HMS Thunderbolt

14 March 1943

Depth charged off Sicily by Italian CVT Cicogna

At 2210 on Friday 12th March the Italian merchant ship Esterel was torpedoed two miles north of Capo San Vito. Following the attack the torpedo boat Libra was ordered to seek out the submarine responsible - HMS Thunderbolt. The Libra made contact with the Thunderbolt that night and carried out seven depth charge attacks with no result. On Sunday 14th March the Italian corvette Cicogna obtained a contact and shortly after 0734 a periscope was sighted 2000 yards off the corvette’s bow. At 0845 the periscope was again sighted, this time less than 10 feet away. Depth charges were launched at once and the corvette increased it speed and turned for another attack when an explosion lifted the submarine’s stern out of the sea at an angle of 90 degrees. The submarine sank through a discharge of air and oil. A further two depth charges were dropped resulting in air bubbles, oil and smoke appearing on the surface were the submarine had sunk. The Cicogna remained on station for an hour but no further contact was made.

HMS Turbulent

14 March 1943

Possibly mined off Corsica or Sardinia

On 23rd February 1943 HMS Turbulent sailed from Algiers for a patrol in the Tyrrhenian Sea. On 1st March she attacked and sank the Italian steam ship Vincenz. On the 11th she is known to have attacked the mail ship Mafalda. The following morning the anti-submarine trawler Teti II sighted the periscope and conning tower of a submarine and attacked, it is believed, without success. Turbulent did not respond to any further messages and did not return when expected on 23rd March. It is thought that Turbulent fell victim to a mine off Maddalena, Sardinia and the discovery of her wreck in this area has given credence to this theory.
