  17 Jan 19431902
1923 (e)
37° 20'N, 6° 20'EAt 1902 hours, the lookout aft spotted an aircraft coming from the south. Although it could have been a Junker 88, T.V. Girola ordered the submarine to crash-dive.

At 1910 hours, Nichelio surfaced and proceeded northward.

At 1918 hours, an aircraft was sighted on the port bow at a distance, making directly for the submarine. There was no time to crash-dive and Girola ordered the machine guns manned and they opened fire at a range of 1,000 metres. The aircraft was identified as of the Armstrong Whitworth [Whitley] type.

At 1919 hours, it flew over at a height of 30-40 metres and dropped five bombs. One fell 20 metres off the starboard bow, bomb fragments hit the submarine, causing a leak forward which prevented diving. The aircraft was observed to fire back at the submarine with its stern gun.

At 1922 hours, the aircraft flew over the submarine at a height of 2,000 metres without dropping a bomb.

At 1955 hours, the aircraft attempted a surprise attack, dropping a single bomb which fell 50 metres from the port beam.

At 2005 hours, it flew at a height of 50 metres and, reaching 100 metres on the port side,it strafed the submarine. Fire was returned with the twin Breda machine-guns aft. The submarine could not used the deck gun due to the poor condition of the ammunition.

At 2020 hours, the leak forward had been plugged and the submarine dived and gradually reached 100 metres to test her water tightness.

At 0223 hours on the 18th, she received the order to return to base.

The aircraft was Hudson 'J' of 500 Squadron piloted by Flight Lieutenant H.G. Holmes. It had detected the submarine by radar, at a range of 5 miles, attacking by taking advantage of the moonlight. It had actually dropped three depth charges, which overshot the target on the first run. One 250-lb G.P. bomb was released from 1,600 feet on the second run and missed the starboard bow by 20 feet. The bomber had also strafed Nichelio, who replied inaccurately on the first run, using both cannon and machine-guns, but her aim became more accurate afterward, although the aircraft was not hit.

The submarine was actually hit by three depth-charges, one of which was found imbedded in the bow after her return to Cagliari; the other two did not explode. The A/S bomb also caused some damage requiring the submarine to return to Naples for repairs, which would take nearly a month.

1349 (e)
38° 02'N, 6° 29'EAt 1355 hours, an aircraft was sighted at a high altitude. It dived on the submarine, releasing a single bomb, which missed by 300 metres ahead. It was identified as of the Armstrong Whitworth [Whitley] type. Nichelio submerged at 1356 hours and, two minutes later, at a depth of 80 meters, she was shaken by three depth charges without incurring damage.

The aircraft was Hudson 'K' of 608 Squadron piloted by Lieutenant E.U. Johansen. It followed up the earlier attack by the 500 Squadron Hudson and sighted a surfacing U-boat of the GEMMA class at 1345 hours. The attack was made with an A/S bomb which exploded 100-150 yards ahead of the sub. The submarine immediately dived The Hudson followed up by releasing a stick of depth charges, without observing results. It released a smoke float and stayed on the scene observing until a later attack by Wellington 'S' of 150 Squadron.
  18 Jan 1943235538° 20'N, 6° 38'EAt 2355 hours, an aircraft was seen at a distance of 3,000 metres. Nichelio was ready to open fire, when the aircraft turned away at a distance of 2,000 meters and the submarine dived immediately.
  19 Jan 1943081438° 48'N, 7° 21'EAt 0814 hours, an aircraft was seen at a distance of 8,000 metres and the submarine dived.
  19 Jan 1943110038° 48'N, 7° 30'EAt 1100 hours, an aircraft was seen at a distance of 6,000 metres and the submarine dived.

2239 (e)
37° 55'N, 15° 36'EAt 2220 hours, Nichelio had just surfaced when she sighted three small vessels previously detected with the hydrophones. Initially, it was believed that they were German or Italian F-lighters, as several had been seen in the Strait of Messina. The submarine made a recognition signals as soon as the machine gun crews had joined their action stations. The three vessels opened fire and the submarine immediately replied first with the aft twin Breda and followed shortly by the forward machine gun. Nichelio had a few superficial holes to the conning tower but no casualties. It claimed to have hit one of the enemy vessel before submerging.

These were MGB-646, MGB-643 and MGB-641 of the 19th MGB Flotilla and they attacked the submarine with six pounders and oerlikons. Some sources have mentioned that MGB-641 was sunk by the submarine. It is doubtful that Nichelio's machine guns could have inflicted lethal damage to an MGB. It appears that MGB-641 was sunk shortly after by Italian coastal batteries. Most of the crew swam ashore and were taken prisoner.

At 0735 hours, four medium-sized merchant vessels escorted by four antisubmarine craft were sighted at a distance of 10,000 metres. The submarine attempted to intercept, but could not gain a favourable position and at 0910 hours, gave up the attack.

From 1025 to 1215 hours, Nichelio was hunted by three corvettes.
  17 Jul 1943140236° 42'N, 15° 24'EAt 1402 hours, a steamer was sighted on a southerly course. The submarine could not get into a favourable position and, at 1545 hours, abandoned the attack. During the chase, another steamer was also sighted on a southerly course but there was no chance to intercept it.

At 1902 hours, the lookout aft spotted an aircraft coming from the south. Although it could have been a Junker 88, T.V. Girola ordered the submarine to crash-dive.

At 1910 hours, Nichelio surfaced and proceeded northward.

At 1918 hours, an aircraft was sighted on the port bow at a distance, making directly for the submarine. There was no time to crash-dive and Girola ordered the machine guns manned and they opened fire at a range of 1,000 metres. The aircraft was identified as of the Armstrong Whitworth [Whitley] type.

At 1919 hours, it flew over at a height of 30-40 metres and dropped five bombs. One fell 20 metres off the starboard bow, bomb fragments hit the submarine, causing a leak forward which prevented diving. The aircraft was observed to fire back at the submarine with its stern gun.

At 1922 hours, the aircraft flew over the submarine at a height of 2,000 metres without dropping a bomb.

At 1955 hours, the aircraft attempted a surprise attack, dropping a single bomb which fell 50 metres from the port beam.

At 2005 hours, it flew at a height of 50 metres and, reaching 100 metres on the port side,it strafed the submarine. Fire was returned with the twin Breda machine-guns aft. The submarine could not used the deck gun due to the poor condition of the ammunition.

At 2020 hours, the leak forward had been plugged and the submarine dived and gradually reached 100 metres to test her water tightness.

At 0223 hours on the 18th, she received the order to return to base.

The aircraft was Hudson 'J' of 500 Squadron piloted by Flight Lieutenant H.G. Holmes. It had detected the submarine by radar, at a range of 5 miles, attacking by taking advantage of the moonlight. It had actually dropped three depth charges, which overshot the target on the first run. One 250-lb G.P. bomb was released from 1,600 feet on the second run and missed the starboard bow by 20 feet. The bomber had also strafed Nichelio, who replied inaccurately on the first run, using both cannon and machine-guns, but her aim became more accurate afterward, although the aircraft was not hit.

The submarine was actually hit by three depth-charges, one of which was found imbedded in the bow after her return to Cagliari; the other two did not explode. The A/S bomb also caused some damage requiring the submarine to return to Naples for repairs, which would take nearly a month.

At 1355 hours, an aircraft was sighted at a high altitude. It dived on the submarine, releasing a single bomb, which missed by 300 metres ahead. It was identified as of the Armstrong Whitworth [Whitley] type. Nichelio submerged at 1356 hours and, two minutes later, at a depth of 80 meters, she was shaken by three depth charges without incurring damage.

The aircraft was Hudson 'K' of 608 Squadron piloted by Lieutenant E.U. Johansen. It followed up the earlier attack by the 500 Squadron Hudson and sighted a surfacing U-boat of the GEMMA class at 1345 hours. The attack was made with an A/S bomb which exploded 100-150 yards ahead of the sub. The submarine immediately dived The Hudson followed up by releasing a stick of depth charges, without observing results. It released a smoke float and stayed on the scene observing until a later attack by Wellington 'S' of 150 Squadron.

At 2220 hours, Nichelio had just surfaced when she sighted three small vessels previously detected with the hydrophones. Initially, it was believed that they were German or Italian F-lighters, as several had been seen in the Strait of Messina. The submarine made a recognition signals as soon as the machine gun crews had joined their action stations. The three vessels opened fire and the submarine immediately replied first with the aft twin Breda and followed shortly by the forward machine gun. Nichelio had a few superficial holes to the conning tower but no casualties. It claimed to have hit one of the enemy vessel before submerging.

These were MGB-646, MGB-643 and MGB-641 of the 19th MGB Flotilla and they attacked the submarine with six pounders and oerlikons. Some sources have mentioned that MGB-641 was sunk by the submarine. It is doubtful that Nichelio's machine guns could have inflicted lethal damage to an MGB. It appears that MGB-641 was sunk shortly after by Italian coastal batteries. Most of the crew swam ashore and were taken prisoner.
