This battle was not only remarkable for its desperate fighting and bloody character, but for the fact that the complete and overwhelming defeat of the Athenians was the termination of their existence as a naval power. An Athenian fleet had been despatched to the assistance of the small Greek Republic of Ægesta, near the western end of Sicily, then threatened by Syracuse. The Athenian fleet numbered one hundred and thirty-four triremes, 25,000 seamen and soldiers, beside transports with 6000 spearmen and a proportionate force of archers and slingers. This considerable armament was designed to coöperate not only in the reduction of Syracuse, the implacable enemy of the Ægestans, but also to endeavor to subdue the whole of the large, rich and beautiful island of Sicily, at that time the granary and vineyard of the Mediterranean. The Greek fleet drew near its destination in fine order, and approached and entered Syracuse with trumpets sounding and flags displayed, while the soldiers and sailors, accustomed to a long succession of victories, and regarding defeat as impossible, rent the air with glad shouts. Syracuse is a large and perfect harbor; completely landlocked, and with a narrow entrance. The Sicilians, entirely unprepared to meet the veteran host thus suddenly precipitated upon them, looked upon these demonstrations with gloomy forebodings. Fortunately for their independence, they had wise and brave leaders, while the commander of the great Athenian fleet was wanting in decision of character and in the ability to combine his forces and move quickly; a necessity in such an enterprise as his. It therefore happened that the tables were turned, and the proud invaders were eventually blockaded in the harbor of Syracuse, the people obstructing the narrow entrance so as to prevent escape, while the country swarmed with the levies raised to resist the invaders by land, and to cut them off from all supplies. In the meantime the Greeks had seized a spot on the shores of the harbor, built a dock yard, and constructed a fortified camp. Such being the state of affairs, a prompt and energetic movement on the part of the Athenians became necessary to save them from starvation. Nikias, their commander-in-chief, entrusted the fleet to Demosthenes, Menander, and Euthydemus, and prepared to fight a decisive battle. Taught by recent partial encounters that the beaks of the Syracusan triremes were more powerful and destructive than those of his own vessels, he instructed his captains to avoid ramming as much as possible, and to attack by boarding. His ships were provided with plenty of grappling irons, so that the Sicilians could be secured as soon as they rammed the Greek vessels, when a mass of veteran Greeks was to be thrown on board, and the islanders overcome in a hand-to-hand fight.
