the Welsh were heartily fed up. In September 1294 they rebelled. During the revolt insurgents tried to put a stop to works at Caernarfon—not so much lying down in front of the bulldozers as setting out to burn the entire building to the ground. The site and half-built town around it was sacked and captured. Newly constructed town walls were pulled down. When the rebellion was crushed, Master James and his on-site deputy, an expert mason called Master Walter of Hereford, were dismayed to find their progress set back by months, if not years.
