the timeline. Even so, Cador undermines the success of Arthur as he won against the Saxons in a far off region. Historians from both Saxony and Britain do not note on any battle occurring in that region until the sixth century. The legitimacy of this battle could be completely fabricated for literary purposes. Anglo-Saxon Chronicle Scholars have speculated that the legitimacy of Cador's battles can be found through the Anglo-Saxon Chronicle, presumably written by Alfred the Great. Since there is only one named British Commander, Vortigern, scholars have aligned the timelines in the Anglo-Saxon Chronicle and the Historia Regum Britanniae to assess the legitimacy of Cador. Many similarities between the battles can be noted. There is an encounter in York, or along the Canterbury-London road with anywhere between 3,000 and 4,000 British soldiers. Here, Arthur and the British retreat to London in both versions of history. The next battle with the supposed Cador is in Thanet, which is noted in both Anglo-Saxon Chronicle and Historia Regum Britanniae. The British Commander in the Anglo-Saxon Chronicle, despite being unnamed, is speculated to be the Cador in Historia Regum Britanniae because of the similarities. Historical ruler Cado was the historical son of a Dumnonian king named Gerrens whom he succeeded as monarch. Traditionally he was a good friend of Arthur; they even ruled together in the Vita Sanctus Carantoci (Life of St. Carantoc). He also seemed to share a good relationship with King Caradoc of Gwent. Possibly he gave his name to four hillforts, all named Cadbury which may be "Cado's fort", one each near to Clevedon, Congresbury and Sparkford in Somerset and one by the Exe in Devon north of Crediton. Cadson Bury hill fort lies just outside Callington, also known as Celliwig in Cornwall. Legend In Geoffrey's History and elsewhere, Arthur's future queen Guinevere was raised as Cador's ward. Cador is also said to be of Roman stock. His son Constantine was given the kingship of Britain by Arthur as the latter lay ailing on the field of Camlann. To the Brut Tysilio the translator adds the information that Cador was son of Gorlois, presumably by Igraine, which would make him Arthur's maternal half-brother. This same text also gives Cador a son, Mayric, who dies fighting the Romans. The same account appears in Richard Hardyng's Chronicle where Cador is called Arthur's brother "of his mother's syde." In Layamon's Brut Cador appears
