Following his accession in 1154, Henry II sought to reassert English control over Welsh territories and the Welsh Marches. Owain Gwynedd adopted a defensive position, prompting Henry to seek a flanking manoeuvre through the woods of Hawarden to break the Welsh resistance.
Henry II led a detachment through the Hawarden woodland to outflank Owain's forces, but was ambushed by a Welsh contingent commanded by Owain's sons Dafydd and Cynan. English forces suffered significant casualties, the royal standard was dropped, and Henry himself narrowly escaped. Both English and Welsh sources record it as a serious setback for the king.
Although Owain Gwynedd ultimately withdrew and concluded a peace settlement with Henry, contemporary chroniclers widely regarded the engagement as a tactical failure for the English crown. The battle underscored the resilience of Welsh resistance and the difficulty of projecting Anglo-Norman military power into the Welsh interior.
