31 May 1943 as escort of the Italian merchants Postumia (595 GRT) and
Vragnizza (1592 GRT) heading for Messina. Around 0140 hours on 2 June
1943 while off Cape Spartivento this convoy was attacked with gunfire by
the British destroyer HMS Jervis (Capt. J.S. Crawford, DSO, RN) and the
Greek destroyer Vasilissa Olga (Lt.Cdr. G.

Vasilissa Olga were assisted by allied
aircraft that illuminated the targets by firing flares.
