'Item, the king consents to grant letters, that in case he shall violate the articles of the present treaty, his vassals and subjects shall be no longer bound to obey and serve him, but shall be obliged to serve and assist the duke of Burgundy and his successors against him. In this case, all his subjects shall be absolved from their oaths of fidelity toward king Charles, Without at any time hereafter being called to account for so doing; and from this moment king Charles absolves them from all fidelity to him, in case such violation of the treaty shall take place,—and that the duke of Burgundy shall do the same in regard to his vassals and subjects.
'Item, all these promises, obligations, and submissions, of king Charles, respecting the due fulfilment of this treaty, shall be made before the lord cardinal of Santa Croce, legate from the holy father the pope, the lord cardinal of Cyprus, and the other ambassadors from the holy council of Basil, in the most ample manner that can be devised, and on pain of excommunications, interdicts, and all the most weighty punishments of the church, to the utmost power which the said lords cardinals may possess from the pope, provided that the duke of Burgundy shall act in a similar manner.
'Item, the king will give to the duke of Burgundy not only his own declaration, sealed with his seal, but the declarations and seals of the princes of his blood and under his obedience,—namely, the seals of the duke of Anjou, his brother the lord Charles, the duke of Bourbon, the count of Richemont, the count of Vendôme, the count of Foix, the count of Auvergne, the count of Perdiac, and others,—which declarations of the princes shall be incorporated with that of the king, who shall with them promise faithfully to maintain the contents of the said declarations; and should they be infringed on the part of the king, they do severally promise to aid and assist the said duke of Burgundy and his friends against the king. In like manner shall the duke of Burgundy deliver in his declarations.
'Item, the king shall also cause to be given to the duke of Burgundy similar declarations under the seals of such churchmen, nobles, and principal towns of the realm under the king's obedience as the duke of Burgundy shall name, under penalties both corporal and pecuniary on failure, together with such securities for the due performance of their engagements as the lords cardinals and prelates commissioned by the pope may think proper and advisable.
'Item, should it happen hereafter that omissions, infractions, or attempts to infringe any of the said articles should arise, notwithstanding the present treaty, they shall remain in full force and vigour, and the peace shall not be considered as broken or annulled; but such omissions, infractions and attempts, shall be instantly amended and corrected, according to the virtual meaning of what has been before declared,—and the guarantees thereof shall see that it be done.
'Item, as we have been again earnestly exhorted and pressed by the said cardinals, and by the ambassadors from the holy council, to incline our ears and attend to the proposals made to us respecting a peace,—which proposals they think just and reasonable, and such as ought not to be refused by us,—remonstrating also with us, that we should make peace with king Charles of France from our love to God, and according to reason and honour, notwithstanding any alliances, oaths or engagements entered into with our very beloved and dear lord the king of England lately deceased,—the said cardinals and others, ambassadors from the holy council of Basil, urging us to a compliance by many reasons and arguments,—
'We, therefore, principally through reverence to God, and from the pity and compassion we feel for the poor people of France, who have been such great sufferers in these troubles and divisions within that realm, and in compliance with the admonitions and urgent entreaties of the said cardinals, and the ambassadors from our holy father the pope and the council, which we consider as commands to a catholic prince and obedient son of the church, have, after calling to our aid and council the highest lords of our blood and lineage, with others of our most faithful vassals and counsellors, made for ourselves and our successors a firm, loyal, and solid peace and re-union with our lord the king and his successors, according to the tenour of the articles above recited, which, on the part of the said king, he and his successors are bounden to fulfil toward us.
'The whole of these articles, so far as they regard us, we approve of and accept; and from this moment consent to and make all the renunciations, promises, submissions, and every other concession demanded from us in the above articles; and we acknowledge our aforesaid lord king Charles of France as our sovereign lord, in as much as regards the lands and lordships we hold in that kingdom, promising for ourself and our heirs on our faith and bodily oath, on the word of a prince, on our honour, and on the loss of our expectations in this world and in that to come, to hold inviolate this treaty of peace, and the whole of the articles contained in the said treaty, without attempting to invalidate the same either by word or deed, openly or secretly.
'For the further maintenance of this peace by ourself, and by all others, we submit ourself and them to whatever regulations and ordinances it may please our holy father the pope, and the holy council now assembled at Basil, to promulgate by the lords cardinals and the ambassadors from the said council now present; and we are willing to suffer any censures from the church, should we fail in the due fulfilment of all the articles contained in the said treaty. We renounce all exemptions, whatever may be alleged to the contrary, more particularly to that rule in law which declares that a general renunciation is not equally valid with an especial one, the whole to be fulfilled without fraud, deceit, or any chicanery whatever.
'That this treaty may have every due formality, and be perfectly stable, we have caused our signet to be affixed to these presents. Given at our town of Arras the 21st day of September, in the year 1435.' It was also signed by the duke of Burgundy, in the presence of his council.
