One of five nobles who “appealed” (accused) certain of the leading friends of Richard II of England of treason in November 1387. Thomas of Woodstock, Duke of Gloucester, Richard Fitzalan, Earl of Arundel, Thomas de Beauchamp, Earl of Warwick, Henry of Bolingbroke (Henry IV), Earl of Derby, and Thomas Mowbray, 3rd Earl of Nottingham were opposed to the king’s policy of peace with France. His position had been weakening for some months, and he was forced to summon a parliament to be held in February 1388; at this, the “Merciless Parliament”, the Archbishop of York and others of his friends and their associates were accused of treason or were impeached. Four men, including a former Chief Justice, were executed. Richard II bided his time, gradually restoring his authority until in 1397 he was able to arrest the surviving Lords Appellant and have them accused of treason.
