  4 Jul 19401430
(0) About 60 miles east of Gibraltar.
At 1430 hours, following several hydrophone noises, Emo came to periscope depth and sighted a naval force consisting of battleships, an aircraft carrier and a number of destroyers on a westerly course. These were certainly Force H with the battle cruiser HMS Hood, the battleships HMS Valiant and HMS Resolution, the aircraft carrier HMS Ark Royal, the light cruisers HMS Enterprise and HMS Arethusa, and eleven destroyers (HMS Faulknor (D.8), HMS Fearless, HMS Forester, HMS Foresight, HMS Escort, HMS Foxhound, HMS Keppel (D.13), HMS Vortigern, HMS Vidette, HMS Active and HMS Wrestler) returning from Operation CATAPULT.
  6 Jul 19401450
(0) About 75 miles east of Gibraltar.
At 1450 hours, Emo observed a British squadron consisting of two battleships (one of them recognised as HMS Hood), one aircraft carrier and five destroyers at a distance of 12-13,000 metres. They had first been detected by hydrophones. The submarine could not close to less than 9,000 metres. At 1450 hours, following several hydrophone noises, Emo came to periscope depth and sighted a naval force consisting of battleships, an aircraft carrier and a number of destroyers on a westerly course.

These were certainly Force H with the battle cruiser HMS Hood, the battleship HMS Valiant, the aircraft carrier HMS Ark Royal, the light cruisers HMS Enterprise and HMS Arethusa, and the destroyers (HMS Faulknor (D.8), HMS Fearless, HMS Forester, HMS Escort, HMS Foxhound, HMS Wishart, HMS Vortigern, HMS Vidette, HMS Active and HMS Wrestler) carrying Operation LEVER.

2.Emo (EO, I.17)27 Aug 19400915Naples3 Oct 19401530Bordeaux4450Passage to Bordeaux. Patrolled between 42°00'N and 19°00'W and 30°10'W. Passed Gibraltar on 9th September 1940. Escorted in by the German minesweeper M-10 and Sperrbrecher V.
  14 Sep 19400900
0700 GMT (e)

(e) 41° 27'N, 21° 50'W
At 0830 hours (dawn), a steamer was sighted at 6,000 metres on a northerly course. Emo submerged and closed to the attack. At 0900 hours, the submarine fired a torpedo (533mm, S.I.) at a distance of 4,000 metres. It hit. This was the British St. Agnes (5,191 GRT, built 1918) carrying 7,500 tons of oil seed and general cargo [also reported — in error — as AGRUS], from convoy SLS.46 (Freetown to Methil). She was damaged and made an SOS. Emo trailed her and was close enough to identify her as St. Agnes and observe that she was armed with a 120mm or 152mm gun and a smalller one.

At 1730 hours, the submarine surfaced and opened fire. At 1749 hours, fire was checked after 28 rounds (which caused no visible damage as most failed to detonate) as a second freighter appeared on the scene. Chief Officer C.S. Whitticombe reported that the submarine surfaced twice firing 12 rounds the first time and another 8 rounds the second time. None appeared to hit.

Emo altered course to deal with the newcomer but, at 1830 hours, she was identified as the American Excalibur, and the submarine returned to the first ship.

At 1932 hours, a second torpedo (450mm) was fired from a stern tube. St. Agnes was hit and sank. Her sixty-four (or sixty-three?) survivors were picked up by the American steamer Exochorda (not Excalibur as reported in some documents) and landed in Lisbon.

3.Emo (EO, I.17)31 Oct 19400700Bordeaux6 Nov 19401130Bordeaux1052,5Sailed with Faà di Bruno, escorted out by the German minesweepers M-9 and M-21, for Atlantic patrol between 55°20'N and 56°00'N, and between 15°00'W and 20°00'W (Grids 9990-9998 and 9915). She was ordered to leave the Gironde estuary at a speed of 11 knots through 45°06'N, 02°32'W and 49°00'N, 19°00'W, reducing to 8 knots when passing the 12° W meridian, then course north to join her patrol position. Turned back because her commanding officer was injured.
  2 Nov 1940160047° 55'N, 10° 00'WAt 1600 hours, in heavy weather, the lookout Giuseppe Gobbi was carried away by a wave. Emo turned back to try to recover him but he was never found. Another lookout, Teodoro Caruso, was injured.
  3 Nov 1940070047° 55'N, 10° 00'WAt 0700 hours, a large wave fell over the conning tower and C.C. Carlo Liannazza was thrown heavily against the railing. He was injured apparently with a broken rib. The Executive Officer, T.V. Giuseppe Franco, took over and decided to turn back.

  19 Oct 1941032532° 20'N, 25° 23'EAt 0325 hours, Ammiraglio Cagni had just sailed from Bardia and was on her way to Taranto, when a dark shadow was sighted on the port beam. The submarine was just turning toward it when a gunfire shot was heard followed by a second. Cagni quickly dived as a third shot was heard.

This was HMS Kandahar , one of three destroyers (the others were HMS Griffin and HMS Jaguar) screening the minelayer HMS Abdiel. They were carrying troop reinforcements to Tobruk (operation CULTIVATE). Because of the urgency to reach their destination before daylight, the destroyers did not try to hunt the submarine.

36° 20'N, 19° 40'EAt 1045 hours, an enemy bomber was sighted and attacked, dropping four bombs. Cagni replied with her machine guns and the aircraft returned for three strafing runs.

This was Blenheim 'F' (No.6423, aircraft K7TF) of 203 Squadron piloted by Pilot Officer Hemsted belong to 201 Naval Cooperation Group. He had sighted a submarine steering 300° at 10 knots and dropped from 1500 to 800 feet to carry out the attack. Four 250-lb A/S bombs were released and they all overshot, the nearest being 60 yards off the submarine who took no action. The bomber carried out a strafing run as the submarine took evasive action. She remained on the surface and was shadowed for over an hour before the Blenheim departed. The submarine was described as 200-250 feet in length, coloured grey, with one gun forward and one aft, tall oval shaped conning tower, sharp bows and a short mast on the stern.

This was longest mission of an Italian submarine during WWII (137 days, 17,403 miles).
  17 Oct 1942112033° 00'N, 14° 00'WAt 1120 hours, a smoke was sighted on the horizon. Cagni maneuvered to take a position ahead of the vessel and dived at 1305 hours.

At 1412 hours, the submarine closed to a distance of 1,000 meters before recognising her to be Spanish Rio Francoli (2,078 GRT, built 1909 and aborted the attack.

2° 35'S, 18° 31'WAt 1130 hours, two masts were sighted on the horizon. Cagni proceeded at 15 knots to take a position ahead of the vessel.

At 1703 hours, the submarine submerged for the attack.

At 1842 hours, three bow torpedoes (450mm, W 200 type) were fired from 400 metres. All three hit and she sank.

This was the British Dagomba (3,845 GRT, built 1928) on passage from Takoradi to Trinidad.

Ten killed, twenty-one survivors were rescued by the Portuguese sloop Bartolomeu Dias at 0530 hours on 14th November in 07°05' N, 16°00' W. Twenty-three survivors in a lifeboat were picked up by a Vichy patrol vessel and landed at Dakar. They were interned for a few days before being liberated when the Allies landed in North Africa on 8th November.
  9 Nov 194211035° 28'S, 11° 52'WAt 1103 hours, a twin-engine plane was sighted at 5,000 metres. Cagni dived immediately.

34° 45'S, 17° 42'EAt 1503 hours, a smoke was sighted on the horizon steering 030°. Cagni proceeded to intercept at 15 knots. She could not catch up for an attack in daylight hours so C.C. Liannazza opted for an attack after dark.

At 1915 hours, the attack began but was thwarted by a sudden change of course of the vessel. She was now steering 070°.

At 2025 hours, a pair of torpedoes (450mm, 40 knots) were fired from bow tubes at a distance of 2,500 metres. They missed, apparently due to an irregular course.

This was the Greek steamer Argo (1,995 GRT, built 1920) on a voyage from Buenos Aires to Capetown and Durban.

At 2125 hours, another pair of torpedoes (450mm) were fired from bow tubes. They both hit and the vessel sank. Eighteen were killed [twelve crew members and all six passengers], seven survivors (including Captain Synodinos) were rescued by HMS Rotherham and another eleven by HMAS Norman. HMAS Norman later transferred the survivors she had picked up to HMS Rotherham which landed them at Simonstown in the evening.
  3 Jan 194313051° 35'S, 24° 25'WAt 1305 hours, the submarine Enrico Tazolli was met. Cagni was to cede her eight 450mm torpedoes but the bad weather prevented the operation from being carried out and it was finally cancelled.

(0) German Grid FD 3465.
The German Milk cow submarine U-459 (KK Wilamowitz-Möllendorf) was met and from 1530 to 1620 hours she supplied the Italian submarine with 41 tons of fuel (50 cbm).

An ULTRA intercept had revealed that Cagni was to meet U-459 on 1200 hours on 12th January in 01°03' N, 23°57' W.
  25 Jan 194300453° 22'N, 28° 10'WAt 0045 hours, a fully illuminated steamer was sighted steering 025°. It was believed to be the pre-announced Swiss Eiger (4,386 GRT, built 1929) on a voyage from Bahia to Las Palmas (Canaries).
  7 Feb 1943143229° 10'N, 23° 20'WAt 1432 hours, a German submarine was sighted on a southerly course. Recognition signals were exchanged.
  7 Feb 1943163729° 25'N, 23° 16'WAt 1637 hours, a German submarine was sighted on a northerly course. Recognition signals were exchanged.
  15 Feb 1943175044° 37'N, 9° 56'WAt 1750 hours, a Sunderland aircraft was sighted at 8,000 metres. C.C. Liannazza gave the order to crash dive, but for reasons not revealed, it failed and the submarine surfaced again. The aircrat circled then carried out an attack dropping six medium-sized bombs. They missed the submarine by 20-30 metres. Cagni was also strafed and had one rating killed and one wounded.

This was Sunderland was 'I' (DV961) of 461 Squadron (RAAF) piloted by Flight Lieutenant S.R.C. Wood. He sighted the submarine at a distance of 7 miles, steering 100° and correctly identified it as Italian. It dived from the clouds when it was 2-3 miles away. The submarine was observed to fire a red star cartridge and remained surfaced. Heavy strafing observed to knock men overboard. In an attack from the starboard beam six depth charges were released from 100-150 feet. Owing to a faulty distributor they were released in salvo and overshot. The Sunderland attacked at 44.49 N 09.17 W.

The submarine was covered in spray but was apparently undamaged and submerged two minutes after the attack.
  17 Feb 1943201544° 39'N, 10° 03'WAt 2015 hours, an aircraft was seen and the submarine dived.
