The Gauntlet is a children's historical novel, written by Ronald Welch, and published in 1951.
The story begins with Peter Staunton and his friend Gwyn Evans finding a rusted iron gauntlet while on holiday in the Brecon Beacons.
Peter then spends time learning about medieval life in Wales and neighbouring England and, after falling asleep in the garden of Carreg Cennen Castle, finds himself back in medieval times.
He has a number of experiences, such as attending a medieval banquet, visiting the abbey, watching a joust, before returning to fight in a siege of the castle by the Welsh, where he is hit and falls unconscious.
He wakes back in his own time, and tries to convince his friends there that he was not simply dreaming.
