On December 21, 1944, U-806 sank a merchant
vessel in the approaches to Halifax Harbour. HMCS CLAYOQUOT
was searching for this U-boat in company of HMCS TRANSCONA
and HMCS KIRKLAND LAKE on December 24, 1944 when she was
struck aft by a torpedo from U-806. She went down in less
than 10 minutes, however 73 of the 81 man crew escaped by
life raft and were picked up by HMCS FENNEL shortly thereafter.
The exact location of HMCS CLAYOQUOT remained a mystery
until 1994 when, what were thought to be her remains were
detected by members of the Geological Survey of Canada while
field testing side scan sonar equipment, 13 miles of off
Chebucto Head. HMCS CLAYOQUOT was positively identified in
September of 1996 when HMCS CORMORANT's manned submersible
dove to the site. On board was retired petty officer
Ernie White, a survivor of the sinking, who confirmed the
identity of the vessel. (Above text from Martime Museum of the
