At 1355 hours, a steamer was sighted at 15,000 metres steering 227°. Shortly after, a second steamer was sighted at 13,000 metres, steering 090°. Serpente lost contact with the first one, then closed the second ship at 1650 hours, at a distance of 1,000 meters. She was identified as the Vichy French Sainte Germaine (1,626 GRT, built 1919).
  5 Sep 19412003
(0) Off Cape Caxine.
At 2003 hours, a 5-6000-ton tanker was sighted steering a southerly course at 12-13 knots. At 2200 hours, Serpente had closed to 1,500 meters and identified her as French.

At 1430 hours, Serpente was informed of the presence of an enemy naval force (this was the HALBERD convoy). Because of the heavy rain, the submarine dived to 30 meteres to get better acoustic conditions for her hydrophones.

At 1540 hours, nothing could be heard and the submarine returned to periscope depth.

At 1618 hours, the upper works of what appeared to be a battleship were seen at 10,000 metres.

At 1640 hours, the formation identified as a battleship and four destroyers was attacked. Serpente fired two stern torpedoes at less than 1,000 metres at a JAVELIN class destroyer as the battleship was not in a good position for attack. At the same time, a destroyer was sighted at 1,300-1,500 metres suddenly turning toward the submarine who crash-dived. An explosion was heard after 40-50 seconds leading T.V. Ferrini to believe he had scored a hit.

Serpente was depth charged between 1703-1722 hours. Her tormentor was the destroyer HMS Lively who dropped 14 depth charges at 1705 hours and was assisted by HMS Legion for the A/S hunt. The submarine had escaped by going down to 100 metres and stopping her machines. She surfaced at 1945 hours to find that the enemy was gone.

  15 Jul 19422000
(0) 12° - La Galite Island - 5.5 miles.
At 1940 hours, an enemy ship was sighted at distance of 8,000 metres, steering 120°. It was identified as a cruiser, proceeding at 20 knots.

At 2000 hours, three torpedoes were fired from bow tubes at a distance of 1,800-2,000 metres. They missed. Axum dived and reached the bottom at 50 metres. She returned to periscope depth at 2020 hours, but sighted nothing.

This was most probably the minelayer HMS Welshman on her way to Malta where she arrived at dawn the following day.

17.Axum (AX)29 Jul 19421818Cagliari9 Aug 19421246Trapani859Patrolled north of the Tunisian coast, between 37°20'N and 37°50'N, and 09°20'E and 09°40'E, off Ras Agheila and Cape Blanc. Sighted many French ships. Uneventful.

  12 Aug 19421955
1956 (e)
37° 36'N, 10° 22'EAt 1821 hours, a vessel was sighted, which was thought to be a large steamer or perhaps an aircraft carrier. Axum dived to close.

At 1927 hours, a look through the periscope revealed the enemy formation at a distance of 8,000 metres, steering 110°.

At 1955 hours, four torpedoes were fired from the bow tubes, at distances varying from 1,300 to 1,800 metres. The submarine went deep. After 63 seconds an explosion was heard, followed by two more after 90 seconds.

It was one of the most outstanding attacks of the war. The light cruiser HMS Nigeria was the first hit and badly damaged (fifty-four killed or missing, two wounded). The light cruiser HMS Cairo had her stern blown off (twenty-three killed or missing). The destroyer HMS Pathfinder and the escort destroyer HMS Derwent finished her off with torpedoes and she sank at 2135 hours (twenty-nine officers and 383 ratings were taken off including eight wounded). The American tanker Ohio (9.264 GRT, built 1940) was badly damaged, but her saga was just beginning and by incredible feats of courage, she would reach Malta, bringing badly needed relief.

Axum had reached a depth of 65 metres when she was first depth charged, she escaped damage by going down to 100-120 metres. The submarine surfaced at 2250 hours to witness three vessels on fire. She later received the order to finish off the stragglers, but had no opportunity to do so.

23.Ambra (AM)14 Jul 19431532La Spezia18 Jul 19431410MessinaPassage La Spezia-Messina, carrying three human torpedoes destined to force the harbour of Syracuse (also reported as three explosive boats to attack Augusta). At 2030 hours on the 16th, she met the torpedo boat Partenope in point M3 to escort her through the Strait of Messina.

(0) South of San Rainieri Light (Strait of Messina).
At 0035 hours, Ambra was being escorted by the torpedo-boat Partenope, when they received the order to stop off Messina as the light cruiser Scipione Africano was expected to cross the Straits shortly.

At 0210 hours, Scipione Africano was observed firing at unidentified naval targets.

A vessel was set afire. This actually was MTB-316 . She was sunk and none of her eleven-men crew survived. MTB- 313 was hit and had one killed and one wounded. The MTBs claimed two torpedo hits on the cruiser, but Scipione Africano was undamaged.
  17 Jul 1943223237° 28'N, 15° 58'EAt 2232 hours, five enemy vessels were sighted at a distance of 12,000 metres. Ambra had instructions not to reveal its presence until her special mission was accomplished and desisted from attacking.

At 0320 hours, an aircraft was sighted, which made a recognition signal before bombing the submarine with depth-charges. Ambra was straddled by seven or eight bombs, damaged by near-misses and had a few wounded. As she could no longer submerge, she was forced to abort her mission. She returned through the Strait of Messina escorted by the corvette Cicogna and the torpedo-boat Partenope who took her in tow part of the trip back to Naples. A submarine was reported lurking near them at 1915 hours on the 18th and the corvette Cicogna was detached to hunt it. Ambra and Partenope proceeded together to Naples.

This was Wellington 'B' (HZ.116) of 221 Squadron piloted by Pilot Officer E. Austin. Post-war, this attack was initially credited to have sunk the submarine Romolo, although she was assessed at the time as "probably slightly damaged". The aircraft had detected the submarine from a range of 6 miles and made an attack by keeping the target in its moonpath. Five 250-lb depth charges set at 25 feet and three A/S 100-lb bombs were released from a height of 200 feet. The submarine was reported to have fired a short burst of machine gun fire as the aircraft flew away. It was not hit. The aircraft attempted to contact British destroyers known to be operating in the area, without success.

Ambra left them at 1840 hours on the 26th, off Piombino. She was reported damaged more seriously than at first thought. It was proposed that following the entry in service of Murena (at the end of September) and Grongo (on 20th October 1943), she was to revert to ordinary submarine operations.
