{ 1342.} This event seemed to put an end to the pretensions of the count of Mountfort; but his affairs were immediately retrieved by an unexpected incident, which inspired new life and vigor into his party. Jane of Flanders, countess of Mountfort, the most extraordinary woman of the age, was roused, by the captivity of her husband, from those domestic cares to which she had hitherto limited her genius; and she courageously undertook to support the falling fortunes of her family No sooner did she receive the fatal intelligence, than she assembled the inhabitants of Rennes, where she then resided; and carrying her infant son in her arms, deplored to them the calamity of their sovereign. She recommended to their care the illustrious orphan, the sole male remaining of their ancient princes, who had governed them with such indulgence and lenity, and to whom they had ever professed the most zealous attachment. She declared herself willing to run all hazards with them in so just a cause; discovered the resources which still remained in the alliance of England; and entreated them to make one effort against a usurper, who, being imposed on them by the arms of France, would in return make a sacrifice to his protector of the ancient liberties of Brittany. The audience, moved by the affecting appearance, and inspirited by the noble conduct of the princess, vowed to live and die with her in defending the rights of her family: all the other fortresses of Brittany embraced the same resolution: the countess went from place to place encouraging the garrisons, providing them with every thing necessary for subsistence, and concerting the proper plans of defence; and after she had put the whole province in a good posture, she shut herself up in Hennebonne, where she waited with impatience the arrival of those succors which Edward had promised her. Meanwhile she sent over her son to England, that she might both put him in a place of safety, and engage the king more strongly, by such a pledge, to embrace with zeal the interests of her family.
Charles of Blois, anxious to make himself master of so important a fortress as Hennebonne, and still more to take the countess prisoner, from whose vigor and capacity all the difficulties to his succession in Brittany now proceeded, sat down before the place with a great army, composed of French, Spaniards, Genoese, and some Bretons; and he conducted the attack with indefatigable industry.[*]
