So soon as Richard's cousin, the Earl of Derby, heard of the approach of Gloucester, he quitted the Court with the Earl of Warwick, went to Waltham Cross, and there joined him. The members of the Council of Eleven were there already. On Sunday, the 17th of November, the Duke entered London with an irresistible force and "appealed" of treason the Archbishop of York, De Vere, Duke of Ireland, De la Pole, Earl of Suffolk, Sir Robert Tresilian, Chief Justice of England, and Sir Nicolas Brember, Knight, a London grocer and Lord Mayor of London. The favourites instantly took to flight. De la Pole, the condemned Chancellor, succeeded in reaching France, where he died soon after; De Vere, Duke of Ireland, got to the borders of Wales, where he raised an army, acting in concert with the King; it was resolved he should march to London. The Archbishop of York escaped to Flanders, where he spent the rest of his days as a village priest. The fate of Chief Justice Tresilian must be told in the words of Sir John Froissart. Richard had gone to Bristol to organize an army against the Duke of Gloucester, and De Vere, the Duke of Ireland, was with him there. "While the army was collecting, the King and the Duke in secret conference, determined to send one of their confidential agents to London, to observe what was going forward, and if the King's uncles still remained there, to discover what they were doing. After some consultation, they could think of no proper person to send on this errand; when a knight who was cousin to the Duke, called Sir Robert Tresilian, stepped forth, and said to the Duke, 'I see the difficulty you have to find a trusty person to send to London; I, from love of you, will risk the adventure.' The King and the Duke, well pleased with the offer, thanked him for it. Tresilian left Bristol disguised as a poor tradesman, mounted on a wretched hackney. He continued his road to London, and lodged at an inn where he was unknown; for no man could have ever imagined that one of the King's counsellors and chamberlains would have appeared in so miserable a dress.
