Unbeaten was recalled to Malta from her 3rd patrol, entering harbour on Friday the 27th of June 1941. The submarine and her crew would remain alongside for the next 10 days. This gave the men time to re-store, fix any outstanding defects and more importantly have some well-earned rest and relaxation. This was easier said than done on an island which was on the receiving end of one of the most concentrated bombing campaigns in World War II. Soon it was time for the submarine and her rested crew to leave Malta and embark on their 4th patrol. After sailing, and later that night, the lookouts on-board N93 witnessed a British fighter aircraft shoot down and enemy bomber. The burning aircraft thundered into the sea in a minefield area just over 10 nm from Unbeaten. The impact must have been hard as the patrol log says, ‘it was decided not to close the crash area as it appeared there would be no survivors’.
