The fleet, guided all the time by Hippias, passed on, and finally entered the strait between the island of Euboea and the main land to the northward of Athens. Here, after some operations on the island, the Persians finally brought their ships into a port on the Athenian side, and landed. Hippias made all the arrangements, and superintended the disembarkation. In the mean time, all was confusion and dismay in the city of Athens. The government, as soon as they heard of the approach of this terrible danger, had sent an express to the city of Sparta, asking for aid. The aid had been promised, but it had not yet arrived. The Athenians gathered together all the forces at their command on the northern side of the city, and were debating the question, with great anxiety and earnestness, whether they should shut themselves up within the walls, and await the onset of their enemies there, or go forth to meet them on the way. The whole force which the Greeks could muster consisted of but about ten thousand men, while the Persian host contained over a hundred thousand. It seemed madness to engage in a contest on an open field against such an overwhelming disparity of numbers. A majority of voices were, accordingly, in favor of remaining within the fortifications of the city, and awaiting an attack. The command of the army had been intrusted, not to one man, but to a commission of three generals, a sort of triumvirate, on whose joint action the decision of such a question devolved. Two of the three were in favor of taking a defensive position; but the third, the celebrated Miltiades, was so earnest and so decided in favor of attacking the enemy themselves, instead of waiting to be attacked, that his opinion finally carried the day, and the other generals resigned their portion of authority into his hands, consenting that he should lead the Greek army into battle, if he dared to take the responsibility of doing so.
