Bismarck: 24 Hours To Doom Channel 4, 6.55pm

Based on Iain Ballantyne’s book, this documentary casts fresh light on one of the Second World War’s most remarkable sea battles. Charting Britain’s response after the pride of the Royal Navy, HMS Hood, was destroyed by the Bismarck in 1941, the film counts down the German battleship’s final 24 hours as British air and naval forces closed in. ★★★★
