Note 651 — Chapter XXXVI · FROM THE IONIC REVOLT TO THE BATTLE OF MARATHON.
Reading edition
Herodot. vi, 112. Πρῶτοι μὲν γὰρ Ἑλλήνων πάντων τῶν ἡμεῖς ἴδμεν, δρόμῳ ἐς πολεμίους ἐχρήσαντο.
The running pace of the charge was obviously one of the most remarkable events connected with the battle. Colonel Leake and Mr. Finlay seem disposed to reduce the run to a quick march; partly on the ground that the troops must have been disordered and out of breath by running a mile. The probability is, that they really were so, and that such was the great reason of the defeat of the centre. It is very probable that a part of the mile run over consisted of declivity. I accept the account of Herodotus literally, though whether the distance be exactly stated, we cannot certainly say: indeed the fact is, that it required some steadiness of discipline to prevent the step of hoplites, when charging, from becoming accelerated into a run. See the narrative of the battle of Kunaxa in Xenoph. Anabas. i, 8, 18; Diodor. xiv, 23: compare Polyæn. ii, 2, 3. The passage of Diodorus here referred to contrasts the advantages with the disadvantages of the running charge.
Both Colonel Leake and Mr. Finlay try to point out the exact ground occupied by the two armies: they differ in the spot chosen, and I cannot think that there is sufficient evidence to be had in favor of any spot. Leake thinks that the Persian commanders were encamped in the plain of Tricorythos, separated from that of Marathon by the great marsh, and communicating with it only by means of a causeway (Leake, Transact. ii, p. 170).
