|15 May 1942||1955||33° 50'N, 22° 22'E||At 1055 hours, a destroyer steering 270° was sighted. It turned toward the submarine, forcing a crash dive.|
|15 May 1942||1955||At 1955 hours, as the submarine surfaced, a destroyer was sighted at a distance of 5,000 metres. It had not been detected by the hydrophones. It must have detected the submarine and Asteria had to crash-dive.|
From 2013 and 2053 hours, eight patterns of depth charges were heard at a regular interval of about 4 minutes.

|2||Beltrame, Pasquale||2 Jul 1942||1900||Messina||21 Jul 1942||0700||Messina||2825||Sailed escorted by the auxiliary Castiglia, which could only make 7 knots and was therefore left behind at 2000 hours on 2nd July, then patrolled between 33°40'N and 36°00'N, and between 32°00'E and the Syrian coast.|
|3 Jul 1942||0740||At 0740 hours, two aircraft were seen at a distance of 5,000 metres, flying toward Asteria who dived.|
|3 Jul 1942||0830||At 0830 hours, the Italian hospital ship Arno was sighted at a range of 10,000 metres. Asteria had been informed of her passage but the hydrophones did not detect her.|
|3 Jul 1942||0945||At 0945 hours, an aircraft was seen at a distance of 4,500 metres and the submarine dived.|
|5 Jul 1942||1355||At 1355 hours, an aircraft was seen at a distance of 4,000 metres and the submarine dived.|
|11 Jul 1942||0923||35° 17'N, 35° 28'E||At 0923 hours, a smoke was sighted on the horizon at a range of 14,000 metres. It turned out to be a patrol vessel, zigzagging, steering 320°, 16 knots and followed at a distance by two steamers. At 0955 hours, Asteria closed to a distance of 5,000 meters of the escort and at 1000 hours was still 9,500 meters from the steamers before breaking off the chase.|
|11 Jul 1942||1025||35° 16'N, 35° 24'E||At 1025 hours, a steamer was sighted at a range of 6,000 metres. An escort was also sighted at 1,000 meters. The submarine attempted to close the steamer before losing contact at 1110 hours.|
|14 Jul 1942||0208||33° 48'N, 34° 56'E||At 0205 hours, the mist on the horizon made it difficult to identify an indistinct shape sighted at a range of 1,500 metres. Asteria steered toward it and recognised it as a large destroyer.|
At 0208 hours, a single torpedo (533mm, S.I. 270 type with S.I.C. pistol) was fired at a range of 2,000 metres. The destroyer altered course to port, presenting her stern.
At 0210.5 hours, a single torpedo (533mm, S.I. 270 type with S.I.C. pistol) was fired at a range of 2,500 metres. An explosion was heard after 151 seconds but the destroyer had disappeared in the dark side of the horizon. Both torpedoes apparently missed.
This was possibly the armed whaler HMSAS Protea, detached to assist the Dutch tanker Odinda who had just been torpedoed by U-371. Other warships in the general vicinity were the corvette HMS Gloxinia and the escort destroyers HMS Croome and HMS Tetcott. No attack appears to have been reported.
|14 Jul 1942||2245|
|33° 52'N, 34° 26'E||At 2245 hours, a submarine was sighted at a range of 1,000 metres and believed to be Italian. Prudently, Asteria turned to starboard at maximum speed to move away.|
This was actually HMS Turbulent (Commander J.W. Linton, DSC, RN) who, at about the same time, sighted a submarine for only about 50 seconds, before she dived and lost contact.

|14 Aug 1942||2056||35° 33'N, 13° 53'E||At 2056 hours, an aircraft was seen and Asteria dived. The submarine was at a depth of 29 meters when four groups of bombs (three or four each) were heard, but she escaped damage.|
The aircraft has not been identified.

It was a false alarm and she was recalled at 2030 hours on the 30th. Uneventful.|
|30 Oct 1942||0850||At 0850 hours, a German aircraft was sighted and exchanged recognition signals.|
|7||Morrone, Dante||7 Nov 1942||0310||Cagliari||19 Nov 1942||1210||Cagliari||1406||Sailed for a patrol between 37°30'N and 37°40'N, and between 07°30'E and 08°00'E. She was then ordered to 37°10'N, 03°25'E (off Algiers). On 11th November, she was ordered to an area between 38°00'N and 38°20'N, and between 06°40'E and 07°00'E. On 13th November, she executed a reconnaissance of Bougie.|
|8 Nov 1942||0330||37° 35'N, 7° 56'E||At 0330 hours, a submarine was sighted on a westerly course. Asteria turned away.|

|9 Nov 1942||2052||37° 12'N, 4° 18'E||At 2052 hours, a submarine was sighted on a westerly course.|
|11 Nov 1942||2052||At 2052 hours, two German aircraft were seen. One of them flashed recognition signals. Asteria could not respond as none of her signal flares worked.|
|13 Nov 1942||0203|
|36° 46'N, 5° 08'E|
(0) 050° - Cape Carbon - 3 miles (HMS Pentstemon).
|At 0154 hours, a vessel was sighted in poor visibility, followed by a second vessel at 0200 hours and both appeared to be flashing signals.|
At 0203 hours, a pair of torpedoes were fired aimed at the first vessel, believed to be a corvette or a torpedo boat. The torpedoes missed, probably due to their very visible phosphorescence. Two minutes later, the second vessel appeared to turn toward the submarine and Asteria dived to 90-100 metres. Two explosions shook the submarine at 0210 hours. Note: The Asteria report gives the position as 36°36' N but this is a typographical error, it also gives the position as 090° - Cape Bouak - 2 miles).
The target was the corvette HMS Pentstemon which reported missed by a torpedo.
|13 Nov 1942||0708|
(0) Near Cape Carbon.
|At 0708 hours, Asteria was proceeding on the surface toward her patrol area, when three aircraft where sighted. She crash-dived. She surfaced again at noon.|
|13 Nov 1942||1245|
|37° 13'N, 5° 54'E||At 1245 hours, a Hudson bomber was suddenly sighted flying at a height of 30 metres, attacking from the stern. There was no time to dive and Asteria barely had time to open fire with her machine-guns, letting off 25 13.2mm rounds, claiming the aircraft certainly hit. The aircraft dropped two A/S bombs and three depth charges. One of the A/S bomb exploded on the port side very close to the deck gun. Fortunately, there were no casualties and only minor damages to the superstructures. At 1247 hours, the submarine crash-dived.|
The aircraft was Hudson 'C' of 500 Squadron, piloted by Sergeant W.M. Young. It sighted a submarine at a distance of 12 miles, steering 320° and dived to the attack from the port quarter. It strafed and dropped four depth charges which straddled the submarine forward of the conning tower. The U-boat was reported to have put up light antiaircraft fire and the bomber was not hit. After the explosions, the submarine was no longer seen but there were no debris or oil patch. After 5 minutes, an underwater explosion was observed but again without debris or any oil coming to the surface.
|16 Nov 1942||0120|
(0) Off Bougie.
|At 0120 hours, the submarine made a reconnaissance of the Bay of Bougie. According to her survivors, the submarine ran aground. However, her patrol report showed she followed the coast at a depth of 7-8 meters and, if she did ran aground, she managed to disengage herself.|
|8||Morrone, Dante||24 Nov 1942||1643||Cagliari||6 Dec 1942||1045||Cagliari||1068||She sailed for a patrol between 37°00'N and 37°20'N, and between 07°20'E and 07°40'E. On 26th November, she was ordered to an area between 37°20'N and the Algerian coast and between 02°40'E and 03°00'E. On 1st December, she was ordered to an area between 37°20'N and the Algerian coast, between 06°20'E and 06°40'E. Rammed and depth-charged by the minesweeper HMS Cadmus at 1830th on 4th December, but escaped.|
|28 Nov 1942||0302||37° 27'N, 4° 19'E||At 0302 hours, two transports of 5-10000-ton and a destroyer were sighted, steering 270°, 13 knots. They passed out of range.|
|29 Nov 1942||0400||36° 52'N, 2° 52'E||At 0400 hours, in poor visibilty, a warship was sighted at a distance of 4,000 metres, steering 090°, 10 knots. At 0425 hours, it was recognised as a JAVELIN class destroyer and shortly after, it altered course to 300°.|
At 0435 hours, two destroyers of unknown type were sighted at 2,500 and 2,000 metres respectively.
At 0437 hours, the attack on the first destroyer was aborted and Asteria withdrew on the surface. At 0448 hours, the destroyers appeared to be catching up and she crash-dived. She reached a depth of 80 metres.
At 0509 hours, fifteen depth charges exploded near the submarine.
At 0531 hours, another ten depth charges exploded in the vicinity and Asteria moved away and finally surfaced at 1755 hours.
|30 Nov 1942||0055||37° 18'N, 2° 55'E||A submarine was sighted ahead, steering 280°. Asteria turned away.|
|30 Nov 1942||0540||37° 17'N, 2° 53'E||A submarine was sighted ahead, steering 360°. Asteria turned away.|

This was Hudson 'C' of 500 Squadron, piloted by Squadron Leader Ensor, on convoy escort duty. It had sighted the submarine at distance of 5 miles. This was 20 miles from the convoy. Four Mark XI Torpex depth charges were released on the submarine from a height of 40 feet. It remained in the vicinity for 40 minutes after the submarine had dived.
