  1 Jul 19400458
(0) 30 miles SW of Pantelleria.
At 0455 hours, a shadow was sighted, which appeared to be a submarine very similar to Fieramosca. At 0458 hours, one torpedo (533mm) was fired from a bow tube at an estimated distance of 1,600 metres. It missed. This was probably HMS Proteus (Lt. Cdr. R.T. Gordon-Duff, RN), which had left her patrol south of Malta and was on her way to Oran to participate in Operation CATAPULT, but she did not observe the attack.
  1 Jul 19400500
(0) 30 miles SW of Pantelleria.
A second torpedo (533mm) was fired from a bow tube at a distance of 1,400 metres but again it missed.

  13 Mar 19410355
(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.

8.Pietro Micca (MC)30 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.

  22 Jul 1941222034° 47'N, 19° 43'EAt 2220 hours, a Sunderland was sighted. It flashed the signal "O" and the submarine replied with "U". The sunderland came back and signalled "U" and this time the submarine replied with "O". The aircraft appeared to have been satisfied and flew away.
  23 Jul 1941220033° 00'N, 22° 36'EAt 2200 hours, a small vessel was sighted on a westerly course. Atropo made an enemy report.

  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.
