Watch The Cockleshell Heroes

World War II action film about the training of ten marines for a sabotage mission. Whipped into shape by a no-nonsense Sergeant Major, the men are charged with destroying a number of giant German battleships in the harbour at Bordeaux, a mission they will carry out by entering the harbour in canoes and attaching limpet mines to the vessels. Facing almost impossible odds, the men demonstrate their resolve, and pursue their task with great courage.
