Gilbert led the massacre of the Jews at Canterbury (April 1264), as Simon de Montfort, 6th Earl of Leicester, had done at London, following which his castles at Kingston and Tonbridge were confiscated by King Henry III. Gilbert and Montfort were both denounced as traitors, but Montfort Knighted Gilbert. The next day Gilbert commanded the second line at the Battle of Lewes (14th May 1264), where fell about 10,000 men. Gilbert took King Henry III prisoner, having hamstrung his horse. As Prince Edward (the future King Edward I) had also been taken, Gilbert and Montfort were now supreme. Later young Edward escaped, and Gilbert and Montfort were proclaimed to be rebels.

In 1265 some of the barons broke their allegiance with Montfort. Edward and Gilbert now joined forces and entered on an active campaign against Montfort, and Gilbert destroyed ships at Bristol and the bridge over the Severn to prevent Montfort's escape. Gilbert shared Edward's victory at Kenilworth (16th July 1265), and at the ensuing Battle of Evesham (4th August, in which Montfort was slain), Gilbert commanded the 2nd division and contributed largely to the victory.

It is recorded that on 11th April 1268 Gilbert commenced work on the building of a new castle at Caerphilly. There were initial setbacks, as the Welsh forces saw it as a threat to them, and there began a lengthy dispute. Prince Llywelyn lost patience with the delays and attacked and burnt the rising fortifications in October 1270. A furious Gilbert took immediate reprisal action, and on 1st June 1271 began again the construction of the castle. King Edward I stepped into the dispute and sent in two bishops to arbitrate and take control of the castle on behalf of the crown. In February 1272 the Constable of Cardiff Castle accompanied by two knights obtained permission to enter the castle to make an inventory of arms and stores. Once inside, the knights left open the castle gates. Forty of Gilbert's men-at-arms entered the castle and evicted the bishops. When summoned to explain, Gilbert denied all knowledge of the plot, and cloaked the events in such a way that the king was forced to accept. The castle was completed during Gilbert's lifetime.

Gilbert was present at Berwick when Robert de Brus surrendered his rights to the Scottish crown (7th November 1292). He died at Monmouth Castle (7th December 1295), and Joan afterwards married 2. (1297, clandestinely) [MONH501] Ralph (see MONTHERMER BARONY). She died April 1307, age 35.

[HERT502] Margaret (born c.1292, 2nd daughter of Gilbert & Joan) married 1. Piers de Gaveston, 1st Earl of Cornwall (executed 1312); then 2. [GLO2501] Earl Hugh (see GLOUCESTER (AUDLEY) EARLDOM).
