  18 Jan 19421950The submarines were ordered by signal (1954/18) to form a patrol line to intercept the convoy from Alexandria reported in the afternoon: Santarosa in Italian Grid 0132 (34°30' N, 15°30' E), Squalo in Grid 8332 (probably 35°20' N, 15°30' E) and Narvalo in Grid 2732 (probably 35°02' N, 15°30' E). Narvalo proceeded to the new position but sighted nothing.

A torpedo wake was sighted and the submarine took evading action. The torpedo passed either under her stern or very close to it. Four explosions were heard which were probably of torpedoes at the end of their run. The attack had been carried out by HMS Utmost (Lt. J.W.D. Coombe, RN). The British submarine had fired four torpedoes from a range of only 400 yards.

10.Enrico Tazzoli (TZ, I.3)16 May 19431200La Pallice17 Jun 1943Sunk with all handsPassage Bordeaux-Singapore with 165 tons of stores with passenger Japanese Colonel Kihara and German Lt. Chiari and nine others via: (1) 45°30'N, 11°00'W (2) 35°00'N, 21°00'W (3) 17°00'N, 28°00'W [was to have met Giuliani in 09°30'S, 06°30'W on 17 June] (4) 15°00'S, 01°00'W (5) 36°30'S, 16°00'E (6) 37°40'S, 18°00'E (37°40'S, 26°00'E then Sunda Straits. From German sources kindly provided by Dr Axel Niestlé, Tazzoli and Giuliani left La Pallice at 1200 under escort of M 83, M 84 and Sperrbrecher 21 via Points P1 and point Pilz. Point Pilz (BF 6848 or 45°57' N, 02°15' W) was reached at 1632 and both boats then proceeded independently. (Originally, departure planned for 15.05.43, but delayed). Believed lost between 17th and 24th May 1943, six officers, forty-six ratings, and five civilians killed. The destroyer USS Mackenzie (DD-614) attacked a submarine on 16th May in 38°53'N, 20°33'W and another on 22nd May. It is impossible that it was the first attack. She was to rendezvous with another unit [Giuliani] in 09°30'S, 06°30'W on 17th June, but never showed up.
  16 May 1943
2003 (e)

(e) 45° 57'N, 11° 40'W
At 2003 hours, Halifax 'R' (HR774) of 58 Squadron (piloted by Pilot Officer A.J.W. Birch) attacked a submarine with depth-charges. It was claimed that Enrico Tazzoli was sunk in this attack but it is unlikely, as she could never have reached this position in time.
  20 May 1943
1000 (e)

(e) 45° 50'N, 9° 27'W
At 1000 hours, Liberator 'A' (Flying Officer J.R. Weeds) of 224 Squadron sighted a submarine on course of 270 degrees at 8 knots. The bomber attacked from port quarter and a stick of six depth charges was released from 100 feet, 45 seconds after the U-boat had disappeared. The rear gunner witnessed the explosions, estimating four on the submarine's track about 400 feet ahead of the swirl. Baiting tactics were carried out but nothing further was observed. It is possible that Enrico Tazzoli was sunk in this attack.
  21 May 1943
0925 (e)

(e) 45° 54'N, 15° 29'W
At 0925 hours, an aircraft of 19 Group reported to be over a submarine. Details of this attack are unknown but it remains a possibility that this was Enrico Tazzoli.

1718Z (e)

(e) 34° 30'N, 13° 13'W
At 1718Z hours, an American PBY (from VP-92?) sighted two U-boats and attacked one of them. Another aircraft sighted one corpse and debris in a large oil slick in the vicinity. It is possible that this was Enrico Tazzoli. The submarine disappeared without a trace. Believed lost between 17th and 24th May 1943, six officers, forty-six ratings and five civilians killed.
