John of Cornwall vs. the Seneschal of Hainault 1409

The other field was prepared for the seneschal of Hainault to meet with sir John of Cornwall, an English knight of great renown who was married to the sister of the king of England. The two knights had undertaken to do their arms before the duke of Burgundy, only to show their prowess: to run certain lance-strokes against each and also to do some strokes with axe and sword. But when the duke of Burgundy had prepared the field where they were to accomplish it, the two champions were required to go to Paris to perform their enterprise before the king. And there, after the ordinances were done and the day had come, Cornwall entered the field with great pomp, riding on his destrier until he came right before the king where he bowed and saluted him most humbly. And after him came six little pages on destriers, the first two covered with ermine and the following four covered with cloth of gold, and after they had entered the lists the pages left the field.

And afterwards came the seneschal, accompanied by the brothers Duke Anthoine de Brabant and Philip, count of Nevers on foot each holding the bridle of his horse, one an the right and the other on the left. And the count of Clermont carried his axe, and the count of Penthievre his lance.

And after he had entered the field and done his reverence to the king in the same way as Cornwall they both prepared to joust together with sharp lances. But before they began their run it was cried by the king that they should cease and go no further in doing their arms and that none in the realm, under penalty of death, should challenge another in the field without reasonable cause.

And after the king had grandly feasted and honored the two knights in his court they both departed, and it was said in England that they did so with the intent of performing and accomplishing their arms.
