In February 1306 Robert Bruce murdered John Comyn, a leading rival, in a church. Bruce went on to take the crown, but Edward's army overran the country yet again after defeating Bruce's small army at the Battle of Methven. Despite the excommunication of Bruce and his followers by Pope Clement V, his support slowly strengthened; and by 1314, with the help of leading nobles such as Sir James Douglas and the Earl of Moray, only the castles at Bothwell and Stirling were still under English control.
