On 31 Oct 1266 the Dictum of Kenilworth was issued. The Dictum was a peace agreement between King Henry III of England (age 59) and the rebels who were besieged in the impregnable Kenilworth Castle [Map]. The committee included:

Bishop Walter Branscombe (age 46).

Archbishop Walter Giffard (age 41).

Bishop Nicholas Ely.

Gilbert de Clare 8th Earl Gloucester 7th Earl Hertford.

Humphrey Bohun 2nd Earl Hereford 1st Earl Essex (age 62).

Philip Basset (age 82).

John Balliol (age 58).

Robert Walerand.

Alan Zouche (age 63).

Roger Somery 2nd Baron Dudley (age 76), and.

Warin Bassingbourne.

Robert Ferrers 6th Earl of Derby (age 27) and Henry Hastings (age 31) were fined seven times their annual income. The Dictum, however, required the rebels to pay their fines before being restored to their lands; something of a Catch-22 since if they weren't restored to their lands, they would have no income to pay the fine.
