High Quality Content by WIKIPEDIA articles! HMCS Thiepval was one of twelve Battle class Naval trawlers used by the Royal Canadian Navy (RCN). After seeing service on Canada`s east coast at the end of the First World War, Thiepval was transferred to the west coast, where she spent the remainder of her career. In 1924, Thiepval visited the Soviet Union and Japan as part of the support efforts for a round-the-world flight attempt. Thiepval struck a rock and sank off the British Columbia coast in 1930, and her wreck has since become a popular attraction for divers.
