(0) 140° - Europa Point - 12 miles.
|At 0300 hours, as Nani was on the way home, a shadow was sighted ahead. It turned out to be a larger destroyer or sloop. Five minutes later, two torpedoes (533mm, W-G type) were fired from the bow tubes at a range of 1,200 metres, They both had an erratic course and missed.|

|4 Oct 1940||0046||36° 02'N, 4° 34'W||At 0036 hours, Nani sighted a shadow straight ahead at 2,500 metres. The submarine closed and realised it was a steamer navigating without lights, steering 130°. At 0045 hours, a destroyer was observed bearing 045° at 1,500 metres. A minute later, a torpedo (533 mm, W type) was fired from a bow tube at the steamer from a distance of 1,700 metres. It missed.|
|4 Oct 1940||0440|
(0) 312° - Point Europe - 7.5 miles.
|At 0440 hours, a destroyer was suddenly sighted at 400 metres, Nani dived immediately. C.C. Polizzi decided to resume his passage at a depth of 70 metres at 3 knots. At 1520 hours, the sounding gear broke down and the submarine now proceeded at a depth of 90 metres. At 1950 hours, Nani suddenly took a downward angle and stabilised only at 140 metres. The submarine finally surfaced at 2035 hours.|

|At 0413 hours, in very poor visibility, a dark shadow was sighted at 1,000 metres. Nani closed to 400 metres but realised that she was in an awkward position for a bow attack. She turned to port and at 0416 hours, the vessel opened fire on the submarine, letting off two rounds within 30 seconds, one at 400 metres and the other at 600 metres but without scoring a hit.|
Within a minute, Nani fired a torpedo (450mm, W 200) from a stern tube at 600 metres and, 36 seconds later, it hit the target which began to sink. The submarine moved to the limit of visibility, returning to observe lifeboats picking up survivors before moving away. C.C. Polizzi believed he had sunk a 7,000-ton tanker. The victim was in fact the armed trawler HMT Kingston Sapphire (356 tons). Of the crew of forty, three were killed, four officers and twenty-five ratings were picked up by the Spanish fishing vessel Nettuno and landed at Huelva. They were released on 30th October.
|22 Oct 1940||1538|
(0) NW of Madeira.
|At 1538 hours, the Greek steamer Souliotis (4,300 GRT, built 1917) was stopped by Nani and examined. She was on her way to New York, with a cargo of tobacco, wine and fish and was released. This was lucky for the Greek ship as six days later Italy declared war on Greece.|
|27 Oct 1940||1412-1550||37° 20'N, 24° 15'W||At 1335 hours, Nani sighted a ship on the horizon. It proved to be the Swedish Swedish Meggie (1,583 GRT, built 1889, Captain F.B. Johansson) detached from convoy OB.228. She was carrying 4,000 tons of coal from the UK to Madeira. At 1412 hours, she was ordered to stop and her papers examined. The crew of twenty-one was ordered to abandon ship and boarded the two lifeboats available. After sinking the ship with 8 rounds, Polizzi who had a good heart, decided to tow them for 12 hours toward the Island of San Miguel. They all reached the Azores safely.|
|5.||Nani (NI, I.21)||13 Dec 1940||Bordeaux||17 Dec 1940||1630||Pauillac||Sailed for patrol but turned back when an officer and a rating were hurt because of the bad weather. They were landed at Pauillac, with two more officers who also needed medical attendance. The four men were replaced before the submarine sailed again. Escorted in by the German minesweeper M 2.|
|6.||Nani (NI, I.21)||17 Dec 1940||Pauillac||18 Dec 1940||Pauillac||While at Pauillac, Nani shot down an enemy aircraft. There was an Egyptian report on 8th January 1941, that Italian submarines had been damaged in Brest by RAF attacks, but this was not confirmed. Italian submarines never used Brest and the report may have erroneously referred to this attack.|
|18 Dec 1940||0400|
(0) At Pauillac.
|At 0400 hours, Nani was anchored at Pauillac, awaiting orders to proceed for an Atlantic patrol (which was to be her last), when Bordeaux came under air attack by six Beauforts of 217 Squadron. The submarine observed an aircraft flying low northward, apparently returning from the raid. Fire was opened with her four machine guns and the aircraft appeared to be hit and believed shot down. Later, the Germans claimed to have found the wreckage of an enemy aircraft in the Gironde estuary. Yet, the only aircraft which failed to return from the mission was Beaufort 'G' (L4463) piloted by Sergeant D.A.G. Matthews and it actually crashed near Vannes. There is insufficient evidence to confirm that the aircraft was shot down by Nani.|
|7.||Nani (NI, I.21)||20 Dec 1940||1800, 1655 (GE)||Le Verdon||7 Jan 1941||Date?||Sunk with all hands||Sailed escorted out by the German minesweepers M-2 and M-13 and Sperrbrecher III, through 49°00'N, 19°00'W, maintaining a speed of 11 knots until 12°00'W and then northward for Atlantic patrol between 54°00'N and 55°00'N and 17°00'W and 20°00'W. Her departure was delayed due to an intensive A/S search (undoubtedly caused by the sinking of Tarantini). On 29th December 1940, she was advised that her northern limit was the parallel of Point Z (56°00'N). Her last communication was on 3rd January. She did not answer a request to state her position on 7th January. She was reported in German Grid AL 67 (ca. 54°09'N, 19°45'W) as of 1st January 1941 and AL 02 (ca. 56°51'N, 20°12'W) on 16th January 1941. She should have returned on 20th January 1941. Claimed sunk by corvette HMS Anemone (she had left convoy OB.269 and was joining convoy HX.99) but her position was some 300 miles to the North of Nani's area. She was lost with all hands, seven officers and forty-nine ratings perished.|

(e) 54° 16'N, 14° 15'W
|The U-boat (Bagnolini) reported earlier by an aircraft was hunted through the night by HMS Scimitar, HMS Skate, HMS Bluebell, HMS Westcott and HMS Candytuft and a Whitley aircraft. Skate got a contact and attacked at 1207 hours, but then lost it. Bagnolini did not report depth charges dropped at that time. Could this have been Nani? We will never be sure.|
|5 Jan 1941|
(e) 55° 29'N, 8° 33'W
|At 1525 hours, Sunderland 'A' (L5798) of 210 Squadron piloted by Flight Lieutenant R.E.G. Van der Kiste sighted what appeared to be the wash of a periscope at a distance of 1/2 mile. Within 45 seconds, an attack was made from a height of only 20 feet with two 450 lb depth-charges set to explode at a depth of 100 feet. No result was observed. The bottom of the hull of the Sunderland was damaged by suspected splinters from the explosions and on alighting at Bowmore, the aircraft rapidly filled with water. Only after heavy pumping and baling was a diver able to apply a leak stopper from the outside.|
Could this have been Nani? She was operating much farther west but one cannot rule out that she could have been withdrawing after developing mechanical defects or other type of damage (see also incident with Glauco).

(e) 60° 12'N, 15° 27'W
|At 1115 hours, the corvette HMS Anemone was proceeding steering 290°, to join convoy HX.99, when a U-boat was sighted at 3,200 yards. She opened fire at 3,200 yds and claimed a direct hit with the sixth round. The submarine submerged and was depth-charged, the last attack occurring at 1522 hours. She was claimed to have been sunk. The corvette HMS La Malouine took over the search at 1820 hours, but did not find anything. Some sources have attributed the sinking of Nani to this attack, but this is doubtful as she was operating much farther south. However, Captain D (Londonderry) believed that the position recorded by HMS Anemone was grossly in error and was actually 59°20'N, 13°20'W. Still this position was much farther north of Nani's assigned area.|
