On 3 March, Harclay was arraigned before a royal justice in Carlisle, but was denied a proper hearing. He was brought forward apparelled in his robes of estate as a knight and earl. His spurs of knighthood were hewed off, and his sword was broken over his head. He was stripped of his robes, and proclaimed to be no knight, but a knave. He was then convicted as a traitor, and condemned to be hanged, drawn and quartered. He behaved with dignity at his execution, where he maintained that he had acted as he did out of concern for the best interest of the country. After his death, his head was taken to the king at Knaresborough in Yorkshire, before it was hung up on London Bridge. The four parts of his body were dispersed around the country, and displayed in Carlisle, Newcastle, Bristol, and Dover.
