Cause

Henry II of England launched a summer 1165 military campaign to suppress an alliance of Welsh princedoms led by Owain Gwynedd. The campaign aimed to reassert Anglo-Norman authority over Wales and break the resistance of the allied Welsh rulers.

Event

Welsh chronicles record that a detachment of Welsh troops engaged the Anglo-Norman army in the Ceiriog Valley, inflicting casualties. Whether this constituted a pitched battle, several smaller engagements, or merely a minor skirmish remains disputed, and some historians question whether any fighting occurred at all.

Consequence

Henry II subsequently abandoned the entire 1165 campaign after severe weather thwarted his attempt to cross the Berwyn Mountains. The episode, real or embellished, became embedded in Welsh tradition, though later accounts depend heavily on David Powel's unreliable 1584 chronicle.
