Two merchant ships were sighted proceeding on a 270° course at 13 knots. One was described as a 10,000-ton and the other as a 1,500-ton transport. The submarine fired one torpedo (533mm) at 1,700 metres at the largest. The torpedo missed ahead. These were the British freighters Baron Erskine (3,657 GRT, built 1930) and Baron Newlands (3,628 GRT, built 1930), on passage from Oran to Bizerta, when they were recalled to Gibraltar due to the French Armistice.

Shortly after, a second torpedo (533mm) was fired from 1,400 metres at Baron Erskine. This time the torpedo missed astern.

C.C. Corvetti ordered his gun crew to open fire from 1,200 metres on Baron Erskine. The forward gun alone could be used as the aft gun crew was exposed to the heavy seas. Although many hits were claimed, only one round hit the British ship causing minor damage. Not to be outdone, Baron Erskine replied with her gun, claiming two hits from a distance of 2.5 cables (about 450 metres) but the submarine escaped damage. Corvetti wanted to fire a third torpedo, but the British ship was coming head on, intending to ram the submarine, and presented a poor target. As Baron Newland was now coming to the assistance of her sister ship and was opening fire, the Italian captain decided to take his submarine down. He thought that his victim was slowly sinking and he now attempted to fire another torpedo from periscope depth to finish her off. He could not regain contact and the two ships escaped.

(0) Between Cape Spartivento (Sardinia) and Cape Pula.
An Italian seaplane was observed flying at an altitude of 400 metres on opposite course. The plane returned on a second run to fly over the submarine from the stern. Despite the Italian flag being well displayed on the conning tower, it appeared to be threatening and the Glauco machine gun crew fired off 56 rounds before the error was recognised and the aircraft left.

  3 Aug 1940082537° 35'N, 0° 38'WThe submarine was submerged at a depth of 30 meters, when four explosions were followed by two more very close. Glauco had apparently come under air attack, but was undamaged. RAF records do not seem to show such an air attack and the aircraft may have been Italian.

On passage from Port Arthur (Texas) to Barcelona, the Spanish tanker Campero (6,382 GRT, built 1934) was stopped and her papers examined before she was allowed to proceed.
  7 Oct 1940094537° 07'N, 19° 36'WAA convoy was observed, steering 030° at 10 knots. The attack was aborted due to the indecision of C.F. Mellina (who was later dismissed from submarine command due to his lack of offensive spirit).

The Portuguese Corvo (727 GRT, built 1919), on passage from Terceira to Lisbon, was stopped and her papers examined before she was released to resume her passage.

  1 Jan 1941105056° 10'N, 19° 25'WA submarine believed to be German, was observed proceeding at 12 knots, at a distance of 5,000 metres. Glauco did not attempt to make contact and was probably not sighted as she was on the dark side of the horizon.
  5 Jan 1941174555° 35'N, 16° 00'W
(0) Position approximate.
Glauco sighted a large aircraft, flying low, at a distance of 6,000 metres and dived. This was possibly Sunderland 'A' (L5798) of 210 Squadron piloted by Flight Lieutenant R.E.G. Van der Kiste. At 1500 hours, a submarine was sighted at 1/3 of a mile. The Sunderland attacked and 45 seconds after the sighting released two 450lb depth charges from 20 feet. They were estimated to fall 100 feet ahead of the track. No results were seen, and visibility was too bad for photographs. The bottom of the hull of the Sunderland was damaged by suspected fragments from the depth charges; on alighting at Bowmore, the aircraft rapidly filled with water. Only after heavy pumping and baling was a diver able to apply a leak stopper from the outside. However, Glauco did not report any attack.
  7 Jan 19410010As the submarine was switching engines (from electric to diesel), a mistake in execution caused the door of cylinder no.2 to exploded, causing a leg injury to the rating responsible. The damage was repaired.

At 0245 hours, Glauco sighted a steamer at a distance of 3,000 metres. At 0305 hours, she fired a bow shot (533mm) from a distance of 600 metres. It missed. This was the Ocean Boarding vessel HMS Cavina (6,908 GRT, built 1924).

Glauco now opened fire with both her 100mm guns, firing ten rounds and claiming two hits. The Breda machine guns also joined in as the distance got shorter and fired 195 13.2mm rounds. The target (HMS Cavina), replied with what appeared to be two 2 cm guns and a stern gun (estimated at a 120 or 152mm calibre). The gunnery officer of the submarine (Sottotenente di vascello Carlo Marenco Di Moriondo) manning the rear gun, was killed and was posthumously awarded the Medaglia d'Oro.
  15 Jan 1941044545° 48'N, 3° 45'WA group of fishing vessels was encountered, one of which turned toward the submarine as if attempting to ram her. Glauco took evasive action.

A submarine chaser was observed at a distance of 1,000 metres. It had apparently detected the submarine, this was the armed trawler HMT Scottish joined later by HMT Loch Oskaig. Glauco went down to 130 meters but, when passing 30 meters, she was depth-charged and damaged by a first pattern of six depth-charges. A total of 130 depth charges were counted until 2230 hours, but when the submarine surfaced at 2330, she sighted nothing and escaped at high speed to the westward.
  16 Apr 19410200

The Swedish freighter Lisa (?) was sighted. She was navigating with her lights on. The submarine desisted from attack and shortly after abandoned her patrol due to the damage incurred during the depth-charge attack of 14th April.

The destroyer HMS Wishart had left a convoy at 0655 hours when Glauco was sighted at 0941 hours at a distance of 4 miles. The submarine sighted the destroyer at 5,000 metres and submerged. At 0958 hours, Wishart carried out the first of eight depth-charge attacks and, at 1220 hours, the submarine was finally forced to the surface. The destroyer opened fire with Lewis guns and two 4-inch rounds. One officer and seven ratings were killed or drowned, seven officers and forty-four ratings were picked up. Attempts to tow the submarine to Gibraltar failed. The submarine was finally sunk with gunfire and three torpedoes (they all missed!). Some documents were recovered.
