The Battle

History & Significance

Caernarfon Castle was the symbolic crown of English power in north Wales and Glyndwr attempted it multiple times. The 1404 assault came at the peak of Welsh power when Glyndwr had just captured Harlech and Aberystwyth. Despite controlling almost all of Wales, he could not reduce Caernarfon. The garrison of only twenty-eight men famously held the castle. Caernarfon never fell to Glyndwr and remained a constant symbol of English resistance.

Forces Involved

Welsh rebels (Glyndŵr): c. 1,500–3,000 men in siege. English garrison: c. 150–250 men.
