Pay close attention to the beginning of
San Demetrio, London. The whole film is based quite accurately on a true story, although there's the addition of an American to attract the American audience. But that's forgiveable.
The San Demetrio was a part of convoy HX-84 crossing the North Atlantic in October 1940. She had picked up a cargo of aviation fuel in Galveston and was bound for Avonmouth. The convoy had minimal protection, just one armed merchant cruiser,
HMS Jervis Bay, an old liner that had been fitted with a few WWI vintage, 6 inch guns.
So when the convoy was attached by the
Admiral Scheer, a German pocket battleship, everybody in the convoy knew that they were in trouble. With her vastly superior speed and her six 11 inch guns and extensive minor armaments she would cause problems even for the best that the Royal Navy had to offer. If the
Admiral Scheer had got in amongst the ships in the convoy she could have caused a lot of damage very quickly.
But
HMS Jervis Bay was there to protect the convoy, even if she was vastly out-gunned. The Royal Navy didn't get its reputation by running away from a fight. So the
Jervis Bay steamed in to the attack with all guns blazing!
She was blown out of the water before she landed a single shot on the
Admiral Scheer of course. But that action lasted for about 20 minutes and gave the ships in the convoy time to scatter so that the
Admiral Scheer couldn't get all of them.
The
Admiral Scheer managed to sink 5 of the smaller ships in the convoy but that's a lot fewer than she would have done without the
Jervis Bay. By now darkness was falling and the
Admiral Scheer could only land a few shells on the upper works of the
San Demetrio that started a few fires and bearing in mind their cargo of aviation fuel, the crew wisely took to the lifeboats.
The rest of the story of what happened to the
San Demetrio and her crew (or part of it) is detailed in the film.
For their sacrificial delaying action, the crew of the
Jervis Bay went down in Naval history and the skipper was awarded a VC
