Such was the order and the composition of the two sides. The army of the Lacedaemonians appeared the larger;
but the number, either of the separate contingents or of the total on either side, I could not possibly state accurately. For on account of the secrecy of their polity the number of the Lacedaemonians was unknown; and that claimed for the others, on account of men's tendency to boast with regard to their own numbers, was discredited.
However, from the following mode of computation it is allowable to estimate the number of the Lacedaemonians that were then present. There were engaged in the battle seven battalions, without the Sciritae, who numbered six hundred, and in each battalion were four companies of fifty, in each company four platoons. In the first rank of each company fought four men; in depth, however, they were not all drawn up alike, but as each battalioncommander preferred—on the average eight deep. Along the whole line, then, exclusive of the Sciritae, the first rank consisted of four hundred and forty-eight men.[*](The sum-total of the whole army was 4,184 men (7×4×4×4=448×8=3,584+600=4,184).)
When they were on the point of engaging, exhortations were made to the several contingents by their own generals to the following effect: The Mantineans were reminded that the battle would be for fatherland, and, moreover, for dominion or servitude—that they should not be deprived of the one after having made trial of it, and should not again experience the other; the Argives, that the contest would be both for their ancient hegemony[*](Under Agamemnon.) and for their old equality of influence[*](Before the Persian Wars.) in the Peloponnese, that they must not brook being deprived of it forever, and at the same time must avenge themselves for many wrongs on men who were enemies and near neighbours at that; the Athenians, that it was glorious, contending along with many and brave allies, to be inferior to none, and that if they should conquer the Lacedaemonians in the Peloponnese they would have a greater empire and hold it more securely, and no one would ever invade their country again.
Such were the admonitions addressed to the Argives and their allies; the Lacedaemonians, however, exhorted one another man by man, using also their war-songs-as brave men to remember what they had learned, knowing that long-continued actual practice meant more for their salvation than any brief admonition, however well spoken.
After this the conflict commenced, the Argives and their allies advancing eagerly and impetuously, but the Lacedaemonians slowly and to the music of many flute-players placed among them according to custom, not with any religious motive, but in order that they might march up with even step and keeping time without breaking their order, as large armies are apt to do in going into battle.
