power, and bring the war to an end at a blow. He came so quickly, that, as Herodotus says, he announced his own arrival. The sudden appearance of the Persian army in the neighbourhood of Sardis completely startled and terrified Crœsus. He retired in order to be able to place in the field a number of warriors equal to the army of Cyrus, and now he was compelled to shut himself up in the walls of Sardis or fight with far smaller numbers than took the field at Pteria. He chose the latter, and awaited the attack on the plain of the Hermus, which was large enough to provide a field for his excellent cavalry.

Though he had a great advantage in his forces, and in the consciousness of his superiority to his enemy, Cyrus omitted no means for securing the victory. He had experienced at Pteria the attack of the Lydian horse, their superiority to his own cavalry, in spite of the practice in riding which the Persians underwent from their youth up, and the excellence of the Median horse. To render useless the attack of these horsemen, Cyrus caused the camels which carried the baggage and supplies of his army to be mounted, and placed them in the first line. This arrangement is mentioned not only by Herodotus but also by Xenophon. No doubt the Lydian horse would be frightened by the noise and unwonted aspect of these animals. Though robbed of their best arm and mode of fighting, the Lydians nevertheless resolved to dismount and carry on the battle on foot. They pressed courageously on the Persians, and could only be driven into the gates of Sardis after a bloody battle. Crœsus was now limited to the walls of his city, and compelled to defend them. He hoped to be able to hold the city till his confederates should come, to whom on the approach of Cyrus he had sent with appeals for immediate assistance. But on the fourteenth day after the investment of the city, as Herodotus maintains, Cyrus brought matters to a decision. Then the Mardian climbed the steep rock on the Pactolus, on which the citadel lay, at a place where no guard was set, the citadel and city were taken, and Crœsus became a prisoner. A picture at Pompeii exhibits Cyrus before his tent, and Harpagus beside him, at the moment when Crœsus is brought forward.

Herodotus' narrative of the ascent of the citadel of Sardis is confirmed by a precisely analogous incident which took place more than three centuries later. Antiochus III. had besieged his brother-in-law Achæus for more than a year in Sardis, and in vain. All hope of taking the city except by starvation was given up, when Lagoras, a Cretan, observed that the walls must be left without a guard where the citadel and the city met. At this point the walls rose on steep rocks above a cleft into which the besieged threw from the towers their dead along with the carcasses of beasts of burden and horses. As the birds of prey when they had eaten the corpses settled on the walls, Lagoras concluded that no guards were stationed there. By night he examined whether it was quite impossible to climb up and plant scaling-ladders there. When he discovered a ravine by which this seemed practicable, he acquainted the king. The necessary preparations were made; in the night, towards morning, when the moon had set, Lagoras with sixteen companions climbed up the rocks; 2000 men were ready to support him. The spur on which the wall lay was so steep that even when the morning broke a jutting piece of rock prevented the garrison from seeing what was going on, and when Antiochus led his army against the Persian gate the garrison went to meet them. Meanwhile the assailants by means of two ladders scaled the walls close against the citadel and opened the nearest door; the confusion which ensued put the city in the hands of Antiochus after a short struggle. Yet Achæus maintained the citadel; by a secret steep and dangerous path in the rear he was able to keep up a communication with Ptolemy Philopator of Egypt, and finally he attempted to escape by this means, but he was betrayed and fell into the hands of Antiochus (213 B.C.).[25]
