The door of the tower, V, opening into the bailey, had been broken in; but the stairs were so well barricaded with stones and _débris_ that it was impossible to clear it; and even should this be done the assailants would be easily overpowered by the defenders. A wooden bridge connected the curtain of the bailey on this side with the corner tower of the castle. By means of a catapult the Burgundians succeeded in throwing combustibles on it, which obliged the defenders to abandon the tower, V, in haste. They were seen re-entering the castle just when the flames were beginning to consume the bridge. The roof of the tower, Q, was all but set on fire; and the defenders had great difficulty in arresting the progress of the flames. If Anseric had had five hundred more men he might from the central court have resumed the offensive at the moment when the Burgundians were trying to gain a lodgment in the western court. But he had lost a hundred men in the last engagement, and had no more soldiers than were absolutely necessary for the defence of the castle. In the evening the central part of the bailey was occupied by the Burgundians, who took up their quarters there, and intrenched themselves securely this time. Next morning, the 9th of June, the tower, M, being undermined, fell, and the breach, _c_, was proportionately widened. The ditch was filled up, and the tower, V, occupied by the Burgundians. The defenders, before they abandoned it, had set fire to the catapult mounted on the platform. The crown of the tower, Q, in the corner of the castle, rose more than twenty feet above the curtain, and thus hindered the Burgundians from moving at will on the rampart-walk of this curtain, which was not furnished with covered hoarding.
