37° 55'N, 15° 36'EAt 2220 hours, Nichelio had just surfaced when she sighted three small vessels previously detected with the hydrophones. Initially, it was believed that they were German or Italian F-lighters, as several had been seen in the Strait of Messina. The submarine made a recognition signals as soon as the machine gun crews had joined their action stations. The three vessels opened fire and the submarine immediately replied first with the aft twin Breda and followed shortly by the forward machine gun. Nichelio had a few superficial holes to the conning tower but no casualties. It claimed to have hit one of the enemy vessel before submerging.

These were MGB-646, MGB-643 and MGB-641 of the 19th MGB Flotilla and they attacked the submarine with six pounders and oerlikons. Some sources have mentioned that MGB-641 was sunk by the submarine. It is doubtful that Nichelio's machine guns could have inflicted lethal damage to an MGB. It appears that MGB-641 was sunk shortly after by Italian coastal batteries. Most of the crew swam ashore and were taken prisoner.

At 0410 hours, two torpedoes (533mm, G7e type) were fired at a range of 1,200 metres at the vessels observed to be on course 326° at 16 knots. Both torpedoes were seen to porpoise and deviate sharply to the right. They missed.

The result has not been confirmed.

The submarine sighted an explosion followed at 1107 hours by another at distance of 200 meters. The escorting destroyer, Grecale, signalled that they were under air attack but these were actually premature explosions from torpedoes fired by U-616 (OL Siegfried Koitschka). The Italians vessels were unaware that they had been under attack from a U-boat and for security reasons were diverted to Algiers.
