After he had settled everything in the assembly, and the Athenians had voted him the command of the expedition, he chose as his colleague Demosthenes, one of the generals at Pylos, and pushed forward the preparations for his voyage. His choice fell upon Demosthenes because he heard that he was contemplating a descent on the island; the soldiers distressed by the difficulties of the position, and rather besieged than besiegers, being eager to fight it out, while the firing of the island had increased the confidence of the general. He had been at first afraid, because the island having never been inhabited was almost entirely covered with wood and without paths, thinking this to be in the enemy’s favour, as he might land with a large force, and yet might suffer loss by an attack from an unseen position. The mistakes and forces of the enemy the wood would in a great measure conceal from him, while every blunder of his own troops would be at once detected, and they would be thus able to fall upon him unexpectedly just where they pleased, the attack being always in their power. If, on the other hand, he should force them to engage in the thicket, the smaller number who knew the country would, he thought, have the advantage over the larger who were ignorant of it, while his own army might be cut off imperceptibly, in spite of its numbers, as the men would not be able to see where to succour each other. The Aetolian disaster, which had been mainly caused by the wood, had not a little to do with these reflections. Meanwhile, one of the soldiers who were compelled by want of room to land on the extremities of the island and take their dinners, with outposts fixed to prevent a surprise, set fire to a little of the wood without meaning to do so; and as it came on to blow soon afterwards, almost the whole was consumed before they were aware of it. Demosthenes was now able for the first time to see how numerous the Lacedaemonians really were, having up to this moment been under the impression that they took in provisions for a smaller number; he also saw that the Athenians thought success important and were anxious about it, and that it was now easier to land on the island, and accordingly got ready for the attempt, sent for troops from the allies in the neighbourhood, and pushed forward his other preparations. At this moment Cleon arrived at Pylos with the troops which he had asked for, having sent on word to say that he was coming. The first step taken by the two generals after their meeting was to send a herald to the camp on the mainland, to ask if they were disposed to avoid all risk and to order the men on the island to surrender themselves and their arms, to be kept in gentle custody until some general convention should be concluded.
