Richard also exacted of Philip a solemn oath, that when he had returned to France he would not, in any way, molest or invade any of his--that is, Richard's--possessions, or make war against any of his vassals or allies. This agreement was to continue in force, and to be binding upon Philip until forty days after Richard should have himself returned from the Crusade. These things being all thus arranged, Philip began to make his preparations openly for embarking on his voyage home. The knights and barons, and indeed the whole body of the army, considered Philip's leaving them as a very culpable abandonment of the enterprise, and they crowded around the place of embarkation when he went on board his vessel, and manifested their displeasure with ill-suppressed hisses and groans. * * * * * The time which had been fixed upon for Saladin to comply with the stipulations of the surrender was forty days, and this period was now, after Philip had gone, drawing rapidly to a close. Saladin found that he could not fulfill the conditions to which he had agreed. As the day approached he made various excuses and apologies to Richard, and he also sent him a number of costly presents, hoping, perhaps, in that way to propitiate his favor, and prevent his insisting on the execution of the dreadful penalty which had been agreed upon in case of default, namely, the slaughter of the five thousand hostages which had been left in his hands. The time at last expired, and the treaty had not been fulfilled. Richard, without waiting even a day, determined that the hostages should be slain. A rumor was set in circulation that Saladin had put to death all his Christian prisoners. This rumor was false, but it served its purpose of exasperating the minds of the Crusaders, so as to bring the soldiers up well to the necessary pitch of ferocity for executing so terrible a work. The slaughter of five thousand defenseless and unresisting men, in cold blood, is a very hard work for even soldiers to perform, and if such a work is to be done, it is always necessary to contrive some means of heating the blood of the executioners in order to insure the accomplishment of it. In this case, the rumor that Saladin had murdered his Christian prisoners was more than sufficient. It wrought up the allied army to such a phrensy that the soldiers assembled in crowds, and riotously demanded that the Saracen prisoners should be given up to them, in order that they might have their revenge.
