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 succor each other.
The Aetolian disaster, which had been mainly caused by the wood, had not a little to do with these reflections.
