  1 Jul 19400458
(0) 30 miles SW of Pantelleria.
At 0455 hours, a shadow was sighted, which appeared to be a submarine very similar to Fieramosca. At 0458 hours, one torpedo (533mm) was fired from a bow tube at an estimated distance of 1,600 metres. It missed. This was probably HMS Proteus (Lt. Cdr. R.T. Gordon-Duff, RN), which had left her patrol south of Malta and was on her way to Oran to participate in Operation CATAPULT, but she did not observe the attack.
  1 Jul 19400500

CommanderDateTimePositionDescription
Guido D'Alterio1 Jul 19400458(o) 30 miles SW of Pantelleria.At 0455 hours, a shadow was sighted, which appeared to be a submarine very similar to Fieramosca. At 0458 hours, one torpedo (533mm) was fired from a bow tube at an estimated distance of 1,600 metres. It missed. This was probably HMS Proteus (Lt. Cdr. R.T. Gordon-Duff, RN), which had left her patrol south of Malta and was on her way to Oran to participate in Operation CATAPULT, but she did not observe the attack.
Guido D'Alterio1 Jul 19400500(o) 30 miles SW of Pantelleria.A second torpedo (533mm) was fired from a bow tube at a distance of 1,400 metres but again it missed.
