1.Zoea (ZE)25 Jun 19421000Taranto28 Jun 19422030DernaSupply mission to Derna (53 tons of petrol and 3 tons of food supplies). ULTRA sigint had learnt that Italian submarines Atropo, Bragadino, Corridoni and Zoea used to transport stores to Derna were passing through 33°20’ N, 22°40’ E.
  27 Jun 1942150533° 49'N, 22° 33'EAt 1505 hours, a submarine was sighted and believed to be Atropo. Zoea had instructions not to attack submarines encountered. She was sighted by HMS Thrasher the next morning when approaching Derna, but the British submarine could not get into an attacking position.

2.Zoea (ZE)29 Jun 19420015Derna2 Jul 19421100Taranto1047Return trip from supply mission to Derna. ULTRA sigint had learnt that Italian submarines Atropo, Bragadino, Corridoni and Zoea used to transport stores to Derna were passing through 33°20’N, 22°40’E. In fact, they were informed that Zoea was due in Derna on the 27th, but it was on her return trip that the interception was made.

34° 20'N, 22° 40'EAt 1430 hours, an aircraft was sighted astern and remained at a distance.

At 1500 hours, an aircraft was sighted making a long circle at low altitude and it made an attack from the sun. It tried strafing the submarine without managing to hit her. Zoea opened fire with her machine guns and even with her deck gun. The aircraft was believed hit and flew away.

This was Maryland 'P' (No. 364) of 203 Squadron piloted by Pilot Officer E. Boyce, on a special search for enemy craft south of Crete. At 1629C hours, it sighted the submarine on the surface, steering 280° at 8 knots. Zoea opened fire but her shots fell astern. The aircraft replied with its guns but without any apparent effect. The Italian flag was seen to be flying. The submarine was still on the surface when the aircraft departed.

At 1830 hours, Zoea had unloaded her stores when a heavy air raid by the USAAF was witnessed. A heavy bomb fell a few metres from the conning tower on the starboard side, while a pontoon loaded with ammunition suffered a direct hit 200 meters away. The submarine suffered some damage from the near-miss but this was not noticed at the moment. Following the explosions of the ammunition on the pontoon, the First Officer ordered the submarine away.

She rescued twenty Germans whose aircraft had been shot down and landed them at Tobruk.
  3 Nov 19420625-1200During the period of 0625-1200 hours, many German aircraft were seen. Ascianghi exchanged recognition signals on eight occasions during the morning.
  3 Nov 19421330+
(0) Off the Libyan coast.
At 1330 hours, a formation of eighteen German transport aircraft (probably Junkers 52) were observed flying to Libya. One of them suddenly began to gradually lose altitude and crashed into the sea. Ascianghi rushed in heavy seas and managed to pick up twenty German survivors, including several wounded. They were later landed at Tobruk.

At 1600 hours, two Germans seaplanes were sighted, apparently looking for survivors. The submarine signalled them that she had picked them up.

14.Ascianghi (AS)9 Nov 19420217Trapani18 Nov 19420957Naples1580Patrolled off Bougie and Philippeville, between 37°00'N and 37°20'N, 05°55'E and 06°35'E. Then refit at Naples.
  12 Nov 1942003036° 44'N, 5° 10'EAt 0030 hours, a corvette was sighted. Ascianghi crash-dived at dropped to the bottom at a depth of 57 metres.

(e) 36° 43'N, 5° 12'E
(0) Off Bougie.
At 0800 hours, Ascianghi had dived to the bottom, which this proved very muddy and, she became stuck. As efforts were being made to free the submarine by blowing the ballasts, she was sighted by the frigate HMS Spey at 0810A hours. She was also sighted at 0855 hours by the destroyer ORP Blyskawica which was oiling from the tanker Dewdale (8,265 GRT, built 1941). At 0900 hours, the Polish destroyer observed two trawlers and three sloops (one of them probably HMS Spey) depth charging the submarine and joined the hunt, dropping four depth charges at 0912 hours. At 0951 hours, ORP Blyskawica followed up with two more attacks, delivering five depth charges each time.

Ascianghi reported about 100 depth-charges dropped in all but managed to escape by going down to a depth of 70-80 meters. Since the harbour and anchorage were under heavy air attacks during the day (1110-1153, 1440, 1521 hours), it is possible that the submarine mistook these for depth-charges.
  15 Nov 1942034236° 45'N, 5° 11'EAt 0339 hours, Ascianghi was about 4 miles from then entrance of the harbour of Bougie, when the stern lookout spotted a dark mass. At first, it was believed it could be a submarine but then was identified as a CALEDON class cruiser with two destroyers.

At 0342 hours, she fired two torpedoes from her stern tubes at a range of 3,300 metres, but it was then realised that the cruiser was proceeding at a slower speed than estimated, causing them to miss ahead. After 167 seconds, an explosion was heard, which T.V. Rino Erler assumed to be that of the torpedo having hit another vessel. Immediately after, G.M. Ansaldo drew Erler's attention to another ship in the vicinity.

At 0346.5 hours, the newcomer was identified as a cruiser of the LEANDER class and two torpedoes were fired (533mm, Italian type, speed 46 knots), aimed at it, at a range of 700 metres. Both torpedoes hit, after 30 seconds with a loud explosion,followed shortly after by a third explosion, believed to have been caused by a boiler blowing up. The vessel was broken in two and sank.

The "cruiser" was actually the minesweeper HMS Algerine (J213, 1,040 tons, Lieutenant Commander Wilfrid Alan Cooke, RN) ). Survivors confirmed that she was struck by two torpedoes and sank in five minutes. Nine officers and seventy-one ratings were killed or missing. Thirty-two survivors were picked up by the minesweeper HMS Cadmus. Seventeen survivors were picked up by H.M. ships HMS Alarm, HMS Hoy and HMS Mull. Four died of their wounds.

  22 Feb 1943230032° 03'N, 16° 04'EAt 2300 hours, an escorted convoy was sighted at a distance of 5,000 metres. Ascianghi closed to about 2,000 meters and dived at 2307 hours but lost contact.
  2 Mar 1943023131° 47'N, 16° 43'EAt 0227 hours, the First Officer, who was Officer of the Watch, alerted T.V. Erler that he had a destroyer and an undetermined number of merchant ships in his sights, steering 300°, 12 knots.

At 0231 hours, three torpedoes (533mm) were fired from the bow tubes at a range of 800 metres aimed at the destroyer described as of the JERVIS classs. A fourth torpedo misfired. Ascianghi immediately crash-dived. After 40.5 seconds, she had reached a depth of 16 metres, when a double explosion was heard followed by a third one after 73 seconds. This led Erler to believe he had hit the destroyer with two torpedoes and a merchant ship behind with the third.

Unfortunately, Allied records have not confirmed these claims.
  4 Mar 19430755At 0755 hours, a Blenheim bomber was sighted at a distance of 5,000 metres. Ascianghi dived.
