Arrived at the Ister, Darius, a commander of great and manifold experience, is represented as having ordered the Ionian Greeks to break down the bridge over the river after he had passed it, and to follow him into the unknown north. No reason is either given or is conceivable for such a suicidal plan. The ships, moreover, are to remain in the Ister. He was dissuaded from this by the advice of Koës, the Greek tyrant of Mytilene. He then gave orders that the Greeks should remain at the river sixty days, and if he did not return in that time, should loose the bridge and sail away.
No advantage can possibly be gained by treating this as serious history. It is inconceivable that any general of experience should either propose to deliberately cut his own line of communications when about to enter an unknown region, or even that he should have appointed a set limit of time, and that not very long, after which it might be cut.
The story is in all probability merely a peg whereon to hang an indictment of the Greek tyrants of the Asian coast, and is designed for the glorification of the part played by Miltiades in the subsequent debate on the advisability of leaving Darius to his fate.
The truth it contains may amount to no more than that the fleet did not go farther than the Ister, and that Darius did not intend to remain north of the river for any length of time.
The tale of the actual campaigning in Scythia is more extraordinary still. The Persians are represented as having penetrated beyond the river Tanais (Don) to the Oarus, (probably the Volga), on which they built a series of forts. They then returned to the Ister by a circuitous route, and, as might indeed be expected, the sixty days had elapsed before their arrival. Such is Herodotus’ story.
Strabo vii. 305.
A reference to this campaign in the works of the geographer Strabo shows that Herodotus’ version of its history was not the only one current among the Greeks. He says that the king and his army, when between the Ister and the Tyras (Dniester), were compelled to turn back under stress of thirst.
Ktesias, a Greek who spent a large part of his life at the Persian Court, and who, though unreliable, is not likely to understate Persian exploits, Ktes. Pers. 17. says that the king only penetrated fifteen days’ march beyond the Ister.
CREDIBILITY OF THE NARRATIVE.
The impossibilities of Herodotus’ story are so manifest that it is hardly necessary to point them out. How could the commissariat of a large force have been provided for on a march of that length through a hostile country where the natives, according to the historian’s own account, destroyed all local food supplies in advance of the army? How could the army and the transport required for it have been carried across such rivers as would have to be passed ere the Volga was reached,—the Sereth, the Pruth, the Dniester, Dnieper, Boug, and Don, not to mention numerous minor unfordable streams? If this long march was undertaken, why did not Darius employ the fleet for commissariat purposes, as was the custom in Persian campaigns of this age, where the fleet could possibly be employed?
