At 0240 hours, H.2 reported sighting a torpedo track which missed her a few metres ahead. No Allied submarine operated in area at the time, so the "torpedo" was probably a porpoise .

Note: Topazio reported receiving the signal on 9th March, which means that the transfer dates of Topazio or H.2 may be incorrect.

This was almost certainly HMS Turbulent (Cdr. J.W. Linton, DSO, RN) who did not notice the Italian submarine.
