Minority, 1262. 1533 Being under age at his father's death, he was made a ward of Humphrey de Bohun, 2nd Earl of Hereford.

Battle of Lewes, 1262, Lewes, England. 1533 The Earl commanded the central division of the Baronial army at the Battle of Lewes, which formed up on the Downs west of Lewes. When Prince Edward had left the field in pursuit of Montfort's routed left wing, the King and Earl of Cornwall were thrown back to the town. Henry took refuge in the Priory of St Pancras, and Gilbert accepted the surrender of the Earl of Cornwall, who had hidden in a windmill. Montfort and the Earl were now supreme and de Montfort in effect de facto King of England.

Excommunication, 1264. 1533 On 20 October 1264, Gilbert and his associates were excommunicated by Pope Clement IV , and his lands placed under an interdict .

Having changed sides, de Clare shared the Prince's victory at Kenilworth on 16 July, and in the Battle of Evesham , 4 August, in which de Montfort was slain, he commanded the second division and contributed largely to the victory. On 24 June 1268 he took the Cross at Northampton in repentance and contrition for his past misdeeds.[
