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.

  30 Apr 19411727
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.

These were probably HMS Gurkha and HMS Legion, screening Force H and returning from operation HALBERD. They were shortly to sink Adua.

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).
