Ionia was built in 1913 in Hartlepool as the Digby for Furness Lines UK-Canada service. During WW1 she served with the Royal Navy as HMS Digby, and later with the French Navy as Artois. After the war she returned to her old route, again as Digby, and from 1925 operated on the New York-West Indies service as the Dominica. She was then sold in 1934 to become the flagship of the United Baltic Corporation as the Baltrover. Route was London-Gdynia. During WW2 she reverted to her original transatlantic route. In 1946 she was sold to Hellenic Mediterranean Lines for £950,000, appearing in service in 1948 as the Ionia. Her route was Marseille-Genoa-Naples-Piraeus-Alexandria-Limassol-Port Said. Sold in 1964, she was lost as Ionian the following year (shipwrecked).
