 The cross is mentioned in Ralph of Diceto, who says that as a result of Richard I's campaigns in 1194 "from the castle of Verneuil until one arrives at Charles's Cross no rebels exist" ("a castello Vernolii quousque veniatur ad crucem Karoli nullus ei rebellis existat").The "Annales sancti Albini andegavensis" (or "Annales de Saint- Aubin") record that when John became King of England in 1199 he "acquired all the kingdom which was his father's as far as the cross of King Charles" ("adquisivit totum regnum quod erat patris sui usque ad crucem Caroli regis").Researchers have proposed various interpretations of the evidence for the cross's location for centuries.
