That was the sum and substance of all that Marie could cajole them into granting. Meanwhile, Louis was making ready to seize Burgundy and Picardy, advancing now one pretext, now another, for his acts, seeking to give every seizure the appearance of legality, but bent on seizing, right or wrong. Marie despatched two of her father's oldest advisers, the chancellor Hugonet and the lord of Humbercourt, as ambassadors to Louis, to delay his proceedings. Though faithful to the interests of their duchess, Hugonet and Humbercourt were no match for the crafty king. He had already tampered with other servants of Burgundy, and had found few who could not be made to see that French gold or French titles were better worth considering than any favors received from a master who could no longer reward. Of this class was the Lord of Crèvecoeur, whose mother had been the guardian of the young duchess when she had no mother, and to whom one of the most important charges in Burgundy had been deputed, the governorship of Picardy and of the towns on the Somme. Crèvecoeur was a knight of the Toison d'Or, and had received countless other favors from Charles, whose daughter he was now willing to betray. What Louis most desired was Arras; this my Lord of Crèvecoeur held for Burgundy; might there not be found some legal subterfuge or quibble authorizing him to hold it for the king? Louis cajoled, entreated, almost menaced, the Burgundian envoys, till they, thinking he would have Arras anyway, yielded so far as to issue an order to Crèvecoeur, signed by the chancellor, Hugonet, authorizing him to open the gates of the town to the king. Louis entered Arras on March 4th, and Marie soon found that her troubles had but just begun.
