A terrible vengeance was taken on his supporters in the recent schemes.

In the Parliament of 1388 Gloucester, with the four Earls of Derby, Arundel, Warwick, and Nottingham, appealed on a charge of high treason Suffolk and De Vere, the Archbishop of York, the Chief Justice Tresilian, and Sir Nicholas Bramber.

The first two fled, Suffolk to France, De Vere after a skirmish at Radcot Bridge to Ireland; but the Archbishop was deprived of his see, Bramber beheaded, and Tresilian hanged.

The five judges were banished, and Sir Simon Burley with three other members of the royal household sent to the block.
[Sidenote: Richard's Rule] At the prayer of the "Wonderful Parliament," as some called this assembly, or as others with more justice "The Merciless Parliament," it was provided that all officers of state should henceforth be named in Parliament or by the Continual Council.

Gloucester remained at the head of the latter body, but his power lasted hardly a year.
