Italy, probably at the end of 1940. Several officers and non-commissioned officers of the Italian Navy meet at a naval base at the invitation of the Italian Navy. Here they are told that a special operation against the Royal Navy is planned in Crete, which will require highly qualified personnel. All volunteer.
In a specially prepared training area, the volunteers train in the use of small torpedo boats and speed boats of the explosive boat type M.T. against the British. The boats carry only one torpedo. The tactic is to sneak up on the enemy ships at night and then head towards the target at top speed. Shortly before the collision, the speedboat drivers, who are wearing diving suits, are supposed to jump backwards off the boats. It is expected that the British will then rescue those who voluntarily shipwrecked. As the training officer points out, this is not a kamikaze operation.
The unit is transferred to the Greek island of Leros. But before the mission against Crete takes place, an emergency occurs. An Italian submarine is attacked and sunk by two British fighter-bombers. However, since the wreck lies in shallow waters, there is an opportunity to rescue part of the crew, who are in an area of the boat separated by bulkheads. In a highly dramatic rescue operation, the members of the commando succeed in first laying an oxygen line in the submarine and then opening a hatch so that the crew, who are extremely nervous, can finally get out of the sunken wreck and be rescued.
The command then attacks Souda Bay at night. With great difficulty it proves possible to overcome sea-mine barriers. Although they are spotted by the British guards and come under frenzied fire, the attack on the British units succeeds. The torpedo men who jumped off in time are rescued by the British and become prisoners of war.[2]
