(0) 176° - Cape Santa Maria di Leuca - 59 miles.
|At 2030 hours, a submarine was sighted at 2,000 metres, steering 170° at 1 or 2 knots.|
At 2034 hours, Serpente fired a single torpedo from a bow tube at a distance of 1,000 metres. The electric firing did not work immediately and the delay of 3 or 4 seconds was enough for the torpedo to miss the target by a few metres astern.
At 2037 hours, a second torpedo was fired from a bow tube at 800 metres.
Serpente reverted course and at 2040 hours, fired a third torpedo, this time from a stern tube. After 25-30 seconds a violent shock was felt. C.C. Tognelli was under the impression that the other submarine had dived just before it was hit and this would explain why no traces of survivors or debris were found.
In fact, the "enemy" submarine was Marcantonio Colonna of the Messina Gruppo (Serpente belonged to the Taranto Gruppo). T.V. Gozzi of Colonna had observed the attack and, as his opponent was maneuvering for a stern shot, had immediately dived. A torpedo was heard passing just above her.
Curiously, C.C. Vittorio Emanuele Tognelli and several officers and ratings' names were proposed for medals for this attack.

|At 1705 hours, Serpente was proceeding at a depth of 47 metres, when hydrophone effects were heard. During the next hours, the submarine was hunted by three destroyers and heard 39 depth charges. She escaped by going down to 110 metres.|
