On the morning of the 7th of June the defenders were still in possession of the retrenchment C, of that marked A A, and of the barricade B; at H a strong palisade, with a _bretèche_, had been erected before the entrance at the very commencement of the siege. At D' another palisade arose in front of the ditch; at E was a second retrenchment, before the postern entrance; and at G a strong barricade. The building, F, part of the old Roman construction, crenelated at the top, might hold out for some time. The towers, V, M, _m_, _m'_, and V' were still in the hands of the defenders, and could take the assailants in the rear, should they attempt to enter the chapel, I, and the stables, D, that had been burned.
Anseric and his uncle came to the determination to abandon the retrenchment, A A. To defend it was only to lose men, since the enemy could not venture into the return formed by the two towers of the gate and the building F. It was preferable to direct all their efforts to C, for this was evidently the point of attack.
About five o'clock in the morning, therefore, the retrenchment, A A, was abandoned; and in fact the Burgundians contented themselves with making gaps in it without advancing further. In the early morning the duke had directed a quantity of burning darts on the roof of the tower, M; but the catapult planted by the defenders on that of the angle, V, greatly annoyed the assailants grouped outside, who were preparing to make a vigorous attack through the breach C.
It was about noon that the duke gave orders for a simultaneous attack on two points; the roof of the tower, M, was already on fire. The first attack was vigorously directed to the retrenchment C. The second made a gap in the crenelated walls of the chapel, the intention being to get possession of the palisade E. At the same time, two catapults planted outside were showering burning darts upon the roofs of the towers _m_, _n'_ and V, while a trebuchet was destroying the hoarding and battlements with volleys of stones.
The defenders posted on the summit of the tower, V, by discharging stones and quarrels on the flanks of the assailants, who were impetuously assaulting the retrenchment, C, did them much damage, their bucklers not availing to protect them in front and flank; and from the narrow front of the castle, skilful archers discharged arrows in abundance over the heads of their own party on the assailants who presented themselves at the breach, C; for they were within bowshot.
