Merlin Season 1 Episode 10 - The Moment of Truth

Hearing that his village is being threatened by a warlord and his gang, Merlin travels home with Gwen, Morgana and Arthur, the latter doing his best to drill the peaceful villagers into a fighting force. Merlin's friend William is dismissive of Arthur's efforts, feeling they constitute egoism, though he ultimately saves the young prince's life. Nonetheless the villagers are inexperienced in martial ways and Merlin must use magic and conjure up a wind-storm to help see off the bandits.
