D'Amory switched sides, joining the Marcher Lords led by Roger Mortimer and Thomas, Earl of Lancaster in the rebellion known as the Despenser War.

He died of his wounds at Tutbury Castle, Staffordshire after 16 March 1322, having been captured by the royalist forces at the Battle of Boroughbridge where the rebels were soundly defeated.

With the support of the king he began to take over the adjacent lordships in south Wales, with the aim to consolidate a huge landholding by fair means or foul.

When Richard handed over his rights as patron to Elizabeth in 1346, she made further grants, including providing the college with statutes in 1359,[6] and it became known as Clare Hall.
