The neighbourhood of Jerusalem was covered with light brushwood, but there were no trees; there had been grass in plenty, but it was dried up by the summer sun; there were wells and cisterns, but they had all been closed,—“the fountains were sealed.” Only the pool of Siloam was accessible to the Crusaders; this was intermittent and irregular, and its supply, when it did flow, was miserably inadequate for a host of forty thousand. Moreover, its waters were brackish and disagreeable. And the camp was full of sick, wounded, and helpless. On the west, east, and south sides of the city no attack was possible, on account of the valleys by which it was naturally protected. The Crusaders pitched their camp in the north. First in the post of danger, as usual, was the camp of Godfrey, Duke of Lorraine. His position extended westwards from the valley of Jehoshaphat, along the north wall. Next to him came the Count of Flanders; next, Robert of Normandy, near whom was Edgar Atheling with his English; at the north-west angle was Tancred; and lastly, the camp of the Count of Toulouse extended along the west as far as the Jaffa Gate. Later on, however, Raymond moved a portion of his camp to that part of Mount Sion stretching south of the modern wall. But the only place where an attacking party could hope for success was on the north. Bohemond was not with the army. He cared less about taking the city than wreaking his vengeance upon the Greek emperor. Meantime, within the city was an army of forty thousand men. Provisions for a long siege had been conveyed into the town; the zeal of the defenders had been raised by the exhortations of the Imams; the walls were strengthened and the moats deepened. Communication and relief were possible from the east, where only scattered bands of the Christians barred the way.
