(0) Off Cyrenaica.
At 1810 hours, a vessel believed to be an Italian torpedo boat, was sighted at a distance of 1,500 metres. By precaution, Dessié dived. This was actually the submarine Settembrini.
  2 Nov 1940013532° 25'N, 25° 54'EAt 0135 hours, a submarine was briefly sighted in very poor visibility at a distance from 150 to 50 metres. It was believed to have been Luigi Settembrini, but she did not report any sighting and no British submarine operated in the vicinity.

36° 30'N, 12° 59'EAt 0302 hours, a naval squadron was sighted at a distance of 4,000 metres. It consisted of three large units proceeding in single file and steering 270° at 20 knots.

At 0305 hours, two torpedoes (one 533mm and one 450 mm) were fired from the stern tubes at a range of 3,500 metres, aimed at the second ship. Dessié dived upon firing and two hits were heard. In fact, both had missed.

The targets were the heavy cruiser HMS York and the light cruisers HMS Gloucester and HMS Glasgow. They also heard one explosion but this was probably a torpedo detonating at the end of its run. It must also be noted that these three ships heard two detonations at 0138 hours in 36°57' N, 11°37' E but these were probably from the attack by the torpedo boat Calliope.

1956 or 2058? (e)
37° 38'N, 10° 25'EAt 1900 hours, the smokes of the convoy were sighted on the horizon. Ten minutes later, fourteen merchant ships and ten destroyers could be counted. They were steering 110° at 14 knots.

At 1938 hours, four torpedoes (533mm) were fired at 3-second intervals from the bow tubes, at a distance of 1,800 metres. After 100 seconds, two hits were heard. Between 1956 and 2127 hours, Dessié was hunted and escaped to a depth of 90 metres; 120 depth charges were counted, but none were near enough to cause damage. There was no opportunity for an attack with the stern tubes as it was hoped.

There is no absolute certainty that Dessié hit anything with this salvo. Some accounts credit her with hitting Deucalion (7,516 GRT, built 1930) but she was near-missed at 1315 hours by a bomb and damaged. Later, she was hit by a torpedo bomber and sunk at 2120 hours in 270° - Cani Rocks - 5 miles. Brisbane Star is also reported to have been torpedoed by aircraft at 2058 hours. Was she damaged earlier? There was great confusion in these hours and it is difficult to properly assess what transpired.

At 2212 hours, Dessié surfaced and witnessed two vessels on fire.

At 1755 hours, Dessié was attacked in error by four German Junker 88 bombers despite her frantic signals. They each dropped four bombs. They missed by about 50 metres.

At 1935 hours, the submarine was attacked once again by German aircraft, this time she was narrowly straddled and damaged by near-misses. T.V. Scandola, three officers and three ratings were wounded, one rating was killed. The submarine had to abort her patrol.

On 30th November, she was to leave her patrol at 1800 hours on the 30th, to return to Naples via (1) 37°20'N, 08°00'E at 1830/30 (2) 39°00'N, 10°20'E at 1100/1 (3) 40°00'N, 11°20'E at 1800/1 (4) Point C (Naples) at 0700/2. Sunk off Bone by the destroyers HMAS Quiberon and HMS Quentin in 37°04'N, 07°49'E (five officers and forty-two other ranks lost, no survivors).

At 1212 hours, the destroyer HMS Quentin sailed from Bône, following a report from an aircraft that a submarine was sighted in the vicinity at 1145 hours. She was later joined by the destroyer HMAS Quiberon who sailed at 1318 hours.

At 1250 hours, the destroyer picked up an ASDIC contact at 2,000 yards.
At 1254 hours, ten depth charges were dropped, set from 100 and 225 feet.
At 1308 hours, ten depth charges were dropped, set from 150 and 385 feet.
At 1330 hours, ten depth charges were dropped, set from 350 and 550 feet (bubbles and oil were sighted).
At 1359 hours, ten depth charges were dropped, set from 50 and 140 feet.
At 1407 hours, ten depth charges were dropped, set from 150 and 385 feet.
At 1525 hours, HMAS Quiberon joined in the attack by dropping five depth charges set at 385 feet (more bubbles and a black object were seen).
At 1533 hours, HMS Quentin dropped a final pattern of ten depth charges set at 350 and 550 feet.

At 1356 hours, the U-boat broke surface, the bow emerging vertically. The bow disappeared and reappeared until the entire boat was visible on the surface. This lasted only a minute and a half before the submarine slid underwater, stern first, with the bow disappearing vertically. The destroyers had opened fire with 4,7" guns and smaller weapons, without scoring a hit. None of the submarine's crew appeared on deck or on the bridge.

There is little doubt that this was Dessié. There were no survivors. T.V. Alberto Gorini, four officers and forty-two other ranks perished.

Adriano Pini26 Oct 19401810(o) Off Cyrenaica.At 1810 hours, a vessel believed to be an Italian torpedo boat, was sighted at a distance of 1,500 metres. By precaution, Dessié dived. This was actually the submarine Settembrini.
Adriano Pini2 Nov 1940013532.25 N, 25.54 E
At 0135 hours, a submarine was briefly sighted in very poor visibility at a distance from 150 to 50 metres. It was believed to have been Luigi Settembrini, but she did not report any sighting and no British submarine operated in the vicinity.

At 0302 hours, a naval squadron was sighted at a distance of 4,000 metres. It consisted of three large units proceeding in single file and steering 270° at 20 knots.

At 0305 hours, two torpedoes (one 533mm and one 450 mm) were fired from the stern tubes at a range of 3,500 metres, aimed at the second ship. Dessié dived upon firing and two hits were heard. In fact, both had missed.

The targets were the heavy cruiser HMS York and the light cruisers HMS Gloucester and HMS Glasgow. They also heard one explosion but this was probably a torpedo detonating at the end of its run. It must also be noted that these three ships heard two detonations at 0138 hours in 36°57' N, 11°37' E but these were probably from the attack by the torpedo boat Calliope.
Renato Scandola6 Jun 1941Time?35.55 N, 20.10 E
During the day (probably morning, time not given), a derelict mine was fired upon (250 rounds of 13mm and 80 rounds of 6.5mm ammunition) but without sinking it.
Adriano Pini8 Sep 19410930(o) Makri Sophrano Islet (southernmost of the Sopkrana Nisia group).At 0930 hours, due to an error in navigation, Dessié hit a rock with some damage to her bow. T.V. Adriano Pini and two others received a reprimand.
Adriano Pini7 Dec 19410430(o) Off Cape Pappas.At 0430 hours, a vessel was sighted at a distance of 12,000 metres, followed by another at 0457 hours. Dessié closed to investigate. These proved to be the Italian Bucintoro (1,273 GRT, built 1909) escorted by the auxiliary Canogli on their way to Leros. They exchanged signals and closed to voice range to ascertain their respective identities.
Adriano Pini5 May 1942122138.26 N, 09.46 E
At 1221 hours, a derelict mine was sunk after an expenditure of 170 rounds of 13.2mm and 13 rounds of 9mm ammunition.
Adriano Pini22 May 1942175038.21 N, 11.00 E
At 1750 hours, a derelict mine was sunk after an expenditure of 90 rounds of 13.2mm ammunition.
Renato Scandola19 Jun 19421920(o) Near La Galite.At 1920 hours, a Catalina aircraft was sighted at a distance of 8,000 metres. The aircraft did not sight the submarine and Dessiè remained on the surface.
Renato Scandola18 Jul 19421755(o) Off Kelibia (Tunisia).At 1755 hours, the Italian steamer Saturno (5,022 GRT, built 1914) was sighted proceeding independently to Tripoli. T.V. Scandola observed that the torpedo-boat escort (Orione) was not present.

At 1900 hours, the smokes of the convoy were sighted on the horizon. Ten minutes later, fourteen merchant ships and ten destroyers could be counted. They were steering 110° at 14 knots.

At 1938 hours, four torpedoes (533mm) were fired at 3-second intervals from the bow tubes, at a distance of 1,800 metres. After 100 seconds, two hits were heard. Between 1956 and 2127 hours, Dessié was hunted and escaped to a depth of 90 metres; 120 depth charges were counted, but none were near enough to cause damage. There was no opportunity for an attack with the stern tubes as it was hoped.

There is no absolute certainty that Dessié hit anything with this salvo. Some accounts credit her with hitting Deucalion (7,516 GRT, built 1930) but she was near-missed at 1315 hours by a bomb and damaged. Later, she was hit by a torpedo bomber and sunk at 2120 hours in 270° - Cani Rocks - 5 miles. Brisbane Star is also reported to have been torpedoed by aircraft at 2058 hours. Was she damaged earlier? There was great confusion in these hours and it is difficult to properly assess what transpired.

At 2212 hours, Dessié surfaced and witnessed two vessels on fire.
Renato Scandola13 Aug 1942175537.35 N, 10.24 E
(o) Off Tunisian coast.
At 1755 hours, Dessié was attacked in error by four German Junker 88 bombers despite her frantic signals. They each dropped four bombs. They missed by about 50 metres.

At 1935 hours, the submarine was attacked once again by German aircraft, this time she was narrowly straddled and damaged by near-misses. T.V. Scandola, three officers and three ratings were wounded, one rating was killed. The submarine had to abort her patrol.
