 Their attempt failed and the three opposing British kings were killed (they are named as Commagil of Gloucester, Condidan of Cirencester, and Farinmagil of Bath).Their routed forces were driven north of the River Severn and south of Bath where it appears they began the construction of the defensive earthwork called the "Wansdyke" in a doomed attempt to prevent more territory from being lost.The military historian Lieutenant-Colonel Alfred Burne, employing his theory of 'Inherent Military Probability' opted for a simpler explanation for the battle than Baddeley.
