  8 Aug 1941031034° 50'N, 21° 50'EAt 0310 hours, a submarine was sighted on parallel but opposite course. Zoea turned away.

MARICOSOM had issued orders not to attack submarines when east of 22° E and this was close to the limit.

34° 00'N, 23° 16'EAircraft had been seen in the distance at 0700, 0900 and 0915 hours.

At 1000 hours, a fourth aircraft was sighted and circled the submarine at a distance of 2,500 metres. It finally attacked, as Zoea opened fire with her machine guns at distance of 1,500 metres. Three bombs were dropped, falling about 20 metres from the starboard bow. The aircraft attempted a second attack from the stern, Zoea opened fire with two machine guns and, as the aircraft was 500 metres away, it was hit and crashed in the sea. Zoea did not linger on the surface as three aircraft were seen approaching and she dived.

The aircraft was Blenheim 'X' (Z.6421) of 203 Squadron piloted by Flight Lieutenant Corbould. It had sighted the submarine described as small (!) in very dark colours and with no visible armament, steering 100° at 10 knots. It released four SAP bombs, one of which was seen to fall 10-15 yards off the port bow. The aircraft was not shot down as claimed and reached Mersa Matruh.

(0) Approximately.
At 0725 hours, an aircraft was sighted and it made a stern attack. Zoea opened fire with her machine guns at a range of 1,500 metres. The aircraft replied with its own machine guns but did not drop any bomb. It circled at a distance of 4,000 metres for 40 minutes and it was believed that the aircraft was summoning other bombers to attack.

At 1115 hours, a second aircraft appeared diving from the sun. The submarine made the recognition signal but was not answered and opened fire with her machine guns at a range of 2,000 metres. The aircraft strafed the submarine but did not carry out a bombing attack.
  11 Aug 1941182534° 05'N, 22° 20'EAt 1825 hours, an aircraft flying low came from the sun and strafed the submarine. Zoea opened fire at about 1,000 metres, but one of her gunners was seriously wounded. The aircraft made the reconnaissance signal of the CAT (German Air Corps) while the submarine was plainly displaying the Italian flag. This did not prevent the aircraft making another strafing run, flasing again the CAT reconnaissance signal before flying away.

At 0830 hours, a French convoy was sighted at a distance of 1,500 metres, steering 110°, 10 knots. Zoea dived to avoid being seen.

  22 Oct 19410815-0920
(0) At Taranto.
The submarine had just left the dock when she accidentally sank at her moorings sometime between 0815 and 0920 hours when the starboard mine hatch was accidentally opened.

There were a number of persons on board. The inquest recorded that some nineteen persons were in the control room at one time or another. Who could have opened the hatch by mistake? Three were electricians from the crew and the remainder workers from the S. Giorgio, Calzoni and Tosi firms and from MARICOST Taranto. There were crew members in other parts of the boat when the accident occurred.

The crew members did not panic and evacuated in good order. However, some of the workers panicked. The submarine sank slowly and Maggiore G.N Festuccia from the nearby submarine Ammiraglio Saint Bon, had time to run and board Zoea. He tried to close the hatches but was not in time and was thrown in the water. There were no victims. The submarine was raised on 5th November and docked. It took several months to be repaired, in time for operation HARPOON.

15.Tricheco (TR)21 Nov 19411455Augusta5 Dec 19411115Augusta1287,6Patrolled southeast of Malta between 34°20'N and 34°40'N, and between 16°00'E and 16°40'E (or and between 15°40'E and 16°00'E?). On a patrol line with Delfino and Settembrini.
  30 Nov 1941114734° 23'N, 15° 46'EAn enemy squadron was first detected by hydrophones at 1045 hours. They came into view and the submarine fired thee torpedoes (533mm) from her bow tubes at a range of 1,500 metres at a target described as a cruiser of the FROBISHER class, one of four cruisers and two destroyers steering 085° at 18 knots. These were actually Force B (the light cruisers HMS Ajax and HMS Neptune of the 7th C.S. with the destroyers HMS Kimberley and HMS Kingston) and Force K (the light cruiser HMS Aurora and HMS Penelope with destroyer HMS Lively). One hit was heard after 75 seconds, but this was not confirmed and the attack does not appear to have been observed. The British squadron only reported a CANT float plane sighted to the SW in position 34°24' N, 15°37' E at 1123 hours.

At 0015 hours, Dandolo had submerged to carry a listening watch. At 0100 hours, several H.E. were heard and the submarine surfaced . At 0258 hours, nothing had been seen and Campanella decided to dive again. Two minutes later, sounds were heard from two groups of vessels, one bearing 185° and the other in 215°. At 0306 hours, Dandolo surfaced again and proceeded toward the first group at 13.5 knots. At 0317 hours, the lookout on the starboard aft station reported a large dark mass bearing 120° at a distance of 4,000 metres. It was identified as an aircraft carrier. This was HMS Eagle with the light cruisers HMS Charybdis and HMS Cairo, escorted by the destroyers HMS Westcott, HMS Wrestler, HMS Ithuriel, HMS Antelope and HMS Vansittart, returning to Gibraltar from operation INSECT.

At 0322 hours, the range had dropped to 2,000 metres when Dandolo fired a full salvo of four torpedoes from her bow tubes aimed at the aircraft carrier. This was a surface attack and the submarine dived upon firing. After two minutes two explosions were heard within three seconds of each other. In fact all torpedoes had missed. On board HMS Eagle, four underwater explosions were heard, one of them close.

  12 Aug 1942180037° 39'N, 9° 45'EAt 1800 hours, an enemy naval squadron consisting of two battleships, an aircraft carrier, a cruiser and five destroyers was sighted at a distance of 9-10,000 metres, on a 090° course. Dandolo got as close as 7,000 meters before being attacked at 1830 hours by a destroyer which dropped four depth-charges causing some damage, notably to the periscope. The submarine escaped by going down to 120 meters. Some 120 depth-charges were heard until 2120 hours.
  13 Aug 19421530As Dandolo was returning to base following the damage incurred the previous day, she was informed at 1530 hours of a damaged aircraft carrier (believed to be HMS Furious). She reverted course in the hope of intercepting it but, at 1645 hours, a new signal came cancelling the previous report and the submarine returned to base.

The British squadron only reported a CANT float plane sighted to the SW in position 34°24' N, 15°37' E at 1123 hours.
Ruggiero Settimo20 Dec 19421700The submarine was ordered to patrol in Italian Grid 8860, after two unknown vessels were reported earlier in Grid 5678 on 150° course. The submarine reverted course and proceeded to this area. At 2100 hours on 21st December, she was ordered to resume her return home.
Dandolo19 Jul 1942134537.27 N, 01.57 E
(o) Approximate position.
At 1120 hours, Dandolo had been informed of an enemy cruiser and altered course to 225°. At 1345 hours, a Sunderland was suddenly sighted and the submarine quickly dived. Several bombs were heard between 1349 and 1410 hours but the submarine was not damaged.

At 0015 hours, Dandolo had submerged to carry a listening watch. At 0100 hours, several H.E. were heard and the submarine surfaced . At 0258 hours, nothing had been seen and Campanella decided to dive again. Two minutes later, sounds were heard from two groups of vessels, one bearing 185° and the other in 215°. At 0306 hours, Dandolo surfaced again and proceeded toward the first group at 13.5 knots. At 0317 hours, the lookout on the starboard aft station reported a large dark mass bearing 120° at a distance of 4,000 metres. It was identified as an aircraft carrier. This was HMS Eagle with the light cruisers HMS Charybdis and HMS Cairo, escorted by the destroyers HMS Westcott, HMS Wrestler, HMS Ithuriel, HMS Antelope and HMS Vansittart, returning to Gibraltar from operation INSECT.

At 0322 hours, the range had dropped to 2,000 metres when Dandolo fired a full salvo of four torpedoes from her bow tubes aimed at the aircraft carrier. This was a surface attack and the submarine dived upon firing. After two minutes two explosions were heard within three seconds of each other. In fact all torpedoes had missed. On board HMS Eagle, four underwater explosions were heard, one of them close.
Dandolo12 Aug 1942180037.39 N, 09.45 E
At 1800 hours, an enemy naval squadron consisting of two battleships, an aircraft carrier, a cruiser and five destroyers was sighted at a distance of 9-10,000 metres, on a 090° course. Dandolo got as close as 7,000 meters before being attacked at 1830 hours by a destroyer which dropped four depth-charges causing some damage, notably to the periscope. The submarine escaped by going down to 120 meters. Some 120 depth-charges were heard until 2120 hours.
Dandolo13 Aug 19421530As Dandolo was returning to base following the damage incurred the previous day, she was informed at 1530 hours of a damaged aircraft carrier (believed to be HMS Furious). She reverted course in the hope of intercepting it but, at 1645 hours, a new signal came cancelling the previous report and the submarine returned to base.
Uarsciek21 May 19410800-1940(o) Near Mersa Matruh?At 0450 hours, the hydrophones picked up the sounds of three vessels.

At 0800 hours, the noises intensified and until 1940 hours, Uarsciek was subjected to prolonged depth-charging, but escaped.
Uarsciek22 May 19411000-1100(o) Near Mersa Matruh?At 0430 hours, a vessel was detected with the hydrophones.

From 1000 to 1100 hours, Uarsciek was depth-charged by the vessel but managed to escape. She was again depth-charged very closely at 1600 hours, and the A/S hunt went on until 0010 hours on the 23rd.

At 0040 hours, the submarine surfaced after having spent 20 hours and 30 minutes submerged.
Uarsciek23 May 19410530-1800(o) Near Mersa Matruh?From 0530 to 1800 hours, the submarine was hunted and heard 40 depth charge explosions.
Pietro Micca19 Jan 19420935(o) Ca. 140 miles South of Santa Maria di Leuca.At 0935 hours, three aircraft were seen and Micca dived. Bomb explosions were heard but the submarine escaped damage.
Pietro Micca25 Jan 19421200(o) Tripoli harbour.At noon, the submarine was visited by Generals Cavallero (Head of Comando Supremo) and Bastico (Head of Axis Forces in North Africa).
Zoea8 Aug 1941031034.50 N, 21.50 E
At 0310 hours, a submarine was sighted on parallel but opposite course. Zoea turned away.

MARICOSOM had issued orders not to attack submarines when east of 22° E and this was close to the limit.
Zoea8 Aug 19411000

34.00 N, 23.16 E
(e) 34.08 N, 23.04 E
Aircraft had been seen in the distance at 0700, 0900 and 0915 hours.

At 1000 hours, a fourth aircraft was sighted and circled the submarine at a distance of 2,500 metres. It finally attacked, as Zoea opened fire with her machine guns at distance of 1,500 metres. Three bombs were dropped, falling about 20 metres from the starboard bow. The aircraft attempted a second attack from the stern, Zoea opened fire with two machine guns and, as the aircraft was 500 metres away, it was hit and crashed in the sea. Zoea did not linger on the surface as three aircraft were seen approaching and she dived.

The aircraft was Blenheim 'X' (Z.6421) of 203 Squadron piloted by Flight Lieutenant Corbould. It had sighted the submarine described as small (!) in very dark colours and with no visible armament, steering 100° at 10 knots. It released four SAP bombs, one of which was seen to fall 10-15 yards off the port bow. The aircraft was not shot down as claimed and reached Mersa Matruh.
Zoea10 Aug 19410910+(o) At Bardia.General Rommel and General Count Giorgio Carlo Calvi di Bergolo visited the submarine.
Zoea11 Aug 1941072534.05 N, 22.20 E
(o) Approximately.
At 0725 hours, an aircraft was sighted and it made a stern attack. Zoea opened fire with her machine guns at a range of 1,500 metres. The aircraft replied with its own machine guns but did not drop any bomb. It circled at a distance of 4,000 metres for 40 minutes and it was believed that the aircraft was summoning other bombers to attack.

At 1115 hours, a second aircraft appeared diving from the sun. The submarine made the recognition signal but was not answered and opened fire with her machine guns at a range of 2,000 metres. The aircraft strafed the submarine but did not carry out a bombing attack.
Zoea11 Aug 1941182534.05 N, 22.20 E
At 1825 hours, an aircraft flying low came from the sun and strafed the submarine. Zoea opened fire at about 1,000 metres, but one of her gunners was seriously wounded. The aircraft made the reconnaissance signal of the CAT (German Air Corps) while the submarine was plainly displaying the Italian flag. This did not prevent the aircraft making another strafing run, flasing again the CAT reconnaissance signal before flying away.
Zoea12 Aug 1941083036.00 N, 20.00 E
(o) Approximately.
At 0830 hours, a French convoy was sighted at a distance of 1,500 metres, steering 110°, 10 knots. Zoea dived to avoid being seen.
Zoea22 Oct 19410815-0920(o) At Taranto.The submarine had just left the dock when she accidentally sank at her moorings sometime between 0815 and 0920 hours when the starboard mine hatch was accidentally opened.

There were a number of persons on board. The inquest recorded that some nineteen persons were in the control room at one time or another. Who could have opened the hatch by mistake? Three were electricians from the crew and the remainder workers from the S. Giorgio, Calzoni and Tosi firms and from MARICOST Taranto. There were crew members in other parts of the boat when the accident occurred.

The crew members did not panic and evacuated in good order. However, some of the workers panicked. The submarine sank slowly and Maggiore G.N Festuccia from the nearby submarine Ammiraglio Saint Bon, had time to run and board Zoea. He tried to close the hatches but was not in time and was thrown in the water. There were no victims. The submarine was raised on 5th November and docked. It took several months to be repaired, in time for operation HARPOON.
Zoea19 Jun 19420503At 0503 hours, the submarine Micca was sighted.
