Did You Know?


The fires on the ship are clearly not burning oil but gas. Otherwise there would be thick black smoke and pouring water on it from buckets would result in an explosive spread (for that same reason one should never try to extinguish burning fat in a frying pan by pouring water on it). See more »

Quite a shock
10 August 2003 | by (United Kingdom) – See all my reviews

The captain of the Jervis Bay, Captain E. S. F. Fegen Royal Navy, was the escort commander for convoy HX84 traveling between Halifax and Great Britain.

The Jervis Bay was an armed merchant cruiser only equipped with four inch guns but quite adequate to deal with any German U boats which might happen to ' chance their arm. '

It was therefore quite a shock when he encountered the German pocket battleship, Admiral Scheer in the middle of the Atlantic Ocean. Certainly not where he would have expected a German surface raider to be.

Taking a gamble Captain Fegen engaged the raider, itself equipped with radar controlled eleven inch guns, and thus allowed the convoy a further twenty minutes to escape into the darkness which by that time was beginning to fall.

Several of the merchant ships were still badly damaged subsequently by the Admiral Scheer. San Demetrio was abandoned by her captain and crew, but later rejoined by part of her crew without the captain. This latter point together with the refusal to accept assistance once in home waters allowed the insurers to make salvage payments to all who embarked on the perilous voyage.

A member of the party interviewed after the war said that the men would have made every effort to save the ship and cargo in any event. Great Britain being upon its knees and fighting alone for her very existence against Germany, Italy and Japan with a neutral USSR and USA observing with a casual interest.

The King later awarded Captain Fegen the Victoria Cross in recognition of the courageous sacrifice of himself and his crew.

The film renders an entertaining account of this annal of the sea.
