This breach of faith might prove very injurious to the enterprise; but what most grieved the princes and barons assembled at Venice, was the impossibility of fulfilling their engagements with the republic without the concurrence of their unfaithful companions. They sent messengers into all parts to warn the Crusaders that had set out, and to implore them to join the main army; but whether most of the pilgrims were dissatisfied with the agreement entered into with the Venetians, or whether it appeared to them more convenient and safe to embark at ports in their own vicinity, a very small number of them could be prevailed upon to repair to Venice. Those who were already in that city, were neither sufficiently numerous nor sufficiently rich to pay the promised amount, or fulfil the engagements made in their names. Although the Venetians were more interested in the crusade than the French knights, as they possessed a part of the cities of Tyre and Ptolemaïs, which they were going to defend, they were unwilling to make any sacrifice, and the barons, on their side, were too proud to ask any favour, or to solicit the Venetians to change or moderate the conditions of the treaty. Each of the Crusaders was required to pay the price of his passage. The rich paid for the poor; soldiers as well as knights being eager to give all the money they possessed, persuaded, they said, that God was powerful enough to return it to them a hundred-fold, when it should please him. The count of Flanders, the counts of Blois and St. Paul, the marquis of Montferrat, and several other leaders despoiled themselves of their plate, their jewels, and everything they had that was most valuable,[72] and only retained their horses and arms. Notwithstanding this noble sacrifice, the Crusaders still were indebted to the republic a sum of fifty thousand silver marks. The doge then assembled the people, and represented to them that it was not honourable to employ too much rigour, and proposed to demand of the Crusaders the assistance of their army for the republic, until they could discharge their debt.
