HMHS Glenart Castle (His Majesty's Hospital Ship) was a steamship originally built as Galician in 1900 for the Union-Castle Line. She was renamed Glenart Castle in 1914, but was requisitioned for use as a British hospital ship during the First World War. On 26 February 1918, she was hit and sunk by a torpedo fired from the German U-boat .
Britain entered the First World War on 4 August 1914. The next day Galician was held up west of the Canary Islands by a ship flying a German flag. German officers boarded her, searched her papers and took two Army officer passengers prisoner before releasing her. In October 1914 she was refitted as a hospital ship and renamed Glenart Castle.
Glenart Castle subsequently suffered damaged when she struck a mine in the English Channel northwest of the Owers Lightship on 1 March 1917. Hit near the rear starboard around 23:40, the engines were stopped and the damage inspected. Th
