(0) At Tobruk.
At about 0340 hours, Sirena was anchored in Tobruk harbour when she came under air attack. She was near-missed but undamaged.

1Galletti, Raul18 Jun 19402141Tobruk22 Jun 19400856Tobruk367Patrolled in Gulf of Sollum, 20 miles north of Ras Uleima, between 32°00'N and coast of Cyrenaica, and between 25°20'E and 27°20'E. Forced to break off patrol after being depth-charged on 21st June.
  21 Jun 19400457
(0) Probably 20 miles north of Ras Uleima.
At 0457 hours, Sirena was proceeding at a depth of 45 metres when she was badly shaken by a depth charge. She was taken down to 80 metres. Until 1220 hours, 36 depth-charge explosions were heard.

Galletti, Raul25 Jun 19402025Tobruk30 Jun 19400940Crotone553Passage Tobruk-Taranto via Crotone for repairs.

At 1715 hours, a bomber was seen apparently flying from Malta to Alexandria. Sirena quickly dived to 50 metres.
  28 Jun 19401215
(0) ?
At 1215 hours, a smoke was sighted on the horizon. Sirena dived to listen on her hydrophones, picking up noises.
  28 Jun 19401244
(0) ?
At 1244 hours, two aircraft were observed through the periscope, flying toward the submarine. Sirena was taken down to 50 metres.
  28 Jun 1940173537° 03'N, 18° 43'E
(0) ?
At 1735 hours, Sirena surfaced, but two minutes later an aircraft was seen. She quickly dived to 50 metres.

At 1750 hours, underwater signals were received, emitted from a distance of 4-6,000 metres, but Sirena did not answer.
  29 Jun 19400630
0635 (e)
37° 54'N, 18° 04'EAt 0630 hours, an aircraft was sighted at 3,000 metres, flying at an altitude of 500 metres. At first, it was thought to be Italian. As it closed, it was recognised as enemy and Sirena opened fire with her machine guns.

This was Sunderland 'Q' (L.5806) of 228 Squadron, piloted by Wing Commander G.E. Nicholetts. It dropped four A/S bombs, which straddled the submarine at distances of only 5-10 metres, but failed to explode. On a second run, two more A/S bombs were released, which fell 20 yards ahead of the submarine. T.V. Galetti believed that he had been attacked by two aircraft (perhaps not realising that both runs had been made by the same aircraft). He also believed that the first bomber had been repeatedly hit and one of its gunners mortally wounded as her strafing was very wild. He thought the first attacker had then been shot down. This was not the case and Nicholetts described the antiaircraft fire as completely ineffective.

At 0633 hours, Sirena crash-dived to 50 metres, as the aircraft was making its second run. She was not damaged and Galetti did not record any explosion on the second attack, so perhaps the last two A/S bombs were dud too.

For this action, T.V. Galetti was awarded the Madaglia d'argento.

  30 Aug 1940015038° 06'N, 18° 02'EAt 0150 hours, Sirena was proceeding on the surface when a submarine was sighted at 1,200 metres. She closed to 700 metres, but the attack was aborted as Ruggiero Settimo was known to be in the area. Afterwards, it was concluded that the submarine was enemy, but no British or Hellenic submarines operated in the vicinity.

  14 Apr 1941232736° 07'N, 24° 15'EAt 2324 hours, a destroyer of the AFRIDI class was sighted at 4-5,000 metres, steering 130° at 22 knots.

At 2327 hours, Sirena had closed on the surface to a distance of 2,300-2,500 metres and fired two torpedoes from bow tubes. No visible result was observed, but inside the submarine a hit was heard and it was believed the destroyer had been damaged. In fact, no British destroyer reported any damage at this time.

(0) Near Cape Malea.
At 1919 hours, information was received of an escorted convoy of three merchant ships, which had left Piraeus at 18 knots and of another convoy of thirteen ships from Alexandria, which was proceeding toward Cerigotto.

Sirena proceeded to a position 15 miles west of Cape Malea to intercept them, but only heard H.E. at a distance without sighting anything.
