While he was revolving the subject in his mind, there arrived in his capital of Susa, where he was then residing, a deserter from the army of Amasis in Egypt. The name of this deserter was Phanes. He was a Greek, having been the commander of a body of Greek troops who were employed by Amasis as auxiliaries in his army. He had had a quarrel with Amasis, and had fled to Persia, intending to join Cambyses in the expedition which he was contemplating, in order to revenge himself on the Egyptian king. Phanes said, in telling his story, that he had had a very narrow escape from Egypt; for, as soon as Amasis had heard that he had fled, he dispatched one of his swiftest vessels, a galley of three banks of oars, in hot pursuit of the fugitive. The galley overtook the vessel in which Phanes had taken passage just as it was landing in Asia Minor. The Egyptian officers seized it and made Phanes prisoner. They immediately began to make their preparations for the return voyage, putting Phanes, in the mean time, under the charge of guards, who were instructed to keep him very safely. Phanes, however, cultivated a good understanding with his guards, and presently invited them to drink wine with him. In the end, he got them intoxicated, and while they were in that state he made his escape from them, and then, traveling with great secrecy and caution until he was beyond their reach, he succeeded in making his way to Cambyses in Susa.

Information given by Phanes.
Treaty with the Arabian king.

Phanes gave Cambyses a great deal of information in respect to the geography of Egypt, the proper points of attack, the character and resources of the king, and communicated, likewise, a great many other particulars which it was very important that Cambyses should know. He recommended that Cambyses should proceed to Egypt by land, through Arabia; and that, in order to secure a safe passage, he should send first to the King of the Arabs, by a formal embassy, asking permission to cross his territories with an army, and engaging the Arabians to aid him, if possible, in the transit. Cambyses did this. The Arabs were very willing to join in any projected hostilities against the Egyptians; they offered Cambyses a free passage, and agreed to aid his army on their march. To the faithful fulfillment of these stipulations the Arab chief bound himself by a treaty, executed with the most solemn forms and ceremonies.

Plan for providing water.
Account of Herodotus.

The great difficulty to be encountered in traversing the deserts which Cambyses would have to cross on his way to Egypt was the want of water. To provide for this necessity, the king of the Arabs sent a vast number of camels into the desert, laden with great sacks or bags full of water. These camels were sent forward just before the army of Cambyses came on, and they deposited their supplies along the route at the points where they would be most needed. Herodotus, the Greek traveler, who made a journey into Egypt not a great many years after these transactions, and who wrote subsequently a full description of what he saw and heard there, gives an account of another method by which the Arab king was said to have conveyed water into the desert, and that was by a canal or pipe, made of the skins of oxen, which he laid along the ground, from a certain river of his dominions, to a distance of twelve days' journey over the sands! This story Herodotus says he did not believe, though elsewhere in the course of his history he gravely relates, as true history, a thousand tales infinitely more improbable than the idea of a leathern pipe or hose like this to serve for a conduit of water.

A great battle.
Defeat of the Egyptians.

By some means or other, at all events, the Arab chief provided supplies of water in the desert for Cambyses's army, and the troops made the passage safely. They arrived, at length, on the frontiers of Egypt.[A] Here they found that Amasis, the king, was dead, and Psammenitus, his son, had succeeded him. Psammenitus came forward to meet the invaders. A great battle was fought. The Egyptians were routed. Psammenitus fled up the Nile to the city of Memphis, taking with him such broken remnants of his army as he could get together after the battle, and feeling extremely incensed and exasperated against the invader. In fact, Cambyses had now no excuse or pretext whatever for waging such a war against Egypt. The monarch who had deceived his father was dead, and there had never been any cause of complaint against his son or against the Egyptian people. Psammenitus, therefore, regarded the invasion of Egypt by Cambyses as a wanton and wholly unjustifiable aggression, and he determined, in his own mind, that such invaders deserved no mercy, and that he would show them none. Soon after this, a galley on the river, belonging to Cambyses, containing a crew of two hundred men, fell into his hands. The Egyptians, in their rage, tore these Persians all to pieces. This exasperated Cambyses in his turn, and the war went on, attended by the most atrocious cruelties on both sides.

Inhuman conduct of Cambyses.

In fact, Cambyses, in this Egyptian campaign, pursued such a career of inhuman and reckless folly, that people at last considered him insane. He began with some small semblance of moderation, but he proceeded, in the end, to the perpetration of the most terrible excesses of violence and wrong.
