From 1830 to 1900 hours, noises were heard and interpreted as a large enemy force on an easterly course. Aradam did not carry out an attack as is implied in the Seekriegsleitung diaries.

At 0619 hours, two explosions were heard from the direction of Diaspro's patrol area. It was believed she had hit a vessel. This was the attack on HMS Gurkha, which had failed.

Noises were heard on the hydrophones off and on since 1211 hours.

At 1405 hours, five enemy destroyers were sighted at a distance 6-7,000 metres, steering 165°. Aradam attempted to close, but they passed out of range.

At 1649 hours, an explosion was heard and it was believed that Serpente, in the adjacent area, had scored a hit. This attack against HMS Legion had also failed.

At 0020 hours, flashing lights was seen in heavy rain. It was believed these were perhaps the cruiser and two destroyers reported by MARICOSOM. Aradam steered toward them but visibility was poor. It was later recognised as a French vessel, probably "Toutquenois" (?) on passage from Bone to Marseilles.
  1 Oct 19410820
(0) Between Cape de Fer, Cape Serrat and La Galite.
At 0820 hours, a submarine was sighted. It was believed to be Diaspro who had probably sighted Aradam and submerged.

Aradam closed submerged and, at 1955 hours, surfaced for gun action at a range of 6,000 meters. The vessel turned away at full speed and disappeared before a shot could be fired.

At 1220 hours, information was received from MARICOSOM that an aircraft had seen at 1010 hours, a derelict vessel believed to be Empire Pelikan (sic Empire Pelican) and ordered her to pick up the survivors. Empire Pelican and Empire Defender had both been sunk by Italian torpedo-bombers.

Aradam looked for the survivors but without success. In fact, the twenty-five survivors of Empire Pelican had taken to four lifeboats and reached Cape Seurat the same afternoon.

At 2000 hours on the 3rd, she obtained a fix which showed she had been out of position by 45 miles.

At 1418 hours, information was received of an enemy cruiser of 7,000 tons, 10 miles southeast of Galite Island, steering 270°, 20 knots. Aradam surfaced at 1452 hours and proceeded toward the south at maximum speed but sighted nothing.

0045 (e)
38° 25'N, 7° 56'EAt 0152 hours, a submarine was sighted at a distance of 1,500 metres, steering 240°. It could have been Italian. Aradam steered away. It was actually the Dutch HrMs O 23 (Luitenant ter zee 1e klasse (Lt. Cdr.) Albertus Marinus Valkenburg), on passage direct from Gibraltar to Alexandria.

23Gran, Oscar4 Apr 19420103Cagliari22 Apr 19421028Cagliari566,5Patrolled in zone Kappa 2 (K 2), off Kelibia (Tunisia), on a barrage line with Turchese (in zone K 1).
  6 Apr 1942031736° 47'N, 11° 05'EAt 0312 hours, the First Officer sighted a wake at a distance of 2,500 metres. It was very quickly recognised to be a destroyer and initially believed to be proceeding at a moderate speed of about 16 knots.

At 0317 hours, it was realised that the vessel was going faster (25 knots) than estimated. One torpedo (533mm, type H) was fired from a bow tube at a distance of 470 metres. The order to fire a second torpedo was not understood as the noise of the "senza bolla" (bubbleless) system covered the voice. The submarine crash-dived immediately and no hit was heard but it was believed that the torpedo may have struck the stern. In fact the torpedo had missed.

The target was the destroyer HMS Havock who was actually doing 28-30 knots. However, at 0358 hours, she ran hard aground in position 020° - Kelibia Light - 2.5 miles (approx. 36°52' N, 11°08' E or about 6 miles from Aradam's attack position). No explanation could be given on how the destroyer had beached herself near Cape Mirh (about 2.5 miles north of Cape Mustafa ) some 39 minutes later (according to the Italians which was accurate enough). The theory was that she was hit and managed 7 knots before beaching herself. In fact, either she was much further south than recorded or, the time was wrong.

At about 1500 hours MAS 563 (T.V. Renato Castello) and MAS 564 (G.M. Francesco Luciano) from Pantelleria arrived on the scene and met the French minesweeper Héron who informed them that the crew of H.43 (HMS Havock) had been interned. The two Italian boats tried to examine the wreck, but when they were only half a mile from her, the forward part exploded and she was broken in two.
  9 Apr 1942051936° 47'N, 11° 07'EAt 2142 hours on 8th April, information was received that a cruiser and destroyer were expected to go through Aradam's zone at about 0100 hours on the 9th.

At 0519 hours on the 9th, the cruiser and destroyer were suddenly sighted at a distance of 1,000 metres. As they steered straight for the submarine, Aradam crash-dived. The two vessels passed so close that an attack with stern torpedoes was impossible.

This was the light cruiser HMS Penelope, proceeding from Malta to Gibraltar. ' HMS Pepper Pot ', as she had been nicknamed, was proceeding unescorted. Despite her damages, she had managed a very credible 29 knots, for a few hours, but was now proceeding at 20 knots as she closed Cape Bon. During, the day she was the subject of several air attacks, but reached her destination at dusk the following day, having averaged 27 knots for most of the journey
  18 Apr 1942150335° 50'N, 11° 08'EAt 1503 hours, a steamer was sighted at a distance of 1,000 metres. An attack was about to be carried out as the vessel had not been announced, when a CANT Z.506 was observed flying close to the steamer, so it was assumed to be Italian.
  19 Apr 19421006
(0) Off Cape Bon.
At 1006 hours, the Italian steamer Nino Claudio (2,571 GRT, built 1941) was sighted at a distance of 1,000 metres. She was due off Cape Bon at 1100 hours.
  20 Apr 1942050635° 45'N, 11° 06'EAt 0506 hours, a large steamer was sighted, followed shortly after by two smaller vessels. Since, the Italian steamer Panuco (7,751 GRT, built 1941), escorted by two destroyers [actually the destroyer Folgore, the torpedo boat Centauro and the tug Instacabile], were expected at 0320 hours, the attack was aborted.

At 2120 hours, a column of smoke was observed, apparently a vessel hit. An Italian convoy had been sighted earlier, but T.V. Gran did not know if this was the same one. Aradam made an enemy report at 2239 hours, signaling three vessels steering 090°.

  14 Nov 1942113236° 59'N, 7° 49'EAt 1132 hours, two MTBs similar to the Italian MAS 60-ton type were sighted and Aradam turned away.
  16 Nov 1942023036° 59'N, 7° 49'EAt 0230 hours, two steamers were sighted on an easterly course, 11 knots. Aradam trailed them, hoping to gain a favourable attack position, but lost them at 0344 hours in a sudden rain squall.
  16 Nov 1942044736° 52'N, 7° 52'EAt 0344 hours, under heavy rain, which had rendered the binoculars useless, a steamer was sighted at a distance of 3,000 metres, steering 210°.

At 0447 hours, the vessel altered course to starboard, offering a good attack angle. Two torpedoes (533mm, G7e type) were fired from bow tubes at a distance of 500 metres. They missed as the vessel had turned to port.

At 0506 hours, another pair of torpedoes (533mm, G7e type) were fired from bow tubes at a distance of 600 metres. They also missed. One torpedo exploded on the coast.

From 0514 to 0544 hours, Aradam opened fire on the vessel, claiming a direct hit on the bridge with the third round. However, a defective round exploded shortly after exiting the barrel, temporarily blinding the gun crew and the personnel on the bridge and the action could not be renewed.

The target has not yet been identified.

At 1930B hours, the submarine HMS P 228 (Lieutenant I.L. Mackay McGeogh, RN) was lurking near Ischia, when hydrophone effect was detected by the ASDIC operator. Shortly after, a submarine of ALAGI or perhaps GIOVANNI DA PROCIDA Class was observed , steering 047°, 13 knots.

At 2010B hours, six torpedoes were fired at 4-second firing intervals, from a distance of about 2,000 yards. They all missed. Twelve minutes later, two explosions were heard, probably torpedoes exploding at the end of their run.

This was almost certainly Aradam, who reached Naples at 2155 hours, but did not notice the attack.

At about noon, Aradam was testing her forward torpedo tubes when, due to an error in drill water flooded the submarine through tube no. 1, causing her to sink. Although T.V. Forli was not directly involved, he received a severe reprimand from an investigating commission presided by Admiral Legnani himself.
