		19 Oct 1941	0325	32° 20'N, 25° 23'E	At 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.

		24 Nov 1941	0805		At 0805 hours, a derelict mine was sighted at a distance of 150 metres. It was hit with rifle fire and sank. Twenty seconds later, it exploded, shaking the submarine. At 1410 hours, a second mine was sighted but the appearance of an aircraft prevented the submarine from disposing of it. At 1645 hours, a third mine was sunk without difficulty.

		30 Dec 1941	1045 1055 (e)	36° 20'N, 19° 40'E	At 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.

6	Liannazza, Carlo	6 Oct 1942	1830	La Maddalena	20 Feb 1943	1830	Bordeaux	17403	Patrolled off Capetown, in area between 01°00'N and 02°00'S, and between 27°00'W and 32°00'W, then headed to Bordeaux (passed Gibraltar on 12 October 1942). This was longest mission of an Italian submarine during WWII (137 days, 17,403 miles).
		17 Oct 1942	1120	33° 00'N, 14° 00'W	At 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.
		3 Nov 1942	1842 1800 GMT (e)	2° 35'S, 18° 31'W	At 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 1942	1103	5° 28'S, 11° 52'W	At 1103 hours, a twin-engine plane was sighted at 5,000 metres. Cagni dived immediately.
		29 Nov 1942	2025 2000 (e)	34° 45'S, 17° 42'E	At 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 1943	1305	1° 35'S, 24° 25'W	At 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.

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 1943	0045	3° 22'N, 28° 10'W	At 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 1943	1432	29° 10'N, 23° 20'W	At 1432 hours, a German submarine was sighted on a southerly course. Recognition signals were exchanged.
		7 Feb 1943	1637	29° 25'N, 23° 16'W	At 1637 hours, a German submarine was sighted on a northerly course. Recognition signals were exchanged.
		15 Feb 1943	1750	44° 37'N, 9° 56'W	At 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 1943	2015	44° 39'N, 10° 03'W	At 2015 hours, an aircraft was seen and the submarine dived.

Arrived in the Indian Ocean on 8th September 1943. First ordered to Colombo, but then diverted to Durban. She was met by the corvette HMS Jasmine and brought in and moored to the light cruiser HMS Caradoc.
		1 Jul 1943	0140		At 0140 hours, an aircraft was detected with Metox and the submarine dived.
		2 Jul 1943	0110	46° 00'N, 9° 00'W (0) Very approximate position.	At 0110 hours, an aircraft was detected by Metox and the submarine dived to 50 metres. Six bomb explosions were heard.
		2 Jul 1943	0955		At 0955 hours, fifteen aircraft were seen and the submarine dived.
		2 Jul 1943	1655		At 1655 hours, an aircraft was seen diving from the sun and the submarine dived.

		4 Jul 1943	1635		At 1635 hours, an aircraft was seen and the submarine dived.
		12 Jul 1943	1615	27° 34'N, 21° 15'W	At 1530 hours, a steamer was sighted steering a northerly course. Two minutes later, Cagni submerged and proceeded to attack at periscope depth. At 1615 hours, three torpedoes (450mm, one with standard and two with magnetic pistols) were fired from 1,500 metres. After about a minute, a muffled explosion was heard giving a running range of 1,300 metres. At 1620 hours, three depth charges were heard followed, at 1628 hours, by more. C.C. Roselli Lorenzini believed that the vessel had been hit by a torpedo with a magnetic pistol and the other explosions were perhaps torpedoes hitting the bottom.
		15 Jul 1943	1433	21° 00'N, 23° 00'W	At 1433 hours, two masts were sighted on the horizon at 12,000 metres. Cagni proceeded to intercept at 12 knots. At 1720 hours, the submarine submerged and prepared to launch two torpedoes from forward tubes. At 1834 hours, the vessel was recognised as Portuguese and the attack broken off.
		19 Jul 1943	0928	15° 20'N, 21° 05'W (0) Position at noon.	At 1128 hours, a vessel was sighted. One minute later, Cagni submerged to the attack. At 1300 hours, it was recognised as a Swish ship and the attack aborted.
		22 Jul 1943	0358	6° 52'N, 20° 45'W	At 1510 hours on 21st July, a smoke was sighted on the horizon. Cagni proceeded to intercept at 13 knots. At 1547 hours, she submerged for a stern attack with two torpedoes. The vessel appeared to be a 3,000-ton armed merchant cruiser with four medium-sized gun and six multiple machine gun mounts. At 1713 hours, the sudden loss of periscope depth prevented the attack from being carried out and contact was lost. At 1845 hours, the submarine surfaced and sighted the vessel again and trailed her for an attack after dark. At 0243 hours, on 22nd July, Cagni had gained a position ahead of her target and submerged. At 0358 hours, two torpedoes (450mm) were fired from bow tubes at a distance of over 2,000 metres. They missed. After 12 minutes, explosions were heard believed to be from depth charges. The submarine surfaced and sighted the vessel at 8,000 metres. An attempt to give chase was quickly given up as fuel consumption was becoming a problem.
		25 Jul 1943	0149 0100Z (e)	6° 40'N, 21° 00'W	At 0145 hours, the shadow of a warship was sighted at 2,000 metres. Initially, it was thought to be a destroyer steering 025° at 15 knots. Cagni turned to make a stern attack but she quickly passed at 600-800 metres before it could be made. At 0146 hours, the shadow of a large ship was observed proceeding on a parallel course to the destroyer. At 0149 hours, two torpedoes (450mm) were fired from bow tubes at a distance of 2,500 metres aimed at this target believed to be an aircraft carrier. As another destroyer was now sighted about 1,000 metres astern of the submarine, C.C. Roselli Lorenzini took her down to 110 metres. After 154 seconds, two explosions were heard followed by a louder one. At 0245 hours, Cagni surfaced but heavy rain had reduced visibility to the minimum and nothing could be seen. This was actually the armed merchant cruiser HMS Asturias (22,048 tons, built 1926), zigzagging at 9.7 knots. One torpedo was observed to miss ahead, the other hit amidship. The explosion was muffled. Her engine room, boiler room and auxiliary engine room were flooded, but she managed to crawl away steering 036° at 5 knots. The "aircraft-carrier" was actually a floating dock towed by the tugs Thames and Roode Zee proceeding in company. They had been screened by the corvettes HMS Clarkia, HMS Woodruff and HMS Cowslip, the sloop HMS Milford and the armed whaler HMS Southern Gem and the armed trawler HMS Inkpen. The floating dock, tugs and remaining escorts continued on their way. HMS Clarkia and HMS Southern Gem stood by the stricken vessel and were joined by the frigate HMS HMS Exe on 26th July, followed a few hours later by the sloop HMS Folkestone and the tug Zwarte Zee who took HMS Asturias in tow. On the following day, the frigate HMS Moyola brought pumps and other equipment. HMS Asturias arrived at Freetown at 0400Z hours on 1st August.
