Tancred, the bravest, if not the best, of all, was to follow within a very few years, and Baldwin found himself for the last six years of his reign without a single one of the old princes, except his cousin, Baldwin du Bourg, to quarrel with, to help, or to look to for help. And, still more to complicate matters, the crusade, which the ambition of Bohemond had directed against the Greek Empire for his own purposes, had alienated the sympathies, such as they were, and the assistance of the Greek Empire, and deprived the Christian Kingdom of every hope from that quarter. Then Tancred and Baldwin du Bourg, as soon as the latter got his release from captivity, began to quarrel, and, turn by turn, called in the assistance of the Saracens. They were persuaded to desist by the exhortations of the king, who told Tancred plainly that unless he ceased to make war against Christians, all the Christians in the East would make common cause against him. The only resources left to the king were those derived from the constant influx of pilgrims, and therefore of fighting men, and the assistance he derived from the annual visit of the Genoese and Pisan fleets; these came, actuated solely by the desire for merchandise and plunder. In return for concessions and the chance of booty, they fought the Egyptian fleets, and co-operated with Baldwin in his operations against sea-side places. Thus, in 1104, after an unsuccessful attempt upon the town, Baldwin took advantage of the presence of sixty-six Genoese galleys to lay siege to Acre. He invited them to assist him in his enterprise, first, for the love of Christ, and secondly, in the hope of reaping a golden harvest out of victory. The Genoese consented, on the condition of receiving a third of the revenue, and perpetual rights which would be obtained by the capture of the place, and of a street being entirely given up to themselves, where they might exercise their own laws and justice. These conditions, exorbitant as they were, were accepted, and siege was laid in due form, Baldwin investing the place by land and the Genoese by sea. The time was almost gone by for unconditional surrender and capture by assault, and the Christians fought with machines and rams for twenty days before the enemy capitulated. And it was then only on honourable terms. The inhabitants were to take out their wives, families, and whatever they could carry. Those who preferred to remain behind were to be allowed to continue in the peaceful occupation of their homes, on condition of paying an annual tribute to the king. It will be seen that a short space of five years had already materially altered the relative positions of Christians and Mohammedans. The conditions were ill kept, for a large number of the Saracens were massacred by the unruly sailors, and Baldwin seems to have been powerless to interfere. This was, however, a most important position, and threw open a convenient harbour for the Genoese.
