Regardless of Edward's intentions when founding the abbey, the deteriorating political situation and eventual civil war between his father and the nobility —in which Edward played a prominent role— stalled plans for the abbey's build. In 1265 the rebel barons were defeated at the Battle of Evesham, and the following year negotiations were completed for the establishment of a Cistercian monastery in Darnhall in Cheshire. This was to be paid for with the manor house and estate of the earls of Chester, which were now in royal hands. In August 1270, Edward granted another charter at Winchester to his new abbey with a further endowment of land and churches.
