At 0352 hours, five cruisers were sighted at a distance of 10,000 metres, steering 020°, 20 knots. Ascianghi could not close within attacking range.
  22 Jun 19400130
0055 (e)

(0) Near Cape San Antonio (Balearic Islands).
At 0125 hours, a darkened 15,000-ton steamer was sighted.

At 0130 hours, four torpedoes (three 533mm, one 450mm) were fired in quick succession from the bow tubes, at a range of 1,700 metres. They all missed.

This was the British Ashcrest (5,645 GRT, built 1920).

Ascianghi then opened fire, claiming hits with her second and third salvoes. The enemy vessel turned sharply to starboard and replied very accurately with its gun, immediately straddling the submarine. Ascianghi had to crash-dive and the vessel escaped.
  25 Jun 19400125
(0) Italian Grid 1422/3.
At 0125 hours, four large enemy warships were sighted, steering 180°, 22 knots. They passed out of range.
  25 Jun 19400125
(0) Near Italian Grid 1422/3.
At 0125 hours, dark shapes were sighted at a distance of 10,000 metres. Aradam closed to 8-9,000 metres and recognised four large warships believed to be cruisers. They passed out of range and the submarine made an enemy report.
  25 Jun 19400223
(0) Near Italian Grid 1422/3.
At 0223 hours, a destroyer was sighted. It was suspected to have located the submarine after she had sent an enemy report for the four warships sighted earlier. Aradam dived to 74 metres, then returned to 35 metres and used the Rovetto apparatus to remain motionless until the warship went away.
  25 Jun 19401748
(0) Near Italian Grid 1422/3.
At 1748 hours, a large tanker of the MÉKONG class was sighted at a distance of 8-9,000 metres. It was then observed to be escorted by a destroyer of the AUDACIEUX class. They passed out of range.
  26 Jun 19401625At 1625 hours, a merchant ship was sighted, but the attack was aborted when she was recognised as Greek.
  26 Jun 19401940At 1940 hours, four merchant ships, two of them Yugoslav, one Panamian and the fourth not displaying any flag but suspected to be French. The submarine proceeded to attack the latter. The attack was aborted as Ascianghi could not close the range.

Shortly after, a light cruiser of the PERTH or BERTIN class was sighted at a distance of 4-5,000 metres. Again, the target passed out of range.
  29 Jun 19401615At 1615 hours, a large submarine, probably Italian, was sighted at a distance of 7,000 metres moving away, steering 110° at 15-16 knots.

At 0605 hours, the Italian torpedo-boat Vega was met and informed Ascianghi that the points of approach to Cagliari C and E were dangerous because of suspected mines.
