 Andrew Harclay was richly rewarded for his loyal and competent performance at Boroughbridge . On 15 March he was created Earl of Carlisle , and promised lands worth 1000 marks yearly . Yet Harclay , who had turned down Lancaster 's overtures to join in the rebellion , was no great adherent of the King . As a warden of the Scottish Marches he grew constantly more frustrated with the King 's idleness , and eventually negotiated a peace treaty with the Scots . This action on Harclay 's part amounted to treason , and early in 1323 he was apprehended by the King 's men , and hanged , drawn and quartered .
