MS Harbo Jensen var på reise fra Alexandria til Benghazi med krigsmateriell. Underveis ble skipet omdirigert til Tobruk. Harboe Jensen hadde gjort flere turer i dette farvannet og var flere ganger blitt angrepet av tyske fly. Den 15. januar 1943 ble skipet torpedert av den tyske ubåten U-617 i posisjon 3304N og 2150Ø. Skipet sank hurtig. En armert tråler fulgte skipet og satte i gang redningsaksjon, men fant bare fem nordmenn og en brite. De fem hadde hoppet over bord og fikk rettet opp en kantret livbåt. 18 mann omkom i forliset.
