This patrol, which was to be her last, was off the coast of Libya and she was then to proceed to Alexandria. (Possibly) Became the first 'T' class sunk in Med 38'16N-17'37E - 'overdue, presumed lost'. Recent research suggests Triad was sunk by the gunfire of Italian Balilla-class submarine Enrico Toti on the 15th October, rather than Rainbow as was believed for many years. It also suggests her patrol area was off the coast of Calabria in the Ionian Sea and not Libya.
