In 1915 she was built for the Imperial German Navy as the minelayer S.M.S. M–10. In 1918, at the surrender of the German Grand Fleet, at the end of the First World War, she was renamed as the Aktion and in 1919 she passed into private ownership.
She was transferred to Canadian Registry (ON 155164). In 1930 she arrived in Prince Rupert BC and was converted to a passenger vessel to supplement passenger service between Prince Rupert BC and the Queen Charlotte Islands. In 1930–1939 she was owned by Captain Paul Armour, Prince Rupert BC. She was broken up in Prince Rupert BC. (So far I have been unable to find out any details of the operations of this vessel.)
