In the middle of this confrontation, Henry unexpectedly fell ill and died near Lyons-la-Forêt. It is uncertain what, if anything, Henry said about the succession before his death. Contemporary chronicler accounts were coloured by subsequent events. Sources favourable to Matilda suggested that Henry had reaffirmed his intent to grant all his lands to his daughter, while hostile chroniclers argued that Henry had renounced his former plans and had apologised for having forced the barons to swear an oath of allegiance to her.
