As soon as the Count of Campobasso arrived in the Duke of Lorraine’s army, the Germans sent him word to leave the camp immediately, for they would not entertain such traitors among them. Upon which message he retired with his party to Conde, a castle and pass not far off, where he fortified himself with carts and other things as well as he could, in hopes that, if the Duke of Burgundy were routed, he might have an opportunity of coming in for a share of the plunder, as he did afterward. Nor was this practice with the Duke of Lorraine the most execrable action that Campobasso was guilty of; but, before he left the army, he conspired with several other officers—finding it was impracticable to attempt anything against the Duke of Burgundy’s person—to leave him just as they came to the charge; for at that time he supposed it would put the army into the greatest terror and consternation; and if the Duke fled, he was sure he could not escape alive, for he had ordered thirteen or fourteen sure men, some to run as soon as the Germans came up to charge them, and others to watch the Duke of Burgundy and kill him in the rout; which was well enough contrived, for I myself have seen two or three of those who were thus employed to kill the Duke. Having thus settled his conspiracy at home, he went over to the Duke of Lorraine upon the approach of the German army; but, finding they would not entertain him, he retired to Conde, as I said before.
The German army marched forward, and with them a considerable body of French horse, whom the King had given leave to be present in that action. Several parties lay in ambush not far off, that, if the Duke of Burgundy were routed, they might surprise some person of quality or take some considerable booty. By this everyone may see into what a deplorable condition this poor Duke had brought himself by his contempt of good counsel. Both armies being joined, the Duke of Burgundy’s forces, which had been twice beaten before, and were weak and ill-provided besides, were quickly broken and entirely defeated. Many saved themselves by flight; the rest were either taken or killed; and among them the Duke of Burgundy himself was killed on the spot. Not having been in the battle myself, I will say nothing of the manner of his death; but I was told by some that they saw him beaten down, but, being prisoners themselves, were not able to assist him; yet, while they were in sight, he was not killed, but a great body of men coming that way afterward, they killed and stripped him in the throng, not knowing who he was. This battle was fought on January 5, 1476, upon the eve of Twelfth-day.
