Convoy is a 1940 British war film, produced by Ealing Studios, directed by Pen Tennyson and starring Clive Brook, John Clements and Edward Chapman.

[3]A Royal Navy cruiser, HMS Apollo, commanded by Captain Tom Armitage returns to base to find all leave has been cancelled and they are to start out straight away for a special mission.

Supplemented with a new first officer, Lieutenant Cranford who turns out to have caused the captain's divorce a few years earlier, they are sent to meet a convoy in the North Sea and escort it safely into British coastal waters.

Eventually, a North Sea patrol destroyer comes to the rescue, sinking the U-boat and escorts the freighter to the convoy, where the captain and his ex-wife meet and come to an understanding.

Writer and director Pen Tennyson served in the Royal Navy Volunteer Reserve (RNVR) at the time of the production of Convoy.

Deutschland was the lead ship of the heavy cruisers (termed pocket battleships by the British) which also included Admiral Sheer and Graf Spee.

Deutschland was renamed Lutzow in January 1940 after the loss of Graf Spee in the Battle of the River Plate and sunk as a target ship by the Russian navy in 1947.
