The conference holden at Vilvorde was attended by the following personages: First, the king of England, the duke of Brabant, the earl of Hainault and his uncle, the duke of Gueldres, the earl of Juliers, the marquis of Blanckenberg, the marquis of Nuys, the earl of Mons, the lord Robert d'Artois, the lord of Fauquemont, the lord William de Dunort, the earl of Namur, Jacob van Arteveldt, and many other lords. Three or four men were sent by each of the principal towns of Flanders, Brabant and Hainault, by way of a council from them. The three countries of Flanders, Brabant and Hainault, there entered into a treaty, that thereafterward they would succor and assist each other in every possible case; that they formed an alliance, with covenants, that if either of the three was attacked by any one whatever, the other two would immediately come to his assistance; and if at any future period two of them should quarrel, then the third should settle the matters of difference between them. Many statutes were then sworn and agreed to, which afterwards turned out ill. But for a further confirmation of their love and friendship, they ordered coins to be struck, that should be current in these three countries, which were styled companions or allies. It was also determined, that the king of England should put himself in motion about Magdalen tide, and lay siege to the city of Tournay; and all the lords present promised to be there, as well as the forces from the principal towns: they then set off for their homes, to get ready and prepare themselves properly for the business.
