The heralds rode away, but quickly returned, which proved that the King was near at hand. They brought with them guides, and said that in case the Hellenes were willing to agree to a truce, they were to conduct them to a place where food could be obtained. Clearchus and the other generals withdrew to consider this proposal, and they very quickly decided to conclude the truce at once. But nevertheless they again kept the heralds waiting for some time, so that it might appear as if it had been a good while before they could make up their minds to agree to the King’s proposals. [Illustration: THE GREAT KING FIGHTING WITH A MONSTER. _See page 3._] At last the decision was communicated to the heralds, and the two armies set out under the direction of the King’s guides, marching by a road which was one of the very worst that the Hellenes had ever seen. The district through which they were passing was part of the province of Babylonia, and was crossed in all directions by an infinite number of canals and ditches which kept the country well watered, and made it abundantly fruitful. At this time of year they were not usually full of water, but in order to make the march as difficult as possible for the Hellenes, the Persians had opened all the sluices. Consequently the canals could not be crossed except by bridges, of which there were none. The Barbarians had been anxious to give the Hellenes a practical example of the endless difficulties that they might expect to meet with in the course of their retreat. But if they hoped that this would have the effect of making them humble and ready to submit, they were much mistaken; Clearchus was not the man to be beaten by a difficulty of this sort, and under his direction the Hellenes set cheerily to work to make temporary bridges wherever they were required. In many places fallen trunks of date-palms lay ready to hand, and where these did not suffice, others were quickly felled. All soldiers under the age of thirty years were ordered to the work, in order that it might be carried through as fast as possible. Clearchus himself acted as overseer, moving about briskly among the soldiers with a staff in the right hand and a spear in the left, and whenever he saw a man loitering over his task, he did not hesitate to give him a beating. Although he was more than fifty years old, he laboured with his own hands with the utmost diligence, and this example was followed by many other of the older men.
