Launched in 1917 at Kingston, Thiepval was in commission between July 24, 1918 and March 19, 1920, when she was turned over to the Department of Marine and Fisheries as a patrol vessel. Taken back into the RCN, she was commissioned April 2, 1923, for service on the west coast. In February, 1924, she was detailed to proceed across the north Pacific to Hakodate, Japan, to deposit fuel and lube "dumps" for the round-the-world flight of Maj. Stuart MacLaren. Travelling over 11,000 miles in the process, Thiepval also salvaged what remained of the aircraft after it was wrecked at Nikolski, USSR, on August 3. The trawler herself was wrecked on an uncharted rock in Barkley Sound, B.C., on February 27, 1930.
