In 1336 the English returned again, this time under Edward III. The English king had the castle repaired, and again made it his headquarters in Scotland. The following year, however, Sir Andrew Murray, nephew of Sir William and the rightful owner of Bothwell, recaptured the stronghold, again using siege engines. Following his victory he slighted the castle once more, pulling down the west side of the donjon and tumbling it into the Clyde, in order that it could not be reoccupied by the enemy. The castle remained derelict until the 1360s.
