(0) 278° - Punta Stilo - 5.5 miles.
At 1815 hours, two torpedo wakes were sighted on the starboard side. Salpa put the helm hard to port to avoid them.

This attack was made by the submarine HMS Rover (Lieutenant. Commander H.A.L. Marsham, RN). She had sighted a submarine of the PERLA class at a distance of 8,000 yards and, at 1752 hours, fired five torpedoes from a distance of 1,500 yards (a sixth misfired and Marsham believed it was the one that should have hit).

At 2300 hours, Salpa encountered a convoy (the Germans Arta, Heraklea and Maritza, all empty, on transfer from Bari to Messina) escprted by the destroyer Baleno and signalled the presence of the enemy submarine.
