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 Corbione The Battle of Corbione took place in 446 BC. General Titus Quinctius Capitolinus Barbatus and legatus Spurius Postumius Albus Regillensis led Roman troops to a victory over the Aequi tribes of north-east Latium and the Volsci tribes of southern Latium. The Romans had already defeated the Aequi in the Battle of Mons Algidus, so that the Battle of Corbione definitely marked the dominion of the Romans over this tribe.
