The details of this attack are not well known as Ascianghi did not return from patrol.

In the afternoon of 23rd July, the light cruiser HMS Newfoundland was torpedoed by U-407. As the stricken vessel managed to limp away to Malta, the destroyer HMS Laforey (D.19) was left behind to hunt the U-boat.

At 1428B hours, HMS Laforey had carried out an attack, believed to be on a non-sub contact. At 1440 hours, she had been joined by the destroyers HMS Faulknor (D.8), HMS Inglefield, HMS Ilex, HMS Raider and HMS Eclipse for the antisubmarine sweep.

At 1549B hours, two torpedo tracks were sighted by HMS Laforey and HMS Eclipse, apparently fired from about 3,500 yards. The two destroyers combed the tracks.

This was Ascianghi who had fired two stern torpedoes at the destroyer, mistaking her for a cruiser.

At 1550B hours, Laforey dropped a pattern of eight depth charges set from 150 to 300 feet.

At 1554B hours, Eclipse dropped a pattern of eight depth charges set at 100 feet.

At 1557B hours, Laforey dropped a second pattern of eight depth charges set from 350 to 550 feet.

At 1608B hours, Eclipse dropped a pattern of eight depth charges set from 250 to 350 feet.

At 1615B hours, Laforey dropped a third and final pattern of eight depth charges set from 150 to 385 feet. About a minute and half after this attack, Ascianghi surfaced in the wake of Laforey and was immediately engaged with gunfire by all the destroyers in the group. Laforey fired 62 4" rounds, claiming six certain hits, and 83 20mm rounds from about 800 yards. Ascianghi sank stern first at 1623 hours.

Twenty-three men perished. Twenty-seven survivors (including S.T.V. Mario Fiorini) were picked up.
