Cyropaedia

And when, as he proceeded, he came in sight of the city of Babylon and it seemed to him that the road which he was following led close by the walls, he called Gobryas and Gadatas to him and asked if there were not another road, so that they need not march right by the wall.

Yes, sire, answered Gobryas; in fact, there are many roads; but I supposed that you would surely wish to march as near to the city as possible, in order to show him that your army is now large and imposing; for even when you had a smaller force, you came right up to the very walls and he saw that we had no great numbers. So now, even if he really is to some extent prepared (for he sent word to you that he was making preparations to fight you), I am sure that, when he sees your forces, his own will again seem to him extremely ill-prepared.

You seem to be surprised, Gobryas, said[*](Cyrus’s tactics in passing Babylon) Cyrus in answer, that I marched right up to the walls when I came with a much smaller army, whereas now with a larger force I am unwilling to march close up under the walls.

But do not be surprised; for marching up to and marching by are not the same thing. For every one leads up in the order best for fighting and the wise also retreat in the safest possible way, and not in the quickest,

but an army must needs march by with the wagons in an extended line and with the rest of the baggage vans in a long train. And these must all be covered by soldiers, and the enemy must never see the baggage wagons unprotected by arms.

When people march in this way, therefore, they necessarily have the fighting men drawn out in a thin, weak line. If, then, the enemy should ever decide to sally out in a compact body from their walls, on whichever part they came to close quarters they would close with much greater force than those have who are marching by.

Then, too, those who are marching in a long column must be a long distance from their supports, while the townspeople have but a short way to go to make a dash on a force near them and again retire.

On the other hand, if we march by at a distance from the walls not less than that at which we are now proceeding with our long extended line, they will have a view of our full numbers, to be sure, but behind the fringe of arms the whole host will look terrible.

Be that as it may, if they should really make a sally at any point, we should see them a long way off and not be caught unprepared; or rather, I should say, friends, they will not so much as make the attempt when they have to go far from their walls, unless they judge that the whole of their force is superior to the whole of ours; for a retreat is a perilous thing for them.

When he said this, those present agreed that what he said was right, and Gobryas led the way as he had directed. And as the army marched by the city, he constantly kept the part just passing the city the strongest, and so moved on.

Thus he continued his march and came in the[*](Cyrus captures three forts) usual number of days to the place on the boundaries between Media and Syria from which he had originally started. Of the three forts of the Syrians there, Cyrus in person assaulted one, the weakest, and took it by storm; of the other two, Cyrus, by intimidation, brought the garrison of the one to surrender, and Gadatas, by persuasion, that of the other.
