In 1376 John Savile of Shelley and Golcar (age 51) was elected MP Yorkshire in the Good Parliament. During the Good Parliament, he was sufficiently trusted to conduct Thomas Caterton from Queenborough Castle [Map] for interrogation before Parliament. Caterton had been appealed for treason by Sir John Annesley, and the court party, including Gaunt (age 35), was anxious to protect him from attack. In the event, they were able to hold off the opposition, despite some damning revelations about their conduct of the war-effort. The duke (age 35) himself was singled out for particular criticism, and during the Peasants' Revolt of 1381 he fled into Scotland, leaving his Savoy Palace [Map] to be destroyed by the London mob. Gaunt (age 35) was, understandably, reluctant to cross the border again without the protection of a sizeable bodyguard. In late Jun 1376, therefore, his leading retainers in the north were instructed to provide an escort for his journey to Knaresborough [Map]. Not only did John Savile of Shelley and Golcar (age 51) mobilize a personal retinue of ten men-at-arms and 40 archers; he also helped to suppress the rebellion in the north by serving on two commissions for the punishment of insurgents.

After 28 Apr 1376 William Latimer 4th Baron Latimer of Corby (age 46) impeached (the earliest impeachment in England) during the Good Parliament.
