Synod of Chester led to a battle with a victory for who?
Battle of Chester The Battle of Chester (Old Welsh: "Guaith Caer Legion"; Welsh: "Brwydr Caer") was a major victory for the Anglo Saxons over the native Britons near the city of Chester, England in the early 7th century. Æthelfrith of Northumbria annihilated a combined force from the Welsh kingdoms of Powys, Rhôs (a cantref of the Kingdom of Gwynedd) and possibly Mercia. It resulted in the deaths of Welsh leaders Selyf Sarffgadau of Powys and Cadwal Crysban of Rhôs. Circumstantial evidence suggests that King Iago of Gwynedd may have also been killed.
Battle of Hingston Down The Battle of Hingston Down took place in 838 at Hingston Down in Cornwall between a combined force of Cornish and Vikings on the one side, and West Saxons led by Egbert, King of Wessex on the other. It resulted in a West Saxon victory.
