 Hezlet was so preoccupied with these two tasks that he did not himself hear the torpedoes hit but was assured by the general jubilation in the control room that they had.An attack on "Unique" by an Italian flying boat later that day damaged one of her fuel tanks, and so Hezlet returned early from patrol.Upon his return to Malta, he learned that both "P33" and "P32" had been lost, making "Unique" the only submarine to survive the mission.
