HMS "Crusader" by A.E. Langsford
Death by fire - Death by ice. These were the twin threats confronting the seamen on the North Atlantic convoys: fire from the Luftwaffe's bombs, and from the torpedoes of the lurking U-Boats: ice in the deadly cold waters that could kill in three minutes, five minutes at most. Between these two hells lived another threat: the slow paralyzing hand of fear.
