Patrols and events
|Commander||Date||Time||Port||Arr. date||Arr. time||Arr. port||Miles||Description|
|D'Elia, Renato||10 Jun 1940||Taranto||10 Jun 1940||Taranto||At Taranto.|
|1||D'Elia, Renato||17 Jun 1940||2330||Taranto||2 Jul 1940||0750||Taranto||2169,8||Patrolled between 40°40'N and 41°20'N and 02°40'E and 03°20'E, 40 miles southeast of Barcelona up to 27 June.|
|21 Jun 1940||1144|
|39° 51'N, 5° 10'E||At 1144 hours, a formation of twelve aircraft was sighted at a distance of 3,500 metres. They attacked Malachite who dived. She reached 44 meters when she was shaken by an explosion, which caused slight damage.|
This could have been French T 2 Squadron (Laté.29-8 seaplanes evacuating from Berre to Bougie) which attacked a submarine with five aircraft. The attack is reported as havinf occured on 22 June, but refers to a signal from Marine Bougie of 1325 hours on 21st June, so the date is probably an error. The attacks were carried out by T 21 piloted by L.V. Lamiot (unable to drop his bomb), T 22 (did not attack), T 23 piloted by L.V. Jourdain (dropped a bomb, which did not explode), T 210 piloted by E.V. Grosclaude (dropped a bomb which exploded), T 27 piloted by Maître Le Gall (dropped a bomb) and T 21 which made a second run and dropped a bomb, but it did not explode.
|24 Jun 1940||2202||41° 18'N, 2° 44'E||At 2202 hours, a tanker was sighted at a distance of 5,000 metres followed shortly after another four merchant vessels. Malachite tried to close the range unsuccessfully and the heavy seas prevented a gun action.|
|28 Jun 1940||1350||39° 48'N, 5° 22'E||At 1350 hours, a submarine was sighted at a distance of 3,500 metres, steering 340° in heavy seas. C.C. Renato d'Elia decided not to attempt an attack as he believed it might be Nani. This could not be, as she had already reached Naples. Possibly this could have been either Ascianghi, Cappellini or Mocenigo but their patrol reports are not precise enough to determine which one.|

|14 Feb 1941||0106|
(0) Off Cyrenaica.
|At 0106 hours, a dark silhouette, believed to be a cruiser or a destroyer, was sighted on an easterly course. Malachite attempted to close the range but, at 0100 hours on the 21st, the enemy vessel passed some 6 to 7,000 meters away and disappeared in the distance.|
|Zanni, Enzo||6 Mar 1941||0805||Messina||6 Mar 1941||1535||Messina||39||Exercises, escorted by R.D.57.|

|19 Mar 1941||0109||33° 00'N, 26° 40'E||Since the previous evening, noises had been picked up by the hydrophones without resulting in any visual confirmation.|
At 0030 hours, hydrophone effects were picked up again. At 0055 hours, in heavy mist, a shadow was finally sighted,followed shortly after by another. They were believed to be a SOUTHAMPTON class cruiser and a destroyer steering 050°-040° at 18 knots
At 0109 hours, Malachite fired two bow torpedoes from the surface, at a range of 2,500 metres, aimed at the cruiser. They missed. A third torpedo was about to be fired when the destroyer suddenly turned toward the submarine. Malachite crash-dived. Two depth charges were heard, followed by two more.
The target was possibly the light cruiser HMS Gloucester escorted by the destroyer HMS Hasty on passage from Alexandria to Piraeus via the Kythera Channel and carrying General Blamey and 1,087 troops of the Australian corps.

|17 Apr 1941||0149|
(0) Ca. 100 miles North of Sidi Barrani.
|At 0149 hours, an enemy destroyer was sighted at a distance of 2,000 metres and she turned toward the submarine. Malachite crash-dived but the voice pipe had not been closed causing a large amount of water to penetrate the submarine. It was finally closed and the submarine went down to 80 meters and appeared to pick up sounds from a passing convoy on her hydrophones . She surfaced at 0212 hours but did not sight anything.|
|17 Apr 1941||2000|
(0) Ca. 100 miles North of Sidi Barrani.
|At 2000 hours, information was received of a large heavily escorted convoy. Malachite altered course to intercept but nothing was sighted or heard.|
|18 Apr 1941||2000|
(0) Ca. 100 miles North of Sidi Barrani.
|At 2000 hours, information was received of a large convoy steering 300°. Malachite steered west to intercept.|
Between 1700 and 1900 hours on the 20th, Malachite was on her way to Augusta when a series of distant explosions were heard. This was believed to be from a convoy under air attack, but nothing was sighted.

|3 Jul 1941||2007|
(0) Off Ras Azzaz (UK: off Mersa Matruh).
|At 1937 hours, Malachite was submerged when noises were picked up with the hydrophones. Nothing could be observed with the periscope, so she surfaced at 1946 hours.|
At 1947 hours, two destroyers were sighted zigzagging and firing at aircraft at a distance of 6-7,000 metres. As they were closing toward the submarine, Malachite submerged at 1957 hours, but again nothing could be observed through the periscope. Surfacing at 2004 hours, she immediately sighted a DIDO class cruiser with two destroyers.
At 2107 hours, a single torpedo was fired from a bow tube at a distance of 2,500 metres aimed at the cruiser and the submarine crash-dived. Two torpedoes were intended, but the first had misfired. After 150 seconds, a loud explosion was heard and it was believed that the cruiser had been hit.
These were actually the destroyers HMS Defender, HMAS Stuart and HMAS Vendetta on their way to Tobruk. HMS Defender sighted the torpedo track and avoided it. HMAS Stuart sighted the submarine's conning tower and rushed to the attack, dropping two depth charges. HMS Defender hunted the submarine without success.
Italian Naval Intelligence had intercepted a signal from the light cruiser HMS Phoebe reporting an attack (she was actually operating off the Syrian coast) and deduced that she was undamaged but that possibly one of the destroyers had been hit.

|During the evening of 21st, January, Malachite had been informed of the passage of an important convoy steering eastward.|
At 0415 hours on the 22nd, Malachite was proceeding at a depth of 35 metres, when she was violently shaken by bomb explosions, seemingly directly above her. A minute later, the hydrophones picked up numerous noises, presumably for the expected convoy.
At 0455 hours, the convoy came into view at a distance of 10,000 metres. It appeared to consist of ten 5-10,000-ton merchants, including tankers, escorted by three destroyers, steering 120°, 8 knots. One destroyer briefly appeared to alter course toward the submarine, before returning to the convoy, then came back again. T.V. Alpino Cinti, believing he had been discovered, elected to attack the destroyer instead. The target was now steering 015° at 16 knots.
At 0518.40 hours, four torpedoes (533mm, G7e type) were fired from the bow tubes at a distance of 1,100 metres. Malachite immediately went deep. She had barely reached a depth of 3 or 4 metres when a double explosion was heard. No depth charging followed and the submarine moved away from the area.
At 1134 hours, she was at a depth of 30 metres when explosions were heard close by and it was believed that she may have been spotted by an aircraft. She was undamaged and resumed her patrol.
|23 Jan 1943||0800-0830||38° 36'N, 8° 23'E||At 0830 hours, a derelict mine was sighted at a distance of 1,000 metres. Malachite closed to 500 metres, expending 120 machine gun rounds but did not succeed to sink it.|

Alpino Cinti, three officers, nine ratings were picked up by the Italian minesweeper Arcioni and the fishing vessel Dori. One officer and thirty-four ratings were lost. A reconstructed patrol report was made.|
|6 Feb 1943||0345||36° 57'N, 3° 26'E||At 0345 hours, two destroyers were sighted at a distance of 4,000 metres, steering 270°, 20-25 knots. Malachite could not gain a good attack position.|

|At 2110 hours, ten saboteurs of Italian Special Forces (1st battalion of the 10th Arditi Regiment) were landed on the Algerian coast in three boats. Their objective was a railway bridge about 30 km east of Algiers. The landing was successful. Malachite returned at 0558 hours on the 7th to pick them up but they failed to show up. The ten men had been captured.|

|At 1103 hours, Malachite had just entered the searched channel leading to Cagliari, when the lookout, 2° Nocchiere (2nd Helmsman) Sisto Fosci, spotted torpedo tracks coming from the port side. The helm was immediately put hard to starboard. The first torpedo missed 50 metres ahead, the second 5-10 metres and the third only about one metre from the bow, but the fourth hit the submarine aft. The explosion was not very great and looked more like a large shell hit but the submarine sank stern first in about 50 seconds. About 20 minutes later, the auxiliary minesweeper Arcione and the fishing vessel Dori arrived on the scene and picked up the survivors. T.V. Alpino Cinti, three officers, nine ratings were the only ones found. One officer and thirty-four ratings were lost.|
The attack had been made by the Dutch submarine HrMs Dolfijn (Lieutenant Commander H.M.L.F.E. van Oostrom Soede). At 1048 hours, she had sighted a submarine described as of the GEMMA class at a distance of 2 miles.
At 1059.5 hours, she had fired a salvo of four torpedoes from a range of 2,200 yards at 8.5-second firing intervals. One explosion was heard and when the periscope was raised, the target was observed to sink by the stern.
