1.Turchese (TC)9 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.

2.Turchese (TC)3 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.

3.Turchese (TC)9 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.

  12 Oct 1941094534° 00'N, 23° 50'EAt 0945 hours, an aircraft was sighted at 3,000 metres flying at an altitude of 500 metres. Millo did not have time to dive. The aircraft made a large circle and was identified as German. It flew away after 5 minutes.
  12 Oct 1941131533° 50'N, 24° 30'EAt 1315 hours, an aircraft, believed to be a Blenheim bomber, was sighted at a distance of 4,000 metres. It was flying at an altitude of 500 metres and dived from the sun to about 100 metres. As it flew over the submarine flashing a white light, the British cockades were clearly seen and Millo opened fire with her machine guns. The aircraft was believed to have been hit and did not try to attack. Millo submerged at 1322 hours.

This was probably Beaufort No.6504 of 39 Squadron piloted by Sergeant Harvey. It attacked a submarine in the afternoon.

  15 Oct 19411430
1426 or 1230 GMT (e)
34° 10'N, 22° 44'EAt 1430 hours, an enemy bomber was sighted at 1,000 metres. It came very quickly to the attack, dropping two depth charges which fell about 50 meters astern on the starboard side. They exploded a few seconds later. Millo did not have time to use her machine-guns and dived at 1431 hours.

This was Blenheim 'C' (Z9544) of 203 Squadron piloted by Pilot Officer Van der Water. It sighted a surfaced submarine on a course of 300 degrees at 10 knots (Millo was actually steering 284° at 12 knots). The bomber climbed to 3000 feet and made a diving attack, passing over the port quarter of the submarine at a height of 100 feet. One 250-lb GP bomb was dropped and observed to fall 10 feet astern of the submarine. The maneuver was repeated and a second bomb dropped on the now submerging submarine. A third attack was delivered in the same manner, this time with two bombs. The explosions raised a great mass of water just aft of the conning tower. The submarine disappeared and when the disturbance in the water had subsided bubbles were seen rising to the surface. It was considered that the submarine was destroyed. Millo had actually come out unscathed.

  9 Dec 1941100037° 18'N, 18° 59'EAt 1000 hours, an aircraft was seen at 5,000 metres flying at an altitude of 300 metres. It apparently maneuvered for an attack. Because the heavy seas prevented Millo from manning her machine guns efficiently, C.C. Miniero ordered the submarine to crash-dive, but no bombs were dropped.

Upon arrival, C.C. Miniero was told not to unload his cargo as the town was about to be evacuated and he communicated to MARICOSOM his intention to land his stores in Benghazi [ULTRA intercept].

(e) 38° 22'N, 15° 22'E
At 0530 hours, the submarine HMS Upholder (Lt. Cdr. M.D. Wanklyn, VC, DSO, RN) sighted what at first was believed to be a trawler, but later proved to be a two-gun submarine zig-zagging on course 260°-360° at 15 knots.

At 0538 hours, a single torpedo was fired at 1,000 yards. It was observed to hit just forward of the No. 1 gun. This was the last remaining torpedo and the first torpedo hit that Wanklyn actually watched.

This was Ammiraglio Saint Bon and she was hit amidship and this detonated her cargo and she sank very quickly. HMS Upholder picked up three survivors (an officer and two ratings). Eight officers and forty-nine ratings perished including C.C. Miniero.

The torpedo boat Centauro, two motorboats and an aircraft were sent to search for survivors, but none were found.
