Members of Thiepval's crew maintain the ship's main armament, a 12-pounder cannon mounted on a platform in the bow.

Thiepval's limited weaponry was sufficient for the ship's peacetime patrol work. After being transferred to the west coast from Halifax in 1919, Thiepval's duties included counting seals, patrolling against rum-runners, and ensuring that American fishing boats did not enter Canadian territorial waters. Years after Thiepval's 1930 sinking, divers raised this gun and placed it on display at nearby Ucluelet, British Columbia.
