Synod of Chester led to a battle with a victory for who?
Synod of Chester The Synod of Chester (Medieval Latin: "Sinodus Urbis Legion(um)") was an ecclesiastical council of bishops held in Chester in the late 6th or early 7th century. The period is known from only a few surviving sources, so dates and accounts vary, but it seems to have been a major event in the history of Wales and England, where the native British bishops rejected overtures of peace from Augustine's English mission. This led directly to the Battle of Chester, where Æthelfrith of Northumbria seems to have killed the kings of Powys and (possibly) Gwynedd during an attack on the ecclesiastical community at Bangor-on-Dee.
Battle of the Sabis The Battle of the Sabis, also (arguably erroneously) known as the Battle of the Sambre or the Battle against the Nervians (or "Nervii"), was fought in 57 BC near modern Saulzoir in Northern France, between the legions of the Roman Republic and an association of Belgic tribes, principally the "Nervii". Julius Caesar, commanding the Roman forces, was surprised and nearly defeated. According to Caesar's report, a combination of determined defence, skilled generalship, and the timely arrival of reinforcements allowed the Romans to turn a strategic defeat into a tactical victory.
