1Caprile, Francesco10 Jul 19430500Bonifacio11 Jul 19432130Sunk with all handsSailed via Cape Figari (ca. 41°00'N, 10°00'E) for patrol in area 171 [between 38°15'N and 38°25'N, and between 12°00'E and 12°20'E] [Velella and Argo were to patrol next to her in 172 and 173].

However, the same evening, she was ordered to proceed via 39°00'N, 15°00'E and Point M3 to area 84 [between 36°40'N and 36°50'N, and between 15°20'E and 15°40'E].

She was reported to have crossed the Strait of Messina at 1705 hours on the 11th. She had done about 400 miles in 40.5 hours. Probably sunk off off Catania by British motor torpedo boats MTB 640, MTB 651 and MTB 670 in 37°34'N, 15°43'E (six officers and forty-three ratings killed, no survivors). At 0007 hours on the 14th, MARICOSOM, unaware of her loss, ordered her to occupy the southern half of zone 81 [between 37°10'N and 37°15'N, and between 15°20'E and 15°40'E].

On 16th July, she was ordered to an area between 37°20 and 37°40'N, and between 15°40'E and the Sicilian coast.

On 20th July, she was ordered to return to La Maddalena via the Strait of Messina with an ETA of 23rd July but failed to show up.

(e) 34° 34'N, 15° 43'E
At 2130 hours, the British motor torpedo boats MTB 640 (Lt. R.R. Smith, RN), MTB 651 (Kenneth Horlock) and MTB 670 of the 32nd MTB Flotilla were carrying an offensive patrol off Catania, when a surfaced submarine was attacked. The submarine tried to fight off the attack and, according to the British eyewitnesses, she returned very effective fire with a machine gun on the conning tower before diving. She inflicted seventeen casualties on the MTBs. MTB-651 had one wounded (the coxwain), the distribution of casualties on the other two boats is not known. The MTBs fired torpedoes which missed and dropped depth charges. The submarine was believed to have been seriously damaged. Our thanks to Ken Gadsdon who served on MTB-651 and provided an eyewitness account to the action.

This submarine could only be Flutto. She may have been sunk in this encounter as no subsequent news were received from her. T.V. Francesco Caprile, five officers and forty-three ratings perished, there were no survivors.

(0) 24° - Cape Peloro - 11 miles
At 1510 hours, a submarine was sighted and reported to MARICOSOM.

This was HMS Ultor (Lieutenant G.E. Hunt, DSC, RN). She had sighted the Italian submarine, unescorted and steering 180° at 10 knots. The British submarine had instructions to reserve her torpedoes for cruisers and battleships in case the Italian Battle Fleet sailed to interfere with the landings in Sicily. She could only carry out a dummy attack on Flutto. For the Italian submarine, this was a reprieve of only a few hours.
