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 Ushant (1778) The Battle of Ushant (also called the First Battle of Ushant) took place on 27 July 1778, and was fought between French and British fleets 100 mi west of Ushant, an island at the mouth of the English Channel off the north-westernmost point of France. The battle, the first major naval engagement between the French and British fleets in the American Revolutionary War, ended indecisively and led to political conflicts in both countries.
