Such was the state of fears and hopes on both sides, at the time when Tissaphernes left the Greeks, after concluding his convention. For twenty days did they await his return, without receiving from him any communication; the Cyreian Persians under Ariæus being encamped near them. Such prolonged and unexplained delay became, after a few days, the source of much uneasiness to the Greeks; the more so as Ariæus received during this interval several visits from his Persian kinsmen, and friendly messages from the king, promising amnesty for his recent services under Cyrus. Of these messages the effects were painfully felt in manifest coldness of demeanor on the part of his Persian troops towards the Greeks. Impatient and suspicious, the Greek soldiers impressed upon Klearchus their fears, that the king had concluded the recent convention only to arrest their movements, until he should have assembled a larger army and blocked up more effectually the roads against their return. To this Klearchus replied,—“I am aware of all that you say. Yet if we now strike our tents, it will be a breach of the convention and a declaration of war. No one will furnish us with provisions; we shall have no guides; Ariæus will desert us forthwith, so that we shall have his troops as enemies instead of friends. Whether there be any other river for us to cross, I know not; but we know that the Euphrates itself can never be crossed, if there be an enemy to resist us. Nor have we any cavalry,—while cavalry is the best and most numerous force of our enemies. If the king, having all these advantages, really wishes to destroy us, I do not know why he should falsely exchange all these oaths and solemnities, and thus make his own word worthless in the eyes both of Greeks and barbarians.”[119]

Such words from Klearchus are remarkable, as they testify his own complete despair of the situation,—certainly a very natural despair,—except by amicable dealing with the Persians; and also his ignorance of geography and the country to be traversed. This feeling helps to explain his imprudent confidence afterwards in Tissaphernes.

That satrap, however, after twenty days, at last came back, with his army prepared to return to Ionia,—with the king’s daughter whom he had just received in marriage,—and with another grandee named Orontas. Tissaphernes took the conduct of the march, providing supplies for the Greek troops to purchase; while Ariæus and his division now separated themselves altogether from the Greeks, and became intermingled with the other Persians. Klearchus and the Greeks followed them, at the distance of about three miles in the rear, with a separate guide for themselves; not without jealousy and mistrust, sometimes shown in individual conflicts, while collecting wood or forage, between them and the Persians of Ariæus. After three days’ march (that is, apparently, three days, calculated from the moment when they began their retreat with Ariæus) they came to the Wall of Media, and passed through it,[120] prosecuting their march onward through the country on its other or interior side. It was of bricks cemented with bitumen, one hundred feet high, and twenty feet broad; it was said to extend a length of twenty parasangs (or about seventy miles, if we reckon the parasang at thirty stadia), and to be not far distant from Babylon. Two days of farther march, computed as eight parasangs, brought them to the Tigris. During these two days they crossed two great ship canals, one of them over a permanent bridge, the other over a temporary bridge laid on seven boats. Canals of such magnitude must probably have been two among the four stated by Xenophon to be drawn from the river Tigris, each of them a parasang distant from the other. They were one hundred feet broad, and deep enough even for heavy vessels; they were distributed by means of numerous smaller channels and ditches for the irrigation of the soil; and they were said to fall into the Euphrates; or rather, perhaps, they terminated in one main larger canal cut directly from the Euphrates to the Tigris, each of them joining this larger canal at a different point of its course. Within less than two miles of the Tigris was a large and populous city named Sittakê, near which the Greeks pitched their camp, on the verge of a beautiful park or thick grove full of all kinds of trees; while the Persians all crossed the Tigris, at the neighboring bridge.

As Proxenus and Xenophon were here walking in front of the camp after supper, a man was brought up who had asked for the former at the advanced posts. This man said that he came with instructions from Ariæus. He advised the Greeks to be on their guard, as there were troops concealed in the adjoining grove, for the purpose of attacking them during the night,—and also to send and occupy the bridge over the Tigris, since Tissaphernes intended to break it down, in order that the Greeks might be caught without possibility of escape between the river and the canal. On discussing this information with Klearchus, who was much alarmed by it, a young Greek present remarked that the two matters stated by the informant contradicted each other; for that if Tissaphernes intended to attack the Greeks during the night, he would not break down the bridge, so as both to prevent his own troops on the other side from crossing to aid, and to deprive those on this side of all retreat if they were beaten,—while, if the Greeks were beaten, there was no escape open to them, whether the bridge continued or not. This remark induced Klearchus to ask the messenger, what was the extent of ground between the Tigris and the canal. The messenger replied, that it was a great extent of country, comprising many large cities and villages. Reflecting on this communication, the Greek officers came to the conclusion that the message was a stratagem on the part of Tissaphernes to frighten them and accelerate their passage across the Tigris; under the apprehension that they might conceive the plan of seizing or breaking the bridge and occupying a permanent position in the spot where they were; which was an island, fortified on one side by the Tigris,—on the other sides, by intersecting canals between the Euphrates and the Tigris.[121] Such an island was a defensible position, having a most productive territory with numerous cultivators, so as to furnish shelter and means of hostility for all the king’s enemies. Tissaphernes calculated that the message now delivered would induce the Greeks to become alarmed with their actual position and to cross the Tigris with as little delay as possible. At least this was the interpretation which the Greek officers put upon his proceeding; an interpretation highly plausible, since, in order to reach the bridge over the Tigris, he had been obliged to conduct the Greek troops into a position sufficiently tempting for them to hold,—and since he knew that his own purposes were purely treacherous. But the Greeks, officers as well as soldiers, were animated only by the wish of reaching home. They trusted, though not without misgivings, in the promise of Tissaphernes to conduct them; and never for a moment thought of taking permanent post in this fertile island. They did not, however, neglect the precaution of sending a guard during the night to the bridge over the Tigris, which no enemy came to assail. On the next morning they passed over it in a body, in cautious and mistrustful array, and found themselves on the eastern bank of the Tigris,—not only without attack, but even without sight of a single Persian, except Glus, the interpreter, and a few others watching their motions.

After having crossed by a bridge laid upon thirty-seven pontoons, the Greeks continued their march to the northward upon the eastern side of the Tigris, for four days, to the river Physkus; said to be twenty parasangs.[122] The Physkus was one hundred feet wide, with a bridge, and the large city of Opis near it. Here, at the frontier of Assyria and Media, the road from the eastern regions to Babylon joined the road northerly on which the Greeks were marching. An illegitimate brother of Artaxerxes was seen at the head of a numerous force, which he was conducting from Susa and Ekbatana as a reinforcement to the royal army. This great host halted to see the Greeks pass by; and Klearchus ordered the march in column of two abreast, employing himself actively to maintain an excellent array, and halting more than once. The army thus occupied so long a time in passing by the Persian host, that their numbers appeared greater than the reality, even to themselves; while the effect upon the Persian spectators was very imposing.[123] Here Assyria ended and Media began. They marched, still in a northerly direction, for six days through a portion of Media almost unpeopled, until they came to some flourishing villages which formed a portion of the domain of queen Parysatis; probably these villages, forming so marked an exception to the desert character of the remaining march, were situated on the Lesser Zab, which flows into the Tigris, and which Xenophon must have crossed, though he makes no mention of it. According to the order of march stipulated between the Greeks and Tissaphernes, the latter only provided a supply of provisions for the former to purchase; but on the present halt, he allowed the Greeks to plunder the villages, which were rich and full of all sorts of subsistence,—yet without carrying off the slaves. The wish of the satrap to put an insult on Cyrus, as his personal enemy,[124] through Parysatis, thus proved a sentence of ruin to these unhappy villagers. Five more days’ march, called twenty parasangs, brought them to the banks of the river Zabatus, or the Greater Zab, which flows into the Tigris near a town now called Senn. During the first of these five days, they saw on the opposite side of the Tigris a large town called Kænæ, from whence they received supplies of provisions, brought across by the inhabitants upon rafts supported by inflated skins.[125]

On the banks of the Great Zab they halted three days,—days of serious and tragical moment. Having been under feelings of mistrust, ever since the convention with Tissaphernes, they had followed throughout the whole march, with separate guides of their own, in the rear of his army, always maintaining their encampment apart. During their halt on the Zab, so many various manifestations occurred to aggravate the mistrust, that hostilities seemed on the point of breaking out between the two camps. To obviate this danger Klearchus demanded an interview with Tissaphernes, represented to him the threatening attitude of affairs, and insisted on the necessity of coming to a clear understanding. He impressed upon the satrap that, over and above the solemn oaths which had been interchanged, the Greeks on their side could have no conceivable motive to quarrel with him; that they had everything to hope from his friendship, and everything to fear, even to the loss of all chance of safe return, from his hostility; that Tissaphernes, also, could gain nothing by destroying them, but would find them, if he chose, the best and most faithful instruments for his own aggrandizement and for conquering the Mysians and the Pisidians,—as Cyrus had experienced while he was alive. Klearchus concluded his protest by requesting to be informed, what malicious reporter had been filling the mind of Tissaphernes with causeless suspicions against the Greeks.[126]

“Klearchus (replied the satrap), I rejoice to hear such excellent sense from your lips. You remark truly, that if you were to meditate evil against me, it would recoil upon yourselves. I shall prove to you, in my turn, that you have no cause to mistrust either the king or me. If we had wished to destroy you, nothing would be easier. We have superabundant forces for the purpose; there are wide plains in which you would be starved,—besides mountains and rivers which you would be unable to pass, without our help. Having thus the means of destroying you in our hands, and having nevertheless bound ourselves by solemn oaths to save you, we shall not be fools and knaves enough to attempt it now, when we should draw upon ourselves the just indignation of the gods. It is my peculiar affection for my neighbors, the Greeks,—and my wish to attach to my own person, by ties of gratitude, the Greek soldiers of Cyrus,—which have made me eager to conduct you to Ionia in safety. For I know that when you are in my service, though the king is the only man who can wear his tiara erect upon his head, I shall be able to wear mine erect upon my heart, in full pride and confidence.”[127]

So powerful was the impression made upon Klearchus by these assurances, that he exclaimed,—“Surely those informers deserve the severest punishment, who try to put us at enmity, when we are such good friends to each other, and have so much reason to be so.” “Yes (replied Tissaphernes), they deserve nothing less; and if you, with the other generals and lochages, will come into my tent to-morrow, I will tell you who the calumniators are.” “To-be-sure I will (rejoined Klearchus), and bring the other generals with me. I shall tell you at the same time, who are the parties that seek to prejudice us against you.” The conversation then ended, the satrap detaining Klearchus to dinner, and treating him in the most hospitable and confidential manner.
