When the king's uncle, Odo of Bayeux, raised a rebellion against the king in 1088, St-Calais was implicated in the revolt. William Rufus laid siege to St-Calais in the bishop's stronghold of Durham, and later put him on trial for treason. A contemporary record of this trial, the De Iniusta Vexacione Willelmi Episcopi Primi, is the earliest surviving detailed contemporary report of an English state-trial. Imprisoned briefly, St-Calais was allowed to go into exile after his castle at Durham was surrendered to the king. He went to Normandy, where he became a leading advisor to Robert Curthose, Duke of Normandy, the elder brother of William Rufus. By 1091, St-Calais had returned to England and regained royal favour.
