Both sides eagerly drew
together for the decisive conflict,
1 their armies in battle formation, while the soothsayers,
having sacrificed on both sides, declared that victory was foreshadowed by the gods.

In the disposition of forces the Mantineians with the rest of the
Arcadians occupied the right wing with the Lacedaemonians as their neighbours and supporters,
and next to these were Eleians and Achaeans; and the weaker of the remaining forces occupied
the centre, while the Athenians filled the left wing. The Thebans themselves had their post on
the left wing, supported by the Arcadians, while they entrusted the right to the Argives. The
remaining multitude filled the middle of the line: Euboeans, Locrians, Sicyonians, Messenians,
Malians, Aenianians, together with Thessalians and the remaining allies. Both sides divided the
cavalry and placed contingents on each wing.

Such was the
array of the armaments, and now as they approached one another, the trumpets sounded the battle
charge, the armies raised the battle shout, and by the very volume of their cries betokened
their victory. At first they engaged in a cavalry battle on the flanks in which they outbid
each other in keen rivalry.
[

Now as the Athenian horse attacked
the Theban they suffered defeat not so much because of the quality of their mounts nor yet on
the score of the riders' courage or experience in horsemanship, for in none of these
departments was the Athenian cavalry deficient; but it was in the numbers and equipment of the
light-armed troops and in their tactical skill that they were far inferior to their opponents.
Indeed they had only a few javelin-throwers, whereas the Thebans had three times as many
slingers and javelin-throwers sent them from the regions about Thessaly.
[

These people practised from boyhood assiduously this type of fighting
and consequently were wont to exercise great weight in battles because of their experience in
handling these missiles. Consequently the Athenians, who were continually being wounded by the
light-armed and were harried to exhaustion by the opponents who confronted them, all turned and
fled.
[

But having fled beyond the flanks, they managed to
retrieve their defeat, for even in their retreat they did not break their own phalanx, and
encountering simultaneously the Euboeans and certain mercenaries who had been dispatched to
seize the heights near by, they gave battle and slew them all.
[

Now the Theban horse did not follow up the fugitives, but, assailing the phalanx opposing
them, strove zealously to outflank the infantry. The battle was a hot one; the Athenians were
exhausted and had turned to flee, when the Eleian cavalry-commander, assigned to the rear, came
to the aid of the fugitives and, by striking down many Boeotians, reversed the course of the
battle.
[

So while the Eleian cavalry by their appearance in
this fashion on the left wing retrieved the defeat their allies had sustained, on the other
flank both cavalry forces lashed at one another and the battle hung for a short time in the
balance, but then, because of the number and valour of the Boeotian and Thessalian horsemen,
the contingents on the Mantineian side were forced back, and with considerable loss took refuge
with their own phalanx.
