From the 47 Squadron Reports for February, 1944.
On February 1, four aircraft lead by F/Sgt Thomas on offensive sweep Central Aegean, scored cannon hits on a boom vessel at Stampalia (Astypalea) causing an explosion and further cannon attacks were made and hits obtained on a 150 ton caique in Amorgos and on caiques of 150, 60 and 50 tons in Naxia. 2 masts seen from sunken caique in Amorgos confirming attack by 47 sqdn on 26th January, 1944.
2nd February: Crews on stand-by, but no operations.
The Leda was a ship listed at 4573 Gross Registered Tonnage (GRT) and was escorted by 3 German torpedo boats TA-14, TA-15, TA-16. Here is a photo of the Italian ship Turbine which the Germans operated as TA-14.

As mentioned, the Leda was sunk (and TA-14 was damaged) on 2 February in an attack NE of Amorgos.
So...... It appears the attacking squadron is still a mystery and the search still is on.
