Such being the structure of the wall by which the Plataeans were blockaded, when their preparations were completed, they waited for a stormy night of wind and rain and without any moon, and then set out, guided by the authors of the enterprise. Crossing first the ditch that ran round the town, they next gained the wall of the enemy unperceived by the sentinels, who did not see them in the darkness, or hear them, as the wind drowned with its roar the noise of their approach; besides which they kept a good way off from each other, that they might not be betrayed by the clash of their weapons. They were also lightly equipped, and had only the left foot shod to preserve them from slipping in the mire. They came up to the battlements at one of the intermediate spaces where they knew them to be unguarded: those who carried the ladders went first and planted them; next twelve light-armed soldiers with only a dagger and a breastplate mounted, led by Ammias, son of Coroebus, who was the first on the wall; his followers getting up after him and going six to each of the towers. After these came another party of light troops armed with spears, whose shields, that they might advance the easier, were carried by men behind, who were to hand them to them when they found themselves in presence of the enemy. After a good many had mounted they were discovered by the sentinels in the towers, by the noise made by a tile which was knocked down by one of the Plataeans as he was laying hold of the battlements. The alarm was instantly given, and the troops rushed to the wall, not knowing the nature of the danger, owing to the dark night and stormy weather; the Plataeans in the town having also chosen that moment to make a sortie against the wall of the Peloponnesians upon the side opposite to that on which their men were getting over, in order to divert the attention of the besiegers. Accordingly they remained distracted at their several posts, without any venturing to stir to give help from his own station, and at a loss to guess what was going on. Meanwhile the three hundred set aside for service on emergencies went outside the wall in the direction of the alarm. Fire-signals of an attack were also raised towards Thebes; but the Plataeans in the town at once displayed a number of others, prepared beforehand for this very purpose, in order to render the enemy’s signals unintelligible, and to prevent his friends getting a true idea of what was passing and coming to his aid before their comrades who had gone out should have made good their escape and be in safety.
Meanwhile the first of the scaling party that had got up, after carrying both the towers and putting the sentinels to the sword, posted themselves inside to prevent any one coming through against them; and rearing ladders from the wall, sent several men up on the towers, and from their summit and base kept in check all of the enemy that came up, with their missiles, while their main body planted a number of ladders against the wall, and knocking down the battlements, passed over between the towers; each as soon as he had got over taking up his station at the edge of the ditch, and plying from thence with arrows and darts any who came along the wall to stop the passage of his comrades. When all were over, the party on the towers came down, the last of them not without difficulty, and proceeded to the ditch, just as the three hundred came up carrying torches. The Plataeans, standing on the edge of the ditch in the dark, had a good view of their opponents, and discharged their arrows and darts upon the unarmed parts of their bodies, while they themselves could not be so well seen in the obscurity for the torches; and thus even the last of them got over the ditch, though not without effort and difficulty; as ice had formed in it, not strong enough to walk upon, but of that watery kind which generally comes with a wind more east than north, and the snow which this wind had caused to fall during the night had made the water in the ditch rise, so that they could scarcely breast it as they crossed. However, it was mainly the violence of the storm that enabled them to effect their escape at all.
Starting from the ditch, the Plataeans went all together along the road leading to Thebes, keeping the chapel of the hero Androcrates upon their right; considering that the last road which the Peloponnesians would suspect them of having taken would be that towards their enemies’ country. Indeed they could see them pursuing with torches upon the Athens road towards Cithaeron and Druoskephalai or Oakheads. After going for rather more than half a mile upon the road to Thebes, the Plataeans turned off and took that leading to the mountain, to Erythrae and Hysiae, and reaching the hills, made good their escape to Athens, two hundred and twelve men in all; some of their number having turned back into the town before getting over the wall, and one archer having been taken prisoner at the outer ditch. Meanwhile the Peloponnesians gave up the pursuit and returned to their posts; and the Plataeans in the town, knowing nothing of what had passed, and informed by those who had turned back that not a man had escaped, sent out a herald as soon as it was day to make a truce for the recovery of the dead bodies, and then, learning the truth, desisted. In this way the Plataean party got over and were saved.
Towards the close of the same winter, Salaethus, a Lacedaemonian, was sent out in a galley from Lacedaemon to Mitylene. Going by sea to Pyrrha, and from thence overland, he passed along the bed of a torrent, where the line of circumvallation was passable, and thus entering unperceived into Mitylene told the magistrates that Attica would certainly be invaded, and the forty ships destined to relieve them arrive, and that he had been sent on to announce this and to superintend matters generally. The Mitylenians upon this took courage, and laid aside the idea of treating with the Athenians; and now this winter ended, and with it ended the fourth year of the war of which Thucydides was the historian.
The next summer the Peloponnesians sent off the forty-two ships for Mitylene, under Alcidas, their high admiral, and themselves and their allies invaded Attica, their object being to distract the Athenians by a double movement, and thus to make it less easy for them to act against the fleet sailing to Mitylene. The commander in this invasion was Cleomenes, in the place of King Pausanias, son of Pleistoanax, his nephew, who was still a minor. Not content with laying waste whatever had shot up in the parts which they had before devastated, the invaders now extended their ravages to lands passed over in their previous incursions; so that this invasion was more severely felt by the Athenians than any except the second; the enemy staying on and on until they had overrun most of the country, in the expectation of hearing from Lesbos of something having been achieved by their fleet, which they thought must now have got over. However, as they did not obtain any of the results expected, and their provisions began to run short, they retreated and dispersed to their different cities.
In the meantime the Mitylenians, finding their provisions failing, while the fleet from Peloponnese was loitering on the way instead of appearing at Mitylene, were compelled to come to terms with the Athenians in the following manner. Salaethus having himself ceased to expect the fleet to arrive, now armed the commons with heavy armour, which they had not before possessed, with the intention of making a sortie against the Athenians. The commons, however, no sooner found themselves possessed of arms than they refused any longer to obey their officers; and forming in knots together, told the authorities to bring out in public the provisions and divide them amongst them all, or they would themselves come to terms with the Athenians and deliver up the city.
The government, aware of their inability to prevent this, and of the danger they would be in, if left out of the capitulation, publicly agreed with Paches and the army to surrender Mitylene at discretion and to admit the troops into the town; upon the understanding that the Mitylenians should be allowed to send an embassy to Athens to plead their cause, and that Paches should not imprison, make slaves of, or put to death any of the citizens until its return. Such were the terms of the capitulation; in spite of which the chief authors of the negotiation with Lacedaemon were so completely overcome by terror when the army entered that they went and seated themselves by the altars, from which they were raised up by Paches under promise that he would do them no wrong, and lodged by him in Tenedos, until he should learn the pleasure of the Athenians concerning them. Paches also sent some galleys and seized Antissa, and took such other military measures as he thought advisable.
Meanwhile the Peloponnesians in the forty ships, who ought to have made all haste to relieve Mitylene, lost time in coming round Peloponnese itself, and proceeding leisurely on the remainder of the voyage, made Delos without having been seen by the Athenians at Athens, and from thence arriving at Icarus and Myconus, there first heard of the fall of Mitylene. Wishing to know the truth, they put into Embatum, in the Erythraeid, about seven days after the capture of the town. Here they learned the truth, and began to consider what they were to do; and Teutiaplus, an Elean, addressed them as follows:
“Alcidas and Peloponnesians who share with me the command of this armament, my advice is to sail just as we are to Mitylene, before we have been heard of. We may expect to find the Athenians as much off their guard as men generally are who have just taken a city: this will certainly be so by sea, where they have no idea of any enemy attacking them, and where our strength, as it happens, mainly lies; while even their land forces are probably scattered about the houses in the carelessness of victory. If therefore we were to fall upon them suddenly and in the night, I have hopes, with the help of the well-wishers that we may have left inside the town, that we shall become masters of the place. Let us not shrink from the risk, but let us remember that this is just the occasion for one of the baseless panics common in war: and that to be able to guard against these in one’s own case, and to detect the moment when an attack will find an enemy at this disadvantage, is what makes a successful general.”
These words of Teutiaplus failing to move Alcidas, some of the Ionian exiles and the Lesbians with the expedition began to urge him, since this seemed too dangerous, to seize one of the Ionian cities or the Aeolic town of Cyme, to use as a base for effecting the revolt of Ionia. This was by no means a hopeless enterprise, as their coming was welcome everywhere; their object would be by this move to deprive Athens of her chief source of revenue, and at the same time to saddle her with expense, if she chose to blockade them; and they would probably induce Pissuthnes to join them in the war. However, Alcidas gave this proposal as bad a reception as the other, being eager, since he had come too late for Mitylene, to find himself back in Peloponnese as soon as possible.
