Year after year an army came from Egypt and attempted an invasion of Palestine, using Ascalon as the basis of operations and the depôt of supplies. But every year the attack grew more feeble and the rout of the Egyptians more easy. The next important place attacked by the help of the Genoese was Tripoli. After the death of Count Raymond, his affairs in the East were conducted by his nephew, William of Cerdagne, until Bertram, Raymond’s son, should arrive. He came in 1109, and immediately began to quarrel with his cousin, who called in the aid of Tancred. Baldwin, however, interfered and substituted a settlement of all the disputed points between them. By his arrangement William kept all the places he had himself conquered, and Bertram had the rest. Moreover, if either died without heirs, Bertram was to have all. A short time after, William was accidentally killed by an arrow in trying to settle a quarrel among his men at arms, and tranquillity among the princes was assured. Operations, meantime, had been going on against the little town of Biblios, which succumbed, after a show of resistance, on the same terms as those obtained by the people of Acre. The strong places which still held out were Tripoli, Tyre, Sidon, Beyrout, and Ascalon. Baldwin’s plan was to take them in detail, and always by the aid of the Genoese fleet. He joined his forces to those of Bertram, and the siege of Tripoli was vigorously taken in hand. It illustrates the untrustworthy character of the materials from which a history of this kingdom has to be drawn that Albert of Aix, one of the most careful of the chroniclers, absolutely passes over the capture of this important place in silence. The inhabitants defended themselves as well as they were able, but seeing no hope of assistance they capitulated on conditions of safety. These were granted, but pending the negotiations, the savage Genoese sailors, getting over the wall by means of ladders and ropes, began to slaughter the people. “Every Saracen,” says Foulcher de Chartres, who has a touch of humour, “who fell into their hands, experienced no worse misfortune than to lose his head; and although this was done without the knowledge of the chiefs, the heads thus lost could not be afterwards put on again.” All the chronicles but one agree in preserving silence over a barbarism almost worse than the breaking of a treaty. It was this: the Christians found in Tripoli a splendid library. It had been collected in the course of many peaceful years by the family of Ibn-Ammar, who were the hereditary princes, under the Caliph of Cairo, of the place. It consisted of a hundred thousand volumes, and a wretched priest blundering into the place, and finding this enormous mass of books written in “execrable,” because unknown characters, called in the assistance of soldiers as ignorant as himself, and destroyed them all. The Tripolitans had, many years before, placed themselves under the protection of the Egyptian Caliph.
