1Spano, Mario9 Jun 19401500Tobruk14 Jun 19401350Tobruk482Patrolled off Sollum (Egypt), 030° - Ras Azzaz - 90 miles (or 80 miles?) (on a line with Lafolè, Diamante and Topazio, 20 miles apart).
  12 Jun 1940050332° 57'N, 26° 05'EAt 0458 hours, Nereide was at periscope depth when a 12-15,000-ton tanker was sighted.

At 0503 hours, one torpedo (533mm, W 270 type) was fired from a bow tube at a range of 500 metres. It was claimed to have hit. The tanker escaped in low visibility.

This was the Norwegian tanker Orkanger (8,029 GRT, built 1928) proceeding to Alexandria (and shortly after sunk by Naiade). She had initially sailed from Port Said for Malta. At the Italian declaration of war, she was ordered to turn back.

(0) Tobruk harbour.
During the evening, Nereide was at anchor in Tobruk harbour during an air raid. Her two machine guns fired 180 rounds of 13.2mm at two torpedo bombers who flew only 30 metres away. One of these was Swordfish E4H (lieutenant D.N. Collins, RN) of 813 Squadron from HMS Eagle, actually operating from Dekheila (an airfield just to the west of Alexandria)

At 2020 hours, the aircraft released its torpedo from 350-400 yards aimed at the submarine. Collins claimed that it hit its target and a column of 50-60 feet rose, but Nereide was missed. The Swordfish was hit by three machine gun rounds from the submarine and suffered only minor damage.

On 4th September 1940, Collins, flying the same Swordfish, was shot down by an Italian CR. 42 fighter while attacking the Maritza airfield (Rhodes). The crew of three survived to become PoWs.

(0) 230° - Cape Papas (Nikaria) - 8 miles
At 0053 hours, Nereide was cruising on the surface when a submarine was sighted at 6,000 metres.

At 0107 hours, she had closed to 700 metres, to fire two torpedoes from bow tubes at 3-second intervals. The second torpedo broke surface and disappeared. Immediately upon firing, the submarine turned to starboard to bring to bear her deck gun and opened fire with her machine guns. Shortly after, a column of water rose next to the enemy's conning tower and, as the submarine was disappearing, the deck gun scored a hit on the conning tower at less than 200 metres. T.V. Migliorini believed he had sunk the submarine and searched for survivors, but found none.

The submarine was HMS Tetrarch (Lieutenant Commander G.H. Greenway, RN). The confusion had not been one-sided, she was believed to have been attacked by two E-boats (MAS) and crash-dived. Two faint explosions had been heard and thought to be torpedoes hitting the sea bed. She was undamaged.

33° 58'N, 22° 58'EAt 1930 hours, a submarine's periscope was sighted and shortly after she surfaced. Nereide gained a favourable position and also surfaced. She made a recognition signal but the other submarine dived and C.C. Terra thought she was German.

This was actually the submarine HMS Porpoise (Lieutenant L.A.W. Bennington, RN) on passage from Malta to Alexandria. At 2050C hours, she sighted Nereide steering 090° and believed it was a German U-boat. She passed a warning to Captain S. One, in Alexandria. It was repeated to HMS Urge, who was expected to be astern of her some 50 miles to the west. HMS Urge had actually been mined off Malta.
  10 May 1942195634° 04'N, 23° 12'EAt 1956 hours, a submarine, believed to be German, was sighted at a distance of 1,200 metres. As a precaution, Nereide dived immediately.

At 0450 hours, in foggy weather, a submarine was sighted. As T.V. Scandola had not been informed of Italian submarines in the area, Nereide was prepared for action. Torpedoes and the deck gun were ready to fire when the submarine appeared to be Italian.

At 0459 hours, visual signals were exchanged and were also answered by a second submarine who was following. These were probably Nichelio and Wolframio who had sailed from Pozzuoli for Portoferraio.

26Scandola, Renato7 Jul 19430105Pozzuoli13 Jul 19430730SunkPatrolled south of Sardinia in 38°55'N, 09°25'E until 10 July, when ordered to patrol 40 miles east of Augusta. Sunk by HM destroyers Echo and Ilex 40 miles east of Augusta. Twenty-nine survivors. At 0007 hours on the 14th, MARICOSOM, unaware of her loss, ordered her to occupy the northern half of zone 81 [between 37°15'N and 37°20'N, and between 15°20'E and 15°40'E].
  12 Jul 1943174637° 30'N, 15° 10'E
(0) Approximate position. Near Catania.
This attack lacks details as Nereide did not return from this patrol.

At 1746 hours, a squadron of ten destroyers was sighted and three torpedoes (533mm, G7e type) were fired from bow tubes at 4,500 metres. Two destroyers were claimed to have been hit. These were probably units from the 5th Destroyer Flotilla.

At 0220 hours, Nereide was cruising on the surface when she was detected at a range of 10,200 yards by the radar of the light cruiser HMS Euryalus and, almost simultaneously, by the radar of the light cruier HMS Cleopatra. The warships were proceeding in company with the destroyers HMS Echo and HMS Ilex (this was Force Q).

0232 hours, the submarine came in sight and HMS Euryalus opened fire with star shells at a range of 5,800 yards, while the two destroyers were sent to the attack.

At 0335 hours, HMS Ilex obtained an ASDIC contact. Depth charging followed:

0338 hours: HMS Ilex (5 DCs set at 100 feet).
0343 hours: HMS Ilex (2 DCs at 150 and 300 feet)
0344 hours: HMS Echo (5 DCs at 150, 250 and 350 feet)
0354 hours: HMS Ilex (5 DCs at 150, 250 and 350 feet)
0431 hours: HMS Ilex (5 DCs at 150, 250 and 350 feet)
0440 hours: HMS Ilex (5 DCs at 350 and 550 feet)
0444 hours: HMS Echo (5? DCs at 350 and 550 feet)
0448 hours: HMS Ilex (5 DCs at 350 and 550 feet)
0455 hours: HMS Echo (5? DCs at 150, 250 and 350 feet)

The submarine suddenly surfaced. HMS Echo opened fire and scored a 4.7" hit abaft the conning tower with her second salvo. The destroyer then crossed ahead the submarine to deliver four depth charges set at 50 feet. The submarine rolled over and sank stern first. HMS Echo picked twenty survivors (five officers, including T.V. Scandola, and fifteen ratings). HMS Ilex picked up seven ratings. Twenty-one ratings were killed or missing.

Mario Spano12 Jun 1940050332.57 N, 26.05 E
At 0458 hours, Nereide was at periscope depth when a 12-15,000-ton tanker was sighted.

At 0503 hours, one torpedo (533mm, W 270 type) was fired from a bow tube at a range of 500 metres. It was claimed to have hit. The tanker escaped in low visibility.

This was the Norwegian tanker Orkanger (8,029 GRT, built 1928) proceeding to Alexandria (and shortly after sunk by Naiade). She had initially sailed from Port Said for Malta. At the Italian declaration of war, she was ordered to turn back.

(o) Tobruk harbour.During the evening, Nereide was at anchor in Tobruk harbour during an air raid. Her two machine guns fired 180 rounds of 13.2mm at two torpedo bombers who flew only 30 metres away. One of these was Swordfish E4H (lieutenant D.N. Collins, RN) of 813 Squadron from HMS Eagle, actually operating from Dekheila (an airfield just to the west of Alexandria)

At 2020 hours, the aircraft released its torpedo from 350-400 yards aimed at the submarine. Collins claimed that it hit its target and a column of 50-60 feet rose, but Nereide was missed. The Swordfish was hit by three machine gun rounds from the submarine and suffered only minor damage.

On 4th September 1940, Collins, flying the same Swordfish, was shot down by an Italian CR. 42 fighter while attacking the Maritza airfield (Rhodes). The crew of three survived to become PoWs.
Mario Spano13 Sep 19402215(o) South of Cape Littimos.At 2215 hours, three enemy destroyers were sighted at 4,000 metres. Nereide dived to attack but could not get into a favourable position.
Mario Spano17 Sep 19400536-1906(o) 43 miles south of Cape Gaudo.Between 0536 and 1906 hours, Nereide was the subject of an A/S search and heard many explosions without suffering any damage.
Augusto Migliorini12 Jul 19410325(o) Off Nikaria.At 0325 hours, the Italian steamer Apuania, towing a MAS boat, was sighted steering 110°.

(o) 230° - Cape Papas (Nikaria) - 8 miles
At 0053 hours, Nereide was cruising on the surface when a submarine was sighted at 6,000 metres.

At 0107 hours, she had closed to 700 metres, to fire two torpedoes from bow tubes at 3-second intervals. The second torpedo broke surface and disappeared. Immediately upon firing, the submarine turned to starboard to bring to bear her deck gun and opened fire with her machine guns. Shortly after, a column of water rose next to the enemy's conning tower and, as the submarine was disappearing, the deck gun scored a hit on the conning tower at less than 200 metres. T.V. Migliorini believed he had sunk the submarine and searched for survivors, but found none.

The submarine was HMS Tetrarch (Lieutenant Commander G.H. Greenway, RN). The confusion had not been one-sided, she was believed to have been attacked by two E-boats (MAS) and crash-dived. Two faint explosions had been heard and thought to be torpedoes hitting the sea bed. She was undamaged.

Augusto Migliorini10 Apr 19420110(o) North of Nicaria.At 0110 hours, a hospital ship was sighted steering 220°.
Augusto Migliorini10 Apr 19421454(o) North of Nicaria.At 1454 hours, fishing vessel no. 1519 R (most likely Greek) was stopped and her papers examined.
Augusto Migliorini13 Apr 19421305At 1305 hours, a vessel was sighted steering 030°. She was too far to be intercepted.

At 1930 hours, a submarine's periscope was sighted and shortly after she surfaced. Nereide gained a favourable position and also surfaced. She made a recognition signal but the other submarine dived and C.C. Terra thought she was German.

This was actually the submarine HMS Porpoise (Lieutenant L.A.W. Bennington, RN) on passage from Malta to Alexandria. At 2050C hours, she sighted Nereide steering 090° and believed it was a German U-boat. She passed a warning to Captain S. One, in Alexandria. It was repeated to HMS Urge, who was expected to be astern of her some 50 miles to the west. HMS Urge had actually been mined off Malta.
Pasquale Terra10 May 1942195634.04 N, 23.12 E
At 1956 hours, a submarine, believed to be German, was sighted at a distance of 1,200 metres. As a precaution, Nereide dived immediately.
Pasquale Terra9 Jul 1942210035.38 N, 35.26 E
At 2100 hours, a submarine was sighted. Nereide took avoiding action. This may have been Ondina who was lost two days later.
Pasquale Terra11 Jul 19421515-1550From 1515 to 1550 hours, several explosions were heard very close. Nereide was submerged at the time. When she came to periscope depth, nothing was in sight. C.C. Terra believed he may have been bombed by an aircraft.
Pasquale Terra13 Jul 19420107(o) Off Ras El Khanzir.At 0107 hours, information was received that two steamers had left Alexandretta for Port Said. Nereide altered course to intercept north of Ras El Khanzir. Nothing was sighted or heard.
Pasquale Terra30 Sep 1942225533.10 N, 26.54 E
At 2255 hours, several flares were dropped by aircraft. Nereide dived.
Pasquale Terra2 Oct 1942030033.00 N, 27.00 E
(o) Approximately.
At 0300 hours, an aircraft was sighted at close range. Nereide crash-dived and surfaced again at 0334 hours.
Renato Scandola29 Jun 19430639(o) Near Cape Dell'Armi.At 0639 hours, an aircraft was seen and the submarine dived.
Renato Scandola29 Jun 19430827(o) Near Cape Dell'Armi.At 0827 hours, an aircraft was seen and the submarine dived.
Renato Scandola30 Jun 19431805At 1805 hours, an aircraft was seen and the submarine dived.
Renato Scandola1 Jul 19430450(o) Near Naples.At 0450 hours, in foggy weather, a submarine was sighted. As T.V. Scandola had not been informed of Italian submarines in the area, Nereide was prepared for action. Torpedoes and the deck gun were ready to fire when the submarine appeared to be Italian.

At 0459 hours, visual signals were exchanged and were also answered by a second submarine who was following. These were probably Nichelio and Wolframio who had sailed from Pozzuoli for Portoferraio.
Renato Scandola12 Jul 1943174637.30 N, 15.10 E
(o) Approximate position. Near Catania.
This attack lacks details as Nereide did not return from this patrol.

At 1746 hours, a squadron of ten destroyers was sighted and three torpedoes (533mm, G7e type) were fired from bow tubes at 4,500 metres. Two destroyers were claimed to have been hit. These were probably units from the 5th Destroyer Flotilla.

At 0220 hours, Nereide was cruising on the surface when she was detected at a range of 10,200 yards by the radar of the light cruiser HMS Euryalus and, almost simultaneously, by the radar of the light cruier HMS Cleopatra. The warships were proceeding in company with the destroyers HMS Echo and HMS Ilex (this was Force Q).

0232 hours, the submarine came in sight and HMS Euryalus opened fire with star shells at a range of 5,800 yards, while the two destroyers were sent to the attack.

At 0335 hours, HMS Ilex obtained an ASDIC contact. Depth charging followed:

0338 hours: HMS Ilex (5 DCs set at 100 feet).
0343 hours: HMS Ilex (2 DCs at 150 and 300 feet)
0344 hours: HMS Echo (5 DCs at 150, 250 and 350 feet)
0354 hours: HMS Ilex (5 DCs at 150, 250 and 350 feet)
0431 hours: HMS Ilex (5 DCs at 150, 250 and 350 feet)
0440 hours: HMS Ilex (5 DCs at 350 and 550 feet)
0444 hours: HMS Echo (5? DCs at 350 and 550 feet)
0448 hours: HMS Ilex (5 DCs at 350 and 550 feet)
0455 hours: HMS Echo (5? DCs at 150, 250 and 350 feet)

The submarine suddenly surfaced. HMS Echo opened fire and scored a 4.7" hit abaft the conning tower with her second salvo. The destroyer then crossed ahead the submarine to deliver four depth charges set at 50 feet. The submarine rolled over and sank stern first. HMS Echo picked twenty survivors (five officers, including T.V. Scandola, and fifteen ratings). HMS Ilex picked up seven ratings. Twenty-one ratings were killed or missing.
