The placing of the flag of one of the crusading leaders upon castle or town was usually sufficient to protect that place from further assault, but it was not always respected. On the capture of Jerusalem in July, 1099, a remnant of the wretched inhabitants who had escaped torture and massacre at the hands of the Christians, had taken refuge on the roof of the mosque which occupied the site of Solomon's Temple. Tancred, moved by pity, wished to spare them, and he and Gaston de Bearn gave them their gonfanons as a protection. This served them for a few hours, but the Crusaders had not tasted enough blood, and early next morning, ignoring the protection thus formally granted, they shot them down with arrows or put them to the sword--men and women alike. Raymond and Tancred had in a like manner given protection to the defenders of the Tower of David, who received their flags "as a sign of protection and life." Raymond was more successful, perhaps because the Tower of David was not so easily entered, and he succeeded in getting the prisoners away safely, thereby giving rise to the scandalous imputation that he had neglected his duty and sold his protection for gold. Our last instance of the use of the flag during this (the first) Crusade will concern its employment at sea. In May, 1102, Jaffa was being threatened by the Saracens, and Baldwin, then King of Jerusalem, was anxious to encourage the inhabitants to hold out. The Saracen forces prevented him from getting there by land; he therefore embarked at Arsuf in a buss, together with one Goderic, who is described by Albert of Aix as an English pirate. On approaching Jaffa the flag of Baldwin was fastened to a spear and raised high in the sun, so that the Christians in Jaffa, on seeing it, might be sure that Baldwin was still living. The Saracens also recognised it, and hastily collecting a force of twenty galleys and thirteen other craft, attempted to sink the buss. The king, however, got through in safety.
