Morning Departure

Morning Departure (released as Operation Disaster in the United States) is a 1950 British naval drama film about life aboard a sunken submarine, directed by Roy Ward Baker, and starring John Mills and Richard Attenborough. It is based on a stage play of the same name by Kenneth Woollard, which had also been shown as a live TV play by the BBC both in 1946 and 1948. It was the feature film debut of Michael Caine. Plot The British submarine HMS Trojan is out on a routine exercise to test its new snorkel mast. She encounters an unrecovered Second World War magnetic mine. When she dives, the mine is set off and blows off the bow of the submarine. The after section floods from the displaced snorkel mast, killing the 53 crewmen in the bow and stern sections. She settles to the bottom leaving twelve crew members alive amidships, saved by the watertight doors which were closed by order of the captain when he realised the imminent danger. When the shore base becomes aware that Trojan is overdue, surface rescue vessels are sent out to investigate. The captain of the submarine, Lieutenant Commander Peter Armstrong, expels a quantity of oil, which rises to the surface and shows their position. Following standard escape procedure, a diver is sent down with an air line, while everyone prepares for the rescue. Armstrong selects the first four for release; they escape through the gun hatch and are picked up on the surface. The eight remaining crew assume there are plenty of breathing sets for them all to escape. However, the captain discovers that all but four have been destroyed in the blast. This means four will be trapped until a full salvage operation can be carried out, which may take a week or more. Armstrong deals from a pack of cards to decide who goes and who remains. The cook, A/B Higgins, and the first lieutenant, Lieutenant Manson, get low cards. Three get high cards, there is a tie between Stoker Snipe and E.R.A. Marks. On losing a re-deal, young Snipe goes berserk with fear and has to be physically restrained. Armstrong volunteers to stay. Marks agrees.
