Arthur and Mordred's forces meet in battle. The fog from the dragon's breath shrouds Arthur's cavalry charge against Mordred's battle line, lending Arthur's depleted force the element of surprise against their more numerous foes. Lancelot arrives unexpectedly, tearing through Mordred's troops with savage fury and turning the tide of battle, but later collapses from his unhealed self-inflicted wound. Arthur and Lancelot reconcile, and Lancelot dies. Mordred stabs Arthur with a spear, but Arthur kills Mordred with Excalibur. Arthur tells Perceval to throw Excalibur into a pool of water, reassuring him that a new king will come and the sword will return. Perceval throws Excalibur, and the Lady of the Lake catches it. Perceval returns to see Arthur lying on a ship attended by three ladies clad in white, sailing towards Avalon.
