Meneghini, Vittorio1 Jun 19401058La Spezia3 Jun 19402131TarantoPassage La Spezia-Taranto.

1Meneghini, Vittorio5 Jun 19400245Taranto20 Jun 19402125Crotone2118Laid 40 mines off Alexandria, from 31°17.15'N, 29°32°55'E to 31°18.45'N, 29°33.45'E . Meneghini (born 11th June 1900) was awarded the Medaglia d'argento.
  8 Jun 1940210033° 20'N, 22° 40'EAt 2100 hours, an escorted steamer was sighted. The escort vessel turned toward the submarine as if she attempted to ram. Pietro Micca dived immediately and the vessel passed just above her.
  12 Jun 19400330-035631° 17'N, 29° 32'EBetween 0330 and 0356 hours, a minefield of 40 mines was laid from 31°17.15' N, 29°32°55' E to 31°18.45' N, 29°33.45' E. The initial mine was laid at a depth of 299 metres.

At 1940 hours on the same day, the destroyer HMAS Stuart sighted a mine 17 miles from Ras El Tin (Alexandria) lighthouse and detected more with her ASDIC. In all, 11 mines laid in 130 fathoms were destroyed the same day. These mines were cleared by the minesweepers HMS Abingdon and HMS Bagshot of the 2nd Minesweeping Flotilla on the next day.

Mines were located in:

31°20' N, 29°34.5' E
31°17.5' N, 29°28' E
31°24.5' N, 29°36.5' E
31°32.5' N, 29°46.5' E.

It is possible that a mine from this field survived the minesweeping and damaged the destroyer HMS Janus at 1724 hours on 4th June 1942 in 31°15.5' N, 29°44' E. The mine detonated in her wake and the ship required three weeks repairs.

The consequence of this minefield was that British naval forces, and in particular submarines, were instructed to keep outside the 200-fathom line from enemy coast.
  12 Jun 1940073031° 30'N, 29° 40'EBetween 0730 and 1100 hours, depth charges were heard in the distance and it was believed that Micca was the object of a hunt.

(e) 31° 33'N, 29° 50'E
(0) About 25 miles NW of Alexandria.
Distant explosions were heard in groups of four and were probably those from the destroyers HMAS Voyager and HMS Decoy which were hunting a U-boat contact (it was bogus).

3Ginocchio, Alberto4 Aug 19401700Taranto21 Aug 19401325Taranto2123Laid 40 mines from 31°22'N, 29°27'E, northwest of Alexandria, then patrolled in area between 32°00'N and 32°40'N and 28°20'E and 29°20'E.
  12 Aug 1940002531° 22'N, 29° 42'E
(0) Approximately.
Between 0025 and 0055 hours, Micca laid 40 mines on a line 3.6 km in length eastward from 31°22' N, 29°42' E at a depth of 322 fathoms.

Eight mines were swept on 12th August in 320° - Ras-El-Tin (Alexandria) -14 miles, seven on 13th August and four on 14th August. Admiral Cunningham reported that a mine was recovered on 13th August 1940, which showed a sinker with 51 fathoms of mooring wire and another 207 fathoms when she was laid. Another 26 mines were destroyed (two were floating and two were found ashore) from this field between 12-14th August 1940, in time when the Mediterranean Fleet sailed on 16th August for operation M.B.2 (bombardment of Bardia) and crossed this area.

On 21st August, a mine was recovered with 250 fathoms of 3/4" mooring rope. The next day, at 1415 hours, HMS Loch Melfort believed she was in contact with a submarine, which was later thought to be one of the mines from this field, as the position was 320° - Ras El Tin - 13 miles. Four mines were found in 220 fathoms on 3rd September 1940. On 16th May 1941, Loch Melfort destroyed a mine, perhaps belonging to this field in 31°55' N, 29°31' E (which was much farther north than position reported). There also were mines laid from the air, but usually these were ground mines. Following the discovery of this minefield, British submarines were usually ordered to remain outside the 200 fathom line in Italian-controlled waters. The order remained in effect at least until December 1940, greatly reducing their effectiveness.

31° 59'N, 28° 32'EToward noon, the hydrophones picked up noises believed to be from a destroyer.

At 1340 hours, a destroyer was sighted and shortly after, a second one.

At 1358 hours, a single torpedo (533mm, S.I. H type) was fired from a stern tube at a distance of 800 metres, aimed at the first of the two destroyers. A violent explosion was heard after 40 seconds. The torpedo actually missed.

This was a squadron consisting of the light cruisers HMAS Sydney and HMS Neptune, escorted by the destroyers HMS Nubian, HMS Mohawk, HMS Hostile and HMS Imperial. HMS Nubian sighted a torpedo approaching and avoided it. Nubian and Hostile were left behind to hunt the submarine, but made no ASDIC contact.

(0) 40 miles SW of Cape Matapan.
At 0327 hours, the Officer of the Watch sighted four shadows on the starboard bow, which proved to destroyers at a distance of 13-14,000 metres, steering 100°, followed shortly after by three other destroyers and more. The submarine closed on the surface, but visibility was excellent and she had to submerge at 0335 hours to avoid being seen.

At 0355 hours, one torpedo was fired from a bow tube aimed at one of the destroyers. It was fired at the limit of the weapon's range (probably 4,000 metres) and T.V. Guido D'Alterio's view through the periscope was continuously hampered by continuous drops of oil leaking from the Calzoni system. The torpedo missed.

At 0400 hours, the submarine was turned for a stern shot. D'Alterio intended to fire a 533mm as it could be angled (the 450mm could not) but at the critical moment the torpedo misfired as the launching valve failed to open. He gave up the attack and brought down his submarine to a depth of 40 metres.

The targets may have been HMS Nubian, HMS Mohawk and other destroyers.

5D'Alterio, Guido30 Mar 19410800Taranto5 Apr 19410850Leros930Supply mission to Leros carrying passengers and material for the Royal Italian Army and 140 tons of benzine for the Italian Navy. Stern damaged following the explosion of a torpedo which was accidentally discharged while entering Leros.
  3 Apr 1941040034° 10'N, 25° 24'EAt 0353 hours, a lookout spotted a shadow on the port bow. Shortly after, a single-funnel cruiser could be discerned, followed by a number of merchantmen, steering 320°.

At 0400 hours, four torpedoes were ordered fired from the bow tubes at a range of 1,500-2,500 metres, two aimed at the cruiser and two at merchantmen. Only two left the tubes, the others misfired. Two loud explosions were heard. Actually both torpedoes missed.
  5 Apr 19410518
(0) Near Porto Lago.
At 0518 hours, as the submarine arrived at the entrance of Leros, a torpedo was accidentally fired from a stern tube and exploded shortly after, causing serious damage to her stern. Pietro Micca was towed to Leros and temporarily patched up, then sailed for Taranto for repairs. The claim that she was attacked by an enemy submarine is not substantiated.

  30 Nov 1941122036° 52'N, 19° 09'EAt 1220 hours, in poor visibility, an Italian squadron was encountered and it apparently included a destroyer of the SOLDATO class. Pietro Micca was mistaken for enemy and attacked with depth-charges. She was damaged but escaped by diving to 85-90 meters and was forced to go to Benghazi instead of Derna.

This was probably the Italian 7th Cruiser Squadron, which had made a sortie in the Central Ionian Sea. It consisted of the light cruiers Emanuele Filiberto Duca D'Aosta, Raimondo Montecuccoli, and Muzio Attendolo escorted by the destroyers Aviere, Geniere and Granatiere.

39° 45'N, 18° 17'EAt 0605 hours, Pietro Micca was returning to Taranto when two torpedo tracks were sighted. The first was avoided, but the second hit just aft of the conning tower and the submarine sank very quickly.

The culprit was the submarine HMS Trooper (Lieutenant G.S.C. Clarabut, RN). Two objects had been sighted at 0638C hours, in poor visibility. At 0645 hours, this was identified as a MARCELLO class submarine at a distance of 4,800 yards, steering 330° at 11-15 knots. The British submarine was handicapped because her ASDIC was out of action and enemy speed had to be estimated. The Italian submarine was then observed to alter course to 275°.

At 0654.5 hours, six torpedoes were fired at range of 4,600 yards and one hit was heard. A torpedo was a circler and missed the British submarine by passing over her stern so the result of the attack could not be observed.

Eighteen survivors (including T.V. Paolo Scrobogna) were picked up by the pilot vessel Vincenzo Dormio (F.81, 217 tons, built 1917), sent to escort her in, which arrived on the scene just after the attack. Two officers and fifty-two ratings perished. A number of vessels were immediately dispatched to attempt a rescue as it was believed that some survivors were in the forward section. These were the corvettes Sfinge, Pomona, Scimitarra and Driade and the auxiliary Monella (A.S.200). The submarine Onice was also sailed but was eventually diverted to Gallipoli.

Sfinge sailed from Taranto at 1125 hours, bringing several specialists with her, including Capitano G.N. Galbo (who had served on Micca) and five deep sea divers. The corvette reached the spot at 1600 hours, where she found Bormio, the auxiliary Monella and two minesweepers already there to give any assistance. The soundings by Sfinge revealed that the wreck was at a depth of 84 metres. The divers declared that this was beyond their capabilities and, reluctantly, the effort was abandoned.

In 1995, the wreck of Pietro Micca was located 2.5 miles - 241 ° from Santa Maria di Leuca or approximately 39°47' N, 18°18' E in 82-84 meters of water.
