'Item, for the better security of the observance of these articles by the Duke of Burgundy, the said duke of Brabant, the countess of Hainault and the aforesaid deputies, shall swear, as well in their own names and persons as on the part of the prelates, churchmen, nobility and principal towns of their country; that is to say, the said duke of Brabant, the countess of Hainault and the aforesaid deputies, shall swear, in the name of the said duke of Burgundy, for the whole country of Flanders, that the said duke of Burgundy will strictly observe and keep for ever this good peace, without doing himself, or procuring to be done by others, any act contrary to the true meaning and intent of it. In case the said duke of Burgundy shall, by open or secret means, do any thing against the tenour of this peace, then the aforesaid duke of Brabant and countess of Hainault do engage for themselves not to give him any advice, or assistance of men at arms or money, or in any manner whatever, seeing that the princes of the royal blood, the nobles, prelates, and capital towns in the kingdom, have taken a similar oath. 'The commissioners will also deliver good and sufficient bonds of security, according to the regulation of the king and his council; and they will promise, beside, to use their utmost endeavours that the nobles and others within the town of Arras shall loyally make the same oath; and likewise that all who may be at this present under the orders of the duke of Burgundy, or in his garrisons in Burgundy, Artois and Flanders, shall do the same when required by the king of France.' When the above articles had been properly drawn up, the different parties swore to their observance. The duke of Brabant, the countess of Hainault, and the flemish deputies, as being the friends and allies of the duke of Burgundy, first took the oath in the presence of the duke of Acquitaine, several princes of the blood, and the members of the king's council. The duke of Acquitaine then took a solemn oath to keep and preserve every article of the said peace: he then called to him Charles duke of Orleans, his cousin-german, and desired that he would take this oath; but the duke of Orleans, bowing low, replied,--'My lord, I am not bound to swear to it; for I only came, as a king's subject, to serve my lord the king and yourself.' 'Fair cousin, we beg that you will swear to the observance of this peace.' The duke of Orleans again said, 'My lord, I have not broken the peace, and ought not therefore to take the oath: I entreat you will be satisfied.' The duke of Acquitaine a third time required that he would swear,--and the duke of Orleans, with much anger, replied, 'My lord, I have not, nor have any of my council, broken the peace: make those who have broken it come hither and take the oath, and then I will obey your pleasure.'
