Buying of food and changing of money took place on ships, where the money-changers' tables were full of cash and objects in precious metals often sold by crusaders in exchange for Byzantine currency. A Flemish robber saw this, and was inflamed by greed for the wealth on display. With like-minded men, he seized objects of value and began a riot, forcing the Byzantine money-changers to flee for their lives, taking with them on the ships some crusaders who were bargaining for necessities. These were manhandled in revenge. Louis faced a complete breakdown in the provision of food. He demanded the guilty Fleming from the Count of Flanders, received him and hung him on the spot in full view of the City. He then had to deal with the money-changers and the captured crusaders. He demanded the return of everything stolen from the Byzantines, promising to pardon those who complied and hang those who did not. To avoid scaring the thieves, he asked for things to be returned to the bishop of Langres. The next day the money-changers returned, and received all they swore they had lost, Louis himself making up the shortfall. He sent envoys to Manuel I, Arnulf of Lisieux and Bartholomaios the Chancellor, to ask for the return of the captured crusaders and the renewal of a market. Arnulf and Bartholomaios went early to Manuel's palace, but were not seen that day, receiving neither food nor beds. In an audience the next day they found Manuel much less tractable than previously. Arnulf spoke with enough eloquence to persuade anyone but the poisonous snake Manuel had become, and succeeded in part: a market (albeit a scanty one) was provided, redress discussed for pilgrims who had lost possessions, and further meetings planned. But Arnulf had to leave as he was faint through lack of food
