Battle of Cirencester

The Battle of Cirencester was fought in 628 at Cirencester in modern-day England. The conflict involved the armies of Mercia, under King Penda, and the West Saxons, under Kings Cynegils and Cwichelm. The Mercians defeated the Saxon army and, according to Bede, "after reaching an agreement", took control of the Severn valley and the minor kingdom of the Hwicce, which had been under the influence of Wessex since the Battle of Dyrham in 577.
