The ambiguity of the crusaders' command structure would prove to be crucial in the final outcome. While Nevers was given a long list of "counselors", as well as another list of prominent French lords on the crusade with whom Nevers could consult "when it seemed good to him", the concept of unity of command was not yet embraced by medieval warriors.[25] Rules of discipline for the crusade were decreed at a War Council on 28 March 1396, which included the final provision, "Item, that [in battle] the Count and his company claim the avante garde," revealing that the chivalric code continued to require knights to prove their valor by leading the charge.[26]
