The queen, Isabella, daughter of the duke of Bavaria, who had been hitherto an inveterate enemy to the Burgundian faction, had received a great injury from the other party, which the implacable spirit of that princess was never able to forgive.

The public necessities obliged the count of Armagnac, created constable of France in the place of D'Albret, to seize the great treasures which Isabella had amassed: and when she expressed her displeasure at this injury, he inspired into the weak mind of the king some jealousies concerning her conduct, and pushed him to seize, and put to the torture, and afterwards throw into the Seine, Boisbourdon, her favorite, whom he accused of a commerce of gallantry with that princess.
The queen herself was sent to Tours, and confined under a guard;[**] and after suffering these multiplied insults, she no longer scrupled to enter into a correspondence with the duke of Burgundy.

As her son, the dauphin Charles, a youth of sixteen, was entirely governed by the faction of Armagnac, she extended her animosity to him, and sought his destruction with the most unrelenting hatred.

She had soon an opportunity of rendering her unnatural purpose effectual.

The duke of Burgundy, in concert with her, entered France at the head of a great army: he made himself master of Amiens, Abbeville, Dourlens, Montreuil, and other towns in Picardy; Senlis, Rheims, Chalons, Troye, and Auxerre, declared themselves of his party.[***] He got possession of Beaumont, Pontoise, Vernon, Meulant, Montlheri, towns in the neighborhood of Paris; and carrying further his progress towards the west, he seized Etampes, Chartres, and other fortresses; and was at last able to deliver the queen, who fled to Troye, and openly declared against those ministers who, she said, detained her husband in captivity.[****] * Le Laboureur, liv.xxxv.chap.
