At length, however, the time arrived when the march must be commenced. Richard had learned, by means of scouts and spies which he sent out, that Saladin was moving to the southward and westward--retreating, in fact, toward Jerusalem, which was, of course, the great point that he wished to defend. That, indeed, was the great point of attack, for the main object which the Crusaders proposed to themselves in invading Palestine was to get possession of the sepulchre where Christ was buried at Jerusalem. The recovery of the Holy Sepulchre was the watchword; and among all the people who were watching the progress of the enterprise with so much solicitude, and also among the Crusaders themselves, the progress that was made was valued just in proportion as it tended to the accomplishment of this end. Richard set apart a sufficient number of troops for a garrison to hold and defend Acre, and then, on taking a census of the remainder of his force, found that he had thirty thousand men to march with in pursuit of Saladin. He arranged this force in five divisions, and placed each under the command of a competent general. There were two very celebrated bodies of knights that occupied positions of honor in this march. They were the Knights Templars and the Knights of St. John, or Hospitalers, the order that has been described in a previous chapter of this volume. The Templars led the van of the army, and the Hospitalers brought up the rear. The march was commenced on the twenty-second of August, which was not far from two months from the time that Acre was surrendered. The course which the army was to take was at first to follow the sea-shore toward the southward to Jaffa, a port nearly opposite to Jerusalem. It was deemed necessary to take possession of Jaffa before going into the interior; and, besides, by moving on along the coast, the ships and galleys containing the stores for the army could accompany them, and supply them abundantly, from time to time, as they might require. By this course, too, they would be drawing nearer to Jerusalem, though not directly approaching it. The arrangements connected with the march of the army were conducted with great ceremony and parade. The knights wore their costly armor, and were mounted on horses splendidly equipped and caparisoned. In many cases the horses themselves were protected, like the riders, with an armor of steel. The columns were preceded by trumpeters, who awakened innumerable echoes from the mountains, and from the cliffs of the shore, with their animating and exciting music, and innumerable flags and banners, with the most gorgeous decorations, were waving in the air. When the expedition halted at night, heralds passed through the several camps to the sound of trumpets, and pausing at each one, and giving a signal, all the soldiers in the camp kneeled down upon the ground, when the heralds proclaimed in a loud voice three times, GOD SAVE THE HOLY SEPULCHRE, and all the soldiers said Amen.
