On 02 Dec 1307 King Edward II of England (age 23) held a tournament to celebrate Piers Gaveston's (age 23) recent wedding. Gaveston took the opportunity to humiliate the older nobility including [his brother-in-law] John Warenne 7th Earl of Surrey (age 21), Humphrey Bohun 4th Earl Hereford 3rd Earl Essex (age 31) and Edmund Fitzalan 9th Earl of Arundel (age 22) further increasing his unpopularity.

On 09 Jun 1312 Piers Gaveston 1st Earl Cornwall (age 28), under the protection of Aymer de Valence 2nd Earl Pembroke (age 37), stayed at The Rectory, Deddington whilst en route south. Aymer de Valence 2nd Earl Pembroke left Piers Gaveston 1st Earl Cornwall there whilst he left to visit his wife. The following morning Guy Beauchamp 10th Earl Warwick (age 40), with Edmund Fitzalan 9th Earl of Arundel (age 27), Humphrey Bohun 4th Earl Hereford 3rd Earl Essex (age 36) and John Botetort 1st Baron Botetort (age 47) arrested Piers Gaveston 1st Earl Cornwall and took him to Warwick Castle [Map].

Around 15 Jun 1312 Piers Gaveston 1st Earl Cornwall (age 28) was tried at Warwick Castle [Map] by Guy Beauchamp 10th Earl Warwick (age 40), Humphrey Bohun 4th Earl Hereford 3rd Earl Essex (age 36), Thomas Plantagenet 2nd Earl of Leicester, 2nd Earl Lancaster, Earl of Salisbury and Lincoln (age 34) and Edmund Fitzalan 9th Earl of Arundel (age 27). He was condemned to death.

Froissart Book 1 Chapter 12. When the queen (age 31) and her barons and all her company were lodged at their ease, then they besieged the castle [Map] as near as they might. The queen caused sir Hugh Spencer (age 65) the elder and the earl of Arundel (age 41) to be brought forth before Edward her son (age 13) and all the barons that were there present, and said how that she and her son should take right and law on them according to their deserts. Then sir Hugh Spencer said, 'Madam, God be to you a good judge and give you good judgment¹, and if we cannot have it in this world, I pray God we may have it in another.' Then stept forth Sir Thomas Wake (age 29), a good knight and marshal of the host, and there openly he recounted their deeds in writing, and then turned him to another ancient knight to the intent that he should bring him on that case fauty¹, and to declare what should be done with such persons, and what judgment they should have for such causes. Then the said knight counselled with other barons and knights, and so reported their opinions, the which was, how they had well deserved death for divers horrible deeds, the which they have commised, for all the trespass rehearsed before to justify to be of truth;³ wherefore they have deserved for the diversities of their trespasses to have judgment in three divers manners-first, to be drawn, and after to be headed, and then to be hanged on the gibbet. This in likewise as they were judged so it was done and executed before the castle of Bristow [Map] in the sight of the king and of sir Hugh Spencer the younger (age 40). This judgment was done in the year of our Lord MCCCXXVI., on Saint Denis' day in October [Note. Saint Denis' day is 09 Oct not 27 Oct?].

Note 1. This should be, 'God give us a good judge and good judgment '; but Verard's edition, from which the translation was made, has 'vous' for 'nous.'

Note 2. This appears to mean, ' To the intent that he should find him guilty on the charge' ('fauty' for 'faulty'); but the original means, 'To the intent that he should declare upon his fealty (féaulté) what should be done with such persons,' etc.

Note 3. Or rather as follows: 'That the accused had well deserved death for divers horrible deeds which they had heard in that place rehearsed, and held them for true and manifest.'

Adam Murimuth Continuation. [17 Nov 1326]. Lord Hugh Despenser the Younger (age 40), Robert de Baldock, and Simon of Reading were brought to the Queen, who was at Hereford. However, before their arrival, the Earl of Arundel (age 41), John Daniel, and Thomas de Micheldever were beheaded in Hereford through the agency of Lord Roger Mortimer (age 39), who harbored a deep hatred for them and whose advice the Queen followed in all matters.

Dominum vero Hugonem Dispenser filium, Robertum de Baldok, et Simonem de Redynges ad reginam, que fuit Herefordiæ, conduxerunt. Sed ante eorum adventum fuerunt decollati Herefordiæ comes de Arundel, Johannes Daniel, et Thomas de Michedeure, per procurationem domini Rogeri de Mortuo mari, qui perfecto odio oderat illos et cujus consilium regina per omnia sequebatur.

And þe same day, a litil fro þens, was Sir Iohn [Edmund] of Arundel (age 41) biheuede; for he was on of Sir Hugh þe Spensers conseilers.

Lanercost Chronicle. [17 Nov 1326]. After a short interval the Earl of Arundel (age 41) was captured likewise. He had married the daughter of Sir Hugh the younger¹, and had been, with Hugh, one of the king's counsellors. He was condemned to death in secret, as it were, and afterwards beheaded. Meanwhile all who were captives and prisoners in England on account of their adherence to the oft-mentioned Earl of Lancaster were released, and the exiles were recalled, and their lands and heritages, whereof they had been disinherited, were restored to them in full ; wherefore they joined the party of the queen and her son eagerly and gladly.

Note. This is a mistake. Edmund Fitzalan 9th Earl of Arundel married [his wife] Alice Warenne Countess Arundel daughter of William Warenne. It was Edmund' son [his son] Richard (age 20) who had married [his daughter-in-law] Isabel (age 14), daughter of Hugh "Younger" Despencer 1st Baron Despencer (age 40).
