 On 20 June , the King 's uncle , Thomas of Woodstock , and Robert Tresilian , the replacement Chief Justice , were given special commissions across the whole of England . Thomas oversaw court cases in Essex , backed up by a substantial military force as resistance was continuing and the county was still in a state of unrest . Richard himself visited Essex , where he met with a rebel delegation seeking confirmation of the grants the King had given at Mile End . Richard rejected them , allegedly telling them that " rustics you were and rustics you are still . You will remain in bondage , not as before , but incomparably harsher " . Tresilian soon joined Thomas , and carried out 31 executions in Chelmsford , then travelled to St Albans in July for further court trials , which appear to have utilised dubious techniques to ensure convictions . Thomas went on to Gloucester with 200 soldiers to suppress the unrest there . Henry Percy , the Earl of Northumberland , was tasked to restore order to Yorkshire .
