History of the Peloponnesian War. Thucydides
the attack had been made in time of peace, and was perfectly unexpected, there were of course men and stock in the fields; and the Thebans wished if possible to have some prisoners to exchange against their countrymen in the town, should any chance to have been taken alive. Such was their plan. But the Platæans suspected their intention almost before it was formed, and becoming alarmed for their fellow-citizens outside the town, sent a herald to the Thebans, reproaching them for their unscrupulous attempt to seize their city in time of peace, and warning them against any outrage on those outside. Should the warning be disregarded, they threatened to put to death the men they had in their hands, but added that, on the Thebans retiring from their territory, they would surrender the prisoners to their friends. This is the Theban account of the matter, and they say that they had an oath given them. The Platæans, on the other hand, do not admit any promise of an immediate surrender, but make it contingent upon subsequent negotiation: the oath they deny altogether. Be this as it may, upon the Thebans retiring from their territory without committing any injury, the Platæans hastily got in whatever they had in the country and immediately put the men to death. The prisoners were a hundred and eighty in number; Eurymachus, the person with whom the traitors had negotiated, being one.
This done, the Platæans sent a messenger to Athens, gave back the dead to the Thebans under a truce, and arranged things in the city as seemed best to meet the present emergency. The Athenians meanwhile, having had word of the affair sent them immediately after its occurrence, had instantly seized all the Bœotians in Attica, and sent a herald to the Platæans to forbid their proceeding to extremities with their Theban prisoners without instructions from Athens. The news of the men’s death had of course not arrived; the first messenger having left Platæa just when the Thebans entered it, the second just after their defeat and capture; so there was no later news. Thus the Athenians sent their orders in ignorance of the facts; and the herald on his arrival found the men slain. After this the Athenians marched to Platæa and brought in provisions, and left a garrison in the place, also taking away the women and children and such of the men as were least efficient.
After the affair at Platæa the treaty had been broken by an overt act, and Athens at once prepared for war, as did also Lacedæmon and her allies. They resolved to send embassies to the king and to such other of the barbarian powers as either party could look to for assistance, and tried to ally themselves with the independent states at home. Lacedæmon, in addition to the existing marine, gave orders to the states that had declared for her in Italy and Sicily to build vessels up to a grand total of five hundred, the quota of each city being determined by its size, and also to provide a specified sum of money. Till these were ready they were to remain neutral and to admit single Athenian ships into their harbours. Athens on her part reviewed her existing confederacy, and sent embassies to the places more immediately round Peloponnese, Corcyra, Cephallenia, Acarnania, and Zacynthus; perceiving that if these could be relied on she could carry the war all round Peloponnese.
And if both sides nourished the boldest hopes and put forth their utmost strength for the war, this was only natural. Zeal is always at its height at the commencement of an undertaking; and on this particular occasion Peloponnese and Athens were both full of young men whose inexperience made them eager to take up arms, while the rest of Hellas stood straining with excitement at the conflict of its leading cities. Everywhere predictions were being recited and oracles being chanted by such persons as collect them, and this not only in the contending cities. Further, some while before this, there was an earthquake at Delos, for the first time in the memory of the Hellenes. This was said and thought to be ominous of the events impending; indeed, nothing of the kind that happened was allowed to pass without remark. The good wishes of men made greatly for the Lacedæmonians, especially as they proclaimed themselves the liberators of Hellas. No private or public effort that could help them in speech or action was omitted; each thinking that the cause suffered wherever he could not himself see to it. So general was the indignation felt against Athens, whether by those who wished to escape from her empire, or were apprehensive of being absorbed by it. Such were the preparations and such the feelings with which the contest opened.
The allies of the two belligerents were the following. These were the allies of Lacedæmon: all the Peloponnesians within the Isthmus except the Argives and Achæans, who were neutral; Pellene being the only Achæan city that first joined in the war, though her example was afterwards followed by the rest. Outside Peloponnese the Megarians, Locrians, Bœotians, Phocians, Ambraciots, Leucadians, and Anactorians. Of these, ships were furnished by the Corinthians, Megarians, Sicyonians, Pellenians, Eleans, Ambraciots, and Leucadians; and cavalry by the Bœotians, Phocians, and Locrians. The other states sent infantry. This was the Lacedæmonian confederacy. That of Athens comprised the Chians, Lesbians, Platæans, the Messenians in Naupactus, most of the Acarnanians, the Corcyræans, Zacynthians, and some tributary cities in the following countries, viz., Caria upon the sea with her Dorian neighbours, Ionia, the Hellespont, the Thracian towns, the islands lying between Peloponnese and Crete towards the east, and all the Cyclades except Melos and Thera. Of these, ships were furnished by Chios, Lesbos, and Corcyra, infantry and money by the rest. Such were the allies of either party and their resources for the war.
Immediately after the affair at Platæa, Lacedæmon sent round orders to the cities in Peloponnese and the rest of her confederacy to prepare troops and the provisions requisite for a foreign campaign, in order to invade Attica. The several states were ready at the time appointed and assembled at the Isthmus, the contingent of each city being two-thirds of its whole force. After the whole army had mustered, the Lacedæmonian king, Archidamus, the leader of the expedition, called together the generals of all the states and the principal persons and officers, and exhorted them as follows: —
Teloponnesians and allies, our fathers made many campaigns both within and without Peloponnese, and the elder men among us here are not without experience in war. Yet we have never set out with a larger force than the present; and if our numbers and efficiency are remarkable, so also is the power of the state against which we march. We ought not then to show ourselves inferior to our ancestors, or unequal to our own reputation. For the hopes and attention of all Hellas are bent upon the present effort, and its sympathy is with the enemy of the hated Athens. Therefore, numerous as the invading army may appear to be, and certain as some may think it that our adversary will not meet us in the field, this is no sort of justification for the least negligence upon the march; but the officers and men of each particular city should always be prepared for the advent of danger in their own quarters. The course of war cannot be foreseen, and its attacks are generally dictated by the impulse of the moment; and where overweening self-confidence has despised preparation, a wise apprehension has often been able to make head against superior numbers. Not that confidence is out of place in an army of invasion, but in an enemy’s country it should also be accompanied by the precautions of apprehension: troops will by this combination be best inspired for dealing a blow, and best secured against receiving one. In the present instance, the city against which we are going, far from being so impotent for defence, is on the contrary most excellently equipped at all points; so that we have every reason to expect that they will take the field against us, and that if they have not set out already before we are there, they will certainly do so when they see us in their territory wasting and destroying their property. For men are always exasperated at suffering injuries to which they are not accustomed, and on seeing them inflicted before their very eyes; and where least inclined for reflexion, rush with the greatest heat to action. The Athenians are the very people of all others to do this, as they aspire to rule the rest of the world, and are more in the habit of invading and ravaging their neighbours’ territory, than of seeing their own treated in the like fashion. Considering, therefore, the power of the state against which we are marching, and the greatness of the reputation which, according to the event, we shall win or lose for our ancestors and ourselves, remember as you follow where you may be led to regard discipline and vigilance as of the first importance, and to obey with alacrity the orders transmitted to you; as nothing contributes so much to the credit and safety of an army as the union of large bodies by a single discipline.’
With this brief speech dismissing the assembly, Archidamus first sent off Melesippus, son of Diacritus, a Spartan, to Athens, in case she should be more inclined to submit on seeing the Peloponnesians actually on the march. But the Athenians did not admit into the city or to their assembly; Pericles having already carried a motion
