Patrols and events

	Commander	Date	Time	Port	Arr. date	Arr. time	Arr. port	Miles	Description
	Galletti, Raul	10 Jun 1940		Tobruk	18 Jun 1940		Tobruk		At Tobruk.
		12 Jun 1940	0340+	(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.
1	Galletti, Raul	18 Jun 1940	2141	Tobruk	22 Jun 1940	0856	Tobruk	367	Patrolled 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 1940	0457	(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, Raul	25 Jun 1940	2025	Tobruk	30 Jun 1940	0940	Crotone	553	Passage Tobruk-Taranto via Crotone for repairs.
		27 Jun 1940	1715	(0) ?	At 1715 hours, a bomber was seen apparently flying from Malta to Alexandria. Sirena quickly dived to 50 metres.
		28 Jun 1940	1215	(0) ?	At 1215 hours, a smoke was sighted on the horizon. Sirena dived to listen on her hydrophones, picking up noises.
		28 Jun 1940	1244	(0) ?	At 1244 hours, two aircraft were observed through the periscope, flying toward the submarine. Sirena was taken down to 50 metres.
		28 Jun 1940	1735	37° 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 1940	0630 0635 (e)	37° 54'N, 18° 04'E	At 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 1940	0150	38° 06'N, 18° 02'E	At 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.
