The vessel that Dermot commanded, HMCS Valleyfield, was ordered in October 1941 as part of the 1942-1943 River-
class building program and was named for Salaberry-de-Valleyfield, Quebec. Laid down on November 30, 1942, by
Morton Engineering and Dry Dock Co. at Quebec City and launched July 17, 1943, the ship was commissioned into the
RCN on December 7, 1943 at Quebec City.
On May 7, 1944, the Royal Canadian Navy (RCN) frigate HMCS Valleyfield was torpedoed and sunk by the German
submarine U-548 approximately 50 nautical miles southeast of Cape Race, Newfoundland. While returning to St.
John's as a convoy escort, the ship was struck in the port-side boiler room by a GNAT acoustic torpedo, causing it to
break in two and sink in just 4 minutes. Because the vessel went down so rapidly, no distress signal was sent, which
tragically delayed rescue efforts by the HMCS Giffard.
The sinking resulted in the deaths of 125 crew members, making Valleyfield the only River-class frigate lost by the
RCN during the Second World War. Although 43 men were initially pulled from the frigid North Atlantic waters, five
later succumbed to hypothermia, leaving only 38 survivors.
There were 12 other casualties with ties to Nova Scotia lost with the sinking of HMCS Valleyfield.
The lost crew members are also honoured at a dedicated monument in Salaberry-de-Valleyfield, Quebec.
