| Fate: | |
| Syrtis left Lerwick on 16th March 1944 for a patrol off the Norwegian Coast in Latitude 63° 36’ North. On 20th March 1944 the Submarine was ordered to an area in the vicinity of Bödo. records indicate that she carried out attacks on enemy vessels in the area on 22nd March. Syrtis was ordered to leave her Patrol Area on 28th March 1944 but failed to return to Lerwick as expected on 30th March 1944. An air search was carried out but no sign of the Submarine was found. Mines are now known to have been laid in the area in which HMS Syrtis was working and it is almost certain that HMS Syrtis was lost with all hands by striking a mine off Bödo sometime between 22nd and 28th March 1944. | |
When American submarine Swordfish is torpedoed the survivors are picked up by a passing German U-boat but an outbreak of meningitis threatens all aboard.
