  18 Dec 19400515+54° 24'N, 19° 04'WAt 0515 hours, Veniero sighted a merchant vessel at 3,500 metres. When the range had closed to 800 metres, a torpedo (450mm) was fired from a bow tube. It missed astern. The target was the Greek steamer Anastassia (2,883 GRT, built 1905) from convoy SC.15d on passage from Halifax to Belfast.

At 0525 hours, Veniero had reverted course to make a stern shot (533mm) from a distance of 500 metres but and it hit amidship.

Shortly after, as Anastassia was settling very slowly, Veniero fired off three rounds, two of which hit to accelerate her sinking. In fact, she had not yet sunk as she would be found derelict on 20th December. Veniero later returned and picked up eight survivors although this was against her orders. Nineteen were killed or missing.

At 1115 hours, Veniero sighted an aircraft approaching. She could not make a recognition signal as the cartridge did not work. As a precaution, the submarine dived and had reached a depth of 20 metres when three explosions were heard. The attack had been made by Sunderland 'B' (N9049) of 10 Squadron (RAAF) piloted by Flying Officer V.A. Hodgkinson. It had been looking for a convoy to escort, when a half submerged U-boat was sighted at a distance of 3 miles.

The aircraft swooped down to a height of 100 feet and a stick of four depth charges was released after the U-boat had totally submerged. The first depth charge fell 100 yards in front of the swirl and along the estimated track. The remaining three fell along the track at 125 foot intervals. The Sunderland remained in the vicinity for an hour but no results to the attack were observed.

  8 Mar 1941133046° 00'N, 9° 50'WAt 1330 hours, an unidentified aircraft was seen and the submarine dived.
  9 Mar 19410220At 0220 hours, Veniero was informed of a convoy in 53°30' N, 14°30' W. The submarine altered course to 290° at 11 knots to intercept but was then ordered by BETASOM to resume her course to her patrol area.
  18 Mar 1941022054° 44'N, 19° 52'WAt 0220 hours, a drifter was observed at 8,000 metres. Veniero dived to avoid being seen.
  19 Mar 19411153At 1153 hours, Veniero was informed of a convoy of 25-30 ships in 55°05' N, 21°15' W. The submarine altered course to 105° at 11 knots to intercept, but again altered course as she received more signals reporting the convoy. However, at 2156 hours, she had to stop her engines due to defects but managed to effect some repairs and resume her course. By 2000 hours on the 20th, she still had not made contact.
  21 Mar 19411645At 1645 hours, an enemy destroyer was observed at periscope depth at a distance of 8,000 metres after the hydrophones had picked up sounds. Veniero remained submerged and heard several noises during the following hours and believed she was being hunted by two or three destroyers.
  23 Mar 1941143048° 12'N, 17° 20'WAt 1430 hours, Veniero was informed of a convoy in 50°35' N, 18°45' W, steering 235° at 7 knots. The submarine altered course to 280° at 10 knots to intercept.

At 1609 hours, a vessel was observed at a distance of 8,000 metres. It tried to escape.

At 1630 hours, Veniero opened fire. She stopped and was abandoned. This was the British steamer Agnete Maersk (2,104 GRT, built 1924), a straggler from convoy O.G.56.

Shortly after, Veniero fired two torpedoes at Agnete Maersk to finish her off. They missed under.

At 1650 hours, gunfire was resumed to try to finish off Agnete Maersk but she still did not sink.

At 1656 hours, a third torpedo was fired, but it also missed under.

At 1725 hours, gunfire was resumed again and this time Agnete Maersk was set afire and sank. Twenty-eight men were killed, there were no survivors.

6Petroni, Manlio20 May 19411410Bordeaux19 Jun 19411600Bordeaux5550,5Sailed for Atlantic patrol in approximate area 35°00'N, 11°00'W. On 2nd June, ordered to area between 33°00'N and the coast, and and between 08°00'W and 09°00'W. Escorted from Gironde buoy no.1 to le Verdon by Sperrbrecher III.
  25 May 1941125744° 30'N, 11° 00'WAt 1257 hours, an unknown submarine was sighted. Veniero prudently turned away.
  27 May 1941100038° 26'N, 11° 04'WAt 1000 hours, a steamer was sighted at 12,000 metres. Veniero closed and at 1112 hours, she dived for a submerged attack. At a distance of 1,500 metres, the vessel was recognised as the Spanish steamer Navemar (5,321 GRT, built 1921) steering 090° and the attack aborted. Navemar was sunk by the submarine Barbarigo in January 1942.

At 2345 hours on the 29th, Veniero received a BETASOM signal with the position of a convoy discovered by Argo. She had altered course to intercept when, at 0116 hours, a destroyer or sloop steering 250° was encountered. Two minutes later, she fired a torpedo (450mm, type W 200) from a stern tube. A hit was heard but the torpedo had missed. A second destroyer appeared and hunted the submarine for two hours, dropping 28 depth charges. Veniero escaped at depths between 30 and 50 metres and finally surfaced at 0305 hours. The target had been the destroyer HMS Forester and she was later joined by HMS Fury.
  30 May 19410658
(0) 35.00 N, 11.00 W approx.
At 0635 hours, a signal had been received from BETASOM relating to an enemy force and Veniero altered course to 260° to intercept. At 0658 hours, an aircraft carrier and two destroyers were sighted at a distance of 8-10,000 metres. Veniero dived immediately. At 0730 hours, three depth charges were heard but by 0840 hours, the noises had faded away. At 1035 hours, three distant explosions were heard.
  1 Jun 1941043737° 40'N, 11° 16'WAt 0437 hours, two patrol vessels were sighted.
  5 Jun 1941151033° 44'N, 9° 20'WAt 1510 hours, the Spanish steamer Sil (2,522 GRT, built 1928) was sighted.
  6 Jun 1941021534° 35'N, 11° 05'WAt 0215 hours, Veniero observed a 7,000-ton steamer and fired a torpedo (450mm, type W 200) from a bow tube. A hit was claimed and Petroni wrote that he saw her sinking, but this has not been confirmed. This was probably the British Ariosto (2,176 GRT, built 1940) from convoy OG.64 who reported being missed by torpedoes.
  6 Jun 1941021934° 35'N, 11° 05'WAt 0219 hours, as Veniero was turning she sighted a second ship estimated at 6,000 tons and fired a stern torpedo (450mm, type W 200). Another hit was claimed, but again it was not confirmed.
  8 Jun 1941134634° 38'N, 15° 00'WAt 1346 hours, a steamer was sighted. Veniero attempted to close but lost her in the mist.
  9 Jun 1941011034° 30'N, 14° 06'WAt 0110 hours, an illuminated steamer was seen. It was assumed to be neutral and was not disturbed.
  9 Jun 1941085034° 33'N, 14° 07'WAt 0850 hours, an aircraft was sighted at 10,000 metres and Veniero dived. An aircraft was again observed at 1050 hours, at the same distance. It was perhaps the same aircraft and the submarine dived again.

At 0750 hours, a Swordfish on A/S patrol for Force H sighted a submarine which had surfaced and then submerged. The aircraft attacked from a very low altitude and dropped six 100 lb A/S bombs. They failed to explode. The submarine may have been Veniero, who was in the area. Her patrol report is very brief and she may not have been aware of the attack.
  10 Jun 1941061535° 38'N, 15° 00'WAt 0615 hours, three destroyers were observed straight ahead. Veniero dived and prudently remained submerged until 1600 hours. Possibly, they were HMS Vansittart, HMS Wild Swan and HMS Wrestler, detached from Force H to Gibraltar.

Zappetta's argument that a number of his men were not in good physical conditions because of the long patrols, was refuted by Admiral Parona, who pointed out that they benefitted from a long rest between patrols. Refit until October 1941.
  10 Aug 1941155842° 20'N, 12° 16'WAt 1558 hours, an aircraft was sighted and Veniero immediately dived and remained submerged until 1750 hours.
  11 Aug 1941185545° 15'N, 10° 26'WAt 1855 hours, an aircraft was sighted and Veniero immediately dived and remained submerged until 2100 hours.
  12 Aug 1941100040° 21'N, 12° 20'WVeniero was infomed that a convoy had been reported and that Finzi and Marconi were ordered to intercept. Zappetta, who was bringing his submarine back to Italy, took the initiative to join the chase as she was in a good position. The submarine altered course to 220°, intending to intercept in 39°16' N, 13°25' W. However, at 1530 hours, Veniero received a signal from BETASOM, ordering her to 39°05' N, 13°15' W.
  12 Aug 1941170539° 23'N, 13° 05'WAt 1705 hours, an aircraft was seen. Veniero dived but was not attacked. She surfaced at 2055 hours and reached the position (39°05' N, 13°15' W) ordered by BETASOM at 2150 hours.
  13 Aug 1941010039° 05'N, 13° 55'W
(0) Italian Grid 5191/61.
At 0100 hours, a convoy of about ten ships was sighted at a distance of 8-9,000 metres steering 300° at 7 knots (probably H.G.70). One vessel was around 8,000 tons but the others were mostly of medium size,. Veniero made an enemy report at 0126 hours and attempted to penetrate the convoy. At 0305 hours, a signal from BETASOM was deciphered, ordering the submarine to transmit, starting at 0230 hours, a homing signal every 30 minutes to allow other submarines to locate the convoy. This was too late to comply as, at 0318 hours, a destroyer was sighted at 2,000 meters rushing toward her and she was forced to submerge. When she surfaced at 0505 hours, she had lost contact.
  13 Aug 1941051539° 15'N, 14° 00'W

At 0807 hours, an aircraft was suddenly observed flying low from a bank of clouds. There was no time to dive. The aircraft, identified as a seaplane of the Consolidate 28 type (Catalina), started strafing the submarine. Veniero was missed and turned to present her stern, while replying with her Breda guns, claiming several hits.

At 0820 hours, as the aircraft was at a distance, the submarine seized the opportunity to crash dive. As she reached a depth of 58 metres, she was shaken by an explosion which caused some damage. Once Veniero reached a depth of 100 metres, she escaped further attacks. The attack had been carried out by Catalina 'A' (W8410) of 202 Squadron, piloted by Squadron Leader G.P. Harger. It had begun by strafing the submarine, but had itself sustained a few hits although without serious damage. Two depth charges were released on the submarine after it had submerged, but one failed to explode.

Less than an hour later, the same aircraft attacked U-93 (KL Claus Korth). The U-boat suffered no damage.

Veniero passed the Straits of Gibraltar on 17th August without incident, only sighting the light of a patrol vessel at 0207 hours .

  7 Apr 1942221938° 25'N, 2° 58'EAt 2219 hours, in poor visibility, an aircraft suddenly appeared above the submarine at a distance of 400 metres. Veniero slowed down so that the phosphorescence of her wake could not be seen and although the aircraft apparently circled, the submarine escaped detection.

14Zappetta, Elio17 May 19421805Cagliari9 Jun 1942Date?Sunk with all handsPatrolled north of Algiers or off Balearic Islands, between 37°20'N and 37°40'N, and between 02°40'E and 03°20'E. But the same evening, a signal from MARICOSOM made a partial modification to the order by placing her in in Grids 7337 and 7381 [ca. 37°30'N, 03°00'E]. A signal of 1630 hours on 18th mentioned two aircraft carriers, a cruiser and a number of destroyers on course 050°, 20 knots in Grid 9731/4. Another signal at 1745 hours on the 18th, informed her that an aircraft carrier, a cruiser and five destroyers were reported on course 090°, 16 knots in Grid 8175/5 (37°45'N, 03°05'E). At 0950/19, the force was successively reported in (1) 36°50'N, 00°10'E (2) 36°50'N, 00°30'E (3)36°50'N, 00°50'E (Grids 2748, 2772, 2793) on course 270°. At 2339 hours on 28th May, she was ordered to move 50 miles East and 10 miles North [ca. 37°40'N, 04°00'E]. At 1625 hours on the 29th, she signalled she had located the enemy [she may have sighted the light cruiser HMS Charybdis and the destroyers HMS Westcott and HMS Wrestler who were searching for the submarine Argo, but it is not sure if they went that far east]. At 2330 hours on the 29th, she sent another signal which was indecipherable. Then was heard no more. At 1402 hours on the 30th, MARICOSOM ordered her to Grids 1163 and 1189.

At 1857 hours on 7th June, she was ordered to report her position but did not answer.

At 0208 hours on 8th June, MARICOSOM advised her that she might meet the next morning Velella and Zaffiro. Lost, cause unknown (six officers and fifty-two ratings killed).
