Patrols and events

---|---|---|---|---|---|---|---|---|---|---|
1 | Aicardi, Giuseppe | 9 Jun 1940 | 0740 | Leros | 14 Jun 1940 | 1540 | Leros | 439,1 | Patrolled in Kaso Straits in 34°48'N, 27°18'E on a patrol line with Jalea and Jantina. | |
2 | Aicardi, Giuseppe | 19 Jun 1940 | 0947 | Leros | 26 Jun 1940 | 1110 | Leros | 353 | Patrolled in Scarpanto Channel between Scarpanto Island and Prassonisi. Uneventful. Route: (a) in 121° - Kandeluisa - 2.5' (1332/19) (b) 163° - Cape Monolito - 6.5' (1650/19)(c) 190° - Prassonisi - ? (1826/19). Patrolled off Prassonisi until 25th June in a static position. | |
3 | Aicardi, Giuseppe | 15 Jul 1940 | 2040 | Leros | 22 Jul 1940 | 0730 | Leros | 533,5 | Patrolled in Doro Channel within 5 miles from 38°10'N, 24°50'E. | |
18 Jul 1940 | 0100 | 38° 10'N, 24° 50'E (0) Approximately. | Two torpedo tracks were observed and they missed 50 metres ahead. The "attack" was most likely bogus, as no enemy submarine operated in the vicinity. The "torpedoes" were probably porpoises. | |||||||
18 Jul 1940 | 0515+ | 38° 16'N, 24° 47'E (0) Doro Channel. | A submarine was sighted at a distance of 2,700 metres and one bow torpedo (533mm) was fired, claiming a hit after 123 seconds. Aicardi claimed that the enemy "submarine" had fired a torpedo at him before he replied. A large oil patch was observed, but the attack was certainly on a non-sub target as no British or Hellenic submarine operated in the area. Italian Naval Intelligence believed that his target may have been HMS Orpheus as a British communiqué had announced her loss on 17th August. On 29th August 1940, Aicardi was awarded the Bronze medal for "his attack on an enemy submarine on 18th July". | |||||||
4 | Aicardi, Giuseppe | 14 Aug 1940 | 2049 | Leros | 17 Aug 1940 | 1900 | Leros | 341 | Sailed for a special mission, under the orders of Governor De Vecchi, and patrolled off Tinos Island, sank the Greek cruiser Helle. | |
15 Aug 1940 | 0830 (e) | (0) Gulf of Aigina (Tinos Island). | At 0430 hours, Delfino submerged and closed the harbour of Tinos at periscope depth. At a distance of 4,000 metres from the entrance, a steamer was observed sailing northward and could not be attacked. Two steamers of 6-8,000 tons were in the harbour as well as a Greek warship (the 2,115-ton light cruiser Elli). The presence of the warship was also reported earlier by a seaplane of 7/185 Squadriglia based at Leros. At a distance of 700 metres, a bow torpedo (533mm) was fired and squarely hit the cruiser, which sank quickly. A second torpedo (533mm) was fired from a stern tube to finish off the Hellenic cruiser, but missed. Nine were killed, there were 197 survivors including twenty-four wounded. Another torpedo (450mm) was fired from the stern tube, this time aimed at the passenger ships Elsi (1,433 GRT, built 1891) and Esperos (1,461 GRT, built 1918) both anchored in the harbour, but it also missed. This brazen infringement of Greek neutrality was long denied by the Italians, who blamed the British for the attack. Fragments of the torpedo bearing a "TORRINO 1930" marking were recovered by the Greeks. They are on display at the Piraeus Maritime Museum. This action may have been in retaliation for alleged Greek involvement in the sinking of the Greek small tanker Ermioni (chartered by Governor De Vecchi) by HMS Neptune (28th July 1940). In fact, British Intelligence had reported the passage of the vessel through the Corinth Canal. In 1950, the light cruiser Eugenio di Savoia was ceded to Greece as war reparation and renamed Helle. She was in service from 1951 to 1965 and scrapped in 1973. | |||||||
15 Aug 1940 | 1130 | (0) Syra harbour. | Delfino examined Syra harbour, but it was empty of shipping. | |||||||
16 Aug 1940 | 0100 | (0) Southern entrance of Zea Channel. | A small local vessel was observed, but the attack was aborted as it was not worth the expenditure of a torpedo. | |||||||
16 Aug 1940 | 0530 | (0) St. Nicolo harbour (Zea). | The harbour was examined but was empty of shipping. | |||||||
16 Aug 1940 | 1830 | (0) 10 miles NE of S. Giorgio. | A convoy of five large loaded ships, including a large two-funnel liner with a British EXETER class cruiser, was observed from a distance of 7-8,000 metres but was too far to intercept. During the night Supermarina ordered Aiccardi to cancel his patrol. | |||||||
5 | Aicardi, Giuseppe | 20 Sep 1940 | 1757 | Leros | 26 Sep 1940 | 1700 | Leros | 562,5 | Patrolled 8 miles east of Cape Malea and 20 miles east of Cape Spada. Unevenful. | |
6 | Aicardi, Giuseppe | 27 Oct 1940 | 1900 | Leros | 6 Nov 1940 | 0815 | Leros | 699,5 | Patrolled northeast of Doro Channel in 065° - Kalogeri Island - 17 miles. Uneventful patrol marked by poor visibility. | |
7 | Avogadro di Cerrione, Alberto | 24 Nov 1940 | 0030 | Leros | 1 Dec 1940 | 0810 | Leros | 598 | Patrolled north of Aegean, off Tinos Island. | |
28 Nov 1940 | 1320 | (0) Off Cape Drepano. | The submarine heard two noises, with hydrophones. These were believed to be from two enemy submarines, but none were sighted. | |||||||
29 Nov 1940 | 1836 | 39° 09'N, 25° 01'E (0) 175° - Cape Tripti - 18 miles. | A submarine of the KATSONIS class was sighted at a distance of 800-1,000 metres, but she dived before an attack could be mounted. No Hellenic submarine operated in the area. | |||||||
29 Nov 1940 | 2320 2330 (e) | 38° 12'N, 25° 01'E (e) 38° 12'N, 25° 04'E (0) 102° - Kalojeri Reef - 12 miles. | The submarine was surfaced when a Greek convoy of two steamers, escorted by three destroyers, was sighted proceeding at a speed of 10 to 12 knots. Two stern torpedoes (one 533mm and one 450mm) were fired from a distance of 1,200 metres at one of the destroyers and Delfino dived. Two explosions were heard and a destroyer claimed sunk. The convoy included the destroyers Spetsai, Vasilissa Olga, Kondouriotis, Vasilefs Georgios (Leader) escorting the merchants Asimina Baika, Sonia, Marit Maersk and Heron. They were heading in ballast to Chios and Lesbos in order to embark mobilization personnel and material, except Heron who was on a commercial route to Smyrna. The torpedoes passed close to Spetsai and the submarine was spotted on the surface before diving. The depth charges of Spetsai failed to detonate. | |||||||
8 | Avogadro di Cerrione, Alberto | 3 Jan 1941 | 2000 | Leros | 11 Jan 1941 | 0830 | Leros | 640 | Patrolled between Cape Sidero and Suda or zone C for CESARE West. | |
6 Jan 1941 | 2200 | (0) Off Suda Bay. | A destroyer squadron was sighted at a distance of 10,000 metres but passed out of range. | |||||||
Avogadro di Cerrione, Alberto | 1 Feb 1941 | 1815 | Leros | 6 Feb 1941 | 1030 | Brindisi | 827 | Passage Leros-Brindisi. Uneventful. | ||
Avogadro di Cerrione, Alberto | 8 Feb 1941 | 1200 | Brindisi | 9 Feb 1941 | 1700 | Pola | 362 | Passage Brindisi-Pola. | ||
9 Feb 1941 | 1000 | 43° 07'N, 14° 05'E | An Italian merchant vessel was seen approaching on an opposite course from a distance of 6,000 metres. This was Stamira (1,463 GRT, built 1929). Despite repeated signals from Delfino identifying herself, the merchant ship turned back and apparently fired a round at the submarine, although the fall of shot was not observed. Marina Ancona was criticized for failing to warn Stamira of the possible encounter with an Italian submarine. | |||||||
