Italian Submarines

A heavy detonation was heard after 40 seconds run time, but there was no other confirmation. This was the only action initiated by Ginocchio in World War II.

3 April 1941 MICCA, now under command of CC Guido d'Alterio, reported one ship sunk and another damaged in a torpedo attack. There was no confirmation of either and this was the only action initiated by d'Alterio in World War II.
