The Welsh annals record a battle called Gwaith Mawr in 722 in which the Welsh of Powys repelled a Mercian attack. This is one of the few eighth-century battles recorded in Welsh sources before Offa began building his dyke.

Location estimated near the Dee valley where Powys and Mercia repeatedly clashed.
