Shot in mid-1939 as S.S. Ionian (also shown as Her Last Trip), Humphrey Jennings’s GPO short follows the Royal Mail steamer on a last peacetime run through the Mediterranean—Gibraltar, Malta, Alexandria, Haifa—under the gaze of the Mediterranean Fleet (HMS Barham, Malaya, Warspite). After the Ionian was sunk by a German mine on 29 November 1939 en route from Crete to Hull, the film was recut and released as Cargoes.
