  4 Sep 19401115
(0) Approximately 60 miles south of Crete.
At 1115 hours, Corallo was at a depth of 40 metres when she reported being attacked with fourteen bombs by an aircraft. She was undamaged, but went down to 70 metres to escape.
  13 Sep 19400812
(0) Approximately 60 miles south of Crete.
At 0812 hours, Corallo was at a depth of 40 metres when she reported being attacked repeatedly by aircraft until 1640 hours. She was undamaged, but went down to 70-75 metres to escape.
  17 Sep 19401830
1940 (e)
33° 34'N, 25° 34'EAt 1750 hours, Corallo was steering 135° at a depth of 50 metres, when her hydrophones picked up noises.

At 1800 hours, the submarine had come up to periscope depth to observe, at a distance of 7,000 metres, an aircraft carrier of the ILLUSTRIOUS class, a KENT class cruiser and seven destroyers steering 183°, 16 knots.

At 1830 hours, a pair of torpedoes (533mm, W - H type) were fired at 5-second interval from bow tubes, at range of 1,500 metres. The submarine went to a depth of 80 metres and stopped all engines. After 75 seconds, two explosions were heard, which were attributed more to depth-charges than torpedo hits. The submarine went further down, reaching a depth of 120 metres when 40 depth charges exploded, some very close. It was believed Corallo eventually reached a depth of over 140 metres. The precision of the counter-attack led C.C. Albanese to believe that the enemy destroyers were equipped with sonar.

These were indeed HMS Illustrious with the battleship HMS Valiant, the light cruisers HMS Liverpool and HMS Gloucester, escorted by five destroyers including HMS Hasty. HMS Kent had actually been torpedoed by an Italian bomber and was being escorted to Alexandria by another group of ships. The torpedoes had missed the destroyer HMS Hasty and she had immediately turned to the attack.

Corallo had been damaged by the depth-charges and began surfacing at about 2100 hours. By a freak accident, the air pressure forced the hatch opened at a depth of 10-15 metres, ejecting the First Officer T.V. Alfredo GATTI and he was never found. A rating shot himself after the depth-charging.

Perhaps unjustly, C.C. Albanese received a severe reprimand from Admiral Falangola (Head of MARICOSOM) for his actions during the severe depth charging, although his courage was never questioned.

(0) Western Med.
At 1320 hours, fifteen planes flying in an easterly direction, were sighted at a distance of 4,000 metres. These were probably Hurricanes flown off from HMS Ark Royal and HMS Victorious for Malta (operation TRACER). Corallo reported the sighting.

(0) Probably near Baleares.
At 1610 hours, a submarine similar to Sirena, was sighted at a range of 6,000 metres [Admiral Falangola wrote in his assessment that the submarine was certainly enemy]. This may have been Diaspro, but she did not report any incident. This could not have been HMS P 33 proceeding from Gibraltar to Malta as she was already east of Sardinia at the time.

At 1257 hours, the submarine HMS Unique (Lieutenant A.F. Collett, RN) had just come to periscope depth, when a submarine of the DURBO class was sighted bearing 310°, steering 185°, apparently exercising with a GENERALE class destroyer. This was almost certainly Corallo exercising at the time with the torpedo-boat Cascino.

The British submarine was unable to gain an attacking position and was thwarted by the presence of the destroyer.

It was believed to be the Italian liners Giulio Cesare (21,900 GRT, built 1921) and Duilio (23,635 GRT, built 1934). They had been given a safe conduct to go to Gibraltar for the repatriation of Italians colonists from East Africa.

At 0500A hours, the sloop HMS Enchantress, sighted three torpedoes on the port bow and she turned to port to comb the tracks. She had been escorting convoy E.T.5.P. with the Canadian corvette HMCS Baddeck. The torpedoes missed astern, the nearest by only 6 feet!

The attack had been made by Corallo.

At the same time, HMS Enchantress was turning, a radar contact was made at 1,000 yards. It was from a U-boat surfacing. Corallo was moving away at 10 knots and fired two stern torpedoes. They also missed by less than 10 feet.

At 0504 hours, HMS Enchantress had increased speed and rammed the submarine. She also dropped a depth charge set at depth of 50 feet. Corallo appeared to have gone deep.

At 0506 hours, a second run was made with six depth charges set at depths of 350 and 550 feet. At 0525 hours, this was followed by another pattern of 7 depth charges at the same depths and a final one at 0538 hours with 3 depth charges at 550 feet.

An unexplained explosion had been heard and felt at 0529 hours. It is believed that Corallo was lost in this attack, as she disappeared with all hands. T.V. Guido Guidi, five officers and forty-five ratings perished.
