Saye and Sele was a supporter of William de la Pole, 1st Duke of Suffolk, the principal power behind the throne of Henry VI.
After Suffolk's deposition and murder in 1450, Fiennes was imprisoned in the Tower with his son-in-law William Cromer, deputy-sheriff of Kent in 1444.
[2] Having been released from the tower and handed over to the rebels as a placatory gesture by the King, Baron Saye was brought to Guildhall for a sham trial.
The heads of the two men were put on pikes and unceremoniously paraded through the streets of London while their bearers pushed them together so that they appeared to kiss.
Shortly after the burial, English settlers dispossessed from their property in Bayeux and Caen (who had recently arrived in London) removed his coat of arms from the pillar by his grave and reversed it - an act intended to dishonour the dead.
