(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.|

|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.

(0) Very approximately.
|At 2327 hours, two liners (10,000 to 20,000 GRT), escorted by two destroyers, were sighted at 7,000 metres, steering 100°. Malachite could not close to the attack.|

(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.

(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.

|At 1943, hydrophones detected noises and Malachite steered toward them. |
At 2046 hours, a destroyer was sighted at a distance of 7,000 metres, steering 250° at 30 knots. The submarine could not gain an attacking position.
