HMY Alexandra was a steamship built as a British royal yacht, completed in 1908. Normally transporting Britain's royal family to European ports, Alexandra served as a hospital ship during the First World War. After 17 years of British service, she was sold to Norwegian commercial interests in 1925. Renamed Prins Olav, she was first used as a luxury cruise ship on trips to the North Cape, she was converted to take more passengers and cargo. In 1937 she began sailing as a Hurtigruten passenger/cargo ship along the coast of Norway. After being requisitioned by the Norwegian government following the 9 April 1940 German invasion of Norway, she transported troops for the Norwegian war effort. Prins Olav was sunk by German bombers on 9 June 1940, while attempting to escape to the United Kingdom as the Norwegian Campaign was coming to an end.
