Pompey raised and equipped a vast number of galleys, and divided them into separate fleets, putting each one under the command of a lieutenant. He then divided the Mediterranean Sea into thirteen districts, and appointed a lieutenant and his fleet for each one of them as a guard. After sending these detachments forth to their respective stations, he set out from the city himself to take charge of the operations which he was to conduct in person. The people followed him, as he went to the place where he was to embark, in great crowds, and with long and loud acclamations. [Sidenote: Pompey drives the pirates before him.] [Sidenote: Exultation at Rome.] Beginning at the Straits of Gibraltar, Pompey cruised with a powerful fleet toward the east, driving the pirates before him, the lieutenants, who were stationed along the coast being on the alert to prevent them from finding any places of retreat or refuge. Some of the pirates' ships were surrounded and taken. Others fled, and were followed by Pompey's ships until they had passed beyond the coasts of Sicily, and the seas between the Italian and African shores. The communication was now open again to the grain-growing countries south of Rome, and large supplies of food were immediately poured into the city. The whole population was, of course, filled with exultation and joy at receiving such welcome proofs that Pompey was successfully accomplishing the work they had assigned him. [Sidenote: The pirates concentrate themselves.] The Italian peninsula and the island of Sicily, which are, in fact, a projection from the northern shores of the Mediterranean, with a salient angle of the coast nearly opposite to them on the African side, form a sort of strait which divides this great sea into two separate bodies of water, and the pirates were now driven entirely out of the western division. Pompey sent his principal fleet after them, with orders to pass around the island of Sicily and the south era part of Italy to Brundusium, which was the great port on the western side of Italy. He himself was to cross the peninsula by land, taking Rome in his way, and afterward to join the fleet at Brundusium. The pirates, in the mean time, so far as they had escaped Pompey's cruisers, had retreated to the seas in the neighborhood of Cilicia, and were concentrating their forces there in preparation for the final struggle. Pompey was received at Rome with the utmost enthusiasm. The people came out in throngs to meet him as he approached the city, and welcomed him with loud acclamations. He did not, however, remain in the city to enjoy these honors. He procured, as soon as possible, what was necessary for the further prosecution of his work, and went on. He found his fleet at Brundusium, and, immediately embarking, he put to sea. [Sidenote: Some of them surrender.]
