The 1401 capture reveals the human weakness inside an imposing defensive system. Two Welsh rebels connected to Owain Glyndŵr's rising approached while pretending to be carpenters repairing the castle. Once admitted, they killed the watchman and took control from within rather than defeating the walls directly. Reinforcements then captured the rest of the walled town and held out for three months. Their negotiated surrender and royal pardons show that infiltration, bargaining, and local revolt could matter as much as siege engineering.
