Notes on event

At 21.51 hours on 20 September 1943 HMCS St. Croix (I 81) (LtCdr A.H. Dobson, DSC, RCNR) was hit in the stern by a Gnat from U-305 while escorting the convoy ON-202 southwest of Iceland. She sank within six minutes after being hit by a T-3 coup de grâce from the same U-boat at 22.44 hours. The next morning, five officers and 76 men were picked up from two rafts and a half sunken whaler by HMS Itchen (K 227) (LtCdr C.E. Bridgman, DSO, RNR) which also had been attacked with a Gnat by U-305 at 22.53 hours, but was missed. Only one of the rescued men survived the sinking of the frigate by U-666 (Engel) on 23 September.

HMCS St. Croix (I 81) was one of the first victims of the newly developed acoustic torpedo Gnat.
