  20 Nov 19402000
(0) South of Crete?		At 2000 hours, an illuminated convoy was sighted and identified as French.
  23 Nov 19401605-2130
(0) About 90 miles NW of Alexandria.		At 1605 hours, an aircraft carrier, four cruisers and three destroyers were sighted at a distance of 20,000 metres, steering 330°. These were probably HMS Eagle, the battleships HMS Malaya and HMS Ramillies with cruisers and destroyers. They had sailed from Alexandria to cover the convoy M.W.4, destined for Malta (operation MB.9).

Onice remained submerged, going deep to use her hydrophones, occasionally coming to periscope depth with the result that no attack was possible and contact was finally lost at 2130 hours. T.V. Lovatelli was criticised by Admiral Falangola (Head of MARICOSOM) for his cautiousness.

2Lovatelli, Gustavo19 Dec 19402000Leros31 Dec 19400719Leros1312Patrolled in Aegean between 35°20'N and 35°40'N, and between 24°00'E and 26°20'E. Uneventful.

3bLovatelli, Gustavo6 Mar 19411730Maltezana Bay (Stampalia)9 Mar 19410826Portolago (Leros)366,5Patrolled north of Crete in 35°40'N, 25°50'E.
  8 Mar 19410200+35° 36'N, 25° 47'EAt 0200 hours, a shadow was sighted which was believed to be an enemy cruiser. Shortly after, two torpedoes were fired at a range of 2,000 metres. They missed.

This was most probably one of the three cruisers of 7th Squadron (HMS Orion, HMS Ajax and HMAS Perth) on passage from Alexandria to Piraeus where they arrived at noon on the same day. The attack was unobserved.

Lovatelli, Gustavo18 Mar 19411340Portolago (Leros)18 Mar 19411402Portolago (Leros)0Engine tests.

4Lovatelli, Gustavo2 Apr 19412350Portolago (Leros)17 Apr 19410815Portolago (Leros)1470Patrolled on northwest of Alexandria. Within 20 miles from 32°40'N, 28°00'E on a NE-SW axis (north of Mersa Matruh).
  6 Apr 1941010032° 40'N, 28° 00'E
(0) Approximate position.		At 0100 hours, as the submarine was diving, it was realised that torpedo tube no. 6 cap was not properly closed and was leaking. Onice surfaced and rating Michele Piscopo volunteered to dive overboard and after 15 minutes managed to correct the problem and the patrol resumed.
  10 Apr 19412005At 2005 hours, by bright moonlight, a naval formation was sighted. It consisted of two large and two small ships. Onice proceeded at full speed on the surface but appeared to have been spotted by a destroyer. She crash-dived and had reached a depth of 40 metres, when nine depth charges exploded but caused no damage.

This was convoy A.S.F.24: the transport Breconshire escorted by the destroyers HMS Hotspur and HMS Havock proceeding from Piraeus to Alexandria. It was HMS Hotspur who sighted the submarine and briefly hunted it for 20 minutes before rejoining the convoy.
  13 Apr 19411910At 1910 hours, two merchant ships were sighted at 10,000 metres. Onice submerged to intercept but could not close the range to attack.

5Lovatelli, Gustavo16 May 19411340Portolago (Leros)31 May 19411728Portolago (Leros)1332,5Patrolling in Aegean in 35°08'N, 26°47'E. On 27 May, shifted to 240° - 50 miles in 34°40'N, 25°53'E.
  17 May 19412018
(0) Near Scarpanto.		At 2018 hours, information was received of a naval formation sighted at 1455 hours about 60 miles away. As the amplifier of the hydrophones had broken down between 1330 and 1600 hours, nothing was heard. A further signal was received at 2355 hours of a large enemy formation, but this was outside Onice's patrol area.
  19 May 19412247
(0) Near Kaso.		At 2247 hours, Onice received a signal from Galatea, reporting a naval formation proceeding toward Kaso Straits about 18 miles from her. C.C. Lovatelli gave up the chase as he believed that this formation was one hour ahead of him and the prospect of catching up were slim.
  21 May 19410115
0218 (e)		35° 18'N, 25° 03'EAt 1915 hours on 20th May, noises were heard of a vessel proceeding slowly toward the submarine. As Onice was going up to periscope depth, at a depth of 15 metres a pattern of depth charges exploded very close. More followed at variable distances. At 2200 hours, the submarine surfaced and proceeded toward Skarpanto.

At 0112 hours on 21st May, three shadows of destroyers were sighted.

At 0115 hours, three torpedoes were fired from the bow tubes at a distance of 2,000 metres. Two hits were claimed. Actually, all torpedoes had missed.

The targets were the destroyers HMS Jervis (D.14), HMAS Nizam and HMS Ilex (Force E) sent to bombard the Scarpanto aerodrome. HMAS Nizam reported being missed by a torpedo and explosions were heard at 0221, 0224 and 0227 hours which were most likely caused by torpedoes at the end of their run.

The rest of Onice's patrol were punctuated by many H.E. and distant explosions.

  17 Sep 1941165834° 25'N, 18° 14'EAt 1658 hours, a convoy of three steamers, escorted by four destroyers, was sighted at a distance of 16,000 metres, steering 240-250° at 12 knots.

Onice submerged to try an attack, but was depth charged by a destroyer from 1705 to 1734 hours. Twenty-five depth-charge explosions were counted, but they were distant.

7Albanese, Loris18 Sep 19411900Benghazi19 Sep 19410700Benghazi23Antisubmarine patrol in 023° - Benghazi Light - 18 miles. Uneventful. The first of 25 one-night patrols carried out of Benghazi. Thirteen were passive (lying off Benghazi. listening to her hydrophones), four were search patrols carried out with submarine chasers (Zuri, Selve and Zirona), two were search patrols with torpedo boats and six were search patrols carried out independently.

  25 Sep 1941004532° 25'N, 19° 45'EAt 0045 hours, a suspect shadow was sighted on the port bow. As the submarine chasers Zuri and Zirona were known to be astern. Onice submerged to get contact with the hydrophones and be in a better position for an attack. The hydrophones picked up the contact for the next hour or so. At 0204 hours, Onice made a signal to the submarine chasers. At 0240 hours, two torpedo boats were seen proceeding toward the trio. These were the torpedo boats Orione and Centauro escorting the freighters Capo Faro and Iseo. They arrived at Benghazi at 0620 hours.

This was almost certainly HMS Thrasher who attacked the convoy at 0202 hours. Her attack was unobserved.

This was HMS Regent (Lieutenant W.N.R. Knox, RN). The Italian submarine was mistaken for a destroyer and she crash-dived. She had already escaped a dive-bombing attack at 0250 hours.

At 0451 hours, Onice made an enemy report and returned to Benghazi.

  11 Mar 19421445
(0) NE of Malta.		At 1006 hours, Onice (and Uarsciek) had been informed that an enemy force of three cruisers, five destroyers and four auxiliaries had been sighted, at 0745 hours in Italian Grid 6719 (34°20' N, 22°25' E), steering 285°, 22 knots. This was followed by more signals.

At 1445 hours, two aircraft were sighted steering 270°. Onice dived.

11Zelik, Bruno15 Mar 19421903Messina31 Mar 19420755Messina1517,3Patrolled north of Cyrenaica between 34°30'N and 34°40'N, 22°10'E and 23°10'E.
  16 Mar 19420120
0115 (e)		37° 29'N, 16° 32'EAt 0120 hours, a submarine was sighted at a distance of 800-1,000 metres. Shortly after, Onice fired two torpedoes from her bow tubes at a range of 500 metres. She then opened fire as she steered straight for the enemy. After the third round, fired at only 150 metres, the submarine crash-dived as Onice passed over her.

This was HMS P 36 (Lieutenant H.N. Edmonds, DSC) who mistook Onice for an E-boat which fired two bursts above the submarine. HMS Unbeaten was in an adjacent area and heard two loud explosions at 0130 hours but these were probably the torpedoes hitting bottom.
  17 Mar 19421315
(0) West of Crete.		At 1315 hours, Onice was suddenly attacked by a German aircraft, which strafed her. The submarine made the recognition signal and the aircraft flew away. At 1330 hours, two more aircraft were sighted and this time Onice dived immediately.
  21 Mar 1942161434° 18'N, 22° 54'EAt 1614 hours, in poor visibility, a convoy was sighted at a distance of 3,000 metres. Onice submerged, but immediately lost contact.
  23 Mar 1942143334° 14'N, 22° 26'E
(0) Italian Grid 5806/2.		At 1342 hours, noises were detected with hydrophones. At 1415 hours, an enemy squadron could be seen at 7-8,000 metres. It consisted of three destroyers leading three or four cruisers, flanked by more destroyers.

At 1433 hours, two torpedoes were fired from bow tubes with the destroyer screen at a distance of 1,800 metres and the cruisers at 2,500-3,000 metres. The "senzabolla" (bubbleless) system did not work and C.C. Zelik decided to take his submarine to a depth of 40 metres. At 1436 hours, an explosion was heard and a torpedo was assumed to have hit. The explosion was also heard in Platino who was in the area.

This was most probably the 15th Cruiser Squadron retiring to Alexandria after the Second Battle of Sirte. The attack does not seem to have been observed and the torpedoes missed.
  23 Mar 1942150634° 14'N, 22° 02'E
(0) Italian Grid 5806/2.		At 1506 hours, a cruiser and destroyer were sighted on an opposite course at a distance of 5,000 metres. Onice lost contact but sighted them again at 1602 hours, this time at a distance of 8-10,000 meters.

At 0345 hours, two torpedoes were fired. One of them porpoised and both missed. The rough seas prevented Onice from carrying a gun action and the enemy submarine dived at 0347 hours.

No enemy submarine operated in the area. Either Onice attacked Corallo by mistake or the "submarine" was perhaps a fishing vessel. At the same time,in the adjacent area, Corallo was in the process of sinking of the Tunisian fishing vessel Tunis and she did not dive as reported by C.C. Zelik.
  9 May 19422114
(0) 2 miles north of Cape Bon.		At 2114 hours, Onice was strafed by an aircraft and crash-dived.

  15 Jun 19421217At 1217 hours, information was received of an enemy convoy of fourteen ships had been sighted in Grid 8331/2, steering 090°. Shortly after, this was corrected to 120°, 8 knots. Onice surfaced and altered course to 060° to intercept. This was the HARPOON convoy proceeding from Gibraltar to Malta.
  15 Jun 19421307At 1307 hours, an aircraft was seen and Onice dived.

At 1405 hours, information was received that the enemy convoy was still in Grid 8331 but now steering 120°, 8 knots.

  15 Jun 19421707At 1707 hours, a steamer was sighted on the horizon at a distance of 20,000 metres, proceeding at 10 knots.

Onice proceeded to attack and sighted three large steamers, escorted by four destroyers, steering 040° at 10 knots. At 1815 hours, the range had closed only to 9,000-10,000 meters and it became evident that they would pass out of range. At 1856 hours, the submarine surfaced and made an enemy report.

  7 May 19431740
1841 (e)		34° 26'N, 23° 10'EAt 1740 hours, three bombers were seen and Onice crash-dived. She had reached a depth of 20 metres, when three bombs exploded, causing no damage.

These were three Baltimore of 454 Squadron (RAAF), returning to base after an uneventful anti-shipping sweep of the Aegean Sea.

At 1841C hours, the leading aircraft (AH158) piloted by Flight Lieutenant M. Moore sighted a fully surfaced U-boat, steering 250° at 7 knots. The submarine began an immediate crash dive. The Baltimore dived to attack and, from 1000 feet, dropped two 250 lb. General Purpose bombs with a three second delay, just as the periscope was seen to submerge. The bombs overshot by about 50 yards. The second aircraft, (AG869) piloted by Sergeant D. Todhunter, while at extreme range, fired a short burst from its forward guns at the submerging U-boat. As the three aircraft were short of fuel, they could not linger on the scene and returned to base.
