It happened that while King Arthur was away from England, Sir Mordred decided to rule instead of him. So he sent letters, which looked like they had come from across the sea, saying that King Arthur had been killed in battle with one of his knights.
When King Arthur returned to his kingdom, he determited to set a day when he might be revenged on Sir Mordred for his evil deeds.
Never was there seen a more sorrowful battle in all the land. King Arthur and Sir Mordred stood between thier armies. They fought fiercely until the close of the day, when many noble knights lay dead on the field.
