do: we must detach from the enemy all the fortresses we can and secure all we can for our own: if this is done, the larger supply will be in the hands of those who can stow away the larger store, and the weaker will suffer siege. [16] At present we are like mariners on the ocean: they may sail on for ever, but the seas they have crossed are no more theirs than those that are still unsailed. But if we hold the fortresses, the enemy will find they are living in a hostile land, while we have halcyon weather. [17] Some of you may dread the thought of garrison duty far from home; if so, dispel your doubts. We Persians, who must, as it is, be exiles for the time, will undertake the positions that are nearest to the foe, while it will be for you to occupy the land on the marches between Assyria and yourselves and put it under tillage. [18] For, if we can hold his inner line, your peace will not be disturbed in the outlying parts: he will scarcely neglect the danger at his door to attack you out in the distance." [19] At this the whole assembly rose to express their eagerness and assent, and Cyaxares stood up with them. And both Gadatas and Gobryas offered to fortify a post if the allies wished, and thus provide two cities of refuge to start with. [20] Finally Cyrus, thus assured of the general consent to his proposals, said, "If we really wish to carry out what we have set ourselves, we must prepare battering-rams and siege engines, and get together mechanics and builders for our own castles." [21] Thereupon Cyaxares at once undertook to provide an engine at his own expense, Gadatas and Gobryas made themselves responsible for a second, Tigranes for a third, and Cyrus himself promised he would try to furnish two. [22] That done, every one set to work to find engineers and artisans and to collect material for the machines; and superintendents were appointed from those best qualified for the work. [23] Now Cyrus was aware that all this would take some time, and therefore he encamped his troops in the healthiest spot he could find and the easiest to supply, strengthening, wherever necessary, the natural defences of the place, so that the detachment left in charge for the time should always be in complete security, even though he might be absent himself with the main body of his force. [24] Nor was this all; he questioned those who knew the country best, and, learning where he would be rewarded for his pains, he would lead his men out to forage, and thus procure as large supplies as possible, keep his soldiers in the best of health and strength, and fix their drill in their minds.
