 Percy was left in charge of Dunstanburgh as part of Edward IV's attempts at reconciliation, but the next year he once again switched sides, returning the castle to the Lancastrians.Percy died at the Battle of Hedgeley Moor in 1464, and the Earl of Warwick reoccupied the castle that June following a short siege.The castle was probably damaged during the wars, but, other than minor repairs in 1470, nothing was spent on repairs and it fell into disrepair.
