MEDITERRANEAN 1942

 

Another of the unnamed submarines completed in May 1941 and deployed in the Mediterranean where she arrived to join the 10th Submarine Flotilla in June 1941.

 

In an early patrol she sank the Italian mercantile BARBIAGO off Pantellaria which was part of a five ship convoy escorted by three destroyers and three torpedo boats. Although under heavy depth charge attacks by the escort, the submarine was able to escape. Later on 12th August she was deployed to join HM Submarines P32 and UNIQUE to intercept an Italian troop convoy on passage to Tripoli. Whilst patrolling west of Tripoli she came under attack by anti-submarine vessels after which no contact could be made. It is not clear whether this submarine sank in these attacks which lasted two hours or whether she struck a mine in the defensive minefields laid off the port.
