The same summer and simultaneously with the expedition against Plataea, the Athenians marched with two thousand heavy infantry and two hundred horse against the Chalcidians in the direction of Thrace and the Bottiaeans, just as the corn was getting ripe, under the command of Xenophon, son of Euripides, with two colleagues. Arriving before Spartolus in Bottiaea, they destroyed the corn and had some hopes of the city coming over through the intrigues of a faction within. But those of a different way of thinking had sent to Olynthus; and a garrison of heavy infantry and other troops arrived accordingly. These issuing from Spartolus were engaged by the Athenians in front of the town: the Chalcidian heavy infantry, and some auxiliaries with them, were beaten and retreated into Spartolus; but the Chalcidian horse and light troops defeated the horse and light troops of the Athenians. The Chalcidians had already a few targeteers from Crusis, and presently after the battle were joined by some others from Olynthus; upon seeing whom the light troops from Spartolus, emboldened by this accession and by their previous success, with the help of the Chalcidian horse and the reinforcement just arrived again attacked the Athenians, who retired upon the two divisions which they had left with their baggage. Whenever the Athenians advanced, their adversary gave way, pressing them with missiles the instant they began to retire. The Chalcidian horse also, riding up and charging them just as they pleased, at last caused a panic amongst them and routed and pursued them to a great distance. The Athenians took refuge in Potidæa, and afterwards recovered their dead under truce, and returned to Athens with the remnant of their army; four hundred and thirty men and all the generals having fallen. The Chalcidians and Bottiaeans set up a trophy, took up their dead, and dispersed to their several cities.

The same summer, not long after this, the Ambraciots and Chaonians, being desirous of reducing the whole of Acarnania and detaching it from Athens, persuaded the Lacedaemonians to equip a fleet from their confederacy and send a thousand heavy infantry to Acarnania, representing that, if a combined movement were made by land and sea, the coast Acarnanians would be unable to march, and the conquest of Zacynthus and Cephallenia easily following on the possession of Acarnania, the cruise round Peloponnese would be no longer so convenient for the Athenians. Besides which there was a hope of taking Naupactus. The Lacedaemonians accordingly at once sent off a few vessels with Cnemus, who was still high admiral, and the heavy infantry on board; and sent round orders for the fleet to equip as quickly as possible and sail to Leucas. The Corinthians were the most forward in the business; the Ambraciots being a colony of theirs. While the ships from Corinth, Sicyon, and the neighbourhood were getting ready, and those from Leucas, Anactorium, and Ambracia, which had arrived before, were waiting for them at Leucas, Cnemus and his thousand heavy infantry had run into the gulf, giving the slip to Phormio, the commander of the Athenian squadron stationed off Naupactus, and began at once to prepare for the land expedition. The Hellenic troops with him consisted of the Ambraciots, Leucadians, and Anactorians, and the thousand Peloponnesians with whom he came; the barbarian of a thousand Chaonians, who, belonging to a nation that has no king, were led by Photys and Nicanor, the two members of the royal family to whom the chieftainship for that year had been confided. With the Chaonians came also some Thesprotians, like them without a king, some Molossians and Atintanians led by Sabylinthus, the guardian of King Tharyps who was still a minor, and some Paravaeans, under their king Oroedus, accompanied by a thousand Orestians, subjects of King Antichus and placed by him under the command of Oroedus. There were also a thousand Macedonians sent by Perdiccas without the knowledge of the Athenians, but they arrived too late. With this force Cnemus set out, without waiting for the fleet from Corinth. Passing through the territory of Amphilochian Argos, and sacking the open village of Limnaea, they advanced to Stratus the Acarnanian capital; this once taken, the rest of the country, they felt convinced, would speedily follow.

The Acarnanians, finding themselves invaded by a large army by land, and from the sea threatened by a hostile fleet, made no combined attempt at resistance, but remained to defend their homes, and sent for help to Phormio, who replied that, when a fleet was on the point of sailing from Corinth, it was impossible for him to leave Naupactus unprotected. The Peloponnesians meanwhile and their allies advanced upon Stratus in three divisions, with the intention of encamping near it and attempting the wall by force if they failed to succeed by negotiation. The order of march was as follows: the centre was occupied by the Chaonians and the rest of the barbarians, with the Leucadians and Anactorians and their followers on the right, and Cnemus with the Peloponnesians and Ambraciots on the left; each division being a long way off from, and sometimes even out of sight of, the others. The Hellenes advanced in good order, keeping a look-out till they encamped in a good position; but the Chaonians, filled with self-confidence, and having the highest character for courage among the tribes of that part of the continent, without waiting to occupy their camp, rushed on with the rest of the barbarians, in the idea that they should take the town by assault and obtain the sole glory of the enterprise. While they were coming on, the Stratians, becoming aware how things stood, and thinking that the defeat of this division would considerably dishearten the Hellenes behind it, occupied the environs of the town with ambuscades, and as soon as they approached engaged them at close quarters from the city and the ambuscades. A panic seizing the Chaonians, great numbers of them were slain; and as soon as they were seen to give way the rest of the barbarians turned and fled. Owing to the distance by which their allies had preceded them, neither of the Hellenic divisions knew anything of the battle, but fancied they were hastening on to encamp. However, when the flying barbarians broke in upon them, they opened their ranks to receive them, brought their divisions together, and stopped quiet where they were for the day; the Stratians not offering to engage them, as the rest of the Acarnanians had not yet arrived, but contenting themselves with slinging at them from a distance, which distressed them greatly, as there was no stirring without their armour. The Acarnanians would seem to excel in this mode of warfare.

As soon as night fell, Cnemus hastily drew off his army to the river Anapus, about nine miles from Stratus, recovering his dead next day under truce, and being there joined by the friendly Oeniadae, fell back upon their city before the enemy’s reinforcements came up. From hence each returned home; and the Stratians set up a trophy for the battle with the barbarians.

Meanwhile the fleet from Corinth and the rest of the confederates in the Crissaean Gulf, which was to have co-operated with Cnemus and prevented the coast Acarnanians from joining their countrymen in the interior, was disabled from doing so by being compelled about the same time as the battle at Stratus to fight with Phormio and the twenty Athenian vessels stationed at Naupactus. For they were watched, as they coasted along out of the gulf, by Phormio, who wished to attack in the open sea. But the Corinthians and allies had started for Acarnania without any idea of fighting at sea, and with vessels more like transports for carrying soldiers; besides which, they never dreamed of the twenty Athenian ships venturing to engage their forty-seven. However, while they were coasting along their own shore, there were the Athenians sailing along in line with them; and when they tried to cross over from Patrae in Achaea to the mainland on the other side, on their way to Acarnania, they saw them again coming out from Chalcis and the river Evenus to meet them. They slipped from their moorings in the night, but were observed, and were at length compelled to fight in mid passage. Each state that contributed to the armament had its own general; the Corinthian commanders were Machaon, Isocrates, and Agatharchidas. The Peloponnesians ranged their vessels in as large a circle as possible without leaving an opening, with the prows outside and the sterns in; and placed within all the small craft in company, and their five best sailers to issue out at a moment’s notice and strengthen any point threatened by the enemy.

The Athenians, formed in line, sailed round and round them, and forced them to contract their circle, by continually brushing past and making as though they would attack at once, having been previously cautioned by Phormio not to do so till he gave the signal. His hope was that the Peloponnesians would not retain their order like a force on shore, but that the ships would fall foul of one another and the small craft cause confusion; and if the wind should blow from the gulf (in expectation of which he kept sailing round them, and which usually rose towards morning), they would not, he felt sure, remain steady an instant. He also thought that it rested with him to attack when he pleased, as his ships were better sailers, and that an attack timed by the coming of the wind would tell best. When the wind came down, the enemy’s ships were now in a narrow space, and what with the wind and the small craft dashing against them, at once fell into confusion: ship fell foul of ship, while the crews were pushing them off with poles, and by their shouting, swearing, and struggling with one another, made captains’ orders and boatswains’ cries alike inaudible, and through being unable for want of practice to clear their oars in the rough water, prevented the vessels from obeying their helmsmen properly. At this moment Phormio gave the signal, and the Athenians attacked. Sinking first one of the admirals, they then disabled all they came across, so that no one thought of resistance for the confusion, but fled for Patrae and Dyme in Achaea. The Athenians gave chase and captured twelve ships, and taking most of the men out of them sailed to Molycrium, and after setting up a trophy on the promontory of Rhium and dedicating a ship to Poseidon, returned to Naupactus. As for the Peloponnesians, they at once sailed with their remaining ships along the coast from Dyme and Patrae to Cyllene, the Eleian arsenal; where Cnemus, and the ships from Leucas that were to have joined them, also arrived after the battle at Stratus.

The Lacedaemonians now sent to the fleet to Cnemus three commissioners—Timocrates, Bradidas, and Lycophron—with orders to prepare to engage again with better fortune, and not to be driven from the sea by a few vessels; for they could not at all account for their discomfiture, the less so as it was their first attempt at sea; and they fancied that it was not that their marine was so inferior, but that there had been misconduct somewhere, not considering the long experience of the Athenians as compared with the little practice which they had had themselves. The commissioners were accordingly sent in anger. As soon as they arrived they set to work with Cnemus to order ships from the different states, and to put those which they already had in fighting order. Meanwhile Phormio sent word to Athens of their preparations and his own victory, and desired as many ships as possible to be speedily sent to him, as he stood in daily expectation of a battle. Twenty were accordingly sent, but instructions were given to their commander to go first to Crete. For Nicias, a Cretan of Gortys, who was proxenus of the Athenians, had persuaded them to sail against Cydonia, promising to procure the reduction of that hostile town; his real wish being to oblige the Polichnitans, neighbours of the Cydonians. He accordingly went with the ships to Crete, and, accompanied by the Polichnitans, laid waste the lands of the Cydonians; and, what with adverse winds and stress of weather wasted no little time there.

While the Athenians were thus detained in Crete, the Peloponnesians in Cyllene got ready for battle, and coasted along to Panormus in Achaea, where their land army had come to support them. Phormio also coasted along to Molycrian Rhium, and anchored outside it with twenty ships, the same as he had fought with before. This Rhium was friendly to the Athenians. The other, in Peloponnese, lies opposite to it; the sea between them is about three-quarters of a mile broad, and forms the mouth of the Crissaean gulf. At this, the Achaean Rhium, not far off Panormus, where their army lay, the Peloponnesians now cast anchor with seventy-seven ships, when they saw the Athenians do so. For six or seven days they remained opposite each other, practising and preparing for the battle; the one resolved not to sail out of the Rhia into the open sea, for fear of the disaster which had already happened to them, the other not to sail into the straits, thinking it advantageous to the enemy, to fight in the narrows. At last Cnemus and Brasidas and the rest of the Peloponnesian commanders, being desirous of bringing on a battle as soon as possible, before reinforcements should arrive from Athens, and noticing that the men were most of them cowed by the previous defeat and out of heart for the business, first called them together and encouraged them as follows:

“Peloponnesians, the late engagement, which may have made some of you afraid of the one now in prospect, really gives no just ground for apprehension. Preparation for it, as you know, there was little enough; and the object of our voyage was not so much to fight at sea as an expedition by land. Besides this, the chances of war were largely against us; and perhaps also inexperience had something to do with our failure in our first naval action. It was not, therefore, cowardice that produced our defeat, nor ought the determination which force has not quelled, but which still has a word to say with its adversary, to lose its edge from the result of an accident; but admitting the possibility of a chance miscarriage, we should know that brave hearts must be always brave, and while they remain so can never put forward inexperience as an excuse for misconduct. Nor are you so behind the enemy in experience as you are ahead of him in courage; and although the science of your opponents would, if valour accompanied it, have also the presence of mind to carry out at in emergency the lesson it has learnt, yet a faint heart will make all art powerless in the face of danger. For fear takes away presence of mind, and without valour art is useless. Against their superior experience set your superior daring, and against the fear induced by defeat the fact of your having been then unprepared; remember, too, that you have always the advantage of superior numbers, and of engaging off your own coast, supported by your heavy infantry; and as a rule, numbers and equipment give victory. At no point, therefore, is defeat likely; and as for our previous mistakes, the very fact of their occurrence will teach us better for the future. Steersmen and sailors may, therefore, confidently attend to their several duties, none quitting the station assigned to them: as for ourselves, we promise to prepare for the engagement at least as well as your previous commanders, and to give no excuse for any one misconducting himself. Should any insist on doing so, he shall meet with the punishment he deserves, while the brave shall be honoured with the appropriate rewards of valour.”

The Peloponnesian commanders encouraged their men after this fashion. Phormio, meanwhile, being himself not without fears for the courage of his men, and noticing that they were forming in groups among themselves and were alarmed at the odds against them, desired to call them together and give them confidence and counsel in the present emergency. He had before continually told them, and had accustomed their minds to the idea, that there was no numerical superiority that they could not face; and the men themselves had long been persuaded that Athenians need never retire before any quantity of Peloponnesian vessels. At the moment, however, he saw that they were dispirited by the sight before them, and wishing to refresh their confidence, called them together and spoke as follows:
