1Sposito, Leo5 Aug 19422106Cagliari15 Aug 19420845Cagliari700,5Patrolled north coast of Tunisia, between 37°20'N and 37°50'N, and between 09°40'E and 10°00'E, with Velella in an adjacent area to intercept enemy convoy.
  12 Aug 1942123837° 22'N, 9° 55'EAt 1238 hours, Granito went down to 45 metres for a hydrophone watch, after listening to radio communications. Noises from two vessels were picked up and she was returning to periscope depth when at a depth of 20 metres she was suddenly depth charged. Because of the flat sea, T.V. Leo Sposito assumed he had been previously seen and brought his submarine down to 60 metres and shut the electric motors. At 1453 hours, the ASDIC pings were heard and again at 1620 hours. Granito went down to 96 metres before retuning to 60 metres.

At 1838 hours, depth charges were heard and continued until 2130 hours with a total of 301 counted [note: these most certainly included bombs on the convoy which was under air attack].

37° 15'N, 9° 40'EAt 0434 hours, information was received of a naval force reported off Cape Bon at 0143 hours.

At 0447 hours, three shapes were observed moving westward, the two closest were at a distance of about 4,000 metres.

At 0451 hours, at a range of slightly less than 2,000 metres, T.V. Sposito ordered the firing of two bow torpedoes (533mm), but only one left the tube as the bow cap of the other other tube had not been opened in time. The torpedo was aimed at a target believed to be a battleship, but missed. Four destroyers could now be seen on the starboard flank. The target was the light cruiser HMS Kenya.

At 0452 hours, a pair of torpedoes were fired at a second target, believed to be a cruiser of the LONDON class. One explosion was heard.

The target was the destroyer HMS Ashanti and she was missed.

At 0453 hours, the submarine had turned to fire a pair of stern torpedoes aimed at the first target and dived upon firing. After 60 seconds two explosions were heard, leading Sposito to believe that both torpedoes had hit.

HMS Kenya was actually missed and attempted to ram the submarine but Granito was inside her turning circle and dived before any attempt could be completed.

Despite the hits claimed, the Italian High Command concluded that the attacks missed as two cruisers had been located in this area by air reconnaissance, one FIJI and the other of the DIDO class and both appeared undamaged. Later, when they reached Gibraltar, it was reported that the FIJI class had been hit in the bow.

At 0900 hours, an Italian tanker was sighted on a northerly course [this was Perseo proceeding from Tunisia to Cagliari].

At 0915 hours, two torpedo hits were heard and a long column of smoke was sighted and it was assumed that the tanker had been hit [she had been torpedoed by HMS P 211].
