, followed three minutes later by a second one more violent than the first. At 0410 hours, the action was broken off.

No British warships appear to have operated in the area at the time. The target was probably a neutral vessel.
Pier Vincenzo Di Domenico20 Mar 1941On this date, some sources claim that Turchese carried out an attack an enemy destroyer and was depth charged. This is an error and is not recorded in her report.
Pier Vincenzo Di Domenico30 Apr 19411727

(e) 32.59 N, 27.52 E
At 1727 hours, Turchese was on a hydrophone watch, proceeding submerged, when suddenly she was shaken by two explosions believed to be from aircraft bombs. This was followed at 1842 hours, by eight more explosions and still more until 1940 hours. The submarine escaped by diving to 90-95 meters. Explosions were also heard the next day, but a distance. The diesel engines developed defects on 3rd May, perhaps due to the depth-charging, so the patrol was abandoned.

This was most likely an attack by the destroyers HMS Juno and HMS Jaguar who claimed the submarine probably sunk. HMS Juno was damaged by the premature explosion of a depth-charge and had five killed and eleven wounded.
Pier Vincenzo Di Domenico5 Jun 19412043(o) 20 miles SW of Cape Krio (Crete).At 2043 hours, a submarine was sighted at a distance of 2,000 metres. As Turchese was submerging, the submarine was recognized as Italian. This was Smeraldo.
Pier Vincenzo Di Domenico30 Sep 1941103936.49 N, 00.24 E
(e) 37.10 N, 00.56 E
At 0503 hours, information was received that, at 0350 hours, the submarine Adua had sighted a squadron of eleven destroyers. However, it appeared this force would pass much farther north of Turchese.

At 1017 hours, smokes were sighted at a distance of 14,000 metres.

At 1039 hours, Turchese had closed to 6,000 metres and two cruisers of the ARETHUSA class and two destroyers could be made out.

At 1110 hours, the submarine was at a depth of 19 metres, when six explosions were heard near the submarine. Turchese was taken down to 40 metres. At 1339 hours, the hydrophone noises had ceased.

These were probably HMS Gurkha and HMS Legion, screening Force H and returning from operation HALBERD. They were shortly to sink Adua.
Pier Vincenzo Di Domenico2 Oct 1941065037.15 N, 03.12 E
At 0650 hours, a submarine was sighted at a distance of 2,000 metres. It was probably Italian. Visibility was poor and Turchese took avoiding action.
Giovanni Cunsolo13 Nov 19410600(o) 000° - Cape Blanc - 8 miles.At 0600 hours, an illuminated freighter was sighted. Turchese closed to 6,000 meters and observed the vessel proceeding to Bizerta. The submarine in the following days sighted only French or Italian vessels.
Pier Vincenzo Di Domenico19 Dec 1941094038.05 N, 07.47 E
At 0940 hours, a German U-boat (possibly U-74), sighted at a distance of 3,000 metres, made an unintelligible signal. Turchese proceeded on her course.
Pier Vincenzo Di Domenico21 Dec 1941012437.21 N, 06.22 E
At 0124 hours, a steamer believed to be French was sighted.

At 0124 hours, a steamer believed to be French was sighted.
Pier Vincenzo Di Domenico23 Dec 1941170537.21 N, 06.26 E
At 1445 hours, hydrophone noises were heard bearing 248°. The direction varied considerably. Turchese steered toward them.

At 1705 hours, two cruisers of the NEWCASTLE class and four destroyers of the JERVIS class were sighted at a distance of 12,000 metres, proceeding at 25 knots. The submarine could not close to less than 7,000 meters.

These were probably HMS Dido and the destroyers HMAS Nestor, HMS Zulu, HMS Gurkha, HMS Arrow and HMS Foxhound.
Pier Vincenzo Di Domenico11 Feb 19421500At 1500 hours, a submarine on a westerly course was sighted. It was believed to be Benedetto Brin.
Pier Vincenzo Di Domenico30 Mar 1942171237.25 N, 06.29 E
At 1712 hours, an aircraft was seen at a distance of 7,000 metres and Turchese dived. At the time, the submarine was proceeding to intercept an enemy cruiser reported SE of La Galite, at 2009 hours. It was believed that the cruiser had passed some ten miles away.

At 0300 hours, a large seaplane, believed to be a Catalina, was sighted a distance of 1,000 metres. Turchese crash-dived as five bombs exploded, but they caused only minor damages.

Indeed, this was Catalina 'J' (AJ.160) of 202 Squadron piloted by Flying Officer I.F. Edgar. The submarine had first been detected by radar at 8 miles and then sighted steering 075°. The attack was delivered from a height of 75 feet, as the submarine submerged. Seven depth charges were released (an 8th hung up) and a large oil slick was observed.
Pier Vincenzo Di Domenico8 Apr 19422120(o) Off Cape Bon.At 2120 hours, information was received that a cruiser and a destroyer had been sighted proceeding west. Turchese and Aradam were told to close the North African coast.

At 2127 hours, Turchese came under air attack from what was believed to be a Junker 88. The nearest bombs fell six meters off the port bow and exploded at a depth of ten meters. The submarine was seriously damaged and her port diesel engine was put out of action, but she reached Bone at 0002 hours on 13th September.

This was actually Hudson 'O' of 500 Squadron piloted by Pilot Officer G.M. Shires. The aircraft made two circuits, firing off the colors of the day on the second one. As there was no response, the submarine was attacked. The attack was carried out up moon from the starboard bow and a stick of four depth charges released, which straddled just forward of the conning tower. The submarine appeared to be diving stern first. Half an hour later, the aircraft received a signal from base ordering it to not attack unless the submarine was taking hostile action. What was believed to be the same submarine was sighted stern down and attacked and sunk by Bisley V/13 the next morning (this was probably Topazio).
