Battle of Crug Mawr

The Battle of Crug Mawr (Welsh: Brwydr Crug Mawr), sometimes referred to as the Battle of Cardigan, took place in September or October 1136, as part of a struggle between the Welsh and Normans for control of Ceredigion, West Wales. The battle was fought near Penparc, northeast of Cardigan, probably on the hill now known as Banc-y-Warren; it resulted in a rout of the Norman forces, setting back their expansion in West Wales for some years.

The Battle of Crug Mawr was fought in September or October 1136 between the Welsh forces of Rhys ap Gruffydd of Deheubarth and Norman troops led by William de Braose. The Welsh victory weakened Norman control in Ceredigion and marked a significant step in the reassertion of Welsh authority in the region.
