Having placed Ascalon in a condition of defence, Richard restored other fortifications destroyed by Saladin along the coast. These works, however, were attended with a vast expense, and Richard's generosity, which appears to have been without stint, whether much or little was at his command, hastened the exhaustion of his finances. The French and other foreign troops attached to his army were kept together by the largesses he gave them; but as the treasury became empty they relaxed in their obedience, and their national animosities found vent in repeated quarrels and disturbances. The dispute between Conrad of Montferrat and Guy of Lusignan for the crown of Jerusalem was renewed. Conrad, whose character was vacillating and treacherous, was nevertheless a man of considerable ability and of high military renown. Having secured the assistance of the Genoese, he defied the power of the King of England, and a civil war appeared to be imminent among the Christians of Palestine. The Pisans, whose old hatred against the Genoese led them to take the opposite side, declared for Lusignan, and frequent combats took place in the very streets of Acre between the opposing factions. Richard quitted Ascalon, and succeeded in repressing these tumults. He endeavoured to restore unanimity to the army, and to conciliate the Marquis of Montferrat; but that haughty chief rejected his offers, and entrenched himself in the town of Tyre, with a number of disaffected soldiers of different nations who had joined his standard. Saladin soon became aware of the dissensions in the Christian army, and he made preparations for striking what he hoped would be a decisive and successful blow. But in the meanwhile he was unexpectedly met by proposals for peace from Cœur-de-Lion, who sent him word that he demanded only the possession of Jerusalem and the wood of the true Cross. The soldan returned for answer that the blessed city[39] was as dear to the Moslem as to the Christian, and would never be delivered up except by force.
