In Geoffrey, Arthur passes his crown to his relative Constantine after being mortally wounded by the traitor Mordred in the Battle of Camlann. Geoffrey identifies Gildas' "royal youths" as Mordred's two sons, who, along with their Saxon allies, continue their father's insurrection after his death. After "many battles" Constantine routs the rebels, and Mordred's sons flee to London and Winchester, where they hide in a church and a friary, respectively. Constantine hunts them down and executes them before the altars of their sanctuaries. Divine retribution for this transgression comes three years later when Constantine is killed by his nephew Aurelius Conanus (Gildas' Aurelius Caninus), precipitating a civil war. He is buried at Stonehenge alongside other kings of Britain.
