(0) 345° - La Galite - 39 miles or Italian Grid 4782/3.
|At 0220 hours, a cruiser and two destroyers were sighted steering 240°, 25 knots. Corallo was unable to attack them.|
|13 Dec 1942|
|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.
