. On 16 December, she attacked Japanese boats that were preparing for the invasion of Hong Kong Island, but ran aground at Uk Kok. She was later refloated later that day and returned to Aberdeen dockyard. Further into the afternoon, she became the target of Japanese high-level bombing. A near miss caused several casualties. With the dockyard badly damaged, the damage ''Thracian'' suffered from running aground was considered too bad to fix. On the next day, she was deliberately run aground at Ngan Chau. The crew of ''Thracian'' continued to defend the colony as infantry, and would suffer heavy losses in the battle and subsequent captivity. On 24 December, Japanese troops began salvaging the ship, and she was later captured by the Imperial Japanese Army.

On 15 March 1944, she was classified as the miscellaneous ship (training ship), and renamed ''Special Training Ship No. 1''. She was used for a test bed for new weapons.
