This Day in History: 1264-05-14
On 14th May 1264, John de Warenne, the 6th Earl of Surrey and owner of Sandal Castle, was present at the Battle of Lewes in support of King Henry III against the forces of Simon de Montfort, 6th Earl of Leicester. King Henry was captured along with his son, Prince Edward, his brother, Richard, Earl of Cornwall, and various lords and Scots barons. With Henry’s capture at the battle, John would flee to the continent for at least a year, with his estates being confiscated, although they would be subsequently returned. John had been a strong supporter of Henry in the first Barons’ War but had switched to Simon de Montfort, only to return to the king. He had opposed the initial baronial reform plan in 1258 but did capitulate to take the oath of the Provisions of Oxford.
