  13 May 1941191653° 50'N, 21° 00'WAt 1745, a steamer was observed suddenly coming out of the mist at 10,000 metres. It apparently also sighted the submarine and reverted course. Morosini fired two rounds at over 10,000 metres, but they fell short by about 3,000 metres. The enemy vessel replied with ten rounds, the last round falling short by 2,000 metres. She sent an SOS identifying herself as the British Vancouver (5,729 GRT, built 1928) and escaped to the North.

At 1100 hours, Morosini had changed course following new instructions from BETASOM. At 1500 hours, a smoke was observed to the port side. The submarine tried to close but, at 1645 hours, the vessel made an SOS identifying herself as the British Manchester Port (5,569 GRT, built 1935) and turned tail. Morosini attempted to give chase, but could not close to less than 10,000 metres. At 2110 hours, the submarine was ordered by BETASOM to resume her course to rejoin the position assigned in the morning and abandoned the chase.
  15 May 1941100353° 30'N, 10° 25'WAt 1003 hours, Morosini received a signal from Bianchi that a convoy of three steamers, escorted by detroyers, had just been sighted at 0900 hours in Italian Grid 7626/12, course and speed unknown. She altered course to intercept. At 1339 hours, a new signal from Bianchi, made at 1315 hours, was deciphered and reported a convoy of 10-20 ships escorted by destroyers steering 240°, 8 knots in Italian Grid 5826/46. This was only 25 miles away from Morosini and she altered course again.

At 1850 hours, a large aircraft was observed flying toward the submarine from a distance of 10,000 metres. Morosini dived and, at 1854 hours, she had reached a depth of 50 metres when eight bombs exploded. At 1912 hours, the submarine was at a depth of 70 metres when another eight explosions occurred. C.C. Fraternale took his submarine to 90 metres and another eight depth charges exploded at 1930 hours.

The aircraft was Catalina 'Z' of 209 Squadron, piloted by Flight Lieutenant Spotswood. It had been sent to escort convoy OB.321 and had been informed that a U-boat was shadowing the convoy. Morosini had been sighted as she was 10 miles on the port beam of the convoy and closing fast. The aircraft made an approach from the sun and, as the submarine crash dived, dropped four depth charges about 40 yards across the bow, just 15 seconds after the submarine had disappeared. A large air and oil bubble was observed. The two corvettes HMS Rhododendron and HMS Hibiscus, escorting the convoy, were detached to hunt the submarine.
  17 May 1941134551° 00'N, 21° 18'WAt 1345 hours, the submarine Otaria was sighted at 3,000 metres. Recognition signals were exchanged.

  30 Jun 19411045At 1045 hours, BETASOM ordered the submarines to the following positions:

Torelli in Grid 2533/36 or 36°58' N, 12°30' W
Morosini in 2511/33 or 36°30' N, 13°20' W

Malaspina in 3972/51 or 33°00' N, 11°45' W.

At 2115 hours, Malaspina sighted Morosini and exchanged recognition signals.
  30 Jun 19412045At 2045 hours, the submarine Malaspina was sighted at 3,000 metres. Recognition signals were exchanged.
  5 Jul 19411214At 1214 hours, the submarine Cappellini was sighted. Recognition signals were exchanged.
  6 Jul 19411240At 1240 hours, a submarine armed with a single gun was sighted. It was probably a German U-boat. Morosini turned away.
  9 Jul 19412035At 2035 hours, a large aircraft was seen. Morosini made a recognition signal but this was not answered and it flew toward her. The submarine dived.

At 1607 hours, a smoke was sighted on the horizon. Morosini took an intercepting course with the intention of attacking after dark.

At 2345 hours, the submarine had closed on the surface to 800 metres and launched a torpedo (450mm) from a bow tube. The torpedo porpoised, breaking the surface twice, it turned to port and missed.

At 2356 hours, a second torpedo (533mm) was fired from a bow tube at a distance of 700 metres. After 32 seconds, it hit the stern section. The vessel made an SOS identifying herself as the British Rupert De Larrinaga (5,358 GRT, built 1930). She was from convoy OG.67d and was carrying coal from the Tyne to Las Palmas.

Rupert De Larrinaga was still afloat and, at 0059 hours, Morosini fired a third torpedo (533mm), this time from a stern tube. It hit after 23 seconds and the vessel sank at 0105 hours. All her crew of forty-four were rescued by the Spanish steamer Campeche (MARICOSOM reported it as the Spanish steamer Caceres but this was an error).

At 0344 hours, a smoke was sighted and Morosini moved to intercept.

At 0524 hours, she fired a single torpedo (533mm) from a bow tube at a range of 1,000 metres. The torpedo was believed to have hit forward after 45 seconds. Fraternale did not observe a column of water, but rather boiling bubbles next to the hull. In fact, the torpedo had missed. The target was the ocean boarding vessel HMS Lady Somers (8,194 GRT, built 1929).

A minute later, a second torpedo (450mm) left a bow tube and this time it did hit astern. The enemy vessel now opened fire on the submarine with two guns of about 120mm, one forward and one aft, forcing the submarine to submerge at 0530 hours. Fraternale observed that the vessel was still afloat but immobilised, and decided to renew the attack at daybreak. He had no torpedoes left in the forward tubes.
  15 Jul 1941083237° 10'N, 20° 42'WAs Morosini was getting ready to finish off HMS Lady Somers, a tanker appeared on the scene at 0832 hours. Fraternale maneuvered for a stern attack on the new arrival, but soon recognised it as Spanish and aborted.

This was the Spanish tanker Campeche (6382 GRT, built 1934) who was answering the SOS from Lady Somers.
At 1002 hours, a torpedo (533mm) had been loaded in a forward tube and it was fired from a short distance at Lady Somers. It hit after 15 seconds and she finally sank. The Spanish ship rescued her 138 survivors from a total of 175.
  17 Jul 19411216-1300At 1216 hours, a steamer was sighted and closed for a stern attack. This was the Portuguese Santa Irene (520 GRT, built 1921) flying the Swiss flag and the attack aborted. She would be sunk by the submarine HMS Taurus during the night of 12/13 April 1943.

3.Morosini (MS, I.20)6 Sep 19412135La Pallice27 Sep 19411340Bordeaux3130,15Patrolled off Gibraltar. At 1000 hours on 10th September, ordered to an area between 32°00'N and 33°00'N, and between 15°00'W and 16°00'W, and an area between 31°00'N and 32°00'N , and between 14°00'W and 15°00'W. Ordered on 11th September to 35°15'N, 09°05'W. At 1900 hours on the 18th, ordered to 35°00'N, 10°45'W thence to 35°55'N, 13°05'W. Interrupted patrol because of defects. Her hydrophones did not work properly, she had only detected her escorting Sperrbrecher from a distance of 2,000 metres.
  18 Sep 1941175035° 14'N, 9° 06'WAfter a careful hydrophone watch, Morosini came to periscope depth at 1750 hours and was surprised to see a destroyer proceeding at high speed at only 1,000 metres. It had not been detected. The submarine went deep very quickly but was not hunted.
  19 Sep 1941032035° 36'N, 10° 00'WAt 0320 hours, Morosini was proceeding on the surface when a small destroyer or submarine chaser was sighted and shortly after another two units of a similar type. The submarine stopped her diesels and was not detected.

At 0810 hours, Morosini, proceeding to intercept a convoy after having been informed the previous evening, finally made contact. The convoy was steering 270° at 7 knots. The submarine made an enemy report and kept the contact until 1320 hours, when forced down by a destroyer. At 2020 hours on the 20th, her attempts to renew contact with the convoy had come to nought. Morosini had developed mechanical defects and had to return home.
  19 Sep 1941230836° 18'N, 12° 37'WAt 2308 hours, a submarine chaser was sighted proceeding to the southeast.
  23 Sep 1941105043° 44'N, 13° 11'WAt 1050 hours, the submarine Perla was encountered and exchanged recognition signals.

4.Morosini (MS, I.20)18 Nov 19411740La Pallice20 Dec 19411540Bordeaux5786Patrolled northwest of Canaries, in concert with Cappellini and Da Vinci.
  29 Nov 1941204539° 40'N, 28° 31'WAt 1300 hours, Morosini had been informed by BETASOM (1215/29) of a convoy of twenty ships sighted at 0415 hours in Italian Grid 7137/56 on a southerly course and was proceeding to intercept. At 2045 hours, a destroyer was observed at a distance of 10,000 metres. The submarine dived to avoid being seen. Later, she resumed her course to encounter the convoy but sighted nothing.
  30 Nov 1941112039° 18'N, 27° 25'WAt 1120 hours, a German U-boat was observed at 10,000 metres. They closed to exchange information at vocal distance. The U-boat was also looking for a the convoy and had sighted nothing.
  3 Dec 19410555-112038° 36'N, 35° 42'WAt 0555 hours, Morosini sighted a light and closed the vessel to a distance of 200 metres, identfying her as Spanish. Fraternale decided to wait until daylight to investigate.

At 1120 hours, the submarine maneuvered ahead of the freighter and ordered her to stop for examination. This was the Spanish Vizcaya (4578 GRT, built 1938) proceeding from Havana to Bilbao and her master came on board with his papers. She was allowed to proceed.

At 1950 hours, Morosini sighted smokes on the horizon. She had located the convoy (this was OS.13), but could not close to less than 10,000 metres when she was detected by an escort vessel. Fraternale took his boat to a depth of 150 metres as depth charges exploded.

This was the sloop HMS Rochester who attacked with four patterns of depth charges, followed by the sloop HMS Leith who dropped a pattern of eight depth-charges. HMS Rochester could not regain contact, but water leaks forced the submarine to cut short her patrol.

6.Morosini (MS, I.20)11 Feb 19421525Bordeaux4 Apr 19421900Bordeaux9414Patrolled off Guadeloupe. Carried twelve torpedoes, including two A/115 450 mm and also W.200/450 mm, which gave problems. C.C. Fraternale thought that A/115 torpedoes should not be carried, especially since the submarine did not carry a full load and that A/115 were 30 years old and unreliable. Yet recently Capitano di Corvetta Da Giacomo of Torelli had preferred using A/115 torpedoes instead of W/200 which were loaded as he found them more accurate. NOTE: the submarine carried eight pairs of binoculars, all of the Zeiss type, but four suffered defects (apparently their lenses were detached internally).
  23 Feb 1942193029° 10'N, 28° 15'WAt 1930 hours, a merchant vessel was sighted on the starboard beam. Apparently, she also sighted the submarine and turned tail. She made an SOS and identified herself as Sagaing,but Fraternale could not find her in his copy of Weyer's Taschenbuch. The submarine gave chase at her maximum speed of 13 knots but could not get to a distance inferior of 1-12,000 metres and the vessel escaped. This was the British Sagaing (7958 GRT, built 1925).
  2 Mar 1942224021° 55'N, 47° 05'WAt 2240 hours, the submarine Leonardo Da Vinci was encountered. She was to cede some fuel to Morosini. Because of the heavy seas and the relative short hose (80 meters) the operation was difficult and the hose broke, a second hose also broke and the operation had to be cancelled.
  11 Mar 1942183823° 15'N, 56° 35'WAt 1153 hours, Morosini sighted the smoke and masts of a vessel in 23°15' N, 56°35' W. It turned out to be a tanker on a southerly course. Morosini gave chase. At 1245 hours, the submarine Finzi was encountered and informed about the tanker. At 1630 hours, Morosini appeared to be in a good position and submerged for the attack.

At 1838 hours, a pair of torpedoes (533mm, W 270 type) were launched from the bow tubes at a distance of 1,400 metres. Fraternale could not follow his torpedoes' wake as the submarine lost trim, but they missed. The tanker had apparently sighted the periscope and turned away, firing with her stern gun. The submarine went down to 20 metres. Morosini surfaced at 1950 hours. Half an hour later, Giuseppe Finzi came into sight and reported that the tanker was escaping to the south.
  12 Mar 1942013822° 45'N, 57° 40'WAt 2222 hours, a smoke was sighted in 22°45' N, 57°40' W steering 250°. Morosini trailed her with the intention of attacking after dusk. The target appeared to be a 7,000-ton merchant vessel, 130 metres in length.

At 0138 hours, the submarine closed to a range of 1,200 metres and fired a pair of torpedoes (450mm, W 200 type) from her stern tubes. The first torpedo made a turn to port and missed completely but the second one squarely hit the target. The vessel sank in four and half minutes.

Initially, Morosini was attributed the loss of the British Stangarth (5,966 GRT, built 1942) but she had sailed from New York on 11th March and could not have reached the Caribbean a day later. Stangarth was later attributed to U-504 (KK Hans-Georg Friedrich Poske). Morosini's victim was probably the British Manaqui (2,802 GRT, built 1921) who disappeared without a trace at that time. She had sailed from Cardiff for Kingston Jamaica and had joined convoy OS.20. She left the convoy on latitude 36°00' N (probably near longitude 22°06' W) and her maximum speed of 9-9.5 knots. To be in the position of Morosini's attack she would have maintained an average speed of 8.7 knots which was reasonable. Thirty-four crew members and six gunners perished.
  12 Mar 1942131023° 16'N, 56° 35'WAt 1310 hours, the submarine Finzi was encountered and, at 1445 hours, she took Morosini in tow to give her fuel. At 1555 hours, the towing cable broke but, fortunately, the 120-m long hose did not. By keeping her engines running at a slow speed, Morosini managed to get 20.9 tons of fuel by 2100 hours.

At 2005 hours, the masts of a tanker were observed on the port bow. She was steering 190° at about 12 knots. Morosini took an interception course. At 0503 hours, a pair of torpedoes (533mm, W 270 type) were fired from the bow tubes at 600 metres. After 25 seconds, two torpedoes were claimed to have simultaneously hit amidships; survivors would report only one hit on the port side amidship.

This was the Dutch tanker Oscilla (6341 GRT, built 1939) in ballast, on passage from Gourock to Curaçoa. She had a crew of nineteen Dutchmen, thirty-six Chinese and one Englishman. The ship was still afloat, fifty-two men abandoned ship in three lifeboats except for four men who were missing.

At 0520 hours, Morosini fired a torpedo (450mm, A 115 type) from a stern tube at a distance of 600 metres. It had a straight run but appeared to hit without detonating.

At 0523 hours, another torpedo (450mm, type A 115) was launched from a stern tube and appeared to have the same result.

At 0534 hours, a torpedo (533mm, W 270 type) followed from a distance of 700 metres. It broke surface twice but hit the target. Survivors confirmed that it hit amidship but this time on the port side, Nevertheless, Oscilla remained afloat.

At 0553 hours, Morosini opened fire with both 100mm guns. Although the tanker was armed, she did not have a gun crew on board. After 81 rounds were expended, the tanker finally capsized and sank. The survivors were picked up by the American steamer Explorer.

At 1743 hours, the masts of a tanker were discerned over the horizon. It was proceeding northward at about 12 knots. Morosini maneuvered to take a position ahead and submerged at 2038 hours. The submarine's attack periscope was defective and Fraternale had to use the observation periscope.

At 2214 hours, two torpedoes (450mm, W 200 type) were fired from the stern tubes at a distance of 1,000 metres. Both were claimed to have hit after 52 seconds, and this was confirmed by survivors. One hit forward of the bridge and the other forward of the engine room. It was the British tanker Peder Bogen (9741 GRT, built 1925), on passage from Trinidad to Halifax and ultimately for the UK. She was proceeding at 10.5 knots when she was torpedoed. The crew of fifty-two and one passenger abandoned ship in two lifeboats. However, they noticed after almost three hours that the ship was not sinking and decided to return to her.

However, from 0154 to 0203 hours, the submarine began shelling the tanker from about a mile. Her aim appeared to be poor but the firing was enough to discourage the crew from boarding her again. The tanker still refused to sink and gunfire was renewed from 0215 to 0228 hours and this time Peder Bogen disappeared beneath the waves. The submarine had expended 75 100mm rounds to sink her and had no more torpedoes.
