38° 45'N, 15° 16'EAt 1712 hours, the lookout on the port side aft spotted a large bubble of air at a distance of 800 metres followed by three torpedo tracks. The helm was put hard to starboard and two torpedoes missed astern, the nearest at 20 metres, and the third passed under the keel near the deck gun, on a 160° angle.

At 1713 hours, a fourth torpedo was sighted and the submarine kept turning to starboard and it passed on a parallel run 60 metres to port.

The attack was made by the submarine HMS P 43 (Lt. A.C. Halliday, RN), later renamed HMS Unison. At 1658 hours, she had sighted the Italian submarine steering 267° at 12 knots. At 1710 hours, she fired a salvo of four torpedoes from a range of 1,400 yards. They missed and the target was observed to have turned northward.

6.Acciaio (AC)7 Nov 19420320Cagliari13 Nov 19421344Cagliari903Sailed for a patrol between 37°05' N and 37°15' N and between 07°30' E and 08°00' E and this was reached at 0215 hours on the 8th. During the same day, she received an order to proceed to Cape Bougaroni and patrol between 37°20' N and the coast. On 10th November, she was was ordered to patrol off Algiers between 37°00' N and the coast and between 02°40' E and 03°00' E.

(0) Position is approximate.
At 0441 hours, a warship was observed to be firing her machine-guns at an aircraft. It was believed to be an Italian submarine.
  9 Nov 1942205537° 05'N, 4° 16'EAt 2055 hours, a submarine of the DANDOLO class was sighted on an opposite course. This was possibly Axum returning from patrol.

36° 59'N, 2° 51'E
(0) 174° - 37° N, 02° E - 22 miles (Lord Lotham) or 36°38N, 02°02E.
At 0604 hours, a large warship was sighted on the starboard beam at a distance of 5,000 metres.

At 0610 hours, it was identified as a cruiser of the LEANDER class because of its single funnel and four gun turrets. The target appeared to proceed at 8 knots.

At 0617 hours, a pair of torpedoes were fired from bow tubes at a range of 1,300 metres, followed a minute later by another pair. The third torpedo passed between turret 4 and the stern but no explosion was observed although one was heard.

At 0626 hours, three depth charges were heard, followed by two more and it was believed they had been dropped by the cruiser. Acciaio was slightly damaged. More depth charges followed at 0628, 0714 and 0915 hours but the submarine succeeded in eluding her adversaries.

The target may have been the armed trawler HMT Lord Lotham (FY 113, 464 tons) escorting convoy T.E.1. She reported being missed by a torpedo at that time although the position does not match (unless there is a typographical error).

37° 22'N, 6° 14'EAt 2324 hours, the Officer of the Watch spotted an object of the horizon. Shortly after it was identified as a destroyer of the JERVIS class steering 230° at 18 knots.

At 2327 hours, a pair of torpedoes were fired from the stern tubes at a range of 2,000 metres. The submarine submerged upon firing and explosions were heard after 80 and 87 seconds. The torpedoes had actually missed.

This was the minelayer HMS Abdiel and she avoided the two torpedoes, She had just laid a minefield off Bizerta during the night of 6-7th February.
