Giuseppe Finzi was informed by BETASOM that a convoy had sailed from Gibraltar.She was ordered to intercept it in 33°55' N, 09°15' W at 2000 hours on the 10th. The submarine altered course at 12 knots, but later engine defects slowed her down and were repaired. At 1735 hours on the 10th, Finzi received another order to proceed to 36°45' N, 10°15' W, the convoy was in 36°25' N, 08°25' W at 1500 hours on the 10th. A signal from BETASOM, received at 2330 hours on the 10th, ordered her to 36°15' N, 11°15' W. This location was reached at 0715 hours on the 11th with several more signals following until 12th August.

The enemy convoy was sighted at a distance of 8,000 metres. The submarine was forced to submerge at 1645 hours as one of the escorting destroyers turned toward her. At 2045 hours, she surfaced and tried to catch up with the convoy. At 2235 hours on the 12th, a signal was received from BETASOM reporting the convoy in 38°55' N, 13°25' W and ordering Finzi, Marconi and Veniero to attack it, but Finzi sighted nothing.
  13 Aug 1941023039° 11'N, 14° 02'WAn enemy destroyer was sighted at a distance of 3,000 metres and the submarine maneuvered to gain a more favourable position.

4.Giuseppe Finzi (FZ, I.2)5 Dec 19411748Le Verdon26 Dec 19411149St. Nazaire5273Sailed on a mission to rescue the survivors from the German raider Atlantis and her supply ship Python, northwest of Cape Verde (took 70 men from U-129). Four submarines participated in the operation: Finzi, Calvi, Torelli and Tazzoli. The four commanders were decorated by Admiral Doenitz.
  11 Dec 1941082535° 27'N, 18° 25'WAn unknown illuminated steamer was sighted steering 000°-020°. She was probably neutral and C.C. Giudice did not attempt to investigate as his submarine was on a rescue mission.
  16 Dec 19411315-154014° 30'N, 28° 30'WGiuseppe Finzi met with U-129 (KL Nicolai Claussen) carrying survivors from Atlantis and Python and took off seventy survivors and brought them to St. Nazaire.

5.Giuseppe Finzi (FZ, I.2)5 Feb 19420950Bordeaux31 Mar 19421759Le Verdon8286Patrolled in Caribbean, carried nineteen torpedoes. On 2nd February, BETASOM had issued an order to bombard Atlantic City (New Jersey) but three days later the order was countermanded by Admiral Legnani who warned them not to entertain similar ideas.
  10 Feb 1942120540° 43'N, 14° 11'WGiuseppe Finzi sighted two destroyers at a distance of 10,000 metres proceeding on a NW course. One of them turned toward the submarine and the submarine dived. Only two depth-charges were heard, one at 1235 hours and the other at 1247 hours but the destroyer remained in the area for several hours. Apparently she was keeping down the submarine as a convoy was heard at 1700 hours in 40°43' N, 14°18' W. The submarine finally surfaced at 1910 hours.
  3 Mar 1942133022° 06'N, 62° 54'WAn unknown aircraft was sighted at 15,000 metres and the submarine dived.
  4 Mar 1942202223° 40'N, 62° 22'WAn unidentified tanker was sighted at 10,000 metres steering 160°. The submarine maneuvered to carry out a night attack, but engine defects delayed her and she could not renew contact.
  5 Mar 1942113824° 11'N, 61° 33'WAn illuminated steamer was sighted on a SE course at a distance of 8,000 metres. The submarine gave up the chase as she appeared to be neutral.

At 2055 hours on 5th March 1942, a smoke was sighted on the horizon at a range of 10,000 meters in 24°00' N, 61°42' W. It turned out to be a tanker steering 265°.

At 0308 hours on the 6th, Giuseppe Finzi closed to 1,200 metres and , she fired a pair of torpedoes (533mm) from her bow tubes. One torpedo apparently hit amidship and another hit the stern. However, survivors later reported that only one torpedo hit under the bridge.

This was the British Melpomene (ex-French, 7,011 GRT, built 1923) bound from Belfast to New Orleans in convoy O.S.19. The crew began to abandon ship.

At 0337 hours, the submarine fired a third torpedo from a bow tube at Melpomene and hit her again, but she failed to sink.

At 0402 hours, a fourth torpedo was fired and squarely hit Melpomene which finally sank at 0423 hours. The forty-nine men of her crew had taken to three lifeboats and made for San Juan (Puerto Rico). They were all rescued (including three seriously wounded) by the American steamer Idaho.

At 1435 hours on 6th March 1942, Giudice sighted a vessel from a distance of 8,000 metres and trailed her with the intention of attacking after dusk.

The attack finally occurred at 0150 hours on the 7th, Giuseppe Finzi firing two bow torpedoes (533mm) and both hit. This was the Swedish Skåne (4528 GRT, built 1921) steering 163° at 9 knots [also reported as Boren, ex Skåne]. She was on a trip from New York to Bombay, carrying 7,500 tons of general cargo and some trucks and armoured cars on deck. The vessel was only damaged and Captain Cronberg and his crew began to abandon ship.

At 0254 hours, a third torpedo was fired and again hit the Swedish Skåne. She was sinking very slowly and the submarine fired 7 rounds to finish her off.

At 0502 hours, gunfire was resumed with another 18 rounds, pumped into her hull rendering the ship in a sinking condition. At 0620 hours, the submarine was forced to dive because of an aircraft with lights on (which was probably a commercial one). An explosion was heard at 0700 hours and Skåne must have sunk at this time. The crew of thirty-four (including two women) had taken to two lifeboats and were all picked up the next day by the American freighter Ipswich. The survivors believed that they had been attacked by two submarines, one of them of the PIETRO MICCA type, the confusion certainly arose from Finzi carrying attacks from both sides. It was suspected that the vessel may have been boarded by the Italian submarine (this was not the case) but the American authorities were relieved to note that no US Navy codes were carried.

On 8th March, between 1130 and 1700 hours, the submarine reloaded her forward tubes with three torpedoes which were carried on deck.
  8 Mar 1942173022° 42'N, 60° 07'WThe submarine was instructed by BETASOM to cede 50 tons of fuel to Morosini. GIUDICE replied that this would significantly curtail the autonomy of Giuseppe Finzi and BETASOM instructed him to cede only 30 tons.

(e) 23° 33'N, 60° 10'W
At 2349 hours on 9th March 1942, Giuseppe Finzi sighted a vessel at a range of 10,000 metres in 23°49' N, 59°58' W. It appeared to be a tanker steering 250° at 10-11 knots. She was the Norwegian motor tanker Charles Racine (9,957 GRT, built 1937) and she was actually steering 245° at 12 knots.

At 0124 hours on 10th March, two bow torpedoes (probably 533mm) were fired at 1,300 metres and claimed one hit. In fact, none had hit and her survivors later reported that one torpedo had missed 10 metres ahead. Guidice noted that the tanker did not make an SOS.

At 0511 hours, another pair of torpedoes were fired from the bow tubes at a distance of 1,500 metres. This time both hit, one amidships and the other the stern section. The ship made an SOS and was abandoned.

At 0540 hours, a third pair of torpedoes were fired and again both hit, but the ship still refused to sink. At 0719 hours, one torpedo was fired from a stern tube and hit the tanker Charles Racine who finally sank. Her crew of forty-one were all saved. They had been sighted by a plane and then by the destroyer USS Moffett (DD-362), who found three boats with thirty-four survivors and brought them to San Juan. The remaining seven men in the fourth lifeboat were picked up by an Argentine steamer and landed in Trinidad.
  11 Mar 1942123023° 12'N, 56° 22'WThe Italian submarine Morosini was sighted and recognition signals were exchanged. However, at 1250 hours, Morosini sighted a ship in 23°12' N, 56°42' W steering 240° and Giuseppe Finzi turned away to let her carry out an attack.
  11 Mar 1942165523° 03'N, 56° 46'WAn unknown steamer was sighted on a 250° course. (possibly Manaqui?). Giuseppe Finzi closed to attack, but then sighted another ship at 1925 hours.
  11 Mar 1942192522° 35'N, 57° 25'WFinzi closed to attack but then sighted Morosini at 2010 and told her of the sightings.
  12 Mar 19420149A steamer had been sighted at dusk on 11th March and Giuseppe Finzi closed to attack. Giudice opted for a stern shot, as he only had one torpedo left in the bow tubes. However, he was beaten to the race by Morosini which torpedoed the steamer first. The target was probably Manaqui (2802 GRT, built 1921) who disappeared without a trace at that time.
  12 Mar 19421305Giuseppe Finzi closed Morosini to refuel her, as instructed by BETASOM. At 1516 hours, she took her in tow to start the refuelling process and eventually 24 tons were transferred. Finzi then returned home.
