She was imprisoned for eight years by the English. From October 1306 to July 1308 she was held at Burstwick-in-Holderness, Yorkshire, where she, only served by two elder women, wrote a letter complaining about her condition (she had only 3 clothes and no headgear or linen bed clothing), before being transferred to Bisham Manor, Berkshire until March 1312. From there, she was moved to Windsor Castle with six attendants and an allowance, where she was held until October 1312, Shaftesbury Abbey, Dorset until March 1313, Barking Abbey, Essex until March 1314, and Rochester Castle, Kent until June 1314. After the Battle of Bannockburn, she was moved to York while prisoner exchange talks took place. At York, she had an audience with King Edward II of England. She was released as part of the ransom for the Earl of Hereford who had been captured after the Battle of Bannockburn on 29 September 1314.
