Answer:
The basic story:
Town terrorised by evil fire-breathing dragon.
Dragon demands a beautiful maiden to eat every night or he burns the village to the ground.
George the Knight rides into town on his white horse, is very upset when her hears the story and goes off to kill the dragon.
First he tried with his wooden spear which didn't work It just breaks on the dragons armour like scales.
Undeterred he goes back with his sword and fight a gruesome battle until he kills the beast. (He just stabbs it to death - I think he blinds it by getting it in the eye or maybe under the chin or through the mouth - there are many different versions ofthe tale).
Moral of the story : courage, strength and determination.
Of course, this is how the Knight told the story. The dragon tells it a little differently...
