Tommy, Alex and Gibson join some soldiers of a Highlanders regiment and hide inside a beached trawler in the intertidal zone outside the Allied perimeter, waiting for the rising tide to refloat it. German troops shoot at the boat, and water enters through the bullet holes. Alex, hoping to lighten the boat, accuses Gibson, who has stayed silent, of being a German spy. Gibson reveals he is French; he stole the identity of the dead British soldier he buried, hoping to be evacuated with the British. The group abandons the boat when it begins to sink, but Gibson is entangled in a chain and drowns. When a nearby minesweeper is sunk by a bomber, "Moonstone" manoeuvres to take on those in the water, including Tommy and Alex. Peter discovers that George is dead. Asked by the shell-shocked soldier, he lies and says that George is fine. Farrier reaches Dunkirk, before his fuel runs out. Gliding over the beach, he shoots down a dive-bomber, saving ships and troops, and then lands beyond the perimeter. He sets fire to his plane before being taken prisoner by the Germans. In all, 300,000 men are evacuated. Royal Navy Commander Bolton stays to oversee the evacuation of the French. Arriving back in Weymouth, Dawson is congratulated for having saved so many men. The shell-shocked soldier sees George's body being carried away. Peter goes to the local newspaper; a front-page article commends George as a hero. Tommy and Alex board a train, and receive a hero's welcome when the train arrives in Woking.
