With great pomp, this illustrious scion of the house of the Earls of Macduff led Bruce to the regal chair. The English chronicler crustily remarks: "She was mad for the beauty of the fool who was crowned." The English king was enraged at the presumption of his vassal, and sent out his soldiers against the Scottish sovereign. In the notable battle which followed, the forces of Bruce were routed and he himself made a fugitive. Other reverses befell the arms of the Scotch, and among those who were carried away captive to gratify the lust for vengeance of the English was the noble lady who had proudly inducted Bruce into the royal power. Isobel of Buchan was carried to Berwick, and condemned to a fate which can best be described in the words of an early chronicler: "Because she has not struck with the sword, she shall not die by the sword, but on account of the unlawful coronation which she performed, let her be closely confined in an abode of stone and iron, made in the shape of a cross, and let her be hung up out of doors in the open air of Berwick, that both in her life and after her death she may be a spectacle and an eternal reproach to travellers." For four years she suffered the imposition of this heinous punishment, which was then mitigated to imprisonment in the monastery of Mount Carmel at Berwick. After three years she was removed to the custody of Henry de Beaumont. Her final fate is unknown, but it is presumable that, if she lived, her release from durance was secured by the victory of Bannockburn.
