On 16th June, she was ordered to area between 32°13'N and 32°27'N and 25°00'E and 25°20'E but diverted to Leros because of engine defects. Politi had been ordered to maintain the patrol at all cost and earned the disapproval of MARICOSOM. The patrol report is lost.

31° 34'N, 27° 48'EJantina's patrol report has been lost. The following is therefore not detailed as only references from signals have survived.

At 0545 hours, a destroyer of the HERO class was sighted at a single torpedo was fired. A hit was claimed but it actually missed.

This was the sloop HMAS Parramatta. She obtained an ASDIC contact, dropped ten depth charges and was then joined in the hunt by the destroyer HMAS Stuart.

At 1345 hours, Stuart obtained a contact and carried out four runs, dropping a total of 20 depth charges. Jantina suffered multiple leaks and had to abandon her patrol.

(0) 240° - Stapodia Island - 11.5 miles.
At 1946 hours, the submarine HMS Torbay was patrolling off Stapodia Island when a submarine was sighted at a distance of 4 miles, steering 255°. Initially, she was thought to be French of the DAUPHIN class. With the Campaign in Syria going full blast, she was thus considered fair game.

At 2016 hours, six torpedoes were fired from a distance of 1,500 yards. About a minute later, a loud explosion was heard followed by a tremendous double explosion, which caused minor damages to the British submarine. Because an aircraft was seen approaching, HMS Torbay went deep. This was a German aircraft flying from Rhodes to Athens who witnessed the scene.

This was Jantina. Only six men (two officers, two petty officers and two ratings) survived by swimming to the coast. Help was quickly organised. Three MAS boats and a motorboat from Syros and Samos, three seaplanes from Rhodes and Leros and one seaplane from Piraeus were directed to the scene but no other survivors were found. Four officers (including C.C. Vincenzo Politi) and thirty-eight ratings perished.
