The Argives thought themselves bound to abide by the conditions of the
truce, though made without their consent; but shortly after the retreat
of Agis, an Athenian force of a thousand hoplites and three hundred
cavalry arrived at Argos, and Alcibiades, who was present in the
character of ambassador, strongly urged the renewal of the campaign.
His proposal was warmly supported by the Mantineans and Eleans, and
they and the Athenians marched forthwith against Orchomenus in Arcadia,
which was in alliance with Sparta; and the Argives, who had wavered at
first, soon afterwards joined them. Orchomenus was gained over with
little trouble, and then the Eleans were eager to proceed against
Lepreum, a town in their alliance which had gone over to Sparta. But
the Argives, Athenians, and Mantineans, insisted on attacking Tegea,
where there was a party opposed to Sparta, by whose means they hoped to
bring this powerful city, the ancient rival of Mantinea, to their side.
Thereupon the Eleans abandoned the expedition, and went home in a rage,
but the rest of the allies took up their quarters at Mantinea, and
prepared to make an attack on Tegea.
The Spartans were in high anger against Agis for his unsoldier-like
conduct in the recent campaign, and when they heard of the capitulation
of Orchomenus their resentment rose to such a pitch that it was
proposed to inflict on him a heavy fine, and raze his house to the
ground. At his earnest entreaty they consented to reserve the sentence,
and give him an opportunity of wiping out the stain on his honour; but
as a mark of diminished confidence they appointed ten commissioners,
without whose consent he was not allowed to lead an army out of the
city.
They had just come to this decision when an urgent message arrived from
Tegea, bidding them to bring help with all speed, or the town would be
lost. The imminent peril startled the Spartans from their wonted
apathy, and they set out at once in full force to the relief of Tegea.
On reaching the borders of Arcadia they sent back the elder and younger
men, amounting to a sixth part of the army, to serve as a garrison in
Sparta; and at the same time couriers were despatched to summon their
allies in Arcadia and central Greece. The Arcadians arrived in time to
take part in the battle, but the Boeotians, Corinthians, and others,
though they hastened to obey the order, were delayed by a long and
difficult march, through the hostile territory of Argos.
Passing by Tegea, Agis entered the district of Mantinea, and having
pitched his camp began to lay waste the country. Informed of his
approach, the Argives and their allies marched out to meet him, and
choosing a position on the slope of a hill, defended in front by rugged
and broken ground, they drew up in order of battle. The Spartans,
incited, doubtless, by the example of their king, who was eager to
redeem his reputation, rushed impetuously to the assault; and they were
already within a stone's-throw of the enemy when a Spartan veteran
cried out to Agis: "Heal not ill with ill!" His meaning was that in
Argos Agis had been too cold, and now he was too hot. Agis heard the
warning voice, and his own good sense must have shown him how rashly he
was acting; accordingly, at the very moment of encounter, he gave the
word to retreat, and fell back to the neighbourhood of Tegea. At this
place there was a copious head of water, which, when properly
regulated, served to irrigate the fields of Tegea and Mantinea. The
disposal of the water-supply was a constant source of dispute between
the two rival cities; and Agis now prepared to turn the whole volume of
the fountain towards Mantinea, expecting that the Mantineans, when they
saw their fields threatened with inundation, would come down into the
plain to hinder the mischief.
The Argives and their allies were dumb-foundered by the sudden
disappearance of the Spartans; and when they had recovered from their
astonishment, they waited impatiently for the order to pursue the
runaways. As no such order was given, cries of "Treason!" arose in the
ranks, and the generals were openly accused of having sold themselves
to the enemy. The Spartans, it was asserted, had been allowed to
escape, when they were fairly caught under the walls of Argos; and now
the confederates had been betrayed a second time by their officers.
Amid the general clamour the Argive commanders stood for a moment
confounded and amazed; then recovering themselves they gave the word to
advance, and led their forces down into the plain. Here they passed the
night in the open field, and early next morning they stood to their
arms, and prepared for an immediate attack.
Agis was not aware that the Argive generals had taken up a new
position, and thinking that the confederates were still stationed on
the hill, he gave up his scheme of diverting the water, and directed
his march towards the place where he had first encamped. As they
proceeded thus in marching order, and quite unprepared for any hostile
movement, the Spartans suddenly found themselves face to face with the
whole Argive army, drawn up in order of battle. For one instant it
seemed as if a panic were about to spread through the Spartan ranks;
then their wonderful discipline prevailed, and with all promptitude,
but without flurry or confusion, the necessary orders were passed from
the King to the commanders of divisions, from these again to the
colonels, from the colonels to the captains, and from the captains down
to the sergeants, [Footnote: I have thought it best to give the English
titles, which of course have only a general correspondence with the
Greek Polemarch, Lochagus, etc.] who in their turn had to see that the
required movement was executed by the men under their command: for such
was the regular gradation of authority and responsibility in the
Spartan army. Thanks to this perfect organization, in a very few
minutes every man was in his place and ready for battle.
On the left wing of the Spartan army were posted the Sciritae, hardy
mountaineers from southern Arcadia; next to them stood the enfranchised
Helots, who had served under Brasidas in Thrace, and others of the same
race who had received the Spartan citizenship in reward for public
service; then came the main body of the Spartans themselves, and after
them the rest of the Arcadian allies; while the right wing was assigned
by immemorial privilege to the Tegeans, with whom were a few picked
Spartans. The cavalry, never a very strong part of the Spartan army,
were posted on either flank.
On the other side the Mantineans held the place of honour on the right
wing, because the engagement was fought in their territory; next in
order were the Arcadian allies of Argos, and after them, more towards
the centre, stood a picked troop of a thousand Argives, trained and
equipped at the public expense; then followed the main body of the
Argive troops, with the rest of their allies, the Athenians occupying
the extreme left. As to the numbers engaged, nothing certain is known.
Some time was lost by the Argive army in delivering the customary
harangues addressed by the generals of the several contingents to their
men, and this enabled the Spartans to steady their ranks before the
fighting began. They, on their side, men of war from their youth, had
no need of set speeches to remind them of their duty; but pithy words
of exhortation passed from man to man, and high and clear rose their
national war-songs, thrilling them with the memories of their heroic
past. Then the signal was given on both sides to charge, and the
Argives and their allies rushed impetuously to the onset, while the
Spartans advanced to meet them with even and deliberate pace, timed to
the music of numerous pipers, who were stationed at regular intervals
in their ranks.
The regular equipment of the Greek infantry soldier consisted, besides
his helmet and body-armour, of shield and lance, and in advancing to
battle he had always a tendency to diverge towards the right, from a
natural wish to keep his shielded side towards the enemy. This
divergence from the forward direction was begun by the man posted on
the extreme right; his comrade on the left followed his example, and
the deflection was continued along the whole line. The consequence was
that when two armies came into action, the left wing on either side was
greatly outflanked by the opponents' right; and the battle of Mantinea
affords no exception to this rule, for not even Spartan discipline was
able to counteract the overpowering instinct of self-preservation.
Seeing that his left wing was on the point of being outflanked by the
Mantineans, Agis signalled to the Sciritae and Brasideans to draw off
in a lateral direction towards the left, in order to present an equal
line to the right wing of the enemy. The order was executed, and to
fill up the gap thus produced on the left of his own centre, Agis
ordered the Spartan officers commanding on his right wing to bring up
their men and occupy the vacant space. They, however, flatly refused to
obey the order, and consequently the Sciritae and Brasideans were
assailed in front and on both flanks by overwhelming numbers, and
driven back with great loss to their camp.
So completely were the Spartans out-manoeuvred and worsted in tactics,
through the blunders of their general, and the cowardice of his
subordinates. But in this terrible crisis they showed what native
valour, aided by life-long discipline, can do. Leaving a victorious
enemy in their rear, they advanced without flinching against the
opposing centre, where the main body of the Argives were posted, with
the troops of Orneae and Cleonaea supporting them on the left. Then it
was seen that neither the courage of the Spartans, nor the terror of
their name, had diminished with the lapse of time; for when the
confederate troops found themselves face to face with the renowned
warrior of the Eurotas, they turned and fled, almost without striking a
blow, and trampling their comrades under foot, in their haste to avoid
the thrust of the Spartan lances. The Athenians on the left wing were
now in great danger; for the charge of the troops of Agis had cut them
off from the centre, and they were attacked on the other flank by the
Tegeans and Spartans. They were saved from immediate destruction by the
exertions of their own cavalry, and presently found themselves at
liberty to retire from the field; for Agis, having completed the rout
of the main body, called off his men, and went to the relief of his own
left. The Mantineans and the Argive Thousand made no effort to retrieve
the fortunes of the day, but gave way before the first onset of the
Spartans, and joined the flight of their comrades. The Mantineans
suffered severely in their retreat, but of the Argives only a few were
slain.
Such was the battle of Mantinea, which completely restored the military
fame of the Spartans, and blotted out the reproach of cowardice and
sloth which for some years past had rested on their name.
